AMD Radeon RX 6650 XT vs AMD Radeon RX 7600S Comparison

Head-to-Head Benchmarks

The head-to-head data paints a surprisingly split picture, with the desktop-oriented RX 6650 XT taking the majority of wins but the mobile RX 7600S securing some notable victories. Out of ten recorded benchmarks, the RX 6650 XT claims seven wins, while the RX 7600S takes three.

The most striking result in the entire comparison is in Geekbench OpenCL, where the RX 7600S scores 68,012 against the RX 6650 XT's 10,111. That is a delta of 85.1 percent in favor of the mobile chip, an enormous margin that suggests the RX 7600S has a fundamentally different compute architecture or driver behavior in this specific workload. This is the single biggest gap between the two cards in either direction.

The RX 6650 XT counters with several decisive wins. In Passmark DirectX 10, it leads by 47.3 percent (109 versus 74). In Passmark DirectX 11, it is ahead by 20.7 percent (169 versus 140). The Geekbench Vulkan test shows a 10.1 percent advantage for the RX 6650 XT, with scores of 81,306 versus 73,868. PassMark G3D, the general 3D performance metric, favors the RX 6650 XT by 11.4 percent (17,166 versus 15,408). Compute workloads in PassMark show a 15.5 percent lead for the RX 6650 XT (7,532 versus 6,520).

The RX 7600S also wins the 3DMark Steel Nomad DX12 test, but by a narrow margin: 1,888 versus 1,859, a delta of 1.5 percent. It also takes PassMark DirectX 12 with 65 versus 62, a 4.6 percent edge. The older DirectX 9 workload is nearly a tie, with the RX 6650 XT at 215 and the RX 7600S at 211, a 1.9 percent difference.

In 2D performance, the RX 6650 XT is clearly stronger, scoring 918 in PassMark G2D against the RX 7600S's 776, an 18.3 percent lead. Overall, the data suggests the RX 6650 XT is the more consistent performer across the majority of tests, but the RX 7600S has a clear specialization in compute-heavy OpenCL workloads.

The Verdict

The data indicates a clear split in intended use cases. The AMD Radeon RX 6650 XT is the stronger all-around performer, winning seven of ten head-to-head benchmarks and holding a higher average score (19,765 versus 16,696). It leads in every PassMark graphics test except DirectX 12, and it wins in Vulkan and G3D. For most gaming and general 3D workloads, the RX 6650 XT is the better pick based on recorded scores.

The AMD Radeon RX 7600S, however, is the specialist. Its 85.1 percent lead in Geekbench OpenCL is the single most dominant result in the comparison. For compute tasks that rely on OpenCL, the RX 7600S is clearly superior. It also edges out the RX 6650 XT in 3DMark Steel Nomad DX12 and PassMark DirectX 12, suggesting it handles modern DX12 titles slightly better.

The RX 6650 XT sits in the 65th percentile of all GPUs, while the RX 7600S is in the 60th percentile. The difference in average benchmark score is roughly 18 percent in favor of the RX 6650 XT. Users prioritizing broad gaming and 3D performance should choose the RX 6650 XT. Users with compute-heavy OpenCL workloads should look at the RX 7600S.

Specification Differences

The two cards differ in several key specifications beyond their scores. The RX 6650 XT uses the Navi 23 chip and is part of the Radeon RX 6000 series, while the RX 7600S uses the Navi 33 chip and belongs to the Radeon RX 7000 series. The RX 6650 XT is a desktop card with a dual-slot design and a 1x 8-pin power connector, along with a suggested PSU of 450 W. The RX 7600S is an IGP (integrated graphics processor) for portable devices, has no power connectors, and its display outputs are described as portable device dependent.

Clock speeds are noticeably different. The RX 6650 XT has a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. The RX 7600S has a much lower base clock of 1500 MHz, a game clock of 1865 MHz, and a boost clock of 2200 MHz. The RX 6650 XT also has higher memory clocks at 2190 MHz (17.5 Gbps effective) versus 2000 MHz (16 Gbps effective) for the RX 7600S.

The RX 6650 XT has more shading units (2048 vs 1792), TMUs (128 vs 112), and ray tracing cores (32 vs 28). Both have 64 ROPs. The bus interface is also different: the RX 6650 XT uses PCIe 4.0 x8, while the RX 7600S uses PCIe 4.0 x16. The RX 6650 XT has a launch MSRP of 399 USD.

Architecture Difference

The architectural differences are significant. The RX 6650 XT is built on RDNA 2.0 architecture, while the RX 7600S uses RDNA 3.0. This is a generation leap in instruction set and execution. The RX 6650 XT is fabricated on a 7 nm process at TSMC, while the RX 7600S uses a smaller 6 nm process, also at TSMC. The smaller node allows the RX 7600S to pack 13,300 million transistors into a 204 mm² die, whereas the RX 6650 XT has 11,060 million transistors on a larger 237 mm² die. The transistor density is notably higher for the RX 7600S at 65.2M per mm² versus 46.7M per mm².

The RX 7600S is part of the Navi Mobile generation, with the codename "Hotpink Bonefish". The RX 6650 XT has no codename listed. The RX 7600S has a successor of Polaris Mobile, while the RX 6650 XT's successor is Navi III. The RX 6650 XT is end-of-life, while the RX 7600S is active in production. The RX 6650 XT was released in May 2022, and the RX 7600S in January 2023. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Pixel rate and texture rate are higher for the RX 6650 XT (168.6 GPixel/s, 337.3 GTexel/s) versus the RX 7600S (140.8 GPixel/s, 246.4 GTexel/s). The FP32 performance is the opposite: the RX 7600S has 15.77 TFLOPS versus the RX 6650 XT's 10.79 TFLOPS, and FP16 is 31.54 TFLOPS versus 21.59 TFLOPS.

Where Each One Wins

The RX 6650 XT wins in the majority of the recorded benchmarks. It is the stronger choice for DirectX 10, DirectX 11, DirectX 9, G2D, G3D, GPU Compute, and Vulkan workloads. In practical terms, this means it is the better performer for most traditional gaming, legacy API titles, and general 3D rendering. Its higher texture rate (337.3 GTexel/s) and pixel rate (168.6 GPixel/s) support its dominance in graphics-bound tasks. It also has a higher memory bandwidth (280.3 GB/s), which helps in texture-heavy scenarios.

The RX 7600S wins in Geekbench OpenCL, where it is exceptionally fast, and in 3DMark Steel Nomad DX12 and PassMark DirectX 12. This indicates a specific strength in compute-heavy OpenCL workloads and in modern DirectX 12 titles. Its higher FP32 and FP16 throughput (15.77 and 31.54 TFLOPS, respectively) likely explain its OpenCL advantage. The RX 7600S also benefits from the smaller 6 nm node and higher transistor density, but the data shows that raw compute throughput does not always translate to higher scores in all APIs.

In summary, the RX 6650 XT is the more versatile and consistent performer across the board, while the RX 7600S is a specialist in compute and specific modern APIs.
