AMD Radeon RX 7400 OEM vs NVIDIA GeForce RTX 4070 Comparison

Where Each One Wins

The recorded data splits this pairing into two entirely different performance classes. The NVIDIA GeForce RTX 4070 holds every benchmark win in the database, with no recorded wins for the AMD Radeon RX 7400 OEM. The RTX 4070 sits at the 81st percentile among all GPUs, while the RX 7400 OEM sits at the 50th percentile. That percentile gap alone indicates the RTX 4070 belongs to a higher performance tier, and the benchmark scores confirm it.

The RTX 4070 delivers a Passmark G3D score of 26,927, a Passmark GPU Compute score of 14,720, a Geekbench OpenCL score of 154,858, and a Geekbench Vulkan score of 174,152. The RX 7400 OEM has no recorded benchmark scores in the database, so every comparison must rely on architectural and specification differences. The data shows the RTX 4070 is the clear winner in every measurable category where numbers exist.

For use-case analysis, the RTX 4070's 12 GB GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth positions it for higher-resolution textures and memory-heavy workloads. Its 46 RT cores and 184 tensor cores indicate hardware-accelerated ray tracing and AI processing capabilities. The RX 7400 OEM, with 8 GB GDDR6 on a 128-bit bus and 172.8 GB/s bandwidth, targets a lower bandwidth tier. Its 28 RT cores provide ray tracing support but with fewer units than the NVIDIA part.

The RX 7400 OEM does hold advantages in specific physical and power characteristics. Its 55 W TDP versus the RTX 4070's 200 W TDP, combined with a single-slot form factor and 167 mm length, makes it a low-power, compact option. The RTX 4070 requires a dual-slot design at 240 mm length, 110 mm height, and 40 mm width. These differences suggest the RX 7400 OEM suits constrained builds where power and space are the primary constraints, while the RTX 4070 suits performance-oriented systems.

Architecture Differences

The two GPUs come from different manufacturers, architectures, and process nodes. The AMD Radeon RX 7400 OEM uses the Navi 33 chip on RDNA 3.0 architecture, codenamed Hotpink Bonefish, part of the Navi III (RX 7000) generation. It is built on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². The NVIDIA GeForce RTX 4070 uses the AD104 chip on Ada Lovelace architecture, part of the GeForce 40 generation. It is built on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8 million per mm². The RTX 4070 packs nearly 2.7 times more transistors into a die that is only about 44% larger, reflecting a much higher density design.

Shader resources differ substantially. The RX 7400 OEM has 1,792 shading units, 112 texture mapping units, and 64 raster operation units. The RTX 4070 has 5,888 shading units, 184 TMUs, and 64 ROPs. The RTX 4070 provides over three times the shading units and about 64% more TMUs, while ROP counts match at 64. The RTX 4070 also includes 46 RT cores and 184 tensor cores; the RX 7400 OEM has 28 RT cores and no tensor cores recorded.

Clock speeds tell a different story in raw terms. The RX 7400 OEM lists a base clock of 330 MHz and a boost clock of 1,100 MHz, while the RTX 4070 lists a base clock of 1,920 MHz and a boost clock of 2,475 MHz. The RTX 4070's much higher clocks combine with its larger shader count to produce a massive compute gap. The FP32 throughput on the RX 7400 OEM is 7.885 TFLOPS, while the RTX 4070 reaches 29.15 TFLOPS, a difference of roughly 3.7 times. Both list FP16 at the same 1:1 ratio as FP32. Pixel rates are 70.40 GPixel/s for the AMD part versus 158.4 GPixel/s for the NVIDIA part. Texture rates are 123.2 GTexel/s versus 455.4 GTexel/s.

Memory architecture differs in capacity, type, and bandwidth. The RX 7400 OEM uses 8 GB GDDR6 at 1,350 MHz (10.8 Gbps effective) on a 128-bit bus for 172.8 GB/s. The RTX 4070 uses 12 GB GDDR6X at 1,313 MHz (21 Gbps effective) on a 192-bit bus for 504.2 GB/s. The RTX 4070 delivers nearly three times the memory bandwidth.

