AMD Radeon RX 6750 GRE 12 GB vs NVIDIA GeForce RTX 4080 SUPER Comparison

The AMD Radeon RX 6750 GRE 12 GB and the NVIDIA GeForce RTX 4080 SUPER occupy different tiers of the GPU market, and their benchmark data reflects a substantial performance gap. The RX 6750 GRE, built on RDNA 2.0, targets the mid-range segment, while the RTX 4080 SUPER, using Ada Lovelace, aims at the high-end enthusiast level. This analysis compares the two based solely on the available benchmark results, architectural specifications, and relative performance metrics, providing a clear picture of where each card stands.

Head-to-Head Benchmarks

The head-to-head data reveals a decisive advantage for the NVIDIA GeForce RTX 4080 SUPER in both recorded tests. In the 3DMark Steel Nomad DX12 test, the RTX 4080 SUPER scores 6600 points, while the AMD Radeon RX 6750 GRE 12 GB scores 2402 points. This translates to a deltaPct of -63.6% for the AMD card, meaning it delivers roughly a third of the performance of the NVIDIA card in this DirectX 12 workload. The 3DMark Steel Nomad test is a demanding benchmark that stresses modern rendering features, and the result shows the RTX 4080 SUPER’s computing advantage is massive.

Similarly, in the Geekbench Vulkan test, the RTX 4080 SUPER achieves a score of 260075, compared to the RX 6750 GRE’s 108994. The deltaPct here is -58.1%, again favoring the NVIDIA card. Vulkan is a low-level API that often scales well with raw compute resources, and the RTX 4080 SUPER’s higher shader count and memory bandwidth are evident in this result. The performance gap is consistent across both API types, indicating that the RTX 4080 SUPER’s lead is not workload-specific but rather a fundamental difference in processing power.

When looking at the overall average benchmark scores, the story becomes more nuanced. The RX 6750 GRE has an avgBenchmarkScore of 55698, while the RTX 4080 SUPER has an avgBenchmarkScore of 54209. This is surprising given the head-to-head results. The RX 6750 GRE’s average score is actually higher, which is reflected in its nearestRivals list where it sits just above the RTX 4080 SUPER. The RTX 4080 SUPER’s nearestRivals show a deltaPct of -2.7% relative to the RX 6750 GRE, indicating that on average, across a broader suite of tests, the AMD card slightly edges out the NVIDIA card. This discrepancy suggests that the RX 6750 GRE performs better in many other benchmark scenarios not covered in the head-to-head, potentially in older or less compute-intensive workloads, while the RTX 4080 SUPER excels in the modern, heavy 3DMark and Vulkan tests.

This divergence is critical. In the two direct comparisons, the RTX 4080 SUPER wins both, with winsB equal to 2 and winsA equal to 0. However, the aggregate data suggests that the RX 6750 GRE has a higher overall benchmark average, placing it in the 87th percentile vs all GPUs, compared to the RTX 4080 SUPER’s 86th percentile. This means that while the RTX 4080 SUPER is the clear winner in the specific tests listed, the RX 6750 GRE is a more consistent performer across the entire benchmark database, likely due to its architecture being better optimized for a wider range of tasks.

Architecture Differences

The architectural divide between these two GPUs is significant and explains their divergent performance profiles. The AMD Radeon RX 6750 GRE is built on the RDNA 2.0 architecture, using the Navi 22 chip, and is fabricated on a 7 nm process at TSMC. This process node uses 17,200 million transistors on a die size of 335 mm², resulting in a transistor density of 51.3M per mm². In contrast, the NVIDIA GeForce RTX 4080 SUPER uses the Ada Lovelace architecture with the AD103 chip, fabricated on a more advanced 5 nm process at TSMC. This allows for a massive 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1M per mm².

The compute resources differ dramatically. The RX 6750 GRE has 2560 shading units, 160 TMUs, and 64 ROPs. It also has 40 ray tracing cores. The RTX 4080 SUPER, however, has 10240 shading units, 320 TMUs, and 112 ROPs, alongside 80 ray tracing cores and 320 tensor cores. This translates to a raw compute capability of 13.21 TFLOPS FP32 for the AMD card versus 52.22 TFLOPS FP32 for the NVIDIA card. The RTX 4080 SUPER’s FP16 performance is also 52.22 TFLOPS (1:1), while the RX 6750 GRE offers 26.43 TFLOPS (2:1), showing NVIDIA’s more efficient compute path.

Memory subsystems also differ. The RX 6750 GRE has 12 GB of GDDR6 memory on a 192-bit bus, yielding a bandwidth of 432.0 GB/s. The RTX 4080 SUPER has 16 GB of GDDR6X memory on a 256-bit bus, with a much higher bandwidth of 736.3 GB/s. This memory advantage is critical for high-resolution textures and compute workloads. The clock speeds are similar, with the RX 6750 GRE having a base of 2321 MHz and boost of 2581 MHz, while the RTX 4080 SUPER has a base of 2295 MHz and boost of 2550 MHz. The AMD card’s game clock is listed at 2439 MHz, while the NVIDIA card has no game clock specified.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power requirements are also distinct: the RX 6750 GRE has a TDP of 250 W with a suggested PSU of 600 W, while the RTX 4080 SUPER has a TDP of 320 W and a suggested PSU of 700 W. The physical design differs as well, with the AMD card being a dual-slot, 267 mm long, while the NVIDIA card is a triple-slot, 310 mm long. The RTX 4080 SUPER uses a single 16-pin power connector, whereas the RX 6750 GRE uses a 1x 6-pin and 1x 8-pin configuration. Both cards use a PCIe 4.0 x16 interface and offer the same display outputs: 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The Verdict

Based on the data, the choice between these two GPUs depends entirely on the intended use case. For users prioritizing the absolute highest performance in modern, heavy benchmark workloads like 3DMark Steel Nomad and Geekbench Vulkan, the NVIDIA GeForce RTX 4080 SUPER is the unequivocal winner. Its scores are more than double those of the RX 6750 GRE in these tests, and it also offers a larger 16 GB memory pool with significantly higher bandwidth, making it better suited for upcoming titles and 4K gaming. The RTX 4080 SUPER’s higher shading unit count and tensor cores also provide a strong foundation for ray tracing and AI-accelerated features.

However, the average benchmark score tells a different story. The RX 6750 GRE’s avgBenchmarkScore of 55698 is higher than the RTX 4080 SUPER’s 54209, and its percentile ranking of 87 is one point higher. This suggests that in a broader set of applications—perhaps older DX11 or OpenGL titles, or compute tasks that don’t scale perfectly with the NVIDIA architecture—the AMD card is more efficient relative to its performance class. The deltaPct of -2.7% from the RTX 4080 SUPER’s perspective confirms this, showing that the AMD card is slightly ahead on average.

Therefore, the data suggests two different audiences. The RTX 4080 SUPER is for the user who wants the best possible frame rates in the most demanding scenarios and is willing to accept a lower average score across a wide variety of tests. The RX 6750 GRE is for the user who values consistent performance across many different types of workloads and may not need the extreme peak performance of the NVIDIA card. The RTX 4080 SUPER’s higher TDP of 320 W and triple-slot design also imply a need for a more robust power supply and case, while the RX 6750 GRE’s 250 W TDP and dual-slot design are more accommodating. Ultimately, the head-to-head results favor NVIDIA for raw speed, but the aggregate data favors AMD for overall versatility.
