AMD Steam Machine GPU vs NVIDIA GeForce RTX 4070 Ti Comparison

Where Each One Wins

The recorded data shows a decisive split between these two parts. The AMD Steam Machine GPU has no benchmark entries in the database, while the NVIDIA GeForce RTX 4070 Ti has ten recorded benchmark scores across DirectX, OpenCL, Vulkan, and compute workloads. Consequently, the RTX 4070 Ti claims all measured wins in this comparison. The AMD part holds a percentile ranking of 50 against all GPUs, which places it at the midpoint of the database distribution. The RTX 4070 Ti sits at the 84th percentile, indicating it outperforms the vast majority of recorded graphics processors. The Steam Machine GPU carries an average benchmark score of zero, meaning the database contains no measurable performance data for it. The RTX 4070 Ti averages 44,795 points across its benchmark suite, a figure that reflects its standing among the top 16 percent of all GPUs in the database.

The absence of head-to-head benchmark data in the records means the wins must be attributed based on the individual benchmark availability. The RTX 4070 Ti wins in every category where measurements exist: DirectX 9, 10, 11, and 12 tests, OpenCL compute, Vulkan rendering, 2D graphics, 3D graphics, and general GPU compute. The Steam Machine GPU does not register a single win because the database holds no scores for it. This is not a close contest; it is a comparison where one side has substantial measured data and the other has none.

Architecture Differences

The two GPUs diverge fundamentally in their underlying design. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename "Hotpink Bonefish." It belongs to the Console GPU generation for Valve, fabricated on a 6 nm process at TSMC. The die contains 13,300 million transistors on a 204 mm² slice of silicon, yielding a transistor density of 65.2 million per square millimeter. The NVIDIA GeForce RTX 4070 Ti uses the AD104 chip based on Ada Lovelace architecture, part of the GeForce 40-series. It is built on a 5 nm TSMC process, with 35,800 million transistors on a 294 mm² die, achieving a transistor density of 121.8 million per square millimeter. The NVIDIA part packs nearly 2.7 times more transistors into a die that is only 44 percent larger, reflecting a significantly denser design.

Memory configurations differ sharply. The AMD part uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s. That is 75 percent more memory capacity and 75 percent more bandwidth. Clock behavior also differs: the AMD chip runs a base clock of 1720 MHz, a boost of 2450 MHz, and a game clock of 2250 MHz. The RTX 4070 Ti has a base clock of 2310 MHz and a boost of 2610 MHz, with memory running at 1313 MHz or 21 Gbps effective. The AMD memory runs at 2250 MHz or 18 Gbps effective.

Compute resources show a wide gap. The AMD GPU has 1,792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. It has no tensor cores. The RTX 4070 Ti has 7,680 shading units, 240 TMUs, 80 ROPs, 60 RT cores, and 240 tensor cores. The shading unit count is 4.3 times higher on the NVIDIA part. Pixel rate reaches 156.8 GPixel/s on the AMD chip versus 208.8 GPixel/s on the NVIDIA chip. Texture rate stands at 274.4 GTexel/s versus 626.4 GTexel/s. FP32 throughput is 17.56 TFLOPS on the AMD part versus 40.09 TFLOPS on the NVIDIA part, a 2.3 times advantage. FP16 figures match the FP32 numbers on both, with a 1:1 ratio.

Power and physical characteristics diverge as well. The AMD Steam Machine GPU draws 110 W TDP and requires no power connectors, suggesting it is designed for an integrated console environment. The RTX 4070 Ti draws 285 W TDP, uses a single 16-pin connector, and recommends a 600 W power supply. The AMD card measures 156 mm in length, 152 mm in height, and 162 mm in width. The NVIDIA card is 285 mm long, 112 mm tall, and 42 mm wide, and occupies a dual-slot profile. The AMD card uses a PCIe bus interface that is not recorded, while the NVIDIA card uses PCIe 4.0 x16. Display outputs differ: the AMD card offers 1x HDMI 2.1 and 1x DisplayPort 2.1, while the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Production status separates them further. The AMD Steam Machine GPU remains active in production, with a release date of June 28, 2026. The RTX 4070 Ti is end-of-life, released January 2, 2023, with a predecessor in GeForce 30 and a successor in GeForce 50. The AMD part has no recorded predecessor or successor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Steam Machine GPU and the NVIDIA GeForce RTX 4070 Ti. The wins counter shows zero for the AMD side and zero for the NVIDIA side in the headToHeadBenchmarks field. However, the RTX 4070 Ti has a full benchmark suite that can be examined against the database average and nearest rivals.

The RTX 4070 Ti scores 5,024 in 3DMark Steel Nomad DX12. In Geekbench OpenCL it reaches 176,953, and in Geekbench Vulkan it reaches 213,808. PassMark tests show 187 in DirectX 10, 288 in DirectX 11, 116 in DirectX 12, and 352 in DirectX 9. The 2D graphics score is 1,200, while the 3D graphics score is 31,624. GPU compute in PassMark registers 18,396. These scores combine to an average of 44,795 points.

The nearest rivals in the database provide context for the RTX 4070 Ti's standing. The NVIDIA GeForce RTX 5090 Mobile scores 45,152 on average, which is 0.8 percent higher than the RTX 4070 Ti. The AMD Radeon Pro 5500 XT scores 45,384, 1.3 percent higher. The NVIDIA RTX A6000 scores 44,075, which is 1.6 percent lower. The Intel Arc A730M scores 45,592, 1.7 percent higher. The RTX 4070 Ti sits within a narrow band of roughly 3.3 percentage points among these four rivals, with the RTX A6000 being the only one it beats. Its 84th percentile ranking confirms that it sits above the median but not at the top of the database.

The AMD Steam Machine GPU has no benchmark scores to compare, so no exact numbers exist for its performance. The database records its percentile as 50, which is the median. Since its average benchmark score is zero, the percentile likely derives from architectural characteristics or other recorded fields rather than measured tests.

The Verdict

The data supports a clear choice for users who need measured performance: the NVIDIA GeForce RTX 4070 Ti is the only one of the two with benchmark results in the database. It holds an 84th percentile ranking, an average score of 44,795, and a full suite of DirectX, Vulkan, and compute measurements. The AMD Steam Machine GPU has no recorded benchmark scores, an average of zero, and a 50th percentile ranking. Any workload that relies on DirectX 9 through 12, OpenCL, Vulkan, 2D or 3D graphics, or general compute will find measurable support only on the NVIDIA side.

The architectural data reinforces this. The RTX 4070 Ti offers more shading units, more texture units, more render output units, more ray tracing cores, tensor cores, higher clocks, more memory, and wider bandwidth. The AMD part has a lower TDP and a smaller physical footprint, which may suit a console-style integration, but the database contains no performance evidence to support that choice. The RTX 4070 Ti is end-of-life, while the AMD part is active, but production status does not change the measured results.

Users who prioritize compact design and low power draw may consider the AMD Steam Machine GPU, as it uses no power connectors and consumes 110 W. Users who prioritize compute throughput, memory bandwidth, and DirectX performance should select the RTX 4070 Ti based on the recorded scores. The percentile gap, 50 versus 84, and the absence of AMD benchmark data make the NVIDIA part the only verifiable performer in this comparison.
