AMD Steam Machine GPU vs NVIDIA GeForce RTX 5090 D V2 Comparison

The AMD Steam Machine GPU and NVIDIA GeForce RTX 5090 D V2 occupy completely different segments of the hardware landscape. The Steam Machine GPU is a compact console-oriented part built for a specific Valve platform, while the RTX 5090 D V2 is a full-size desktop flagship. The database contains no direct head-to-head benchmark runs between these two products, and the Steam Machine GPU has no recorded benchmark scores or rival comparisons. What follows is a comparative analysis based on the recorded specifications, the single benchmark score for the RTX 5090 D V2, and the nearest rival data available for that card.

Head-to-Head Benchmarks

The database shows no shared test results between the AMD Steam Machine GPU and the NVIDIA GeForce RTX 5090 D V2. The Steam Machine GPU has zero benchmark entries, zero wins, and zero recorded rival comparisons. Its average benchmark score is listed as zero, which indicates no measured performance data has been recorded for this product. The RTX 5090 D V2, by contrast, has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 16,504 points. That score places the card at the 59th percentile among all GPUs in the database, meaning it sits above the median but not at the absolute top of the recorded pool.

The RTX 5090 D V2’s nearest rivals in the database are tightly clustered around its score. The NVIDIA T400 averages 16,508 points, a difference of 0 percent. The AMD Radeon PRO W7500 scores 16,415, which is 0.5 percent behind. The NVIDIA RTX PRO 6000 Blackwell averages 16,408, a 0.6 percent gap. The AMD Radeon RX 5700 XT scores 16,361, trailing by 0.9 percent. These deltas are remarkably small, with the entire rival group falling within a 1 percent band of the RTX 5090 D V2’s result. The data shows that in this particular DX12 workload, the RTX 5090 D V2 is effectively tied with several much older or lower-tier cards, despite its flagship positioning.

The Steam Machine GPU has no comparable benchmark data, so no numerical win or loss can be assigned to it. The wins tally shows 0 for the AMD part and 0 for the NVIDIA part, confirming the absence of any direct measured comparison. The only quantitative anchor in the entire comparison is the RTX 5090 D V2’s 16,504-point Steel Nomad score and its four nearest-rival scores.

Where Each One Wins

Without benchmark data for the Steam Machine GPU, the analysis must rely on architectural specifications to infer where each product would likely succeed. The RTX 5090 D V2 shows overwhelming advantages in raw compute resources. It carries 21,760 shading units versus 1,792 for the Steam Machine GPU, a 12.1x difference. Its FP32 throughput is 104.8 TFLOPS compared to 17.56 TFLOPS, roughly 6x higher. The NVIDIA card also has 170 ray tracing cores and 680 tensor cores, while the AMD part has 28 ray tracing cores and no tensor cores listed. In any workload that scales with shader count, ray tracing, or tensor operations, the RTX 5090 D V2 would dominate.

Memory capacity and bandwidth also split decisively. The RTX 5090 D V2 has 24 GB of GDDR7 on a 384-bit bus, delivering 1.34 TB/s of bandwidth. The Steam Machine GPU has 8 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s. That is a 3x memory capacity advantage and a 4.65x bandwidth advantage for the NVIDIA part. For large datasets, high-resolution textures, or AI inference workloads, the RTX 5090 D V2 would hold a clear edge.

The Steam Machine GPU’s wins would come from efficiency and physical footprint. Its total board power is 110 W versus 575 W for the RTX 5090 D V2, a 5.2x lower power draw. The AMD part requires no power connectors, while the NVIDIA card needs a single 16-pin connector and a suggested power supply of 950 W. The Steam Machine GPU measures 156 mm in length, 152 mm in height, and 162 mm in width, while the RTX 5090 D V2 spans 304 mm in length, 137 mm in height, and 48 mm in width. The AMD part is substantially shorter in length and far less power-hungry, which suits compact console enclosures. The NVIDIA card is dual-slot and would require a full desktop chassis.

The transistor data also tells a story of design philosophy. The Steam Machine GPU uses 13,300 million transistors on a 204 mm² die, yielding a density of 65.2 million transistors per square millimeter. The RTX 5090 D V2 packs 92,200 million transistors onto a 750 mm² die, with a density of 122.9 million per square millimeter. The NVIDIA chip is nearly 7x larger in die area and carries 6.9x more transistors, reflecting a much more complex architecture.

The Verdict

The data supports a clear split. The RTX 5090 D V2 is the superior performer by every recorded compute metric. It has 12.1x more shading units, 6x higher FP32 throughput, 3x more memory, and 4.65x more bandwidth. Its single benchmark score of 16,504 in 3DMark Steel Nomad DX12 places it at the 59th percentile, and its nearest rivals all sit within 1 percent of that score, indicating consistent performance in that workload. The Steam Machine GPU has no recorded benchmark scores, so no performance claim can be made for it from the database.

The Steam Machine GPU wins on power efficiency and size. At 110 W with no external power connectors, it operates at roughly one-fifth the power draw of the RTX 5090 D V2’s 575 W. Its 156 mm length makes it suitable for small form factor systems, while the NVIDIA card’s 304 mm length requires a much larger chassis. The AMD part also runs on a 6 nm process node from TSMC, while the NVIDIA card uses a 5 nm node, though both come from the same foundry.

Who should pick which comes down to the use case. The RTX 5090 D V2 is the choice for desktop workloads requiring maximum compute, large memory pools, or tensor core acceleration. The Steam Machine GPU is the choice for a fixed console platform where power draw and physical space are constrained. The database does not provide any evidence that the Steam Machine GPU can compete with the RTX 5090 D V2 in raw performance, nor does it provide any evidence that the RTX 5090 D V2 can match the Steam Machine GPU’s efficiency profile. The recorded data simply confirms that these are two different products for two different environments.
