AMD Radeon Pro Vega 64 vs AMD Radeon Pro VII Comparison

The AMD Radeon Pro VII and AMD Radeon Pro Vega 64 are both end-of-life professional workstation GPUs from AMD, but they represent two distinctly different generations of the Vega architecture. The data shows a clear performance hierarchy: the Pro VII wins all three head-to-head benchmark comparisons, with its largest advantage in Geekbench Metal where it scores 108,383 against the Vega 64’s 71,868, a 50.8% delta. However, the Pro Vega 64 holds its own in raw compute resources with more shading units (4,096 vs 3,840), yet falls behind in nearly every measurable performance metric. This comparison is less about a close contest and more about understanding how architectural evolution—specifically the shift from 14nm to 7nm—translates into tangible benchmark gains, while also acknowledging that the Pro Vega 64 was designed for a unique form factor (IGP for portable devices) that the Pro VII does not offer.

The Verdict

For users prioritizing raw compute performance in professional applications, the AMD Radeon Pro VII is the unequivocal choice based on benchmark data. It leads in every single head-to-head test: Geekbench Metal (108,383 vs 71,868), Geekbench OpenCL (90,148 vs 71,094), and Geekbench Vulkan (92,862 vs 74,174). The smallest margin of victory is 25.2% in Vulkan, which is a substantial lead. The Pro VII’s average benchmark score of 97,131 places it in the 93rd percentile of all GPUs, while the Pro Vega 64’s average of 72,379 sits in the 91st percentile. In terms of nearest rivals, the Pro VII is 5% ahead of the AMD Radeon Instinct MI60 and 6% ahead of the NVIDIA RTX A4500, while trailing the NVIDIA Quadro RTX 6000 by 4.7%. The Pro Vega 64, by contrast, is nearly tied with the NVIDIA TITAN X Pascal (0.4% faster) and the AMD Radeon RX 6650M (0.9% faster).

The Pro Vega 64, however, is not without a niche. Its status as an IGP (integrated graphics processor) with "Portable Device Dependent" display outputs and no power connectors makes it uniquely suited for mobile or all-in-one workstation implementations where the Pro VII’s dual-slot, 305mm length, and 6-pin + 8-pin power connector requirement would be impossible. Data indicates the Pro Vega 64 is 2.2% faster than the AMD Radeon RX 6600 LE, showing it remains competitive against much newer hardware in its class. The verdict, therefore, is straightforward: choose the Pro VII for maximum performance in a standard desktop workstation, and choose the Pro Vega 64 only if the physical form factor of an integrated mobile solution is a hard requirement, accepting a 25-50% performance deficit.

The Pro VII’s memory clock is 1000 MHz (2 Gbps effective), compared to the Pro Vega 64’s 786 MHz (1572 Mbps effective). Both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, indicating parity in API support. The Pro VII is part of the "Radeon Pro Vega (Vega II Series)" generation, while the Pro Vega 64 belongs to the "Radeon Pro Mac (Vega Series)" generation, reflecting their different target platforms. The Pro VII also uses PCIe 4.0 x16, while the Pro Vega 64 is limited to PCIe 3.0 x16.

Specification Differences

The specification sheets reveal several key differences beyond architecture. The Pro VII has 3,840 shading units, 240 TMUs, and 64 ROPs, while the Pro Vega 64 has 4,096 shading units, 256 TMUs, and 64 ROPs. This means the Pro Vega 64 has more compute cores, yet the Pro VII achieves higher performance due to its clock speed and architectural efficiency. The Pro VII’s FP32 compute is rated at 13.06 TFLOPS, versus 11.06 TFLOPS for the Pro Vega 64. FP16 performance follows the same pattern: 26.11 TFLOPS for the Pro VII and 22.12 TFLOPS for the Pro Vega 64, both at a 2:1 ratio.

Memory configurations are markedly different. Both have 16 GB of HBM2, but the Pro VII uses a 4096-bit bus width, yielding 1.02 TB/s of bandwidth, while the Pro Vega 64 uses a 2048-bit bus, yielding 402.4 GB/s.

The Pro VII has a launch MSRP of 1,899 USD, while the Pro Vega 64 has no listed launch MSRP.

Head-to-Head Benchmarks

The benchmark data presents a decisive sweep for the AMD Radeon Pro VII. In Geekbench Metal, the Pro VII scores 108,383 against the Pro Vega 64’s 71,868, a delta of 50.8%. This is the largest performance gap between the two cards and suggests that the Pro VII’s memory bandwidth (1.02 TB/s vs 402.4 GB/s) provides a significant advantage in GPU-compute workloads that leverage Metal’s API. The Pro VII’s high boost clock of 1700 MHz likely contributes to this lead.

In Geekbench OpenCL, the Pro VII scores 90,148 versus 71,094 for the Pro Vega 64, a 26.8% advantage. This smaller margin may reflect OpenCL’s ability to better utilize the Pro Vega 64’s additional shading units (4,096 vs 3,840), narrowing the gap but still leaving the Pro VII ahead. The Pro VII’s FP32 throughput of 13.06 TFLOPS versus 11.06 TFLOPS for the Pro Vega 64 aligns with this outcome.

The Geekbench Vulkan test shows the Pro VII at 92,862 and the Pro Vega 64 at 74,174, a 25.2% difference. This is the closest contest, suggesting that Vulkan’s lower-level API can extract more performance from the older GCN 5.0 architecture. However, the Pro VII still maintains a clear lead, consistent with its overall average benchmark score of 97,131 versus 72,379. The Pro VII’s nearest rival, the AMD Radeon RX 7900M, is only 0.4% ahead in average score, while the NVIDIA Quadro RTX 6000 is 4.7% ahead. The Pro Vega 64’s nearest rival, the NVIDIA TITAN X Pascal, is 0.4% ahead, and the AMD Radeon Vega Frontier Edition is 1.4% behind, illustrating that the Pro Vega 64 sits in a competitive but older performance tier.

Where Each One Wins

The AMD Radeon Pro VII wins on every measurable performance benchmark, making it the superior choice for compute-intensive tasks such as 3D rendering, scientific simulation, and video processing where raw TFLOPS and memory bandwidth are critical. Its 13.06 TFLOPS FP32 and 1.02 TB/s bandwidth are significantly higher than the Pro Vega 64’s 11.06 TFLOPS and 402.4 GB/s. The Pro VII’s 93rd percentile ranking among all GPUs, combined with being only 0.4% behind the much newer AMD Radeon RX 7900M, indicates it remains a highly competitive workstation card. Its PCIe 4.0 interface and 6x mini-DisplayPort outputs make it suitable for high-resolution multi-monitor setups in a desktop workstation.

The AMD Radeon Pro Vega 64, despite losing all benchmarks, wins in the domain of form factor and power integration. As an IGP with no power connectors and no independent dimensions, it is the only option between the two for portable or compact workstation implementations where the Pro VII’s 305mm length and dual-slot footprint are prohibitive. Its 91st percentile ranking shows it is still a capable performer, and its 0.4% lead over the NVIDIA TITAN X Pascal suggests it holds its own against rival professional cards from its era. For users who need a 16 GB HBM2 GPU in a mobile form factor, the Pro Vega 64 is the only choice, despite a 25-50% performance deficit in every benchmark. The data implies that the Pro VII is the performance king, while the Pro Vega 64 serves a specialized, space-constrained niche.
