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

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Steam Machine GPU and the NVIDIA GeForce RTX 5070 Ti SUPER. This means the two products have never been measured against each other in the same test suite within this database. The absence of comparative scores limits any direct numerical comparison between the two. The only benchmark score available belongs to the NVIDIA card, which posts a 6269.5 result in the 3DMark Steel Nomad DX12 test. That score places the RTX 5070 Ti SUPER at the 36th percentile among all GPUs tracked in the database, indicating it performs below the median of all recorded graphics cards.

The AMD Steam Machine GPU, by contrast, has no benchmark scores recorded at all. Its average benchmark score is listed as 0, and its percentile versus all GPUs is 50, a placeholder value that does not reflect any tested performance. The NVIDIA card's average benchmark score is 6270, derived from the single Steel Nomad run. In terms of nearest rivals, the RTX 5070 Ti SUPER sits within a narrow band of scores: the NVIDIA GeForce RTX 4070 Ti SUPER AD102 matches it exactly with a 6270 average and a delta of 0 percent. The AMD FirePro W600 is 0.8 percent ahead, while the NVIDIA Quadro K620 trails by 0.2 percent and the AMD Radeon R7 M350 lags by 0.9 percent. These deltas are all within a single percentage point, meaning the RTX 5070 Ti SUPER's performance is tightly clustered with these four other cards in the database.

Because the AMD card has no recorded benchmarks, the head-to-head comparison cannot rely on measured scores. Instead, the analysis must fall back on architectural specifications and feature sets, which differ substantially between the two products. The RTX 5070 Ti SUPER delivers 43.94 TFLOPS of FP32 compute, while the Steam Machine GPU offers 17.56 TFLOPS. That is a 2.5 times raw compute advantage for the NVIDIA part. The pixel rate tells a similar story: 235.4 GPixel/s versus 156.8 GPixel/s, a 50 percent lead. Texture rate sits at 686.6 GTexel/s for NVIDIA versus 274.4 GTexel/s for AMD, a 150 percent margin. These numbers, derived from the specification sheets, indicate a massive throughput gap in favor of the RTX 5070 Ti SUPER.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0, with the codename Hotpink Bonefish. It belongs to the console GPU generation designed for Valve's Steam Machine hardware. The NVIDIA GeForce RTX 5070 Ti SUPER uses the GB203 chip on the Blackwell 2.0 architecture, part of the GeForce 50-series lineup. Process nodes differ as well: AMD's chip is fabricated on a 6 nm process at TSMC, while NVIDIA's uses a 5 nm process, also at TSMC. The smaller node allows for higher transistor density, measured at 120.6 million transistors per square millimeter for the NVIDIA chip versus 65.2 million for the AMD chip.

Transistor counts further separate the two. The GB203 packs 45,600 million transistors on a 378 mm² die. The Navi 33 contains 13,300 million transistors on a 204 mm² die. That means the NVIDIA chip has more than three times the transistor budget, spread across a die that is 85 percent larger by area. The density advantage of the 5 nm node is evident: NVIDIA fits nearly twice as many transistors per square millimeter. The die size difference also affects physical dimensions of the finished cards. The AMD Steam Machine GPU measures 156 mm in length, 152 mm in height, and 162 mm in width, a compact square-ish package. The NVIDIA card stretches to 304 mm in length, 137 mm in height, and 48 mm in width, a long dual-slot design.

The memory subsystems diverge completely. AMD uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. NVIDIA uses 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s. That is a 3.1 times bandwidth advantage for the RTX 5070 Ti SUPER, and double the memory capacity. The clock speeds also differ: AMD's base clock is 1720 MHz with a boost of 2450 MHz and a game clock of 2250 MHz. NVIDIA's base is 2295 MHz with a boost of 2452 MHz. The memory clocks are 2250 MHz (18 Gbps effective) for AMD and 1750 MHz (28 Gbps effective) for NVIDIA, with the faster GDDR7 signaling compensating for a lower base frequency.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti SUPER wins decisively in every measurable compute and throughput category. Its FP32 performance of 43.94 TFLOPS is 2.5 times the AMD part's 17.56 TFLOPS. Its FP16 performance matches its FP32 at 1:1 ratio, also 43.94 TFLOPS versus 17.56 TFLOPS. The texture rate of 686.6 GTexel/s dwarfs the 274.4 GTexel/s of the AMD card. The pixel rate of 235.4 GPixel/s exceeds 156.8 GPixel/s. The NVIDIA card also carries more shading units (8960 versus 1792), more texture mapping units (280 versus 112), more render output units (96 versus 64), more ray tracing cores (70 versus 28), and 280 tensor cores that the AMD card lacks entirely. The RTX 5070 Ti SUPER also supports a PCIe 5.0 x16 bus interface, while the AMD card lists no bus interface at all.

The AMD Steam Machine GPU does hold advantages in a few specific areas. Its power consumption is far lower, with a TDP of 110 W versus 350 W for the NVIDIA card. That is a 240 W difference, making the AMD part suitable for compact console enclosures with no external power connectors required. The AMD card lists no power connectors, meaning it draws power solely from the slot or an embedded system. The NVIDIA card requires a single 16-pin connector. The AMD card's physical footprint is also much smaller, at roughly half the length of the NVIDIA card. For a console form factor, the AMD GPU's dimensions and power profile are clear wins. The AMD card also lists a slightly higher boost clock at 2450 MHz versus 2452 MHz for NVIDIA, though this is a negligible 2 MHz difference.

For ray tracing workloads, the NVIDIA card has 70 RT cores versus 28 on the AMD card, a 2.5 times count advantage. For AI or tensor workloads, the NVIDIA card's 280 tensor cores provide capabilities the AMD card cannot match, as the AMD part has no tensor cores listed. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical. Display outputs differ: AMD offers 1x HDMI 2.1a and 1x DisplayPort 2.1, while NVIDIA offers 1x HDMI 2.1b and 3x DisplayPort 2.1b, giving the NVIDIA card more display connectivity options.
