AMD Radeon Pro Vega II vs AMD Radeon PRO W7700 Comparison

The AMD Radeon PRO W7700 is the clear performance winner over the AMD Radeon Pro Vega II, taking both head-to-head benchmark victories with a decisive 30.2% lead in Vulkan and a solid 9.3% advantage in OpenCL. The W7700 achieves this on a dramatically newer 5 nm process with over double the transistor density, while the Vega II counters with double the memory capacity and significantly higher memory bandwidth. Benchmark results place the W7700 in the 95th percentile of all GPUs and the Vega II in the 94th, but the W7700's average benchmark score of 118,976 versus 109,617 shows a meaningful generational gap that goes well beyond the percentile rankings.

Architecture Differences

The architectural gap between these two GPUs is substantial, reflecting four years of development between their release dates. The W7700 is built on RDNA 3.0 with the Navi 32 chip and the "Wheat Nas" codename, part of the Radeon Pro Navi (Navi III Series) generation. In contrast, the Vega II uses GCN 5.1 with the Vega 20 chip, belonging to the Radeon Pro Mac (Vega Series) generation. This is a fundamental shift from GCN to RDNA, which explains many of the performance differences.

The manufacturing process differs significantly: the W7700 uses a 5 nm TSMC node with 28,100 million transistors on a 346 mm² die, achieving an 81.2M transistors per mm² density. The Vega II uses a 7 nm TSMC node with 13,230 million transistors on a 331 mm² die, for a 40.0M per mm² density. The W7700 packs more than double the transistors into a similar die area, which directly enables its higher compute throughput.

Memory architecture is a major differentiator. The W7700 uses 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth, while the Vega II uses 32 GB of HBM2 on a 4096-bit bus with 825.3 GB/s bandwidth. The Vega II's HBM2 provides superior bandwidth and double the capacity, but the W7700's GDDR6 operates at a much higher effective speed of 18 Gbps versus the Vega II's 1612 Mbps effective.

Compute resources are distributed differently. The W7700 has 3072 shading units, 192 TMUs, 96 ROPs, and 48 ray tracing cores. The Vega II has 4096 shading units, 256 TMUs, and 64 ROPs, but no ray tracing cores. Despite having fewer shading units and TMUs, the W7700 achieves higher pixel and texture rates: 249.6 GPixel/s and 499.2 GTexel/s versus the Vega II's 110.1 GPixel/s and 440.3 GTexel/s.

Feature support also differs. The W7700 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Vega II is limited to DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The W7700 uses PCIe 4.0 x16, while the Vega II uses the Apple MPX bus interface, reflecting its Mac-oriented design. Display outputs are another split: the W7700 offers 4x DisplayPort 2.1, while the Vega II offers 1x HDMI 2.0b and 4x Thunderbolt.

Head-to-Head Benchmarks

The head-to-head data shows a clean sweep for the W7700 in both available tests. In Geekbench OpenCL, the W7700 scores 108,245 against the Vega II's 99,048, a 9.3% advantage. This is a meaningful but not overwhelming margin, indicating that the Vega II's higher bandwidth and memory capacity help it remain competitive in compute-oriented OpenCL workloads despite its older architecture.

The Vulkan results tell a different story. The W7700 scores 129,706 versus the Vega II's 99,621, a 30.2% lead. This is a substantial gap that highlights the W7700's architectural efficiency under modern graphics APIs. The Vega II's lack of ray tracing cores and older GCN design likely contribute to this larger deficit in Vulkan, which tends to benefit from newer hardware features and driver optimizations.

The average benchmark scores reinforce this trend. The W7700 averages 118,976 across its two benchmarks, while the Vega II averages 109,617 across its three benchmarks, which include a Metal score of 130,183 that is not part of the head-to-head comparison. Even with that strong Metal showing, the Vega II's overall average trails the W7700 by 8.5%. The W7700's nearest rivals include the NVIDIA GB10 at 117,393 (1.3% behind) and the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (1.6% behind), while the Vega II's closest competitor is the AMD Radeon PRO W7900 at 110,725, which is 1% behind.

The W7700 wins 2 out of 2 head-to-head tests. The Vega II does not win any. The largest single-test margin is the 30.2% Vulkan gap, while the smallest is the 9.3% OpenCL gap. These results indicate that the W7700 is not just faster on average but also scales better with API-level demands.

The Verdict

The data clearly favors the AMD Radeon PRO W7700 for anyone prioritizing raw performance and modern feature support. It wins both head-to-head benchmarks, delivers double the FP32 compute (31.95 TFLOPS versus 14.09 TFLOPS), and does so with a 190 W TDP versus the Vega II's 475 W TDP. The W7700 also adds ray tracing cores and supports DirectX 12 Ultimate, making it the more future-proof choice for modern workloads.

The AMD Radeon Pro Vega II remains relevant only for specific use cases that demand its unique memory configuration. With 32 GB of HBM2 and 825.3 GB/s bandwidth, it offers double the capacity and 43.2% more bandwidth than the W7700. For workloads that are memory-capacity-bound or bandwidth-bound, the Vega II could still be the better option, especially given its strong Metal score of 130,183, which exceeds any benchmark the W7700 has recorded.

The W7700's 95th percentile ranking versus the Vega II's 94th percentile is a narrow gap, but the average score difference of 9,359 points is more telling. The W7700's nearest rival, the NVIDIA GB10, sits only 1.3% behind, suggesting the W7700 is competitive within its own generation. The Vega II's nearest rival is the AMD Radeon PRO W7900, which sits 1% ahead, placing the Vega II at the lower end of its performance tier.

For most buyers, the W7700 is the obvious choice due to its superior benchmark results, lower power draw, and modern API support. The Vega II is a niche product that only makes sense for those who specifically need its memory capacity or are locked into the Apple MPX ecosystem. The data shows a clear generational win for the W7700.

Where Each One Wins

The AMD Radeon PRO W7700 wins in every head-to-head benchmark category and dominates in raw compute metrics. It is the superior choice for FP32 and FP16 workloads, offering 31.95 TFLOPS and 63.90 TFLOPS respectively, which are more than double the Vega II's figures. The W7700 also wins on pixel rate (249.6 GPixel/s versus 110.1 GPixel/s) and texture rate (499.2 GTexel/s versus 440.3 GTexel/s), making it better suited for graphics rendering and real-time visualization. Its 48 ray tracing cores and DirectX 12 Ultimate support give it a clear edge in ray-traced workloads and modern game development. The W7700's lower TDP of 190 W and dual-slot design make it easier to integrate into standard workstations, and its PCIe 4.0 x16 interface is more universally compatible than the Vega II's Apple MPX bus.

The AMD Radeon Pro Vega II wins on memory capacity and bandwidth. With 32 GB of HBM2 on a 4096-bit bus, it provides 825.3 GB/s of bandwidth, which is 43.2% more than the W7700's 576.0 GB/s. This makes the Vega II the better choice for workloads that are memory-bound, such as large dataset processing or high-resolution texture streaming. The Vega II also has more shading units (4096 versus 3072) and TMUs (256 versus 192), though the W7700's higher clocks and newer architecture overcome this in practice. The Vega II's strong Metal benchmark score of 130,183, which exceeds any score the W7700 has recorded in OpenCL or Vulkan, suggests it may be preferable for macOS environments via its Thunderbolt outputs and Apple MPX interface. Its end-of-life production status, however, means it is no longer being manufactured, while the W7700 remains an active product.
