AMD Radeon RX 7400 vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the AMD Radeon RX 7400, while the NVIDIA N1 20SM currently has no benchmark entries. This asymmetry shapes the comparison: the RX 7400 has measurable scores across eight tests, whereas the N1 20SM sits at an average benchmark score of 0 with no individual test results. Consequently, all head-to-head comparisons rely on the RX 7400's absolute scores and its position against other GPUs in the database.

The AMD Radeon RX 7400 delivers its strongest showing in PassMark G3D, scoring 11,897, which places it in the 17th percentile of all GPUs. Its average benchmark score across all tests is 2,467. The nearest rivals in the database provide context: the AMD Radeon 8040S averages 2,440 (1.1% behind), the NVIDIA GeForce 710M averages 2,433 (1.4% behind), the Intel HD Graphics 610 averages 2,425 (1.8% behind), and the NVIDIA GeForce GT 710M averages 2,422 (1.9% behind). These narrow margins indicate the RX 7400 sits at the top of a tightly clustered group of low-end performers.

In DirectX 9 workloads, the RX 7400 scores 176 on PassMark, which is its highest API-specific result. DirectX 11 yields a score of 97, while DirectX 10 drops to 59. DirectX 12 produces the lowest API score at 44. The compute-oriented PassMark GPU Compute test records 5,152, and the 2D graphics test scores 1,209. In 3DMark Steel Nomad DX12, the RX 7400 reaches 1,103.

Because the N1 20SM has no benchmark data, the database cannot confirm any single win for either card. The wins counter shows 0 for both items. The practical interpretation is that the RX 7400 has verified performance figures, while the N1 20SM's capabilities remain unmeasured in this database.

The percentile gap is stark: the RX 7400 ranks in the 17th percentile of all GPUs, while the N1 20SM is listed at the 50th percentile despite having no scores. This percentile value for the N1 20SM appears to be a placeholder rather than a result of testing, as an average score of 0 cannot produce a median ranking in any meaningful benchmark distribution.

Architecture Differences

The AMD Radeon RX 7400 uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, part of the Navi III (RX 7000) generation. It is fabricated on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per mm². The NVIDIA N1 20SM uses the GB20B chip on Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation, built on a 5 nm process at TSMC. Its die size is 382 mm², though transistor count and density are not recorded.

The RX 7400 has 1,792 shading units, 112 texture mapping units, 64 raster output units, and 28 ray tracing cores. The N1 20SM has 2,560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The RX 7400 has no tensor cores listed, which aligns with its gaming-focused RDNA design. The N1 20SM's 80 tensor cores indicate a compute-oriented architecture.

Clock behavior differs substantially. The RX 7400 runs at a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz. Its memory clock is 2250 MHz, translating to 18 Gbps effective. The N1 20SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with no game clock listed. Its memory clock is 1067 MHz, or 8.5 Gbps effective.

Memory configurations diverge sharply. The RX 7400 uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. Despite having four times the memory capacity, the N1 20SM has slightly lower bandwidth due to slower effective memory speed.

Compute throughput also differs. The RX 7400 achieves 16.49 TFLOPS FP32 and 32.97 TFLOPS FP16 (2:1 ratio). The N1 20SM achieves 12.01 TFLOPS FP32 and 12.01 TFLOPS FP16 (1:1 ratio). Pixel rates favor the RX 7400 at 147.2 GPixel/s versus 56.30 GPixel/s for the N1 20SM. Texture rates favor the N1 20SM at 375.4 GTexel/s versus 257.6 GTexel/s for the RX 7400.

The RX 7400 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, indicating no traditional graphics API support is recorded. The RX 7400 uses a PCIe 4.0 x8 interface, while the N1 20SM uses PCIe 5.0 x16. Display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1 for the RX 7400, versus 1x HDMI for the N1 20SM.

Power delivery is another contrast. The RX 7400 has a TDP of 43 W, uses a 1x 6-pin power connector, and suggests a 200 W PSU. It is dual-slot. The N1 20SM has unknown TDP, no power connectors, and is an IGP (integrated graphics processor) form factor.

The Verdict

The data presents a clear split. The AMD Radeon RX 7400 is a tested, shipping discrete graphics card with verified performance across multiple benchmarks. Its 17th percentile ranking and average score of 2,467 place it in the lower tier of the database, but it has real numbers. The NVIDIA N1 20SM has no benchmark results, no API support listed, and an average score of 0, despite its 50th percentile designation.

For any workload requiring measured graphics performance, the RX 7400 is the only option with evidence. Its DirectX 9 score of 176 and G3D score of 11,897 show it can handle legacy and general 3D tasks. Its DirectX 12 score of 44 is weak, but it exists. The N1 20SM offers no such data.

The N1 20SM's architecture suggests a different purpose. Its 128 GB of LPDDR5X memory, 80 tensor cores, and 256-bit bus point to integrated or compute scenarios, not traditional gaming. The lack of DirectX, OpenGL, and Vulkan support confirms this: the database records no graphics API compatibility. The RX 7400, by contrast, supports modern APIs and has a dual-slot cooler with a 6-pin connector.

Buyers seeking a discrete GPU for gaming or general graphics should choose the RX 7400, as it is the only card with measurable performance. The N1 20SM's role appears to be compute or embedded, but without benchmark data, its real-world capability cannot be assessed from this database.

Where Each One Wins

The AMD Radeon RX 7400 wins in every category where numbers exist. It has higher FP32 throughput at 16.49 TFLOPS versus 12.01 TFLOPS, nearly three times the FP16 throughput at 32.97 TFLOPS versus 12.01 TFLOPS, and more than double the pixel rate at 147.2 GPixel/s versus 56.30 GPixel/s. Its memory bandwidth is slightly higher at 288.0 GB/s versus 273.2 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for all three. It has a lower base clock but a higher game clock, and it uses a standard PCIe 4.0 x8 slot with a 6-pin power connector.

The NVIDIA N1 20SM wins on raw capacity and configuration. It has 128 GB of memory versus 8 GB, a 256-bit bus versus 128-bit, 2,560 shading units versus 1,792, 160 TMUs versus 112, and 80 tensor cores versus none. Its texture rate is higher at 375.4 GTexel/s versus 257.6 GTexel/s. It runs on a 5 nm process versus 6 nm, has a larger die at 382 mm² versus 204 mm², uses a faster PCIe 5.0 x16 interface, and has a higher boost clock at 2346 MHz versus 2300 MHz. It requires no power connectors and is an IGP, whereas the RX 7400 needs a 6-pin connector and occupies a dual slot.

Use-case segmentation follows these data. For gaming, DirectX workloads, and traditional graphics rendering, the RX 7400 is the functional choice because it has API support and benchmark scores. For memory-heavy compute tasks, tensor operations, or integrated deployments where 128 GB of unified memory is essential, the N1 20SM's specifications are superior, but its performance remains unverified. The RX 7400's 17th percentile ranking and average score of 2,467 confirm it as a low-end discrete card, while the N1 20SM's 50th percentile is unsupported by test data and should not be interpreted as a performance advantage.
