Curious NVIDIA GB202-200-A1 ASIC Spy Shot Hints at RTX TITAN Blackwell

Is NVIDIA reviving the RTX TITAN brand of halo-segment graphics cards with "Blackwell"? A curious-looking GB202-200-A1 spy-shot making rounds on ChilHell hints at the possibility. The upcoming GeForce RTX 5090 is the company's flagship product from the RTX 50-series "Blackwell" generation, although it does not max out the 4 nm "GB202" silicon on which it is based. The RTX 5090 enables 170 out of the 192 SM (streaming multiprocessors) physically present on the "GB202." This leaves NVIDIA with a lot of room to carve out either a halo-segment SKU such as the RTX TITAN Blackwell, or a Pro-Vis (professional visualization) product that also targets the AI research community.

NVIDIA's top Pro-Vis product tended to have more SMs enabled than the top GeForce RTX product, while having lower clock speeds, so its target users have access to more FP64-capable CUDA cores, more Tensor cores, etc. However, over the past two generations, NVIDIA discontinued the practice of giving its RTX GPUs large numbers of FP64 cores that are disabled on GeForce RTX products, to make die-space for the Tensor cores. This hence makes it more likely that a maxed-out "GB202" is the RTX TITAN Blackwell, and not a Pro-Vis product.

ZOTAC Publishes GeForce RTX 5090 Tech Specs on Product Pages

ZOTAC's website has been updated with technical specifications for its GeForce RTX 5090 GPU-based custom models—the Hong Kong-based hardware company is perhaps the first NVIDIA board partner to publicly disclose these details. According to VideoCardz, this discovery was made by a loyal reader—product pages for SOLID, SOLID OC and AMP Extreme INFINITY seemed to have appeared online within the past couple of days. A resultant report suggests that Team Green has only recently communicated (potentially) finalized specs with its AIBs.

The aforementioned discoverer of ZOTAC's GeForce RTX 5090 spec sheets noticed an unusual memory clock figure on the SOLID OC model's listing—30 Gbps instead of 28 Gbps. This was an error—ZOTAC has since amended that particular data point (see VideoCardz's screenshots below)—their presumably more expensive AMP Extreme INFINITY card's memory clock spec is set at 28 Gbps. Interestingly, ZOTAC's upcoming flagship is the first example of an NVIDIA GPU configured with a power consumption rating of 600 W. It is not immediately apparent whether this TDP figure is an out-of-the-box default—VideoCardz reckons that the GeForce RTX 5090 AMP Extreme INFINITY will arrive with dual-BIOS functionality. A high-performance mode could be user selected. Will rival flagship GeForce RTX 5090 custom cards roll out with similar TDPs? TechPowerUp anticipates the emergence of pre-launch technical details—from other brands/manufacturers—over the next two weeks.

NVIDIA GeForce RTX 5090 Founders Edition Hands On, Taken Apart

At the 2025 International CES, we went hands on with the new NVIDIA GeForce RTX 5090 Founders Edition "Blackwell" graphics card. This thing is huge—longer and taller than the RTX 4090 FE, and yet just 2 slots thick. This is because NVIDIA's designers have figured out that the heat dissipation area of the heatsink lost to thinning the card can be recovered by stretching it in other directions. The card retains the essential aesthetic of Founders Edition cards from the past two generations going back to the RTX 30-series, but changes the concept of the dual-axial flow-through.

While past generations used an intake fan on one side, blowing onto the PCB, and another fan at the tail end of the backplate pull air through the heatsink and out the back, the RTX 5090 FE has two large fans, both of which blow cold air through the heatsink, and out the back of the card. The PCB is located in the center of the card, and relies on a set of breakout PCBs for host interface and display outputs.

