AMD Radeon Pro WX 8200 vs Intel Arc A770 Comparison

The AMD Radeon Pro WX 8200 and Intel Arc A770 are both end-of-life workstation and enthusiast GPUs, but they represent very different design philosophies. The data shows a near-tie on aggregate benchmark scores—the WX 8200 averages 69408 points against the Arc A770’s 68809—yet the two shared compute tests tell a different story, with the Arc A770 winning both by substantial margins. This analysis walks through the architecture, specifications, and benchmark results to clarify which card suits which workload.

The Verdict

From the available benchmark data, the Intel Arc A770 is the stronger performer in the two tests both cards share. In Geekbench OpenCL, the Arc A770 scores 109175 versus the WX 8200’s 69774, a 36.1% advantage. In Geekbench Vulkan, the Arc A770 scores 94284 against 69041, a 26.8% lead. The head-to-head record is 2–0 in favor of Intel. However, the overall average benchmark score—which for the Arc A770 also includes a 3DMark Steel Nomad DX12 result of 2969—places the WX 8200 slightly ahead by 0.9% (69408 vs 68809). This suggests that while the Arc A770 dominates the OpenCL and Vulkan compute workloads tested, the two cards are otherwise closely matched. For users whose primary applications rely on OpenCL or Vulkan, the Arc A770 is the clear choice. For those who need a card with a 2048‑bit HBM2 memory interface, 4x mini‑DisplayPort 1.4a outputs, or a Radeon Pro pedigree, the WX 8200 remains a viable option—but the benchmark data does not show it winning any shared test.

Architecture Differences

The two GPUs are built on fundamentally different process nodes and architectures. The WX 8200 uses AMD’s GCN 5.0 architecture (Vega 10) on a 14 nm GlobalFoundries process, packing 12,500 million transistors into a 495 mm² die (25.3M transistors per mm²). The Arc A770 uses Intel’s Xe‑HPG architecture (DG2‑512) on a 6 nm TSMC process, with 21,700 million transistors in a 406 mm² die—a density of 53.4M per mm². The Arc A770’s smaller, denser die allows for more compute units: 4096 shading units, 256 TMUs, and 128 ROPs, versus the WX 8200’s 3584 shading units, 224 TMUs, and 64 ROPs. The Arc A770 also adds 32 ray tracing cores, which the WX 8200 lacks. Clock speeds differ as well: the Arc A770 runs at 2100 MHz base and 2400 MHz boost, while the WX 8200 is at 1200 MHz base and 1500 MHz boost. Memory architecture is another major divergence—the WX 8200 uses 8 GB of HBM2 on a 2048‑bit bus, while the Arc A770 uses 16 GB of GDDR6 on a 256‑bit bus. Both achieve the same 512.0 GB/s bandwidth. The Arc A770 supports PCIe 4.0 x16, whereas the WX 8200 is limited to PCIe 3.0 x16. Display outputs also differ: the WX 8200 has 4x mini‑DisplayPort 1.4a, the Arc A770 has 1x HDMI 2.1 and 3x DisplayPort 2.0. API support is newer on the Arc A770—DirectX 12 Ultimate (12_2) and Vulkan 1.4—versus DirectX 12 (12_1) and Vulkan 1.3 on the WX 8200. The launch MSRP of the WX 8200 was 999 USD; the Arc A770 launched at 329 USD.

Head-to-Head Benchmarks

The FACT PACK provides two shared benchmark tests: Geekbench OpenCL and Geekbench Vulkan. In both, the Intel Arc A770 wins decisively. In Geekbench OpenCL, the Arc A770 scores 109175 against the WX 8200’s 69774, a 36.1% gap. In Geekbench Vulkan, the Arc A770 scores 94284 versus 69041, a 26.8% margin. These are large, consistent differences, indicating that the Arc A770’s higher shading unit count, faster clocks, and newer architecture translate directly into superior compute performance in these APIs. The WX 8200 does not win any shared test. Additionally, the Arc A770 has a 3DMark Steel Nomad DX12 score of 2969, but the WX 8200 has no corresponding result in the data, so that test cannot be compared directly. The aggregate average benchmark score—which includes all listed tests for each card—favors the WX 8200 by 0.9% (69408 vs 68809), but this narrow margin is driven by the fact that the two cards have different benchmark sets. When only the shared tests are considered, the Arc A770 is the clear winner.

Where Each One Wins

Based on the data, the Intel Arc A770 wins every head-to-head benchmark it shares with the AMD Radeon Pro WX 8200. Its advantages in OpenCL and Vulkan compute are substantial, and its higher FP32 (19.66 vs 10.75 TFLOPS), texture rate (614.4 vs 336.0 GTexel/s), and pixel rate (307.2 vs 96.00 GPixel/s) support these results. The Arc A770 also offers double the memory capacity (16 GB vs 8 GB) and a newer API set, making it the stronger choice for compute-heavy workloads, large datasets, and applications that can leverage DirectX 12 Ultimate or Vulkan 1.4 features. The WX 8200, on the other hand, wins on the aggregate average benchmark score by 0.9%, though this is a composite that includes different tests. Its 2048‑bit HBM2 memory interface, while delivering the same bandwidth as the Arc A770’s GDDR6, may appeal to users with specific HBM‑friendly workloads, and its 4x mini‑DisplayPort 1.4a outputs suit multi‑monitor professional setups. The WX 8200 also has a slightly higher TDP (230 W vs 225 W), but the difference is negligible. In summary, the Arc A770 is the performance winner in every shared test, while the WX 8200’s edge is limited to the overall average score and its unique memory and display features.
