AMD Radeon PRO W7600 vs AMD Radeon RX 6650M XT Comparison

AMD Radeon PRO W7600 vs AMD Radeon RX 6650M XT: the former is a desktop workstation card built on RDNA 3.0, while the latter is a mobile gaming GPU based on RDNA 2.0. Benchmark data shows a single head-to-head result, with the PRO W7600 taking the win, but the two cards serve fundamentally different purposes that the raw scores only partially capture.

Where Each One Wins

The AMD Radeon PRO W7600 wins the only direct benchmark comparison available: Geekbench OpenCL. In that test, it scores 81528 against the RX 6650M XT’s 76904, a 6% advantage. This is the sole head-to-head data point, so the Win count is 1 for the PRO W7600 and 0 for the RX 6650M XT. The PRO W7600 also holds a higher average benchmark score of 87108 versus 76904, which places it in the 93rd percentile of all GPUs; the RX 6650M XT sits in the 91st percentile. While the delta is modest, the PRO W7600’s positioning in the 93rd percentile indicates it ranks above roughly 93% of the entire GPU population, whereas the RX 6650M XT ranks above 91%.

The RX 6650M XT’s wins are not found in benchmark scores but in its intended usage context. It is an integrated graphics processor (IGP) for mobile devices, with no dedicated power connectors and a 120 W TDP. Its display outputs are listed as “Portable Device Dependent,” meaning it is designed to be embedded in laptops. The PRO W7600, by contrast, is a single-slot desktop card with a 6-pin power connector and four DisplayPort 2.1 outputs. For workloads requiring a fixed workstation setup with multiple monitors, the PRO W7600 is the obvious choice. For mobile deployment where power draw and physical footprint are constrained, the RX 6650M XT is the only viable option of the two.

FAQ

A: The PRO W7600 has 13,300 million transistors on a 204 mm² die, resulting in a density of 65.2M / mm². The RX 6650M XT has 11,060 million transistors on a larger 237 mm² die, yielding a lower density of 46.7M / mm².

Q: Do both GPUs have the same memory configuration?

A: Both have 8 GB of GDDR6 memory on a 128-bit bus, but the PRO W7600 has higher memory clock (2250 MHz, 18 Gbps effective) and bandwidth (288.0 GB/s) compared to the RX 6650M XT’s 2000 MHz (16 Gbps effective) and 256.0 GB/s.

Q: What is the production status of each GPU?

A: The PRO W7600 is listed as “Active,” while the RX 6650M XT is “End-of-life.” The PRO W7600 was released on 2023-08-02, and the RX 6650M XT on 2022-01-03.

Head-to-Head Benchmarks

The sole head-to-head benchmark is Geekbench OpenCL. The AMD Radeon PRO W7600 scores 81528, while the AMD Radeon RX 6650M XT scores 76904. The delta is 6%, meaning the PRO W7600 is 6% faster in this workload. This is a modest margin, but it is consistent with the PRO W7600’s higher average benchmark score of 87108 versus 76904.

The PRO W7600 also has a Geekbench Vulkan score of 92688, though the RX 6650M XT has no corresponding Vulkan result in the data pack. That Vulkan score is notably higher than the PRO W7600’s own OpenCL result, suggesting the PRO W7600’s compute performance varies by API. However, without an RX 6650M XT Vulkan score, no cross-GPU comparison can be made for that test.

When looking at the PRO W7600’s nearest rivals, its average score of 87108 sits within a narrow band: it is 0.4% behind the NVIDIA Quadro GP100 (87445), 1.7% ahead of the NVIDIA CMP 40HX (85637), 4.4% behind the NVIDIA RTX A4500 Mobile (91134), and 5% behind the NVIDIA RTX A4500 (91671). This places the PRO W7600 in the same performance tier as those professional cards. The RX 6650M XT’s nearest rivals show a different picture: it is 1% behind the NVIDIA GeForce RTX 5090 D (77712), 2.6% behind the AMD Radeon RX 6850M XT (78940), 3.1% behind the NVIDIA Tesla P100 PCIe 12 GB (79396), and 3.4% behind the NVIDIA Tesla P100 PCIe 16 GB (79605). The RX 6650M XT’s competitive set is thus slightly higher-performing on average, but the PRO W7600 still wins the direct comparison.

Specification Differences

The two GPUs differ across nearly every specification field. The PRO W7600 uses a 6 nm process node, while the RX 6650M XT uses 7 nm. Transistor counts are 13,300 million versus 11,060 million, and die sizes are 204 mm² versus 237 mm². Transistor density is 65.2M / mm² for the PRO W7600 and 46.7M / mm² for the RX 6650M XT.

