AMD Radeon PRO W7800 vs NVIDIA A10G Comparison

The NVIDIA A10G and AMD Radeon PRO W7800 are both professional workstation GPUs that land in the 98th percentile of all tested graphics cards, yet they approach performance from opposite directions. The A10G posts an average benchmark score of 151,963, while the W7800 reaches 160,108, a 5.1% advantage for the AMD card according to the nearestRivals delta. Head-to-head results, however, tell a more nuanced story: the A10G wins the OpenCL test by 2.4%, while the W7800 crushes the Vulkan test by 12.1%. These two cards are not interchangeable; they are optimized for different workloads and system constraints.

Head-to-Head Benchmarks

In the Geekbench OpenCL test, the NVIDIA A10G scores 158,063 against the AMD Radeon PRO W7800’s 154,366, giving the A10G a 2.4% victory. This is a narrow but consistent lead, suggesting the A10G’s compute pipeline is slightly better tuned for OpenCL’s general-purpose GPU tasks. The A10G’s 9,216 shading units and 288 tensor cores likely contribute to this edge, though the data does not isolate the cause. Meanwhile, the W7800’s 4,480 shading units are fewer, but its higher clock speeds (1,895 MHz base, 2,525 MHz boost) may offset that deficit in raw compute.

The Vulkan benchmark flips the outcome decisively. The W7800 scores 165,849 versus the A10G’s 145,863, a 12.1% margin. This is a substantial gap, indicating that the RDNA 3.0 architecture handles Vulkan’s low-level API with far greater efficiency. The W7800’s 128 ROPs and 707.0 GTexel/s texture rate outpace the A10G’s 96 ROPs and 492.5 GTexel/s, which likely explains the rendering-heavy advantage. The A10G’s Vulkan score is also its weaker benchmark, while the W7800’s Vulkan result is its stronger one—a clear sign of divergent strengths.

When placed against the broader field, both cards sit in similar territory. The A10G’s average score of 151,963 is 5.1% behind the W7800, but it is 5.7% ahead of the AMD Radeon Pro W6800X Duo (143,766) and roughly 5% behind the Radeon Pro W6900X (160,049) and W6800X (160,309). The W7800’s average of 160,108 is essentially tied with the W6900X (0% delta) and W6800X (-0.1%), slightly behind the RTX A5500 (-0.6%), and 3.6% behind the Radeon PRO W7900 (166,059). Thus, the W7800 is a mid-to-high performer in its class, while the A10G sits just below that tier.

The Verdict

The data points to a clear split: pick the NVIDIA A10G for OpenCL-heavy workloads, for systems with tight power budgets, or when a single-slot form factor is mandatory. Its 150 W TDP and single-slot design make it easier to integrate into dense servers, and its 600.2 GB/s memory bandwidth exceeds the W7800’s 576.0 GB/s despite the smaller 24 GB capacity. The A10G also offers 288 tensor cores, which may benefit AI inference tasks—though no benchmark in this dataset directly measures that.

Choose the AMD Radeon PRO W7800 for Vulkan-based rendering, for tasks that demand more memory (32 GB vs 24 GB), or when display outputs are required. Its 12.1% Vulkan lead is substantial, and its higher pixel rate (323.2 GPixel/s) and texture rate (707.0 GTexel/s) indicate superior rasterization throughput. The W7800 also doubles FP16 performance (90.50 TFLOPS vs 31.52 TFLOPS) and offers higher FP32 compute (45.25 TFLOPS vs 31.52 TFLOPS), making it the stronger raw compute card overall. However, its dual-slot design and 260 W TDP require more physical space and power headroom.

Architecture Differences

The NVIDIA A10G uses the GA102 chip built on Samsung’s 8 nm process, with 28,300 million transistors on a 628 mm² die, yielding a density of 45.1M / mm². The AMD Radeon PRO W7800 uses Navi 31 on TSMC’s 5 nm node, packing 57,700 million transistors into a smaller 529 mm² die, achieving a density of 109.1M / mm²—more than double. This density advantage explains the W7800’s higher clock speeds (2,525 MHz boost vs 1,710 MHz) and its superior FP32 and FP16 throughput.

The A10G is built on the Ampere architecture, which includes 288 tensor cores and 72 RT cores. The W7800, based on RDNA 3.0, has 70 RT cores but no tensor cores. The A10G’s FP16 performance is 1:1 with FP32 (both 31.52 TFLOPS), while the W7800 offers 2:1 FP16 (90.50 TFLOPS) over FP32 (45.25 TFLOPS). This makes the W7800 far more capable in half-precision compute. The A10G’s memory interface is wider (384-bit vs 256-bit) but slower in effective speed, resulting in slightly higher bandwidth (600.2 vs 576.0 GB/s). The W7800’s 32 GB frame buffer is 8 GB larger, which is critical for large datasets or high-resolution textures.

Where Each One Wins

NVIDIA A10G wins in:

• OpenCL performance (2.4% ahead in the head-to-head)
• Memory bandwidth (600.2 GB/s vs 576.0 GB/s)
• Power efficiency (150 W TDP vs 260 W) and single-slot form factor
• Tensor core availability (288 vs none)
• Lower system PSU requirement (450 W vs 600 W)

AMD Radeon PRO W7800 wins in:

• Vulkan performance (12.1% ahead)
• Memory capacity (32 GB vs 24 GB)
• Raw compute throughput (45.25 TFLOPS FP32, 90.50 TFLOPS FP16)
• Pixel rate (323.2 GPixel/s vs 164.2) and texture rate (707.0 GTexel/s vs 492.5)
• Display outputs (3x DP2.1 + 1x mini-DP2.1)
• Higher boost clock (2,525 MHz vs 1,710 MHz)

The A10G is the better choice for OpenCL compute tasks, especially in space-constrained or power-limited environments where its single-slot design and 150 W TDP shine. The W7800 is the clear winner for Vulkan rendering, memory-heavy workloads, and any scenario requiring display connectivity. The data does not indicate a single overall winner—the two cards are specialized tools with complementary strengths.
