AMD Radeon PRO W7700 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The AMD Radeon PRO W7700 has two benchmark entries in the database: a Geekbench OpenCL score of 108245 and a Geekbench Vulkan score of 129706. Its average benchmark score is 118976. The NVIDIA N1X 40SM has no recorded benchmark scores, an average benchmark score of 0, and no nearest rivals listed. This absence of data for the NVIDIA part means there is no direct head-to-head comparison to walk through with exact numbers. The database does not contain any head-to-head benchmark entries between these two products.

The AMD Radeon PRO W7700 sits at the 95th percentile among all GPUs in the database. Its nearest rivals, based on average score, include the NVIDIA GB10 with an average score of 117393 and a delta of 1.3 percent, meaning the AMD part is 1.3 percent ahead. The NVIDIA RTX 4000 SFF Ada Generation averages 117088, which places it 1.6 percent behind the W7700. The NVIDIA Tesla V100 SXM2 16 GB averages 114395, a 4 percent gap. The NVIDIA RTX A5500 Mobile averages 113944, trailing by 4.4 percent. These delta values show a modest but consistent lead for the AMD Radeon PRO W7700 over its closest competitors in average benchmark score.

The NVIDIA N1X 40SM is at the 50th percentile with no scores. The data cannot support any claim of a win for either side because the NVIDIA part produced no measurable results. The analysis must rely on the fact that the AMD part has extensive recorded performance data while the NVIDIA part has none.

Where Each One Wins

The AMD Radeon PRO W7700 wins in every category where the database has recorded measurements. Its Geekbench OpenCL score of 108245 and Vulkan score of 129706 demonstrate strong performance in both major cross-platform compute and graphics APIs. The average score of 118976 places it in the 95th percentile of all GPUs, which indicates it outperforms the vast majority of recorded hardware in the database.

The NVIDIA N1X 40SM has no recorded wins. The database lists no benchmarks, no average score, and no rival comparisons. The 50th percentile ranking is present, but without any score to anchor it, this percentile cannot be interpreted as a performance achievement. The db does not list it among any rival group, so no comparative performance claims can be made.

The use-case split is therefore entirely one-sided based on available evidence. The AMD Radeon PRO W7700 shows data supporting both compute-heavy workloads via OpenCL and graphics-oriented workloads via Vulkan. The NVIDIA part shows nothing. The 128 GB memory capacity of the NVIDIA N1X 40SM does suggest a large memory footprint use case, but no benchmark verifies how that memory performs. The AMD part has 16 GB of GDDR6 with a 256 bit bus and 576.0 GB/s bandwidth, while the NVIDIA part has 128 GB of LPDDR5X with a 256 bit bus and 273.2 GB/s bandwidth. The AMD memory bandwidth is more than double the NVIDIA figure, but memory capacity massively favors the NVIDIA part. Without benchmarks, the practical impact of that capacity cannot be quantified.

The Verdict

The data supports only one conclusion: the AMD Radeon PRO W7700 is the only product in this comparison with recorded performance. Any analysis of which GPU to select must account for the complete lack of measured results for the NVIDIA N1X 40SM. The AMD part delivers an average benchmark score of 118976, ranking in the 95th percentile. It leads its nearest rival, the NVIDIA GB10, by 1.3 percent, and the NVIDIA RTX 4000 SFF Ada Generation by 1.6 percent. These are narrow margins, but they are consistent across the four nearest rivals listed.

The NVIDIA N1X 40SM, by contrast, has a 50th percentile ranking and zero benchmark entries. The database records no average score for it. Choosing the NVIDIA part would be based on no measured performance data. The AMD Radeon PRO W7700 has a launch MSRP of 999 USD, and it was released in November 2023. The NVIDIA N1X 40SM has no launch MSRP and no release date in the database, though its production status is listed as active and its release date is listed as May 2026.

The AMD part uses the Navi 32 chip with RDNA 3.0 architecture and a 5 nm process from TSMC. It has 28,100 million transistors on a 346 mm² die. The NVIDIA part uses the GB20B chip with Blackwell 2.0 architecture, also on a 5 nm TSMC process, with a 382 mm² die. The transistor count for the NVIDIA part is unknown. The AMD part has 3072 shading units, 192 TMUs, 96 ROPs, and 48 ray tracing cores. The NVIDIA part has 5120 shading units, 320 TMUs, 40 ROPs, and 40 ray tracing cores, plus 160 tensor cores. The AMD part has no tensor cores listed.

The AMD Radeon PRO W7700 delivers 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 at a 2:1 ratio. The NVIDIA N1X 40SM delivers 24.02 TFLOPS FP32 and 24.02 TFLOPS FP16 at a 1:1 ratio. The AMD part has a higher pixel rate at 249.6 GPixel/s versus 93.84 GPixel/s, while the NVIDIA part has a higher texture rate at 750.7 GTexel/s versus 499.2 GTexel/s. The AMD part has a TDP of 190 W, while the NVIDIA TDP is unknown. The AMD part is a dual-slot card with a 1x 8-pin power connector and a suggested PSU of 450 W. The NVIDIA part is an IGP with no power connectors.

The database shows the AMD Radeon PRO W7700 is the only viable choice based on measured data. The NVIDIA N1X 40SM cannot be recommended from benchmark evidence because no benchmark evidence exists.

Architecture Differences

The AMD Radeon PRO W7700 uses the Navi 32 chip based on RDNA 3.0 architecture with the codename Wheat Nas. It belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA N1X 40SM uses the GB20B chip based on Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. Both are fabricated by TSMC on a 5 nm process, but the die sizes differ: the AMD chip is 346 mm² with 28,100 million transistors, while the NVIDIA chip is 382 mm² with an unknown transistor count. The transistor density for the AMD chip is 81.2M per mm²; no density figure exists for the NVIDIA chip.

The memory subsystems differ substantially. The AMD part uses 16 GB of GDDR6 on a 256 bit bus with 576.0 GB/s bandwidth and a memory clock of 2250 MHz, listed as 18 Gbps effective. The NVIDIA part uses 128 GB of LPDDR5X on a 256 bit bus with 273.2 GB/s bandwidth and a memory clock of 1067 MHz, listed as 8.5 Gbps effective. The AMD memory clock is higher and the bandwidth is more than double, but the NVIDIA capacity is eight times larger.

The compute configurations are built differently. The AMD part has 3072 shading units, 192 TMUs, 96 ROPs, and 48 ray tracing cores. The NVIDIA part has 5120 shading units, 320 TMUs, 40 ROPs, and 40 ray tracing cores, along with 160 tensor cores. The AMD part lists no tensor cores. The clock behavior also differs: the AMD base clock is 1900 MHz with a boost of 2600 MHz, while the NVIDIA base clock is 741 MHz with a boost of 2346 MHz. The AMD part has a much higher base clock but a relatively smaller boost gap, while the NVIDIA part has a very low base clock and a large boost range.

The rendering rates diverge. The AMD part achieves 249.6 GPixel/s pixel rate and 499.2 GTexel/s texture rate. The NVIDIA part achieves 93.84 GPixel/s pixel rate and 750.7 GTexel/s texture rate. The AMD part is ahead in pixel throughput, the NVIDIA part in texture throughput. The FP16 behavior differs as well: the AMD part delivers 63.90 TFLOPS FP16 at a 2:1 ratio, while the NVIDIA part delivers 24.02 TFLOPS FP16 at a 1:1 ratio. This means the AMD part doubles its FP32 rate for FP16, whereas the NVIDIA part does not.
