AMD Steam Machine GPU vs NVIDIA GeForce RTX 4070 Ti SUPER AD102 Comparison

Where Each One Wins

The recorded data presents a stark asymmetry in benchmark coverage. The AMD Steam Machine GPU has no entry in the benchmarks field, yielding zero aggregate scores and zero recorded wins. The NVIDIA GeForce RTX 4070 Ti SUPER AD102, by contrast, has a single 3DMark Steel Nomad DX12 result of 6269.5 points. This places the NVIDIA part at the 36th percentile among all GPUs in the database, with an average benchmark score of 6270. In every measurable category, the NVIDIA card holds the advantage, as the AMD part has no recorded performance data to contest those figures.

The use-case split is therefore unambiguous: the Steam Machine GPU is a console-oriented part with no validated benchmark results, while the RTX 4070 Ti SUPER AD102 is a desktop GPU with a confirmed DirectX 12 workload score. For tasks that stress rasterization and modern API features, the NVIDIA card delivers a quantifiable result. For any workload on the AMD part, the database contains no evidence of performance, which means no win condition can be assigned to it.

Architecture Differences

The two GPUs diverge fundamentally in their underlying designs. The AMD Steam Machine GPU uses the Navi 33 chip, built on RDNA 3.0 architecture with the codename "Hotpink Bonefish." It is manufactured on a 6 nm process at TSMC, housing 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The NVIDIA GeForce RTX 4070 Ti SUPER AD102 uses the AD102 chip, built on Ada Lovelace architecture. It is manufactured on a 5 nm process at TSMC, housing 76,300 million transistors on a 609 mm² die, yielding a transistor density of 125.3 million per square millimeter.

The NVIDIA chip nearly quadruples the transistor count and triples the die area, while also achieving roughly double the transistor density. These structural differences cascade into every compute metric. The AMD part has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores, with no tensor cores listed. The NVIDIA part has 8448 shading units, 264 TMUs, 96 ROPs, 66 ray tracing cores, and 264 tensor cores. The NVIDIA GPU also supports PCIe 4.0 x16 as its bus interface, while the AMD part has no bus interface specified in the database.

Specification Differences

The two cards differ across nearly every specification field in the database. Clock speeds: the AMD part runs at a 1720 MHz base, 2450 MHz boost, and 2250 MHz game clock, with memory at 2250 MHz (18 Gbps effective). The NVIDIA part runs at a 2340 MHz base and 2610 MHz boost, with no game clock listed, and memory at 1313 MHz (21 Gbps effective). Both have identical API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Memory capacity and bandwidth are major separators: 8 GB versus 16 GB, GDDR6 versus GDDR6X, 128-bit versus 256-bit bus, and 288.0 GB/s versus 672.3 GB/s. Compute rates follow the same pattern. The AMD card delivers 17.56 TFLOPS for both FP32 and FP16 (1:1). The NVIDIA card delivers 44.10 TFLOPS for both FP32 and FP16 (1:1). Pixel rate is 156.8 GPixel/s versus 250.6 GPixel/s, and texture rate is 274.4 GTexel/s versus 689.0 GTexel/s.

Physical dimensions differ substantially. The AMD card measures 156 mm in length, 152 mm in height, and 162 mm in width. The NVIDIA card measures 310 mm in length, 140 mm in height, and 61 mm in width, and is a triple-slot design. The AMD card has no listed slot width. The NVIDIA card also carries a launch MSRP of 799 USD, while the AMD part has no MSRP recorded. The NVIDIA card has a predecessor in the GeForce 30 series and a successor in the GeForce 50 series, while the AMD card lists none.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The only recorded benchmark belongs to the NVIDIA GeForce RTX 4070 Ti SUPER AD102: a 3DMark Steel Nomad DX12 score of 6269.5 points. This single result anchors the NVIDIA card's average benchmark score at 6270 and its percentile ranking at 36 among all GPUs.

The AMD Steam Machine GPU has no benchmark entries, no average score, and no percentile ranking beyond its position at 50 in the percentileVsAllGpus field, which appears to be a default placeholder rather than a measured result. With zero wins attributed to the AMD part and zero wins attributed to the NVIDIA part in the head-to-head field, the recorded data offers no direct comparison points.

Rival analysis for the NVIDIA card provides context. The RTX 4070 Ti SUPER AD102 scores identically to the NVIDIA GeForce RTX 5070 Ti SUPER, with a delta of 0 percent. It trails the NVIDIA Quadro K620 by 0.2 percent (6282 versus 6270) and the AMD Radeon R7 M350 by 0.9 percent (6327 versus 6270). It leads the AMD FirePro W600 by 0.8 percent (6223 versus 6270). These are small margins, indicating that the RTX 4070 Ti SUPER AD102 sits in a tightly contested performance band among these specific rivals, despite its 36th percentile overall ranking.

The absence of AMD benchmark data means the Steam Machine GPU cannot be positioned against any rival, including the NVIDIA card in this comparison. Every measurable advantage, from memory bandwidth to shading units to fill rates, belongs to the NVIDIA part, but the database cannot confirm a single workload result for the AMD card. The comparison is therefore one-sided in terms of evidence, with the NVIDIA card standing as the only validated performer in this pairing.
