The AI data center buildout requires massive bandwidth from accelerator to accelerator and from accelerator to CPU. At the core of that bandwidth bridge is PCIe technology, which constantly needs to evolve to satisfy massive bandwidth requirements. Today, PCI-SIG, the working group behind the PCI and PCIe connector, is releasing details about the almost ready 0.9 version of the PCIe 7.0 connector and its final specifications. The latest PCIe 7.0 will bring 128 GT/s speeds, with a bi-directional bandwidth of 512 GB/s in the x16 lane configuration. Targeting applications like 800G Ethernet, AI/ML, cloud, quantum computing, hyperscalers, military/aerospace, and cloud providers all need massive bandwidth for their respective applications and use cases to work flawlessly.

Interestingly, as PCIe doubles bandwidth over the traditional three-year cadence, high bandwidth for things like storage is becoming available on fewer and fewer lanes. For example, PCIe 3.0 with x16 lanes delivers 32 GB/s of bi-directional bandwidth. And now, PCIe 7.0 delivers that same bandwidth on only a single x1 lane. Some other goals of the new PCIe 7.0 include significant improvements in channel parameters and signal integrity while enhancing power efficiency and maintaining the protocol's low-latency characteristics. All while ensuring complete backward compatibility with previous generations of the standard. Notably, the PCIe 7.0 standard uses PAM4 signaling, which was first presented for PCIe 6.0. Here is a nice PAM4 signaling primer if you want to learn more about PAM4 signaling. Below are the specifications of PCIe generations and their respective characteristics. We expect to see final version v1.0 by end of the year, and some PCIe 7.0 accelerators next year.

PCI-SIG, the consortium that governs the PCI Express I/O interconnect, released draft specification version 0.7 for the upcoming PCI-Express 7.0 standard (or PCIe Gen 7). An early-2025 release of this draft could indicate that PCIe Gen 7 gets finalized into specification version 1.0 by the end of 2025, from where implementers can pick it up to design their devices around. We are now at 32 Gbps per lane per direction with PCIe Gen 5, and PCIe Gen 6 doubles it to 64 Gbps, which would mean PCIe Gen 7 will double that further to 128 Gbps per lane per direction. PCI-Express 7.0 x1 would offer the same bandwidth as PCI-Express 3.0 x16. We could realistically expect the first computing platforms implementing PCIe Gen 7 to come out around 2027 or even 2028. PCIe forms the physical layer for a number of derivative standards, such as CXL, Thunderbolt, USB (USB 3.0 onwards), NVMe, SDexpress, CFexpress, and DMI.Many Thanks to Tumble George for the tip

Online hardware communities continue to discuss the 12VHPWR connection standard's troubled existence, while revised technology gets worked on—quietly—in the background. PCI-SIG's 12V-2x6 connector was first revealed last summer, signalling an alternative power delivery method for high-wattage graphics cards. Past TPU reports show that the 12V-2x6 16-pin design has already popped up on select NVIDIA Founders Edition cards, GeForce RTX 40 SUPER custom graphics card designs, and various new generation power supplies. Earlier today, Алексей (AKA wxnod) took to social media and posted an image of the freshly deshrouded "H++" 12V-2x6 (total design limit: 675 W) socket, as well as a shot of the familiar "H+" 12VHPWR (max. 600 W).

This fifth generation socket design largely rolled out with Team Green's GeForce RTX-40 SUPER card series, although wxnod notes that exceptions do exist: "Some AIC GeForce RTX 4070 SUPER, 4070 Ti SUPER and 4080 SUPER cards are still using the H+12VHPWR interface." The H++ identified 12V-2x6 design's power limit peaks at 675 W—a technical breakdown from last July revealed that 75 W comes from the expansion slot, while the big 600 W portion flows through the 16-pin connector. As mentioned before, 12V-2x6 debuted on a few Non-SUPER cards back in 2023, but last month's SUPER series product launch marked a more comprehensive rollout. AMD has indicated that it is considering an adoption of Gen 5 H++ in the future, but we have not heard much on that subject since last August. A new generation 16-pin PCIe 6.0 power connector design was linked to the upcoming NVIDIA RTX 50-series of "Blackwell" GPUs, but Hardware Busters has refuted rumors generated by Moore's Law is Dead. Team Green is expected to remain faithful to "H++" 12V-2x6 with the launch of next generation graphics cards.

