Where Each One Wins

The benchmark data divides these two cards into distinct roles. The AMD Radeon Pro Vega 64X wins the only direct head-to-head benchmark, the Geekbench OpenCL test, by a margin of 39.8%. Its average benchmark score of 80959 is 30.8% higher than the W6600M's 61896. The Vega 64X also holds a higher percentile ranking, placing in the 92nd percentile of all GPUs versus the 89th percentile for the W6600M.

However, the W6600M wins in areas that the Vega 64X cannot match. The W6600M is the only one of the two with ray tracing cores, listing 28 of them, and it supports the newer DirectX 12 Ultimate (12_2) API. The Vega 64X is limited to DirectX 12 (12_1). The W6600M also has a much higher boost clock at 2034 MHz, which contributes to its higher pixel rate of 130.2 GPixel/s compared to 93.95 GPixel/s for the Vega 64X.

The W6600M is a newer design, released on 2021-06-07, while the Vega 64X was released on 2019-03-18. Both are marked as end-of-life in the database. The W6600M also lists a predecessor, FirePro Mobile, while the Vega 64X has no predecessor listed.

Architecture Differences

The two GPUs come from entirely different architectural generations. The AMD Radeon Pro Vega 64X uses the Vega 10 chip based on GCN 5.0 architecture, while the AMD Radeon Pro W6600M uses the Navi 23 chip based on RDNA 2.0 architecture. This architectural split explains most of the behavioral differences in the recorded data.

Manufacturing processes differ substantially. The Vega 64X uses a 14 nm process from GlobalFoundries, with 12,500 million transistors on a 495 mm² die. The W6600M uses a 7 nm process from TSMC, with 11,060 million transistors on a 237 mm² die. The smaller die and newer process give the W6600M a transistor density of 46.7M per mm², nearly double the 25.3M per mm² of the Vega 64X.

The memory architectures are fundamentally different. The Vega 64X uses HBM2 memory with a 2048-bit bus, while the W6600M uses GDDR6 memory with a 128-bit bus. The Vega 64X has 16 GB of memory, twice the 8 GB of the W6600M, and offers 512.0 GB/s of bandwidth versus 224.0 GB/s.

Compute resources also differ sharply. The Vega 64X has 4096 shading units and 256 texture mapping units. The W6600M has 1792 shading units and 112 texture mapping units. Both have 64 ROPs. The W6600M adds 28 ray tracing cores, a feature entirely absent from the Vega 64X.

The Vega 64X has a higher FP32 compute throughput at 12.03 TFLOPS, with FP16 support at 64.05 TFLOPS (2:1). The W6600M has 7.290 TFLOPS FP32 and 14.58 TFLOPS FP16 (2:1). The Vega 64X has a higher texture rate at 375.8 GTexel/s, while the W6600M has a higher pixel rate at 130.2 GPixel/s.

API support differs as well. The W6600M supports Vulkan 1.4 and DirectX 12 Ultimate (12_2), while the Vega 64X supports Vulkan 1.3 and DirectX 12 (12_1). Both support OpenGL 4.6. The W6600M also uses a PCIe 4.0 x16 interface, while the Vega 64X uses PCIe 3.0 x16.

Specification Differences

The two cards differ on nearly every major specification field. The Vega 64X has 4096 shading units, 256 TMUs, and 64 ROPs. The W6600M has 1792 shading units, 112 TMUs, and 64 ROPs. The Vega 64X has no ray tracing cores; the W6600M has 28.

Clock speeds: the Vega 64X runs at a 1250 MHz base and 1468 MHz boost. The W6600M runs at a 1224 MHz base and 2034 MHz boost. The memory clock also differs: the Vega 64X runs at 1000 MHz (2 Gbps effective), while the W6600M runs at 1750 MHz (14 Gbps effective).

Memory capacity and type differ: 16 GB HBM2 for the Vega 64X versus 8 GB GDDR6 for the W6600M. The bus widths are 2048 bit and 128 bit, respectively. Bandwidth is 512.0 GB/s versus 224.0 GB/s.

Power draw is substantially different. The Vega 64X has a TDP of 250 W, while the W6600M has a TDP of 90 W. Both are listed as IGP slot width with no power connectors, and both have display outputs described as portable device dependent.

