Architecture Differences

The two cards come from different architectural lineages. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename "Hotpink Bonefish." It belongs to the Console GPU (Valve) generation. The Intel Arc B570 uses the BMG-G21 chip based on Xe2-HPG architecture and belongs to the Battlemage (Arc 5) generation.

Manufacturing processes differ. AMD uses a 6 nm process from TSMC, while Intel uses a 5 nm process from TSMC. This contributes to different transistor densities: AMD packs 65.2 million transistors per square millimeter, and Intel achieves 72.1 million per square millimeter.

The compute layouts diverge substantially. The AMD card carries 1792 shading units, 112 texture mapping units, 64 raster operation units, and 28 ray tracing cores. The Intel card carries 2304 shading units, 144 texture mapping units, 80 raster operation units, and 18 ray tracing cores. Intel fields more shading units and texture units, but AMD fields more ray tracing cores.

Clock behavior also differs. AMD lists separate base, boost, and game clocks: 1720 MHz base, 2450 MHz boost, and 2250 MHz game clock. Intel lists a fixed base and boost clock, both at 2500 MHz, with no game clock specified. The AMD memory runs at 2250 MHz (18 Gbps effective), while Intel memory runs at 2375 MHz (19 Gbps effective).

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ slightly. AMD provides one HDMI 2.1a port and one DisplayPort 2.1 port. Intel provides one HDMI 2.1a port and three DisplayPort 2.1 ports.

Physical design separates the two clearly. The AMD Steam Machine GPU measures 156 mm in length, 152 mm in height, and 162 mm in width, with no slot width listed. The Intel Arc B570 measures 272 mm in length and 115 mm in height, with a dual-slot design. The AMD card draws 110 W TDP and requires no power connectors. The Intel card draws 150 W TDP and requires one 8-pin connector.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs between these two cards. The wins counter for each card is zero. However, the Intel Arc B570 has a full suite of recorded benchmark results, and the AMD Steam Machine GPU has none. This absence itself is informative: the database cannot verify the AMD card's real-world performance through standardized tests.

Intel's recorded scores show a spread across different workloads. In 3DMark Steel Nomad DX12, the Arc B570 scores 2649. In Geekbench OpenCL, it scores 83514, and in Geekbench Vulkan, it scores 96844. PassMark results include a G3D score of 14195 and a GPU compute score of 7281. DirectX 9 testing yields 164, DirectX 10 yields 65, DirectX 11 yields 118, and DirectX 12 yields 72. The G2D score is 661.

The average benchmark score of 20556 places the Arc B570 in the 65th percentile. Its nearest rivals show tight competition. The NVIDIA GeForce RTX 3070 Mobile averages 20534, a delta of 0.1 percent. The Intel Arc A750 averages 20582, a delta of negative 0.1 percent. The NVIDIA Quadro M4000M averages 20480, a delta of 0.4 percent. The AMD Radeon R9 M390X averages 20662, a delta of negative 0.5 percent. These deltas indicate the Arc B570 sits near a cluster of similarly scoring GPUs.

Without any benchmark data for the AMD Steam Machine GPU, the only quantitative performance comparisons available come from the specification sheet. The Intel card produces 200.0 GPixel/s pixel rate versus 156.8 GPixel/s for AMD. Texture rate favors Intel at 360.0 GTexel/s versus 274.4 GTexel/s. FP32 compute favors AMD at 17.56 TFLOPS versus 11.52 TFLOPS for Intel. FP16 compute favors Intel at 23.04 TFLOPS versus 17.56 TFLOPS for AMD. These figures suggest different workload strengths, but they are theoretical rates, not measured outcomes.

Where Each One Wins

The Intel Arc B570 demonstrates strengths in measured performance. Its average benchmark score of 20556 and 65th percentile ranking indicate verified, competitive performance against the recorded GPU population. Its nearest rivals, including the NVIDIA GeForce RTX 3070 Mobile and Intel Arc A750, score within a fraction of a percent, suggesting the Arc B570 occupies a well-established performance tier. The card's higher memory bandwidth, larger memory pool, and higher pixel and texture rates point to advantages in resolution-heavy and texture-heavy workloads. The dual-slot cooler and 150 W TDP suggest a conventional desktop card design with dedicated power delivery.

The AMD Steam Machine GPU shows strengths on paper in specific compute areas. Its FP32 throughput of 17.56 TFLOPS exceeds the Intel card's 11.52 TFLOPS by a significant margin. It also carries more ray tracing cores at 28 versus 18. The card's compact dimensions, lower 110 W TDP, and lack of power connectors indicate a design suited to constrained enclosures. Its 6 nm process and smaller die suggest a focus on power efficiency relative to the Intel card. The RDNA 3.0 architecture and console-oriented generation point toward a device built for a specific integrated platform rather than a general retail card.

The Intel card wins on memory capacity, bandwidth, pixel throughput, texture throughput, and FP16 compute. The AMD card wins on FP32 compute and ray tracing core count. The AMD card also wins on physical footprint and power draw, assuming the 110 W TDP reflects typical operating conditions.

The Verdict

The recorded data favors the Intel Arc B570 for general performance validation. It has a full benchmark suite, an average score of 20556, a 65th percentile ranking, and a clear set of nearest rivals with near-identical scores. Buyers or analysts seeking verified performance numbers have substantial evidence for the Intel card. Its 10 GB memory pool, 380.0 GB/s bandwidth, and higher pixel and texture rates support scenarios involving high resolutions, large textures, and heavy rasterization work. Its launch MSRP of 219 USD provides a fixed reference point, though the database offers no comparable figure for the AMD card.

The AMD Steam Machine GPU presents a more specialized case. Its 50th percentile ranking without any benchmark scores means its real-world position cannot be confirmed from the database. The specification sheet suggests a different design philosophy: lower power draw, no external power connector, compact dimensions, and higher FP32 throughput. These characteristics align with a console-style device where space and thermal limits shape the hardware. The 28 ray tracing cores and 17.56 TFLOPS FP32 rate indicate potential advantages in compute-oriented tasks, but the absence of recorded measurements leaves those gains unverified.

The release dates also matter. The Intel card released on 2025-01-15. The AMD card has a release date of 2026-06-28. The Intel card has an established market presence; the AMD card has a future release window. The Intel card lists a predecessor, Alchemist, while the AMD card lists none. The Intel card uses PCIe 4.0 x8, while the AMD card has no bus interface listed.

For anyone selecting between these two based strictly on the database, the Intel Arc B570 offers the only measured performance evidence. The AMD Steam Machine GPU offers a compelling specification sheet but no verified results. The choice depends on whether the user prioritizes documented performance or specific architectural traits such as FP32 throughput and ray tracing core count. The data does not support a claim that the AMD card outperforms the Intel card in any measured test, because no tests exist for it. The data does support the Intel card's position in a competitive performance cluster near the RTX 3070 Mobile and Arc A750. The AMD card remains an unknown quantity in practical terms, despite its distinctive design parameters.
