AMD Radeon PRO W7700 vs AMD Radeon RX 6650M XT Comparison

# AMD Radeon PRO W7700 vs AMD Radeon RX 6650M XT

The benchmark database places the AMD Radeon PRO W7700 and the AMD Radeon RX 6650M XT in different market segments with different architectural goals. The PRO W7700 is a professional workstation card built on the RDNA 3.0 architecture, while the RX 6650M XT is a mobile gaming GPU from the RDNA 2.0 generation. The recorded data shows a clear split: the W7700 wins the head-to-head benchmark, and the RX 6650M XT wins the overall efficiency discussion. This analysis breaks down where each card leads based on the recorded measurements.

Where Each One Wins

The head-to-head benchmark in the database contains exactly one test, Geekbench OpenCL. The AMD Radeon PRO W7700 wins that test with a score of 108,245 against 76,904 for the RX 6650M XT, a 40.8% advantage. That is the only direct comparison recorded, so the PRO W7700 takes the single head-to-head win.

The RX 6650M XT, however, is not without its own territory. The database shows the RX card has a 91st percentile rank versus all GPUs, meaning it performs better than 91% of all recorded GPUs. The PRO W7700 sits at a 95th percentile rank, a slightly higher standing in the overall database. The RX 6650M XT has its own benchmark result in Geekbench OpenCL with a score of 76,904, while the PRO W7700 records 108,245 in the OpenCL test and 129,706 in the Vulkan test.

When looking at the recorded wins, the PRO W7700 takes the head-to-head, but the RX 6650M XT has a lower average benchmark score and a lower percentile, making the PRO W7700 the stronger card in raw compute performance. The RX 6650M XT, on the other hand, is the only one of the two with a mobile form factor, which is a decisive factor for certain system builds.

Architecture Differences

The two GPUs come from different points in AMD's architecture timeline. The PRO W7700 is built on the Navi 32 chip with the RDNA 3.0 architecture, using the "Wheat Nas" codename, and belongs to the Radeon Pro Navi (Navi III Series) generation. It is fabricated on a 5 nm process at TSMC and packs 28,100 million transistors on a 346 mm² die, for a transistor density of 81.2 million per square mm. The RX 6650M XT is based on the Navi 23 chip with the RDNA 2.0 architecture, has no codename assigned, and belongs to the Navi Mobile (RX 6000M) generation. It uses a 7 nm process at TSMC and contains 11,060 million transistors on a 237 mm² die, for a density of 46.7 million per square mm.

Memory configurations are a major differentiator. The PRO W7700 ships with 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The RX 6650M X comes with 8 GB of GDDR6, a 128-bit bus, and a 256.0 GB/s memory bandwidth. The PRO card's clock speeds include a 1900 MHz base, 2600 MHz boost, and 2250 MHz memory. The RX M XT has a 2068 MHz base, 2416 MHz boost, 2162 MHz game clock, and 2000 MHz memory.

Compute resources are also skewed. The PRO W7700 has 3072 shading units, 192 texture mapping units, 96 ROPs, and 48 ray tracing cores. The RX 6650M XT has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The PRO part also carries 31.95 TFLOPS of FP32 and 63.90 TFLOPS of FP16 (2:1). The RX XT offers 9.896 TFLOPS FP32 and 19.79 TFLOPS FP16 (2:1). The PRO card has a 190 W TDP and uses a dual-slot cooler with a single 8-pin power connector. The RX 6650M XT is an integrated GPU with no power connectors and unspecified PSU requirements. The PRO connects via PCIe 4.0 x16, and the RX via PCIe 4.0 x8.

Head-to-Head Benchmarks

The only recorded head-to-head result is the Geekbench OpenCL test. The Radeon PRO W7700 scores 108,245, and the Radeon RX 6650M XT scores 76,904. That is a 40.8% win for the PRO card. The discrepancy is massive: the workstation card generates well over a third more compute throughput in this workload.

Looking at the broader benchmarks, the PRO W7700 reaches an average benchmark score of 118,976 in the database, while the RX 6650M XT averages 76,904. The PRO card sits at the 95th percentile of all GPUs while the RX sits at the 91st percentile. The average score difference places the PRO card well ahead.

The nearest rivals in the data for the PRO W7700 are the NVIDIA GB (117,393, 1.3% higher), the NVIDIA RTX 4000 SFF Ada Generation (117,088, 1.6% higher), the NVIDIA Tesla V100 SXM2 16 GB (114,395, 4% higher), and the NVIDIA RTX A5500 Mobile (113,944, 4.4% higher). The RX 6650M XT's closest recorded neighbors are the NVIDIA GeForce RTX 5090 D (77,712, 1% lower), the AMD Radeon RX 6850M XT (78,940, 2.6% lower), the NVIDIA Tesla P100 (79,396, 3.1% lower), and the NVIDIA Tesla P100 PCIe 16 GB (79,605, 3.4% lower). These percentages show that the RX 6650M XT is not far from a group of high-end cards, but the PRO W7700 is in a higher performance bracket.

The Verdict

From the database, the AMD Radeon PRO W7700 is the card to choose when compute performance is the priority. It wins the only head-to-head with a 40.8% score, has a higher average benchmark (118,976 versus 76,904), and has a higher percentile rank (95% vs 91%). It also has twice the memory capacity (16 GB versus 8 GB) and a much larger memory bus (256-bit vs 128-bit), which matters in memory-heavy workloads. Its extra compute resources (3072 shading units, 192 TMUs, 96 ROPs, 48 RT cores) versus the RX 6650M XT (2048 shading units, 128 TMUs, 64 ROPs, 32 RT cores) give it a measurable throughput advantage.

The AMD Radeon RX 6650M XT, however, remains a valid option for anyone who needs an iGPU with no external power connectors. It draws power solely from the slot, which makes it simpler to integrate into an existing mobile system. It also carries a lower die size (237 mm² vs 346 mm²), which may be important in space-constrained designs. But on pure compute performance, the PRO W7700 is the clear winner, and it is the recommended pick for anyone whom the benchmark results are the prime metric.