First NVIDIA GeForce RTX 5090 GPU with 32 GB GDDR7 Memory Leaks Ahead of CES Keynote

NVIDIA's unannounced GeForce RTX 5090 graphics card has leaked, confirming key specifications of the next-generation GPU. Thanks to exclusive information from VideoCardz, we can see the packaging of Inno3D's RTX 5090 iChill X3 model, which confirms that the graphics card will feature 32 GB of GDDR7 memory. The leaked materials show that Inno3D's variant will use a 3.5-slot cooling system, suggesting significant cooling requirements for the flagship card. According to earlier leaks, the RTX 5090 will be based on the GB202 GPU and include 21,760 CUDA cores. The card's memory system is a significant upgrade, with its 32 GB of GDDR7 memory running on a 512-bit memory bus at 28 Gbps, capable of delivering nearly 1.8 TB/s of bandwidth. This represents twice the memory capacity of the upcoming RTX 5080, which is expected to ship with 16 GB capacity but 30 Gbps GDDR7 modules.

Power consumption has increased significantly, with the RTX 5090's TDP rated at 575 W and TGP of 600 W, marking a 125-watt increase over the previous RTX 4090 in raw TDP. NVIDIA is scheduled to hold its CES keynote today at 06:30 pm PT time, where the company is expected to announce several new graphics cards officially. The lineup should include the RTX 5090, RTX 5080, RTX 5070 Ti, RTX 5070, and an RTX 5090D model specifically for the Chinese market. Early indications are that the RTX 5080 will be the first card to reach consumers, with a planned release date of January 21st. Release dates for other models, including the flagship RTX 5090, have not yet been confirmed. The RTX 5090 is currently the only card in the RTX 50 series planned to use the GB202 GPU. Pricing information and additional specifications are expected to be revealed during the upcoming announcement.

NVIDIA GeForce RTX 5090 Features 575 W TDP, RTX 5080 Carries 360 W TDP

According to two of the most accurate leakers, kopite7kimi and hongxing2020, NVIDIA's GeForce RTX 5090 and RTX 5080 will feature 575 W and 360 W TDP, respectively. Previously, rumors have pointed out that these GPU SKUs carry 600 W and 400 W TGPs, which translates into total graphics power, meaning that an entire GPU with its RAM and everything else draws a certain amount of power. However, TDP (thermal design power) is a more specific value attributed to the GPU die or the specific SKU in question. According to the latest leaks, 575 Watts are dedicated to the GB202-300-A1 GPU die in the GeForce RTX 5090, while 25 Watts are for GDDR7 memory and other components on the PCB.

For the RTX 5080, the GB203-400-A1 chip is supposedly drawing 360 Watts of power alone, while 40 Watts are set aside for GDDR7 memory and other components in the PC. The lower-end RTX 5080 uses more power than the RTX 5090 because its GDDR7 memory modules reportedly run at 30 Gbps, while the RTX 5090 uses GDDR7 memory modules with 28 Gbps speeds. Indeed, the RTX 5090 uses more modules or higher capacity modules, but the first-generation GDDR7 memory could require more power to reach the 30 Gbps threshold. Hence, more power is set aside for that. In future GDDR7 iterations, more speed could be easily achieved without much more power.

NVIDIA GeForce RTX 5090 Features 16+6+7 Phase Power Delivery on 14-Layer PCB

Fresh details have surfaced about NVIDIA's upcoming flagship "Blackwell" graphics card, the GeForce RTX 5090, suggesting power delivery and board design changes compared to its predecessors. According to Benchlife, the new Blackwell-based GPU will feature a new 16+6+7 power stage design, departing from the RTX 4090's 20+3 phase configuration. The report confirms earlier speculation about the card's power requirements, indicating a TGP of 600 watts. This specification refers to the complete power allocation for the graphics subsystem, though the actual TDP of the GB202 chip might be lower. The RTX 5090 will ship with 32 GB of next-generation GDDR7 memory and utilize a 14-layer PCB, possibly due to the increased complexity of GDDR7 memory modules and power delivery. Usually, GPUs max out at 12 layers for high-end overclocking designs.

The upcoming GPU will fully embrace modern connectivity standards, featuring PCI Express 5.0 x16 interface compatibility and implementing a 12V-2×6 power connector design. We spotted an early PNY RTX 5090 model with 40 capacitors but an unclear power delivery setup. With additional power phases and more PCB layers, NVIDIA is pushing the power delivery and signal integrity boundaries for its next-generation flagship. While these specifications paint a picture of a powerful gaming and professional graphics solution, questions remain about the broader RTX 50 series lineup. The implementation of the 12V-2×6 connector across different models, particularly those below 200 W, remains unclear, so we have to wait for the CES-rumored launch.

