AMD Radeon RX 6750 GRE 12 GB vs NVIDIA GeForce RTX 5090 D Comparison

Head-to-Head Benchmarks

The benchmark database pits the NVIDIA GeForce RTX 5090 D against the AMD Radeon RX 6750 GRE 12 GB in two recorded DirectX and Vulkan workloads. The results are not close. In 3DMark Steel Nomad DX12, the RTX 5090 D scores 14,326 points against 2,402 points for the RX 6750 GRE, a delta of 496.4%. That means the NVIDIA card delivers nearly five times the raw rasterization throughput in this specific stress test. The RX 6750 GRE is not merely slower; it is in a completely different performance tier.

The second recorded benchmark, Geekbench Vulkan, shows a similar gap. The RTX 5090 D posts 376,915 points, while the RX 6750 GRE manages 108,994 points, a delta of 245.8%. In compute-oriented Vulkan workloads, the NVIDIA card is roughly two and a half times faster. Both wins belong to NVIDIA, with a clean 2-0 sweep in the head-to-head table. The RX 6750 GRE has no recorded victory in any shared benchmark.

Context from the broader database makes these numbers more striking. The RTX 5090 D sits at the 92nd percentile among all GPUs, with an average benchmark score of 77,712. Its nearest rivals include the AMD Radeon RX 6850M XT at 78,940 (1.6% behind the RTX 5090 D) and the NVIDIA Tesla P100 PCIe 16 GB at 79,605 (2.4% behind). The RTX 5090 D is effectively at the top of the heap, trading places only with other flagship-class accelerators. The RX 6750 GRE, by contrast, holds the 87th percentile with an average score of 55,698. Its nearest rivals are the AMD Radeon 8060S at 55,757 (0.1% ahead), the NVIDIA GeForce RTX 5080 at 56,083 (0.7% ahead), the AMD Radeon Pro W5700X at 54,828 (1.6% behind), and the NVIDIA GeForce RTX 4080 at 54,247 (2.7% behind). The RX 6750 GRE is a solid mid-range part, but it is nowhere near the RTX 5090 D in absolute performance.

The delta between the two cards in 3DMark Steel Nomad is so large that it dwarfs any other comparison in the database. A 496.4% advantage means the RTX 5090 D completes the workload in roughly one-sixth of the time, assuming linear scaling. In Geekbench Vulkan, the 245.8% lead translates to the NVIDIA card finishing the compute tasks with more than double the throughput. For any application that scales with raw GPU compute, the RTX 5090 D is the clear choice.

The Verdict

The data presents a straightforward conclusion: the NVIDIA GeForce RTX 5090 D is the superior performer in every shared benchmark. Anyone who needs maximum frame rates, high-resolution rendering, or heavy compute workloads should choose the RTX 5090 D without hesitation. The 3DMark Steel Nomad score of 14,326 versus 2,402 is a decisive, generation-defining gap. The Geekbench Vulkan result of 376,915 versus 108,994 reinforces that this is not a single-workload fluke; the NVIDIA card wins across both DirectX and Vulkan paths.

The AMD Radeon RX 6750 GRE 12 GB is a different kind of product. Its 87th percentile ranking and average score of 55,698 place it in the upper-middle tier, competing with the RTX 5080 and RTX 4080 in the database's scoring system. It is not a weak card, but it is not in the same league as the RTX 5090 D. For users who prioritize the specific workloads measured here, the RX 6750 GRE will leave them wanting more.

Who should pick the RX 6750 GRE? Based strictly on the recorded data, only a user who does not need the performance headroom of the RTX 5090 D. The RX 6750 GRE has lower raw scores, but it also has a lower launch MSRP of 334 USD, which the database records once here. That price difference is substantial, but the benchmark data shows that the performance gap is even more substantial. There is no scenario in these two tests where the RX 6750 GRE wins. For professional users, content creators, or enthusiasts running 3DMark Steel Nomad or Vulkan compute, the RTX 5090 D is the only rational pick. For casual gamers on modest resolutions, the RX 6750 GRE will suffice, but the data does not support any claim of parity.

Specification Differences

The two cards differ across nearly every major specification. The RTX 5090 D is built on the GB202 chip with the Blackwell 2.0 architecture, while the RX 6750 GRE uses the Navi 22 chip with RDNA 2.0. The manufacturing process also differs: the RTX 5090 D uses a 5 nm node at TSMC, and the RX 6750 GRE uses a 7 nm node at TSMC. Transistor counts are dramatically different, with the RTX 5090 D containing 92,200 million transistors on a 750 mm² die, versus 17,200 million transistors on a 335 mm² die for the RX 6750 GRE. Transistor density is 122.9M per mm² for the NVIDIA card and 51.3M per mm² for the AMD card.

