AMD Radeon RX 7700S vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the AMD Radeon RX 7700S has three benchmark results in the database, while the NVIDIA N1X 40SM has no recorded benchmark scores, no average score, and no rival entries. The head-to-head benchmark array is empty. This means there are no direct comparative measurements between the two parts in our database, and the N1X 40SM cannot be positioned against the RX 7700S using any test results.

The RX 7700S posts a 3DMark Steel Nomad DX12 score of 2185, a Geekbench OpenCL score of 62983, and a Geekbench Vulkan score of 36380. Its average benchmark score across all recorded tests is 33849. The N1X 40SM has an average benchmark score of 0, which reflects the absence of any recorded test data rather than a measured performance level.

The RX 7700S sits at the 78th percentile among all GPUs in the database. Its nearest rivals are all within a narrow band: the AMD Radeon HD 7950 averages 33951, a delta of -0.3% relative to the RX 7700S; the AMD Radeon RX 480 averages 33997, a delta of -0.4%; the NVIDIA GeForce GTX 1060 5 GB averages 33694, a delta of +0.5%; and the NVIDIA RTX A5000 averages 33622, a delta of +0.7%. These deltas indicate that the RX 7700S performs essentially on par with older desktop parts, sitting within a 1% band of all four rivals. The N1X 40SM, by contrast, has no nearest rivals listed, so no comparative statement can be made from the database.

Where Each One Wins

The RX 7700S wins every category where data exists, because it is the only one with measurements. It delivers a recorded FP32 throughput of 20.48 TFLOPS against the N1X 40SM's 24.02 TFLOPS, meaning the NVIDIA part has a theoretical compute advantage of about 17% in raw FP32. However, the N1X 40SM has no benchmark results to confirm whether that theoretical figure translates into any real-world win. The RX 7700S also leads in pixel throughput at 160.0 GPixel/s versus 93.84 GPixel/s, a 70% advantage, and in memory bandwidth at 288.0 GB/s versus 273.2 GB/s, a 5.4% advantage.

The N1X 40SM shows strengths in texture throughput, delivering 750.7 GTexel/s versus the RX 7700S's 320.0 GTexel/s, a 2.35x lead. It also has more shading units (5120 versus 2048), more texture mapping units (320 versus 128), more ray tracing cores (40 versus 32), and 160 tensor cores where the RX 7700S has none. The NVIDIA part has a larger memory pool of 128 GB versus 8 GB, though its memory bandwidth is lower. None of these advantages appear in any benchmark score, so the database cannot confirm a win for the N1X 40SM in any test.

The Verdict

The data supports only one clear conclusion: the AMD Radeon RX 7700S is the only part in this comparison with measured performance. It has three benchmark scores, an average of 33849, and a 78th percentile ranking among all GPUs. The NVIDIA N1X 40SM has no benchmark results, no average score, and no rivals, so any performance claim about it cannot be verified from the database.

For users relying on recorded measurements, the RX 7700S is the only choice with evidence. Its theoretical figures place it near older desktop cards like the Radeon HD 7950 and RX 480, with deltas under 1%. The N1X 40SM offers a larger die, more shading units, more ray tracing cores, tensor cores, a larger memory pool, and higher theoretical FP32 and texture throughput, but none of that appears in any test score.

The RX 7700S also holds advantages in pixel rate, memory bandwidth, and FP16 throughput. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1X 40SM lists no API support. The RX 7700S carries a 100 W TDP and a PCIe 4.0 x16 interface. The N1X 40SM uses PCIe 5.0 x16 and has an unknown TDP.

The verdict from the database is straightforward: the RX 7700S is the only part with demonstrated performance, and the N1X 40SM cannot be evaluated without recorded benchmarks. Any selection between the two must rely on the RX 7700S's measured results, since the N1X 40SM has no data to support a comparison.
