Analysis: AMD Radeon 8040S vs NVIDIA N1X 40SM

Where Each One Wins

The AMD Radeon 8040S and the NVIDIA N1X 40SM occupy different positions in the recorded database. The AMD part has a complete set of benchmark entries, while the NVIDIA part currently has no recorded benchmark scores. This makes a direct comparison of measured performance impossible at this time.

The AMD Radeon 8040S shows a PassMark G3D score of 10578. Its PassMark GPU compute score is 5138. In the older DirectX tests, it scores 134 in DirectX 9, 80 in DirectX 11, 48 in DirectX 10, and 47 in DirectX 12. The G2D score is 1052. The average benchmark score for the AMD part is 2440.

The NVIDIA N1X 40SM has no benchmark entries in the database. Its average benchmark score is recorded as 0, and its nearest rivals list is empty. The percentile versus all GPUs is 50, compared to 17 for the AMD part. However, without measured scores, that percentile cannot be verified against actual test data.

The AMD Radeon 8040S is the only one of the two with recorded wins. It wins every benchmark category by default, because the NVIDIA part has no measured results. The database records 0 wins for the NVIDIA N1X 40SM and 0 wins for the AMD Radeon 8040S in head-to-head comparisons, which reflects the absence of direct comparative benchmarks.

A: The AMD Radeon 8040S boosts to 2800 MHz from a base of 1295 MHz. The NVIDIA N1X 40SM boosts to 2346 MHz from a base of 741 MHz.

Q: Which GPU has a higher pixel rate?

A: The NVIDIA N1X 40SM has a pixel rate of 93.84 GPixel/s. The AMD Radeon 8040S has a pixel rate of 89.60 GPixel/s. The NVIDIA part is ahead by 4.24 GPixel/s.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The AMD Radeon 8040S has its own benchmark results, but the NVIDIA N1X 40SM has none. Direct comparison of measured performance is therefore not possible from the recorded data.

The AMD part delivers 5.734 TFLOPS of FP32 performance and 5.734 TFLOPS of FP16 performance, with a 1:1 ratio. Its texture rate is 179.2 GTexel/s and pixel rate is 89.60 GPixel/s. These figures are entirely from the AMD part's own benchmark records.

The NVIDIA N1X 40SM shows 24.02 TFLOPS of FP32 and 24.02 TFLOPS of FP16, also at a 1:1 ratio. Its texture rate is 750.7 GTexel/s and pixel rate is 93.84 GPixel/s. These are specification values, not measured benchmark scores.

In the absence of direct test data, the specification comparison indicates that the NVIDIA part has substantially higher raw compute limits. The FP32 figure for the NVIDIA part is 24.02 TFLOPS, which is roughly 4.2 times the 5.734 TFLOPS of the AMD part. The texture rate difference is even larger: 750.7 GTexel/s versus 179.2 GTexel/s.

However, the AMD part has the only actual benchmark results. Its nearest rivals in the database are the NVIDIA GeForce 710M with an average score of 2433 and a delta of 0.3 percent, the Intel HD Graphics 610 with an average score of 2425 and a delta of 0.6 percent, and the NVIDIA GeForce GT 710M with an average score of 2422 and a delta of 0.7 percent. The AMD Radeon RX 7400 sits at 2467 with a delta of -1.1 percent. These deltas are small, placing the AMD Radeon 8040S in a narrow performance band among these rivals.

The percentile data shows the AMD part at 17 percent versus all GPUs, while the NVIDIA part is listed at 50 percent. Without benchmark scores for the NVIDIA part, that percentile cannot be cross-checked against measured results.

Specification Differences

The two GPUs differ across nearly every recorded specification field.

The AMD Radeon 8040S uses a 4 nm process node at TSMC. The NVIDIA N1X 40SM uses a 5 nm process node at TSMC. Die size differs: the AMD part is 308 mm², while the NVIDIA part is 382 mm². Transistor counts are unknown for both.

Clock speeds differ significantly. The AMD part has a base clock of 1295 MHz and a boost clock of 2800 MHz. The NVIDIA part has a base clock of 741 MHz and a boost clock of 2346 MHz. The AMD part runs at higher clock speeds, but the NVIDIA part has far more execution units.

Memory configuration is a major difference. The AMD Radeon 8040S uses system shared memory with system dependent bandwidth. The NVIDIA N1X 40SM has 128 GB of LPDDR5X memory, a 256 bit bus, and 273.2 GB/s bandwidth. Its memory clock is 1067 MHz with 8.5 Gbps effective.

Compute unit counts are recorded under different names. The AMD part has 1024 shading units, 64 TMUs, 32 ROPs, and 16 RT cores. The NVIDIA part has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The NVIDIA part does not list tensor cores for the AMD part.

Pixel rate is close: 89.60 GPixel/s for AMD versus 93.84 GPixel/s for NVIDIA. Texture rate is not close: 179.2 GTexel/s for AMD versus 750.7 GTexel/s for NVIDIA. FP32 and FP16 both show 5.734 TFLOPS for AMD and 24.02 TFLOPS for NVIDIA, with 1:1 ratios for both.

The AMD part has a TDP of 55 W. The NVIDIA part has an unknown TDP. Both use IGP slot width and have no power connectors. Both use PCIe 5.0 x16 bus interface.

Display outputs differ. The AMD part is listed as portable device dependent. The NVIDIA part is listed as 1x HDMI.

API support differs. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan.

Release dates differ. The AMD part was released on 2025-01-05. The NVIDIA part is dated 2026-05-31. Both have active production status.

Architecture Differences

The AMD Radeon 8040S is built on the RDNA 3.5 architecture and uses the Strix Halo chip. It belongs to the Navi Mobile (RX 8000M) generation. Its predecessor is listed as Polaris Mobile.

The NVIDIA N1X 40SM is built on the Blackwell 2.0 architecture and uses the GB20B chip. It belongs to the Blackwell IGP (N1x) generation. No predecessor is listed for the NVIDIA part.

The process nodes reflect a generational difference: 4 nm for the AMD part versus 5 nm for the NVIDIA part, both at TSMC. The die size is larger for the NVIDIA part at 382 mm², compared to 308 mm² for the AMD part.

The compute architecture differs in scale. The AMD part has 16 RT cores and no tensor cores listed. The NVIDIA part has 40 RT cores and 160 tensor cores. The shading unit count of 5120 for the NVIDIA part is five times the 1024 of the AMD part. The TMU count of 320 for NVIDIA is five times the 64 of AMD. The ROP count of 40 for NVIDIA is 8 higher than the 32 of AMD.

Memory architecture differs fundamentally. The AMD part relies on system shared memory, making bandwidth system dependent. The NVIDIA part has dedicated 128 GB of LPDDR5X with a 256 bit bus and 273.2 GB/s bandwidth.

The API profiles differ. The AMD part has a full DirectX 12 Ultimate (12_2) implementation, OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for all three API categories in the database. This indicates that the recorded API support for the NVIDIA part is not yet established in the database.

The AMD part has a TDP of 55 W, while the NVIDIA part has an unknown TDP. Both are IGP-class parts with no power connectors.

The release timeline places the AMD part in early 2025 and the NVIDIA part in mid-2026. Both are marked as active in production.

The benchmark records show a clear asymmetry. The AMD Radeon 8040S has a full set of PassMark scores and a percentile of 17. The NVIDIA N1X 40SM has no benchmark entries, an average score of 0, and a percentile of 50. The database treats the NVIDIA part as having higher percentile standing, but it currently lacks the measured results to support direct comparison with the AMD part.
