NVIDIA GeForce RTX 4080 Could Get 23 Gbps GDDR6X Memory with 340 Watt Total Board Power

NVIDIA's upcoming GeForce RTX 40 series graphics cards are less than two months from the official launch. As we near the final specification draft, we are constantly getting updates from hardware leakers claiming that the specification is ever-changing. Today, @kopite7kimi has updated his GeForce RTX 4080 GPU predictions with some exciting changes. First off, the GPU memory will get an upgrade over the previously believed specification. Before, we thought that the SKU used GDDR6X running at 21 Gbps; however, now, it is assumed that it uses a 23 Gbps variant. Faster memory will definitely result in better overall performance, and we are yet to see what it can achieve with overclocking.

Next, another update for NVIDIA GeForce RTX 4080 comes with the SKU's total board power (TBP). Previously we believed it came with a 420 Watt TBP; however, the sources of kopite7kimi claim that it has a 340 Watt TBP. This 60 Watt reduction is rather significant and could be attributed to NVIDIA's optimization to have the most efficient design possible.

Ryzen 7000 Said to Have a DDR5-6000 Memory "Sweet Spot"

If you remember, there were quite a lot of discussions about memory speed "sweet spots" for both the Ryzen 3000- and Ryzen 5000-series, with the user experience not always meeting AMD's sweet spot for memory clocks. Now details of the Ryzen 7000-series memory sweet spot has arrived courtesy of Wccftech and the speed is said to be DDR5-6000. This is 400 MHz higher than the apparent official maximum memory clock speed of DDR5-5600, but as we know, the manufacturer's max memory clock is rarely the actual max. In AMD's case, things obviously work a bit differently, as the Infinity Fabric clock should ideally run at a 1:1 ratio with the memory in the case of the AM4 platform, to deliver best possible system performance and memory latencies.

That said, as we're using DDR memory, the actual clocks are only half of the memory speeds, so the IF clock is operating at no more than 2000 MHz if the memory is DDR4-4000. However, if the same applies to the Ryzen 7000-series, it appears that AMD has managed to bump the IF clocks by a not insignificant 1000 MHz, as the IF fabric would now be operating at up to 3000 MHz. This could see the Ryzen 7000-series offering better memory latencies than Intel's Alder Lake and upcoming Raptor Lake CPUs, as Intel is running DDR5 memory at a 2:1 ratio or a 4:1 ratio. AMD is said to still have a 2:1 ratio as well, but as with the AM4 CPUs, this offers worse overall performance.

Update 11:49 UTC: Yuri Bubliy aka @1usmus has confirmed on Twitter that the max IF frequency of 3000 MHz and it seems like AMD has added a range of new memory and bus related features to the AM5 platform, going by the additional features he posted.

AMD Ryzen 7000 Series Processor Runs Phison PCIe 5.0 SSD with Micron 232-Layer NAND Flash

During this year's Flash Memory Summit, Phison, a company known for SSD controllers and now flash drives, demonstrated a system running AMD Ryzen 7000 series processors based on Zen 4 architecture. What is interesting about the shown specification is that the system was running an engineering sample of an upcoming Zen 4-based CPU with the latest storage technologies at impressive speeds. Using a Phison PS5026-E26 SSD controller, also called E26, the PCIe 5.0 SSD is powered by Micron's latest 232-layer TLC NAND flash. This new NAND technology will also bring greater densities to the market by promising higher endurance, higher read/write speeds, and better efficiency.

With AMD's upcoming AM5 platform, support for PCIe 5.0 SSDs is a welcome addition. And we today have some preliminary tests that show just how fast these SSDs can run. In CrystalDiskMark 8.0.4, it achieved over 10 GB/s in both read and write. We know that the E26 controller is capable of 12 GB/s speeds, so more fine-tuning is needed. Being an early sample, we expect final specifications to be better. The system is powered by an engineering sample of a six-core, twelve-threaded Zen 4 CPU running at unknown clocks, codenamed 100-000000593-20_Y. We can expect to see more of this technology once AMD's AM5 platform lands and Phison-powered SSDs hit the shelves in September.

AMD Ryzen 7000 Shown with DDR5-6400 Memory Speed

An alleged AMD Ryzen 7000 pre-release sample was shown running DDR5-6400 memory speed, which is already a 23 percent memory overclock on top of the DDR5-5200 native memory clock speed support. We've known since April that the Ryzen 7000 "Zen 4" processors are being designed with a focus on good memory overclocking headroom, and this is the first instance of an enthusiast-class memory speed on this platform. The feat was pulled off by Toppc, a professional overclocker affiliated with MSI.

