AMD Radeon Pro Vega 64X vs AMD Radeon RX 7600M Comparison

The Verdict

The recorded benchmark data splits these two AMD parts cleanly by workload. The AMD Radeon Pro Vega 64X leads in raw compute throughput, posting an average benchmark score of 80,959 against 63,775 for the AMD Radeon RX 7600M. In the single head-to-head test available, Geekbench OpenCL, the Vega 64X wins by 23%. That margin is substantial and places the older workstation part in a higher performance tier overall, with a 92nd percentile ranking among all GPUs versus 89th for the RX 7600M.

However, the RX 7600M is not simply a slower duplicate. It is a modern, power-efficient mobile chip built on a 6 nm process, while the Vega 64X is a 14 nm integrated graphics processor from 2019 that has reached end-of-life. The RX 7600M also brings hardware ray tracing cores, which the Vega 64X lacks entirely. For users who need maximum compute throughput in OpenCL-style workloads and can tolerate a 250 W power envelope, the Vega 64X is the stronger pick. For anyone constrained by thermals or battery life, or who wants modern feature support such as DirectX 12 Ultimate and Vulkan 1.4, the RX 7600M is the practical choice.

Architecture Differences

The two GPUs represent opposite ends of AMD's design philosophy. The Radeon Pro Vega 64X uses the Vega 10 chip on the GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 12,500 million transistors onto a 495 mm² die, yielding a transistor density of 25.3 million per square millimeter. The RX 7600M, by contrast, uses the Navi 33 chip on the RDNA 3.0 architecture, built on a 6 nm process at TSMC. It houses 13,300 million transistors but on a much smaller 204 mm² die, giving a density of 65.2 million per square millimeter. The newer process allows the RX 7600M to fit more transistors into less space and run at higher clocks.

The Vega 64X has a much wider compute layout: 4096 shading units, 256 texture mapping units, and 64 ROPs. The RX 7600M has 1792 shading units, 112 TMUs, and 64 ROPs. Yet the RX 7600M reaches higher pixel rates, 154.2 GPixel/s versus 93.95 GPixel/s, thanks to its boost clock of 2410 MHz against the Vega 64X's 1468 MHz. In floating-point, the RX 7600M actually wins on paper: 17.27 TFLOPS FP32 versus 12.03 TFLOPS for the Vega 64X, and 34.55 TFLOPS FP16 versus 24.05 TFLOPS. The Vega 64X counters with higher texture throughput, 375.8 GTexel/s versus 269.9 GTexel/s, due to its larger TMU count.

Memory architecture differs sharply. The Vega 64X uses 16 GB of HBM2 on a 2048-bit bus, delivering 512.0 GB/s of bandwidth. The RX 7600M uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s. That is exactly half the bandwidth, which explains why the Vega 64X excels in memory-heavy compute tasks. The RX 7600M has 28 ray tracing cores, while the Vega 64X has none, marking a generational feature gap.

Head-to-Head Benchmarks

The database contains one direct comparison between these two GPUs, and it goes decisively to the Vega 64X. In Geekbench OpenCL, the Vega 64X records 78,467 points against 63,775 for the RX 7600M, a 23% advantage. That result aligns with the Vega 64X's overall standing: its average score of 80,959 sits 1.4% above the NVIDIA GeForce RTX 5090's 79,842 and 1.7% above the NVIDIA Tesla P100 PCIe 16 GB's 79,605. The Vega 64X also edges out the AMD Radeon PRO W6600, which scores 81,995, by a marginal 1.3% in the other direction. In percentile terms, the Vega 64X ranks in the 92nd percentile of all GPUs, while the RX 7600M ranks in the 89th.

The RX 7600M's nearest rivals show a tighter cluster. Its average of 63,775 is within 0.1% of the AMD Radeon RX 9060 XT LP (63,830) and the NVIDIA CMP 30HX (63,842), and within 0.7% of the AMD Radeon Pro WX 9100 (64,212). It leads the AMD Radeon Pro Vega 56 by 0.1%, a narrow margin that underscores how close the midrange mobile part sits to older workstation silicon. The Vega 64X, by contrast, competes at a level roughly 27% higher than the RX 7600M's average, a gap that no single benchmark in this comparison narrows.

The open question is why the RX 7600M's higher FP32 and FP16 figures do not translate to a win in the recorded OpenCL test. The answer likely lies in memory: the Vega 64X's 512.0 GB/s of bandwidth is double the RX 7600M's 256.0 GB/s, and its 16 GB of HBM2 capacity is double the 8 GB of GDDR6. Compute-heavy OpenCL workloads often scale with memory throughput, and the Vega 64X's 2048-bit bus provides an enormous advantage. The RX 7600M counters with a higher pixel rate, 154.2 GPixel/s versus 93.95 GPixel/s, and a higher texture rate per shading unit, but that does not offset the memory deficit in this particular test.

The architectural split also matters. The Vega 64X uses a 14 nm process and draws 250 W, while the RX 7600M uses 6 nm and draws 90 W. The newer chip achieves its clock advantage, 2410 MHz boost versus 1468 MHz, with less than half the power draw. It also supports PCIe 4.0 x16 against PCIe 3.0 x16, and DirectX 12 Ultimate against DirectX 12_1. For gaming, the RX 7600M's ray tracing cores and higher clocks likely matter more than raw compute, though no gaming benchmark appears in this dataset. The recorded data only shows OpenCL, and there, the older Vega 64X remains the clear winner.
