AMD Steam Deck OLED GPU vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for the AMD Steam Deck OLED GPU against the Intel Arc G3. Both products show an average benchmark score of 0, and neither lists any nearest rivals. The AMD Steam Deck OLED GPU holds a percentile rank of 50 among all GPUs, and the Intel Arc G3 also holds a percentile rank of 50. With no measured performance data available, direct numerical comparisons of frame rates, rendering throughput, or compute workloads cannot be established from the recorded information.

What can be compared directly are the theoretical peak rates derived from the specifications. The Intel Arc G3 delivers 6.144 TFLOPS of FP32 compute, which is 3.75 times the AMD Steam Deck OLED GPU's 1.638 TFLOPS. In FP16, the Intel part reaches 12.29 TFLOPS (2:1), compared to 3.277 TFLOPS (2:1) for the AMD part. Texture fill rates follow the same pattern: the Intel Arc G3 produces 96.00 GTexel/s versus 51.20 GTexel/s for the AMD Steam Deck OLED GPU. Pixel throughput also favors Intel, with 48.00 GPixel/s against 25.60 GPixel/s.

The AMD Steam Deck OLED GPU's advantage lies in efficiency and packaging. Its 15 W TDP is 10 W lower than the Intel Arc G3's 25 W TDP, which represents a 40% reduction in power draw. The AMD part also has a dedicated 16 GB LPDDR5 memory subsystem with a 128 bit bus and 176.0 GB/s bandwidth, whereas the Intel Arc G3 relies on System Shared memory with bandwidth described as System Dependent. These figures indicate that the AMD GPU is designed around a fixed, self-contained memory pool, while the Intel GPU depends entirely on the host platform's memory configuration.

Where Each One Wins

The Intel Arc G3 wins in every category of theoretical peak throughput. Its FP32 compute is 3.75 times higher, its texture rate is 1.875 times higher, and its pixel rate is 1.875 times higher. The shading unit count of 1280 versus 512, texture mapping units of 40 versus 32, and render output units of 20 versus 16 all contribute to this advantage. The boost clock of 2400 MHz versus 1600 MHz further supports the higher throughput figures. For workloads that scale with raw shader count and clock speed, such as high-resolution rendering or compute-heavy effects, the Intel part has a clear specification-level edge.

The AMD Steam Deck OLED GPU wins in power efficiency and memory autonomy. Its 15 W TDP is 40% lower than Intel's 25 W TDP, meaning the AMD part delivers its 1.638 TFLOPS while drawing two-thirds of the power of the Intel part. The dedicated 16 GB LPDDR5 pool with 176.0 GB/s bandwidth also provides a fixed, predictable memory environment. The Intel Arc G3's System Shared memory could offer higher raw bandwidth if paired with sufficiently fast system memory, but the database records no specific figures, so no comparison of achieved memory performance is possible. The AMD GPU's integrated design, with its 298 mm length, 117 mm height, and 49 mm width, also packages the entire memory subsystem into the device itself.

The AMD part also has a longer production history, with a release date of 2023-11-08, while the Intel Arc G3 lists a release date of 2026-05-31. Both remain in Active production status.

Specification Differences

The two GPUs differ across nearly every recorded specification. The AMD Steam Deck OLED GPU uses the Sephiroth chip built on RDNA 2.0 architecture, fabricated on a 6 nm TSMC process with 2,400 million transistors on a 131 mm² die, yielding a transistor density of 18.3M per mm². The Intel Arc G3 uses the Panther Lake chip built on Xe3-LPG architecture, fabricated on a 3 nm Intel process, with transistor count and die size listed as unknown.

Clock speeds differ substantially: AMD runs at 1000 MHz base and 1600 MHz boost, while Intel runs at 300 MHz base and 2400 MHz boost. Memory configurations are entirely different: AMD uses 16 GB LPDDR5 with a 128 bit bus and 176.0 GB/s bandwidth, while Intel uses System Shared memory with System Shared type, bus width, and System Dependent bandwidth.

