AMD Radeon RX 7400 vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The only shared benchmark in the database is 3DMark Steel Nomad DX12, and the results are decisive. The NVIDIA GeForce RTX 5080 SUPER scores 3075 points, while the AMD Radeon RX 7400 scores 1103 points. That gives the RTX 5080 SUPER a 64.1% lead, a margin so large that the two cards are not competing in the same performance class. The RTX 5080 SUPER wins the only head-to-head test, and the database records zero benchmark wins for the RX 7400.

The RX 7400 has its own set of recorded scores across multiple legacy and compute workloads. In PassMark DirectX 9 it delivers 176 points, its strongest legacy API result. DirectX 11 shows 97 points, DirectX 10 drops to 59 points, and DirectX 12 falls to 44 points. The RX 7400 also records a PassMark G3D score of 11897, a G2D score of 1209, and a GPU compute score of 5152. Its average benchmark score across all recorded tests is 2467.

The RTX 5080 SUPER, by contrast, has only the one Steel Nomad entry in the database, so its average benchmark score is identical to that result: 3075. Comparing averages directly, the RTX 5080 SUPER sits 24.7% above the RX 7400's average score of 2467. But that comparison is misleading, because the RX 7400's average is pulled down by its low legacy DirectX scores. In the one test where both cards appear, the RTX 5080 SUPER is nearly three times faster.

Percentile placement reinforces the gulf. The RX 7400 sits at the 17th percentile of all GPUs in the database. The RTX 5080 SUPER sits at the 19th percentile. Despite the massive delta in raw scores, both cards rank near the same low percentile tier, which indicates that the database's GPU population is dominated by far faster parts. Relative to their nearest recorded rivals, both cards are clustered tightly. The RX 7400's nearest rival, the AMD Radeon 8040S, averages 2440, just 1.1% behind. The NVIDIA GeForce 710M trails by 1.4%, the Intel HD Graphics 610 by 1.8%, and the NVIDIA GeForce GT 710M by 1.9%. The RTX 5080 SUPER's nearest rivals are similarly close: the Intel Arc Pro B60 leads it by 3.4%, the NVIDIA Quadro P1000 leads by 2.8%, and the NVIDIA GeForce 820A trails by 3.1%, with the GeForce GTX 860M 3.6% behind.

Architecture Differences

The two cards come from different manufacturers, different architectures, and different process nodes. The AMD Radeon RX 7400 uses the Navi 33 chip built on RDNA 3.0, codenamed "Hotpink Bonefish," and belongs to the Navi III (RX 7000) generation. It is fabricated by TSMC on a 6 nm process. The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip built on Blackwell 2.0 and belongs to the GeForce 50 generation. It is also fabricated by TSMC, but on a 5 nm process. The node difference is small in absolute terms, but the transistor counts are not. The RX 7400 packs 13,300 million transistors on a 204 mm² die, for a transistor density of 65.2 million per square millimeter. The RTX 5080 SUPER packs 45,600 million transistors on a 378 mm² die, for a density of 120.6 million per square millimeter. That is roughly 3.4 times the transistor count and nearly double the density.

Shader resources differ by an even wider margin. The RX 7400 has 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. It includes 28 ray tracing cores and no tensor cores. The RTX 5080 SUPER has 10752 shading units, 336 TMUs, and 112 ROPs. It includes 84 ray tracing cores and 336 tensor cores. The shading unit count is exactly six times higher on the NVIDIA part. Tensor cores are a structural advantage for the RTX 5080 SUPER, enabling AI-accelerated workloads that the RX 7400 cannot address with dedicated hardware.

Compute throughput numbers follow the same pattern. The RX 7400 delivers 16.49 TFLOPS of FP32 and 32.97 TFLOPS of FP16 using a 2:1 ratio. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 and 56.28 TFLOPS of FP16 at a 1:1 ratio. The NVIDIA card is 3.4 times faster in FP32 and 1.7 times faster in FP16, and it does not halve its FP16 rate to get there. Pixel fill rate on the RTX 5080 SUPER is 293.1 GPixel/s versus 147.2 GPixel/s on the RX 7400, roughly double. Texture fill rate is 879.3 GTexel/s versus 257.6 GTexel/s, a 3.4 times advantage.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That means feature-level API parity, but the underlying hardware capabilities are far apart. The RX 7400 uses a PCIe 4.0 x8 bus interface, while the RTX 5080 SUPER uses PCIe 5.0 x16. The NVIDIA card has double the lane count and a newer bus generation, which matters for data transfer in bandwidth-sensitive workloads.

Where Each One Wins

The RTX 5080 SUPER wins every category where the two overlap. In the only direct benchmark, 3DMark Steel Nomad DX12, it beats the RX 7400 by 64.1%. That is a pure rasterization and DX12 workload, so the NVIDIA card's advantage there is not dependent on ray tracing or tensor cores. Its FP32 throughput of 56.28 TFLOPS versus 16.49 TFLOPS gives it a 3.4 times raw compute advantage, which shows up in any shader-bound scenario. The 879.3 GTexel/s texture rate versus 257.6 GTexel/s means texture-heavy scenes will run far faster. The 293.1 GPixel/s pixel rate versus 147.2 GPixel/s gives it a 2 times fill rate edge for high-resolution rendering.

The memory subsystem also favors the RTX 5080 SUPER. It has 24 GB of GDDR7 on a 256 bit bus, with 1.02 TB/s of bandwidth. The RX 7400 has 8 GB of GDDR6 on a 128 bit bus, with 288.0 GB/s of bandwidth. That is a 3.5 times bandwidth advantage and three times the capacity. For large textures, high resolutions, or data-heavy compute, the NVIDIA card has clear headroom. The RX 7400's 8 GB capacity is adequate for lighter loads, but the 128 bit bus and 288.0 GB/s bandwidth will bottleneck modern titles at high settings.

The RX 7400's strengths are narrower. Its 43 W TDP is dramatically lower than the RTX 5080 SUPER's 415 W, roughly one tenth of the power draw. It uses a single 6-pin power connector and a suggested 200 W PSU, while the RTX 5080 SUPER uses a 16-pin connector. The RX 7400 is a dual-slot card with no recorded dimensions, while the RTX 5080 SUPER measures 304 mm in length, 137 mm in height, and 40 mm in width. The RX 7400 is the more physically compact option. Its release date of August 7, 2025 is earlier than the RTX 5080 SUPER's December 31, 2025 date. The RX 7400 belongs to the Radeon RX 7000 series with a predecessor of Navi II and a successor of Navi IV, giving it a clear product lineage. The RTX 5080 SUPER has no recorded predecessor or successor in the database.
