AMD Radeon PRO W7600 vs NVIDIA N1 20SM Comparison

The Verdict

The AMD Radeon PRO W7600 is the only one of these two parts with recorded benchmark data in the database. It posts an average benchmark score of 87108, placing it in the 93rd percentile of all GPUs. The NVIDIA N1 20SM, by contrast, has no benchmark entries, an average score of 0, and sits at the 50th percentile. For anyone selecting a GPU for measured compute or graphics workloads, the Radeon PRO W7600 is the choice backed by data.

The N1 20SM is an integrated graphics processor (IGP) with a different purpose. It carries 128 GB of LPDDR5X memory and 80 tensor cores, which suggests a focus on memory capacity and AI-related tasks rather than raw rasterization. The Radeon PRO W7600 is a discrete, single-slot, actively produced workstation card with a 599 USD launch MSRP. The data indicates the Radeon PRO W7600 for standard GPU benchmarks; the N1 20SM has no measurable score to compare.

The N1 20SM has no benchmarks listed at all. Its average score is recorded as 0, and its percentile rank is 50, which appears to be a default or placeholder value rather than a measured result. The Radeon PRO W7600's 93rd percentile placement is a clear separation. With an average score of 87108, the Radeon PRO W7600 sits close to several NVIDIA workstation parts in the database. The NVIDIA Quadro GP100 averages 87445, which is 0.4% higher. The NVIDIA RTX A4500 Mobile averages 91134, putting it 4.4% above the Radeon. The NVIDIA RTX A4500 averages 91671, 5% higher. The only rival the Radeon PRO W7600 beats in this group is the NVIDIA CMP 40HX, which averages 85637, a 1.7% deficit.

The Radeon PRO W7600's texture rate is 312.3 GTexel/s, while its pixel rate is 156.2 GPixel/s. It delivers 19.99 TFLOPS FP32 and 39.98 TFLOPS FP16 (2:1 ratio). The N1 20SM has a higher texture rate at 375.4 GTexel/s but a much lower pixel rate at 56.30 GPixel/s. Its FP32 throughput is 12.01 TFLOPS, and its FP16 is 12.01 TFLOPS (1:1 ratio). The Radeon PRO W7600 leads in pixel fill and FP32 compute, while the N1 20SM leads in texture fill. The Radeon PRO W7600 also has higher memory bandwidth at 288.0 GB/s versus 273.2 GB/s, despite the N1 20SM's wider 256-bit bus and much larger 128 GB capacity.
