AMD Radeon RX 6750 XT vs NVIDIA GeForce RTX 2080 Comparison

Head-to-Head Benchmarks

The benchmark database records a clear split between these two cards, with AMD taking 7 of the 10 head-to-head tests and NVIDIA winning 3. The largest margin belongs to AMD in the 3DMark Steel Nomad DX12 test, where the Radeon RX 6750 XT scores 2548 against the RTX 2080's 1752, a 45.4% advantage. That is the single most decisive result in the comparison, and it points to a substantial gap in modern DirectX 12 rasterization workloads.

NVIDIA's most emphatic response comes in Geekbench OpenCL, where the RTX 2080 posts 91313 versus 16360 for the Radeon. That is an 82.1% deficit for AMD, the largest delta in either direction across the entire benchmark suite. The OpenCL result is striking because it reverses the overall trend, suggesting that the RTX 2080's compute-oriented architecture handles certain general-purpose GPU workloads far more efficiently.

The remaining NVIDIA win is in Geekbench Vulkan, where the RTX 2080 scores 107797 against 98089 for the RX 6750 XT, a 9% difference. This is a modest win, but it is notable because Vulkan is a low-level API that tends to favor architectural efficiency over raw specifications. The RTX 2080 also edges out the Radeon in Passmark DirectX 10, scoring 136 versus 125, an 8.1% margin.

AMD's wins in the Passmark suite are consistent and meaningful. In DirectX 11, the RX 6750 XT scores 180 versus 158, a 13.9% lead. In DirectX 12, the margin is 11.1% with scores of 80 and 72. The DirectX 9 test shows a 17.9% advantage for AMD, with 263 against 223. The Passmark G3D score, which is a broader gaming-oriented metric, favors AMD by 10.6% at 20700 versus 18720. The G2D (2D graphics) test also goes to AMD at 972 versus 907, a 7.2% edge.

The GPU compute benchmark from Passmark is another strong AMD result: 9550 versus 7872, a 21.3% lead. This is important because it shows that AMD's advantage is not limited to gaming graphics; it extends into compute tasks as well, at least as measured by this particular test.

Across the full suite, the average benchmark score for the RX 6750 XT is 26011, placing it in the 71st percentile of all GPUs in the database. The RTX 2080 averages 22895, sitting in the 68th percentile. The raw score gap is 3116 points, which translates to a roughly 13.6% overall advantage for the Radeon based on the recorded averages.

Where Each One Wins

The data paints a clear picture for gaming workloads. The RX 6750 XT wins the DirectX 9, 11, and 12 Passmark tests, plus the G3D gaming metric and the 3DMark Steel Nomad DX12 test. If the workload is traditional rasterized gaming, the AMD card holds the advantage in every recorded test except DirectX 10, where NVIDIA leads by a small 8.1% margin.

For compute-heavy tasks, the picture is more nuanced. The RTX 2080 dominates the Geekbench OpenCL test with an 82.1% lead, which is a massive margin. This suggests that OpenCL-based workloads, such as certain scientific simulations, video encoding, or machine learning inference tasks that use OpenCL, would perform substantially better on the NVIDIA card. The Vulkan result also favors NVIDIA, though by a much smaller 9% margin.

AMD wins the Passmark GPU compute test by 21.3%, which partially offsets the OpenCL result. The discrepancy between these two compute benchmarks is worth noting: the Passmark compute test likely uses a different set of operations than Geekbench OpenCL, and the results indicate that neither card is universally faster at compute tasks.

In terms of overall standing, the RX 6750 XT's nearest rivals in the database are the AMD Radeon R9 M395X (0.5% behind), the AMD FirePro W7100 (0.6% behind), and the AMD FirePro D700 (0.7% behind). The RTX 2080's nearest rivals include the Intel Arc B580 (0.5% ahead), the AMD Radeon RX 580 2048SP (0.7% ahead), and the NVIDIA GeForce RTX 4060 Mobile (0.7% behind). Neither card is isolated in the rankings; both sit within roughly 1% of several comparable products.

