AMD Steam Deck OLED GPU vs Intel Arc B370 Comparison

AMD Steam Deck OLED GPU and Intel Arc B370 occupy opposite ends of the mobile graphics spectrum, and the recorded data confirms a clear split in capability. The AMD part, built on RDNA 2.0, is a 15 W console GPU designed for a fixed handheld form factor, while the Intel Arc B370 is a 25 W integrated graphics solution for Panther Lake mobile processors. The benchmark data shows the Intel Arc B370 delivering a 3DMark Steel Nomad DX12 score of 1184, which places it at the 5th percentile of all GPUs, a low standing that reflects its integrated nature. The AMD Steam Deck OLED GPU, with no recorded benchmark scores in the database, holds a 50th percentile ranking, indicating a far stronger relative position among all tracked GPUs. The Intel part edges out several older discrete and mobile GPUs, including the ATI Mobility Radeon HD 5570, which scored 1186, a delta of -0.2%, and the AMD Radeon HD 7650M at 1192, a delta of -0.7%. These figures show the Arc B370 trading blows with decade-old hardware, while the AMD console GPU sits in the middle of the overall performance distribution, a far more competitive position.

Where Each One Wins

The Intel Arc B370 wins in raw compute throughput and memory bandwidth flexibility. Its FP32 performance is 6.144 TFLOPS, nearly four times the AMD Steam Deck OLED GPU's 1.638 TFLOPS, and its FP16 output of 12.29 TFLOPS dwarfs the AMD part's 3.277 TFLOPS. The Intel GPU also has more execution resources, with 1280 shading units, 40 texture mapping units, and 20 render output units, compared to the AMD GPU's 512 shading units, 32 TMUs, and 16 ROPs. These advantages translate directly into a higher pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s, versus 25.60 GPixel/s and 51.20 GTexel/s for the AMD part. For compute-heavy workloads and higher-resolution rendering, the Intel Arc B370 holds a decisive edge on paper.

The AMD Steam Deck OLED GPU wins in efficiency and integration. It operates at a 15 W TDP, 10 W lower than the Intel Arc B370's 25 W, yet it still lands at the 50th percentile of all GPUs, a far higher standing than the Intel part's 5th percentile. The AMD GPU also has a higher base clock of 1000 MHz compared to the Intel part's 300 MHz, though the Intel GPU boosts to 2400 MHz versus 1600 MHz for the AMD part. The AMD GPU uses 2,400 million transistors on a 131 mm² die, while the Intel part's transistor count and die size are listed as unknown, making a direct density comparison impossible. For sustained handheld gaming within a fixed power envelope, the AMD part's balance of performance and power consumption is the clear winner.

Architecture Differences

The two GPUs come from completely different architectural lineages. The AMD Steam Deck OLED GPU uses RDNA 2.0 architecture on a 6 nm process from TSMC, with a chip codenamed Sephiroth. The Intel Arc B370 uses Xe3-LPG architecture on a 3 nm process from Intel, with a chip codenamed Panther Lake. The process node difference is significant: 6 nm versus 3 nm, giving Intel a density advantage, though the AMD part's 2,400 million transistors and 131 mm² die size are the only physical metrics recorded. The Intel part's transistor count and die size are unknown, so no density calculation can be made from the data.

Feature support also differs. Both GPUs support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the Intel Arc B370 supports Vulkan 1.4, while the AMD Steam Deck OLED GPU supports Vulkan 1.3. The Intel GPU has 10 ray tracing cores versus 8 on the AMD part, a modest advantage in RT workloads. The AMD GPU uses dedicated LPDDR5 memory with a 128-bit bus and 176.0 GB/s bandwidth, while the Intel GPU relies on system shared memory with system-dependent bandwidth, a fundamental difference in memory architecture. The AMD part's fixed 16 GB LPDDR5 pool provides predictable bandwidth, while the Intel part's shared memory approach offers flexibility but no guaranteed throughput.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Steam Deck OLED GPU and the Intel Arc B370. The only recorded benchmark score belongs to the Intel Arc B370, which scored 1184 in 3DMark Steel Nomad DX12. This score places the Intel part at the 5th percentile of all GPUs and puts it in close competition with several older GPUs. The ATI Mobility Radeon HD 5570 scored 1186, just 0.2% higher, and the ATI Radeon HD 5770 scored 1190, 0.5% higher. The AMD Radeon HD 7650M scored 1192, 0.7% higher, while the AMD FirePro M2000 scored 1168, which is 1.4% lower than the Arc B370. These delta values show the Arc B370 performing within 1.5% of a group of GPUs from the early 2010s, a clear indication of its modest absolute performance level.

