AMD Radeon 8040S vs AMD Steam Machine GPU Comparison

Head-to-Head Benchmarks

The recorded database contains a full set of benchmark scores for the AMD Radeon 8040S, while the AMD Steam Machine GPU has no benchmark entries at all. This makes a direct numerical comparison impossible, so the analysis must rely on the Radeon 8040S's absolute scores and its position relative to other known GPUs.

The Radeon 8040S delivers a Passmark G3D score of 10,578, which places it in the 17th percentile of all GPUs in the database. Its average benchmark score across all tests is 2,440. The strongest individual results come from the Passmark DirectX 11 test, where it scores 80, and the DirectX 9 test, where it scores 134. The compute-oriented Passmark GPU Compute test returns a score of 5,138, while the DirectX 10 and DirectX 12 tests produce scores of 48 and 47, respectively. The 2D graphics test, Passmark G2D, yields a score of 1,052.

Interpreting these numbers requires context. The nearest rivals for the Radeon 8040S, based on average benchmark score, are the NVIDIA GeForce 710M at 2,433, the Intel HD Graphics 610 at 2,425, the NVIDIA GeForce GT 710M at 2,422, and the AMD Radeon RX 7400 at 2,467. The Radeon 8040S sits 0.3% above the GeForce 710M, 0.6% above the Intel HD Graphics 610, and 0.7% above the GeForce GT 710M. Against the Radeon RX 7400, the 8040S trails by 1.1%. These delta percentages are small, indicating that the 8040S performs within a tight cluster of low-end GPUs. The 17th percentile ranking reinforces this: the 8040S is not a high-performance part by any stretch, and its benchmark profile is consistent with an integrated graphics solution.

The Steam Machine GPU, by contrast, has no recorded benchmark scores and no nearest rivals in the database. Its average benchmark score is listed as zero, which means the database contains no measurement data for this part. The head-to-head benchmark comparison is therefore empty: there are no wins for either side, and no numerical deltas to report. Any claim about which GPU is faster would require extrapolation from specifications, which is beyond the scope of the recorded data.

Architecture Differences

The two GPUs come from different AMD architectures and process nodes. The Radeon 8040S uses the Strix Halo chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. Its die size is 308 mm², and the transistor count is listed as unknown. The Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It is manufactured on a 6 nm process at TSMC, with a die size of 204 mm² and a transistor count of 13,300 million. The transistor density for the Steam Machine GPU is 65.2M per mm², while the 8040S has no recorded density figure.

The compute resources differ substantially. The Radeon 8040S has 1,024 shading units, 64 texture mapping units, 32 raster operation units, and 16 ray tracing cores. The Steam Machine GPU has 1,792 shading units, 112 texture mapping units, 64 raster operation units, and 28 ray tracing cores. This means the Steam Machine GPU carries 75% more shading units, 75% more TMUs, double the ROPs, and 75% more ray tracing cores. Neither GPU has tensor cores listed.

Memory architecture diverges sharply. The Radeon 8040S uses system-shared memory with a system-shared type, bus width, and bandwidth that are all dependent on the host platform. The Steam Machine GPU has 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. This is a fundamental difference: one relies on shared system memory, the other has a fixed, dedicated memory pool.

Clock speeds also differ. The Radeon 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz, with no game clock listed. The Steam Machine GPU has a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. The memory clock for the Steam Machine GPU is 2250 MHz with 18 Gbps effective data rate, while the 8040S's memory clock is system-dependent.

Where Each One Wins

Based on the recorded data, the Radeon 8040S wins in the only category where measurements exist: benchmark scores. It has a complete set of Passmark results, an average score of 2,440, and a 17th percentile ranking. Its nearest rival comparisons show it is competitive with low-end discrete and integrated GPUs, holding slight advantages over the GeForce 710M, HD Graphics 610, and GT 710M.

The Steam Machine GPU wins on raw specification counts. It has more shading units, more TMUs, more ROPs, and more ray tracing cores. It has a dedicated 8 GB GDDR6 memory pool with 288.0 GB/s bandwidth, whereas the 8040S shares system memory. Its FP32 throughput of 17.56 TFLOPS is more than triple the 8040S's 5.734 TFLOPS. Its pixel rate is 156.8 GPixel/s versus 89.60 GPixel/s, and its texture rate is 274.4 GTexel/s versus 179.2 GTexel/s.

The 8040S wins on power efficiency in a strict specification sense: it draws 55 W versus 110 W for the Steam Machine GPU. It also uses a smaller 4 nm process node, which typically indicates a more advanced manufacturing technology. The 8040S is an integrated part with no power connectors and a PCIe 5.0 x16 interface, while the Steam Machine GPU has no bus interface listed.

The Steam Machine GPU wins on physical form factor: its dimensions are recorded as 156 mm by 152 mm by 162 mm, making it a standalone card-like component. The 8040S has no dimensions, as it is an IGP. The Steam Machine GPU also has fixed display outputs, while the 8040S's outputs depend on the portable device it is integrated into.

The Verdict

The database contains no head-to-head benchmark results, so the verdict must be drawn from the available data: the 8040S has actual measured scores, and the Steam Machine GPU has none. Anyone seeking a GPU with a recorded performance profile in the database should choose the Radeon 8040S, as it provides a complete set of Passmark scores and a clear percentile ranking of 17th. Its average benchmark score of 2,440 places it in a narrow band around the GeForce 710M, HD Graphics 610, GT 710M, and Radeon RX 7400, with deltas ranging from 0.3% to 1.1%. This is a low-end part, but it is a measured one.

The Steam Machine GPU, despite having no benchmarks, presents a specification profile that suggests a substantially higher performance ceiling. It has 1,792 shading units, 28 ray tracing cores, 17.56 TFLOPS of FP32 throughput, and 8 GB of dedicated GDDR6 memory with 288.0 GB/s bandwidth. Its 50th percentile ranking, though unsupported by any recorded test scores, indicates the database positions it in the middle of the GPU distribution. The 8040S, by contrast, sits at the 17th percentile.

The practical choice depends on whether the user trusts measured data or specification extrapolation. The recorded data favors the 8040S for anyone who requires verified benchmark results. The specification data favors the Steam Machine GPU for anyone who prioritizes raw compute resources, dedicated memory, and higher throughput figures. The 8040S is the only part with a proven performance record in the database; the Steam Machine GPU is a specification sheet with no test results behind it.