Interface and connectivity also differ. The RX 7400 OEM uses PCIe 4.0 x8, while the RTX 4070 uses PCIe 4.0 x16. Display outputs favor the AMD card with 1x HDMI 2.1a and 3x DisplayPort 2.1, versus the NVIDIA card with 1x HDMI 2.1 and 3x DisplayPort 1.4a. API support matches: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Power delivery and physical design diverge sharply. The RX 7400 OEM has a 55 W TDP, a single 6-pin power connector, and a 250 W suggested PSU. The RTX 4070 has a 200 W TDP, a single 16-pin power connector, and a 550 W suggested PSU. The RX 7400 OEM is single-slot; the RTX 4070 is dual-slot.

Release timing and status also differ. The RX 7400 OEM launched on 2025-08-07 with no production status recorded. The RTX 4070 launched on 2023-04-11 and is marked end-of-life. The AMD part succeeds the Navi II generation and precedes Navi IV. The NVIDIA part succeeds GeForce 30 and precedes GeForce 50.

Head-to-Head Benchmarks

The database records benchmarks only for the RTX 4070, with no entries for the RX 7400 OEM. The RTX 4070's strongest results come from Geekbench and Passmark suites. In Geekbench Vulkan, it scores 174,152. In Geekbench OpenCL, it scores 154,858. The Passmark G3D result of 26,927 and Passmark GPU Compute result of 14,720 show solid general and compute performance. The Passmark DirectX tests show 320 for DirectX 9, 244 for DirectX 11, 139 for DirectX 10, and 103 for DirectX 12. The Passmark G2D score is 1,164.

The RTX 4070's average benchmark score is 37,648. Its nearest rival, the NVIDIA Tesla P4, scores 37,628, a delta of 0.1%, meaning the RTX 4070 is essentially tied with that product. The AMD Radeon RX Vega 56 scores 37,507, a 0.4% gap. The RTX 4080 Mobile scores 38,135, leading the RTX 4070 by 1.3%. The AMD Radeon PRO W6400 trails at 37,157, a 1.3% deficit. These deltas show the RTX 4070 sits in a tightly packed cluster of similar-performing GPUs, all within roughly 1.3% of each other.

With no recorded benchmark data for the RX 7400 OEM, the head-to-head comparison relies on the architectural gaps detailed above. The FP32 throughput difference of 3.7 times, memory bandwidth difference of 2.9 times, and shading unit difference of 3.3 times all point to the same conclusion: the RTX 4070 dominates in every performance metric where numbers exist.

The Verdict

The data shows a decisive performance hierarchy. The NVIDIA GeForce RTX 4070 is the stronger GPU in every measured or spec-derived dimension. Its 29.15 TFLOPS FP32 versus 7.885 TFLOPS, its 504.2 GB/s versus 172.8 GB/s memory bandwidth, and its 5,888 shading units versus 1,792 all confirm a multi-generation class gap. The 81st percentile standing versus the 50th percentile standing reinforces that the RTX 4070 belongs in a higher performance bracket.

The AMD Radeon RX 7400 OEM has no recorded benchmark scores, so its case rests entirely on physical and power advantages. Its 55 W TDP versus 200 W, its single-slot 167 mm design versus dual-slot 240 mm, and its 250 W suggested PSU versus 550 W make it the appropriate choice for compact, low-power systems. Its newer DisplayPort 2.1 outputs and HDMI 2.1a also provide a display connectivity edge over the RTX 4070's DisplayPort 1.4a and HDMI 2.1.

For users prioritizing raw performance, ray tracing capability, AI compute via tensor cores, and higher memory bandwidth, the RTX 4070 is the clear selection. It offers 12 GB GDDR6X, 46 RT cores, and 184 tensor cores. For users prioritizing minimal power draw, single-slot physical footprint, and newer display output standards, the RX 7400 OEM fits that niche. The release dates also matter: the RX 7400 OEM launched on 2025-08-07, while the RTX 4070 launched on 2023-04-11 and is already marked end-of-life. The RTX 4070's successor, GeForce 50, is already recorded, while the RX 7400 OEM's successor, Navi IV, has not yet arrived. The verdict from the recorded data is straightforward: the RTX 4070 wins on performance comprehensively, while the RX 7400 OEM wins on efficiency and form factor.
