AMD Steam Machine GPU vs Intel Arc Graphics 48EU Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either the AMD Steam Machine GPU or the Intel Arc Graphics 48EU Mobile. Both parts have an average benchmark score of zero and hold the 50th percentile position among all GPUs tracked in the database. Without recorded performance measurements, a numerical head-to-head comparison cannot be constructed from the available data.

The AMD Steam Machine GPU does present specifications that suggest substantially higher theoretical throughput. Its FP32 compute is rated at 17.56 TFLOPS, while the Intel Arc Graphics 48EU Mobile delivers 1,382.4 GFLOPS in FP32. That places AMD's part at roughly 12.7 times the raw single-precision compute of Intel's mobile graphics solution. Pixel fill rates differ similarly: the AMD GPU reaches 156.8 GPixel/s against 14.40 GPixel/s for Intel, a factor of about 10.9. Texture fill rate shows a comparable gap, with the AMD part at 274.4 GTexel/s versus 43.20 GTexel/s.

Memory bandwidth further separates the two. The AMD Steam Machine GPU uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Intel part uses system shared memory with bandwidth described as system dependent, meaning it has no dedicated VRAM allocation. The AMD memory clock is listed at 2250 MHz with 18 Gbps effective transfer rate.

Clock speeds also differ markedly. AMD's base clock is 1720 MHz with a boost of 2450 MHz and a game clock of 2250 MHz. Intel's base is 300 MHz with a boost of 1800 MHz and no listed game clock. Even at maximum boost, Intel's clock is 650 MHz lower than AMD's base frequency.

Both GPUs support DirectX 12, OpenGL 4.6, and Vulkan 1.4. The AMD part supports DirectX 12 Ultimate (12_2), which includes additional features compared to Intel's DirectX 12 (12_1) support. The AMD GPU also lists 28 ray tracing cores, while the Intel part has no ray tracing core count specified.

The Verdict

The recorded data shows two GPUs aimed at entirely different segments. The AMD Steam Machine GPU is a discrete console-oriented part with a 110 W TDP, designed for Valve's Steam Machine platform. The Intel Arc Graphics 48EU Mobile is a 28 W integrated graphics processor built into Meteor Lake mobile chips.

For gaming workloads where dedicated VRAM and high fill rates matter, the AMD Steam Machine GPU is the clear choice based on specifications alone. Its 8 GB of GDDR6 memory at 288.0 GB/s bandwidth, combined with 1792 shading units and 28 ray tracing cores, places it far above the Intel part's 384 shading units and shared memory architecture.

The Intel Arc Graphics 48EU Mobile is better suited for portable devices where power draw is a primary concern. Its 28 W TDP is substantially lower than AMD's 110 W, making it appropriate for thin-and-light laptops or devices where battery life takes priority over raw graphics performance.

Users who need no external power connectors will find that the AMD Steam Machine GPU lists power connectors as none, which is notable for a discrete GPU. The Intel part is an integrated solution, so it draws power through the host system's power delivery.

Where Each One Wins

The AMD Steam Machine GPU wins decisively in every raw performance metric recorded: FP32 compute, pixel fill rate, texture fill rate, memory bandwidth, shading units, texture mapping units, and raster operation units. It also has dedicated VRAM, which avoids the performance variability inherent in system shared memory.

The Intel Arc Graphics 48EU Mobile wins on power efficiency in terms of absolute consumption, drawing 28 W against AMD's 110 W. It also offers portability advantages since it integrates directly into the processor package, whereas the AMD part is a separate discrete card measuring 156 mm by 152 mm by 162 mm.

The AMD part supports DirectX 12 Ultimate with feature level 12_2, which includes mesh shaders, variable rate shading, and other modern rendering features that the Intel part's DirectX 12 (12_1) does not fully cover. This matters for games that use these advanced API features.

The Intel part uses a ring bus interface, while the AMD part has no bus interface listed. This reflects the integrated nature of Intel's solution versus the standalone card design of AMD's GPU.

FAQ

Q: Which GPU has more raw compute power?

A: The AMD Steam Machine GPU delivers 17.56 TFLOPS of FP32 performance, compared to 1,382.4 GFLOPS for the Intel Arc Graphics 48EU Mobile. The AMD part is approximately 12.7 times faster in this metric.

Q: Does either GPU have dedicated video memory?

A: The AMD Steam Machine GPU has 8 GB of GDDR6 memory on a 128-bit bus with 288.0 GB/s bandwidth. The Intel Arc Graphics 48EU Mobile uses system shared memory with system dependent bandwidth.

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 manufactured on a 6 nm process at TSMC and contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter.

The Intel Arc Graphics 48EU Mobile is based on the Meteor Lake chip using Xe-LPG architecture. It falls under the Arc Graphics-M (Meteor Lake) generation. Intel fabricates this chip on a 10 nm process at its own foundry. The database does not record transistor count, die size, or transistor density for this part.

The AMD GPU uses 1792 shading units, 112 texture mapping units, 64 raster operation units, and 28 ray tracing cores. The Intel part has 384 shading units, 24 texture mapping units, and 8 raster operation units, with no ray tracing core count listed.

Memory architecture differs fundamentally. AMD uses dedicated GDDR6 memory with a fixed 128-bit bus and a peak bandwidth of 288.0 GB/s. Intel relies on system shared memory, meaning the GPU accesses the same memory pool as the CPU, with bandwidth dependent on the host system.

Clock behavior also diverges. The AMD GPU has a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2450 MHz. The Intel part operates at a much lower 300 MHz base and 1800 MHz boost. The AMD memory clock is 2250 MHz with 18 Gbps effective data rate.
