AMD Radeon RX 6750 XT vs NVIDIA GeForce RTX 5070 Mobile Comparison

NVIDIA GeForce RTX 5070 Mobile and AMD Radeon RX 6750 XT represent two very different approaches to graphics hardware: one is a 50 W integrated-class mobile part built on a state-of-the-art 5 nm process, the other is a 250 W, dual-slot desktop card on 7 nm. The benchmark data shows a clear split in strengths, with the RTX 5070 Mobile dominating compute and modern API workloads while the RX 6750 XT leads in legacy DirectX 9 and 2D tasks. Their average benchmark scores sit at 29928 for the NVIDIA part and 26011 for the AMD part, but the recorded wins are split nearly evenly at 5 versus 4.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Mobile is the clear winner in raw compute and modern graphics API workloads. Its Geekbench OpenCL score of 122238 absolutely demolishes the RX 6750 XT's 16360, a staggering 647.2% advantage. This is not a marginal lead; it indicates that the RTX 5070 Mobile's architecture is far more efficient at general-purpose compute tasks. In Vulkan, the GeForce part again takes the win with 116960 versus 98089, a 19.2% margin. The DirectX 11 and DirectX 12 results also favor NVIDIA, with the RTX 5070 Mobile leading by 6.7% (192 versus 180) and 16.3% (93 versus 80) respectively, showing a consistent advantage in the APIs that power most current PC games.

The AMD Radeon RX 6750 XT carves out its victories in older and more specialized workloads. Its DirectX 9 score of 263 beats the RTX 5070 Mobile's 214 by 18.6%. For 2D performance, the Passmark G2D score of 972 versus 896 gives AMD a 7.8% lead. The RX 6750 XT also wins the Passmark G3D test with 20700 against 20355, a modest but real 1.7% advantage. In GPU compute, the AMD card takes a more substantial win with 9550 versus 8279, a 13.3% margin. This suggests that in specific compute tasks that are not covered by the Geekbench OpenCL test, the RX 6750 XT has genuine strengths.

The split is essentially about workload age and type. The RTX 5070 Mobile is optimized for the latest DirectX 12 and Vulkan titles and for compute-heavy applications, while the RX 6750 XT holds its ground in legacy DX9 scenarios and in certain 2D and compute workloads where its higher clock speeds and larger ROP count help.

Architecture Differences

The two GPUs are built on fundamentally different architectures and processes. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip based on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The die is compact at 181 mm² and houses 21,900 million transistors, giving a transistor density of 121.0M per mm². The AMD Radeon RX 6750 XT uses the Navi 22 chip with RDNA 2.0 architecture, built on a 7 nm process, also at TSMC. Its die is much larger at 335 mm² but contains fewer transistors at 17,200 million, resulting in a lower density of 51.3M per mm².

Memory configurations differ significantly. The RTX 5070 Mobile has 8 GB of GDDR7 memory on a 128 bit bus, delivering 384.0 GB/s of bandwidth. The RX 6750 XT has 12 GB of GDDR6 memory on a wider 192 bit bus, providing 432.0 GB/s of bandwidth. The AMD card has a clear capacity and bandwidth advantage, though the GDDR7 type on the NVIDIA part is newer. Clock speeds also diverge: the RTX 5070 Mobile has a base clock of 907 MHz and a boost of 1425 MHz, while the RX 6750 XT runs at 2150 MHz base and 2600 MHz boost. The AMD card is clocked much higher, which contributes to its wins in certain tests.

The compute pipelines are structured differently. The RTX 5070 Mobile has 4608 shading units, 144 TMUs, and 48 ROPs, with 36 RT cores and 144 tensor cores. The RX 6750 XT has 2560 shading units, 160 TMUs, and 64 ROPs, with 40 RT cores and no tensor cores. Despite fewer shading units, the AMD card achieves higher pixel rate (166.4 GPixel/s versus 68.40 GPixel/s) and texture rate (416.0 GTexel/s versus 205.2 GTexel/s) due to its higher clocks. FP32 performance is nearly identical at 13.31 TFLOPS for AMD and 13.13 TFLOPS for NVIDIA.

