AMD Radeon RX 7400 vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon RX 7400 includes eight benchmark entries, while the NVIDIA N1X 48SM has no benchmark scores listed in the database. This creates an asymmetric comparison where the AMD part can be evaluated against its nearest rivals, but the NVIDIA part cannot be directly scored in the same tests. The AMD Radeon RX 7400 delivers an average benchmark score of 2467 across all recorded tests, placing it at the 17th percentile among all GPUs in the database. The NVIDIA N1X 48SM holds a 50th percentile ranking, but with an average benchmark score of zero and no individual test results, the percentile figure reflects its position in the database hierarchy rather than measured performance.

Looking at the AMD Radeon RX 7400's specific benchmark results, the strongest showing comes in the Passmark G3D test with a score of 11897. The Passmark G2D test returns 1209, while the DirectX 9 test produces 176. DirectX 11 scores 97, DirectX 10 scores 59, and DirectX 12 scores 44. The GPU compute test records 5152, and the 3DMark Steel Nomad DX12 test yields 1103.

The nearest rivals for the AMD Radeon RX 7400, based on average benchmark score, are the AMD Radeon 8040S at 2440, the NVIDIA GeForce 710M at 2433, the Intel HD Graphics 610 at 2425, and the NVIDIA GeForce GT 710M at 2422. The RX 7400 sits 1.1% above the Radeon 8040S, 1.4% above the GeForce 710M, 1.8% above the Intel HD Graphics 610, and 1.9% above the GeForce GT 710M. These delta percentages are small, indicating that the RX 7400 occupies a performance tier only marginally ahead of these older or lower-end parts. The data shows a narrow margin of victory, not a decisive lead.

Because the NVIDIA N1X 48SM has no benchmark results, no head-to-head wins can be assigned to either product. The database records zero wins for each side. The comparison therefore rests on architectural specifications, feature sets, and the AMD part's measured standing among its own rivals.

Architecture Differences

The AMD Radeon 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 within the Radeon RX 7000 series. The process node is 6 nm at TSMC, with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter.

The NVIDIA N1X 48SM uses the GB20B chip built on Blackwell 2.0 architecture, with no codename listed. It belongs to the Blackwell IGP generation under the N1x family. The process node is 5 nm at TSMC, with a die size of 382 mm². Transistor count is listed as unknown, and transistor density is not recorded. The NVIDIA part uses a smaller process node, 5 nm versus 6 nm, but the die is significantly larger at 382 mm² versus 204 mm². Without transistor counts for the NVIDIA chip, density comparisons cannot be made from the data.

The AMD Radeon RX 7400 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 48SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This means the AMD part exposes a full modern graphics API stack, while the NVIDIA part's API support is not specified in the database.

Display outputs differ substantially. The AMD Radeon RX 7400 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. The NVIDIA N1X 48SM provides only 1x HDMI with no version specified. The AMD card is a dual-slot discrete solution with a 1x 6-pin power connector and a suggested power supply of 200 W. The NVIDIA part is an integrated graphics processor (IGP) with no power connectors and no suggested PSU listed.

The bus interface also differs: the AMD Radeon RX 7400 uses PCIe 4.0 x8, while the NVIDIA N1X 48SM uses PCIe 5.0 x16. The NVIDIA part has a wider and newer bus interface, but as an IGP, it does not occupy a slot in the conventional sense.

Where Each One Wins

The AMD Radeon RX 7400 wins in measured performance because it has eight recorded benchmark scores, and the NVIDIA N1X 48SM has none. The RX 7400's average benchmark score of 2467 places it above its nearest rivals, all of which are older or lower-tier parts. The margin is narrow, between 1.1% and 1.9%, but it is a consistent lead across the four nearest rivals in the database.

The RX 7400 also wins on API support, offering DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the NVIDIA part lists N/A for all three. This makes the AMD part usable in modern applications that require these APIs, while the NVIDIA part's compatibility is undocumented.

The RX 7400 wins on display output flexibility, with three DisplayPort 2.1 outputs and one HDMI 2.1a port. The NVIDIA N1X 48SM has only a single HDMI output. For multi-monitor setups or high-refresh-rate displays, the AMD part provides more options.

The NVIDIA N1X 48SM wins on raw compute specifications. Its FP32 throughput is 28.83 TFLOPS, compared to 16.49 TFLOPS for the RX 7400. That is a 74.8% higher FP32 figure. The NVIDIA part also has 6144 shading units versus 1792, 384 texture mapping units versus 112, and 192 tensor cores versus none on the AMD side. The NVIDIA part has 48 ray tracing cores versus 28 on the AMD part.

The NVIDIA N1X 48SM wins on memory capacity. It has 128 GB of LPDDR5X on a 256-bit bus, while the RX 7400 has 8 GB of GDDR6 on a 128-bit bus. However, the AMD part has slightly higher memory bandwidth at 288.0 GB/s versus 273.2 GB/s for the NVIDIA part. The NVIDIA memory clock is 1067 MHz with 8.5 Gbps effective, while the AMD memory clock is 2250 MHz with 18 Gbps effective. The AMD memory runs at a higher effective speed, but the NVIDIA part has 16 times the capacity.

The NVIDIA N1X 48SM wins on texture rate, delivering 900.9 GTexel/s versus 257.6 GTexel/s for the AMD part. The NVIDIA part also has a higher boost clock at 2346 MHz versus 2300 MHz for the AMD part, though the AMD base clock is higher at 1452 MHz versus 741 MHz.

The NVIDIA part wins on pixel rate? No, the AMD part wins there. The RX 7400 has a pixel rate of 147.2 GPixel/s, while the NVIDIA N1X 48SM has 112.6 GPixel/s. The AMD part also has more ROPs at 64 versus 48.

The AMD part wins on FP16 throughput relative to its FP32, listing 32.97 TFLOPS at a 2:1 ratio, while the NVIDIA part lists 28.83 TFLOPS at a 1:1 ratio. For workloads that use FP16, the AMD part can process more half-precision operations per second than the NVIDIA part, despite having lower FP32 throughput.

The NVIDIA N1X 48SM wins on production status, listed as Active, while the AMD part has no production status recorded. The NVIDIA part also has a later release date of May 31, 2026, compared to August 7, 2025 for the AMD part.
