AMD Radeon RX 7400 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The recorded data positions the NVIDIA GeForce RTX 5070 Mobile as the dominant performer in this comparison. The RTX 5070 Mobile wins 6 of 7 head-to-head benchmark tests, with its average benchmark score of 29928 placing it in the 75th percentile of all GPUs. The AMD Radeon RX 7400, by contrast, sits in the 17th percentile with an average benchmark score of 2467. This is not a close contest in raw compute terms; the RTX 5070 Mobile delivers 71.1% higher Passmark G3D scores (20355 vs 11897) and nearly double the DirectX 11 performance (192 vs 97).

The RX 7400 does have one clear domain of superiority: 2D graphics. It wins the Passmark G2D test by 34.9% (1209 vs 896), indicating that for desktop composition, image processing, and general 2D workloads, the AMD part is faster. However, this single win does not offset the scale of the NVIDIA advantage in 3D rendering, compute, and API-specific tests. The RTX 5070 Mobile also leads in GPU compute by 37.8% (8279 vs 5152), which matters for non-graphics workloads such as encoding and scientific calculations.

The performance tier gap is further confirmed by the nearest rival data. The RX 7400's average score of 2467 places it just 1.1% above the AMD Radeon 8040S (2440) and 1.4% above the NVIDIA GeForce 710M (2433). These are low-end integrated and entry-level discrete parts. The RTX 5070 Mobile's average score of 29928 sits within 0.1% of the NVIDIA GeForce RTX 3070 Ti (29945) and 0.5% above the RTX 2080 Ti (29783). The data shows the RTX 5070 Mobile competes with previous-generation high-end desktop cards, while the RX 7400 competes with decade-old mobile GPUs.

For system builders, the choice is straightforward based on the data: the RTX 5070 Mobile is for users who need 3D rendering, modern API performance, and compute throughput. The RX 7400 is for users whose primary workload is 2D acceleration and who do not require competitive 3D or compute performance. The RTX 5070 Mobile also has a higher TDP (50 W vs 43 W), so the AMD part is more power-efficient per watt in simple workloads, but that efficiency does not translate into competitive 3D performance.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish. It is manufactured on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip on Blackwell 2.0 architecture. It is built on a 5 nm process at TSMC with 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0M per mm².

The transistor density difference is substantial: the RTX 5070 Mobile packs nearly twice the transistors per square millimeter (121.0M vs 65.2M). This allows NVIDIA to fit 4608 shading units, 144 TMUs, 36 RT cores, and 144 tensor cores into a smaller die. The RX 7400 has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, plus no tensor cores (null in the database). The RX 7400 has more ROPs (64 vs 48) and a higher pixel rate (147.2 GPixel/s vs 68.40 GPixel/s), but the NVIDIA part has more of nearly every other compute resource.

The memory subsystems also reflect different approaches. Both use an 8 GB frame buffer on a 128-bit bus, but the RX 7400 uses GDDR6 at 18 Gbps effective, delivering 288.0 GB/s. The RTX 5070 Mobile uses GDDR7 at 24 Gbps effective, delivering 384.0 GB/s. The NVIDIA part offers 33.3% more memory bandwidth, which benefits high-resolution textures and data-heavy workloads.

The RX 7400 is a discrete dual-slot card with a 1x 6-pin power connector and a 200 W suggested PSU. The RTX 5070 Mobile is an integrated graphics processor (IGP) with no power connectors and no suggested PSU listed. The RX 7400 uses PCIe 4.0 x8, while the RTX 5070 Mobile uses PCIe 5.0 x16, giving the NVIDIA part twice the PCIe lanes on a newer standard. The RX 7400 has fixed display outputs (1x HDMI 2.1a and 3x DisplayPort 2.1), while the RTX 5070 Mobile's outputs are portable device dependent.

Specification Differences

The clock speeds differ significantly. The RX 7400 has a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz. The RTX 5070 Mobile has a base clock of 907 MHz and a boost clock of 1425 MHz, with no game clock listed. The AMD part runs at higher frequencies, but the NVIDIA part compensates with more compute units.

The FP32 compute figures are counterintuitive: the RX 7400 delivers 16.49 TFLOPS, while the RTX 5070 Mobile delivers 13.13 TFLOPS. The AMD part is 25.6% higher in raw FP32 throughput. However, benchmark results show the RTX 5070 Mobile wins decisively in real-world tests, indicating that architectural efficiency and driver optimization matter more than peak theoretical throughput. The FP16 figures further separate them: the RX 7400 delivers 32.97 TFLOPS at a 2:1 ratio, while the RTX 5070 Mobile delivers 13.13 TFLOPS at a 1:1 ratio.

