AMD Radeon Pro Vega 64 vs NVIDIA P102-100 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall advantage for the AMD Radeon Pro Vega 64 across the two shared benchmark tests. In the Geekbench OpenCL test, the AMD part scores 71,094 against the NVIDIA P102-100’s 49,602, a 43.3% delta in favor of AMD. This is the largest single performance gap in the comparison. The NVIDIA card trails by a substantial margin in this compute-oriented test, which reflects its more specialized design profile rather than raw capability in general-purpose workloads.

In the Geekbench Vulkan test, the AMD Radeon Pro Vega 64 again takes the win, scoring 74,174 versus 67,454 for the NVIDIA P102-100, a 10% delta. While the margin narrows compared to OpenCL, it remains a consistent victory for AMD. The Vulkan result is notable because it shows that the NVIDIA card is competitive in a lower-level graphics API, but still not enough to overtake AMD’s architecture in this specific benchmark.

The average benchmark score across all recorded tests reinforces the head-to-head picture. The AMD Radeon Pro Vega 64 averages 72,379, while the NVIDIA P102-100 averages 58,528. That is a 23.6% difference in average score, which aligns with the individual test results. The AMD part sits at the 91st percentile among all GPUs in the database, while the NVIDIA part sits at the 88th percentile. Both are high-performing parts, but the AMD card is positioned slightly higher in the overall distribution.

Looking at nearest rivals provides context. The AMD Radeon Pro Vega 64’s closest competitor is the NVIDIA TITAN X Pascal, with an average score of 72,098 and a delta of just 0.4% in favor of AMD. That means the AMD card is effectively neck-and-neck with a flagship Pascal part. The AMD Radeon RX 6650M trails by 0.9%, while the AMD Radeon Vega Frontier Edition is 1.4% ahead. The AMD Radeon RX 6600 LE is 2.2% behind. These tight margins indicate that the Radeon Pro Vega 64 sits within a very competitive cluster of high-end GPUs.

The NVIDIA P102-100’s nearest rivals show a different pattern. The AMD Radeon PRO V710 is 0.2% ahead, the AMD Radeon RX 6950 XT is 0.2% behind, the Intel Arc A570M is 0.5% behind, and the AMD Radeon RX 5600 OEM is 0.8% behind. This cluster is much tighter around the NVIDIA card’s average, suggesting that the P102-100 performs in line with a mid-range to upper-mid-range group, despite its mining-focused design.

Architecture Differences

The architectural divide between these two GPUs is substantial. The AMD Radeon Pro Vega 64 uses the Vega 10 chip built on GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 12,500 million transistors into a 495 mm² die, yielding a transistor density of 25.3 million per square millimeter. The NVIDIA P102-100 uses the GP102 chip based on Pascal architecture, fabricated on a 16 nm process at TSMC. It contains 11,800 million transistors on a 471 mm² die, with a density of 25.1 million per square millimeter. The transistor densities are nearly identical, but AMD achieves it on a larger die with more transistors.

Clock behavior differs significantly. The AMD card runs a base clock of 1250 MHz and a boost clock of 1350 MHz. The NVIDIA card runs substantially higher clocks, with a base of 1582 MHz and a boost of 1683 MHz. Despite this clock advantage, the AMD card still wins on compute throughput in the recorded benchmarks, which points to architectural efficiency differences rather than raw clock speed. The NVIDIA card’s higher clocks do not translate into higher benchmark scores.

Memory configurations are fundamentally different. The AMD Radeon Pro Vega 64 uses 16 GB of HBM2 on a 2048-bit bus, delivering 402.4 GB/s of bandwidth. Memory clock is 786 MHz, which translates to 1572 Mbps effective. The NVIDIA P102-100 uses 5 GB of GDDR5X on a 320-bit bus, delivering 440.3 GB/s of bandwidth. Its memory clock is 1376 MHz, or 11 Gbps effective. The NVIDIA card has a slightly higher bandwidth figure, but the AMD card has over three times the memory capacity. For workloads that need large working sets, that capacity difference is decisive.

Compute unit configurations also diverge. The AMD card has 4096 shading units, 256 texture mapping units, and 64 render output units. The NVIDIA card has 3200 shading units, 200 TMUs, and 80 ROPs. The AMD card leads in shading units and TMUs, while the NVIDIA card has more ROPs. Pixel rate favors NVIDIA at 134.6 GPixel/s versus 86.40 GPixel/s, a 55.8% advantage. Texture rate favors AMD slightly at 345.6 GTexel/s versus 336.6 GTexel/s, a 2.7% margin. FP32 throughput favors AMD at 11.06 TFLOPS versus 10.77 TFLOPS, a 2.7% edge. FP16 throughput is drastically different: AMD delivers 22.12 TFLOPS with a 2:1 ratio, while NVIDIA delivers only 168.3 GFLOPS with a 1:64 ratio. This makes the AMD card vastly more capable in half-precision compute.

