AMD Radeon PRO W7500 vs NVIDIA N1X 40SM Comparison

Where Each One Wins

The AMD Radeon PRO W7500 and the NVIDIA N1X 40SM occupy entirely separate performance domains, as the recorded data shows. The Radeon PRO W7500 is a fully benchmarked discrete workstation card with nine recorded test scores across Geekbench and Passmark suites. The NVIDIA N1X 40SM, by contrast, has no recorded benchmark scores in the database, which means its wins cannot be quantified through direct measurements. Its strengths are instead visible in architectural specifications and memory capacity.

The Radeon PRO W7500 wins on every measured test category, since it is the only one of the two with recorded scores. Its strongest results come in Geekbench Vulkan with 68634 points and Geekbench OpenCL with 58213 points. The Passmark suite shows a different distribution: DirectX 9 delivers 200 points, DirectX 11 delivers 125 points, DirectX 10 delivers 65 points, and DirectX 12 delivers 46 points. The 2D workload score is 1174, the 3D score is 13368, and the compute score is 5910. The average benchmark score for the AMD card is 16415.

The NVIDIA N1X 40SM wins in pure specification categories that favor its design. It carries 128 GB of LPDDR5X memory on a 256 bit bus, compared to 8 GB of GDDR6 on a 128 bit bus for the AMD card. It also delivers 24.02 TFLOPS FP32 performance versus 12.19 TFLOPS for the AMD card, and its texture rate of 750.7 GTexel/s is nearly four times the AMD figure of 190.4 GTexel/s. The NVIDIA card includes 160 tensor cores, while the AMD card has none listed.

The use-case split is clear from the data. The Radeon PRO W7500 is a tested, active discrete GPU with a 59th percentile rank against all GPUs, a single-slot form factor, and a 70 W TDP. The NVIDIA N1X 40SM is an integrated graphics processor with a 50th percentile rank, no benchmark scores, and a 2026 release date. For any workload where measured results matter, the AMD card wins by default. For workloads requiring massive memory capacity or tensor core acceleration, the NVIDIA part is the only option with those features.

Architecture Differences

The two chips are built on different process nodes and architectures. The AMD Radeon PRO W7500 uses the Navi 33 chip on the RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Radeon Pro Navi (Navi III Series) generation. It is fabricated on a 6 nm process at TSMC with 13300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². The NVIDIA N1X 40SM uses the GB20B chip on the Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. It is fabricated on a 5 nm process at TSMC with a 382 mm² die size; its transistor count is listed as unknown.

Clock behavior differs substantially. The AMD card has a base clock of 1500 MHz and a boost clock of 1700 MHz. The NVIDIA part has a much lower base clock of 741 MHz but a much higher boost clock of 2346 MHz. This wide boost range suggests a power-managed integrated design. Memory clocks also differ: the AMD card runs memory at 2000 MHz with 16 Gbps effective, while the NVIDIA part runs at 1067 MHz with 8.5 Gbps effective.

Compute unit organization shows a stark contrast. The AMD card has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The NVIDIA card has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The NVIDIA part has nearly three times the shading units and nearly three times the TMUs, but fewer ROPs. The AMD card has no tensor cores listed, while the NVIDIA card has 160, a decisive difference for AI-oriented workloads.

Memory subsystems are fundamentally different. The AMD card uses 8 GB of GDDR6 with 256.0 GB/s of bandwidth. The NVIDIA card uses 128 GB of LPDDR5X with 273.2 GB/s of bandwidth. The NVIDIA memory pool is 16 times larger and provides slightly higher bandwidth despite the lower clock, thanks to the 256 bit bus versus 128 bit.

Form factor and power handling separate the two clearly. The AMD card is a single-slot, 216 mm long, 115 mm tall, 20 mm wide add-in board with no power connectors and a suggested PSU of 250 W. Its TDP is 70 W. The NVIDIA part is an IGP with no dimensions listed, no power connectors, and an unknown TDP. The AMD card uses PCIe 4.0 x8 while the NVIDIA part uses PCIe 5.0 x16. Display outputs also differ: the AMD card has 4x DisplayPort 2.1, while the NVIDIA part has a single HDMI output.

