AMD Radeon RX 6750 XT vs AMD Radeon RX 6800M Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall winner in the head-to-head comparisons: the AMD Radeon RX 6750 XT takes 10 of the 11 benchmark tests, while the AMD Radeon RX 6800M manages a single victory. That lone win, however, is a massive one. In the Geekbench OpenCL test, the RX 6800M scores 87,621 against the RX 6750 XT's 16,360, a delta of 435.6% in favor of the mobile part. That is not a marginal edge; it is a dominant outlier that suggests the OpenCL workload favors the RX 6800M's configuration far more than any other test in the suite.

Outside of that anomaly, the RX 6750 XT is consistently ahead, though the margins vary sharply by workload. In 3DMark Steel Nomad DX12, the RX 6750 XT scores 2,548 versus 2,238, a 12.2% advantage. That is a moderate win in a modern DirectX 12 rasterization test. The Geekbench Metal test shows a larger gap: 137,249 for the RX 6750 XT against 113,721 for the RX 6800M, a 17.1% delta. The Vulkan result is much closer, with the RX 6750 XT at 98,089 and the RX 6800M at 94,766, a slim 3.4% lead. This suggests that in Vulkan-based titles the two parts are nearly interchangeable, whereas Metal and DX12 workloads give the desktop card a clearer edge.

The Passmark suite tells a similar story, but with wider spreads in some legacy tests. In Passmark DirectX 9, the RX 6750 XT posts 263 versus 147, a 44.1% lead. The DirectX 11 result is 180 versus 127, a 29.4% gap. DirectX 10 shows 125 versus 101, a 19.2% difference, and DirectX 12 shows 80 versus 65, an 18.7% gap. The Passmark G2D test, which measures 2D graphics performance, favors the RX 6750 XT by 44.7%, with scores of 972 and 538. The Passmark G3D result is 20,700 versus 13,261, a 35.9% advantage for the RX 6750 XT. The compute-oriented Passmark GPU Compute test shows the largest Passmark gap: 9,550 versus 5,032, a 47.3% delta.

Interpreting these numbers, the RX 6750 XT is the stronger part in almost every category the database measures. The only place the RX 6800M fights back is OpenCL, where its result is more than five times higher. For users targeting OpenCL-based applications, the RX 6800M is clearly the better choice. For everything else, the RX 6750 XT holds a meaningful, sometimes overwhelming, performance lead.

The Verdict

The data points to a straightforward conclusion: the AMD Radeon RX 6750 XT is the faster GPU in the vast majority of benchmark scenarios. Its wins in DirectX 9, 10, 11, and 12, plus Metal, Vulkan, G2D, G3D, and compute tests, make it the default pick for anyone whose workload spans standard graphics APIs. The 3DMark Steel Nomad result reinforces this, as the RX 6750 XT leads by 12.2% in a modern DX12 test. The Passmark G3D and GPU Compute margins of 35.9% and 47.3% respectively show that the desktop card is not just slightly ahead; it is substantially ahead in raw throughput.

The AMD Radeon RX 6800M should be chosen only when the OpenCL workload dominates. Its 435.6% advantage in Geekbench OpenCL is so large that it overrides the other results for that specific use case. Outside of that, the RX 6800M trails in every other recorded test, and its percentile ranking reflects this: it sits at the 74th percentile of all GPUs, while the RX 6750 XT sits at the 71st percentile. Interestingly, the RX 6800M has a higher average benchmark score of 28,874 compared to the RX 6750 XT's 26,011, but that average is heavily skewed by the OpenCL outlier. The nearest rival data confirms the positioning: the RX 6800M sits within 1% of parts like the AMD Radeon RX 570 and RX 470, while the RX 6750 XT sits within 1.1% of the NVIDIA GeForce RTX 3080 Ti Mobile. In practical terms, the RX 6750 XT competes at a higher performance tier.

For a gamer or general-purpose user, the RX 6750 XT is the safer and faster option. For an OpenCL-specific compute task, the RX 6800M is the only rational pick. There is no middle ground in the data.

Architecture Differences

Both GPUs are built on the same fundamental architecture. The chip is Navi 22 for both, and both use RDNA 2.0 with a 7 nm process from TSMC. The transistor count is identical at 17,200 million, and the die size is the same at 335 mm². The transistor density is also identical at 51.3M per mm². This means the underlying silicon is the same, and the performance differences come from clock speeds, power allocation, and the surrounding platform.

The RX 6800M belongs to the Navi Mobile (RX 6000M) generation, while the RX 6750 XT belongs to the Navi II (RX 6000) generation. Both have the same shading unit count of 2,560, the same 160 texture mapping units, the same 64 render output units, and the same 40 ray tracing cores. Neither has tensor cores. The DirectX support is identical at 12 Ultimate (12_2), and both support OpenGL 4.6 and Vulkan 1.4. The bus interface is PCIe 4.0 x16 for both.

The core difference in architecture, as far as the database records, is the clock profile. The RX 6800M has a base clock of 2116 MHz, a boost clock of 2390 MHz, and a game clock of 2300 MHz. The RX 6750 XT runs higher across the board: 2150 MHz base, 2600 MHz boost, and 2495 MHz game clock. The memory clocks also differ, with the RX 6800M at 2000 MHz (16 Gbps effective) and the RX 6750 XT at 2250 MHz (18 Gbps effective). Memory size, type, and bus width are identical: 12 GB of GDDR6 on a 192 bit bus.

The power envelope is where the two parts diverge most sharply. The RX 6800M is rated at 145 W TDP, while the RX 6750 XT is rated at 250 W. The RX 6800M uses no power connectors and is listed as an IGP (integrated graphics package) slot width, whereas the RX 6750 XT is a dual-slot card with 1x 6-pin plus 1x 8-pin power connectors and a suggested PSU of 600 W. The RX 6750 XT also has physical dimensions recorded at 267 mm length, 110 mm height, and 40 mm width, while the RX 6800M has no dimensions listed. Display outputs differ as well: the RX 6800M is portable device dependent, while the RX 6750 XT offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The release timing is also different. The RX 6800M was released on 2021-05-30, while the RX 6750 XT came later on 2022-03-02. Both are end-of-life products. The RX 6800M's predecessor is Polaris Mobile, while the RX 6750 XT's predecessor is Navi. The RX 6750 XT has a successor listed as Navi III, while the RX 6800M has none recorded.
