AMD Radeon RX 7400 vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the AMD Radeon RX 7400 and the NVIDIA N1 16SM, and the NVIDIA N1 16SM has no recorded benchmark scores of its own. The AMD Radeon RX 7400, by contrast, has eight recorded test results. Its average benchmark score is 2467, placing it at the 17th percentile of all GPUs in the database.

The RX 7400 delivers its strongest result in PassMark G3D with a score of 11897. Its PassMark G2D score is 1209, which is a modest result. Compute performance is recorded at 5152 in PassMark GPU Compute. In 3DMark Steel Nomad DX12, the card scores 1103. The legacy DirectX tests show a wide spread: PassMark DirectX 9 returns 176, DirectX 11 returns 97, DirectX 10 returns 59, and DirectX 12 returns 44.

Since the N1 16SM has no benchmark entries, direct score comparisons cannot be made. The nearest recorded rivals for the RX 7400, based on average score, are the AMD Radeon 8040S at 2440 (1.1% slower), the NVIDIA GeForce 710M at 2433 (1.4% slower), the Intel HD Graphics 610 at 2425 (1.8% slower), and the NVIDIA GeForce GT 710M at 2422 (1.9% slower). These deltas are small, indicating that the RX 7400 sits close to a cluster of low-end parts in the database's aggregate ranking.

The N1 16SM holds a 50th percentile position across all GPUs, but that percentile is not supported by any test scores in the record, so it cannot be cross-checked against the RX 7400's measured results. Any comparison between the two parts must rely on architectural specifications rather than benchmark outcomes.

Architecture Differences

The AMD Radeon RX 7400 uses the Navi 33 chip on the RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is manufactured on a 6 nm process at TSMC. The NVIDIA N1 16SM uses the GB20B chip on the Blackwell 2.0 architecture, belongs to the Blackwell IGP (N1x) generation, and is built on a 5 nm process, also at TSMC.

The RX 7400 integrates 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The N1 16SM has a larger die at 382 mm², but its transistor count is recorded as unknown, so density cannot be calculated. The RX 7400 is a discrete dual-slot card with a 1x 6-pin power connector and a suggested 200 W power supply. The N1 16SM is an integrated graphics processor (IGP) with no power connectors and no suggested PSU rating.

Memory configurations differ sharply. The RX 7400 uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The N1's bandwidth is slightly lower despite the wider bus, because its memory clock is recorded at 1067 MHz (8.5 Gbps effective) versus 2250 MHz (18 Gbps effective) on the RX 7400.

The RX 7400 has 1792 shading units, 112 texture mapping units, and 64 ROPs. The N1 16SM has 2048 shading units, 128 TMUs, but only 24 ROPs. Ray tracing cores are 28 on the RX 7400 versus 16 on the N1. The N1 includes 64 tensor cores; the RX 7400 has none recorded.

Clock behavior also differs. The RX 7400 runs at a 1452 MHz base and 2300 MHz boost, with a 2200 MHz game clock. The N1 starts at 741 MHz base and boosts to 2346 MHz. The RX 7400 achieves a pixel rate of 147.2 GPixel/s and a texture rate of 257.6 GTexel/s. The N1 records 56.30 GPixel/s and 300.3 GTexel/s. The RX 7400's FP32 throughput is 16.49 TFLOPS, with FP16 at 32.97 TFLOPS (2:1). The N1's FP32 is 9.609 TFLOPS, and its FP16 is the same 9.609 TFLOPS (1:1).

The RX 7400 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A in the database. The RX 7400 connects over PCIe 4.0 x8, while the N1 uses PCIe 5.0 x16. Display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1 on the RX 7400, versus a single HDMI on the N1. The RX 7400 has no production status recorded; the N1 is listed as Active.

The Verdict

The recorded data supports a straightforward split. The AMD Radeon RX 7400 is the only one of the two with measured benchmark results, and its 2467 average score, while low (17th percentile), at least quantifies real performance. The NVIDIA N1 16SM has no benchmark scores, no API support entries, and no power figures, so its 50th percentile ranking cannot be verified against anything in the database.

For rendering throughput in raw FP32, the RX 7400 delivers 16.49 TFLOPS, which is 71% higher than the N1's 9.609 TFLOPS. Pixel fill is also far ahead on the RX 7400 at 147.2 GPixel/s versus 56.30 GPixel/s, a margin of roughly 161%. The RX 7400 also has more ROPs (64 versus 24) and more ray tracing cores (28 versus 16). The N1 counters with more shading units (2048 versus 1792), more TMUs (128 versus 112), a faster texture rate (300.3 GTexel/s versus 257.6 GTexel/s), and 64 tensor cores where the RX 7400 has none.

The N1 offers 128 GB of memory, which is 16 times the 8 GB on the RX 7400, but its bandwidth is slightly lower at 273.2 GB/s versus 288.0 GB/s. The RX 7400 has a much higher memory clock (18 Gbps effective versus 8.5 Gbps effective) and a narrower bus (128-bit versus 256-bit). The N1's memory advantage is capacity, not speed.

Based strictly on measured and recorded specifications, the RX 7400 is the stronger graphics part for traditional rendering workloads. The N1's tensor cores and large memory pool suggest a different role, but the database contains no benchmark data to confirm what that role delivers. Users needing verified graphics performance should rely on the RX 7400's recorded results.