API support separates them further. The AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan in the database. The AMD card has active production status with a release date of 2023-08-02, while the NVIDIA part also has active production status but a release date of 2026-05-31.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two products. The Radeon PRO W7500 has nine recorded benchmark scores and a computed average of 16415, while the NVIDIA N1X 40SM has zero recorded scores and an average of 0. This absence of NVIDIA measurements means the only numerical comparisons possible are between the AMD card's scores and its own nearest rivals, plus specification-level contrasts with the NVIDIA part.

The AMD card's nearest rival by average score is the NVIDIA RTX PRO 6000 Blackwell at 16408, a delta of 0 percent. The AMD Radeon RX 5700 XT scores 16361, which is 0.3 percent behind the W7500. The AMD Radeon Pro 5600M scores 16351, 0.4 percent behind. The NVIDIA GeForce RTX 5090 D V2 scores 16504, which is 0.5 percent ahead of the W7500. These deltas show the W7500 sits in a very tight cluster around the 16400 average score mark, within half a percent of four other GPUs.

Within its own benchmark suite, the Radeon PRO W7500 shows clear internal rankings. The Geekbench Vulkan score of 68634 is the highest single result, and the Geekbench OpenCL score of 58213 is second. The Passmark G3D score of 13368 is the third highest. The Passmark G2D score of 1174 and the compute score of 5910 round out the mid-range. The DirectX legacy tests are far lower: DirectX 9 at 200, DirectX 11 at 125, DirectX 10 at 65, and DirectX 12 at 46.

The specification comparison between the two cards shows the NVIDIA part leading in raw compute throughput. Its FP32 figure of 24.02 TFLOPS is 97 percent higher than the AMD card's 12.19 TFLOPS. Its FP16 figure of 24.02 TFLOPS is effectively identical to its FP32 figure, indicating a 1:1 ratio, whereas the AMD card achieves 24.37 TFLOPS FP16 at a 2:1 ratio. The NVIDIA texture rate of 750.7 GTexel/s is 294 percent higher than the AMD rate of 190.4 GTexel/s. The AMD pixel rate of 108.8 GPixel/s is slightly higher than the NVIDIA figure of 93.84 GPixel/s, a 16 percent advantage. The AMD card's 64 ROPs versus 40 ROPs explains this pixel rate edge.

Memory bandwidth favors the NVIDIA part modestly: 273.2 GB/s versus 256.0 GB/s, a 6.7 percent advantage. Memory capacity favors it enormously: 128 GB versus 8 GB, a 16x difference. The NVIDIA card's 5120 shading units versus 1792 gives it a 2.86x unit advantage. Its 320 TMUs versus 112 gives a 2.86x texture unit advantage. Its 40 RT cores versus 28 gives a 1.43x ray tracing advantage.

The Verdict

The data describes two products with almost no overlap in purpose. The AMD Radeon PRO W7500 is a measured, active discrete workstation card with a 70 W TDP, a single-slot design, and a 59th percentile standing. Its average score of 16415 places it within 0.5 percent of several well-known GPUs, including the NVIDIA RTX PRO 6000 Blackwell and the AMD Radeon RX 5700 XT. It delivers verified DirectX, OpenGL, and Vulkan support, plus four DisplayPort 2.1 outputs.

The NVIDIA N1X 40SM is an integrated graphics processor with no measured scores and a 50th percentile rank. Its strengths are architectural: 128 GB of memory, 5120 shading units, 160 tensor cores, and 24.02 TFLOPS FP32. But none of that is validated by benchmark results in the database.

For applications where tested performance, driver-validated API support, and a compact discrete form factor matter, the Radeon PRO W7500 is the only option with supporting data. For applications requiring massive memory capacity, tensor core acceleration, or the higher raw FP32 throughput of the NVIDIA design, the N1X 40SM is the only option with those specifications. The choice rests entirely on whether measured results or specification headroom carry more weight for the intended workload.
