AMD Radeon Pro Vega 64X vs NVIDIA A10G Comparison

Where Each One Wins

The recorded benchmark data contains only one directly comparable workload between these two accelerators: Geekbench OpenCL. In that test, the NVIDIA A10G is the clear winner, posting a score of 158063 against the AMD Radeon Pro Vega 64X's 78467, a delta of 101.4%. That means the A10G delivers roughly double the OpenCL compute performance of the older AMD part.

However, the two cards do not share a full benchmark suite. The NVIDIA A10G also has a Geekbench Vulkan result of 145863, while the AMD Radeon Pro Vega 64X has a Geekbench Metal result of 83450. These are different API workloads, so they cannot be compared directly, but they do indicate that each card has strengths in its respective ecosystem. The A10G's Vulkan score is close to its OpenCL score, suggesting consistent performance across compute APIs. The Vega 64X's Metal result is slightly above its OpenCL result, indicating a modest advantage in Apple's graphics API environment.

The overall average benchmark scores tell a similar story. The A10G averages 151963 across its recorded tests, placing it in the 97th percentile of all GPUs in the database. The Vega 64X averages 80959, sitting in the 92nd percentile. The gap in average score is 71004 points, or roughly 87.7% higher for the A10G. On a percentile basis, both cards are above the median, but the A10G sits firmly in the top tier while the Vega 64X is closer to the upper-middle range.

Architecture Differences

The architectural divide here is substantial. The NVIDIA A10G uses the GA102 chip built on the Ampere architecture, fabricated on an 8 nm process at Samsung. It packs 28,300 million transistors into a 628 mm² die, yielding a transistor density of 45.1 million per mm². The AMD Radeon Pro Vega 64X, by contrast, uses the Vega 10 chip based on the older GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries. It contains 12,500 million transistors on a 495 mm² die, for a density of 25.3 million per mm². The A10G has more than twice the transistor count on a larger but denser die.

Compute resources diverge sharply. The A10G has 9216 shading units, 288 texture mapping units, and 96 ROPs. It also includes 72 RT cores and 288 tensor cores, hardware that the Vega 64X lacks entirely. The Vega 64X has 4096 shading units, 256 TMUs, and 64 ROPs, with no RT or tensor core equivalents. This means the A10G supports hardware-accelerated ray tracing and tensor operations, while the Vega 64X relies purely on traditional shader compute.

Memory architecture is also fundamentally different. The A10G uses 24 GB of GDDR6 on a 384-bit bus, delivering 600.2 GB/s of bandwidth. The Vega 64X uses 16 GB of HBM2 on a 2048-bit bus, providing 512.0 GB/s. Despite the much wider bus on the AMD part, the A10G still achieves higher total bandwidth due to its faster memory clock. The A10G's memory runs at 1563 MHz (12.5 Gbps effective), while the Vega 64X's HBM2 runs at 1000 MHz (2 Gbps effective).

Feature support differs as well. The A10G supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Vega 64X supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The A10G is the newer part with a more advanced feature set in graphics APIs. The A10G also uses a PCIe 4.0 x16 interface, while the Vega 64X uses PCIe 3.0 x16.

Head-to-Head Benchmarks

The only direct head-to-head benchmark in the database is Geekbench OpenCL. The NVIDIA A10G scores 158063, while the AMD Radeon Pro Vega 64X scores 78467. The delta is 101.4%, meaning the A10G is more than twice as fast in this workload. This is a massive margin, consistent with the architectural gap between an 8 nm Ampere part with 9216 shaders and a 14 nm GCN part with 4096 shaders.

For context, the A10G's nearest rivals in the database include the AMD Radeon Pro W6800X (average score 160671, delta -5.4%), the NVIDIA A100 PCIe 40 GB (162504, delta -6.5%), and the NVIDIA Tesla V100 PCIe 32 GB (150305, delta 1.1%). The A10G sits between the V100 and the W6800X, slightly behind the top-tier compute accelerators but ahead of the previous-generation flagship. Against the AMD Instinct MI100, the A10G leads by 9.3%.

The Vega 64X's nearest rivals tell a different story. The AMD Radeon PRO W6600 averages 81995 (delta -1.3%), the NVIDIA GeForce RTX 5090 averages 79842 (delta 1.4%), the NVIDIA Tesla P100 PCIe 16 GB averages 79605 (delta 1.7%), and the NVIDIA Tesla P100 PCIe 12 GB averages 79396 (delta 2%). The Vega 64X is essentially in a dead heat with these cards, all within a 2% band. This places it in a much lower performance tier than the A10G.

The Verdict

The data points to a decisive conclusion: the NVIDIA A10G is in a different performance class than the AMD Radeon Pro Vega 64X. The OpenCL head-to-head shows a 101.4% advantage for the A10G, and the average benchmark score is roughly 88% higher. The A10G also has more memory (24 GB vs 16 GB), higher bandwidth (600.2 GB/s vs 512.0 GB/s), more shading units (9216 vs 4096), and dedicated RT and tensor cores that the Vega 64X lacks entirely.

The Vega 64X does have one notable advantage in its memory architecture: a 2048-bit bus width compared to the A10G's 384-bit. However, the A10G's faster GDDR6 memory still delivers more total bandwidth, so this wider bus does not translate into a practical win. The Vega 64X also has a Metal benchmark score of 83450, which is its strongest recorded result, but no direct comparison exists with the A10G on that API.

For buyers choosing between these two, the A10G is clearly the better compute accelerator. It is newer, faster, more efficient, and more feature-rich. The Vega 64X is an older part from 2019, built on a 14 nm process, and its performance sits alongside cards like the NVIDIA Tesla P100 and the Radeon PRO W6600. The A10G belongs with the A100 and W6800X tier. The only scenario where the Vega 64X might be preferable is one requiring an integrated GPU with no external power connectors or one specifically targeting Apple's Metal API on a portable device, but for general compute workloads, the A10G wins every recorded comparison.
