AMD Steam Machine GPU vs NVIDIA GeForce RTX 4060 Mobile Comparison

The AMD Steam Machine GPU and the NVIDIA GeForce RTX 4060 Mobile represent two distinct approaches to mobile and console-class graphics. The Steam Machine GPU, built on RDNA 3.0, is a console-specific part with a 50th percentile ranking among all GPUs. The RTX 4060 Mobile, an Ada Lovelace laptop part, sits higher at the 67th percentile. The database records no direct head-to-head benchmark scores between them, but their architectural characteristics and the RTX 4060 Mobile’s measured performance provide a basis for comparison.

Head-to-Head Benchmarks

A direct benchmark comparison is not available in the database, as the head-to-head array is empty. However, the RTX 4060 Mobile has a recorded average benchmark score of 22,729 across its tests, while the Steam Machine GPU has an average score of 0, indicating no completed benchmark runs. This absence of data means the Steam Machine GPU cannot be placed relative to the RTX 4060 Mobile through direct testing.

The RTX 4060 Mobile’s individual benchmark results show a clear profile. Its Passmark G3D score is 17,469, while its Geekbench OpenCL score is 89,420 and its Geekbench Vulkan score is 89,569. Compute performance is measured at 6,816 in Passmark GPU Compute. The Steam Machine GPU has no comparable scores listed.

The nearest rivals for the RTX 4060 Mobile provide context. The NVIDIA GeForce RTX 2080 scores 22,895, which is 0.7% higher than the RTX 4060 Mobile. The AMD Radeon RX 7700 XT scores 22,549, placing it 0.8% lower. The Intel Arc B580 scores 23,021, which is 1.3% higher. The NVIDIA GeForce RTX 5060 Mobile scores 22,435, sitting 1.3% lower. This places the RTX 4060 Mobile within a tight cluster of desktop and mobile parts, all within roughly 1.3% of each other in average score.

Where Each One Wins

The RTX 4060 Mobile wins in raw shader throughput metrics from the specification data. It has 3,072 shading units compared to the Steam Machine GPU’s 1,792. This higher count suggests a potential advantage in shader-heavy workloads, though the Steam Machine GPU compensates with higher clock speeds. The Steam Machine GPU boosts to 2,450 MHz, while the RTX 4060 Mobile boosts to 1,890 MHz. The Steam Machine GPU also has a higher base clock at 1,720 MHz versus 1,545 MHz.

The Steam Machine GPU wins in memory bandwidth. It delivers 288.0 GB/s compared to the RTX 4060 Mobile’s 256.0 GB/s, a 12.5% advantage. Both use 8 GB of GDDR6 memory on a 128-bit bus, but the Steam Machine GPU runs its memory at 2,250 MHz (18 Gbps effective) versus the RTX 4060 Mobile’s 2,000 MHz (16 Gbps effective). This bandwidth difference matters in texture-heavy scenes and high-resolution rendering.

Rasterization rates favor the Steam Machine GPU. Its pixel rate is 156.8 GPixel/s versus 90.72 GPixel/s for the RTX 4060 Mobile, and its texture rate is 274.4 GTexel/s versus 181.4 GTexel/s. The Steam Machine GPU has 64 ROPs and 112 TMUs, while the RTX 4060 Mobile has 48 ROPs and 96 TMUs. Compute throughput also favors the Steam Machine GPU, with 17.56 TFLOPS FP32 performance compared to the RTX 4060 Mobile’s 11.61 TFLOPS.

The RTX 4060 Mobile wins in ray tracing resources. It has 24 RT cores and 96 tensor cores, while the Steam Machine GPU has 28 RT cores and no tensor cores. The RTX 4060 Mobile’s tensor cores enable DLSS and other AI-accelerated features, which the Steam Machine GPU lacks. This creates a functional split: the Steam Machine GPU leads in traditional rasterization and raw compute, while the RTX 4060 Mobile leads in ray tracing and AI-assisted rendering.

The Verdict

The data indicates the Steam Machine GPU is built for raw throughput. Its higher clock speeds, wider ROP and TMU counts, and greater memory bandwidth position it as a rasterization-focused part. The RTX 4060 Mobile, with its tensor cores and higher shading unit count, is designed for feature-rich rendering pipelines that leverage AI and ray tracing.

For users prioritizing traditional rasterization performance and memory bandwidth, the Steam Machine GPU’s specifications show a clear advantage. Its pixel rate of 156.8 GPixel/s and texture rate of 274.4 GTexel/s exceed the RTX 4060 Mobile’s corresponding figures by substantial margins. Compute workloads also favor the Steam Machine GPU, with 17.56 TFLOPS FP32 versus 11.61 TFLOPS.

For users needing ray tracing, DLSS, or other AI-based features, the RTX 4060 Mobile is the only option with tensor cores. Its 96 tensor cores enable these capabilities, which the Steam Machine GPU cannot match. The RTX 4060 Mobile also holds a higher percentile ranking at 67 versus 50, indicating stronger overall performance relative to the broader GPU market.

The RTX 4060 Mobile’s benchmark data shows it performs in line with desktop GPUs like the RTX 2080 and RX 7700 XT, both within 1% of its average score. The Steam Machine GPU has no recorded benchmarks, so its real-world performance cannot be confirmed from the database. Its specifications suggest higher rasterization throughput, but without measured scores, that remains theoretical.
