NVIDIA GB10 vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the NVIDIA GB10 and the NVIDIA GeForce RTX 5080 SUPER. Each product was tested against entirely different benchmark suites, which makes a direct score comparison impossible. The GB10 was evaluated with Geekbench OpenCL and Vulkan tests, producing an average benchmark score of 117,393, while the RTX 5080 SUPER was evaluated with a single 3DMark Steel Nomad DX12 test, yielding an average benchmark score of 3,075.

The GB10 sits at the 95th percentile among all GPUs in the database, meaning it outperforms the vast majority of recorded graphics processors. Its nearest rivals include the AMD Radeon PRO W7700 with an average score of 118,976, which is 1.3% ahead of the GB10, and the NVIDIA RTX 4000 SFF Ada Generation with 117,088, which is only 0.3% behind. The NVIDIA Tesla V100 SXM2 16 GB trails by 2.6%, and the NVIDIA RTX A5500 Mobile trails by 3%. These tight deltas indicate the GB10 sits in a highly competitive performance cluster where small percentage differences separate adjacent products.

The RTX 5080 SUPER, by contrast, ranks at the 19th percentile in the database, a much lower standing. Its nearest rivals are the Intel Arc Pro B60 with an average score of 3,182, which is 3.4% ahead, and the NVIDIA Quadro P1000 with 3,163, which is 2.8% ahead. The NVIDIA GeForce 820A trails by 3.1%, and the NVIDIA GeForce GTX 860M trails by 3.6%. The RTX 5080 SUPER's single benchmark score places it among much older and less powerful GPUs in the database ranking, which reflects the nature of the test used rather than the raw capability of the hardware itself.

The absence of shared benchmarks between these two products means the database cannot produce a direct win count for either side. The winsA and winsB fields both record zero. What the data does show is that the GB10 delivers substantially higher computational throughput in its tested workloads, with an FP32 rating of 29.71 TFLOPS versus 56.28 TFLOPS for the RTX 5080 SUPER. The RTX 5080 SUPER more than doubles the GB10's FP32 performance, yet its benchmark percentile is far lower because the 3DMark Steel Nomad test measures different aspects of GPU behavior, particularly modern DirectX 12 rendering workloads that the GB10 does not support at all.

Architecture Differences

Both processors use the NVIDIA Blackwell 2.0 architecture and are fabricated on a 5 nm process at TSMC. This shared foundation means the fundamental microarchitecture, instruction set, and feature generation are identical. The differences emerge in chip design, configuration, and intended usage.

The GB10 uses the GB20B chip with a die size of 382 mm², while the RTX 5080 SUPER uses the GB203 chip with a die size of 378 mm². The transistor count for the GB10 is listed as unknown in the database, whereas the RTX 5080 SUPER contains 45,600 million transistors with a density of 120.6 million per square millimeter. The GB10's die is slightly larger despite having fewer shading units, which suggests a different layout priority, likely favoring memory capacity and server-oriented features.

The GB10 is classified under the Server Blackwell (Bxx) generation, with its predecessor listed as Server Hopper and its successor as Server Rubin. It carries 6,144 shading units, 384 texture mapping units, 48 raster output units, 48 ray tracing cores, and 384 tensor cores. The RTX 5080 SUPER belongs to the GeForce 50-series generation, with no predecessor or successor recorded. It contains 10,752 shading units, 336 texture mapping units, 112 raster output units, 84 ray tracing cores, and 336 tensor cores. The RTX 5080 SUPER has 75% more shading units and 75% more ray tracing cores than the GB10, but fewer texture mapping units and tensor cores.

The GB10's API support is entirely absent: DirectX, OpenGL, and Vulkan are all listed as N/A. The RTX 5080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This is a critical architectural distinction. The GB10 is not designed for conventional graphics API workloads, while the RTX 5080 SUPER fully supports modern graphics standards, including ray tracing and mesh shaders through DirectX 12 Ultimate.

Clock speeds also differ significantly. The GB10 runs at a base clock of 1665 MHz and a boost clock of 2418 MHz. The RTX 5080 SUPER runs at a base clock of 2295 MHz and a boost clock of 2617 MHz. The RTX 5080 SUPER's boost clock is 199 MHz higher, contributing to its higher compute throughput. Memory architecture diverges sharply as well: the GB10 uses 128 GB of LPDDR5X memory on a 256-bit bus, achieving 273.2 GB/s of bandwidth, while the RTX 5080 SUPER uses 24 GB of GDDR7 memory on the same 256-bit bus, achieving 1.02 TB/s of bandwidth. The RTX 5080 SUPER delivers 3.7 times the memory bandwidth of the GB10, despite having far less capacity.

Power characteristics reveal the intended deployment. The GB10 has a TDP of 140 W, uses an integrated graphics processor (IGP) slot width, requires no power connectors, and suggests a 300 W power supply. The RTX 5080 SUPER has a TDP of 415 W, uses a dual-slot form factor, requires a single 16-pin power connector, and has no suggested power supply listed. The physical dimensions tell the same story: the GB10 measures 150 mm by 51 mm by 150 mm, while the RTX 5080 SUPER measures 304 mm by 137 mm by 40 mm. The GB10 is a compact integrated solution, whereas the RTX 5080 SUPER is a large discrete expansion card.

The Verdict

The data indicates that these two GPUs serve entirely different purposes despite sharing an architecture name. The GB10 is a server-oriented processor with an integrated form factor, zero conventional graphics API support, and a massive 128 GB memory pool. The RTX 5080 SUPER is a consumer gaming and workstation card with full DirectX 12 Ultimate support, a 24 GB GDDR7 frame buffer, and more than double the FP32 compute throughput.

Users who require server acceleration, large memory capacity for data-intensive workloads, and a compact integrated design should select the GB10. Its 128 GB of LPDDR5X memory and 95th percentile benchmark standing demonstrate strength in compute-heavy, non-graphics applications. The GB10's 140 W TDP and lack of external power connectors make it suitable for systems where power density and physical space are constrained.

Users who require modern graphics rendering, gaming performance, or DirectX 12 workloads should select the RTX 5080 SUPER. Its 56.28 TFLOPS FP32 performance, 1.02 TB/s memory bandwidth, and full API support make it the clear choice for conventional graphics pipelines. The RTX 5080 SUPER's 84 ray tracing cores and 112 raster output units provide hardware acceleration for contemporary rendering techniques that the GB10 cannot execute through standard graphics APIs.

The RTX 5080 SUPER's low 19th percentile ranking does not reflect poorly on its hardware; it reflects the limited benchmark data available. The single 3DMark Steel Nomad score is not comparable to the Geekbench results recorded for the GB10. The architectural specifications, however, show the RTX 5080 SUPER delivering nearly double the FP32 throughput, 3.7 times the memory bandwidth, and full graphics API support. The GB10 counters with 5.3 times the memory capacity, a lower power draw, and a much smaller physical footprint.