Officially, support for resizable BAR on the Intel platform begins with the 10th Gen Core "Comet Lake," and for AMD, the Ryzen 3000 "Zen 2." It is a PCI-SIG feature that allows the software to see the entire amount of video memory on your graphics card as a single contiguous addressable block, rather than through 256 MB apertures—a workaround for the original PCI Express specification as the industry was transitioning to it from AGP. The PCI-SIG had introduced resizable BAR way back during the PCI-Express 2.0 specification (late 2000s), although none of the GPU or platform vendors of the time bothered to implement it. Resizable BAR is known to have a positive impact on performance for modern GPUs from NVIDIA and AMD; although its most profound performance impact is on the Intel Arc "Alchemist" GPUs, which suffer a large performance penalty without it.

ReBarUEFI by xCuri0 is a UEFI DXE driver mod, which requires you to know how to modify the UEFI firmware of your motherboard. The ReBarUEFI mod calls for a motherboard that implements UEFI, the older legacy BIOS won't do. The industry transitioned to UEFI in the early 2010s, roughly around the time of Intel "Sandy Bridge." UEFI DXE drivers provide basic support for the various hardware on your system. The ReBarUEFI driver informs software that the platform is capable of resizable BAR. Some motherboards may require you to enable the "Above 4G Decode" setting. The author claims that users on platforms as old as 2nd Gen Core "Sandy Bridge" have had success in getting resizable BAR to work.

Alphawave Semi (LSE: AWE), a global leader in high-speed connectivity for the world's technology infrastructure, today announced successful collaboration with Keysight Technologies, a market-leading design, emulation, and test solutions provider, demonstrating interoperability between Alphawave Semi's PCIe 6.0 64 GT/s Subsystem (PHY and Controller) Device and Keysight PCIe 6.0 64 GT/s Protocol Exerciser, negotiating a link to the maximum PCIe 6.0 data rate.

KIOXIA America, Inc. today announced that its CM7 Series and CD8P Series NVM Express (NVMe) SSDs have passed certification testing for PCI Express (PCIe) 5.0 specification and NVMe 2.0 specification compliance. Developed by PCI-SIG, the PCIe 5.0 interface specification is an upgrade that enables twice the data transfer speed and bandwidth versus the PCIe 4.0 specification - up to 14,000 Megabyte/s read throughput for a x4 lane SSD. PCIe 5.0 tests were conducted at PCI-SIG compliance workshops against PCI-SIG maintained systems, along with other leading manufacturers of PCIe products.

KIOXIA CM7 Series and CD8P Series drives can now be found on the PCI-SIG Integrator's List. Achieving compliance certification during these workshops assures users that KIOXIA drives meet the rigorous PCIe 5.0 specification requirements. KIOXIA CM7 Series and CD8P Series drives have been added to The University of New Hampshire InterOperability Laboratory's (UNH-IOL) official Integrator's List. In order to be considered for inclusion on the list, technologies must undergo conformance testing performed by the UNH-IOL through laboratory tests or during an NVMe plugfest. Successful completion of this testing provides a level of assurance that the product being tested will function properly in NVMe enabled systems and NVM Express over Fabrics (NVMe-oF) environments.

Phison Electronics, a global leader in NAND controllers and storage solutions, announced today that the company has expanded its portfolio of PCIe 5.0 high-speed transmission solutions with PCIe 5.0, CXL 2.0 compatible redriver and retimer data signal conditioning IC products.

