AMD Radeon Pro W6600M vs AMD Radeon RX 7700S Comparison

The AMD Radeon Pro W6600M and AMD Radeon RX 7700S are both mobile GPUs from AMD, but they target very different segments. The data shows the RX 7700S holds a decisive performance advantage in the single shared benchmark, while the Pro W6600M counters with a more mature architecture and a longer production history. The Geekbench OpenCL scores reveal a substantial gap, but the story is more nuanced when examining the underlying silicon and feature sets.

Head-to-Head Benchmarks

The only directly comparable benchmark in the data is Geekbench OpenCL, and the results are not close. The AMD Radeon RX 7700S scores 69,728, while the AMD Radeon Pro W6600M trails with 53,414. This represents a delta of -23.4% for the older card, meaning the RX 7700S is roughly 30% faster than the Pro W6600M in this compute-heavy test. This is a significant margin that will translate into real-world differences for any workload leveraging OpenCL.

The Pro W6600M’s average benchmark score of 53,414 places it just 0.1% behind the AMD Radeon RX 6900 XT (53,489) and 0.4% behind the NVIDIA GeForce RTX 4080 SUPER (53,610). It also edges out the NVIDIA GeForce RTX 5070 Ti (52,086) by 2.5%. For a mobile workstation part, this positioning is respectable, but it is clearly outclassed by the newer RX 7700S.

Looking at the RX 7700S from its own perspective, its average score of 52,505 is actually lower than its single Geekbench OpenCL result because it also includes a 3DMark Steel Nomad DX12 score of 2,185 and a Geekbench Vulkan score of 85,603. The 3DMark result, while not directly comparable to the Pro W6600M, indicates strong DirectX 12 gaming performance. The Vulkan score of 85,603 is notably higher than its OpenCL score, suggesting the RDNA 3.0 architecture scales particularly well with Vulkan’s lower-overhead API.

The RX 7700S’s average score puts it 0.8% ahead of both the NVIDIA GeForce RTX 5070 Ti (52,086) and the NVIDIA GeForce RTX 4080 (52,085). It sits 1.8% behind the AMD Radeon RX 6900 XT (53,489). This places the mobile RX 7700S in the same performance tier as desktop flagship cards from previous generations, which is impressive for a 100 W IGP. The Pro W6600M, in contrast, sits firmly in the mid-range desktop class, trading blows with the RTX 4070-class parts from its era.

Architecture Differences

The two GPUs represent two distinct generations of AMD graphics architecture. The Pro W6600M is built on RDNA 2.0, using the Navi 23 chip, while the RX 7700S employs the newer RDNA 3.0 architecture with the Navi 33 chip, codenamed "Hotpink Bonefish." This generational leap is the primary driver of the performance gap.

Manufacturing processes differ significantly. The Pro W6600M uses a 7 nm TSMC process, whereas the RX 7700S is fabricated on a more advanced 6 nm TSMC node. The newer node allows the RX 7700S to pack 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2M per mm². The Pro W6600M, by comparison, contains 11,060 million transistors on a larger 237 mm² die, resulting in a density of just 46.7M per mm². The RX 7700S achieves higher density on a smaller die, which is a clear sign of architectural efficiency improvements.

Compute resources also favor the RX 7700S. It features 2,048 shading units, 128 texture mapping units (TMUs), and 32 ray tracing cores. The Pro W6600M has 1,792 shading units, 112 TMUs, and 28 ray tracing cores. Both GPUs have 64 raster operation units (ROPs), but the RX 7700S’s higher clock speeds amplify its advantage elsewhere. The RX 7700S boosts to 2,500 MHz with a game clock of 2,200 MHz, while the Pro W6600M maxes out at 2,034 MHz.

The memory subsystems are similar in width but differ in speed. Both use 8 GB of GDDR6 on a 128-bit bus, but the RX 7700S runs its memory at 2,250 MHz (18 Gbps effective), delivering 288.0 GB/s of bandwidth. The Pro W6600M’s memory runs at 1,750 MHz (14 Gbps effective), providing 224.0 GB/s. This 28.6% bandwidth advantage for the RX 7700S contributes significantly to its compute lead.

Where Each One Wins

The RX 7700S wins decisively in raw compute performance, as evidenced by its 23.4% lead in Geekbench OpenCL. Its higher FP32 throughput of 20.48 TFLOPS versus the Pro W6600M’s 7.290 TFLOPS makes it the clear choice for any workload that leverages general-purpose compute. The RX 7700S also offers superior pixel fill rate (160.0 GPixel/s vs 130.2 GPixel/s) and texture rate (320.0 GTexel/s vs 227.8 GTexel/s), which will benefit both gaming and rendering tasks.

The Pro W6600M’s advantage lies in its RDNA 2.0 architecture, which is a proven, mature design. It has been on the market since June 2021, while the RX 7700S launched in January 2023. While the Pro W6600M is now end-of-life, its driver maturity and compatibility with professional software ecosystems may still hold value for legacy workstation deployments. Its lower TDP of 90 W versus 100 W also makes it slightly more power-efficient in absolute terms, though the RX 7700S delivers far more performance per watt given its massive compute advantage.

For gaming, the RX 7700S is the obvious winner. Its 3DMark Steel Nomad DX12 score of 2,185, while not directly comparable to the Pro W6600M (which lacks this benchmark), demonstrates solid DirectX 12 performance. The Vulkan score of 85,603 further reinforces its gaming credentials. The Pro W6600M has no gaming-specific benchmark data in the pack, suggesting it is not the intended target for such workloads.

The Verdict

The data clearly favors the AMD Radeon RX 7700S for most use cases. Its 23.4% lead in Geekbench OpenCL, combined with nearly three times the FP32 compute throughput (20.48 TFLOPS vs 7.290 TFLOPS), makes it the superior choice for compute-intensive tasks. The RX 7700S also benefits from a newer architecture, higher clock speeds, and more memory bandwidth, all of which contribute to its performance advantage.

The RX 7700S is the pick for gamers and content creators who need maximum performance in a mobile form factor. Its 3DMark Steel Nomad score of 2,185 and Vulkan score of 85,603 indicate strong modern API support, and its 8 GB of GDDR6 memory is adequate for current titles at 1080p and 1440p. The Pro W6600M, with its end-of-life status and lower compute performance, is harder to recommend for new purchases.

However, the Pro W6600M still holds relevance in specific scenarios. Its RDNA 2.0 architecture is mature and well-supported in professional applications, and its lower 90 W TDP makes it suitable for thinner, more power-constrained laptops. For organizations with existing software certification for RDNA 2.0, the Pro W6600M may offer a stable, if slower, workstation solution. The RX 7700S, with its active production status and higher performance, represents a better long-term investment for most buyers.