Power and physical characteristics are opposites. The RTX 5070 Mobile is a 50 W IGP with no power connectors and uses PCIe 5.0 x16. The RX 6750 XT is a 250 W dual-slot card with 1x 6-pin and 1x 8-pin power connectors, requiring a 600 W PSU, and uses PCIe 4.0 x16. The AMD card has physical dimensions of 267 mm length, 110 mm height, and 40 mm width. The NVIDIA part has no listed dimensions. The RX 6750 XT shows 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs, while the RTX 5070 Mobile's outputs are described as portable device dependent.

Head-to-Head Benchmarks

The largest single victory in the head-to-head data belongs to the RTX 5070 Mobile in Geekbench OpenCL. Its score of 122238 versus 16360 represents a 647.2% lead, an outlier that drives much of the NVIDIA card's average score advantage. This result alone separates the two GPUs by an enormous margin in compute-heavy tasks. The other NVIDIA wins are more modest but consistent: 19.2% in Vulkan, 16.3% in DirectX 12, 6.7% in DirectX 11, and 3.2% in DirectX 10.

The AMD Radeon RX 6750 XT's biggest win is in DirectX 9, where it beats the RTX 5070 Mobile by 18.6%. This is followed by a 13.3% win in Passmark GPU Compute, a 7.8% win in G2D, and a narrow 1.7% win in G3D. The G3D result is particularly close, with 20700 versus 20355, showing that in this aggregate gaming test, the two are nearly equivalent. The compute comparison is interesting: the AMD card wins Passmark GPU Compute by 13.3%, but loses Geekbench OpenCL by 647.2%, indicating that these two tests measure very different aspects of compute performance.

The average benchmark scores place the RTX 5070 Mobile at 29928, which is 15.0% above the RX 6750 XT's 26011. The percentile rankings reflect this: the RTX 5070 Mobile sits at the 75th percentile of all GPUs, while the RX 6750 XT is at the 71st percentile. The nearest rivals for the RTX 5070 Mobile include the NVIDIA GeForce RTX 3070 Ti (29945, 0.1% higher), the AMD Radeon RX 6800 (30095, 0.6% higher), and the AMD Radeon RX 6700 (30433, 1.7% higher). The RX 6750 XT's nearest rivals are all older or lower-tier parts, including the AMD FirePro D700 (25842, 0.7% lower) and the NVIDIA GeForce RTX 3080 Ti Mobile (25740, 1.1% lower).

The Verdict

The data supports a clear division of use cases. For users running modern DirectX 12 and Vulkan games, or applications that leverage OpenCL compute, the NVIDIA GeForce RTX 5070 Mobile is the superior choice. Its 19.2% lead in Vulkan and 16.3% lead in DirectX 12 are decisive, and the massive OpenCL advantage makes it the obvious pick for compute workloads. The 75th percentile ranking and average score of 29928 place it above 71st-percentile RX 6750 XT.

The AMD Radeon RX 6750 XT is the better option for legacy DirectX 9 titles, where it leads by 18.6%, and for 2D workloads where its 7.8% G2D advantage matters. It also has 12 GB of memory versus 8 GB, which may be relevant for capacity-sensitive tasks, and its higher boost clock of 2600 MHz versus 1425 MHz explains its wins in clock-speed-driven tests. However, its 250 W power draw and dual-slot form factor are significant drawbacks compared to the 50 W IGP of the RTX 5070 Mobile.

Overall, the RTX 5070 Mobile is the stronger product in the database's measurements. It wins the head-to-head 5 to 4, has a higher average score, and holds a higher percentile ranking. The RX 6750 XT's wins are in older or more niche workloads, while the RTX 5070 Mobile wins in the APIs that matter most for current and future gaming. The RTX 5070 Mobile also matches the RX 6750 XT in FP32 compute (13.13 TFLOPS versus 13.31 TFLOPS) while using a fraction of the power. For anyone building a portable device, the RTX 5070 Mobile is the clear choice. For desktop users with a 600 W PSU who prioritize DX9 and 2D performance, the RX 6750 XT remains relevant, but it is an end-of-life product against an active one.
