AMD Radeon PRO W7900 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the AMD Radeon PRO W7900, while the NVIDIA N1X 40SM has no benchmark entries. This creates an asymmetric comparison: the AMD part has measurable performance data, and the NVIDIA part does not. The AMD Radeon PRO W7900 delivers an average benchmark score of 110,725 across its two recorded tests, placing it in the 94th percentile against all GPUs in the database. The NVIDIA N1X 40SM sits in the 50th percentile with an average benchmark score of zero, indicating no completed tests have been logged for this part.

Looking at the AMD Radeon PRO W7900's individual benchmark results, the OpenCL score reaches 84,379, while the Vulkan score climbs to 137,070. The Vulkan result is considerably higher than the OpenCL result, showing a 62.4% advantage within the same hardware. The average of these two scores, 110,725, represents the midpoint between them. The NVIDIA N1X 40SM cannot be compared on these same tests because no Vulkan or OpenCL scores exist in the database for that part.

The nearest rival data for the AMD Radeon PRO W7900 provides additional context. The AMD Radeon Pro Vega II averages 109,617, which is 1% below the W7900's average. The NVIDIA RTX A5500 Mobile averages 113,944, which is 2.8% higher than the W7900. The AMD Radeon Pro W6600X averages 107,342, sitting 3.2% lower. The NVIDIA Tesla V100 SXM2 16 GB averages 114,395, which is 3.2% higher than the W7900. These four rivals bracket the W7900's performance closely, with the W7900 landing between them rather than clearly ahead of or behind the group.

The NVIDIA N1X 40SM has no nearest rivals listed in the database, and therefore no delta percentages or comparative scores can be cited. The data shows that the W7900 holds a measurable performance position among its peers, while the N1X 40SM remains unquantified in the benchmark database.

Where Each One Wins

The AMD Radeon PRO W7900 wins in compute performance based on the recorded data. Its FP32 throughput is 61.32 TFLOPS, and its FP16 throughput matches at 61.32 TFLOPS with a 1:1 ratio. The NVIDIA N1X 40SM delivers 24.02 TFLOPS in FP32 and the same 24.02 TFLOPS in FP16, also at a 1:1 ratio. This means the AMD part provides roughly 2.55 times the raw floating-point throughput in both precisions. The W7900's pixel rate reaches 479.0 GPixel/s, while the N1X 40SM manages 93.84 GPixel/s, a 5.1 times difference. Texture rate favors the W7900 as well: 958.1 GTexel/s versus 750.7 GTexel/s, a 27.6% advantage.

Memory capacity and bandwidth split the two parts in opposite directions. The NVIDIA N1X 40SM carries 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The AMD Radeon PRO W7900 has 48 GB of GDDR6 memory on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The AMD part offers 3.16 times the memory bandwidth, while the NVIDIA part offers 2.67 times the memory capacity. For workloads that require holding very large datasets locally, the N1X 40SM's 128 GB capacity is the decisive factor. For workloads that stream data quickly, the W7900's 864.0 GB/s bandwidth wins.

In ray tracing, the AMD Radeon PRO W7900 has 96 RT cores, while the NVIDIA N1X 40SM has 40 RT cores. The NVIDIA part includes 160 tensor cores, which the AMD part lacks entirely. The NVIDIA part also uses a PCIe 5.0 x16 bus interface, while the AMD part uses PCIe 4.0 x16. Display outputs differ as well: the AMD part provides 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, while the NVIDIA part provides a single HDMI output.

Architecture Differences

The AMD Radeon PRO W7900 is built on the Navi 31 chip using the RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA N1X 40SM uses the GB20B chip with the Blackwell 2.0 architecture and falls into the Blackwell IGP (N1x) generation. Both parts are manufactured by TSMC on a 5 nm process node.

The AMD chip contains 57,700 million transistors on a die size of 529 mm², yielding a transistor density of 109.1M per mm². The NVIDIA chip's transistor count is listed as unknown, but its die size is 382 mm², which is 27.8% smaller than the AMD die. The NVIDIA chip has no recorded transistor density figure.

The AMD Radeon PRO W7900 has 6,144 shading units, 384 texture mapping units, and 192 raster output units. The NVIDIA N1X 40SM has 5,120 shading units, 320 TMUs, and 40 ROPs. The AMD part has 20% more shading units, 20% more TMUs, and 4.8 times more ROPs. The NVIDIA part counters with 160 tensor cores, a feature entirely absent from the AMD specification.

Clock speeds favor the AMD part. The base clock is 1760 MHz versus 741 MHz for the NVIDIA part, and the boost clock is 2495 MHz versus 2346 MHz. The AMD base clock is 2.37 times higher, while the boost clock is 6.4% higher. The memory clocks also differ: the AMD memory runs at 2250 MHz with 18 Gbps effective, while the NVIDIA memory runs at 1067 MHz with 8.5 Gbps effective.

The AMD Radeon PRO W7900 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan, which indicates no API support data has been recorded. This is consistent with its IGP (integrated graphics processor) slot width classification, whereas the AMD part is a triple-slot discrete card.

Power delivery differs substantially. The AMD part has a TDP of 295 W, uses two 8-pin power connectors, and suggests a 600 W power supply. The NVIDIA part has an unknown TDP, no power connectors, and no suggested power supply rating. The AMD card measures 280 mm in length, 110 mm in height, and 51 mm in width. The NVIDIA part has no recorded dimensions, consistent with its IGP form factor.

The AMD Radeon PRO W7900 was released on 2023-05-25, with a predecessor in the Radeon Pro Vega line. The NVIDIA N1X 40SM has a release date of 2026-05-31 and no predecessor on record. The AMD part has a launch MSRP of 3,999 USD, while the NVIDIA part has no launch MSRP recorded.

The Verdict

The database shows two GPUs with fundamentally different positioning. The AMD Radeon PRO W7900 is a fully specified discrete workstation card with measured performance data, a 94th percentile ranking, and a clear set of nearest rivals. The NVIDIA N1X 40SM is an IGP-class part with no benchmark scores, no API support records, and no comparative data against other GPUs.

For compute-heavy rendering or simulation workloads that rely on raw floating-point throughput, the AMD Radeon PRO W7900 is the clear choice from the recorded data. Its 61.32 TFLOPS FP32 output, 864.0 GB/s memory bandwidth, and 479.0 GPixel/s pixel rate all exceed the NVIDIA part by wide margins. The AMD part also has 96 RT cores versus 40, and 192 ROPs versus 40, which supports higher fill-rate workloads.

For workloads that require very large memory capacity, the NVIDIA N1X 40SM holds the advantage with 128 GB versus 48 GB. This makes it suitable for datasets that exceed the AMD part's capacity, although its 273.2 GB/s bandwidth is less than one third of the AMD part's throughput. The NVIDIA part also brings 160 tensor cores and a PCIe 5.0 x16 interface, which may matter for applications that use tensor operations or need newer bus connectivity.

The AMD Radeon PRO W7900 has a launch MSRP of 3,999 USD and requires a 295 W TDP with two 8-pin connectors and a 600 W suggested power supply. The NVIDIA N1X 40SM has no power connectors and no power supply recommendation, making it a lower-integration part by design. The AMD card occupies a triple-slot form factor at 280 mm length, while the NVIDIA part is classified as an IGP.

The recorded data supports selecting the AMD Radeon PRO W7900 when maximum compute throughput, memory bandwidth, and display connectivity are required. The NVIDIA N1X 40SM is the only option when memory capacity above 48 GB or tensor core functionality is essential, though its lack of benchmark data means its actual performance cannot be verified from the database.