NVIDIA GeForce RTX 5090 Powered by "GB202" Silicon, 512-bit GDDR7, ASIC Pictured

Here is the first picture of what is very likely the GeForce RTX 5090 "Blackwell," the successor to the RTX 4090 "Ada." The picture, its massive GPU, and layout appear to confirm the weekend's bare PCB leak. The RTX 5090 is powered by the "GB202" silicon, the largest gaming GPU based on the "Blackwell" graphics architecture. The silicon in the picture has the ASIC code "GB202-300-A1." From this ASIC code, we can deduce that the RTX 5090 may not max out the silicon (i.e. enable all SM present on it), as maxed-out NVIDIA ASICs tend to have the variant designation "450."

The "GB202" ASIC is surrounded by sixteen GDDR7 memory chips, which reportedly make the 32 GB memory size of the RTX 5090. The chip count, coupled with the large GPU package size (high pin-count), confirm that the "GB202" features a 512-bit wide memory bus. Assuming a memory speed of 28 Gbps, this memory bus should yield a stellar memory bandwidth of 1,792 GB/s. The GPU and memory are surrounded by the card's 24-phase VRM solution. This draws power from a single 16-pin 12V-2x6 power connector. NVIDIA will likely max out the 600 W continuous power-delivery capability of the connector, and give the card a TGP of around 500-550 W, if not more.

NVIDIA GeForce RTX 5090 PCB Pictured, Massive GPU Die and 16-Chip Memory Configuration

NVIDIA's GeForce RTX 5090 graphics card printed circuit board has allegedly been shown in the flesh, showing the memory layout and some interesting engineering choices. The custom PCB variant (non-Founders Edition) houses more than 40 capacitors, which is perhaps not standard on the FE reference board, and 16 GDDR7 memory modules. The leaked PCB, which extends beyond standard dimensions and traditional display connector configurations, is reportedly based on NVIDIA's PG145 reference design. The memory modules are distributed systematically: five on the left, two below, five on the right, and four above the GPU die. The interface is PCIe 5.0 x16.

As NVIDIA has reportedly designated 32 GB GDDR7 memory capacity for these cards, this roughly translates into 16 x 2 GB GDDR7 memory modules. At the heart of the card lies what sources claim to be the GB202 GPU, measuring 24×31 mm within a 63×56 mm package. Power delivery uses a 16-pin 12V-6x2 power connector, as expected. The entire PCB features only a single power connector, so the 16-pin 12V-2x6, but with an updated PCIe 6.0 CEM specification, is the logical choice.

NVIDIA GeForce RTX 5090 and RTX 5080 Specifications Surface, Showing Larger SKU Segmentation

Thanks to the renowned NVIDIA hardware leaker kopite7Kimi on X, we are getting information about the final versions of NVIDIA's first upcoming wave of GeForce RTX 50 series "Blackwell" graphics cards. The two leaked GPUs are the GeForce RTX 5090 and RTX 5080, which now feature a more significant gap between xx80 and xx90 SKUs. For starters, we have the highest-end GeForce RTX 5090. NVIDIA has decided to use the GB202-300-A1 die and enabled 21,760 FP32 CUDA cores on this top-end model. Accompanying the massive 170 SM GPU configuration, the RTX 5090 has 32 GB of GDDR7 memory on a 512-bit bus, with each GDDR7 die running at 28 Gbps. This translates to 1,568 GB/s memory bandwidth. All of this is confined to a 600 W TGP.

When it comes to the GeForce RTX 5080, NVIDIA has decided to further separate its xx80 and xx90 SKUs. The RTX 5080 has 10,752 FP32 CUDA cores paired with 16 GB of GDDR7 memory on a 256-bit bus. With GDDR7 running at 28 Gbps, the memory bandwidth is also halved at 784 GB/s. This SKU uses a GB203-400-A1 die, which is designed to run within a 400 W TGP power envelope. For reference, the RTX 4090 has 68% more CUDA cores than the RTX 4080. The rumored RTX 5090 has around 102% more CUDA cores than the rumored RTX 5080, which means that NVIDIA is separating its top SKUs even more. We are curious to see at what price point NVIDIA places its upcoming GPUs so that we can compare generational updates and the difference between xx80 and xx90 models and their widened gaps.

