AMD Radeon PRO W7900 vs NVIDIA A10G Comparison

The data is unambiguous: the NVIDIA A10G is the higher-scoring GPU in this comparison, winning both recorded benchmarks, though the margin tells two very different stories depending on the workload. In OpenCL compute, the A10G delivers a decisive 87.3% advantage over the AMD Radeon PRO W7900, while in Vulkan the gap narrows to a modest 6.4%. These results position the two cards for entirely different roles, despite the W7900’s newer architecture and larger memory pool.

Head-to-Head Benchmarks

The Geekbench OpenCL result is a landslide. The NVIDIA A10G scores 158,063 points against the AMD Radeon PRO W7900’s 84,379 points, a delta of 87.3%. This is not a marginal victory; it is a near-doubling of raw compute output. The A10G’s average benchmark score of 151,963 further confirms its consistency, placing it in the 97th percentile of all GPUs. The W7900, by contrast, averages 110,725 points across its benchmarks, sitting in the 94th percentile. The OpenCL gap suggests the A10G’s architecture is far better optimized for this type of general-purpose compute, which is a critical consideration for any database or scientific workload.

The Vulkan test tells a closer story. The A10G scores 145,863, while the W7900 posts 137,070, a 6.4% difference. While the A10G still wins, this margin is within a range where driver optimization or specific workload characteristics could shift the balance. The W7900’s Vulkan score is notably closer to its OpenCL score than the A10G’s, hinting that the AMD card handles graphics-adjacent APIs more consistently, even if it loses the absolute race.

Looking at the rival landscape reinforces the A10G’s standing. Its average score of 151,963 sits 1.1% above the NVIDIA Tesla V100 PCIe 32 GB (150,305) and 9.3% above the AMD Instinct MI100 (139,035). It trails the AMD Radeon Pro W6800X (160,671) by 5.4% and the NVIDIA A100 PCIe 40 GB (162,504) by 6.5%. The W7900’s 110,725 average places it just 1% above the AMD Radeon Pro Vega II (109,617) and 3.2% above the AMD Radeon Pro W6600X (107,342), while falling 2.8% short of the NVIDIA RTX A5500 Mobile (113,944) and 3.2% short of the NVIDIA Tesla V100 SXM2 16 GB (114,395). These deltas show the A10G competing in a higher performance tier, while the W7900 sits in a mid-range bracket.

Architecture Differences

The two GPUs are built on fundamentally different design philosophies. The NVIDIA A10G uses the GA102 chip with the Ampere architecture, fabricated on an 8 nm Samsung process. It packs 28,300 million transistors onto a 628 mm² die, yielding a transistor density of 45.1M per mm². The AMD Radeon PRO W7900 counters with the Navi 31 chip and RDNA 3.0 architecture, built on a 5 nm TSMC process. It contains 57,700 million transistors on a 529 mm² die, achieving a much higher density of 109.1M per mm². The W7900’s smaller, denser die is a direct result of the more advanced manufacturing node, though the A10G’s larger die with fewer transistors suggests a different design trade-off favoring lower power consumption.

The compute resources differ sharply. The A10G features 9,216 shading units, 288 TMUs, and 96 ROPs, alongside 72 RT cores and 288 tensor cores. The W7900 has fewer shading units at 6,144, but more TMUs at 384 and double the ROPs at 192. It also has more RT cores (96) but lacks tensor cores entirely. These numbers explain the benchmark results: the A10G’s higher shading unit count and tensor core presence give it an edge in compute-heavy OpenCL tasks, while the W7900’s higher ROP count and TMU count suggest stronger rasterization throughput, which the Vulkan results partially reflect.

Memory is another major divergence. The A10G offers 24 GB of GDDR6 on a 384-bit bus, with a bandwidth of 600.2 GB/s. The W7900 doubles the capacity to 48 GB of GDDR6 on the same 384-bit bus, but boosts bandwidth to 864.0 GB/s. The W7900’s higher memory clock (2250 MHz effective 18 Gbps) versus the A10G’s 1563 MHz (12.5 Gbps effective) accounts for the bandwidth advantage. For workloads that exceed 24 GB of VRAM, the W7900 is the only option here.

Clock speeds also favor the W7900. Its base clock is 1760 MHz with a boost of 2495 MHz, compared to the A10G’s 1320 MHz base and 1710 MHz boost. This higher clock rate contributes to the W7900’s raw pixel rate of 479.0 GPixel/s and texture rate of 958.1 GTexel/s, both far exceeding the A10G’s 164.2 GPixel/s and 492.5 GTexel/s. However, the A10G achieves a higher FP32 throughput of 31.52 TFLOPS compared to the W7900’s 61.32 TFLOPS? No, that is incorrect per the data: the A10G’s FP32 is 31.52 TFLOPS, and the W7900’s is 61.32 TFLOPS. The W7900 is the clear winner in raw floating-point performance, yet it loses the OpenCL benchmark, indicating that theoretical TFLOPS do not translate directly to real-world scores in this test.

The Verdict

From the data, the NVIDIA A10G is the superior choice for compute-oriented tasks that rely on OpenCL or Vulkan workloads. It wins both head-to-head benchmarks, with a commanding 87.3% lead in OpenCL and a 6.4% lead in Vulkan. Its 97th percentile ranking versus the W7900’s 94th percentile further underscores its higher standing in the overall GPU hierarchy. If the primary use case is general-purpose compute, database processing, or any workload that leverages OpenCL, the A10G is the data-driven pick.

The AMD Radeon PRO W7900, however, is not without merit. It offers 48 GB of memory, double the A10G’s 24 GB, which is a decisive factor for large dataset handling or multi-application virtualization where memory capacity is the bottleneck. Its higher bandwidth (864.0 GB/s vs 600.2 GB/s) and superior pixel/texture rates make it a stronger candidate for graphics rendering tasks that do not rely on the A10G’s winning benchmarks. The W7900 also has display outputs (3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1), whereas the A10G has no outputs, making the W7900 the only viable option for direct display connection.

The verdict hinges on workload priority. For pure compute performance as measured by Geekbench, the A10G wins outright. For memory capacity and graphics output, the W7900 is the only choice. The 87.3% OpenCL delta is too large to ignore for any compute-heavy user, but the 48 GB VRAM advantage is equally non-negotiable for memory-bound tasks.

Where Each One Wins

The NVIDIA A10G wins in both recorded benchmarks and in overall percentile ranking. Its 87.3% OpenCL advantage and 6.4% Vulkan advantage make it the default choice for software that utilizes these APIs. The A10G’s 288 tensor cores also provide a hardware feature the W7900 lacks, which is relevant for any machine learning or AI inference tasks, though no direct benchmark data covers this. Its lower TDP of 150 W, compared to the W7900’s 295 W, and single-slot design versus the W7900’s triple-slot form factor, make it far easier to integrate into dense server environments. The A10G’s end-of-life status is a caveat, but its performance data is current.

The AMD Radeon PRO W7900 wins in memory capacity (48 GB vs 24 GB) and memory bandwidth (864.0 GB/s vs 600.2 GB/s). It also has a significantly higher FP32 throughput of 61.32 TFLOPS versus the A10G’s 31.52 TFLOPS, even though this does not translate to a benchmark win. The W7900’s higher pixel rate (479.0 GPixel/s) and texture rate (958.1 GTexel/s) suggest it would excel in rasterization-heavy rendering tasks, and its display outputs make it suitable for workstation use with direct monitor connectivity. The W7900 is also an active product with a launch MSRP of 3,999 USD, while the A10G is end-of-life.
