AMD Radeon RX 6650M vs NVIDIA A10M Comparison

The Verdict

The NVIDIA A10M is the decisive performance leader in this comparison. The recorded data shows a single head-to-head benchmark, Geekbench OpenCL, where the A10M scores 135,230 against 65,800 for the AMD Radeon RX 6650M. That is a 105.5% advantage, meaning the A10M more than doubles the RX 6650M's compute output in this test. The verdict is straightforward: if compute throughput is the priority, the A10M is the only choice from these two.

The AMD Radeon RX 6650M is not without purpose, but it wins in no measured benchmark. It sits in the 91st percentile of all GPUs, which is strong, yet the A10M sits in the 96th percentile. The A10M also has a higher average benchmark score of 135,230 versus 71,768 for the RX 6650M. The gap is not marginal; it is a full tier of performance separation.

Who should pick which? The A10M is for workloads where raw OpenCL compute, large memory capacity, and server-oriented features matter. The RX 6650M is for portable systems where power draw, physical integration, and display output flexibility are the constraints. Neither price nor value is considered here, only the recorded specifications and benchmark results.

Where Each One Wins

The A10M wins the only recorded benchmark, Geekbench OpenCL, with a score of 135,230. That places it 105.5% ahead of the RX 6650M in the same test. The A10M also wins on memory capacity, offering 20 GB against 8 GB, and on memory bandwidth, delivering 500.2 GB/s versus 224.0 GB/s. Those are not small differences; they change what workloads are feasible.

The RX 6650M wins in no benchmark, but it does win in physical and electrical characteristics. It has a lower TDP of 120 W versus 150 W for the A10M, and it is classified as an IGP, meaning it is designed for integration into a portable device. The A10M is a single-slot card with an 8-pin EPS power connector and no display outputs. The RX 6650M has display outputs marked as portable device dependent, and it requires no power connectors. For a laptop or compact mobile system, the RX 6650M is the only viable option.

The A10M also wins on raw shader count, with 7,168 shading units against 1,792 for the RX 6650M. It has 224 texture mapping units versus 112, and 80 render output units versus 64. The A10M's FP32 throughput is 23.44 TFLOPS, while the RX 6650M manages 8.659 TFLOPS. In FP16, the A10M also delivers 23.44 TFLOPS at a 1:1 ratio, while the RX 6650M delivers 17.32 TFLOPS at a 2:1 ratio. The A10M wins on raw compute, but the RX 6650M is more efficient per watt in FP16 relative to its FP32 output.

Architecture Differences

The NVIDIA A10M is built on the GA102 chip using the Ampere architecture, manufactured on an 8 nm process at Samsung.
