AMD Steam Deck OLED GPU vs NVIDIA GeForce RTX 5070 SUPER Comparison

AMD Steam Deck OLED GPU and NVIDIA GeForce RTX 5070 SUPER occupy opposite ends of the graphics spectrum, one designed for a handheld console and the other for high-performance desktop systems. The recorded data shows a clear performance hierarchy, but the two parts serve entirely different physical and thermal envelopes. This analysis examines the benchmark results, architectural choices, and specification gaps that define their separation.

Where Each One Wins

The AMD Steam Deck OLED GPU wins in the category of power efficiency relative to its physical size, as it operates with a 15 W TDP while delivering a full DirectX 12 Ultimate feature set. Its 16 GB of LPDDR5 memory on a 128 bit bus provides 176.0 GB/s of bandwidth, which is generous for a handheld-class part. The Steam Deck OLED GPU also wins on portability: its 298 mm length, 117 mm height, and 49 mm width include the entire handheld device, not just a card. The single USB Type-C display output reflects its integration into a mobile gaming system rather than a multi-monitor desktop setup.

The NVIDIA GeForce RTX 5070 SUPER wins in every raw performance metric recorded. Its 3DMark Steel Nomad DX12 score of 2690 places it in the 18th percentile among all GPUs in the database, which indicates it outperforms the vast majority of recorded graphics hardware. The AMD part sits at the 50th percentile with an average benchmark score of 0, meaning it has no recorded benchmark entries in this database. The RTX 5070 SUPER also wins on memory capacity with 18 GB of GDDR7, on bandwidth with 672.0 GB/s, and on compute throughput with 32.15 TFLOPS FP32 versus 1.638 TFLOPS for the AMD chip.

The use-case split is straightforward. The Steam Deck OLED GPU is a self-contained console GPU that prioritizes battery life and compact integration. The RTX 5070 SUPER is a desktop add-in board with a dual-slot cooler, a 16-pin power connector, and PCIe 5.0 x16 interface, designed for sustained high-frame-rate gaming at high resolutions. The data shows no overlap in their intended deployment scenarios.

Architecture Differences

The two GPUs come from different fabrication nodes and different design generations. The AMD Steam Deck OLED GPU uses the Sephiroth chip built on RDNA 2.0 architecture. It is manufactured on a 6 nm process at TSMC, packing 2,400 million transistors into a 131 mm² die. The transistor density measures 18.3 million per square millimeter. The NVIDIA GeForce RTX 5070 SUPER uses the GB205 chip on Blackwell 2.0 architecture, also made by TSMC but on a 5 nm process. It contains 31,100 million transistors across a 263 mm² die, achieving a density of 118.3 million per square millimeter.

The core configurations diverge massively. The AMD part has 512 shading units, 32 texture mapping units, 16 raster output units, and 8 ray tracing cores. The NVIDIA part has 6400 shading units, 200 texture mapping units, 80 raster output units, 50 ray tracing cores, and 200 tensor cores. The AMD GPU has no tensor cores listed, while the RTX 5070 SUPER includes them for AI-accelerated workloads.

Clock speeds reflect their power budgets. The AMD chip runs at a 1000 MHz base clock and 1600 MHz boost clock. The NVIDIA chip runs at 2325 MHz base and 2512 MHz boost. Memory clocks also differ: AMD uses 1375 MHz with 11 Gbps effective data rate, while NVIDIA uses 1750 MHz with 28 Gbps effective.

API support shows a small divergence. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD GPU supports Vulkan 1.3, while the NVIDIA GPU supports Vulkan 1.4. Both are listed as active production parts.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The only recorded benchmark for either part is the RTX 5070 SUPER's 3DMark Steel Nomad DX12 score of 2690. The Steam Deck OLED GPU has no benchmark scores in the database, and its average benchmark score is listed as 0.

The RTX 5070 SUPER's nearest rivals in the database provide context for its measured performance. The NVIDIA Quadro K1100M scores 2664, which is 1% behind the RTX 5070 SUPER. The NVIDIA GeForce GT 1030 scores 2662, also 1.1% behind. The Intel Arc Pro B50 scores 2660, again 1.1% behind. The NVIDIA GeForce GT 440 scores 2645, which is 1.7% behind. These deltas are small, indicating that the Steel Nomad score of 2690 places the RTX 5070 SUPER in a narrow band above these older or lower-tier parts.

The absence of any recorded benchmark for the Steam Deck OLED GPU means its relative position cannot be quantified from direct measurements. Its 50th percentile ranking among all GPUs is a database classification, not a derived score. The RTX 5070 SUPER's 18th percentile ranking means it sits above 82% of all GPUs in the database, a strong position for a desktop part.

Specification Differences

The two parts differ in nearly every measurable specification. The process nodes are 6 nm for AMD versus 5 nm for NVIDIA. Transistor counts are 2,400 million versus 31,100 million. Die sizes are 131 mm² versus 263 mm². Transistor densities are 18.3M per mm² versus 118.3M per mm².

Memory configurations diverge completely. The AMD GPU uses 16 GB of LPDDR5 with a 128 bit bus and 176.0 GB/s bandwidth. The NVIDIA GPU uses 18 GB of GDDR7 with a 192 bit bus and 672.0 GB/s bandwidth. Memory clock rates are 1375 MHz (11 Gbps effective) for AMD versus 1750 MHz (28 Gbps effective) for NVIDIA.

Compute resources show a 12.5x difference in shading units (512 versus 6400), a 6.25x difference in texture mapping units (32 versus 200), and a 5x difference in raster output units (16 versus 80). Ray tracing cores number 8 versus 50, and tensor cores are absent on the AMD part versus 200 on the NVIDIA part.

Pixel and texture rates scale accordingly. The AMD GPU delivers 25.60 GPixel/s and 51.20 GTexel/s. The NVIDIA GPU delivers 201.0 GPixel/s and 502.4 GTexel/s. FP32 throughput is 1.638 TFLOPS versus 32.15 TFLOPS. FP16 throughput is 3.277 TFLOPS (2:1 ratio) for AMD versus 32.15 TFLOPS (1:1 ratio) for NVIDIA.

Power consumption differs by an order of magnitude: 15 W TDP for the AMD part versus 275 W for the NVIDIA part. Physical dimensions also differ: the AMD part measures 298 mm by 117 mm by 49 mm, while the NVIDIA card measures 245 mm by 115 mm by 40 mm. The NVIDIA card is dual-slot, uses a 16-pin power connector, and connects via PCIe 5.0 x16. The AMD part lists no slot width, power connector, or bus interface, reflecting its embedded console design.

Display outputs are 1x USB Type-C for the AMD GPU versus 1x HDMI 2.1b and 3x DisplayPort 2.1b for the NVIDIA GPU. Release dates are November 8, 2023 for the AMD part and December 31, 2025 for the NVIDIA part. Both have no predecessor or successor listed in the database.
