AMD Steam Machine GPU vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Steam Machine GPU and the NVIDIA GeForce RTX 5070 Ti Mobile. The AMD part has no benchmark scores listed, while the NVIDIA part has nine recorded tests. The absence of overlapping measurements means a direct score-for-score comparison cannot be constructed from the database. What the data does show is where the NVIDIA part stands on its own, and where the AMD part sits by specification and percentile ranking.

The NVIDIA GeForce RTX 5070 Ti Mobile posts an average benchmark score of 35435, placing it at the 80th percentile of all GPUs in the database. Its nearest rivals include the NVIDIA Quadro GV100 at 35520 (0.2% behind the 5070 Ti Mobile), the AMD Radeon Pro Duo at 35860 (1.2% behind), the NVIDIA A2 at 34690 (2.1% ahead of the A2), and the NVIDIA T1000 at 36289 (2.4% behind the 5070 Ti Mobile). These deltas are tight, all within 2.4 percentage points, indicating the 5070 Ti Mobile sits in a densely packed performance cluster where small variations separate competitors.

Breaking down the NVIDIA part's individual benchmark scores, the Geekbench OpenCL result of 143870 and Vulkan result of 139213 show strong compute and graphics API performance. The PassMark suite reveals a different picture: DirectX 10 scores 151, DirectX 11 scores 237, DirectX 12 scores 102, and DirectX 9 scores 259. The PassMark G3D score of 24004 and GPU compute score of 10101 add context, while the 2D score of 981 indicates modest 2D throughput. The wide gap between the Geekbench scores and the low PassMark DirectX scores suggests the 5070 Ti Mobile excels in modern compute-heavy workloads but shows weaker results in legacy DirectX tests.

The AMD Steam Machine GPU carries a percentile rank of 50, meaning half of all GPUs in the database score higher and half score lower. With no benchmark entries, its average score is recorded as zero, which cannot be interpreted as a performance result but rather as missing data. The specification sheet, however, provides a basis for qualitative comparison: the AMD part's FP32 throughput of 17.56 TFLOPS is marginally higher than the NVIDIA part's 17.04 TFLOPS, a difference of about 3%. The NVIDIA part's pixel rate of 115.8 GPixel/s is lower than the AMD part's 156.8 GPixel/s, while the texture rates are close: 274.4 GTexel/s for AMD versus 266.2 GTexel/s for NVIDIA.

Architecture Differences

The two GPUs come from different architectural generations. The AMD Steam Machine GPU uses the RDNA 3.0 architecture on a 6 nm TSMC process, with the Navi 33 chip and the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on a 5 nm TSMC process, with the GB205 chip and a GeForce 50 Mobile generation designation. The process difference of 6 nm versus 5 nm is small but contributes to transistor density differences: the AMD chip packs 13,300 million transistors on a 204 mm² die, yielding 65.2 million transistors per square millimeter, while the NVIDIA chip packs 31,100 million transistors on a 263 mm² die, yielding 118.3 million per square millimeter. The NVIDIA die is larger and nearly 2.5 times denser in transistor packing.

Core counts differ substantially. The AMD part has 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The NVIDIA part has 5888 shading units, 184 TMUs, 80 ROPs, 46 ray tracing cores, and adds 184 tensor cores. The shading unit advantage for NVIDIA is roughly 3.3 times the AMD count, yet the FP32 throughput is nearly identical at 17.04 TFLOPS versus 17.56 TFLOPS. This indicates the AMD architecture extracts higher per-shader efficiency, or the clock speeds compensate. The AMD part boosts to 2450 MHz with a game clock of 2250 MHz and a base of 1720 MHz, while the NVIDIA part has a much lower base of 847 MHz and boost of 1447 MHz. Lower clocks on NVIDIA explain how a larger shader count arrives at similar FP32.

Memory architecture diverges clearly. The AMD Steam Machine GPU uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA part uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s, more than double the bandwidth. The NVIDIA memory operates at 1750 MHz with 28 Gbps effective, while the AMD memory runs at 2250 MHz with 18 Gbps effective. The wider bus and newer memory type give NVIDIA a decisive bandwidth advantage, which matters for high-resolution textures and compute workloads. The AMD part's power draw is 110 W, while the NVIDIA part draws only 60 W, making the NVIDIA part nearly twice as power-efficient per watt by this metric, despite its higher memory bandwidth and larger transistor count.

Where Each One Wins

The AMD Steam Machine GPU wins in raw pixel throughput. Its pixel rate of 156.8 GPixel/s exceeds the NVIDIA part's 115.8 GPixel/s by roughly 35%. This suggests the AMD part can fill framebuffers faster in scenarios where ROP throughput is the bottleneck, such as lower-resolution rendering with heavy overdraw. Texture rate also favors AMD slightly, 274.4 GTexel/s versus 266.2 GTexel/s, a margin of about 3%. For pure rasterization at lower resolutions, the AMD part has a measurable edge in these two specific throughput metrics.

The NVIDIA GeForce RTX 5070 Ti Mobile wins in memory bandwidth by a wide margin: 672.0 GB/s versus 288.0 GB/s, which is 133% higher. This advantage shows up in memory-intensive workloads like 4K texture streaming, ray tracing acceleration, and compute tasks that repeatedly access large data sets. The NVIDIA part also has more memory capacity at 12 GB versus 8 GB, a 50% increase, which allows larger working sets without spillover. The tensor core count of 184 on NVIDIA versus none on AMD gives NVIDIA a clear edge in AI inference and machine learning tasks, assuming software can utilize tensor cores. The NVIDIA part's lower power draw of 60 W versus 110 W means it delivers its performance at nearly half the power budget, which is relevant for mobile or thermally constrained designs.

The recorded benchmarks for NVIDIA show strong compute performance: Geekbench OpenCL at 143870 and Vulkan at 139213. The PassMark G3D score of 24004 places it in the 80th percentile. The AMD part has no recorded benchmarks, so its real-world wins cannot be confirmed from the database. What the data shows is that the AMD part wins on paper in pixel rate and texture rate, while the NVIDIA part wins on bandwidth, capacity, tensor cores, power efficiency, and has actual benchmark scores to demonstrate its performance tier.

The Verdict

The database shows two GPUs built for different roles. The AMD Steam Machine GPU, with its 110 W TDP, 6 nm process, and 8 GB GDDR6, targets a console-style fixed hardware environment. Its strengths lie in pixel rate (156.8 GPixel/s) and texture rate (274.4 GTexel/s), both ahead of the NVIDIA part. The NVIDIA GeForce RTX 5070 Ti Mobile, with its 60 W TDP, 5 nm process, and 12 GB GDDR7, targets mobile systems where power efficiency and memory bandwidth matter. Its bandwidth of 672.0 GB/s is more than double the AMD part, and its 184 tensor cores add AI capability the AMD part lacks.

The recorded benchmark data only covers the NVIDIA part, which sits at the 80th percentile with an average score of 35435. The AMD part has no benchmark scores, so its actual performance cannot be verified from the database. Based on specifications alone, the AMD part wins on pixel and texture throughput, while the NVIDIA part wins on bandwidth, capacity, tensor cores, and power efficiency. Users prioritizing raw ROP throughput at lower resolutions might favor the AMD part. Users needing memory-heavy workloads, AI features, or lower power consumption should favor the NVIDIA part. The NVIDIA part's release date of 2025-02-28 predates the AMD part's 2026-06-28, meaning the AMD part is a newer design entering the market later. The data does not support a universal winner, as each part leads in distinct specification categories.
