AMD Radeon RX 6700S vs AMD Radeon RX 6750 XT Comparison

The Verdict

The data presents a clear hierarchy: the AMD Radeon RX 6750 XT is the decisive winner in nearly every recorded benchmark, taking 10 of 11 head-to-head tests. Its average benchmark score of 26,011 places it at the 71st percentile of all GPUs, while the RX 6700S averages 22,154, sitting at the 67th percentile. For desktop users building a performance-oriented rig, the RX 6750 XT is the obvious choice based on raw output, offering substantial leads in DirectX 12, Vulkan, and compute workloads.

The AMD Radeon RX 6700S, however, is not without a niche. Its one head-to-head victory, a massive 76.9% lead in Geekbench OpenCL, suggests it has a specific strength in OpenCL compute environments. Furthermore, its 80 W TDP and IGP slot width indicate a fundamentally different design target. The RX 6750 XT requires a 250 W TDP, a dual-slot cooler, and a 600 W suggested PSU, plus one 6-pin and one 8-pin power connector. The RX 6700S, by contrast, draws no external power connectors and is classified as an IGP, pointing toward compact, portable devices. Users needing a power-sipping solution for thin laptops should favor the RX 6700S; users prioritizing frame rates in games will gravitate to the RX 6750 XT.

Architecture Differences

Both GPUs share the same RDNA 2.0 architecture, manufactured on TSMC's 7 nm process, and both support DirectX 12 Ultimate (12_2), OpenGL 4.0, and Vulkan 1.4. The silicon differences are significant. The RX 6750 XT uses the Navi 22 chip with a die size of 335 mm², housing 17,200 million transistors at a transistor density of 51.3M per mm². The RX 6700S uses the Navi 23 chip, a smaller 237 mm² die with 11,060 million transistors at 46.7M per mm². This translates to a large compute gap at the core level.

The RX 6750 XT features 2,560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. It runs at a base clock of 2,150 MHz, a game clock of 2,495 MHz, and boosts to 2,600 MHz. Memory states include 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s bandwidth. Compute output is rated at 13.31 TFLOPS FP32 and 26.62 TFLOPS FP16 (2:1), with texture rate at 416.0 GTexel/s and pixel rate at 166.4 GPixel/s.

The RX 6700S is more modest. It has 1,792 shading units, 112 TMUs, and 64 ROPs, with 28 ray tracing cores. Clocks are lower: 1,700 MHz base, 1,890 MHz game, 2,000 MHz boost. It uses 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s. Compute is 7.168 TFLOPS FP32 and 14.34 TFLOPS FP16 (2:1). Its texture rate is 224.0 GTexel/s and pixel rate is 128.0 GPixel/s. The RX 6750 XT also uses a PCIe 4.0 x16 interface, while the RX 6700S uses a x8 interface. Display outputs differ too: the 6750 XT offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the 6700S is listed as portable device dependent.

Where Each One Wins

The RX 6750 XT dominates in traditional graphics workloads. It wins the 3DMark Steel Nomad DX12 test by 75.6% (2,548 vs 1,451), which is a strong indicator for modern game performance under DirectX 12. It also leads in Vulkan by 28.8% (98,089 vs 76,150). In legacy DirectX tests, the wins are consistent: DirectX 10 by 43.7% (125 vs 87), DirectX 11 by 34.3% (180 vs 134), DirectX 12 by 37.9% (80 vs 58), and DirectX 9 by 34.9% (263 vs 195). The 6750 XT is also ahead in the Passmark G3D score by 37.4% (20,700 vs 15,066) and in GPU compute by 59.4% (9,550 vs 5,990). Its Geekbench Metal score is 88.4% higher (137,249 vs 72,864), and even in 2D tests it leads by 31.5% (972 vs 739).

The RX 6700S has one clear area of superiority: Geekbench OpenCL, where it scores 70,965 versus 16,360, a 76.9% advantage. This is a notable outlier, indicating that in OpenCL compute tasks, the 6700S may be the better performer. Everything else points to the RX 6750 XT for gaming and general compute.

Head-to-Head Benchmarks

The biggest win for the RX 6750 XT is in Geekbench Metal, where it scores 137,249 against 72,864, a 88.4% delta. This is a strong signal for macOS-style Metal workloads or any application using that API. The second-largest margin is in 3DMark Steel Nomad DX12, at 75.6% (2,548 vs 1,451). This test is a modern, demanding DX12 benchmark, and the 6750 XT nearly doubles the 6700S output.

In Passmark GPU compute, the 6750 XT is 59.4% ahead (9,550 vs 5,990), showing clear superiority in general-purpose compute. The Vulkan test shows a 28.8% lead (98,089 vs 76,150), which is relevant for cross-platform games and Vulkan-based applications. In the DirectX legacy tests, the margins are consistent: 43.7% in DirectX 10, 34.3% in DirectX 11, 37.9% in DirectX 12, and 34.9% in DirectX 9. The Passmark G3D score, a broad gaming metric, is 37.4% higher (20,700 vs 15,066). Even the 2D test shows a 31.5% lead (972 vs 739).

The lone RX 6700S victory in Geekbench OpenCL is dramatic: 70,965 vs 16,360, a 76.9% delta. This is an unusual result, and it suggests that the 6700S may have a specialized compute pipeline for OpenCL that the 6750 XT lacks, or that the benchmark conditions favor the mobile GPU. Regardless, it is the only data point where the 6700S wins.

Overall, the head-to-head data is one-sided. The RX 6750 XT wins 10 of 11 tests, with a weighted average benchmark score of 26,011 versus 22,154. Its nearest rivals in the database include the AMD Radeon R9 M395X (0.5% delta), AMD FirePro W7100 (0.6% delta), AMD FirePro D700 (0.7% delta), and NVIDIA GeForce RTX 3080 Ti Mobile (1.1% delta). The RX 6700S, by contrast, sits near the AMD Radeon RX 5700 (0.1% delta), NVIDIA GeForce RTX 5060 Mobile (1.3% delta), NVIDIA GeForce GTX 1060 6 GB (1.4% delta), and AMD Radeon RX 7700 XT (1.7% delta), suggesting it competes at a lower performance tier.