Clock speeds tell a nuanced story. The RX 6750 GRE has a higher base clock of 2321 MHz and a higher boost clock of 2581 MHz, with a game clock of 2439 MHz. The RTX 5090 D has a lower base clock of 2017 MHz and a boost clock of 2407 MHz. Memory clocks are also different, with the RTX 5090 D running at 1750 MHz (28 Gbps effective) and the RX 6750 GRE at 2250 MHz (18 Gbps effective). The memory configuration is a major divider: 32 GB of GDDR7 on a 512-bit bus for NVIDIA, versus 12 GB of GDDR6 on a 192-bit bus for AMD.

Compute resources are vastly different. The RTX 5090 D has 21,760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The RX 6750 GRE has 2,560 shading units, 160 TMUs, 64 ROPs, 40 RT cores, and no tensor cores. The pixel rate is 423.6 GPixel/s for the RTX 5090 D versus 165.2 GPixel/s for the RX 6750 GRE. Texture rate is 1,636.8 GTexel/s versus 413.0 GTexel/s. FP32 performance is 104.8 TFLOPS for the NVIDIA card and 13.21 TFLOPS for the AMD card. FP16 performance is 104.8 TFLOPS (1:1) for the RTX 5090 D and 26.43 TFLOPS (2:1) for the RX 6750 GRE.

Power and physical characteristics also differ. The RTX 5090 D has a TDP of 575 W with a suggested PSU of 950 W and a single 16-pin connector. The RX 6750 GRE has a TDP of 250 W with a suggested PSU of 600 W and a 6-pin plus 8-pin connector configuration. Both are dual-slot cards, but the RTX 5090 D is longer at 304 mm versus 267 mm for the RX 6750 GRE. The bus interface is PCIe 5.0 x16 for the NVIDIA card and PCIe 4.0 x16 for the AMD card. Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b for the RTX 5090 D, and 1x HDMI 2.1 and 3x DisplayPort 1.4a for the RX 6750 GRE. The release dates are 2025-01-29 for the RTX 5090 D and 2023-10-16 for the RX 6750 GRE.

Architecture Differences

The architectural divide is fundamental. The RTX 5090 D uses the Blackwell 2.0 architecture, which is NVIDIA's latest generation, and it is built on a 5 nm process at TSMC. The RX 6750 GRE uses RDNA 2.0, which is AMD's previous-generation architecture, on a 7 nm process. The process node difference alone explains part of the transistor density gap: 122.9M transistors per mm² for the RTX 5090 D versus 51.3M per mm² for the RX 6750 GRE. The RTX 5090 D packs 92,200 million transistors, while the RX 6750 GRE has 17,200 million.

The RTX 5090 D supports dedicated tensor cores, with 680 of them, which the RX 6750 GRE completely lacks. This means the NVIDIA card can accelerate AI workloads and deep learning inference directly in hardware, while the AMD card relies on general-purpose shader compute. The RT core counts also differ significantly: 170 for the RTX 5090 D versus 40 for the RX 6750 GRE. Ray tracing workloads will scale accordingly, with the RTX 5090 D having more than four times the dedicated RT hardware.

Memory architecture is another major divergence. The RTX 5090 D uses GDDR7 memory, the newest standard, with 32 GB on a 512-bit bus, achieving 1.79 TB/s of bandwidth. The RX 6750 GRE uses GDDR6, with 12 GB on a 192-bit bus, achieving 432.0 GB/s. The bandwidth difference is roughly 4.1 times in favor of the RTX 5090 D. The FP16 ratio also differs, with the RTX 5090 D offering 1:1 FP16 to FP32 throughput, while the RX 6750 GRE offers 2:1 FP16 to FP32, meaning the AMD card's FP16 output is double its FP32 output, but its absolute FP16 is still lower.

The API support is identical for both cards: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software compatibility is not a differentiator. The generation gap is clear: the RTX 5090 D succeeds the GeForce 40 series and is followed by the GeForce 60 series, while the RX 6750 GRE sits in the Navi II generation, succeeding Navi and preceding Navi III. The production status for both is active, so both remain available in the market. The architectural differences, combined with the massive transistor and memory advantages, fully explain the benchmark results.