FSP has declared that it intends to update its entire 2023 PSU product lineup to include the latest "12V-2x6" power connector (part of the ATX 3.0 standard)—harukaze5719 posted about this development earlier today, citing a Quasarzone article. We heard mid-summer about PCI-SIG plowing ahead on an all-new ATX 3.0 connector to replace the 16-pin (12+4) 12VHPWR plug. They hope to introduce some key improvements with their new design, mainly in the areas of ease-of-use and safety.

TPU staffers had hands-on time with FSP's 2023 PSU product line at their Computex 2023 booth, showcased units were equipped with 16-pin 12VHPWR (at the time). Quasarzone's report (covering a recent press conference) has the following FSP power supply families listed with updates to the new "12V-2x6" standard: Hydro G PRO 1200 W ATX 3.0, Hydro PTM X PRO ATX 3.0 and Dagger PRO ATX 3.0.

PCI-SIG today announced the formation of a new workgroup to deliver PCI Express (PCIe) technology over optical connections. The PCI-SIG Optical Workgroup intends to be optical technology-agnostic, supporting a wide range of optical technologies, while potentially developing technology-specific form factors.

"Optical connections will be an important advancement for PCIe architecture as they will allow for higher performance, lower power consumption, extended reach and reduced latency," said Nathan Brookwood, Research Fellow at Insight 64. "Many data-demanding markets and applications such as Cloud and Quantum Computing, Hyperscale Data Centers and High-Performance Computing will benefit from PCIe architecture leveraging optical connections."

A few days ago, we reported that NVIDIA and PCI-SIG have been doing some work around the existing controversial 12VHPWR power connector to make some improvements and prevent issues that happened along the way. Called 12V-2x6, the connector features minor revisions, and you can read more about it here. Today, we learn that NVIDIA has already been shipping implementations of the new 12V-2x6 connector in GeForce RTX 4070 graphics cards, confirmed by Igor's Lab. Majority of RTX 4070 cards from AIBs shipped with 8-pin PCI connector; however, it turns out that cards that didn't use the reference 12-pin connection carried a new 12V-2x6 revision.

Below, you can see the picture comparison with the connectors from the Founders Edition of GeForce RTX 4070 and RTX 4080. The new connector on the RTX 4070 has shorter sensing pins, which can detect whether the connector is fully plugged in. If not plugged all the way, the card will not draw the required maximum power load. This should, in theory, solve connector burning issues happening in the past; however, we are still left to see. In addition, we are not sure if this is the final implementation of the new connector, as the labeling refferest to it as "H+", whereas the new connector should carry the label "H++" on its module. Igor's Lab article notes, "Since the GeForce RTX 4070 FE, NVIDIA has already been using a modified 12VHPWR connector with significantly recessed pins! While the GeForce RTX 4080 Founders Edition still relies on the header from the CEM 5.0 with only 0.45 mm offset, the GeForce RTX 4070 Founders Edition has been using a modified variant with 1.7 mm inward offset since its launch, similar to the 12V-2x6 connector."

According to Igor's Lab, who has gotten their hands on a PCI-SIG draft engineer change notice, it looks like the not entirely uncontroversial 12VHPWR connector won't be long lived. The PCI-SIG is getting ready to replace it with the 12V-2x6 connector, which will be part of the ATX 3.1 spec and the PCI Express 6.0 spec. The new connector doesn't appear to have any major physical changes though, but there have been mechanical modifications, such as the sense pins having been recessed further back, to make sure a proper contact is made before higher power outputs can be requested by the GPU. The good news is that at least in the draft spec, the 12V-2x6 connector will be backwards compatible with 12VHPWR connectors.

One of the bigger changes, at least when it comes to how much power the new connector can deliver, is that there will be new 150 and 300 Watt modes in addition to the 450 and 600 Watt modes for the sense pin detection. The 12V-2x6 connector is rated for at least 9.2 Amps per pin and the new connectors will carry a H++ logo, with th older 12VHPWR connectors getting a H+ logo. The PCI-SIG has also added stricter requirements when it comes to the cable design and quality, which should hopefully prevent some of the issues the 12VHPWR implementations have suffered from. We should find out more details once the PCI-SIG has finalised the 12V-2x6 connector specification. In the meantime, you can hit up the source link for more technical drawings and details.

