GPU Comparison

The NVIDIA A10M and AMD Radeon PRO W7700 are both professional workstation GPUs, but they target different performance profiles. The data shows a clear split: the A10M leads in raw compute workloads, while the W7700 counters with newer architecture and memory technology. The only direct benchmark comparison available is Geekbench OpenCL, where the NVIDIA A10M scores 135,230 against the W7700’s 108,245, a 24.9% advantage. However, the W7700 posts an additional Geekbench Vulkan score of 129,706, which is actually higher than its OpenCL result and within 4% of the A10M’s OpenCL figure. This suggests the two cards have different API strengths, with the A10M dominating in OpenCL but the W7700 showing competitive Vulkan performance. The W7700 also sits in the 95th percentile of all GPUs, just one point below the A10M’s 96th percentile, indicating both are high-end parts despite their different benchmark outcomes.

Head-to-Head Benchmarks

In the single available head-to-head test, the NVIDIA A10M decisively outperforms the AMD Radeon PRO W7700. The A10M scores 135,230 in Geekbench OpenCL, while the W7700 manages only 108,245, giving the NVIDIA card a 24.9% victory. This is a substantial margin, placing the A10M well ahead of the W7700 in this particular workload. The A10M’s average benchmark score is 135,230, while the W7700’s average is 118,976, reflecting the same dominance. When looking at the rival landscape, the A10M sits within 0.9% of the AMD Radeon PRO V620 (136,472) and is essentially tied with the NVIDIA RTX 4000 Ada Generation (135,218) and AMD Radeon PRO W6800 (135,396). This places the A10M in a performance tier where it is trading blows with top-tier professional cards, not just the W7700.

The W7700, on the other hand, shows a different story in its own rival set. Its average score of 118,976 puts it 1.3% ahead of the NVIDIA GB10 (117,393) and 1.6% ahead of the NVIDIA RTX 4000 SFF Ada Generation (117,088). It also leads the NVIDIA Tesla V100 SXM2 16 GB (114,395) by 4% and the NVIDIA RTX A5500 Mobile (113,944) by 4.4%. These deltas are smaller than the A10M’s lead over the W7700, suggesting the W7700 is competitive within its immediate peer group but not a class leader. The W7700’s Vulkan score of 129,706, however, is worth noting, it is 19.8% higher than its own OpenCL score and only 4.1% lower than the A10M’s OpenCL result. This implies that in Vulkan-based applications, the W7700 could close the gap significantly, even if the OpenCL comparison shows a clear A10M win.

Architecture Differences

The architectural divide between these two GPUs is stark. The NVIDIA A10M uses the GA102 chip built on Ampere architecture, manufactured on Samsung’s 8 nm process. The die is massive at 628 mm², housing 28,300 million transistors, which yields a transistor density of 45.1M per mm². In contrast, the AMD Radeon PRO W7700 uses the Navi 32 chip based on RDNA 3.0, with the codename "Wheat Nas," fabricated on TSMC’s 5 nm process. The W7700’s die is significantly smaller at 346 mm², yet it packs nearly the same transistor count at 28,100 million, resulting in a much higher density of 81.2M per mm². The 5 nm node gives AMD a clear manufacturing advantage, allowing for more transistors per area and potentially better power efficiency.

The compute resources differ dramatically. The A10M has 7,168 shading units, 224 texture mapping units (TMUs), and 80 raster output units (ROPs). It also features 56 ray tracing cores and 224 tensor cores, making it a full-featured Ampere implementation. The W7700 has only 3,072 shading units, 192 TMUs, and 96 ROPs, with 48 ray tracing cores but no tensor cores at all. Despite having fewer shading units, the W7700 achieves higher raw throughput: its FP32 performance is 31.95 TFLOPS versus the A10M’s 23.44 TFLOPS. The W7700 also excels in FP16, delivering 63.90 TFLOPS (2:1 ratio), while the A10M only manages 23.44 TFLOPS (1:1 ratio). The A10M’s tensor cores are absent on the W7700, which could be a deciding factor for AI workloads, but the W7700’s raw shader throughput is superior.

