AMD Radeon Pro VII vs AMD Radeon PRO W6800 Comparison

# AMD Radeon PRO W6800 vs AMD Radeon Pro VII

The AMD Radeon PRO W6800 and AMD Radeon Pro VII are both end-of-life professional workstation cards, but they represent two distinct eras of AMD GPU architecture. The data clearly shows that the newer W6800, built on RDNA 2.0, is the dominant performer across all recorded benchmarks, posting an average benchmark score of 135,396 compared to the Pro VII's 97,131. That is a 39.4% advantage in average score, and the W6800 sits in the 96th percentile of all GPUs while the Pro VII sits in the 93rd. However, the Pro VII retains a unique hardware advantage in memory bandwidth that matters for specific workloads, so the choice is not entirely one-sided.

Head-to-Head Benchmarks

The W6800 wins all three head-to-head comparisons, but the margin varies significantly by API. In Geekbench Metal, the W6800 scores 174,420 against the Pro VII's 108,383, a massive 60.9% lead. This is the largest gap between the two cards in any test and highlights the architectural leap RDNA 2.0 brings to Apple's Metal API. The W6800's advantage narrows considerably in OpenCL, where it scores 121,808 versus 90,148, a 35.1% difference. Still a decisive win, but the gap shrinks by nearly half compared to Metal. In Vulkan, the W6800 scores 109,961 versus 92,862, a modest 18.4% lead. This suggests that Vulkan workloads, which tend to stress raw compute and memory subsystems more evenly, benefit less from the W6800's newer architecture.

The Pro VII's closest rival is the AMD Radeon Instinct MI60, which has an average score of 92,466, putting the Pro VII 5% ahead of that card. It also beats the NVIDIA RTX A4500 by 6% (91,671). However, the Pro VII trails the NVIDIA Quadro RTX 6000 by 4.7% (101,872) and the AMD Radeon RX 7900M by 0.4% (97,487). The W6800, by contrast, is nearly tied with the NVIDIA A10M (135,230, only 0.1% behind) and the NVIDIA RTX 4000 Ada Generation (135,218, 0.1% behind). The W6800 also edges out its own sibling, the W6800X Duo, by 0.3% (135,774) and the Radeon PRO V620 by 0.8% (136,472). In direct comparison, the W6800's average score is 39.4% higher than the Pro VII's, which is a generational leap rather than a incremental upgrade.

Architecture Differences

The W6800 uses the Navi 21 chip on the RDNA 2.0 architecture, while the Pro VII uses the Vega 20 chip on GCN 5.1. Both are manufactured on TSMC's 7 nm process, but the W6800 packs 26,800 million transistors onto a 520 mm² die, versus 13,230 million transistors on a 331 mm² die for the Pro VII. That translates to a transistor density of 51.5M per mm² for the W6800 and 40.0M per mm² for the Pro VII. The W6800 has a base clock of 1575 MHz and a boost clock of 2322 MHz, compared to 1400 MHz base and 1700 MHz boost on the Pro VII. The higher clocks alone explain much of the performance delta, but the architectures differ fundamentally in feature support.

The W6800 supports DirectX 12 Ultimate (12_2), while the Pro VII is limited to DirectX 12 (12_1). The W6800 also includes 60 ray tracing cores, which the Pro VII lacks entirely. For Vulkan, the W6800 supports version 1.4 versus 1.3 on the Pro VII, and both support OpenGL 4.6. The shading unit count is identical at 3840, and both have 240 TMUs, but the ROP count differs: 96 on the W6800 versus 64 on the Pro VII. The W6800's pixel rate is 222.9 GPixel/s versus 108.8 GPixel/s on the Pro VII, and its texture rate is 557.3 GTexel/s versus 408.0 GTexel/s. FP32 compute is 17.83 TFLOPS on the W6800 versus 13.06 TFLOPS on the Pro VII, and FP16 is 35.67 TFLOPS versus 26.11 TFLOPS, both at a 2:1 ratio.

Memory is where the Pro VII fights back. The W6800 has 32 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth at 2000 MHz (16 Gbps effective). The Pro VII has 16 GB of HBM2 on a 4096-bit bus, delivering 1.02 TB/s of bandwidth at 1000 MHz (2 Gbps effective). That is exactly double the bandwidth of the W6800, and it is the single most significant hardware advantage the Pro VII holds. The W6800 makes up for it with double the memory capacity, which matters for large datasets that must reside in VRAM.