The most interesting aspect of this feat is the density. The machine is shown featuring 64 GB of memory—something currently only doable with 32 GB quad-rank (double-sided) DIMMs; or by populating all four slots on the motherboard with 16 GB dual-rank (single-sided) DIMMs, or a 2DPC setup, which would make this feat all the more impressive. The CPU-Z screenshot by Toppc reveals a DRAM clock of 3202 MHz (DDR5-6404), and timings of 32-38-38-96. The Socket AM5 Ryzen 7000 desktop processors only support DDR5 memory type (no backwards-compatibility with DDR4), and AMD states that since it is betting solely on DDR5 (with no DDR4 sidewheels), enthusiasts can expect a good memory overclocking experience.

Sapphire Intros Radeon RX 6500 XT Graphics Card with Off-Spec 8GB Memory

Sapphire introduced one of the first Radeon RX 6500 XT graphics cards in the retail channel to feature 8 GB of video memory, double that of the 4 GB standard for the SKU. The Sapphire Pulse RX 6500 XT 8 GB resembles the company's standard Pulse RX 6500 XT in design. At this point it's unclear how Sapphire went about deploying 8 GB of memory with the RX 6500 XT, given its narrow 64-bit GDDR6 memory interface.

Sapphire probably used four 16 Gbit memory chips, with two chips piggybacking a 32-bit memory channel. This would finally put the metal backplate to some use, as two of the chips could be located on the reverse side of the PCB. The memory ticks at the same 18 Gbps speed as the standard RX 6500 XT. The card's typical board power is increased to 130 W, up from the 107 W AMD reference. This is probably because the added memory chips, as well as slightly increased clock speeds of 2685 MHz (game clock), vs. 2615 MHz reference. The company didn't announce pricing or availability, but is planning a global launch for this card.

CXL Memory Pooling will Save Millions in DRAM Cost

Hyperscalers such as Microsoft, Google, Amazon, etc., all run their cloud divisions with a specific goal. To provide their hardware to someone else in a form called instance and have the user pay for it by the hour. However, instances are usually bound by a specific CPU and memory configuration, which you can not configure yourself. But instead, you can only choose from the few available options that are listed. For example, when selecting one virtual CPU core, you get two GB of RAM and can go as high as you want with CPU cores. However, the available RAM will also double, even though you might not need it. When renting an instance, the allocated CPU cores and memory are yours until the instance is turned off.

And it is precisely this that hyperscalers are dealing with. Many instances don't fully utilize their DRAM, making the whole data center usage inefficient. Microsoft Azure, one of the largest cloud providers, measured that 50% of all VMs never touch 50% of their rented memory. This makes memory stranded in a rented VM, making it unusable for anything else.
At Azure, we find that a major contributor to DRAM inefficiency is platform-level memory stranding. Memory stranding occurs when a server's cores are fully rented to virtual machines (VMs), but unrented memory remains. With the cores exhausted, the remaining memory is unrentable on its own, and is thus stranded. Surprisingly, we find that up to 25% of DRAM may become stranded at any given moment.

Apple M1 Chips Affected by Unpatchable "PACMAN" Exploit

Apple M1 chips are a part of the Apple Silicon family that represents a new transition to Arm-based cores with new power and performance targets for Apple devices. A portion of building a processor is designing its security enclave, and today we have evidence that M1 processors got a new vulnerability. The PACMAN is a hardware attack that can bypass Pointer Authentication (PAC) on M1 processors. Security researchers took an existing concept of Spectre and its application in the x86 realm and now applied it to the Arm-based Apple silicon. PACMAN exploits a current software bug to perform pointer authentication bypass, which may lead to arbitrary code execution.

The vulnerability is a hardware/software co-design that exploits microarchitectural construction to execute arbitrary codes. PACMAN creates a PAC Oracle to check if a specific pointer matches its authentication. It must never crash if an incorrect guess is supplied and the attack brute-forces all the possible PAC values using the PAC Oracle. To suppress crashes, PAC Oracles are delivered speculatively. And to learn if the PAC value was correct, researchers used uArch side channeling. In the CPU resides translation lookaside buffers (TLBs), where PACMAN tries to load the pointer speculatively and verify success using the prime+probe technique. TLBs are filled with minimal addresses required to supply a particular TLB section. If any address is evicted from the TLB, it is likely a load success, and the bug can take over with a falsely authenticated memory address.
