AMD Radeon 8040S vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8040S and NVIDIA H20 presents an unusual comparison challenge. The AMD Radeon 8040S has a full set of PassMark benchmark scores, while the NVIDIA H20 has no benchmark entries in the database at all. The H20 shows an average benchmark score of zero, with no individual test results recorded. This means the head-to-head comparison must be approached through the available performance data for the AMD part and the architectural characteristics of both products.

The AMD Radeon 8040S delivers a PassMark G3D score of 10,578. This places it in the 17th percentile among all GPUs tracked by the database. Its average benchmark score across all tests is 2,440. The nearest rivals in the database show how tightly clustered this performance level is. The NVIDIA GeForce 710M sits at an average score of 2,433, a delta of 0.3 percent relative to the 8040S. The Intel HD Graphics 610 records 2,425 average, a 0.6 percent delta. The NVIDIA GeForce GT 710M comes in at 2,422, a 0.7 percent delta. The AMD Radeon RX 7400 edges ahead with 2,467 average, a negative 1.1 percent delta from the 8040S perspective. These figures indicate the 8040S performs within a narrow band of older entry-level discrete and integrated solutions.

Breaking down the individual PassMark tests for the 8040S reveals its strengths and weaknesses. The DirectX 9 score of 134 is the highest among the DirectX tests, suggesting strong legacy DirectX 9 performance relative to its own DirectX 11 and 12 results. The DirectX 11 score of 80 and DirectX 10 score of 48 show a substantial drop-off. The DirectX 12 score of 47 is the lowest DirectX result. This pattern indicates the architecture handles older API workloads more efficiently than modern ones, which is notable for a GPU based on RDNA 3.5 architecture. The G2D score of 1,052 demonstrates strong 2D graphics capability. The GPU compute score of 5,138 shows compute workloads perform considerably better than the DirectX 11 and 12 scores might suggest.

The NVIDIA H20 has no benchmark scores to compare directly. Its percentile ranking of 50 versus the 8040S's 17th percentile suggests the H20 is positioned higher in the overall performance distribution, but without actual test scores in the database, a direct numerical comparison is impossible. The data shows the H20's average benchmark score as zero, which reflects missing measurements rather than a performance result.

Architecture Differences

The architectural gap between these two products is substantial. The AMD Radeon 8040S uses the Strix Halo chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. The die size is 308 mm². The transistor count is listed as unknown in the database. The NVIDIA H20 uses the GH100 chip based on Hopper architecture, manufactured on a 5 nm process at TSMC. The die size is 814 mm², more than two and a half times larger than the AMD part. The H20 contains 80,000 million transistors, with a transistor density of 98.3 million per square millimeter.

The 8040S belongs to the Navi Mobile (RX 8000M) generation, while the H20 belongs to the Server Hopper (Hxx) generation. The AMD part is classified as an integrated graphics processor with an IGP slot width, while the H20 is an SXM module designed for server deployment. The 8040S has no power connectors, consistent with its integrated nature, while the H20's power connectors are not specified in the database. The suggested power supply for the H20 is 900 W.

Clock speeds differ significantly. The 8040S has a base clock of 1,295 MHz and a boost clock of 2,800 MHz. The H20 operates at a base clock of 1,830 MHz and a boost clock of 1,980 MHz. The AMD part has a higher boost clock, but the NVIDIA part starts from a higher base. The memory clock for the H20 is listed as 1,313 MHz with 5.3 Gbps effective speed. The 8040S uses system shared memory, with the memory clock listed as system shared as well.

Memory configurations could hardly be more different. The 8040S uses system shared memory with shared type, shared bus width, and system dependent bandwidth. The H20 has 96 GB of HBM3 memory on a 6,144-bit bus, delivering 4.03 TB/s of bandwidth. This gives the H20 an enormous memory advantage in both capacity and bandwidth.

The compute unit configurations show a wide disparity. The 8040S has 1,024 shading units, 64 texture mapping units, and 32 raster output units. It also has 16 ray tracing cores. The H20 has 9,984 shading units, 312 texture mapping units, and only 24 raster output units. The H20 has 312 tensor cores, while the 8040S has no tensor core count listed. The ray tracing core count for the H20 is not specified.

Pixel and texture rates reflect these configurations. The 8040S achieves 89.60 GPixel/s and 179.2 GTexel/s. The H20 achieves 47.52 GPixel/s and 617.8 GTexel/s. The AMD part has nearly double the pixel throughput, while the NVIDIA part has more than triple the texture throughput. The FP32 performance tells a similar story: the 8040S delivers 5.734 TFLOPS, while the H20 delivers 39.54 TFLOPS. For FP16, the 8040S delivers 5.734 TFLOPS at a 1:1 ratio, while the H20 delivers 79.07 TFLOPS at a 2:1 ratio.

The API support differs completely. The 8040S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented design with no display outputs. The H20 has no display outputs at all, while the 8040S's display outputs are listed as portable device dependent.

The bus interface for both is PCIe 5.0 x16. The power consumption figures show the fundamental design difference: the 8040S has a TDP of 55 W, while the H20 has a TDP of 500 W. The release dates are close: the 8040S was released on January 5, 2025, and the H20 on January 31, 2024. The 8040S's predecessor is Polaris Mobile, while the H20's predecessor is Server Ada. The H20's successor is Server Blackwell, while the 8040S has no successor listed. Both are marked as active production status.

The Verdict

The data supports clear conclusions for different use cases. The AMD Radeon 8040S is a low-power integrated GPU with a 55 W TDP, designed for portable devices. Its benchmark scores show it performs in the range of older entry-level discrete GPUs, with its nearest rivals being the NVIDIA GeForce 710M, Intel HD Graphics 610, NVIDIA GeForce GT 710M, and AMD Radeon RX 7400. The 8040S's DirectX 9 score of 134 indicates strong legacy API performance, while its DirectX 12 score of 47 shows modern API workloads are less efficient. The GPU compute score of 5,138 demonstrates capable compute performance relative to its DirectX results.

The NVIDIA H20 is a server accelerator with a 500 W TDP, 96 GB of HBM3 memory, and no display outputs. Its architectural specifications point to a device designed for compute-intensive server workloads, with tensor cores and a very high FP16 throughput of 79.07 TFLOPS. The absence of benchmark scores in the database means its measured performance cannot be directly compared to the 8040S. However, the architectural data shows the H20 is built to handle memory-bandwidth-heavy and tensor-core-accelerated workloads at a scale far beyond what an integrated GPU could manage.

For gaming and general graphics workloads on portable devices, the 8040S is the only one of the two with display outputs and graphics API support. For server compute deployments requiring large memory capacity and tensor processing, the H20 is the clear choice based on its specifications. The data does not support a direct performance comparison, so the selection depends entirely on the workload and platform requirements.