Possible Specs of NVIDIA GeForce "Blackwell" GPU Lineup Leaked

Possible specifications of the various NVIDIA GeForce "Blackwell" gaming GPUs were leaked to the web by Kopite7kimi, a reliable source with NVIDIA leaks. These are specs of the maxed out silicon, NVIDIA will carve out several GeForce RTX 50-series SKUs based on these chips, which could end up with lower shader counts than those shown here. We've known from older reports that there will be five chips in all, the GB202 being the largest, followed by the GB203, the GB205, the GB206, and the GB207. There is a notable absence of a successor to the AD104, GA104, and TU104, because NVIDIA is trying a slightly different way to approach the performance segment with this generation.

The GB202 is the halo segment chip that will drive the possible RTX 5090 (RTX 4090 successor). This chip is endowed with 192 streaming multiprocessors (SM), or 96 texture processing clusters (TPCs). These 96 TPCs are spread across 12 graphics processing clusters (GPCs), which each have 8 of them. Assuming that "Blackwell" has the same 256 CUDA cores per TPC that the past several generations of NVIDIA gaming GPUs have had, we end up with a total CUDA core count of 24,576. Another interesting aspect about this mega-chip is memory. The GPU implements the next-generation GDDR7 memory, and uses a mammoth 512-bit memory bus. Assuming the 28 Gbps memory speed that was being rumored for NVIDIA's "Blackwell" generation, this chip has 1,792 GB/s of memory bandwidth on tap!

NVIDIA to Stick to Monolithic GPU Dies for its GeForce "Blackwell" Generation

NVIDIA's GeForce "Blackwell" generation of gaming GPUs will stick to being traditional monolithic die chips. The company will not build its next generation of chips as either disaggregated devices, or multi-chip modules. Kopite7kimi, a reliable source with NVIDIA leaks, says that the largest GPU in the generation, the "GB202," is based on a physically monolithic design. The GB202 is expected to power the flagship GeForce RTX 5090 (or RTX 4090 successor), and if NVIDIA sticking to traditional chip design for this, then it's unlikely that smaller GPUs will be any different.

In contrast, AMD started building disaggregated devices with its current RDNA 3 generation, with its top two chips, the "Navi 31" and "Navi 32," being disaggregated chips. An interesting rumor suggests that team red's RDNA 4 generation will see a transition from disaggregated chips to multi-chip modules—packages that contain multiple fully-integrated GPU dies. Back to the green camp, and NVIDIA is expected to use an advanced 4 nm-class node for its GeForce "Blackwell" GPUs.

NVIDIA to Implement GDDR7 Memory on Top-3 "Blackwell" GPUs

NVIDIA is confirmed to implement the GDDR7 memory standard with the top three GPU ASICs powering the next-generation "Blackwell" GeForce RTX 50-series, Tweaktown reports, citing XpeaGPU. By this, we mean the top three physical silicon types from which NVIDIA will carve out the majority of its SKUs. This would include the GB202, the GB203, and GB205; which will power successors to everything from the current RTX 4070 to the RTX 4090. NVIDIA is expected to build these chips on the TSMC 4N foundry node.

There will be certain GPU ASIC types in the "Blackwell" generation that will stick to older memory standards such as GDDR6 or even the GDDR6X. These would be successors to the current AD106 and AD107 ASICs, powering SKUs such as the RTX 4060 Ti, and below. NVIDIA co-developed the GDDR6X standard with Micron Technology, which is the chip's exclusive supplier to NVIDIA. GDDR6X scales up to 23 Gbps and 16 Gbit, which means NVIDIA can avail plenty of performance for the lower-end of its product stack using GDDR6X; especially considering that its GDDR7 implementation will only run at 28 Gbps, despite chips being available in the market for 32 Gbps, or even 36 Gbps. Even if NVIDIA chooses the regular GDDR6 standard for its entry-mainstream chips, the tech scales up to 20 Gbps.

