AMD Radeon RX 7400 vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the AMD Radeon RX 7400 versus the NVIDIA GeForce RTX 5090 SE. The head-to-head record shows zero wins for either card, and no paired test scores are recorded. The RTX 5090 SE has an average benchmark score of 0, with an empty benchmark list and no nearest rivals on file. The RX 7400, by contrast, has a full set of recorded measurements across multiple DirectX and compute tests.

The RX 7400's strongest recorded result is in PassMark G3D, where it scores 11,897. Its PassMark G2D score is 1,209, which is modest for a discrete card. In DirectX 9, the card records 176, while DirectX 11 shows 97, DirectX 10 shows 59, and DirectX 12 shows 44. The GPU compute score is 5,152, and the 3DMark Steel Nomad DX12 result is 1,103. The average benchmark score across all recorded tests is 2,467.

Given the absence of paired data, direct percentage comparisons between these two cards are not possible from the recorded measurements. The RTX 5090 SE's percentile ranking is 50, which places it at the midpoint of all GPUs in the database, but this is based on no actual test scores. The RX 7400 sits at the 17th percentile, with an average score of 2,467. The nearest rivals for the RX 7400 are the AMD Radeon 8040S (average score 2,440, delta of 1.1%), the NVIDIA GeForce 710M (2,433, delta 1.4%), the Intel HD Graphics 610 (2,425, delta 1.8%), and the NVIDIA GeForce GT 710M (2,422, delta 1.9%). These deltas are all within 2%, indicating the RX 7400's recorded average is statistically close to those integrated and low-end mobile parts.

What the data does show is a massive gap in raw specifications that will translate to equally massive performance differences in any real workload. The RX 7400's 16.49 TFLOPS FP32 figure is roughly a quarter of the RTX 5090 SE's 66.94 TFLOPS. Memory bandwidth differs by a factor of more than four: 288.0 GB/s versus 1.34 TB/s. Texture rate is 257.6 GTexel/s against 1,045.9 GTexel/s, and pixel rate is 147.2 GPixel/s versus 380.3 GPixel/s. These are not close numbers, and any benchmark run would reflect that gap.

Architecture Differences

The RX 7400 uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename "Hotpink Bonefish." It belongs to the Navi III generation of the RX 7000 series and succeeds Navi II. The RTX 5090 SE uses the GB202 chip on Blackwell 2.0 architecture, part of the GeForce 50 generation, succeeding GeForce 40. Both chips come from TSMC, but they use different process nodes: the RX 7400 is on 6 nm, while the RTX 5090 SE is on 5 nm.

Transistor counts reflect the scale difference. The RX 7400 packs 13,300 million transistors on a 204 mm² die, giving a density of 65.2M per mm². The RTX 5090 SE contains 92,200 million transistors on a 750 mm² die, with a density of 122.9M per mm². The RTX 5090 SE is physically much larger and electronically much denser.

The RX 7400 has 1,792 shading units, 112 TMUs, and 64 ROPs. It includes 28 ray tracing cores but no tensor cores, meaning no dedicated AI acceleration hardware. The RTX 5090 SE has 14,080 shading units, 440 TMUs, and 160 ROPs. It includes 110 ray tracing cores and 440 tensor cores, giving it dedicated hardware for both ray tracing and AI workloads. The FP16 performance ratio differs: the RX 7400 achieves 32.97 TFLOPS FP16 via a 2:1 ratio, while the RTX 5090 SE achieves 66.94 TFLOPS FP16 at a 1:1 ratio, meaning both FP16 and FP32 run at the same throughput.

Memory subsystems are entirely different generations. The RX 7400 uses 8 GB of GDDR6 on a 128-bit bus at 18 Gbps effective, producing 288.0 GB/s. The RTX 5090 SE uses 24 GB of GDDR7 on a 384-bit bus at 28 Gbps effective, producing 1.34 TB/s. The bus width is three times larger, the memory type is newer, and the capacity is three times higher.

The Verdict

The data points to two cards built for entirely different purposes. The RX 7400 is a low-power part: 43 W TDP, 8 GB of GDDR6, and no tensor cores. Its recorded benchmark scores place it at the 17th percentile, with an average score of 2,467, sitting alongside integrated graphics and low-end mobile GPUs like the Intel HD Graphics 610 and NVIDIA GeForce GT 710M. The RTX 5090 SE is a high-end part: 500 W TDP, 24 GB of GDDR7, 440 tensor cores, and a 50th percentile ranking. Every specification in the database favors the RTX 5090 SE by a wide margin.