Power and physical design differ as well. Both cards are rated at 250 W TDP. The AMD card is an integrated graphics processor with no power connectors and a slot width of IGP, meaning it is designed for portable, Mac-specific integration. The NVIDIA card is a dual-slot card requiring 2x 8-pin power connectors and a 600 W suggested power supply. It has no display outputs, while the AMD card’s display outputs are listed as portable device dependent. The NVIDIA card uses a PCIe 1.0 x4 interface, while the AMD card uses PCIe 3.0 x16. This is a major interface difference that can limit the NVIDIA card’s effective bandwidth to the host system.

API support is similar but not identical. Both support DirectX 12 (12_1) and OpenGL 4.6. The AMD card supports Vulkan 1.3, while the NVIDIA card supports Vulkan 1.4. Neither card has ray tracing cores or tensor cores, so both rely on traditional shader-based rendering.

Where Each One Wins

The AMD Radeon Pro Vega 64 wins in compute-heavy workloads, particularly those that exercise OpenCL and Vulkan. Its 43.3% OpenCL advantage over the NVIDIA P102-100 indicates that general-purpose GPU compute tasks, such as rendering, simulation, or data processing, will see a strong benefit from the AMD card. The 10% Vulkan advantage adds to this picture, suggesting that modern graphics APIs also favor AMD in this comparison.

The AMD card’s 16 GB of HBM2 memory is a clear win for large datasets. Machine learning inference, scientific visualization, or any workload that needs more than 5 GB of working memory will hit a wall on the NVIDIA card. The AMD card has triple the capacity, which is critical for modern workloads that exceed 4-8 GB. The FP16 capability is another differentiator: 22.12 TFLOPS versus 168.3 GFLOPS is a massive gap, making the AMD card suitable for half-precision compute tasks that the NVIDIA card effectively cannot handle at scale.

The NVIDIA P102-100 does have wins in specific areas. Its pixel rate of 134.6 GPixel/s is 55.8% higher than the AMD card’s 86.40 GPixel/s. This suggests that fill-rate-bound workloads, such as certain post-processing effects or traditional rasterization at high resolutions, could favor the NVIDIA card. Its memory bandwidth of 440.3 GB/s is 9.4% higher than the AMD card’s 402.4 GB/s, which can help in bandwidth-bound scenarios that fit within its 5 GB capacity.

The NVIDIA card also has higher clock speeds, which may benefit latency-sensitive workloads that do not scale with parallel throughput. Its 80 ROPs versus 64 on the AMD card reinforce the fill-rate advantage. The PCIe 1.0 x4 interface, however, is a severe bottleneck for any workload that requires frequent host-device data transfers, which limits the practical benefit of its bandwidth advantage in many real-world scenarios.

The Verdict

The benchmark data points to a clear winner for general-purpose compute and modern API workloads: the AMD Radeon Pro Vega 64. Its 43.3% OpenCL lead and 10% Vulkan lead over the NVIDIA P102-100 are decisive. The average benchmark score of 72,379 versus 58,528 places the AMD card in a higher performance tier, at the 91st percentile versus the 88th percentile. For any use case that relies on OpenCL, Vulkan, large memory footprints, or half-precision compute, the AMD card is the better choice.

The NVIDIA P102-100 is a specialized mining GPU with no display outputs and a PCIe 1.0 x4 interface. Its higher pixel rate and memory bandwidth are real advantages, but they are narrow. The fill-rate advantage could matter for specific rasterization tasks, and the bandwidth figure is slightly higher. However, the 5 GB memory capacity and lack of display outputs make it unsuitable for many general-purpose roles. Its 250 W TDP with a 600 W suggested power supply and dual-slot design with 2x 8-pin connectors also make it a less flexible card.

For users who need a portable, integrated GPU with a broad feature set, the AMD Radeon Pro Vega 64 is the clear pick. For users who have a specific workload that is fill-rate bound and fits within 5 GB of memory, the NVIDIA P102-100 might hold a niche advantage, but the data does not show it winning any of the recorded benchmarks. The verdict from the database is unambiguous: the AMD Radeon Pro Vega 64 outperforms the NVIDIA P102-100 in every measured test.
