AMD Steam Deck OLED GPU vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark scores between the AMD Steam Deck OLED GPU and the Intel Arc A380E x2. Both products hold the same 50th percentile position among all GPUs in the database, with an average benchmark score of 0 for each. The absence of measured wins for either side means the comparison must rely entirely on architectural specifications and derived performance figures.

The raw compute numbers, however, tell a clear story. The Intel Arc A380E x2 delivers 4.096 TFLOPS of FP32 throughput, which is 2.5 times the 1.638 TFLOPS offered by the AMD Steam Deck OLED GPU. The gap is equally pronounced in texture work: the Intel part reaches 128.0 GTexel/s against 51.20 GTexel/s for AMD, a 2.5x advantage. Pixel throughput follows the same pattern, with Intel at 64.00 GPixel/s versus AMD's 25.60 GPixel/s, again a 2.5x difference in favor of the Arc A380E x2.

These ratios are consistent across the board, which indicates the Intel product's advantage is structural rather than workload-specific. The Arc A380E x2 has double the shading units (1024 versus 512), double the texture mapping units (64 versus 32), and double the render output units (32 versus 16). Every parallel processing resource is doubled, and the clock speed is higher as well, so the resulting throughput advantage is uniform.

The AMD part does not win any measured benchmark category in the database. Its wins counter is 0, as is Intel's. The comparison is therefore one of theoretical peak rates and architectural capability, not observed application performance. The database shows no recorded frame rates, no synthetic test scores, and no power-normalized efficiency metrics for either product.

Architecture Differences

Both GPUs are built on a 6 nm process at TSMC, but the similarities end there. The AMD Steam Deck OLED GPU uses the Sephiroth chip with RDNA 2.0 architecture, part of the Console GPU generation from Valve. The Intel Arc A380E x2 uses the DG2-128 chip with Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation.

The transistor counts differ substantially. Intel's DG2-128 packs 7,200 million transistors on a 157 mm² die, yielding a transistor density of 45.9 million per square millimeter. AMD's Sephiroth contains 2,400 million transistors on a smaller 131 mm² die, for a density of 18.3 million per square millimeter. Intel achieves 3 times the transistor count on a die that is only 20% larger, reflecting a far denser design.

Both GPUs include 8 ray tracing cores, so hardware-accelerated ray tracing capability is present on both sides. Neither product lists tensor cores, so AI acceleration hardware is absent from both. The API support is nearly identical: both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Intel part supports Vulkan 1.4, while the AMD part supports Vulkan 1.3.

Memory architecture diverges sharply. The AMD Steam Deck OLED GPU uses 16 GB of LPDDR5 on a 128-bit bus, delivering 176.0 GB/s of bandwidth. The Intel Arc A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The Intel memory runs at 1937 MHz with 15.5 Gbps effective speed, while the AMD memory runs at 1375 MHz with 11 Gbps effective. Despite having a narrower bus and less than half the capacity, the Intel card achieves slightly higher bandwidth thanks to faster memory technology.

Power delivery is another major architectural split. The AMD part is rated at 15 W TDP, a figure consistent with an integrated, power-constrained console design. The Intel Arc A380E x2 is rated at 130 W TDP, requires a single 6-pin power connector, and suggests a 300 W power supply. The Intel card is a discrete, single-slot solution with a PCIe 4.0 x8 bus interface, while the AMD GPU has no listed bus interface and exposes only a single USB Type-C display output.

Where Each One Wins

The AMD Steam Deck OLED GPU wins on memory capacity and power efficiency. Its 16 GB of LPDDR5 is nearly 3 times the 6 GB available on the Intel Arc A380E x2, which matters for workloads that exceed the smaller frame buffer. The 15 W TDP is dramatically lower than Intel's 130 W, so the AMD solution is suitable for tightly integrated, low-power devices where thermal and battery constraints dominate. The AMD die is also smaller at 131 mm², which reduces manufacturing cost per wafer even if the transistor density is lower.