Architecture Differences

The two GPUs come from fundamentally different architectural generations. The RX 6750 XT uses the Navi 22 chip built on RDNA 2.0 architecture, produced on a 7 nm process at TSMC. The RTX 2080 uses the TU104 chip with Turing architecture, fabricated on a 12 nm process, also at TSMC. The process node difference is significant: 7 nm versus 12 nm allows AMD to pack more transistors into a smaller area. The Navi 22 die measures 335 mm² and contains 17,200 million transistors, giving a density of 51.3 million transistors per square millimeter. The TU104 die is larger at 545 mm² but contains fewer transistors at 13,600 million, resulting in a density of just 25.0 million per square millimeter.

Memory configurations differ substantially. The RX 6750 XT carries 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The RTX 2080 has 8 GB of GDDR6 on a wider 256-bit bus, achieving 448.0 GB/s. Despite the narrower bus, AMD's higher effective memory clock (18 Gbps versus 14 Gbps) keeps bandwidth competitive, with only a 3.6% difference in favor of NVIDIA.

Shader and compute resources are distributed differently. The RX 6750 XT has 2560 shading units, 160 texture mapping units, and 64 ROPs, along with 40 ray tracing cores. The RTX 2080 has 2944 shading units, 184 TMUs, and 64 ROPs, plus 46 RT cores and 368 tensor cores. The higher raw shader count and TMU count on the NVIDIA card do not translate into higher performance in most recorded tests, which speaks to the efficiency of AMD's RDNA 2 design.

Clock speeds are a major differentiator. The RX 6750 XT runs at a base clock of 2150 MHz and boosts to 2600 MHz, with a game clock of 2495 MHz. The RTX 2080 has a base clock of 1515 MHz and a boost of 1710 MHz. This is a 41.9% higher base clock and a 52% higher boost clock for the AMD card. The RDNA 2 architecture achieves these higher clocks while maintaining a 250 W TDP, compared to 215 W for the RTX 2080.

The compute throughput reflects these clock advantages. The RX 6750 XT delivers 13.31 TFLOPS FP32 and 26.62 TFLOPS FP16 (2:1), while the RTX 2080 produces 10.07 TFLOPS FP32 and 20.14 TFLOPS FP16. The pixel rate is 166.4 GPixel/s for AMD versus 109.4 GPixel/s for NVIDIA, and the texture rate is 416.0 GTexel/s versus 314.6 GTexel/s. These are substantial leads for AMD in every throughput metric.

Interface and connectivity also differ. The RX 6750 XT uses PCIe 4.0 x16, while the RTX 2080 is limited to PCIe 3.0 x16. Display outputs are similar in count, but AMD offers HDMI 2.1 versus HDMI 2.0 on NVIDIA, and NVIDIA adds a USB Type-C port. Both cards use the same power connector configuration (1x 6-pin + 1x 8-pin), but AMD recommends a 600 W power supply versus 550 W for NVIDIA.

The Verdict

The recorded data favors the AMD Radeon RX 6750 XT for most users. It wins 7 of 10 benchmark comparisons, including the most demanding modern DirectX 12 test by 45.4%. Its average benchmark score is 3116 points higher, and it sits in a higher percentile ranking. For gaming, the evidence is clear: the RX 6750 XT delivers better performance across DirectX 9, 11, 12, and the G3D metric, with margins ranging from 10.6% to 17.9%.

The RTX 2080 retains a specific niche. Its 82.1% lead in Geekbench OpenCL makes it the obvious choice for workflows that rely heavily on OpenCL compute. The 9% Vulkan advantage is also worth noting, though it is less decisive. Users who prioritize these specific workloads over gaming performance should consider the RTX 2080.

The architecture comparison supports AMD's position. The RX 6750 XT achieves higher clock speeds, higher pixel and texture rates, and higher FP32 and FP16 throughput, all while using a smaller die and a more advanced process node. The RTX 2080 counters with more shading units, more TMUs, more RT cores, and the addition of tensor cores, but these specifications do not translate into benchmark wins outside of OpenCL and Vulkan.

Memory capacity is another point for AMD: 12 GB versus 8 GB is a 50% advantage, which matters for modern games and larger textures. The bandwidth difference is minor, with NVIDIA leading by only 16 GB/s.

For the majority of users, especially those focused on gaming, the RX 6750 XT is the stronger card based on the recorded measurements. For OpenCL-heavy compute tasks, the RTX 2080 is the clear winner. The choice comes down to workload: general gaming and most compute favors AMD, while OpenCL-specific applications favor NVIDIA.