It appears that Western Digital is getting ready to expand its budget line of WD Blue SSDs with yet another model, this time a smaller jump from the SN570 to the SN580, compared to the jump in model numbers from the SN550 to the SN570. The drive has passed through the PCI-SIG integrators list and from that information we only know it's a PCIe 4.0 NVMe drive with a four lane interface. However, some retailers have already put up the drive for pre-order and this helps us with a few more details.

For starters, it appears that we're once again looking at drives in the 500 GB to the 2 TB range, although this doesn't mean that WD couldn't launch a 4 TB variant as well, but it seems unlikely. What we also learnt is that these product pages are place holders, as the drives are listed for the same, or higher pricing than the WD Black SN850X, which makes no sense for a budget drive which should be closer to the US$100/€100 mark than the equivalent of twice that. Another European retailer is also listing the current SN570 as being EOL:ed on the 31st of July, suggesting that the SN580 should launch around that date. The same retailer is listing the SN580 as the replacement drive under its part number, which is WDS200T3B0E for the 2 TB SKU.

PCI-SIG is pleased to share the PCI Express (PCIe) 7.0 specification, version 0.3 is now available to members.

When testing recent high-end GPU launches such as the AMD Radeon RX 6950 XT graphics card, we observed some system reboots that caused due to power-draw spikes (technically known as "excursions"). This is when a graphics card, for a brief moment, draws more power than the connector is capable of supplying, triggering the PSU's electrical protections, and causing a reboot. The new ATX 3.0 specification for the next-generation of desktop PC power supplies enable PSUs with a high tolerance for excursions, and prescribes testing standards to ensure a PSU meets the ATX 3.0 spec. Aris Mpitziopoulos (crmaris) and Jon Gerow (Jonnyguru) discovered wording in the latest Intel ATX 3.0 specification that could make you pay closer attention to reviews of ATX 3.0-spec PSU, when they're out.

In a Hardware Busters article, Mpitziopoulos clears the confusion that the ATX 3.0 power supply specs by Intel and the PCI-Express 5.0 power specification by the PCI-SIG, are mutually-inclusive—they're not. An ATX 3.0 PSU is not required to include a 12+4 pin (or 16-pin) ATX 12VHPWR connector, whether or not their nameplate Wattage is above 450 W, which means it's subjected to passing less stressful transient-response tests, particularly the ability to deal with a 200% excursion for at least 100 µs.

The upcoming Samsung 990 PRO flagship consumer SSD has recently been listed as PCIe 5.0 compliant by PCI-SIG with the entry also confirming the drive's name and M.2 interface. The upgrade to PCIe 5.0 from 4.0 doubles the available bandwidth for the card with Samsung's existing enterprise PCIe 5.0 drives reaching speeds of 13,000 MB/s significantly above the 7000 MB/s of the best PCIe 4.0 drives. The latest Intel Alder Lake systems can support PCIe 5.0 drives on select motherboards with AMD support set to arrive with the launch of Ryzen 7000 and X670/B650 motherboards. Samsung is expected to release at least 1 TB and 2 TB variants of the drive however other details such as the exact length of the card and the controller used are currently unknown.

MSI welcomes the MEG Ai1300P PCIE5 power supply unit, the world's first power supply unit to be fully ready for ATX 3.0 and PCIe 5.0. With graphics cards becoming all the more important, users must know what components to buy for their system if they are looking to upgrade. To understand why the MEG Ai1300P PCIE5 is the ultimate future-proof power supply unit, let's begin with understanding ATX 3.0.