The process node, foundry, die size, and transistor count all differ, as covered in the architecture section. The bus interface differs: PCIe 3.0 x16 for the Vega 64X, PCIe 4.0 x16 for the W6600M. Release dates differ: 2019-03-18 for the Vega 64X and 2021-06-07 for the W6600M. The Vega 64X has no predecessor listed, while the W6600M lists FirePro Mobile as its predecessor.

Head-to-Head Benchmarks

The database records one shared benchmark between these two cards: Geekbench OpenCL. The AMD Radeon Pro Vega 64X scores 78467, and the AMD Radeon Pro W6600M scores 56140. The delta is 39.8% in favor of the Vega 64X. This is a decisive win for the older card in raw compute throughput.

The Vega 64X also has a Geekbench Metal score of 83450, which is its strongest single result. The W6600M has a Geekbench Vulkan score of 67652, which is its strongest single result. These tests are not shared between the cards, so direct comparison is limited to averages and percentiles.

Average benchmark scores confirm the OpenCL result. The Vega 64X averages 80959 across all recorded tests, beating the W6600M's 61896 by 30.8%. The nearest rivals in the database place these results in context. The Vega 64X sits 1.3% behind the AMD Radeon PRO W6600 (81995) and 1.4% ahead of the NVIDIA GeForce RTX 5090 (79842). The W6600M sits 0.3% behind the AMD Radeon 8050S (62108) and 2.6% ahead of both the NVIDIA GeForce RTX 4090 (60347) and the Intel Arc Pro A60 (60326).

The pixel rate comparison shows the W6600M ahead at 130.2 GPixel/s versus 93.95 GPixel/s for the Vega 64X, a 38.6% advantage driven by its higher boost clock. The texture rate comparison goes the other way, with the Vega 64X at 375.8 GTexel/s versus 227.8 GTexel/s for the W6600M, a 65% advantage driven by its larger TMU count.

FP32 throughput favors the Vega 64X at 12.03 TFLOPS versus 7.290 TFLOPS, a 65% advantage. FP16 throughput also favors the Vega 64X at 24.05 TFLOPS versus 14.58 TFLOPS, a 65% advantage. The W6600M counters with a 2034 MHz boost clock, which is 38.6% higher than the Vega 64X's 1468 MHz boost clock.

The Verdict

The AMD Radeon Pro Vega 64X is the choice for raw compute throughput. It wins the only direct head-to-head benchmark by 39.8%, has a 30.8% higher average benchmark score, and offers more than double the memory bandwidth at 512.0 GB/s versus 224.0 GB/s. Its 16 GB of HBM2 memory and 2048-bit bus make it the stronger candidate for memory-heavy workloads. Its higher FP32 and FP16 throughput, along with its higher texture rate, point to compute-oriented tasks as the primary fit.

The AMD Radeon Pro W6600M is the choice for modern feature support and efficiency. It is the only card with ray tracing cores, supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, and uses a PCIe 4.0 x16 interface. Its TDP of 90 W is far lower than the 250 W of the Vega 64X. Its higher boost clock of 2034 MHz and higher pixel rate of 130.2 GPixel/s suggest it handles pixel-bound work efficiently, even with fewer shading units.

The data shows a trade-off between generations. The Vega 64X belongs to an older architecture with a larger die, more transistors, and more compute units. The W6600M belongs to a newer architecture with a smaller die, higher density, and modern API support. Users who prioritize compute performance and memory capacity should select the Vega 64X. Users who prioritize ray tracing, API compatibility, and lower power draw should select the W6600M.

Both cards are end-of-life, so availability may factor into any decision, though the database does not record pricing for either. The percentile rankings reinforce the distinction: the Vega 64X at the 92nd percentile of all GPUs is a higher-performing part overall, while the W6600M at the 89th percentile still competes well within its class. The nearest rivals for each card show that the Vega 64X trades places with desktop-class GPUs like the RTX 5090 and Tesla P100 variants, while the W6600M trades places with integrated and mobile-class parts like the AMD Radeon 8050S and RTX 4090.
