AMD Radeon RX 7900 GRE vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the AMD Radeon RX 7900 GRE and the NVIDIA GeForce RTX 5080 SUPER: the 3DMark Steel Nomad DX12 test. The AMD Radeon RX 7900 GRE delivers a score of 4814, while the NVIDIA GeForce RTX 5080 SUPER scores 3075. This represents a decisive 56.6% advantage for the AMD card in this specific workload, making it the clear winner in the only head-to-head benchmark available.

The magnitude of this delta is substantial. A 56.6% lead in a modern DX12 test indicates that the AMD Radeon RX 7900 GRE is far more efficient at executing this particular rendering workload. The NVIDIA GeForce RTX 5080 SUPER, despite its newer architecture and higher specifications in some areas, trails significantly in this measurement. The data shows that the AMD card's score of 4814 places it well ahead, and the NVIDIA card would need a considerable performance uplift to match it in this test.

When placed in the broader context of the database, the AMD Radeon RX 7900 GRE holds a 77th percentile ranking among all GPUs, with an average benchmark score of 32456 across all recorded tests. Its nearest rivals in the database include the AMD FirePro S10000 with an average score of 32388 and a delta of 0.2%, and the AMD Radeon Pro 570X with an average score of 32176 and a delta of 0.9%. The NVIDIA GeForce RTX 5080 SUPER, however, has a 19th percentile ranking and an average benchmark score of only 3075, which is derived solely from that single Steel Nomad run. Its nearest rivals include the NVIDIA Quadro P1000 with an average score of 3163 and a delta of -2.8%, and the Intel Arc Pro B60 with an average score of 3182 and a delta of -3.4%.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The AMD Radeon RX 7900 GRE uses the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito, and belongs to the Navi III generation within the Radeon RX 7000 series. The NVIDIA GeForce RTX 5080 SUPER uses the Blackwell 2.0 architecture with the GB203 chip and belongs to the GeForce 50 generation within the GeForce 50-series. Both are manufactured by TSMC on a 5 nm process node, but the design philosophies diverge significantly.

The AMD card integrates 80 ray tracing cores and no tensor cores, while the NVIDIA card integrates 84 ray tracing cores and 336 tensor cores. This makes the NVIDIA card specifically equipped for tensor-based workloads, a feature entirely absent from the AMD card's specification list. The AMD card also relies on a 2:1 FP16 ratio, meaning it can perform twice the FP16 operations as FP32, whereas the NVIDIA card performs FP16 at a 1:1 ratio with FP32.

The memory subsystems also reflect architectural choices. The AMD Radeon RX 7900 GRE pairs 16 GB of GDDR6 memory with a 256-bit bus, achieving 576.0 GB/s bandwidth. The NVIDIA GeForce RTX 5080 SUPER uses 24 GB of GDDR7 memory on a 256-bit bus, achieving 1.02 TB/s bandwidth. The GDDR7 memory type is a newer generation, and the higher capacity of 24 GB alongside the doubled bandwidth indicates a focus on memory-intensive tasks.

The physical dimensions and power delivery also differ. The AMD card is 276 mm long, 110 mm tall, and 51 mm wide, using a dual-slot design with 2x 8-pin power connectors and a suggested PSU of 600 W. The NVIDIA card is longer at 304 mm, taller at 137 mm, and wider at 40 mm, also using a dual-slot design but with a single 16-pin power connector and no suggested PSU listed. The AMD card has a TDP of 260 W, while the NVIDIA card has a TDP of 415 W, a significant gap in power draw.

Specification Differences

The recorded specifications reveal several clear differences between the two GPUs. The AMD Radeon RX 7900 GRE has a base clock of 1287 MHz, a boost clock of 2245 MHz, and a game clock of 1880 MHz. The NVIDIA GeForce RTX 5080 SUPER has a higher base clock of 2295 MHz and a higher boost clock of 2617 MHz, with no game clock listed. The memory clock for the AMD card is 2250 MHz with 18 Gbps effective, while the NVIDIA card runs at 2000 MHz with 32 Gbps effective.

The shading unit count is drastically different: the AMD card has 5120 shading units, while the NVIDIA card has 10752, more than double. The TMU count is 320 for AMD and 336 for NVIDIA, while the ROP count is 160 for AMD and 112 for NVIDIA. The pixel rate for the AMD card is 359.2 GPixel/s, higher than the NVIDIA card's 293.1 GPixel/s. The texture rate is 718.4 GTexel/s for AMD and 879.3 GTexel/s for NVIDIA.

The bus interface also differs: the AMD card uses PCIe 4.0 x16, while the NVIDIA card uses PCIe 5.0 x16. Display outputs vary as well, with the AMD card offering 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the NVIDIA card offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. The launch MSRP for the AMD Radeon RX 7900 GRE is 549 USD, and for the NVIDIA GeForce RTX 5080 SUPER it is 999 USD.

The Verdict

The benchmark data strongly favors the AMD Radeon RX 7900 GRE in the single available head-to-head test. The AMD card's 56.6% lead in 3DMark Steel Nomad DX12 is a decisive margin, and its 77th percentile ranking among all GPUs, with an average benchmark score of 32456, contrasts sharply with the NVIDIA card's 19th percentile ranking and average score of 3075. Based strictly on recorded measurements, the AMD Radeon RX 7900 GRE delivers the higher performance in the tested workload.

However, the NVIDIA GeForce RTX 5080 SUPER has notable specification advantages that are not reflected in the Steel Nomad result. Its higher shading unit count of 10752, larger 24 GB memory pool, faster GDDR7 memory with 1.02 TB/s bandwidth, and inclusion of 336 tensor cores position it as a more capable part for certain tasks, particularly those that leverage tensor operations or require large memory capacities. Its FP32 throughput of 56.28 TFLOPS also exceeds the AMD card's 45.98 TFLOPS.

The data indicates that the AMD card wins the only direct benchmark comparison, but the NVIDIA card wins on raw compute specifications and memory capacity. Users prioritizing the specific DX12 workload measured should select the AMD card. Users needing tensor cores or higher memory bandwidth may prefer the NVIDIA card based on its specification sheet, though its recorded benchmark score is significantly lower.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins in the 3DMark Steel Nomad DX12 benchmark, posting a score of 4814 versus 3075 for the NVIDIA card, a 56.6% advantage. This suggests the AMD architecture is more effective at this specific rendering task. The AMD card also wins on pixel rate, delivering 359.2 GPixel/s compared to 293.1 GPixel/s for NVIDIA, and on ROP count with 160 versus 112. Its lower TDP of 260 W compared to 415 W also indicates higher efficiency per watt in the recorded data.

The NVIDIA GeForce RTX 5080 SUPER wins on several specification fronts. It has more than double the shading units (10752 vs 5120), higher texture rate (879.3 GTexel/s vs 718.4 GTexel/s), and higher FP32 performance (56.28 TFLOPS vs 45.98 TFLOPS). Its memory subsystem is superior on paper, with 24 GB of GDDR7 memory and 1.02 TB/s bandwidth versus 16 GB of GDDR6 and 576.0 GB/s. The inclusion of 336 tensor cores gives it a capability the AMD card lacks entirely.

The AMD card wins in the only recorded benchmark and on pixel throughput and power efficiency. The NVIDIA card wins on compute density, memory capacity and bandwidth, and tensor-specific features. The choice between them depends on whether the user prioritizes the measured DX12 performance of the AMD card or the specification advantages of the NVIDIA card.
