AMD Radeon Pro W6600M vs AMD Radeon VII Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear picture: the AMD Radeon VII wins both available head-to-head tests, and it wins them by substantial margins. In Geekbench OpenCL, the Radeon VII scores 91,947 against the Radeon Pro W6600M's 56,140, a delta of 63.8%. That is not a narrow lead; it is a dominant one. The Radeon VII is effectively two-thirds faster in this compute-oriented workload. In Geekbench Vulkan, the gap narrows but remains decisive: the Radeon VII posts 91,788 versus 67,652 for the Pro W6600M, a 35.7% advantage. Both scores align with the broader performance positioning, where the Radeon VII's average benchmark score of 66,004 sits nearly 7% above the Pro W6600M's 61,896.

The Radeon VII's wins are consistent with its hardware endowment. It carries 3,840 shading units, 240 texture mapping units, and 64 ROPs. The Pro W6600M counters with 1,792 shading units, 112 TMUs, and the same 64 ROPs. The Radeon VII's FP32 throughput is 13.44 TFLOPS versus 7.29 TFLOPS for the Pro W6600M. That is an 84% raw compute advantage, and the OpenCL result reflects that gap closely. The Vulkan test is less lopsided, which suggests that architectural efficiency or driver optimization partially compensates for the Pro W6600M's smaller compute footprint.

Context from the nearest rivals reinforces the Radeon VII's standing. Its average score of 66,004 places it 1.4% ahead of the NVIDIA Tesla P40 (65,095), 2.8% ahead of the AMD Radeon Pro WX 9100 (64,212), and 3.4% ahead of the NVIDIA CMP 30HX (63,842). Only the NVIDIA Tesla T4 (66,733) edges it out, and by just 1.1%. The Pro W6600M, meanwhile, sits at the 89th percentile of all GPUs, with its nearest rival being the AMD Radeon 8050S at 62,108 — a mere 0.3% gap. Interestingly, the Pro W6600M's rival list includes the NVIDIA GeForce RTX 4090 at 60,347, which it leads by 2.6%, and the Intel Arc Pro A60 at 60,326, also by 2.6%. The Radeon VII, at the 90th percentile, is one percentile point higher.

Q: Do both GPUs support the same DirectX version?

A: No. The Radeon VII supports DirectX 12 (12_1), while the Radeon Pro W6600M supports DirectX 12 Ultimate (12_2). Both support OpenGL 4.6 and Vulkan, but the Pro W6600M lists Vulkan 1.4 versus Vulkan 1.3 for the Radeon VII.

Q: Which GPU has a higher pixel fill rate?

A: The Radeon Pro W6600M. It achieves 130.2 GPixel/s, while the Radeon VII achieves 112.0 GPixel/s, despite the Radeon VII having a much higher texture rate (420.0 GTexel/s versus 227.8 GTexel/s).

Architecture Differences

The two GPUs belong to different architectural generations and design philosophies. The Radeon VII is built on the Vega 20 chip using the GCN 5.1 architecture, part of the Vega II generation. The Radeon Pro W6600M uses the Navi 23 chip with the RDNA 2.0 architecture, part of the Radeon Pro Mobile (W6x00M) generation. Both are fabricated on a 7 nm process at TSMC, but the transistor density differs: the Radeon VII packs 13,230 million transistors into a 331 mm² die, yielding 40.0M transistors per mm². The Pro W6600M fits 11,060 million transistors into a 237 mm² die, achieving a higher density of 46.7M per mm².

Memory architecture is another major divergence. The Radeon VII uses 16 GB of HBM2 on a 4096-bit bus, delivering 1.02 TB/s of bandwidth. The Pro W6600M uses 8 GB of GDDR6 on a 128-bit bus, with 224.0 GB/s of bandwidth. That is a 4.5x difference in raw memory bandwidth. The Radeon VII's memory clock is listed at 1000 MHz with 2 Gbps effective, while the Pro W6600M's memory runs at 1750 MHz with 14 Gbps effective. The Radeon VII's wider bus compensates for the lower per-pin speed.

