AMD Radeon RX 6750 XT vs NVIDIA GeForce RTX 2080 Ti Comparison

Head-to-Head Benchmarks

The recorded data shows a clear, though not universal, advantage for the NVIDIA GeForce RTX 2080 Ti in the head-to-head benchmark suite. Out of ten paired tests, the RTX 2080 Ti claims eight wins, while the AMD Radeon RX 6750 XT takes two. The most dramatic margin appears in the Geekbench OpenCL test, where the RTX 2080 Ti scores 128,171 against the RX 6750 XT’s 16,360, a massive 683.4% difference. This is the single largest gap in the entire comparison, and it is far outside the pattern seen in other tests. It suggests a workload-specific advantage for the NVIDIA architecture in that particular compute benchmark, rather than a general performance trend.

Outside of that outlier, the RTX 2080 Ti’s wins are mostly moderate. In 3DMark Steel Nomad DX12, the NVIDIA card scores 3,537 versus 2,548 for AMD, a 38.8% lead. The Geekbench Vulkan result also favors NVIDIA, with 132,930 points against 98,089, a 35.5% advantage. These are substantial and consistent with the expectations for a higher-tier card in modern API workloads. In the Passmark suite, the RTX 2080 Ti leads in DirectX 10 (153 vs 125, a 22.4% margin), DirectX 11 (190 vs 180, a 5.6% margin), and DirectX 12 (84 vs 80, a 5% margin). Its Passmark G3D score of 21,548 edges out AMD’s 20,700 by 4.1%, and the GPU compute test shows 10,056 versus 9,550, a 5.3% advantage.

The RX 6750 XT’s two wins are narrower. In Passmark DirectX 9, AMD scores 263 against NVIDIA’s 235, a 10.6% advantage. In the Passmark G2D test, AMD leads 972 to 927, a 4.6% margin. These are older or 2D-oriented workloads, and the AMD card’s wins there do not offset the breadth of NVIDIA’s leads in modern APIs and compute tasks. The average benchmark score reinforces this: the RTX 2080 Ti sits at 29,783, while the RX 6750 XT averages 26,011. The delta between the two is roughly 14.5% in favor of NVIDIA, which aligns with the overall win count. The RTX 2080 Ti also ranks at the 75th percentile among all GPUs, while the RX 6750 XT sits at the 71st percentile, a small but real separation in the database’s overall distribution.

Architecture Differences

The architectural divide between these two cards is significant, reflecting different design philosophies and process technologies. The RTX 2080 Ti uses the TU102 chip, built on Turing architecture, fabricated by TSMC on a 12 nm process. The die is large at 754 mm², and it packs 18,600 million transistors, giving a transistor density of 24.7 million per square millimeter. The RX 6750 XT, in contrast, uses the Navi 22 chip, built on RDNA 2.0 architecture, also fabricated by TSMC but on a 7 nm process. Its die is much smaller at 335 mm², yet it holds 17,200 million transistors, resulting in a density of 51.3 million per square millimeter. That density difference is a direct outcome of the newer node: AMD fits nearly as many transistors in less than half the silicon area.

The compute resources differ in configuration. The RTX 2080 Ti has 4,352 shading units, 272 texture mapping units, and 88 raster output units. It also includes 68 ray tracing cores and 544 tensor cores, the latter being a Turing hallmark for AI workloads. The RX 6750 XT has 2,560 shading units, 160 TMUs, and 64 ROPs, with 40 ray tracing cores and no tensor cores at all. Despite having fewer units, the AMD card achieves comparable raw throughput: its FP32 peak is 13.31 TFLOPS versus 13.45 TFLOPS for NVIDIA, and FP16 is 26.62 TFLOPS versus 26.90 TFLOPS. The pixel rate tells a different story, with AMD at 166.4 GPixel/s versus NVIDIA’s 136.0 GPixel/s, and texture rates are nearly identical at 416.0 GTexel/s for AMD and 420.2 GTexel/s for NVIDIA. The RTX 2080 Ti’s higher unit count is offset by its lower clock speeds (base 1350 MHz, boost 1545 MHz) compared to the RX 6750 XT (base 2150 MHz, boost 2600 MHz, game clock 2495 MHz).

Memory subsystems also diverge. The RTX 2080 Ti uses 11 GB of GDDR6 on a 352-bit bus, delivering 616.0 GB/s of bandwidth. The RX 6750 XT has 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s of bandwidth. The NVIDIA card’s wider bus gives it a 42.6% bandwidth advantage, which likely contributes to its performance in memory-heavy compute tasks. The AMD card has more capacity, but the narrower bus limits its throughput. The PCIe interface also differs: the RTX 2080 Ti uses PCIe 3.0 x16, while the RX 6750 XT uses PCIe 4.0 x16, giving AMD a newer interconnect standard.

