AMD Steam Machine GPU vs Intel Iris Xe Graphics 80EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark results between the AMD Steam Machine GPU and the Intel Iris Xe Graphics 80EU Mobile. Both entries have empty benchmark arrays, zero average benchmark scores, and zero wins in the head-to-head comparison. The percentileVsAllGpus field places both at the 50th percentile, indicating they occupy the same relative position in the database’s overall GPU distribution, though this does not reflect any direct performance comparison.

Without measured scores, the analysis must rely on the architectural and specification data provided. The AMD Steam Machine GPU delivers a peak FP32 throughput of 17.56 TFLOPS, while the Intel Iris Xe Graphics 80EU Mobile reaches 1.856 TFLOPS in FP32. The AMD part is approximately 9.46 times higher in raw FP32 compute, a difference that dwarfs any other gap between the two. The Intel part’s FP16 throughput is 3.712 TFLOPS, which is double its FP32 rate due to a 2:1 ratio, whereas the AMD part lists FP16 at 17.56 TFLOPS with a 1:1 ratio, meaning no FP16 acceleration advantage.

The pixel rate for the AMD Steam Machine GPU is 156.8 GPixel/s, compared to 29.00 GPixel/s for the Intel Iris Xe Graphics 80EU Mobile, a 5.4 times difference. The texture rate shows 274.4 GTexel/s for AMD versus 58.00 GTexel/s for Intel, a 4.7 times gap. These figures indicate that the AMD part has substantially higher fillrate capabilities, which typically translates to better performance in resolution-heavy workloads and texture-bound scenarios.

Memory bandwidth further separates the two. The AMD Steam Machine GPU has 288.0 GB/s of dedicated GDDR6 bandwidth across a 128-bit bus, while the Intel Iris Xe Graphics 80EU Mobile relies on System Shared memory with bandwidth listed as System Dependent. The AMD part’s dedicated memory avoids contention with the CPU and provides predictable bandwidth, whereas the Intel part’s performance scales with system memory configuration, which is not quantified in the database.

The shading unit count is 1792 for AMD versus 640 for Intel, a 2.8 times difference. Texture mapping units are 112 versus 40, and raster output units are 64 versus 20. The AMD part also includes 28 ray tracing cores, while the Intel part lists no ray tracing cores. These structural differences align with the compute and fillrate gaps, reinforcing that the AMD Steam Machine GPU is designed for a much higher performance tier.

The Verdict

The data indicates that the AMD Steam Machine GPU is the higher-performance part in every measurable specification category. Its FP32 compute is 17.56 TFLOPS versus 1.856 TFLOPS for the Intel Iris Xe Graphics 80EU Mobile, its pixel rate is 156.8 GPixel/s versus 29.00 GPixel/s, and its texture rate is 274.4 GTexel/s versus 58.00 GTexel/s. The AMD part also has more than double the shading units, nearly three times the TMUs, and more than three times the ROPs. The Intel part’s only advantage is its FP16 compute ratio, which doubles its FP32 throughput, but even that doubled figure (3.712 TFLOPS) remains far below the AMD part’s FP16 rate of 17.56 TFLOPS.

The power envelope also differs significantly: the AMD Steam Machine GPU has a TDP of 110 W, while the Intel Iris Xe Graphics 80EU Mobile has a TDP of 15 W. This 95 W difference explains the performance gap, as the AMD part consumes substantially more power to deliver its higher throughput. The Intel part is an integrated graphics processor (IGP) with a Ring Bus interface, while the AMD part is a discrete console GPU with no power connectors listed, indicating it draws power through the system board.

The Intel Iris Xe Graphics 80EU Mobile does have a successor listed (Arc Graphics-M), while the AMD Steam Machine GPU has no successor. The AMD part is newer, with a release date of 2026-06-28, versus 2023-01-03 for the Intel part. None of the benchmark results exist to directly compare real-world performance, so the verdict rests entirely on the specification sheet, which uniformly favors the AMD part.

Where Each One Wins

The AMD Steam Machine GPU wins in every category where a direct comparison is possible: raw compute, pixel throughput, texture throughput, memory bandwidth, and feature set. It has dedicated 8 GB GDDR6 memory, a 128-bit bus, and 288.0 GB/s bandwidth, which suits high-resolution rendering and large texture datasets. Its 28 ray tracing cores support hardware-accelerated ray tracing, which the Intel part lacks entirely. The AMD part also supports DirectX 12 Ultimate (12_2), while the Intel part supports DirectX 12 (12_1), a feature-level difference that affects advanced rendering effects.

The Intel Iris Xe Graphics 80EU Mobile wins in power efficiency and system integration. Its 15 W TDP is 95 W lower than the AMD part’s 110 W, making it suitable for thin-and-light portable devices where thermal and power budgets are constrained. It uses System Shared memory, which eliminates the need for dedicated VRAM and reduces component count. Its FP16 throughput is double its FP32 rate, which can benefit workloads that use half-precision arithmetic, though the absolute FP16 performance is still far below the AMD part.

The Intel part also has a longer production history, with a release date in early 2023, and it has a clearly defined successor in Arc Graphics-M, indicating an ongoing product line. The AMD Steam Machine GPU is a newer, single-purpose console part with no successor, suggesting it is a fixed design for a specific Valve product. The AMD part’s dimensions are 156 mm by 152 mm by 162 mm, while the Intel part has no listed dimensions, as it is an IGP integrated into a processor package.
