AMD Radeon RX 9070 GRE vs AMD Steam Machine GPU Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Radeon RX 9070 GRE and the AMD Steam Machine GPU. The RX 9070 GRE carries two benchmark entries in the database: a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. The Steam Machine GPU has no benchmark scores recorded, which places it at the 50th percentile of all GPUs with an average benchmark score of 0.

The RX 9070 GRE sits at the 87th percentile of all GPUs, with an average benchmark score of 57367. Its nearest rivals in the database include the Intel Arc A580 at an average score of 57756 (0.7% ahead of the RX 9070 GRE), the AMD Radeon RX 5600 OEM at 58085 (1.2% ahead), the Intel Arc A570M at 58239 (1.5% ahead), and the AMD Radeon RX 6950 XT at 58392 (1.8% ahead). The RX 9070 GRE trails each of these four recorded rivals by a narrow margin, between 0.7% and 1.8% in average benchmark score.

The Steam Machine GPU, by contrast, has no nearest rivals recorded and no benchmark data, so its comparative standing rests entirely on its 50th percentile placement. The absence of measured scores for the Steam Machine GPU means the database cannot quantify any performance delta between the two cards. What is clear from the data is that the RX 9070 GRE delivers a 3DMark Steel Nomad DX12 score of 5424, a result that places it firmly in the upper half of all recorded GPUs, while the Steam Machine GPU has no comparable entry.

Where Each One Wins

The RX 9070 GRE shows its strengths in compute and raster workloads. Its FP32 throughput of 34.28 TFLOPS is double the Steam Machine GPU's 17.56 TFLOPS. Pixel rate for the RX 9070 GRE reaches 267.8 GPixel/s versus 156.8 GPixel/s, and texture rate reaches 535.7 GTexel/s versus 274.4 GTexel/s. These figures indicate that the RX 9070 GRE will dominate in any workload that scales with shading units, texture mapping, or pixel output.

The Steam Machine GPU wins in power efficiency. Its TDP is 110 W, exactly half of the RX 9070 GRE's 220 W. It requires no power connectors, whereas the RX 9070 GRE uses two 8-pin connectors and recommends a 550 W power supply. The Steam Machine GPU is also physically compact at 156 mm by 152 mm by 162 mm, though the RX 9070 GRE has no recorded dimensions for comparison. The Steam Machine GPU has a higher base clock of 1720 MHz versus 1420 MHz, and a higher game clock of 2250 MHz versus 2220 MHz. Its boost clock of 2450 MHz is lower than the RX 9070 GRE's 2790 MHz, but the base and game clock advantages suggest the Steam Machine GPU runs closer to its peak in sustained loads.

Memory bandwidth favors the RX 9070 GRE at 432.0 GB/s versus 288.0 GB/s, and the RX 9070 GRE has 12 GB of GDDR6 memory versus 8 GB. These differences point to the RX 9070 GRE winning in high-resolution textures, large scene complexity, and any workload that exceeds 8 GB of video memory. The Steam Machine GPU wins in scenarios where power draw, cooling requirements, and physical footprint are the limiting factors.

Architecture Differences

The RX 9070 GRE uses the Navi 48 chip built on RDNA 4.0 architecture, manufactured on a 4 nm process at TSMC. The Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, manufactured on a 6 nm process also at TSMC. The RX 9070 GRE belongs to the Navi IV (RX 9000) generation, while the Steam Machine GPU is classified as a Console GPU (Valve) with the codename Hotpink Bonefish.

Transistor counts differ substantially. The Navi 48 chip contains 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million per mm². The Navi 33 chip contains 13,300 million transistors on a 204 mm² die, yielding a density of 65.2 million per mm². The RX 9070 GRE packs more than four times the transistor count into a die that is roughly 75% larger.

Compute resources scale accordingly. The RX 9070 GRE has 3072 shading units, 192 texture mapping units, 96 ROPs, and 48 ray tracing cores. The Steam Machine GPU has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither card has tensor cores recorded in the database.

Memory subsystems also diverge. The RX 9070 GRE uses a 192-bit bus with 12 GB of GDDR6 memory, while the Steam Machine GPU uses a 128-bit bus with 8 GB of GDDR6 memory. Both run memory at 2250 MHz with 18 Gbps effective data rate. The RX 9070 GRE connects via PCIe 5.0 x16, while the Steam Machine GPU has no bus interface recorded. Display outputs differ as well: the RX 9070 GRE provides one HDMI 2.1b port and three DisplayPort 2.1a ports, while the Steam Machine GPU provides one HDMI 2.1a port and one DisplayPort 2.1 port.

The RX 9070 GRE is a dual-slot card, while the Steam Machine GPU has no slot width recorded. The RX 9070 GRE was released on May 7, 2025, with a launch MSRP of 549 USD. The Steam Machine GPU has a release date of June 28, 2026, and no launch MSRP recorded. The RX 9070 GRE lists its predecessor as Navi III, while the Steam Machine GPU has no predecessor or successor recorded. Both cards have an Active production status.

The Verdict

The data supports a clear split between these two cards. The RX 9070 GRE is the stronger performer by every measured compute metric: double the FP32 throughput, double the texture rate, 70% higher pixel rate, 50% more memory bandwidth, and 50% more memory capacity. Its 87th percentile ranking among all GPUs, supported by a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309, places it in the upper tier of the database. Its average benchmark score of 57367 lands within 1.8% of four recorded rivals, all of which sit slightly ahead.

The Steam Machine GPU occupies a different position. Its 50th percentile ranking and absence of any benchmark scores mean the database offers no measured evidence of its real-world performance. What the recorded specifications show is a compact, low-power part: 110 W TDP, no power connectors, and physical dimensions of 156 mm by 152 mm by 162 mm. Its RDNA 3.0 architecture, 6 nm process, and 13,300 million transistors make it a smaller and older design than the RX 9070 GRE's RDNA 4.0, 4 nm, 53,900 million transistor configuration.

Buyers who prioritize measured performance, memory capacity, and modern architecture should select the RX 9070 GRE. Buyers who require minimal power draw, no external power connectors, and a small physical footprint should consider the Steam Machine GPU, though the lack of recorded benchmark data means its actual performance level remains unverified in the database. The two cards do not compete in the same performance class; the RX 9070 GRE leads in every recorded metric except base clock, game clock, TDP, and physical size.