The Verdict

Based strictly on the recorded data, the NVIDIA GeForce RTX 2080 Ti is the stronger performer in the majority of tested workloads. It wins eight of ten head-to-head benchmarks, including all modern API tests (DX12, Vulkan, and Steel Nomad) and the dominant OpenCL compute result. Its average benchmark score of 29,783 is higher than the RX 6750 XT’s 26,011, and its 75th percentile ranking versus AMD’s 71st percentile confirms the overall lead. The RX 6750 XT does win in DirectX 9 and G2D, but those are legacy or 2D workloads with limited relevance to modern gaming or compute tasks.

For a user prioritizing raw performance in DX12, Vulkan, or compute-heavy applications, the RTX 2080 Ti is the clear choice from this data. Its 38.8% lead in 3DMark Steel Nomad and 35.5% lead in Vulkan are decisive. The RX 6750 XT, however, offers a newer process node, more memory capacity (12 GB versus 11 GB), and a higher pixel rate. It also has a much lower launch MSRP of 549 USD, compared to the RTX 2080 Ti’s 999 USD, though this analysis does not weigh cost as a factor. The data alone points to NVIDIA for performance, with AMD’s card being a respectable but secondary option.

Where Each One Wins

The NVIDIA GeForce RTX 2080 Ti dominates in every modern 3D and compute workload recorded. Its 38.8% lead in 3DMark Steel Nomad DX12 is the standout win for contemporary gaming APIs. The Vulkan test shows a 35.5% advantage, and the OpenCL test shows a staggering 683.4% lead, indicating a strong position for compute tasks such as rendering, simulation, or machine learning inference. In the Passmark suite, NVIDIA wins DirectX 10, DirectX 11, DirectX 12, G3D, and GPU compute, with margins ranging from 4.1% to 22.4%. This makes the RTX 2080 Ti the pick for users targeting DX12-era games, Vulkan titles, or any workload that leverages compute shaders.

The AMD Radeon RX 6750 XT wins in two specific areas. Its DirectX 9 score of 263 versus 235 (a 10.6% lead) makes it better suited for legacy DirectX 9 titles, which some older games still rely upon. Its G2D win (972 vs 927, a 4.6% margin) suggests slightly better 2D performance, which could matter for desktop compositing or certain productivity applications. Neither of these wins affects modern gaming performance, but they do give AMD a niche advantage in backward compatibility and 2D rendering.

Specification Differences

The two cards differ across nearly every core specification. The RTX 2080 Ti uses a 12 nm process with a 754 mm² die, while the RX 6750 XT uses a 7 nm process with a 335 mm² die. Transistor counts are close, at 18,600 million for NVIDIA and 17,200 million for AMD, but density is far higher on the newer node (51.3M / mm² versus 24.7M / mm²). The RTX 2080 Ti has more shading units (4,352 vs 2,560), more TMUs (272 vs 160), and more ROPs (88 vs 64). It also has 68 ray tracing cores and 544 tensor cores, while the RX 6750 XT has 40 ray tracing cores and no tensor cores.

Clock speeds are higher on the AMD card: base 2150 MHz, boost 2600 MHz, with a game clock of 2495 MHz, versus NVIDIA’s base 1350 MHz and boost 1545 MHz. Memory differences are significant: the RTX 2080 Ti has 11 GB with a 352-bit bus and 616.0 GB/s bandwidth, while the RX 6750 XT has 12 GB with a 192-bit bus and 432.0 GB/s bandwidth. The pixel rate favors AMD (166.4 GPixel/s vs 136.0 GPixel/s), while texture rates are nearly equal (416.0 vs 420.2 GTexel/s). FP32 and FP16 performance are also close, with NVIDIA at 13.45/26.90 TFLOPS and AMD at 13.31/26.62 TFLOPS. The RTX 2080 Ti uses PCIe 3.0 x16 and two 8-pin power connectors, while the RX 6750 XT uses PCIe 4.0 x16 and one 6-pin plus one 8-pin connector. Both are dual-slot cards with a 250 W TDP and a suggested 600 W PSU, but the RTX 2080 Ti adds a USB Type-C output alongside HDMI and DisplayPort, whereas the RX 6750 XT offers only HDMI and DisplayPort.
