Where Each One Wins

Looking at the ten head-to-head tests in the database, the split is heavily in favor of the AMD Radeon RX 6750 XT. It wins seven tests, all of which are the legacy DirectX 9, DirectX 10, DirectX 11, DirectX 12, and both Passmark graphics tests. The NVIDIA GeForce RTX 3080 Mobile only manages wins in three tests: 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan.

The pattern is clear: the AMD card dominates in older API and rasterization workloads, while the NVIDIA card dominates in the newer DirectX 12 and compute-oriented API tests. The Passmark G3D and GPU compute scores also belong to AMD, with margins of 26.8% and 31.3% respectively.

The largest win for AMD in percentage terms is in Passmark DirectX 9, where the RX 6750 XT scores 263 versus 170 for the RTX 3080 Mobile, a 54.7% advantage. The single largest NVIDIA win is the 84.4% margin in Geekbench OpenCL, where the GeForce RTX 3080 Mobile hits 104,831 versus the AMD's 16,360.

Architecture Differences

The two cards sit at different points in their respective GPU families. The AMD Radeon RX 6750 XT is built on the Navi 22 chip, using the RDNA 2.0 architecture, fabricated on TSMC's 7 nm process node. The NVIDIA GeForce RTX 3080 Mobile uses the GA104 chip with the Ampere architecture, fabbed on Samsung's 8 nm node.

The NVIDIA chip includes 192 tensor cores and 48 ray tracing cores, features the AMD chip does not list. The AMD part does have a higher count of shader units, 2560 versus 6144 for NVIDIA, and its TMUs number 160 against 192. The AMD card carries 64 ROPs versus 96 for the NVIDIA chip.

Memory configurations are another clear separation. The AMD card is equipped with 12 GB of GDDR6 memory across a 192-bit bus, yielding a bandwidth of 432.0 GB/s. The NVIDIA card has 8 GB of GDDR6 on a 256-bit bus, with a bandwidth of 448.0 GB/s. The AMD has the higher capacity, while the NVIDIA has the higher bus width and bandwidth.

Clock behavior differs. The AMD Radeon RX 6750 XT has a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost up to 2600 MHz. The NVIDIA mobile RTX 3080 has a base of 1110 MHz and a boost of 1545 MHz, with no separate game clock in the pack. The memory clock is also higher on the AMD: 2250 MHz (listed as 18 Gbps effective) versus 1750 MHz (14 Gbps effective).

Head-to-Head Benchmarks

The recorded head-to-head data presents a split picture with a clear direction. In the ten tests, the AMD Radeon RX 6750 XT wins seven, all of them in DirectX 9, DirectX 10, DirectX 11, DirectX 12, and the three Passmark tests (G2D, G3D, GPU Compute). The NVIDIA GeForce RTX 3080 Mobile wins the remaining three: 3DMark Steel Nomad DX12, Geekbench OpenCL, and Geekbench Vulkan.

The most decisive AMD win is Passmark DirectX 9: 263 versus 170, a 54.7% delta. The most decisive NVIDIA win is Geekbench OpenCL: 104,831 versus 16,360, an 84.4% delta. These are not close races; each card has a domain where it is clearly dominant.

In the 3DMark Steel Nomad test, the margin narrows: the NVIDIA scores 2,644 against the AMD's 2,558, a 3.4% advantage. For Geekbench Vulkan, the NVIDIA wins 104,066 versus 98,089, only 5.7% apart.

The Passmark suite shows AMD winning by 23.3% in DirectX 11 (180 vs 146) and by 11.1% in DirectX 12 (80 vs 72). In Passmark G3D and GPU compute, AMD leads 26.8% (20,700 vs 16,321) and 31.3% (9,550 vs 7,276) respectively.

The Verdict

The data points to a simple division of labor. The AMD Radeon RX 6750 XT is the stronger card in older DirectX workloads and traditional 2D/3D rasterization tests, where it leads by margins as high as 54.7% in DirectX 9 and 52.6% in the G2D test. It also offers more memory (12 GB vs 8 GB), more TMUs and ROPs, and a higher base and boost clock, while drawing more board power (250 W TDP vs 115 W) and requiring external power connectors.

The NVIDIA GeForce RTX 3080 Mobile, by contrast, is the pick in compute-heavy modern workloads: Geekbench OpenCL and Vulkan, and 3DMark Steel Nomad. Its Ampere architecture includes 192 tensor cores and 40 RT cores, which the Radeon does not have, and it delivers significantly higher FP32 throughput (18.98 TFLOPS versus 13.31 TFLOPS). It also does all of that inside a lower 115 W power envelope, with no external power connector, and a higher memory bandwidth of 448.0 GB/s.

The choice comes down to workload. For legacy DirectX titles and general 2D/3D rasterization, the AMD Radeon RX 6750 XT has the clear edge, often by double-digit percentage margins. For DX12 Ultimate, Vulkan, and compute applications, the NVIDIA GeForce RTX 3080 Mobile is the stronger pick, with the largest single margin being its 84.4% lead in Geekbench OpenCL. The data does not support one universal winner; it supports two specialized ones.
