AMD Radeon Pro Vega 64X vs AMD Radeon Pro VII Comparison

# AMD Radeon Pro VII vs AMD Radeon Pro Vega 64X

The AMD Radeon Pro VII and AMD Radeon Pro Vega 64X represent two distinct generations of AMD's professional graphics lineup, with the Pro VII built on the newer Vega 20 chip at 7 nm and the Vega 64X based on the older Vega 10 silicon at 14 nm. Across the two shared benchmark tests, the Pro VII wins decisively, but the gap varies significantly depending on the workload, with the Metal test showing a 29.9% advantage while the OpenCL test narrows to 14.9%.

Head-to-Head Benchmarks

The head-to-head comparison consists of two Geekbench tests: Metal and OpenCL. In both, the AMD Radeon Pro VII emerges as the clear winner, securing 2 wins against 0 for the Vega 64X.

The most striking result is in the geekbench_metal test, where the Pro VII scores 108,383 against the Vega 64X's 83,450. This translates to a 29.9% delta—a substantial margin that highlights the Pro VII's architectural efficiency. Metal, being Apple's low-level graphics API, tends to reward memory bandwidth and raw compute throughput, both of which favor the Pro VII's newer design.

The geekbench_opencl test tells a slightly different story. Here, the Pro VII scores 90,148 while the Vega 64X manages 78,467, resulting in a 14.9% delta. The narrower gap in OpenCL suggests that the Vega 64X's higher shading unit count (4096 vs. 3840) helps it close some of the distance, though it still cannot overcome the Pro VII's superior clock speeds and memory bandwidth.

Looking at the broader competitive landscape, the Pro VII's average benchmark score of 97,131 places it in the 93rd percentile of all GPUs, with its nearest rival being the AMD Radeon RX 7900M at 97,487 (a mere 0.4% difference). The Pro VII also sits 4.7% behind the NVIDIA Quadro RTX 6000 (101,872) and 6% ahead of the NVIDIA RTX A4500 (91,671). In contrast, the Vega 64X's average score of 80,959 puts it in the 92nd percentile, with its closest competitor being the AMD Radeon PRO W6600 at 81,995 (1.3% higher). Notably, the Vega 64X edges out the NVIDIA GeForce RTX 5090 by 1.4% (79,842) and the NVIDIA Tesla P100 PCIe 16 GB by 1.7% (79,605).

Architecture Differences

The two cards diverge fundamentally at the silicon level. The Pro VII uses the Vega 20 chip built on GCN 5.1 architecture, manufactured by TSMC at a 7 nm process node. The Vega 64X, by contrast, employs the Vega 10 chip with GCN 5.0 architecture, fabricated by GlobalFoundries at 14 nm. This process shrink is significant: the Pro VII packs 13,230 million transistors into a die size of just 331 mm², yielding a transistor density of 40.0M/mm². The Vega 64X contains 12,500 million transistors spread across a much larger 495 mm² die, resulting in a density of only 25.3M/mm²—roughly 37% lower.

Clock speeds also favor the Pro VII. Its base clock runs at 1400 MHz with a boost of 1700 MHz, compared to the Vega 64X's 1250 MHz base and 1468 MHz boost. Both cards use HBM2 memory at 1000 MHz (2 Gbps effective), but the memory configuration differs dramatically. The Pro VII features a 4096-bit bus with 16 GB of HBM2, delivering 1.02 TB/s of bandwidth. The Vega 64X uses a 2048-bit bus with the same 16 GB capacity but only achieves 512.0 GB/s—exactly half the bandwidth.

Compute resources are where the Vega 64X actually holds a nominal advantage. It packs 4096 shading units and 256 TMUs, versus the Pro VII's 3840 shading units and 240 TMUs. Both have 64 ROPs. However, the Pro VII's higher clocks and bandwidth more than compensate: its pixel rate reaches 108.8 GPixel/s versus 93.95 GPixel/s, and its texture rate hits 408.0 GTexel/s versus 375.8 GTexel/s. In raw FP32 throughput, the Pro VII delivers 13.06 TFLOPS against the Vega 64X's 12.03 TFLOPS, and FP16 performance is 26.11 TFLOPS versus 24.05 TFLOPS (both at 2:1 ratio).

Where Each One Wins

The AMD Radeon Pro VII wins every benchmark in this comparison, so the practical question is where each card excels relative to its own strengths.

The Pro VII's dominance is most pronounced in Metal workloads, where the 29.9% lead reflects its superior memory bandwidth (1.02 TB/s vs. 512.0 GB/s) and higher boost clock (1700 MHz vs. 1468 MHz). This makes it the stronger choice for macOS-based professional rendering, video editing, and GPU-accelerated compositing that leverage Metal. Its PCIe 4.0 x16 interface also doubles the bandwidth of the Vega 64X's PCIe 3.0 x16, which matters for data-heavy workloads that stream geometry or textures from system memory.

The Pro VII also wins in OpenCL, but by a narrower 14.9% margin. This suggests that the Vega 64X's higher shading unit count (4096 vs. 3840) partially offsets the Pro VII's architectural advantages in compute-heavy OpenCL tasks. Still, the Pro VII's 13.06 TFLOPS FP32 throughput and 1.02 TB/s bandwidth give it the edge in large-scale scientific computing, machine learning inference, and financial simulation workloads.

The Vega 64X, despite losing both benchmarks, is not without merit. Its 512.0 GB/s bandwidth is half the Pro VII's, yet it still achieves respectable scores—83,450 in Metal and 78,467 in OpenCL—placing it in the 92nd percentile of all GPUs. Its nearest rival, the AMD Radeon PRO W6600, scores 81,995, only 1.3% higher. The Vega 64X even outperforms the NVIDIA GeForce RTX 5090 by 1.4% and the Tesla P100 PCIe 16 GB by 1.7%, which is notable given that those are entirely different architectures. For systems where the Vega 64X is integrated (it is listed as an IGP with portable device-dependent display outputs), it offers a compelling compute solution without the need for discrete power connectors.
