AMD Radeon PRO W7800 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data does not include any direct head-to-head benchmark results between the AMD Radeon PRO W7800 and the NVIDIA N1X 40SM. There are no shared test entries, no win counts for either product, and no comparative scores in the database. This absence of direct measurement data makes a conventional benchmark comparison impossible. However, the database does contain independent benchmark results for the AMD Radeon PRO W7800, along with its percentile ranking and nearest rival scores, which provide a reference point for assessing its performance class. The NVIDIA N1X 40SM has no benchmark entries at all, with an average benchmark score of zero and a percentile rank of 50 among all GPUs. That percentile value is present in the database, but it carries little interpretive weight without supporting test scores.

For the AMD Radeon PRO W7800, the database records a Geekbench OpenCL score of 154366 and a Geekbench Vulkan score of 175422. Its average benchmark score across recorded tests is 164894. The W7800 sits at the 97th percentile of all GPUs in the database, indicating that it outperforms the vast majority of recorded graphics hardware. Its nearest rivals in the database include the NVIDIA RTX A5500 with an average score of 165217 and a delta of -0.2 percent relative to the W7800, meaning the A5500 is essentially tied with the W7800, ahead by a negligible margin. The NVIDIA RTX 4500 Ada Generation scores 166094, a delta of -0.7 percent, again a near tie. The NVIDIA A100 PCIe 40 GB scores 162504, which is 1.5 percent behind the W7800. The AMD Radeon Pro W6900X scores 168574, placing it 2.2 percent ahead of the W7800. These figures show that the W7800 operates within a tightly clustered performance band, with all four nearest rivals within roughly two points of its average score.

The NVIDIA N1X 40SM lacks any comparable benchmark data. Its average score is recorded as zero, and there are no nearest rivals listed. The database does not provide any way to infer its compute performance relative to the W7800. The only numeric performance indicators available are architectural: its FP32 throughput is listed at 24.02 TFLOPS, its texture rate at 750.7 GTexel/s, and its pixel rate at 93.84 GPixel/s. The W7800, by comparison, shows an FP32 figure of 45.25 TFLOPS, a texture rate of 707.0 GTexel/s, and a pixel rate of 323.2 GPixel/s. These are theoretical peak rates, not measured application scores, but they indicate that the W7800 has a substantially higher FP32 compute ceiling and pixel throughput, while the N1X 40SM has a slightly higher texture fill rate. The W7800 also records an FP16 rate of 90.50 TFLOPS with a 2:1 ratio, whereas the N1X 40SM lists 24.02 TFLOPS FP16 at a 1:1 ratio. None of these figures substitute for actual head-to-head test data, which the database does not contain.

Architecture Differences

The two products come from different manufacturers and use different underlying architectures. The AMD Radeon PRO W7800 uses the Navi 31 chip with the RDNA 3.0 architecture, under the codename Plum Bonito. It is part of the Radeon Pro Navi generation, specifically the Navi III Series. The NVIDIA N1X 40SM uses the GB20B chip with the Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. Both are fabricated on a 5 nm process at TSMC, but their transistor counts differ dramatically. The W7800 contains 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1 million per square millimeter. The N1X 40SM has an unknown transistor count on a 382 mm² die, and its transistor density is not recorded.

Memory configurations also diverge sharply. The W7800 uses 32 GB of GDDR6 memory on a 256 bit bus, with a bandwidth of 576.0 GB/s and a memory clock listed at 2250 MHz, or 18 Gbps effective. The N1X 40SM uses 128 GB of LPDDR5X memory, also on a 256 bit bus, but its bandwidth is much lower at 273.2 GB/s, with a memory clock of 1067 MHz, or 8.5 Gbps effective. The N1X 40SM has four times the memory capacity but less than half the bandwidth. The W7800 has 4480 shading units, 280 texture mapping units, and 128 raster operation pipelines. It also includes 70 ray tracing cores. The N1X 40SM has 5120 shading units, 320 TMUs, and only 40 ROPs, along with 40 ray tracing cores and 160 tensor cores. The W7800 has no tensor cores recorded. The N1X 40SM's ROP count is notably low relative to its shading unit count, which aligns with its lower pixel rate.

Clock behavior differs as well. The W7800 runs at a base clock of 1895 MHz and a boost clock of 2525 MHz. The N1X 40SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz. The power and physical specifications point to different intended use cases. The W7800 has a TDP of 260 W, requires two 8-pin power connectors, and a suggested power supply of 600 W. It is a dual-slot card measuring 280 mm in length, 110 mm in height, and 40 mm in width. The N1X 40SM has an unknown TDP, no power connectors, and is classified as an IGP, meaning an integrated graphics processor. Its dimensions are not recorded. The N1X 40SM uses a PCIe 5.0 x16 interface, while the W7800 uses PCIe 4.0 x16.

API support also separates the two. The W7800 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. Display outputs differ: the W7800 provides three DisplayPort 2.1 outputs and one mini-DisplayPort 2.1 output, while the N1X 40SM provides a single HDMI output. The W7800 was released on April 12, 2023, with a launch MSRP of 2,499 USD. The N1X 40SM has a release date of May 31, 2026, and no recorded launch MSRP.

The Verdict

The data supports a clear conclusion for most professional workloads: the AMD Radeon PRO W7800 is the higher-performance discrete workstation part. Its measured benchmark scores place it at the 97th percentile of all GPUs, with an average score of 164894. Its nearest rivals are all within roughly two percent of its average score, which confirms that it competes at the top tier of recorded workstation GPUs. Its FP32 throughput of 45.25 TFLOPS is nearly double the 24.02 TFLOPS of the NVIDIA N1X 40SM. Its pixel rate of 323.2 GPixel/s is more than three times the N1X 40SM's 93.84 GPixel/s. Its memory bandwidth of 576.0 GB/s is more than double the N1X 40SM's 273.2 GB/s. Its ray tracing core count of 70 exceeds the N1X 40SM's 40. On every compute-oriented metric recorded in the database, the W7800 leads.

The NVIDIA N1X 40SM, however, has advantages that matter in specific contexts. It has 128 GB of memory, four times the W7800's 32 GB. It has 160 tensor cores, which the W7800 lacks entirely. It has 5120 shading units and 320 TMUs, both higher than the W7800's 4480 and 280. Its texture rate of 750.7 GTexel/s is slightly higher than the W7800's 707.0 GTexel/s. Its PCIe 5.0 interface is a generation newer than the W7800's PCIe 4.0. These figures suggest the N1X 40SM is built for a different purpose, likely an integrated solution for large-memory or tensor-heavy workloads, rather than a direct competitor to a discrete workstation card. The absence of any benchmark scores for the N1X 40SM means its real-world performance cannot be verified from the database, so any conclusion about its speed must remain provisional. The W7800 is the only one of the two with recorded measurements, and those measurements are strong.
