AMD Steam Machine GPU vs Intel Arc 140T Mobile Comparison

Head-to-Head Benchmarks

The database currently holds no head-to-head benchmark entries for the AMD Steam Machine GPU versus the Intel Arc 140T Mobile. With zero recorded wins for either side and no benchmark scores populated for either GPU, direct performance comparisons must be derived from the architectural and specification data available in the database rather than from measured test results.

The AMD Steam Machine GPU delivers 17.56 TFLOPS of FP32 compute, while the Intel Arc 140T Mobile produces 4.813 TFLOPS. This places the AMD part at roughly 3.6 times the raw floating-point throughput of the Intel solution. In FP16 workloads, the AMD GPU maintains 17.56 TFLOPS at a 1:1 ratio, whereas the Intel Arc 140T Mobile reaches 9.626 TFLOPS at a 2:1 ratio. The AMD advantage in FP32 is substantial, but the FP16 comparison narrows the gap considerably, with AMD still ahead by a factor of about 1.8.

Pixel throughput shows a similar pattern. The AMD Steam Machine GPU renders 156.8 GPixel/s, compared to 75.20 GPixel/s for the Intel Arc 140T Mobile. Texture fill rates stand at 274.4 GTexel/s for AMD versus 150.4 GTexel/s for Intel, meaning the AMD GPU processes roughly 82% more texture data per second. These figures indicate that the AMD part holds a decisive lead in every throughput category where both GPUs have recorded data.

Both GPUs occupy the 50th percentile against all GPUs in the database, and neither has an average benchmark score or a nearest rival list. The absence of measured results means the percentile ranking reflects the specification-based classification rather than actual performance testing. Users should interpret the architectural advantages as indicative of expected behavior, not verified outcomes.

Architecture Differences

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 chip is fabricated on a 6 nm process at TSMC and contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The Intel Arc 140T Mobile uses the Arrow Lake-H chip with Xe-LPG+ architecture, belongs to the Arc Graphics-M (Arrow Lake) generation, and is built on a 5 nm TSMC process. Intel has not disclosed transistor count, die size, or transistor density for this part.

The AMD GPU features 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. It also includes 28 ray tracing cores. The Intel Arc 140T Mobile has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Neither GPU uses dedicated tensor cores. Clock behavior differs sharply: the AMD part runs at a 1720 MHz base clock, 2250 MHz game clock, and 2450 MHz boost clock. Intel starts at a 300 MHz base clock and reaches 2350 MHz boost, with no game clock specified. The low base clock on Intel suggests aggressive power management, while the AMD GPU sustains much higher minimum operating frequencies.

Memory architecture separates the two parts fundamentally. The AMD Steam Machine GPU has 8 GB of GDDR6 memory on a 128-bit bus, with memory clocked at 2250 MHz (18 Gbps effective) and bandwidth of 288.0 GB/s. The Intel Arc 140T Mobile uses System Shared memory, meaning its capacity, type, bus width, and bandwidth are all system dependent. The database records its memory clock as System Shared, and bandwidth as System Dependent. This makes the Intel GPU reliant on the host platform's memory subsystem, while AMD carries dedicated VRAM with a fixed bandwidth figure.

Power consumption differs by a factor of roughly three. The AMD Steam Machine GPU has a TDP of 110 W and uses no external power connectors. The Intel Arc 140T Mobile has a TDP of 35 W and is an integrated graphics processor (IGP), drawing power through the host platform. The Intel GPU occupies no slot width and connects via the IGP bus interface, while the AMD GPU is a discrete card measuring 156 mm in length, 152 mm in height, and 162 mm in width. Display outputs differ as well: AMD provides 1x HDMI 2.1a and 1x DisplayPort 2.1, while Intel's display outputs are portable device dependent.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part uses GDDR6 memory with a 128-bit interface, while Intel's memory implementation is entirely system shared. The production status for both is Active. The AMD GPU has a release date of June 28, 2026, while the Intel Arc 140T Mobile was released January 12, 2025. Intel lists HD Graphics-M as the predecessor for the Arc 140T Mobile; AMD lists no predecessor. Neither GPU has a successor listed.

Where Each One Wins

The AMD Steam Machine GPU wins decisively in scenarios that demand raw throughput and sustained compute. Its 17.56 TFLOPS FP32 performance, 274.4 GTexel/s texture rate, and 156.8 GPixel/s pixel rate indicate strong suitability for rendering workloads that saturate shading units and texture pipelines. The dedicated 8 GB GDDR6 frame buffer with 288.0 GB/s bandwidth provides predictable memory performance independent of system configuration. The 28 ray tracing cores give the AMD part a hardware advantage for ray-traced effects, and the 2250 MHz game clock suggests consistent performance under sustained gaming loads. The 110 W TDP with no external power connectors implies the GPU receives power through the slot or a fixed console power delivery design, allowing it to maintain high clocks without user configuration.

The Intel Arc 140T Mobile wins in efficiency and system integration. Its 35 W TDP is roughly one third of the AMD GPU's power draw. The 300 MHz base clock and 2350 MHz boost clock indicate a wide dynamic range, allowing the GPU to idle at very low power and scale up when needed. The Xe-LPG+ architecture on Arrow Lake-H represents a newer process node at 5 nm, which contributes to its lower power envelope. The system shared memory design means the GPU has no dedicated VRAM allocation limits; it can draw on whatever system memory the host provides, which may be advantageous in configurations where unified memory access simplifies programming. The FP16 throughput of 9.626 TFLOPS at 2:1 ratio shows the Intel part can handle half-precision workloads with reasonable efficiency, even though it trails AMD in absolute FP16 output.

For portable devices, the Intel Arc 140T Mobile is the only viable option between the two, as its IGP form factor and portable device dependent display outputs target laptops and handhelds. The AMD Steam Machine GPU, with its discrete dimensions and fixed display outputs, belongs in a console-style chassis. Neither GPU has tensor cores, so AI acceleration workloads relying on dedicated tensor hardware are not supported by either part. The Intel GPU's 8 ray tracing cores provide entry-level RT capability, while AMD's 28 RT cores offer more parallel RT throughput.

The Verdict

The data indicates a clear performance hierarchy. The AMD Steam Machine GPU offers approximately 3.6 times the FP32 compute, 1.8 times the FP16 compute, 2.1 times the pixel rate, and 1.8 times the texture rate of the Intel Arc 140T Mobile. It also provides dedicated 8 GB GDDR6 memory with 288.0 GB/s bandwidth, compared to Intel's system dependent memory. Buyers or integrators seeking maximum graphics throughput for gaming or rendering should select the AMD Steam Machine GPU.

The Intel Arc 140T Mobile serves a different purpose entirely. Its 35 W TDP, IGP form factor, and system shared memory make it suitable for portable devices where power efficiency and integration matter more than absolute performance. The 5 nm process node and wide clock range from 300 MHz to 2350 MHz indicate a design optimized for variable workloads in battery-powered hardware. Users building or selecting a device where the GPU must share the platform's power and memory budget should choose the Intel part.

The absence of benchmark scores and head-to-head results in the database means these conclusions rest on specification analysis rather than measured performance. The 50th percentile ranking for both GPUs against all GPUs in the database suggests that neither part is at the extreme high end of the GPU spectrum. The AMD GPU's higher TDP and dedicated memory position it for stationary or docked use, while the Intel GPU's low power draw and system shared architecture position it for mobile integration. The release dates also matter: Intel shipped the Arc 140T Mobile in January 2025, while AMD's Steam Machine GPU is dated June 2026, indicating the AMD part is a later design.
