The Verdict

The data shows two products with entirely different intended roles. The AMD Radeon 8040S is an integrated GPU, classified as an IGP with no power connectors and a slot width of IGP, designed for portable devices. Its benchmark results place it at the 17th percentile among all GPUs, with an average score of 2440. Its nearest rivals include the NVIDIA GeForce 710M with an average score of 2433 and a delta of 0.3, the Intel HD Graphics 610 with a score of 2425 and a delta of 0.6, and the NVIDIA GeForce GT 710M with a score of 2422 and a delta of 0.7. The AMD Radeon RX 7400 sits slightly ahead with a score of 2467 and a delta of -1.1 relative to the 8040S. This indicates the 8040S performs in the low-end mobile segment, competing with older entry-level discrete parts and basic integrated graphics.

The NVIDIA GeForce RTX 5090 SE is a dual-slot, 500 W discrete card with a 16-pin power connector and a suggested power supply of 900 W. It has no benchmark scores recorded in the database, and its average benchmark score is listed as 0. Its percentile rank is 50, but this value is not supported by any actual test results in the available data. The lack of recorded benchmarks means no direct performance comparison can be made from measured results.

For users selecting between these two, the choice is dictated by platform and workload. The 8040S suits ultraportable systems where low power consumption and integrated graphics are required. The RTX 5090 SE targets high-end desktop configurations with dedicated power delivery and a large memory pool. The RTX 5090 SE, with 24 GB of GDDR7 memory and 14080 shading units, is clearly the more capable part on paper, but the database contains no measured benchmark data to confirm its real-world standing. The 8040S has measurable results, but they are modest, placing it near the bottom of the performance distribution.

Head-to-Head Benchmarks

The database does not contain any head-to-head benchmark entries for these two GPUs. The wins count for each is zero. The only benchmark data available belongs to the AMD Radeon 8040S, which has seven recorded PassMark tests. The NVIDIA GeForce RTX 5090 SE has an empty benchmark array.

For the 8040S, the recorded scores are as follows: PassMark DirectX 10 at 48, PassMark DirectX 11 at 80, PassMark DirectX 12 at 47, PassMark DirectX 9 at 134, PassMark G2D at 1052, PassMark G3D at 10578, and PassMark GPU Compute at 5138. These numbers indicate that the DirectX 9 test produces the highest score among the DirectX variants, while DirectX 12 and DirectX 10 are close to each other. The G3D score of 10578 far exceeds the compute score of 5138, suggesting the 8040S handles general 3D raster workloads better than compute tasks in these specific tests.

The RTX 5090 SE has no comparable scores. Without any benchmark results, a quantitative head-to-head comparison is impossible. The database lists no tests, no average score, and no nearest rivals for the RTX 5090 SE. Any assertion about its performance relative to the 8040S would rely on specs, not measurements.

The nearest rivals for the 8040S provide context for its standing. The NVIDIA GeForce 710M is 0.3% ahead, the Intel HD Graphics 610 is 0.6% ahead, and the NVIDIA GeForce GT 710M is 0.7% ahead. The AMD Radeon RX 7400 is 1.1% behind the 8040S, meaning the 8040S actually leads that part by a small margin. These deltas are all within a couple of points, indicating that the 8040S performs in a tight cluster with these older and entry-level parts.

The RTX 5090 SE has 14080 shading units, 440 TMUs, 160 ROPs, 110 ray tracing cores, and 440 tensor cores. The RTX 5090 SE has 13 times more shading units, nearly 7 times more TMUs, and 5 times more ROPs.

Pixel and texture rates reflect these differences. The 8040S has a pixel rate of 89.60 GPixel/s and a texture rate of 179.2 GTexel/s. The RTX 5090 SE has a pixel rate of 380.3 GPixel/s and a texture rate of 1,045.9 GTexel/s. The RTX 5090 SE is 4.2 times faster in pixel rate and 5.8 times faster in texture rate.

Floating point performance also differs greatly. The 8040S achieves 5.734 TFLOPS in both FP32 and FP16 (1:1). The RTX 5090 SE achieves 66.94 TFLOPS in both FP32 and FP16 (1:1). This is an 11.7 times difference in raw FP32 throughput.

Power requirements are polar opposites. The 8040S has a TDP of 55 W, no power connectors, and an IGP slot width. The RTX 5090 SE has a TDP of 500 W, requires a 16-pin power connector, has a suggested PSU of 900 W, and occupies a dual-slot form factor. The RTX 5090 SE has physical dimensions of 267 mm length, 111 mm height, and 40 mm width. The 8040S has no recorded dimensions.

Display outputs differ as well. The 8040S has outputs listed as portable device dependent. The RTX 5090 SE has 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Bus interfaces are the same, both using PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The release dates differ: the 8040S was released on 2025-01-05, while the RTX 5090 SE was released on 2025-12-31. Both are marked as active in 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 GeForce RTX 5090 SE uses the Blackwell 2.0 architecture with the GB202 chip, part of the GeForce 50-series and GeForce 50 generation. Its predecessor is the GeForce 40 series, and its successor is listed as GeForce 60.

The 8040S has no tensor cores listed, while the RTX 5090 SE has 440 tensor cores. This is a key architectural difference, as tensor cores are used for AI and deep learning workloads. The 8040S has 16 ray tracing cores, whereas the RTX 5090 SE has 110, a difference of 94 cores.

Shader organization differs by design. The 8040S uses 1024 shading units, 64 TMUs, and 32 ROPs, a ratio typical of an integrated solution. The RTX 5090 SE uses 14080 shading units, 440 TMUs, and 160 ROPs, a much wider configuration suited for high-resolution rendering.

The transistor count and die size reflect the architectural scale. The RTX 5090 SE packs 92,200 million transistors into a 750 mm² die, using a 5 nm process. The 8040S uses a 308 mm² die on a 4 nm process, but its transistor count is unknown. The smaller die and lower power envelope indicate a design focused on efficiency for mobile integration.

Memory architecture is fundamentally different. The 8040S relies on system shared memory, meaning its performance is tied to the host system's memory speed and capacity. The RTX 5090 SE has dedicated 24 GB GDDR7 memory with a 384-bit interface, providing 1.34 TB/s of bandwidth. This dedicated memory pool avoids contention with the CPU and system tasks.

The API support is identical across both parts. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means software compatibility is not a differentiator, though the underlying hardware capabilities differ substantially.

The release timeline shows the 8040S launched earlier in the year, while the RTX 5090 SE is dated at the end of 2025. Both are active products, but the 8040S is positioned as a mobile integrated solution, while the RTX 5090 SE is a high-end desktop discrete card.

The power delivery systems are unique to each design. The 8040S draws power from the host system with no dedicated connectors, fitting its IGP classification. The RTX 5090 SE requires a single 16-pin connector and a suggested 900 W power supply, indicating a power draw that necessitates a robust desktop PSU.

In summary, the architectural gap is enormous. The RTX 5090 SE has more shading units, more tensor cores, more ray tracing cores, dedicated high-bandwidth memory, and a much higher power ceiling. The 8040S is a low-power integrated part with modest compute resources and shared memory. The recorded benchmark data only covers the 8040S, and its scores place it in the lowest percentile range. The RTX 5090 SE has no measured results in the database, so its performance cannot be verified from available data, but its specifications indicate a part in a completely different performance class.
