AMD Steam Machine GPU vs NVIDIA GeForce RTX 4070 SUPER Comparison

The Verdict

The recorded data places the NVIDIA GeForce RTX 4070 SUPER in a clearly higher performance tier. Its average benchmark score of 43223 puts it at the 83rd percentile among all GPUs, while the AMD Steam Machine GPU sits at the 50th percentile with an average benchmark score of 0 in the database. The RTX 4070 SUPER outperforms the nearest rivals in its own bracket, with the closest competitor, the NVIDIA Quadro M6000 24 GB, scoring 43262, a delta of only 0.1% behind. The gap between the two cards in this comparison is substantial across every measured dimension, from raw throughput to memory bandwidth.

The AMD Steam Machine GPU, despite its lower absolute scores, is designed for a specific console context. It operates at a 110 W TDP with no power connectors, drawing power entirely through the slot, which makes it suitable for compact, integrated systems. The RTX 4070 SUPER, by contrast, requires a 16-pin connector and a 550 W suggested PSU, indicating a desktop-oriented design with higher power headroom. The data shows that the RTX 4070 SUPER is the choice for users who prioritize maximum performance, while the AMD part serves a niche where power draw and physical footprint are the primary constraints.

Architecture Differences

The two GPUs diverge fundamentally in their underlying architectures. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It is fabricated on a 6 nm process at TSMC, housing 13,300 million transistors on a 204 mm² die, resulting in a transistor density of 65.2 million per mm². The NVIDIA GeForce RTX 4070 SUPER uses the AD104 chip based on Ada Lovelace architecture, produced on a 5 nm process, also at TSMC. It contains 35,800 million transistors across a 294 mm² die, yielding a transistor density of 121.8 million per mm², nearly double that of the AMD chip.

Core configurations differ sharply. The AMD GPU has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The NVIDIA GPU has 7168 shading units, 224 TMUs, 80 ROPs, 56 RT cores, and 224 tensor cores. The NVIDIA part also includes tensor cores, which are absent from the AMD specification. These architectural choices reflect different priorities: NVIDIA allocates more silicon to compute and AI acceleration, while AMD focuses on a leaner design suitable for a console environment.

The memory subsystems also differ. The AMD card uses 8 GB of GDDR6 on a 128 bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA card uses 12 GB of GDDR6X on a 192 bit bus, delivering 504.2 GB/s. The process node advantage for NVIDIA, combined with the higher transistor count, explains much of the performance delta. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, as does the NVIDIA part, so API compatibility is not a differentiator.

Head-to-Head Benchmarks

The RTX 4070 SUPER has a rich set of benchmark results in the database, while the AMD Steam Machine GPU has no recorded benchmark scores. The NVIDIA card's average benchmark score of 43223 places it far above the 50th percentile baseline occupied by the AMD part. In specific tests, the RTX 4070 SUPER achieves a 3DMark Steel Nomad DX12 score of 4627, a Geekbench OpenCL score of 172795, and a Geekbench Vulkan score of 205624. Passmark results show a G3D score of 29995 and a GPU compute score of 17108. These figures confirm strong performance across both gaming and compute workloads.

The nearest rivals to the RTX 4070 SUPER, as recorded in the database, are all NVIDIA parts. The Quadro M6000 24 GB scores 43262, a delta of -0.1%, placing it statistically tied with the RTX 4070 SUPER. The GeForce RTX 5050 Mobile scores 43268, also a -0.1% delta. The Quadro M6000 scores 43301, a -0.2% delta. The GeForce RTX 4090 Mobile scores 43667, a -1% delta, meaning the RTX 4070 SUPER is about 1% behind that mobile flagship. These tight margins indicate that the RTX 4070 SUPER delivers desktop-class performance comparable to high-end mobile parts and professional workstation cards.

The AMD Steam Machine GPU, with an average benchmark score of 0 and no entries in its benchmark array, cannot be directly compared test by test. The data shows that its strengths lie elsewhere, specifically in power efficiency and physical integration. Its FP32 throughput of 17.56 TFLOPS is exactly half of the NVIDIA card's 35.48 TFLOPS, a clear indicator of the compute gap. Pixel rate and texture rate follow the same pattern: the AMD card delivers 156.8 GPixel/s and 274.4 GTexel/s, while the NVIDIA card delivers 198.0 GPixel/s and 554.4 GTexel/s. The NVIDIA part has a 26% advantage in pixel throughput and a 102% advantage in texture throughput, based on the recorded numbers.

Specification Differences

The two cards differ in nearly every specification field. The AMD Steam Machine GPU has a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. The NVIDIA GeForce RTX 4070 SUPER has a base clock of 1980 MHz and a boost clock of 2475 MHz, with no game clock listed. Memory clocks also differ: the AMD card runs at 2250 MHz with 18 Gbps effective, while the NVIDIA card runs at 1313 MHz with 21 Gbps effective. The higher effective memory speed on the NVIDIA card, combined with the wider 192 bit bus, produces the 504.2 GB/s bandwidth figure.

Power requirements are a major differentiator. The AMD card has a TDP of 110 W and uses no power connectors, while the NVIDIA card has a TDP of 220 W and requires a single 16-pin connector. The suggested PSU for the NVIDIA card is 550 W. Physical dimensions also contrast sharply: the AMD card measures 156 mm in length, 152 mm in height, and 162 mm in width, making it nearly square and compact. The NVIDIA card measures 267 mm in length, 112 mm in height, and 42 mm in width, a standard dual-slot desktop layout. The AMD card has no listed slot width, while the NVIDIA card is dual-slot.

Display outputs differ as well. The AMD card offers one HDMI 2.1 and one DisplayPort 2.1. The NVIDIA card offers one HDMI 2.1 and three DisplayPort 1.4a outputs. The bus interface is not specified for the AMD card, while the NVIDIA card uses PCIe 4.0 x16. Production status also differs: the AMD card is listed as active, while the NVIDIA card is end-of-life. The release dates place the AMD card in 2026, while the NVIDIA card launched in 2024. The NVIDIA card has a predecessor in the GeForce 30 series and a successor in the GeForce 50 series, while the AMD card has neither listed.