The texture rates are close: the RX 7400 delivers 257.6 GTexel/s versus the RTX 5070 Mobile's 205.2 GTexel/s, a 25.5% advantage for AMD. The pixel rates diverge more sharply, with the RX 7400 at 147.2 GPixel/s versus 68.40 GPixel/s, a 115% advantage for AMD. Despite these fill-rate advantages, the NVIDIA part wins the 3D benchmark by a wide margin, suggesting that geometry processing, ray tracing, and driver-level optimizations play the decisive role.

The RX 7400 was released on 2025-08-07, while the RTX 5070 Mobile was released earlier on 2025-04-14. The RX 7400's predecessor is Navi II and successor is Navi IV. The RTX 5070 Mobile's predecessor is GeForce 40 Mobile, with no successor listed. The RTX 5070 Mobile has an active production status, while the RX 7400's status is not listed.

Head-to-Head Benchmarks

The head-to-head results show a consistent NVIDIA advantage across all 3D and compute tests. The largest gap is in DirectX 10, where the RTX 5070 Mobile scores 129 versus the RX 7400's 59, a 54.3% difference. DirectX 12 shows a similar pattern: 93 versus 44, a 52.7% gap. DirectX 11 is close behind at 49.5% (192 vs 97). These results indicate that the NVIDIA architecture scales better across API generations, from legacy DirectX 9 to modern DirectX 12.

The Passmark G3D test, which aggregates overall 3D performance, shows the RTX 5070 Mobile at 20355 versus 11897, a 41.6% advantage. The GPU compute test shows 8279 versus 5152, a 37.8% advantage. Even the closest 3D gap, DirectX 9, shows the NVIDIA part ahead by 17.8% (214 vs 176). This suggests that the RTX 5070 Mobile maintains its lead even in older APIs where the RX 7400's higher clock speeds might be expected to help.

The single AMD win is in Passmark G2D, where the RX 7400 scores 1209 versus 896, a 34.9% advantage. This is the only test where the RX 7400 leads, and it is a substantial lead. The G2D test measures 2D graphics operations such as bitmap rendering, window management, and basic desktop acceleration, areas where the RX 7400's higher pixel rate (147.2 GPixel/s) likely contributes.

The benchmark averages tell the broader story. The RX 7400's average benchmark score of 2467 is dragged down by low DirectX scores (44 to 176), while its G2D score of 1209 is its strongest result. The RTX 5070 Mobile's average of 29928 is driven by strong DirectX scores (93 to 214) and a massive G3D score of 20355, despite a weaker G2D score of 896. The NVIDIA part also has Geekbench OpenCL and Vulkan scores of 122238 and 116960 respectively, which are not available for the RX 7400.

Where Each One Wins

The RTX 5070 Mobile wins in every 3D rendering scenario covered by the benchmarks. DirectX 10, 11, and 12 tests show it leading by 49.5% to 54.3%, making it the clear choice for modern games and 3D applications. The Passmark G3D score of 20355 confirms this is a high-performance part, comparable to desktop GPUs like the RTX 3070 Ti (29945 average, only 0.1% faster) and RTX 2080 Ti (29783, 0.5% slower). Users running 3D modeling, video editing with GPU acceleration, or any DirectX-based game should select the RTX 5070 Mobile.

The RTX 5070 Mobile also wins in compute workloads. Its GPU compute score of 8279 is 37.8% higher than the RX 7400's 5152. This covers general-purpose GPU computing, which is used in rendering, physics simulations, machine learning inference, and cryptocurrency mining. The presence of 144 tensor cores gives it a structural advantage for AI-accelerated tasks, though the benchmark data does not include a dedicated tensor test.

The RX 7400 wins exclusively in 2D graphics. Its G2D score of 1209 versus 896 represents a 34.9% advantage. This makes it suited for office productivity, desktop environments, image viewing, and 2D design software. Its higher pixel rate (147.2 GPixel/s) and texture rate (257.6 GTexel/s) support this strength. However, the RX 7400's 17th percentile ranking and nearest rival list (AMD Radeon 8040S, NVIDIA GeForce 710M, Intel HD Graphics 610) show it belongs to the entry-level segment. For any workload that involves 3D acceleration, the RTX 5070 Mobile's 75th percentile ranking and rival list (RTX 3070 Ti, RTX 2080 Ti, RX 6800) make it the superior choice.

The power envelope favors the AMD part slightly, with a 43 W TDP versus 50 W. This makes the RX 7400 more suitable for low-power systems where 2D performance is the priority. The RTX 5070 Mobile's higher TDP is justified by its benchmark performance, delivering 6 wins versus 1 in head-to-head tests. The data does not support any scenario where the RX 7400 is preferable for 3D, gaming, or compute workloads.