The RX 7400 should be chosen for systems where power draw is the primary constraint. Its 43 W TDP and 200 W suggested PSU make it suitable for small form factor builds or office machines that need basic DirectX 12 support. Its 16.49 TFLOPS FP32 is enough for light 1080p workloads, and its 8 GB GDDR6 is adequate for modest texture loads. The lack of tensor cores means no AI acceleration, and the 288.0 GB/s bandwidth will limit higher-resolution gaming.

The RTX 5090 SE should be chosen for workloads that demand maximum compute throughput. Its 66.94 TFLOPS FP32, 1.34 TB/s bandwidth, and 24 GB VRAM support high-resolution textures, large datasets, and compute-heavy tasks. The 440 tensor cores enable AI acceleration, and the 110 ray tracing cores provide dedicated RT hardware. The 500 W TDP and 900 W suggested PSU require a serious power supply, and the 267 mm length requires a case with adequate clearance.

There is no recorded performance data for the RTX 5090 SE, so the verdict rests on architectural specifications and the RX 7400's measured scores. The RX 7400's nearest rivals are all within 2% of its average score, which indicates its performance class is firmly in the entry-level segment. The RTX 5090 SE's specification sheet places it in a completely different tier. The choice is not about which card is better in absolute terms; it is about which workloads each card can physically handle.

Where Each One Wins

The RX 7400 wins on power efficiency. Its 43 W TDP is a fraction of the RTX 5090 SE's 500 W, and its 200 W suggested PSU means it can run in systems that cannot support a 900 W power supply. It also uses a single 6-pin connector instead of a 16-pin connector, which simplifies cabling in compact builds. Its 6 nm process is older, but the small die size of 204 mm² keeps manufacturing costs structurally lower, though price is not recorded in the database.

The RX 7400 wins on physical footprint flexibility. Its dimensions are not recorded, but the dual-slot design and low power draw suggest compatibility with small cases. The RTX 5090 SE requires 267 mm of length and 40 mm of width, which eliminates many smaller chassis. The RX 7400's 8 GB GDDR6 and 128-bit bus are sufficient for basic tasks, and its 28 ray tracing cores provide entry-level RT support.

The RTX 5090 SE wins on every compute metric. FP32 throughput is 66.94 TFLOPS versus 16.49 TFLOPS, a fourfold advantage. FP16 throughput is 66.94 TFLOPS versus 32.97 TFLOPS, a twofold advantage. Texture rate is 1,045.9 GTexel/s versus 257.6 GTexel/s. Pixel rate is 380.3 GPixel/s versus 147.2 GPixel/s. Memory bandwidth is 1.34 TB/s versus 288.0 GB/s.

The RTX 5090 SE wins on memory capacity and type. Its 24 GB GDDR7 is triple the RX 7400's 8 GB GDDR6, and the 384-bit bus provides more than four times the bandwidth. This makes it suitable for large datasets and high-resolution textures that would exhaust the RX 7400's memory. The RTX 5090 SE also wins on AI acceleration, with 440 tensor cores versus none on the RX 7400. Ray tracing hardware is also denser: 110 cores versus 28.

The RTX 5090 SE wins on connectivity. Its PCIe 5.0 x16 interface doubles both the generation and lane count of the RX 7400's PCIe 4.0 x8. Its display outputs are newer revisions: HDMI 2.1b versus 2.1a, and DisplayPort 2.1b versus 2.1. The RTX 5090 SE also has a recorded production status of active, while the RX 7400's status is unknown.

The RTX 5090 SE wins on transistor density and total transistor count. Its 92,200 million transistors on 750 mm² produce a density of 122.9M per mm², nearly double the RX 7400's 65.2M per mm². The 13,300 million transistor count on the RX 7400 is a fraction of the RTX 5090 SE's total. In workloads that scale with transistor count, such as compute and AI inference, the RTX 5090 SE has a structural advantage.

The RX 7400 wins on release timing, having launched on 2025-08-07, earlier than the RTX 5090 SE's 2025-12-31 date. In terms of recorded benchmark data, the RX 7400 is the only one of the two with actual test scores. The RTX 5090 SE has no benchmark entries, no nearest rivals, and an average score of zero. For users who rely on measured performance data, the RX 7400 is the only card with verifiable results in the database.
