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

AMD Radeon RX 6750 XT and AMD Radeon RX 6700M share the same Navi 22 chip and RDNA 2.0 architecture, but they are tuned for very different environments—one is a dual-slot desktop card, the other an integrated mobile GPU. The benchmark data shows a decisive overall victory for the desktop part, which wins 10 of 11 head-to-head tests, yet the mobile chip’s single win is so dramatic that it reshapes how these two should be evaluated. Both cards sit at the 71st percentile against all GPUs, and their average benchmark scores are remarkably close—26011 for the 6750 XT versus 25633 for the 6700M—but that closeness masks wildly different performance profiles across individual workloads.

Head-to-Head Benchmarks

The RX 6750 XT dominates the majority of the head-to-head comparisons, often by massive margins. In Passmark’s GPU compute test, the desktop card scores 9550 against the mobile part’s 5191, a delta of 84%—the largest gap in the entire dataset. Similarly, the Passmark G2D test shows a 75.1% advantage (972 vs 555), and the DirectX 9 test delivers a 69.7% lead (263 vs 155). These are not subtle differences; the 6750 XT is performing at a fundamentally higher level in legacy and compute-oriented workloads.

The 3DMark Steel Nomad DX12 test reinforces that pattern, with the 6750 XT scoring 2548 versus 1845 for the 6700M, a 38.1% win. Passmark DirectX 11 shows a 39.5% edge (180 vs 129), and DirectX 10 comes in at 35.9% (125 vs 92). Even in the newer DirectX 12 path, the desktop card leads by 23.1% (80 vs 65). The Geekbench Metal test is another standout: 137249 for the 6750 XT against 91911 for the 6700M, a 49.3% advantage. The Vulkan result is closer but still favors the desktop part, 98089 versus 90816, an 8% gap. The Passmark G3D score, often considered a broad gaming indicator, lands at 20700 for the 6750 XT versus 13536 for the 6700M, a 52.9% lead.

The single exception is Geekbench OpenCL, where the 6700M posts 77666 against the 6750 XT’s 16360. That is a 78.9% victory for the mobile chip, and it is the only test where the 6700M wins. The magnitude of that win is striking—the 6700M scores nearly 4.7 times higher than the 6750 XT in this specific workload. This outlier suggests that the mobile part’s driver optimizations or memory configuration produce an unusually strong result in OpenCL compute, even though its raw specifications are lower across the board.

Looking at the averages, the 6750 XT’s overall benchmark score of 26011 is only 1.5% higher than the 6700M’s 25633, despite the lopsided head-to-head record. The nearest rivals for each card reinforce how close they are in aggregate: the 6750 XT is 0.5% ahead of the AMD Radeon R9 M395X and 1.1% ahead of the NVIDIA GeForce RTX 3080 Ti Mobile, while the 6700M sits 0.4% behind the RTX 3080 Ti Mobile and 0.9% behind the AMD FirePro W7100.

Architecture Differences

Both GPUs are built on the same Navi 22 chip, fabricated on TSMC’s 7 nm process, with identical transistor counts of 17,200 million and a die size of 335 mm². The transistor density is 51.3M per mm² for both. They share the RDNA 2.0 architecture and support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores, and both use GDDR6 memory.

The differences begin with their roles. The RX 6750 XT is a desktop card with a dual-slot form factor, a 250 W TDP, and power connectors requiring 1x 6-pin plus 1x 8-pin, with a suggested PSU of 600 W. It measures 267 mm in length, 110 mm in height, and 40 mm in width. The RX 6700M is an integrated mobile GPU (IGP) with a 135 W TDP, no power connectors, and dimensions that are not specified. This form factor difference explains much of the performance gap, as the desktop card has far more thermal and power headroom.

Clock speeds diverge significantly. The 6750 XT runs a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. The 6700M is substantially slower on paper: 1489 MHz base, 2300 MHz game, and 2400 MHz boost. Memory clocks also differ, with the desktop part at 2250 MHz (18 Gbps effective) versus the mobile chip at 2000 MHz (16 Gbps effective).

The compute configurations are not identical either. The 6750 XT has 2560 shading units, 160 texture mapping units, 64 ROPs, and 40 ray tracing cores. The 6700M steps down to 2304 shaders, 144 TMUs, 64 ROPs, and 36 RT cores. That translates to a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s for the desktop card, versus 153.6 GPixel/s and 345.6 GTexel/s for the mobile part. FP32 throughput is 13.31 TFLOPS for the 6750 XT and 11.06 TFLOPS for the 6700M, with FP16 at 26.62 TFLOPS and 22.12 TFLOPS respectively (both at 2:1 ratio).