Compute resources differ sharply. The Radeon VII has 3,840 shading units, 240 TMUs, and 64 ROPs. The Pro W6600M has 1,792 shading units, 112 TMUs, and 64 ROPs. The Radeon VII also leads in FP32 (13.44 TFLOPS versus 7.29 TFLOPS) and FP16 (26.88 TFLOPS versus 14.58 TFLOPS, both at 2:1 ratio). However, the Pro W6600M introduces 28 ray tracing cores, which the Radeon VII lacks entirely. Neither GPU has tensor cores.

The Radeon VII is a desktop card with a dual-slot form factor, 280 mm length, 125 mm height, and 40 mm width. It requires two 8-pin power connectors and a 600 W suggested PSU, with a TDP of 295 W. The Pro W6600M is an integrated GPU (IGP) with no slot width, no power connectors, no listed dimensions, and a TDP of just 90 W. It connects via PCIe 4.0 x16, while the Radeon VII uses PCIe 3.0 x16. Display outputs also differ: the Radeon VII has 1x HDMI 2.0b and 3x DisplayPort 1.4a, while the Pro W6600M's outputs are listed as "Portable Device Dependent."

Where Each One Wins

The Radeon VII wins in raw compute throughput. It dominates the OpenCL and Vulkan benchmarks, with leads of 63.8% and 35.7% respectively. Its memory bandwidth of 1.02 TB/s is unmatched by the Pro W6600M's 224 GB/s, making it the clear choice for workloads that saturate memory — large dataset processing, high-resolution compute tasks, or any application that benefits from a 4096-bit bus. Its 16 GB frame buffer doubles the Pro W6600M's 8 GB, which matters for holding larger working sets in GPU memory. The Radeon VII also has higher FP32 and FP16 throughput, and its texture rate of 420.0 GTexel/s nearly doubles the Pro W6600M's 227.8 GTexel/s.

The Pro W6600M wins in efficiency and modern feature support. Its TDP of 90 W is less than one-third of the Radeon VII's 295 W, and it requires no external power connectors. It has 28 ray tracing cores, enabling hardware-accelerated ray tracing that the Radeon VII cannot perform. It supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, both newer than the Radeon VII's DirectX 12 (12_1) and Vulkan 1.3. It also has a higher pixel rate (130.2 GPixel/s versus 112.0 GPixel/s) despite having fewer shading units, a benefit of its higher boost clock (2034 MHz versus 1750 MHz). Its PCIe 4.0 x16 interface doubles the bandwidth of the Radeon VII's PCIe 3.0 x16. The Pro W6600M is also newer, released in 2021 versus 2019.

The percentile rankings are close — 90th for the Radeon VII, 89th for the Pro W6600M — but the Radeon VII's average score is higher. However, the Pro W6600M's nearest rival list shows it competing well against much newer hardware, including the RTX 4090, which it leads by 2.6%. That suggests the Pro W6600M's architectural efficiency narrows the gap in certain workloads.

The Verdict

The data supports a straightforward split. For users who prioritize raw compute performance in OpenCL and Vulkan workloads, the AMD Radeon VII is the stronger card. It wins both head-to-head benchmarks by margins of 63.8% and 35.7%, and its average benchmark score of 66,004 is 6.6% higher than the Pro W6600M's 61,896. It offers more than double the memory bandwidth, twice the frame buffer, and nearly double the FP32 throughput. Its 90th percentile ranking among all GPUs is one point higher than the Pro W6600M's 89th.

For users who need a mobile, low-power solution with modern ray tracing and the latest API support, the AMD Radeon Pro W6600M is the only viable choice. Its 90 W TDP, IGP form factor, and lack of power connectors make it suitable for portable devices. The 28 ray tracing cores, DirectX 12 Ultimate support, and Vulkan 1.4 compatibility give it features the Radeon VII simply does not have. Its higher pixel rate (130.2 GPixel/s) and boost clock (2034 MHz) also indicate better fill-rate efficiency in certain rendering paths.

The Radeon VII is end-of-life with a successor (Navi) already named; the Pro W6600M is also end-of-life but has no listed successor. The Radeon VII's launch MSRP was 699 USD. Neither card is in current production. The choice ultimately depends on whether the workload demands the Radeon VII's brute compute and memory resources, or the Pro W6600M's efficiency, portability, and modern feature set. The benchmark results favor the Radeon VII on raw performance, but the Pro W6600M's architectural advantages make it the more future-proof option in API support and ray tracing capability. There is no universal winner; the data supports each card for different use cases.