The AMD Steam Deck OLED GPU has no recorded benchmark scores in the database, so its performance must be inferred from its 50th percentile ranking and its hardware specifications. Its FP32 throughput of 1.638 TFLOPS is roughly a quarter of the Intel part's 6.144 TFLOPS, and its pixel rate of 25.60 GPixel/s is just over half of the Intel part's 48.00 GPixel/s. However, the AMD part's 50th percentile standing suggests that its real-world performance, within the context of its 15 W TDP and handheld form factor, is far more competitive relative to the broader GPU landscape than the Intel part's 5th percentile ranking. The Intel Arc B370's raw compute advantage does not translate into a strong overall performance ranking, likely due to its integrated nature and system-dependent memory bandwidth.

Specification Differences

The two GPUs differ across nearly every major specification category. The AMD Steam Deck OLED GPU uses a 6 nm TSMC process, while the Intel Arc B370 uses a 3 nm Intel process. The AMD part has 2,400 million transistors on a 131 mm² die, while the Intel part's transistor count and die size are unknown. Clock speeds differ substantially: the AMD GPU has a 1000 MHz base and 1600 MHz boost, while the Intel GPU has a 300 MHz base and 2400 MHz boost. Memory configurations are fundamentally different: the AMD GPU uses 16 GB of LPDDR5 on a 128-bit bus with 176.0 GB/s bandwidth, while the Intel GPU uses system shared memory with system-dependent bandwidth and no dedicated memory specifications.

Compute resources favor the Intel part: 1280 shading units versus 512, 40 TMUs versus 32, 20 ROPs versus 16, and 10 RT cores versus 8. The Intel GPU also leads in throughput, with 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 versus 1.638 TFLOPS and 3.277 TFLOPS for the AMD part. Pixel rate is 48.00 GPixel/s versus 25.60 GPixel/s, and texture rate is 96.00 GTexel/s versus 51.20 GTexel/s. Power consumption favors the AMD part: 15 W versus 25 W. The Intel GPU is an integrated graphics processor with no power connectors and no dedicated slot width, while the AMD GPU is a standalone console GPU with a 298 mm length, 117 mm height, and 49 mm width, and a single USB Type-C display output. The Intel part's display outputs are listed as portable device dependent. API support is nearly identical, with both offering DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the Intel GPU supports Vulkan 1.4 versus Vulkan 1.3 on the AMD part. The AMD GPU was released on 2023-11-08, while the Intel Arc B370 has a release date of 2026-01-26.

The Verdict

The data points to a straightforward choice based on use case. The Intel Arc B370 is the stronger compute part on paper, with 6.144 TFLOPS FP32, 1280 shading units, and a 2400 MHz boost clock, but its 5th percentile ranking and benchmark proximity to GPUs like the ATI Radeon HD 5770, which scored 1190, indicate that raw specifications do not translate into a strong competitive position. Its reliance on system shared memory and its 25 W TDP further limit its applicability. The AMD Steam Deck OLED GPU, despite lower compute specifications, holds a 50th percentile ranking, a far stronger relative position, and operates at a lower 15 W TDP. For a fixed handheld console with a dedicated 16 GB LPDDR5 pool and 176.0 GB/s bandwidth, the AMD part is the better-integrated solution. For compute-heavy tasks in a mobile processor context, the Intel Arc B370 offers higher throughput, but the absence of any recorded benchmark score for the AMD part makes a direct performance comparison impossible. The recorded data shows the AMD part as the better-rounded GPU, while the Intel part is the higher-specification but lower-ranked alternative.
