AMD Radeon Pro 570X vs AMD Radeon PRO W6400 Comparison

The Verdict

The data splits these two cards cleanly by workload and platform. The AMD Radeon PRO W6400 is the modern, efficient choice for current Windows-based professional tasks. Its benchmark results show a decisive advantage in the two shared tests: it scores 26.9% higher in Geekbench OpenCL and 36.1% higher in Geekbench Vulkan. The AMD Radeon Pro 570X, on the other hand, only appears in the database with a Metal benchmark score of 40066, which the W6400 cannot match because it lacks a Metal result. This makes the 570X the only option for macOS environments that rely on Metal, while the W6400 is the superior pick for cross-platform OpenCL and Vulkan workloads.

For a builder assembling a new professional system, the W6400 is the straightforward recommendation. It outperforms the 570X in every head-to-head test, uses far less power, and is built on a much newer architecture. The 570X is a legacy part for older Mac Pro systems. Its IGP slot width and portable-device-dependent outputs indicate it is meant to be soldered or integrated into a specific Apple platform, not dropped into a standard PC. If you are upgrading an aging Mac, the 570X is the only one of these two that fits that role. If you are building or refreshing a Windows or Linux workstation, the W6400 wins outright.

Architecture Differences

The two cards come from different architectural eras. The W6400 uses the Navi 24 chip based on RDNA 2.0, built on a 6 nm process at TSMC. The 570X uses the Ellesmere chip based on GCN 4.0, built on a 14 nm process at GlobalFoundries. These nodes explain a huge part of the performance delta. The W6400 packs 5,400 million transistors into a 107 mm² die, achieving a density of 50.5 million transistors per mm². The 570X contains 5,700 million transistors in a much larger 232 mm² die, for a density of only 24.6 million per mm². The newer process allows the W6400 to run far more efficiently.

The memory systems also differ. The W6400 uses 4 GB of GDDR6 on a 64-bit bus, delivering 128.0 GB/s bandwidth at 16 Gbps effective. The 570X also has 4 GB of memory, but it is GDDR5 on a 256-bit bus, delivering 217.0 GB/s at 6.8 Gbps effective. So the 570X has more raw bandwidth, but the W6400 has faster memory clock speeds. The feature sets diverge sharply. The W6400 includes 12 ray tracing cores and supports DirectX 12 Ultimate (12_2), while the 570X has no ray tracing cores and only supports DirectX 12 (12_0). Both support OpenGL 4.6, but the W6400 runs Vulkan 1.4 compared to the 570X's Vulkan 1.3.

The W6400 uses a PCIe 4.0 x4 interface, while the 570X uses PCIe 3.0 x16. The 570X has a higher interface width, but the older bus generation. The 570X has more shading units (1792 vs 768) and more texture mapping units (112 vs 48), but both have the same number of render output units (32). The W6400 compensates with much higher clocks: 2039 MHz base and 2321 MHz boost versus 1000 MHz base and 1105 MHz boost for the 570X.

Where Each One Wins

The W6400 wins in every shared benchmark. In Geekbench OpenCL, it scores 35027 against 27604, a 26.9% lead. In Geekbench Vulkan, it scores 39286 against 28859, a 36.1% lead. These are substantial margins that point to the W6400 being the better performer for general compute and modern graphics APIs. The W6400's architecture also supports hardware ray tracing, which the 570X lacks entirely. For any workload that touches DirectX 12 Ultimate features or Vulkan 1.4, the W6400 has the clear advantage.

The 570X only wins in one specific area: Metal performance. Its Geekbench Metal score of 40066 is not directly comparable to the W6400's scores, since the W6400 has no Metal benchmark in the database. This makes the 570X the only choice for applications that require Metal, which is Apple's graphics API. The 570X is also the only one with a 256-bit memory bus, which gives it higher peak bandwidth (217.0 GB/s) than the W6400's 128.0 GB/s. This could matter for bandwidth-bound tasks, but the recorded benchmark results show the W6400 outperforming the 570X in the tests where both were measured.

The 570X has a higher theoretical texture rate (123.8 GTexel/s versus 111.4 GTexel/s) and a higher FP32 throughput (3.960 TFLOPS versus 3.565 TFLOPS). However, those numbers do not translate into actual benchmark wins in the recorded data. The W6400 has a much higher pixel rate, 74.27 GPixel/s versus 35.36 GPixel/s, which helps explain its win in fill-rate tasks.

Head-to-Head Benchmarks

The head-to-head data is limited to two tests, but the results are emphatic. The W6400 wins both the Geekbench OpenCL and Geekbench Vulkan tests against the 570X. The largest victory is in Vulkan, where the W6400 leads by 36.1%. The W6400 scores 39286, while the 570X manages 28859. This gap is substantial and indicates a major advantage in modern cross-platform graphics workloads. The OpenCL lead is smaller but still significant: 35027 versus 27604, a 26.9% difference.

The W6400's OpenCL score also holds up well against its nearest rivals. Its 35027 is only 0.9% behind the AMD Radeon RX Vega 56 (score 37507) and 1.3% behind the NVIDIA Tesla P4 (score 37628). It sits 1.7% ahead of the NVIDIA GeForce GTX TITAN X (score 36530). The 570X's average score of 32176 is 0.7% behind the AMD FirePro S10000 (score 32388) and 0.9% behind the AMD Radeon RX 7900 GRE (score 32456), while it sits 0.9% ahead of the Intel Arc Pro A30M (score 31894). The W6400 is a mid-pack performer among its nearest rivals, while the 570X is also mid-pack, but both cards are close enough that their exact rankings are within a couple of percentage points.

The W6400 also has a higher average benchmark score across all tests in the database, 37157 versus 32176 for the 570X. That's a roughly 15% overall advantage. The 570X's only bright spot is its Metal score of 40066, which is higher than its own OpenCL and Vulkan scores. This suggests the 570X is optimized for Apple's ecosystem, while the W6400 is the more consistent performer in general compute.

Specification Differences

The two cards differ in almost every spec category. The process node is 6 nm for the W6400 versus 14 nm for the 570X. Transistor count is similar (5,400 million for the W6400, 5,700 million for the 570X), but the die size is dramatically different: 107 mm² for the W6400, 232 mm² for the 570X. The clock speeds are also far apart. The W6400 runs at 2039 MHz base and 2321 MHz boost, while the 570X runs at 1000 MHz base and 1105 MHz boost.

Memory type is a major differentiator: GDDR6 for the W6400, GDDR5 for the 570X. The bus width is 64-bit versus 256-bit, and the bandwidth is 128.0 GB/s versus 217.0 GB/s. Effective memory speed is 16 Gbps versus 6.8 Gbps. The W6400 has 12 ray tracing cores, the 570X has none. The W6400 has 768 shading units, 48 TMUs, and 32 ROPs; the 570X has 1792 shading units, 112 TMUs, and 32 ROPs. The W6400's pixel rate is 74.27 GPixel/s versus 35.36 GPixel/s for the 570X. The texture rates are 111.4 GTexel/s versus 123.8 GTexel/s.

Power is a major split. The W6400 has a TDP of 50 W and a suggested PSU of 250 W, while the 570X has a TDP of 150 W and no suggested PSU in the database. The W6400 is a single-slot card with no power connector; the 570X is an IGP. The W6400 uses PCIe 4.0 x4, the 570X uses PCIe 3.0 x16.