Memory capacity and bandwidth also favor the desktop part. The 6750 XT has 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The 6700M has 10 GB on a narrower 160-bit bus, giving it 320.0 GB/s. Both use PCIe 4.0 x16 interfaces, but the 6750 XT offers 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs, while the 6700M’s display outputs are listed as “Portable Device Dependent.”

Where Each One Wins

The RX 6750 XT is the clear choice for any workload that stresses traditional graphics pipelines, legacy DirectX APIs, or general compute outside of OpenCL. Its wins span every DirectX version tested—9, 10, 11, and 12—with margins ranging from 23.1% to 69.7%. The 52.9% lead in Passmark G3D is particularly telling for gaming scenarios, and the 38.1% advantage in 3DMark Steel Nomad DX12 indicates strong performance in modern DirectX 12 titles. The 49.3% edge in Geekbench Metal suggests Apple ecosystem compatibility is far better on the desktop card, and the 8% Vulkan lead shows it handles cross-platform graphics APIs competitively.

The 84% win in GPU compute and the 75.1% win in G2D further solidify the 6750 XT as the more versatile performer. For users running CUDA-adjacent or general-purpose compute workloads, or those who need fast 2D rendering, the desktop card is overwhelmingly superior. Its higher memory bandwidth (432.0 GB/s vs 320.0 GB/s) and larger frame buffer (12 GB vs 10 GB) also make it better suited for high-resolution textures and multi-tasking.

The RX 6700M’s sole victory in Geekbench OpenCL is its entire case. The 78.9% margin is not a narrow win—it is a dominant one. For applications that rely heavily on OpenCL compute, such as certain video encoding, scientific simulations, or proprietary software stacks, the 6700M appears to punch far above its weight. The score of 77666 versus 16360 cannot be dismissed as noise; it likely reflects driver-level optimizations that favor the mobile part’s memory subsystem or scheduling behavior in this specific API. However, this is an isolated data point, and no other benchmark in the pack corroborates it.

The average benchmark scores are nearly identical—26011 versus 25633—which means that in aggregate, the two cards are statistically comparable. The 6750 XT’s wins are broad and consistent, while the 6700M’s one win is narrow and extreme. The 71st percentile ranking for both against all GPUs places them in the same performance tier, despite the 135 W versus 250 W TDP difference.

The Verdict

From the data, the AMD Radeon RX 6750 XT is the superior GPU for almost every measured workload. It wins 10 of 11 head-to-head benchmarks, with margins that frequently exceed 50% and reach as high as 84%. Its higher clock speeds (2150 MHz base versus 1489 MHz), more shading units (2560 versus 2304), larger memory bus (192-bit versus 160-bit), and doubled bandwidth (432.0 GB/s versus 320.0 GB/s) all point to a hardware design that is simply more capable. For gamers, the 52.9% Passmark G3D lead is decisive. For professionals using Metal or Vulkan, the 49.3% and 8% advantages respectively make it the safer pick. The desktop card’s 12 GB of memory versus 10 GB also provides more headroom for future titles.

The RX 6700M should only be chosen if OpenCL compute performance is the absolute priority. Its 78.9% win in Geekbench OpenCL is the single largest delta in the entire comparison, and for users whose software stack is locked to that API, the mobile chip delivers results that the desktop card cannot match. However, this is a niche scenario. The 6700M’s lower TDP (135 W vs 250 W) makes it suitable for laptops, and its IGP form factor means it requires no separate power connectors, which is an advantage for ultra-portable systems. But in raw performance terms, the 6750 XT is ahead in every other category.

The nearest rival data confirms the 6750 XT’s positioning: it is 0.5% ahead of the R9 M395X and 1.1% ahead of the RTX 3080 Ti Mobile. The 6700M is 0.4% behind the RTX 3080 Ti Mobile and 0.9% behind the FirePro W7100. So while the two AMD cards are close in average score, the 6750 XT edges out a high-end NVIDIA mobile GPU, whereas the 6700M trails it. The desktop card’s launch MSRP was 549 USD, though pricing information is limited to that single figure.

In short, the 6750 XT is the winner for general use, gaming, and most compute workloads. The 6700M is a specialist tool for OpenCL-heavy environments, and even then, the 6750 XT’s other strengths may outweigh that single metric for most users.
