Q: What are the power consumption figures?

A: The AMD Steam Deck OLED GPU has a TDP of 15 W, while the NVIDIA GeForce RTX 5070 Ti SUPER has a TDP of 350 W. This represents a substantial difference in power draw.

Q: What benchmark data exists for these GPUs?

A: The database contains no benchmark entries for the AMD GPU, resulting in an average benchmark score of 0 and a percentile of 50 among all GPUs. The NVIDIA GPU has one recorded benchmark result: 6269.5 in 3DMark Steel Nomad DX12, with an average score of 6270 and a percentile of 36.

Q: What are the nearest rivals for the NVIDIA GPU based on recorded scores?

A: The nearest rivals for the NVIDIA GeForce RTX 5070 Ti SUPER are the NVIDIA GeForce RTX 4070 Ti SUPER AD102 with an identical average score of 6270 (0% delta), the NVIDIA Quadro K620 at 6282 (-0.2%), the AMD FirePro W600 at 6223 (+0.8%), and the AMD Radeon R7 M350 at 6327 (-0.9%).

Architecture Differences

The two GPUs represent fundamentally different design philosophies and market positions. The AMD Steam Deck OLED GPU, built around the Sephiroth chip, uses RDNA 2.0 architecture and is classified as a Console GPU designed for Valve's handheld device. The NVIDIA GeForce RTX 5070 Ti SUPER uses the GB203 chip with Blackwell 2.0 architecture and belongs to the GeForce 50-series desktop lineup.

Process technology separates the pair clearly. The AMD chip is fabricated on a 6 nm process, while the NVIDIA chip uses a 5 nm process. Both come from TSMC, but the density figures show the NVIDIA design packs significantly more circuitry: 120.6M transistors per mm² versus 18.3M for AMD. Total transistor counts are 45,600 million for NVIDIA against 2,400 million for AMD, a 19-fold difference on a die that is roughly 2.9 times larger (378 mm² versus 131 mm²).

Compute resource allocation differs dramatically. The AMD GPU has 512 shading units, 32 texture mapping units, 16 raster operation units, and 8 ray tracing cores. The NVIDIA GPU has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. NVIDIA also lists tensor cores where AMD has none, indicating support for AI-accelerated workloads that the AMD part lacks entirely.

Clock behavior also separates them. AMD runs at a 1000 MHz base and 1600 MHz boost, while NVIDIA operates at 2295 MHz base and 2452 MHz boost. The NVIDIA memory clock is 1750 MHz with 28 Gbps effective speed, compared to AMD's 1375 MHz with 11 Gbps effective speed. Memory type differs as well: LPDDR5 on the AMD side versus GDDR7 on the NVIDIA side.

API support shows partial overlap. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. NVIDIA adds Vulkan 1.4 support while AMD lists Vulkan 1.3. The NVIDIA card uses PCIe 5.0 x16 as its bus interface, while the AMD card has no listed bus interface. Display outputs also differ: AMD provides a single USB Type-C connector, while NVIDIA offers 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between these two GPUs. The wins tally shows 0 for each side. This means any performance comparison must rely on the limited recorded data and the specification differences.

The only benchmark score present in the database belongs to the NVIDIA GeForce RTX 5070 Ti SUPER: 6269.5 in 3DMark Steel Nomad DX12, with an average score of 6270. Its percentile among all GPUs is 36, which places it below the median performance tier in the database. The AMD Steam Deck OLED GPU has no recorded benchmarks, an average score of 0, and a percentile of 50.

The nearest rival data for NVIDIA provides context for its benchmark position. The RTX 4070 Ti SUPER AD102 scores identically at 6270 with a 0% delta, indicating the RTX 5070 Ti SUPER delivers performance on par with that previous-generation card. The Quadro K620 scores 6282, 0.2% higher, while the FirePro W600 scores 6223, 0.8% lower. The Radeon R7 M350 scores 6327, which is 0.9% higher. These deltas are minimal, suggesting the RTX 5070 Ti SUPER sits in a tightly clustered performance band around the 6270 mark.

Without AMD benchmark data, no quantitative comparison is possible. The database shows no head-to-head tests, and the AMD GPU has zero recorded scores. Any statement about relative performance must therefore derive from architectural specifications rather than measured results.

The Verdict

The recorded data supports only a limited verdict. The NVIDIA GeForce RTX 5070 Ti SUPER has a confirmed benchmark score of 6269.5 in 3DMark Steel Nomad DX12, placing it at the 36th percentile among all GPUs. Its nearest rivals cluster within 0.9% of that score, indicating consistent performance around that level.

The AMD Steam Deck OLED GPU has no recorded benchmark scores. Its percentile of 50 is a default value, not a measured result. The database cannot confirm any performance level for this GPU through direct testing.

Selection between the two should follow the data available. For users who require a desktop GPU with confirmed DirectX 12 benchmark performance, the NVIDIA card has measurable results. The AMD card serves a different role as a console GPU with a 15 W TDP, designed for portable operation rather than high-throughput desktop workloads. The specification gap in shading units (512 versus 8,960), texture rate (51.20 GTexel/s versus 686.6 GTexel/s), and pixel rate (25.60 GPixel/s versus 235.4 GPixel/s) indicates the NVIDIA part is built for substantially higher output.

Where Each One Wins

The AMD Steam Deck OLED GPU demonstrates advantages in power efficiency. Its 15 W TDP is dramatically lower than the NVIDIA's 350 W, making it suitable for battery-powered handheld operation. The compact dimensions (298 mm length, 117 mm height, 49 mm width) and single USB Type-C display output align with a portable form factor. The absence of a power connector requirement and the lack of a slot width specification further indicate an integrated, low-power design.

The NVIDIA GeForce RTX 5070 Ti SUPER wins decisively on raw compute specifications. Its FP32 throughput of 43.94 TFLOPS is roughly 27 times higher than the AMD's 1.638 TFLOPS. Texture rate of 686.6 GTexel/s exceeds AMD's 51.20 GTexel/s by a factor of 13.4. Pixel rate of 235.4 GPixel/s surpasses AMD's 25.60 GPixel/s by roughly 9.2 times. Memory bandwidth of 896.0 GB/s is over five times AMD's 176.0 GB/s.

The NVIDIA card also wins on feature set. It includes 280 tensor cores for AI workloads, which the AMD part lacks entirely. Its 70 RT cores versus 8 provide more ray tracing capacity. Vulkan 1.4 support extends beyond AMD's Vulkan 1.3. The 256-bit memory bus and GDDR7 memory type support higher throughput than the 128-bit LPDDR5 configuration.

In benchmark terms, the NVIDIA card has a recorded 3DMark Steel Nomad DX12 score of 6269.5. The AMD card has no recorded scores, so the database cannot confirm any benchmark win for it. The NVIDIA card's percentile of 36 versus AMD's default 50 does not reflect measured superiority for AMD; it reflects missing data.

The use-case split follows the specifications. The AMD card serves handheld or low-power console applications where the 15 W TDP and compact footprint are essential. The NVIDIA card serves desktop gaming and compute workloads where the 350 W TDP, dual-slot cooler, and PCIe 5.0 x16 interface can be accommodated, and where the 43.94 TFLOPS FP32 throughput and 280 tensor cores provide substantial processing capability.