FAQ

The Verdict

The data is unambiguous: the AMD Radeon PRO W6800 is the superior card in every benchmark recorded. It wins all three head-to-head tests, posts a 39.4% higher average score, and holds a higher percentile ranking. If you are choosing between these two based solely on performance, the W6800 is the clear pick. Its 60.9% lead in Metal and 35.1% lead in OpenCL make it particularly strong for Apple-centric workflows and general compute. The 18.4% lead in Vulkan is narrower but still decisive.

The Pro VII, however, is not without merit. Its 1.02 TB/s memory bandwidth is exactly double the W6800's 512.0 GB/s, which could be critical for memory-bound workloads that stream large datasets. But the benchmark data shows that this bandwidth advantage does not translate into a win in any of the three tested APIs. The Pro VII also has half the VRAM (16 GB versus 32 GB), which limits its ability to hold large models or scenes entirely in memory. The W6800's 32 GB capacity is a more practical advantage for modern professional workloads than the Pro VII's raw bandwidth. For anyone buying today, the W6800 is the rational choice. The Pro VII is only relevant if you specifically require HBM2 memory characteristics or if you have a workload that is proven to scale with bandwidth over compute, but the benchmark evidence does not support that preference.

Specification Differences

The two cards differ in nearly every measured specification. The W6800 uses the Navi 21 chip with RDNA 2.0 architecture, while the Pro VII uses Vega 20 with GCN 5.1. The W6800 has 26,800 million transistors on a 520 mm² die; the Pro VII has 13,230 million on a 331 mm² die. Transistor density is 51.5M per mm² versus 40.0M per mm². Base clocks are 1575 MHz versus 1400 MHz, and boost clocks are 2322 MHz versus 1700 MHz. Memory configuration diverges completely: 32 GB GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth for the W6800, versus 16 GB HBM2 on a 4096-bit bus with 1.02 TB/s bandwidth for the Pro VII.

The W6800 has 96 ROPs versus 64 on the Pro VII, while shading units (3840) and TMUs (240) are identical. The W6800 includes 60 ray tracing cores; the Pro VII has none. Pixel rate is 222.9 GPixel/s versus 108.8 GPixel/s, and texture rate is 557.3 GTexel/s versus 408.0 GTexel/s. FP32 is 17.83 TFLOPS versus 13.06 TFLOPS, and FP16 is 35.67 TFLOPS versus 26.11 TFLOPS. The W6800 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4; the Pro VII supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. Physical dimensions differ slightly: the W6800 is 267 mm long, 120 mm high, and 50 mm wide; the Pro VII is 305 mm long and 111 mm high. Both are dual-slot, use 1x 6-pin + 1x 8-pin power connectors, and have a 250 W TDP with a 600 W suggested PSU. Both use PCIe 4.0 x16 and have 6x mini-DisplayPort 1.4a outputs. The W6800 launched on 2021-06-07 with a launch MSRP of 2,249 USD; the Pro VII launched on 2020-05-12 with a launch MSRP of 1,899 USD.

Where Each One Wins

The W6800 wins in every benchmark category recorded. It is 60.9% faster in Geekbench Metal, 35.1% faster in Geekbench OpenCL, and 18.4% faster in Geekbench Vulkan. It also wins on memory capacity (32 GB versus 16 GB), ray tracing support (60 cores versus none), pixel rate (222.9 GPixel/s versus 108.8 GPixel/s), texture rate (557.3 GTexel/s versus 408.0 GTexel/s), and compute throughput (17.83 TFLOPS versus 13.06 TFLOPS FP32). It is the better card for any workload that benefits from modern features like DirectX 12 Ultimate, higher boost clocks, or larger frame buffers.

The Pro VII wins in exactly one measurable specification: memory bandwidth. Its 1.02 TB/s of HBM2 bandwidth is double the W6800's 512.0 GB/s, and its 4096-bit bus is 16 times wider than the W6800's 256-bit bus. This makes it theoretically superior for memory-saturation workloads, though the benchmark results do not reflect that advantage in any tested API. The Pro VII also has a smaller physical footprint in height (111 mm versus 120 mm) and a lower launch MSRP (1,899 USD versus 2,249 USD), but those are not performance metrics. For any practical use case measured in the data, the W6800 is the winner. The Pro VII is only defensible if you have a specific workload that is proven to be bandwidth-bound and cannot use more than 16 GB of VRAM. Otherwise, the W6800 is the card to pick.