NVIDIA "Blackwell" GeForce RTX to Feature Same 5nm-based TSMC 4N Foundry Node as GB100 AI GPU

Following Monday's blockbuster announcements of the "Blackwell" architecture and NVIDIA's B100, B200, and GB200 AI GPUs, all eyes are now on its client graphics derivatives, or the GeForce RTX GPUs that implement "Blackwell" as a graphics architecture. Leading the effort will be the new GB202 ASIC, a successor to the AD102 powering the current RTX 4090. This will be NVIDIA's biggest GPU with raster graphics and ray tracing capabilities. The GB202 is rumored to be followed by the GB203 in the premium segment, the GB205 a notch lower, and the GB206 further down the stack. Kopite7kimi, a reliable source with NVIDIA leaks, says that the GB202 silicon will be built on the same TSMC 4N foundry node as the GB100.

TSMC 4N is a derivative of the company's mainline N4P node, the "N" in 4N stands for NVIDIA. This is a nodelet that TSMC designed with optimization for NVIDIA SoCs. TSMC still considers the 4N as a derivative of the 5 nm EUV node. There is very little public information on the power- and transistor density improvements of the TSMC 4N over TSMC N5. For reference, the N4P, which TSMC regards as a 5 nm derivative, offers a 6% transistor-density improvement, and a 22% power efficiency improvement. In related news, Kopite7kimi says that with "Blackwell," NVIDIA is focusing on enlarging the L1 caches of the streaming multiprocessors (SM), which suggests a design focus on increasing the performance at an SM-level.

NVIDIA Blackwell "GB203" GPU Could Sport 256-bit Memory Interface

Speculative NVIDIA GeForce RTX 50-series "GB20X" GPU memory interface details appeared online late last week—as disclosed by the kopite7kimi social media account. The inside information aficionado—at the time—posited that the "memory interface configuration of GB20x (Blackwell) is not much different from that of AD10x (Ada Lovelace)." It was inferred that Team Green's next flagship gaming GPU (GB202) could debut with a 384-bit memory bus—kopite7kimi had "fantasized" about a potentially monstrous 512-bit spec for the "GeForce RTX 5090." A new batch of follow-up tweets—from earlier today—rips apart last week's insights. The alleged Blackwell GPU gaming lineup includes the following SKUs: GB202, GB203, GB205, GB206, GB207.

Kopite7kimi's revised thoughts point to Team Green's flagship model possessing 192 streaming multiprocessors and a 512-bit memory bus. VideoCardz decided to interact with the reliable tipster—their queries were answered promptly: "According to kopite7kimi, there's a possibility that the second-in-line GPU, named GB203, could sport half of that core count. Now the new information is that GB203 might stick to 256-bit memory bus, which would make it half of GB202 in its entirety. What this also means is that there would be no GB20x GPU with 384-bit bus." Additional speculation has NVIDIA selecting a 192-bit bus for the GB205 SKU (AKA GeForce RTX 5070). The GeForce RTX 50-series is expected to arrive later this year—industry experts are already whispering about HPC-oriented Blackwell GPUs being unveiled at next week's GTC 2024 event. A formal gaming family announcement could arrive many months later.

NVIDIA Blackwell Graphics Architecture GPU Codenames Revealed, AD104 Has No Successor

The next-generation GeForce RTX 50-series graphics cards will be powered by the Blackwell graphics architecture, named after American mathematician David Blackwell. kopite7kimi, a reliable source with NVIDIA leaks revealed what the lineup of GPUs behind the series could look like. It reportedly will be led by the GB202, followed by the GB203, and then the GB205 and GB206, followed by the GB207 at the entry level. What's surprising here, is the lack of a "GB204" succeeding the AD104, GA104, TU104, and a long line of successful performance-segment GPUs by NVIDIA.

The GeForce Blackwell ASIC series begins with "GB" (GeForce Blackwell) followed by a 200-series number. The last time NVIDIA used a 200-series ASIC number for GeForce GPUs was with "Maxwell," as the GPUs ended up being built on a more advanced node, and with a few more advanced features, than what the architecture was originally conceived for. For "Blackwell," the GB202 logically succeeds the AD102, GA102, TU102, and a long line of "big chips" that have powered the company's flagship client graphics cards. The GB103 succeeds AD103, as a high SIMD count GPU with a narrower memory bus than the GB202, powering the #2 and #3 SKUs in the series. There is curiously the lack of a "GB104."
