Architecture Differences

The AMD Radeon PRO W7800 is built on the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito, fabricated on TSMC's 5 nm process. It belongs to the Radeon Pro Navi III Series generation. In contrast, the AMD Radeon RX 6650M uses the older RDNA 2.0 architecture with the Navi 23 chip, fabricated on TSMC's 7 nm process, and is part of the Navi Mobile RX 6000M generation. The process node difference (5 nm versus 7 nm) is a key architectural differentiator, and the transistor counts reflect this gap: the W7800 packs 57,700 million transistors on a 529 mm² die, giving a density of 109.1M per mm², while the RX 6650M has 11,060 million transistors on a 237 mm² die, for a density of 46.7M per mm².

The W7800 has 4,480 shading units, 280 texture mapping units, and 128 ROPs, with 70 ray tracing cores. The RX 6650M has 1,792 shading units, 112 TMUs, and 64 ROPs, with 28 ray tracing cores. That means the W7800 has 2.5 times the shading units, 2.5 times the TMUs, and exactly double the ROPs, with 2.5 times the ray tracing cores. The compute output is dramatically different: the W7800 delivers 45.25 TFLOPS FP32 and 90.50 TFLOPS FP16 (2:1), while the RX 6650M delivers 8.659 TFLOPS FP32 and 17.32 TFLOPS FP16 (2:1). The W7800 is roughly 5.2 times faster in raw FP32 throughput.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical. However, the W7800 has a PCIe 4.0 x16 interface, while the RX 6650M has a PCIe 4.0 x8 interface. The W7800's display outputs include 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, whereas the RX 6650M's display outputs are listed as "Portable Device Dependent," reflecting its mobile nature. The W7800 is a dual-slot desktop card with dimensions of 280 mm length, 110 mm height, and 40 mm width, while the RX 6650M has no recorded dimensions because it is an integrated GPU (IGP) for laptops.

The production statuses differ too: the W7800 is Active, while the RX 6650M is End-of-life. The W7800 was released on 2023-04-12, and the RX 6650M was released on 2022-01-03. The W7800's predecessor is the Radeon Pro Vega, while the RX 6650M's predecessor is Polaris Mobile. Neither has a recorded successor.

Head-to-Head Benchmarks

The database records two head-to-head benchmark comparisons between the AMD Radeon PRO W7800 and the AMD Radeon RX 6650M, both of which the W7800 wins decisively.

In Geekbench OpenCL, the W7800 scores 154,366 against 65,800 for the RX 6650M, yielding a delta of 134.6% in favor of the W7800. This is the larger of the two gaps. The OpenCL test exercises general-purpose compute, and the W7800's 45.25 TFLOPS FP32 versus the RX 6650M's 8.659 TFLOPS explains the magnitude of the lead. The W7800's 32 GB memory and 576.0 GB/s bandwidth also help in memory-bound OpenCL workloads, compared to the RX 6650M's 8 GB and 224.0 GB/s.

In Geekbench Vulkan, the W7800 scores 175,422 against 77,735 for the RX 6650M, a delta of 125.7% in favor of the W7800. The Vulkan test is more graphics-oriented, and the W7800's higher pixel rate (323.2 GPixel/s versus 154.6 GPixel/s) and texture rate (707.0 GTexel/s versus 270.6 GTexel/s) contribute to its advantage. The W7800 also has 70 RT cores versus 28, which helps in Vulkan ray tracing workloads.

The W7800's average benchmark score of 164,894 sits in the 97th percentile of all GPUs, while the RX 6650M's 71,768 average sits in the 91st percentile. In the nearest rivals list, the W7800 is nearly tied with the NVIDIA RTX A5500 (165,217 average, -0.2% delta) and the NVIDIA RTX 4500 Ada Generation (166,094, -0.7%), and it is 1.5% ahead of the NVIDIA A100 PCIe 40 GB (162,504) and 2.2% behind the AMD Radeon Pro W6900X (168,574). The RX 6650M, on the other hand, is nearly tied with the NVIDIA TITAN X Pascal (72,098, -0.5%) and the AMD Radeon Pro Vega 64 (72,379, -0.8%), while being 1.3% ahead of the AMD Radeon RX 6600 LE (70,829) and 2.2% behind the AMD Radeon Vega Frontier Edition (73,370).

The wins tally is 2 for the W7800 and 0 for the RX 6650M across all measured benchmarks. There is no recorded benchmark where the RX 6650M comes out ahead. The W7800's advantage spans both compute (OpenCL) and graphics (Vulkan) APIs, indicating that the performance gap is not workload-specific but rather a reflection of the fundamental architectural and specification differences. The W7800 is a larger, more powerful desktop workstation GPU with 5 times the transistors, 4 times the memory, and 5.2 times the FP32 throughput, while the RX 6650M is a compact mobile GPU with a 120 W TDP and no external power connectors. For any user choosing between these two based on raw performance, the W7800 is the only option that delivers professional-grade results, though the RX 6650M remains relevant for thin-and-light gaming laptops where power efficiency and portability take priority over absolute performance.
