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

Head-to-Head Benchmarks

The recorded database contains comprehensive benchmark data only for the NVIDIA GeForce RTX 5070 Ti Mobile, with no corresponding scores for the AMD Steam Deck OLED GPU. This asymmetry makes a direct score-by-score comparison impossible. However, the available data for the NVIDIA part establishes a clear performance tier that the AMD processor cannot approach.

The RTX 5070 Ti Mobile delivers an average benchmark score of 35,435 across all recorded tests, placing it in the 80th percentile of all GPUs in the database. Its nearest rivals include the NVIDIA Quadro GV100 with an average score of 35,520, a delta of -0.2%, and the AMD Radeon Pro Duo at 35,860, which sits 1.2% ahead. The NVIDIA A2 trails by 2.1% with 34,690, while the NVIDIA T1000 leads by 2.4% with 36,289. These narrow margins indicate the RTX 5070 Ti Mobile clusters tightly with high-end workstation-class parts.

In compute-oriented workloads, the Geekbench OpenCL score reaches 143,870, while the Vulkan test records 139,213. The Passmark G3D score of 24,004 and GPU compute score of 10,101 further substantiate the part's capability. The Steam Deck OLED GPU, by contrast, has no recorded benchmark scores in the database, and its percentile ranking stands at 50, which reflects the median position of all GPUs but carries no measured performance data of its own.

The RTX 5070 Ti Mobile shows a mixed pattern across legacy DirectX tests. Passmark DirectX 9 scores 259, DirectX 11 scores 237, DirectX 10 scores 151, and DirectX 12 scores 102. The 2D graphics score of 981 is notably higher than the 3D score, which reflects the architecture's allocation of resources. The absence of any benchmark entries for the Steam Deck OLED GPU means the database cannot quantify how far apart these two parts actually are in raw throughput.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The AMD Steam Deck OLED GPU uses the Sephiroth chip built on RDNA 2.0 architecture, fabricated on a 6 nm TSMC process. The chip contains 2,400 million transistors on a 131 mm² die, yielding a transistor density of 18.3 million per square millimeter. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0 architecture, also from TSMC but on a 5 nm node. That die measures 263 mm² and packs 31,100 million transistors, producing a density of 118.3 million per square millimeter.

The transistor count difference is staggering: 31,100 million versus 2,400 million, a factor of nearly 13. The process node advantage of 5 nm over 6 nm allows tighter packing, but the die size difference of 263 mm² versus 131 mm² also contributes substantially. The Steam Deck OLED GPU is a console-class part designed for a fixed, power-constrained handheld, while the RTX 5070 Ti Mobile is a full mobile discrete GPU.

Shader resources diverge sharply. The AMD part has 512 shading units, 32 texture mapping units, and 16 ROPs. The NVIDIA part has 5,888 shading units, 184 TMUs, and 80 ROPs. Ray tracing cores number 8 on the AMD side versus 46 on the NVIDIA side. The NVIDIA part also integrates 184 tensor cores, while the AMD part has none listed. These structural differences translate directly into the compute rates: the AMD GPU delivers 1.638 TFLOPS FP32 and 3.277 TFLOPS FP16 (2:1 ratio), while the NVIDIA GPU delivers 17.04 TFLOPS in both FP32 and FP16 (1:1 ratio), a factor of 10.4 in single-precision throughput.

Memory architectures differ in both type and configuration. The Steam Deck OLED GPU uses 16 GB of LPDDR5 on a 128-bit bus, with memory clocked at 1,375 MHz and 11 Gbps effective, producing 176.0 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, with memory at 1,750 MHz and 28 Gbps effective, yielding 672.0 GB/s. That is 3.8 times the bandwidth despite 4 GB less capacity.

The API support shows one notable divergence. Both parts support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The NVIDIA part supports Vulkan 1.4, while the AMD part supports Vulkan 1.3. The NVIDIA part uses a PCIe 5.0 x16 bus interface, whereas the AMD part lists no bus interface at all. Display outputs also differ: the Steam Deck OLED GPU has one USB Type-C output, while the RTX 5070 Ti Mobile is described as portable device dependent.

Where Each One Wins

The RTX 5070 Ti Mobile wins decisively in every measurable compute category. Its pixel rate of 115.8 GPixel/s compares to 25.60 GPixel/s for the Steam Deck OLED GPU, a 4.5 times advantage. Texture rate stands at 266.2 GTexel/s versus 51.20 GTexel/s, a 5.2 times advantage. FP32 throughput at 17.04 TFLOPS versus 1.638 TFLOPS represents a 10.4 times advantage, and FP16 output at 17.04 TFLOPS versus 3.277 TFLOPS represents a 5.2 times advantage.

The NVIDIA part also wins on memory bandwidth with 672.0 GB/s versus 176.0 GB/s. The GDDR7 memory type offers higher effective data rates of 28 Gbps versus 11 Gbps. The 192-bit bus width exceeds the 128-bit bus width, and the 80 ROPs versus 16 ROPs dictates the pixel fill rate advantage.

The Steam Deck OLED GPU holds advantages in specific areas that matter for its intended use case. It has more memory capacity at 16 GB versus 12 GB. Its power draw is far lower at 15 W versus 60 W, which is critical for a handheld device. The physical dimensions are compact at 298 mm by 117 mm by 49 mm, while the NVIDIA part has no recorded dimensions, reflecting its integration into a laptop motherboard as an IGP (integrated graphics processor) with no power connectors.

The AMD part also uses LPDDR5 memory, which is more power-efficient than GDDR7, and the 6 nm process node, while larger than 5 nm, still represents a modern fabrication method. The Vulkan 1.3 support is one version behind the NVIDIA part's Vulkan 1.4, but both support the same DirectX feature level.

The clock speeds show a counterintuitive pattern. The AMD part has higher base and boost clocks (1000 MHz / 1600 MHz versus 847 MHz / 1447 MHz), but the NVIDIA part achieves far higher throughput due to its massive shader count. The 5,888 shading units at 1,447 MHz produce 17.04 TFLOPS, while 512 shading units at 1,600 MHz produce only 1.638 TFLOPS.

The release dates are separated by roughly 15 months, with the Steam Deck OLED GPU launching on November 8, 2023, and the RTX 5070 Ti Mobile launching on February 28, 2025. Both parts remain in active production.
