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

Where Each One Wins

The AMD Steam Deck OLED GPU and the NVIDIA GeForce RTX 5070 Mobile occupy entirely different positions in the database. The Steam Deck OLED GPU is a low-power console part built for a handheld form factor, while the RTX 5070 Mobile is a full mobile discrete GPU aimed at performance laptops. The recorded benchmark data shows a complete sweep for the NVIDIA part across every workload category, with the AMD part having no benchmark entries at all in the database. This means the Steam Deck OLED GPU cannot be evaluated on raw compute scores, while the RTX 5070 Mobile has nine recorded benchmark results spanning OpenCL, Vulkan, DirectX variants, 2D, 3D, and compute workloads.

The RTX 5070 Mobile wins on every measurable axis. Its Passmark G3D score of 20355 places it in the 75th percentile of all GPUs in the database, which is a strong position for a mobile part. The Steam Deck OLED GPU sits at the 50th percentile, but that figure is based on its overall hardware profile rather than any benchmark scores, since the database lists no benchmarks for it. The use-case split is therefore stark: the RTX 5070 Mobile is the only one of the two with recorded performance data, and it dominates across all of it.

The Steam Deck OLED GPU does have advantages in specific hardware characteristics that matter for its intended use case. It draws a TDP of 15 W, compared to 50 W for the RTX 5070 Mobile, and it integrates 16 GB of LPDDR5 memory, double the 8 GB of GDDR7 on the NVIDIA part. These traits make it suitable for a power-constrained handheld device, where sustained performance at low power matters more than peak throughput. The RTX 5070 Mobile, with its 50 W TDP and 8 GB GDDR7, is built for laptops that can feed and cool a much larger GPU.

The data shows no overlap in benchmark wins because the AMD part has no scores to compare. The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 performance, while the Steam Deck OLED GPU delivers 1.638 TFLOPS. That is an 8x difference in raw floating-point throughput. Texture rate tells a similar story: 205.2 GTexel/s versus 51.20 GTexel/s, and pixel rate is 68.40 GPixel/s versus 25.60 GPixel/s. Every throughput metric in the database favors the NVIDIA part by a wide margin.

The Verdict

The data points to a simple conclusion. The NVIDIA GeForce RTX 5070 Mobile is the faster GPU by every recorded metric, and it is the only one of the two with any benchmark scores in the database. Its average benchmark score of 29928 places it within 0.1% of the NVIDIA GeForce RTX 3070 Ti (29945), 0.5% ahead of the RTX 2080 Ti (29783), and 0.6% ahead of the AMD Radeon RX 6800 (30095, meaning the RTX 5070 Mobile trails that card by 0.6%). It sits 1.7% behind the AMD Radeon RX 6700 (30433). These are desktop-class comparisons, which indicates the RTX 5070 Mobile delivers performance in the range of previous-generation desktop flagships.

The AMD Steam Deck OLED GPU has no benchmark scores, so the database cannot confirm any performance level for it. Its hardware profile indicates a very different purpose: a 15 W part with 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The RTX 5070 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The NVIDIA part has 9x the shading units and 4.5x the ray tracing cores.

Who should pick which comes down to the workload envelope. The RTX 5070 Mobile is the choice for any application requiring high throughput, ray tracing, or tensor acceleration. The Steam Deck OLED GPU is the choice for a handheld or ultra-low-power device where 15 W is the entire power budget and 16 GB of unified LPDDR5 memory is an asset. The data cannot recommend the AMD part for performance workloads because it has no recorded scores. It can only describe its hardware configuration.

Head-to-Head Benchmarks

The RTX 5070 Mobile has nine recorded benchmark results. Its Geekbench OpenCL score is 122238, and its Geekbench Vulkan score is 116960. Passmark results include DirectX 10 at 129, DirectX 11 at 192, DirectX 12 at 93, DirectX 9 at 214, G2D at 896, G3D at 20355, and GPU compute at 8279. These scores establish the NVIDIA part as a solid mid-to-high range mobile GPU.

The largest wins for the RTX 5070 Mobile relative to its nearest rivals appear in the average benchmark score comparisons. It trails the AMD Radeon RX 6700 by 1.7%, which is the largest gap in the rival list. It also trails the AMD Radeon RX 6800 by 0.6% and the NVIDIA GeForce RTX 3070 Ti by 0.1%. It leads the RTX 2080 Ti by 0.5%. These deltas are small, meaning the RTX 5070 Mobile sits in a closely packed performance band around 30000 average score.

The Steam Deck OLED GPU has no head-to-head benchmark entries and no wins in the database. Its hardware specs show why it cannot compete on raw performance. FP32 throughput of 1.638 TFLOPS versus 13.13 TFLOPS is a 8x gap. Memory bandwidth of 176.0 GB/s versus 384.0 GB/s is a 2.2x gap. Texture rate of 51.20 GTexel/s versus 205.2 GTexel/s is a 4x gap. Pixel rate of 25.60 GPixel/s versus 68.40 GPixel/s is a 2.7x gap.

The RTX 5070 Mobile also supports Vulkan 1.4, while the Steam Deck OLED GPU supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The NVIDIA part uses PCIe 5.0 x16, while the AMD part has no bus interface listed. The NVIDIA part has 144 tensor cores, which the AMD part lacks entirely. These architectural differences reinforce the benchmark gap.