Memory architecture also diverges. The A10M comes with 20 GB of GDDR6 on a 320-bit bus, delivering 500.2 GB/s bandwidth. The W7700 has 16 GB of GDDR6 on a 256-bit bus, yet achieves higher bandwidth at 576.0 GB/s thanks to faster memory clocks (18 Gbps effective versus 12.5 Gbps effective). The base and boost clocks also favor AMD: the W7700 runs at 1900 MHz base and 2600 MHz boost, while the A10M is at 975 MHz base and 1635 MHz boost. The W7700’s pixel rate of 249.6 GPixel/s and texture rate of 499.2 GTexel/s both exceed the A10M’s 130.8 GPixel/s and 366.2 GTexel/s, indicating the AMD card is better optimized for fill-rate-bound tasks.

Where Each One Wins

The NVIDIA A10M wins decisively in OpenCL compute based on the head-to-head benchmark. Its 24.9% lead over the W7700 in Geekbench OpenCL suggests it is the stronger choice for applications that rely heavily on this API, such as certain scientific simulations or machine learning frameworks. The A10M’s 20 GB memory capacity is also a practical advantage for workloads that need to hold large datasets on the GPU without spilling to system memory. Its tensor cores, while not benchmarked here, provide hardware acceleration for AI inference that the W7700 lacks entirely. The A10M also holds a higher percentile ranking (96th versus 95th), reinforcing its position as a top-tier performer in the database’s metrics.

The AMD Radeon PRO W7700 wins on architectural modernity and raw throughput. Its 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 are 36% and 173% higher than the A10M’s respective figures, making it the better option for compute tasks that can leverage these rates, such as rendering or video processing. The W7700’s higher memory bandwidth (576.0 GB/s) and faster clocks also benefit memory-intensive workloads. The Vulkan score of 129,706 suggests the W7700 is particularly strong in Vulkan-based applications, where it comes within 4.1% of the A10M’s OpenCL score despite being 24.9% behind in OpenCL. The W7700 also has display outputs (4x DisplayPort 2.1), while the A10M has none, making the AMD card suitable for workstation setups requiring direct monitor connection. The W7700’s dual-slot design and 1x 8-pin power connector are more conventional than the A10M’s single-slot 8-pin EPS, potentially easing installation in standard systems.

Specification Differences

The two cards differ across nearly every core specification. The A10M uses an 8 nm process from Samsung, while the W7700 uses a 5 nm process from TSMC. The A10M has a die size of 628 mm² versus 346 mm² for the W7700, with transistor counts nearly identical (28,300 million vs 28,100 million) but densities of 45.1M/mm² vs 81.2M/mm². The A10M’s base clock is 975 MHz and boost is 1635 MHz, while the W7700 runs at 1900 MHz base and 2600 MHz boost. Memory speed differs: the A10M operates at 1563 MHz (12.5 Gbps effective), the W7700 at 2250 MHz (18 Gbps effective). The A10M has 20 GB memory on a 320-bit bus with 500.2 GB/s bandwidth; the W7700 has 16 GB on a 256-bit bus with 576.0 GB/s bandwidth.

Compute units also differ: the A10M has 7,168 shading units, 224 TMUs, 80 ROPs, 56 RT cores, and 224 tensor cores. The W7700 has 3,072 shading units, 192 TMUs, 96 ROPs, 48 RT cores, and no tensor cores. The A10M’s FP32 is 23.44 TFLOPS and FP16 is 23.44 TFLOPS (1:1), while the W7700 achieves 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 (2:1). Pixel and texture rates are 130.8 GPixel/s and 366.2 GTexel/s for the A10M versus 249.6 GPixel/s and 499.2 GTexel/s for the W7700. The A10M is a single-slot card with an 8-pin EPS power connector, while the W7700 is dual-slot with a 1x 8-pin connector; both suggest a 450 W PSU. The A10M has no display outputs, while the W7700 has 4x DisplayPort 2.1. The A10M is end-of-life, whereas the W7700 launched on 2023-11-12 with a launch MSRP of 999 USD.