The Intel Arc A380E x2 wins on raw compute throughput, texture fill, pixel fill, and memory bandwidth. Its 4.096 TFLOPS FP32 performance is more than double the AMD part, and its 128.0 GTexel/s texture rate is similarly doubled. The 186.0 GB/s memory bandwidth edges out AMD's 176.0 GB/s. The Intel card also supports more display outputs with 8x mini-DisplayPort 2.0 connections, compared to the single USB Type-C on the AMD GPU. The Intel part supports Vulkan 1.4, a newer version than AMD's Vulkan 1.3.

The AMD GPU remains in active production with a release date of 2023-11-08. The Intel Arc A380E x2, released on 2024-03-31, is marked as end-of-life. The Intel part has a predecessor (Xe Graphics) and a successor (Battlemage) listed, while the AMD part has neither.

Specification Differences

The two GPUs differ in every major specification category. The AMD Steam Deck OLED GPU uses the Sephiroth chip with RDNA 2.0 architecture, while the Intel Arc A380E x2 uses the DG2-128 chip with Xe-HPG architecture. Both are 6 nm TSMC parts, but Intel's die is 157 mm² versus AMD's 131 mm², and Intel packs 7,200 million transistors versus AMD's 2,400 million.

Clock speeds favor Intel significantly. The Arc A380E x2 runs at a fixed 2000 MHz for both base and boost, while the AMD part runs at 1000 MHz base and 1600 MHz boost. Memory clocks also favor Intel: 1937 MHz (15.5 Gbps effective) versus AMD's 1375 MHz (11 Gbps effective).

The compute unit counts are doubled on Intel: 1024 shading units versus 512, 64 TMUs versus 32, and 32 ROPs versus 16. Both have 8 ray tracing cores. FP16 performance follows the FP32 ratio, with Intel at 8.192 TFLOPS (2:1) versus AMD's 3.277 TFLOPS (2:1).

Memory capacity and type differ: 16 GB LPDDR5 on AMD versus 6 GB GDDR6 on Intel. Bus width is 128-bit on AMD and 96-bit on Intel, but bandwidth is 176.0 GB/s on AMD and 186.0 GB/s on Intel. Power consumption is 15 W on AMD versus 130 W on Intel.

Physical dimensions differ as well. The AMD part measures 298 mm in length, 117 mm in height, and 49 mm in width. The Intel card measures 265 mm in length, 127 mm in height, and 20 mm in width, and is explicitly listed as single-slot. The Intel card has a PCIe 4.0 x8 interface and a 6-pin power connector, while the AMD part lists neither. Display outputs are 1x USB Type-C on AMD and 8x mini-DisplayPort 2.0 on Intel.

The Verdict

The data splits this comparison cleanly into two distinct use profiles. The AMD Steam Deck OLED GPU is the choice for integrated, low-power applications. Its 15 W TDP, 16 GB memory capacity, and compact 131 mm² die make it suited for handheld or embedded contexts where power draw and physical footprint are the primary constraints. It remains in active production, which suggests ongoing availability for such designs.

The Intel Arc A380E x2 is the choice for raw graphics throughput in a discrete card format. Its 2.5x advantage in FP32, texture rate, and pixel rate, combined with its 186.0 GB/s memory bandwidth, 8x mini-DisplayPort 2.0 outputs, and PCIe 4.0 x8 interface, position it as a more capable rendering solution for systems that can supply 130 W and a 6-pin power connector. The trade-off is clear: the Intel card requires over 8 times the power budget to deliver its performance.

The 50th percentile ranking for both GPUs in the database indicates neither is positioned at the top of the overall GPU hierarchy, but within their respective categories, they serve different masters. Buyers needing maximum throughput per watt should favor the AMD part. Buyers needing maximum absolute throughput and multiple display outputs should favor the Intel part, provided the end-of-life status and higher power requirement are acceptable. The Intel part's successor, Battlemage, is already listed, which may factor into long-term planning.
