AMD Steam Machine GPU vs Intel UHD Graphics 770 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the AMD Steam Machine GPU and the Intel UHD Graphics 770 Mobile. Both entries in the database show zero benchmark scores, zero wins for either side, and no nearest rival comparisons. This absence of measured performance data means a comparative analysis must rely on the architectural specifications and raw compute capabilities recorded for each part.

The AMD Steam Machine GPU delivers 17.56 TFLOPS of FP32 compute, while the Intel UHD Graphics 770 Mobile provides 819.2 GFLOPS. This represents a 21.4x difference in raw floating-point throughput, a gap that would translate into substantially higher frame rates in any GPU-bound workload. The pixel throughput figures reinforce this: the AMD part reaches 156.8 GPixel/s versus 12.80 GPixel/s for Intel, an approximate 12.3x advantage. Texture rate shows a similar pattern, with AMD at 274.4 GTexel/s compared to Intel's 25.60 GTexel/s, an 10.7x margin.

Since the database records no actual benchmark runs, these specification-derived deltas stand as the only quantitative comparison available. The percentile fields for both GPUs are identical at 50, which places both in the middle of the database distribution, but this percentile is computed from an empty benchmark set and should not be interpreted as evidence of comparable real-world performance.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Console GPU (Valve) generation. It is fabricated on a 6 nm process at TSMC, integrating 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter.

The Intel UHD Graphics 770 Mobile uses the Raptor Lake chip with Generation 12.2 architecture, classified as HD Graphics-M (Raptor Lake). It is built on Intel's 10 nm process. The database records no transistor count, die size, or density for the Intel part, which reflects its integrated nature. The Intel GPU operates as an IGP with a Ring Bus interface, whereas the AMD part uses no bus interface entry and relies on a discrete design with power connectors listed as none.

Clock behavior differs sharply. The AMD GPU runs at a 1720 MHz base clock, a 2450 MHz boost clock, and a 2250 MHz game clock. The Intel part has a 300 MHz base and 1600 MHz boost, with no game clock recorded. Memory configurations are entirely different: AMD uses 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth, while Intel uses system shared memory with system dependent bandwidth, a system shared type, and system shared bus width.

Shading resources diverge dramatically. The AMD GPU contains 1792 shading units, 112 texture mapping units, 64 raster operation pipelines, and 28 ray tracing cores. Intel provides 256 shading units, 16 TMUs, and 8 ROPs, with no ray tracing cores listed. API support also differs: AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Intel lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_2 versus 12_1 distinction indicates AMD supports the full hardware ray tracing and mesh shader feature set, while Intel does not reach that tier.

Power consumption shows a large gap. The AMD Steam Machine GPU has a TDP of 110 W, while the Intel UHD Graphics 770 Mobile draws 15 W. The AMD part measures 156 mm in length, 152 mm in height, and 162 mm in width, with display outputs of 1x HDMI 2.1a and 1x DisplayPort 2.1. Intel lists no dimensions and describes display outputs as portable device dependent.

Where Each One Wins

Based on the recorded specifications, the AMD Steam Machine GPU holds the advantage in every compute-heavy category. Its 17.56 TFLOPS FP32 throughput, 28 ray tracing cores, and DirectX 12 Ultimate support position it for demanding 3D rendering, ray-traced effects, and high-resolution gaming. The 288.0 GB/s dedicated memory bandwidth eliminates the bottleneck of shared system memory, and the 8 GB GDDR6 capacity allows larger texture sets and geometry buffers than an IGP can access.

The Intel UHD Graphics 770 Mobile wins in power efficiency and integration. Its 15 W TDP is a fraction of the AMD part's 110 W, making it suitable for thin-and-light portable devices where thermal and battery constraints dominate. Its Ring Bus interface and system shared memory model require no dedicated video memory, reducing system cost and complexity. The Intel part also has a production status of Active and carries a successor, Arc Graphics-M, while the AMD part has no successor listed.

The FP16 figures provide another differentiator. AMD lists FP16 at 17.56 TFLOPS with a 1:1 ratio, meaning FP16 performance matches FP32. Intel lists FP16 at 1.638 TFLOPS with a 2:1 ratio, meaning FP16 is double FP32 throughput. For workloads that use FP16 math, such as certain machine learning inference tasks, Intel's ratio offers a relative efficiency boost, but the absolute performance remains far below AMD's numbers.

The Verdict

The database shows two GPUs designed for opposite ends of the performance spectrum. The AMD Steam Machine GPU, with its discrete memory, ray tracing hardware, and 110 W power envelope, targets sustained high-throughput graphics workloads. Its 156.8 GPixel/s pixel rate and 274.4 GTexel/s texture rate indicate it can feed high-resolution displays and complex shader programs without stalling.

The Intel UHD Graphics 770 Mobile, with 15 W TDP and system shared memory, serves as a basic display controller and light 3D accelerator for portable systems. Its 12.80 GPixel/s and 25.60 GTexel/s rates suffice for desktop composition, video playback, and undemanding 2D or casual 3D applications, but they fall orders of magnitude short of the AMD part.

Any user selecting between these two should base their choice on the target platform. A dedicated Steam Machine console form factor requires the AMD GPU's compute resources and memory bandwidth. An ultraportable laptop or mini PC with modest graphics needs can rely on the Intel IGP. The data provides no middle ground: the AMD part is a discrete high-performance component, the Intel part is an integrated low-power solution, and their specifications confirm no overlap in intended use cases.
