AMD Radeon RX 7600M vs AMD Radeon RX 7800M Comparison

The AMD Radeon RX 7800M and AMD Radeon RX 7600M are both active RDNA 3.0 mobile parts from the Navi Mobile (RX 7000M) generation, yet the benchmark data positions them very differently. The RX 7800M, built on the Navi 32 chip, delivers a commanding lead in the only shared test, while the RX 7600M, using the smaller Navi 33 chip, holds a higher average benchmark score due to a single strong submission. The two GPUs share the same DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 API support, but diverge sharply in core configuration, memory subsystem, and power envelope.

The Verdict

The data points to the AMD Radeon RX 7800M for users prioritizing raw compute and memory bandwidth in heavy workloads. Its Geekbench OpenCL score of 121,647 is 91.6% higher than the RX 7600M’s 63,505, a near-doubling of performance that reflects its larger silicon. The RX 7800M also shows a 3DMark Steel Nomad DX12 score of 3,073, a result not available for the RX 7600M, suggesting stronger modern API gaming potential. However, the RX 7600M’s average benchmark score of 63,505 sits 1.8% above the RX 7800M’s 62,360, which is a statistical artifact of the latter’s two-test average versus the former’s single result. Pick the RX 7800M if the workload demands peak FP32 throughput and 12 GB of VRAM; pick the RX 7600M if the goal is a lower-power, 90 W part that still lands in the 90th percentile of all GPUs. The RX 7600M’s nearest rival list includes the AMD Radeon VII at -1.3% and NVIDIA CMP 30HX at -1%, indicating it trades blows with older high-end parts, while the RX 7800M sits just 0.4% above the AMD Radeon 8050S and 1.4% above the RX 6850M XT.

Architecture Differences

The two GPUs share the RDNA 3.0 architecture and TSMC as the foundry, but the process node and die design separate them. The RX 7800M uses a 5 nm process with a 346 mm² die containing 28,100 million transistors, yielding a transistor density of 81.2M per mm². The RX 7600M steps down to a 6 nm process on a 204 mm² die with 13,300 million transistors, for a density of 65.2M per mm². This nearly 15.9% density advantage for the RX 7800M comes from the smaller node and reflects a more complex chip. The RX 7800M’s Navi 32 chip carries 3,840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores, while the RX 7600M’s Navi 33 halves those counts to 1,792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. Neither part has tensor cores. The clock behavior differs: the RX 7600M has a higher base clock at 1500 MHz versus 1295 MHz, and a higher boost at 2410 MHz versus 2335 MHz, but the RX 7800M’s game clock of 2145 MHz edges out the 2070 MHz of the smaller chip. The RX 7800M compensates with wider execution resources, producing 35.87 TFLOPS FP32 versus 17.27 TFLOPS for the RX 7600M, and FP16 rates of 71.73 TFLOPS versus 34.55 TFLOPS, both at 2:1 ratio.

Head-to-Head Benchmarks

The only direct comparison available is Geekbench OpenCL, and the result is decisive. The RX 7800M scores 121,647 against the RX 7600M’s 63,505, a delta of 91.6% in favor of the larger GPU. This margin dwarfs the differences seen in the rival lists: the RX 7800M’s closest rival, the AMD Radeon 8050S, is only 0.4% behind its average score of 62,360, and the RX 6850M XT trails by 1.4%. The RX 7600M, by contrast, leads the RX 7800M by 1.8% in average benchmark score, but that figure is misleading because the RX 7600M’s average is its single OpenCL result (63,505), while the RX 7800M’s average blends the 121,647 OpenCL score with the 3,073 Steel Nomad result. In the head-to-head, the RX 7800M wins the sole benchmark with a 91.6% lead, and the wins tally is 1 for the RX 7800M and 0 for the RX 7600M. The RX 7800M’s 3DMark Steel Nomad DX12 score of 3,073 has no counterpart in the RX 7600M’s data, so no delta can be computed, but its presence indicates the RX 7800M was tested in a modern DX12 workload where the RX 7600M has no recorded result.

FAQ

Where Each One Wins

The RX 7800M wins in raw compute throughput, as evidenced by its 35.87 TFLOPS FP32 versus 17.27 TFLOPS for the RX 7600M, and its 91.6% lead in Geekbench OpenCL. It also wins in memory capacity and bandwidth, with 12 GB and 432.0 GB/s against 8 GB and 256.0 GB/s, making it the choice for texture-heavy or large-dataset workloads. The RX 7800M’s higher pixel rate of 224.2 GPixel/s and texture rate of 560.4 GTexel/s, compared to 154.2 GPixel/s and 269.9 GTexel/s for the RX 7600M, further favor it in rasterization-heavy scenes. The RX 7600M wins in efficiency, with a 90 W TDP that is half the 180 W of the RX 7800M, and it holds a higher average benchmark score of 63,505 versus 62,360. In the rival context, the RX 7800M sits just above the RX 6850M XT and 8050S, while the RX 7600M outperforms the Radeon VII and CMP 30HX, indicating the smaller chip competes with older flagship desktop parts in compute despite its lower core count. For the RX 7800M, the 3DMark Steel Nomad score of 3,073 provides a DX12 data point that the RX 7600M lacks, suggesting the larger GPU is better suited to modern API workloads.