Clock speeds differ significantly. The PRO W7600 has a base clock of 1720 MHz and a boost clock of 2440 MHz, with no game clock listed. The RX 6650M XT has a higher base clock of 2068 MHz, a boost clock of 2416 MHz, and a game clock of 2162 MHz. Memory clocks also differ: 2250 MHz (18 Gbps effective) for the PRO W7600 versus 2000 MHz (16 Gbps effective) for the RX 6650M XT. This results in bandwidth of 288.0 GB/s versus 256.0 GB/s, despite both having 8 GB GDDR6 on a 128-bit bus.

The PRO W7600 has a TDP of 130 W, requires a 1x 6-pin power connector, and a 300 W suggested PSU. The RX 6650M XT has a 120 W TDP, no power connectors, and no suggested PSU. The PRO W7600 is single-slot with dimensions of 241 mm (9.5 inches) in length and 115 mm (4.5 inches) in height; the RX 6650M XT is an IGP with no dimensions listed. Display outputs are 4x DisplayPort 2.1 for the PRO W7600 versus “Portable Device Dependent” for the RX 6650M XT.

Architecture Differences

The architectural gap is generational. The PRO W7600 is built on RDNA 3.0, while the RX 6650M XT is RDNA 2.0. The PRO W7600’s chip is Navi 33, codenamed “Hotpink Bonefish,” and belongs to the “Radeon Pro Navi (Navi III Series)” generation. The RX 6650M XT uses Navi 23 from the “Navi Mobile (RX 6000M)” generation. Both are fabricated by TSMC, but on different nodes (6 nm vs 7 nm).

Both GPUs have identical core counts: 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. Neither has tensor cores. Pixel rates are nearly identical: 156.2 GPixel/s for the PRO W7600 and 154.6 GPixel/s for the RX 6650M XT. Texture rates are 312.3 GTexel/s versus 309.2 GTexel/s.

The biggest architectural split is in compute throughput. The PRO W7600 delivers 19.99 TFLOPS FP32 and 39.98 TFLOPS FP16 (2:1), while the RX 6650M XT delivers 9.896 TFLOPS FP32 and 19.79 TFLOPS FP16 (2:1). That is roughly a 2x difference in raw compute, which explains the PRO W7600’s higher benchmark scores despite similar core counts. The PRO W7600’s higher transistor density (65.2M / mm² vs 46.7M / mm²) reflects the more advanced 6 nm process.

The RX 6650M XT has a higher base clock (2068 MHz) than the PRO W7600 (1720 MHz), which partially compensates for its older architecture, but the PRO W7600’s boost clock (2440 MHz) is slightly higher than the RX 6650M XT’s (2416 MHz). The PRO W7600 also has a predecessor in the Radeon Pro Vega series, whereas the RX 6650M XT’s predecessor is Polaris Mobile. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data points to a clear choice for workstation use: the AMD Radeon PRO W7600. It wins the only head-to-head benchmark by 6%, has a higher average score (87108 vs 76904), and sits in the 93rd percentile versus the RX 6650M XT’s 91st. Its 19.99 TFLOPS FP32 performance is double the RX 6650M XT’s 9.896 TFLOPS, and it offers 288.0 GB/s memory bandwidth over 256.0 GB/s. It is an active product with a defined launch MSRP of 599 USD, a single-slot form factor, and four DisplayPort 2.1 outputs, making it suitable for professional multi-display environments.

The RX 6650M XT is a mobile part, end-of-life, with no MSRP listed. Its higher base clock (2068 MHz) does not compensate for the older RDNA 2.0 architecture or the 2x FP32 deficit. Its only advantages are a lower TDP (120 W vs 130 W) and the absence of external power connectors, which are irrelevant for desktop use. The RX 6650M XT’s nearest rivals include high-end NVIDIA parts like the RTX 5090 D and Tesla P100, but it trails all of them by 1% to 3.4%, showing it is positioned at the lower end of its performance tier.

For a user needing a desktop workstation GPU with validated professional drivers, the PRO W7600 is the data-backed selection. For a mobile laptop implementation, the RX 6650M XT is the only one of the two that fits, but its performance is measurably lower. The PRO W7600 wins on compute, bandwidth, architecture, and production status; the RX 6650M XT wins on portability and power efficiency. In every benchmark where both have data, the PRO W7600 leads.
