AMD Steam Machine GPU vs Intel Arc A380M Comparison

Head-to-Head Benchmarks

The database does not contain any recorded head-to-head benchmark matches between the AMD Steam Machine GPU and the Intel Arc A380M. Both entries show an empty benchmark array, zero win counts for each side, and no nearest rival data. Consequently, there are no exact scores, percentile deltas, or comparative performance metrics to walk through in this section.

What the recorded data does show is a substantial gap in raw compute capability. The AMD Steam Machine GPU delivers 17.56 TFLOPS of FP32 throughput, while the Intel Arc A380M delivers 4.096 TFLOPS. That places the AMD part at roughly 4.3 times the FP32 output of the Intel part. In FP16, the AMD GPU again posts 17.56 TFLOPS with a 1:1 ratio, whereas the Intel Arc A380M reaches 8.192 TFLOPS with a 2:1 ratio. The AMD part still leads here, but the margin narrows to about 2.1 times.

Texture and pixel throughput follow the same direction. The AMD Steam Machine GPU sustains 274.4 GTexel/s and 156.8 GPixel/s. The Intel Arc A380M manages 128.0 GTexel/s and 64.00 GPixel/s. These figures indicate the AMD GPU maintains more than double the texture fill rate and roughly 2.45 times the pixel fill rate of the Intel mobile part.

Memory bandwidth also favors the AMD Steam Machine GPU. It uses an 8 GB GDDR6 frame buffer on a 128 bit bus, producing 288.0 GB/s of bandwidth. The Intel Arc A380M uses 6 GB GDDR6 on a 96 bit bus, yielding 186.0 GB/s. The AMD part offers 55% more bandwidth, which matters for higher resolution textures and data-heavy workloads.

Both GPUs share the same API feature set. Each supports DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. Ray tracing hardware exists on both, with the AMD part carrying 28 RT cores versus 8 RT cores on the Intel part. Neither GPU has dedicated tensor cores listed in the database.

The percentile rankings against all GPUs are identical: both sit at the 50th percentile. With no benchmark scores recorded in the database, this percentile value cannot be tied to any specific measured performance delta. The absence of head-to-head results means all comparisons here derive solely from the specification-level data captured for each product.

Architecture Differences

The two GPUs come from different architectural families. The AMD Steam Machine GPU is built on RDNA 3.0, using the Navi 33 chip with the codename Hotpink Bonefish. It belongs to the Console GPU generation for Valve. The Intel Arc A380M uses the Xe-HPG architecture, built on the DG2-128 chip, and belongs to the Alchemist generation within the Arc 3 Mobile lineup.

Both are fabricated by TSMC on a 6 nm process. The AMD chip integrates 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The Intel chip integrates 7,200 million transistors on a 157 mm² die, giving a density of 45.9 million per square millimeter. The AMD die is larger and denser, which aligns with its higher compute resource count.

The compute resource layout differs significantly. The AMD Steam Machine GPU has 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The Intel Arc A380M has 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores. These differences directly explain the fill rate and TFLOPS gaps observed in the specification data.

Clock behavior also differs. The AMD GPU lists a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. Its memory runs at 2250 MHz with 18 Gbps effective data rate. The Intel GPU lists a base clock of 1550 MHz and a boost clock of 2000 MHz, with no game clock specified. Its memory runs at 1937 MHz with 15.5 Gbps effective data rate. The AMD part operates at higher frequencies across both core and memory.

Power delivery and form factor represent another architectural split. The AMD Steam Machine GPU has a TDP of 110 W and lists no power connectors, suggesting an integrated or fixed power solution within its console context. The Intel Arc A380M has a TDP of 35 W, uses an MXM Module slot width, and connects via an MXM-A (3.1) bus interface. These are fundamentally different physical designs: one aimed at a fixed console implementation, the other at modular mobile graphics.

Where Each One Wins

The AMD Steam Machine GPU wins decisively on raw compute throughput. Its 17.56 TFLOPS FP32 output, 274.4 GTexel/s texture rate, and 156.8 GPixel/s pixel rate place it far ahead of the Intel Arc A380M in any workload that scales with shading units, TMUs, ROPs, or clock speed. The 28 RT cores give it a structural advantage in ray-traced scenes, though the database provides no measured ray tracing benchmarks to confirm real-world scaling.

The AMD part also wins on memory capacity and bandwidth. The 8 GB frame buffer with 288.0 GB/s bandwidth handles larger textures and higher resolution buffers more comfortably than the 6 GB, 186.0 GB/s configuration of the Intel part. The higher boost clock of 2450 MHz versus 2000 MHz further reinforces the AMD lead in peak throughput.

The Intel Arc A380M wins on power efficiency in absolute terms. Its 35 W TDP is less than one third of the 110 W TDP of the AMD Steam Machine GPU. For systems constrained by thermal envelopes or battery life, the Intel part draws far less power while still delivering a full DirectX 12 Ultimate feature set. Its MXM Module form factor and MXM-A (3.1) bus interface also give it an integration advantage in modular or replaceable mobile graphics solutions.

The Intel part also wins on release timing. It entered production in January 2023, while the AMD Steam Machine GPU carries a June 2026 release date. For applications that require an established, available mobile GPU, the Intel Arc A380M has been in the field for years longer.

Neither GPU has recorded benchmark wins in the database. Both sit at the 50th percentile among all GPUs, and neither has nearest rival data. The use-case split therefore rests entirely on the specification differences above.

The Verdict

The data supports a clear division of roles. The AMD Steam Machine GPU is the stronger performer on every compute and memory metric recorded. It delivers 17.56 TFLOPS FP32, 288.0 GB/s bandwidth, 8 GB of VRAM, and 28 RT cores. For gaming or GPU compute workloads that demand maximum throughput within a fixed console platform, this part is the obvious choice. Its 110 W TDP and lack of power connectors indicate a design intended for a dedicated, actively cooled enclosure rather than a portable or modular system.

The Intel Arc A380M is the appropriate pick for low-power, modular mobile applications. Its 35 W TDP, MXM Module form factor, and MXM-A (3.1) bus interface make it suitable for laptops or embedded systems where power budget and serviceability matter more than raw performance. It still supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so it carries the same API compatibility as the AMD part. However, its 4.096 TFLOPS FP32 output and 6 GB memory capacity place it in a different performance class entirely.

Given the absence of recorded benchmark scores, head-to-head results, and nearest rival comparisons in the database, any performance verdict must rely on the specification-level data. That data shows the AMD Steam Machine GPU outperforming the Intel Arc A380M by wide margins in FP32 throughput, texture rate, pixel rate, memory bandwidth, and ray tracing core count. The Intel Arc A380M counters with a much lower TDP and a modular form factor suited to different hardware contexts.

The choice between these two GPUs depends on the target system design. A fixed console platform with adequate cooling and power delivery should use the AMD Steam Machine GPU for its superior compute resources. A power-sensitive mobile or modular system should use the Intel Arc A380M for its low draw and replaceable MXM interface. The database does not provide any measured evidence that the Intel part closes the performance gap, so the AMD part remains the higher-performing option on all recorded metrics.