Compute resources differ: AMD has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. Intel has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. Pixel rate is 25.60 GPixel/s for AMD versus 48.00 GPixel/s for Intel. Texture rate is 51.20 GTexel/s versus 96.00 GTexel/s. FP32 is 1.638 TFLOPS versus 6.144 TFLOPS. FP16 is 3.277 TFLOPS versus 12.29 TFLOPS.

Power draw differs by 10 W: 15 W for AMD, 25 W for Intel. The Intel part is an IGP with no power connectors, no slot width beyond the IGP designation, and display outputs described as Portable Device Dependent. The AMD part has a single USB Type-C display output. The AMD part has physical dimensions of 298 mm by 117 mm by 49 mm; the Intel part lists no dimensions. The AMD part has a release date of 2023-11-08; the Intel part lists 2026-05-31.

Architecture Differences

The AMD Steam Deck OLED GPU uses RDNA 2.0 architecture, while the Intel Arc G3 uses Xe3-LPG architecture. These are fundamentally different GPU designs from different manufacturers. AMD's chip, Sephiroth, is built on a 6 nm TSMC process and integrates 2,400 million transistors. Intel's chip, Panther Lake, is built on a 3 nm Intel process, with transistor count not recorded.

The ray tracing capabilities differ in scale: AMD includes 8 ray tracing cores, while Intel includes 10. Both support DirectX 12 Ultimate (12_2), confirming hardware ray tracing and mesh shaders on both parts. The Vulkan support differs, with AMD at version 1.3 and Intel at version 1.4. Both support OpenGL 4.6.

The memory architecture represents the most significant architectural split. AMD integrates 16 GB of LPDDR5 directly with the GPU, using a 128 bit interface. Intel's Arc G3 uses System Shared memory, meaning it has no dedicated VRAM and instead accesses the host system's memory. This makes the Intel part dependent on the host platform for both capacity and bandwidth, while the AMD part is self-contained. The AMD part's memory clock is 1375 MHz with 11 Gbps effective data rate; the Intel part's memory clock is not applicable because it uses system memory.

The process node difference is substantial: 6 nm at TSMC versus 3 nm at Intel. The smaller node gives Intel a potential density and power efficiency advantage at the transistor level, though the Intel part's higher TDP of 25 W versus 15 W shows that the design targets different power envelopes. The AMD part's lower base clock of 1000 MHz versus Intel's 300 MHz suggests different power management strategies, while the boost clocks of 1600 MHz versus 2400 MHz indicate Intel's design favors higher peak clocks.

The Verdict

The recorded data shows two GPUs with opposing design philosophies. The Intel Arc G3 is the higher-performance part by every theoretical measure in the database. Its 6.144 TFLOPS FP32 output, 96.00 GTexel/s texture rate, and 48.00 GPixel/s pixel rate place it clearly ahead of the AMD Steam Deck OLED GPU's 1.638 TFLOPS, 51.20 GTexel/s, and 25.60 GPixel/s. The Intel part also has more shading units, more TMUs, more ROPs, more ray tracing cores, and a higher boost clock. Any workload that is limited by shader throughput, texture fetching, or pixel fill will favor the Intel Arc G3.

The AMD Steam Deck OLED GPU wins on power draw, with a 15 W TDP versus 25 W for Intel, and on memory self-sufficiency, with 16 GB of dedicated LPDDR5 delivering 176.0 GB/s. For a device where power consumption is a primary constraint, the AMD part delivers its performance at 60% of the Intel part's power budget. The AMD part's integrated memory also removes any dependency on host memory quality, whereas the Intel part's System Shared memory means its real-world bandwidth cannot be determined from the database.

For users choosing based on the recorded data, the decision hinges on the priority between peak throughput and power efficiency. The Intel Arc G3 is the choice for maximum compute and rendering performance, with 3.75 times the FP32 throughput and 40% more ray tracing cores. The AMD Steam Deck OLED GPU is the choice for power-constrained or self-contained systems, where its 15 W TDP and fixed 16 GB memory pool provide a complete, predictable graphics solution. The Intel part's 3 nm process and Vulkan 1.4 support represent newer technology, but the AMD part's longer production history and lower power envelope make it the more established and efficient option. Both GPUs hold identical percentile ranks of 50, and neither has recorded benchmark scores, so final performance judgments beyond the specification sheet remain unmeasured in the database.