ATX 3.0 is Intel's new specification standard for existing PSUs. In short, ATX 3.0's main purpose is to help provide more reliability, and better power efficiency and provide graphics cards up to 600 watts of power. ATX 3.0 is created in response to graphics cards' increase in performance and the ever-increasing need for power. ATX 3.0 puts heavy emphasis on power excursions to make sure high-performance graphics cards can be sustained and your system can remain stable. Thanks to ATX 3.0 there is now an increase in efficiency while idling and a new power connector is added to help achieve all the above. ATX 3.0 added a new PCIe 5.0 12VHPWR connector that features 12+4 pins instead of the traditional 6 or 8. With the new PCIe 5.0 connector, the power supply and cable can supply up to 600 watts of power.

PCI-SIG today announced that the PCI Express (PCIe ) 7.0 specification will double the data rate to 128 GT/s and is targeted for release to members in 2025. "For 30 years the guiding principle of PCI-SIG has been, 'If we build it, they will come,'" observed Nathan Brookwood, Research Fellow at Insight 64. "Early parallel versions of PCI technology accommodated speeds of hundreds of megabytes/second, well matched to the graphics, storage and networking demands of the 1990s.

In 2003, PCI-SIG evolved to a serial design that supported speeds of gigabytes/second to accommodate faster solid-state disks and 100MbE Ethernet. Almost like clockwork, PCI-SIG has doubled PCIe specification bandwidth every three years to meet the challenges of emerging applications and markets. Today's announcement of PCI-SIG's plan to double the channel's speed to 512 GB/s (bi-directionally) puts it on track to double PCIe specification performance for another 3-year cycle."

Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced that its PHY and Controller IP for the PCI Express (PCIe ) 5.0 specification in the TSMC N7, N6 and N5 process technologies have passed certification tests from PCI-SIG at the industry's first event for PCIe 5.0 specification compliance held in April. The Cadence solutions were tested to their full potential and complied with the full speed of 32GT/s for PCIe 5.0 technology. The compliance program provides designers with testing procedures to assess that the PCIe 5.0 interfaces on their system-on-chip (SoC) designs will operate as expected.

The Cadence IP for PCIe 5.0 technology consists of a PHY, companion controller and Verification IP (VIP) targeted at SoC designs for very high-bandwidth hyperscale computing, networking and storage applications. With Cadence's PHY and Controller Subsystem for PCIe 5.0 architecture, customers can design extremely power-efficient SoCs while accelerating time to market.

NVMe SSDs based on the M.2 form factor come in several different lengths today, ranging from 30 to 110 mm, although the 30 mm drives are rare and the 110 mm drives have so far been reserved for the server space. However, they've all had one thing in common, the 22 mm width, as otherwise there might be issues in terms of fitting the drives, especially in notebooks. However, it appears that the PCI-SIG snuck in a wider, 25 mm option for M.2 SDDs at the end of 2020, but seemingly forgot to mention it to anyone. The only reason we even noticed, was because Gigabyte listed its upcoming X670 and X670E motherboards as having support for 25110 SSD's, where you'd expect to see support for 2280 or 22110 drives.

An extra 3 mm in width might not sound like much, but many M.2 drives seem to be somewhat space constrained, mainly with regards to the passive components and the power regulation. It also seems like this is in preparation for PCIe 5.0 NVMe drives, where the host controller is expected to run hotter, even though it might not be as bad as initially expected. Regardless, it seems like motherboard makers are now making space for this slightly wider M.2 form factor, as well as implementing suitable cooling solutions to match. Whether we'll see drives using this slightly wider form factor or not, is still up in the air and one reason why the SSD manufacturers might choose not to go wider, is because new drives might not fit in older motherboards and laptops, if the clearance is too small.

Phison Electronics Corp., a leading provider of NAND controller and flash storage solutions, announced today a strategic collaboration with AMD and Micron to build a cooperative PCIe Gen5 ecosystem of compatible products that elevate the gaming and creator experience. Phison's role includes delivering a class-leading PCie Gen5 SSD controller - PS5026-E26 - that features nearly a 2x performance increase over the previous generation flagship while adhering to the same power limitations of the M.2 form factor.
