AMD Radeon RX 7700S vs AMD Steam Machine GPU Comparison

Head-to-Head Benchmarks

The database contains three recorded benchmark scores for the AMD Radeon RX 7700S, while the AMD Steam Machine GPU currently has no recorded benchmark entries. This makes a direct score-to-score comparison impossible for most tests. However, the available data for the RX 7700S provides a reference point for its positioning. The RX 7700S scores 2185 in 3DMark Steel Nomad DX12, 62983 in Geekbench OpenCL, and 36380 in Geekbench Vulkan. Its average benchmark score is 33849, placing it at the 78th percentile among all GPUs in the database.

Because the Steam Machine GPU lacks any recorded scores, the head-to-head analysis must rely on the theoretical specifications and the architectural relationship between the two. The Steam Machine GPU uses the same Navi 33 chip, so the performance gap is expected to be modest. The RX 7700S delivers 20.48 TFLOPS FP32, while the Steam Machine GPU delivers 17.56 TFLOPS FP32. That is a 16.6% advantage for the RX 7700S in raw floating-point throughput. In FP16 compute, the difference is larger: the RX 7700S reaches 40.96 TFLOPS with a 2:1 ratio, while the Steam Machine GPU is capped at 17.56 TFLOPS with a 1:1 ratio. Applications that use FP16 heavily will favor the RX 7700S substantially.

The nearest rivals for the RX 7700S give context to its performance tier. Its average score sits within 0.7% of the NVIDIA RTX A5000, which records 33622, and within 0.5% of the NVIDIA GeForce GTX 1060 5 GB, which records 33694. The RX 7700S trails the AMD Radeon HD 7950 by 0.3% and the AMD Radeon RX 480 by 0.4%. These deltas are small, indicating that the RX 7700S performs in a narrow band around these older or higher-tier cards. The Steam Machine GPU, with fewer shading units and lower clock speeds, would logically land below the RX 7700S in most tests, though the absence of benchmark data prevents a precise delta.

Architecture Differences

Both GPUs share the Navi 33 chip, RDNA 3.0 architecture, and the Hotpink Bonefish codename. They are built on the same 6 nm TSMC process with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². The memory subsystem is identical: 8 GB of GDDR6 on a 128 bit bus with 288.0 GB/s of bandwidth and a memory clock of 2250 MHz, or 18 Gbps effective. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The key differences appear in the compute configuration and clock behavior. The RX 7700S uses 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The Steam Machine GPU uses fewer resources: 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. That is a reduction of 256 shading units, 16 TMUs, and 4 ray tracing cores. The ROP count stays identical at 64.

Clock speeds differ as well. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. The Steam Machine GPU runs a higher base clock of 1720 MHz, a slightly lower boost clock of 2450 MHz, and a higher game clock of 2250 MHz. The higher base and game clocks on the Steam Machine GPU partially offset its lower core count. Pixel rate favors the RX 7700S at 160.0 GPixel/s versus 156.8 GPixel/s. Texture rate favors the RX 7700S more clearly: 320.0 GTexel/s versus 274.4 GTexel/s.

The Steam Machine GPU is a console part for Valve, while the RX 7700S belongs to the Radeon RX 7000 series in the Navi Mobile (RX 7000M) generation. The RX 7700S draws 100 W TDP, while the Steam Machine GPU draws 110 W TDP. The RX 7700S uses a PCIe 4.0 x16 bus interface and has no power connectors, fitting an IGP slot width. The Steam Machine GPU has no recorded bus interface, uses a 156 mm by 152 mm by 162 mm board, and offers 1x HDMI 2.1a and 1x DisplayPort 2.1 outputs. The RX 7700S display outputs are listed as portable device dependent. The Steam Machine GPU releases in 2026, while the RX 7700S released in 2023.

The Verdict

The data indicates that the AMD Radeon RX 7700S is the stronger GPU on paper. It holds advantages in shading units, texture units, ray tracing cores, FP32 compute, FP16 compute, pixel rate, and texture rate. Its 20.48 TFLOPS FP32 output is 16.6% above the Steam Machine GPU's 17.56 TFLOPS. The RX 7700S also has a higher boost clock and lower TDP at 100 W versus 110 W. For users prioritizing raw compute and texture throughput, the RX 7700S is the clear choice.

The Steam Machine GPU is not without merits. It runs a higher base clock and higher game clock, which can help maintain performance in sustained workloads. Its console-oriented design with fixed display outputs (1x HDMI 2.1a and 1x DisplayPort 2.1) and compact dimensions (156 mm by 152 mm by 162 mm) suit an integrated console form factor. The RX 7700S, by contrast, has portable device dependent outputs and an IGP slot width, indicating a laptop-oriented design.

The RX 7700S also benefits from an established benchmark record. Its average score of 33849 places it at the 78th percentile, with nearest rivals within a 1.0% band. The Steam Machine GPU has no recorded scores, so its real-world standing remains unverified. Buyers who need confirmed performance data should favor the RX 7700S. Those targeting a console-style build with the Steam Machine GPU will rely on its architectural similarity to the RX 7700S rather than direct measurements.

Where Each One Wins

The RX 7700S wins in compute-heavy workloads. Its 2048 shading units and 128 TMUs provide 320.0 GTexel/s of texture rate, which is 16.6% higher than the Steam Machine GPU's 274.4 GTexel/s. FP32 performance also favors the RX 7700S at 20.48 TFLOPS versus 17.56 TFLOPS. For FP16 tasks, the RX 7700S has a decisive advantage with 40.96 TFLOPS versus 17.56 TFLOPS, assuming the workload can use the 2:1 ratio. Ray tracing workloads should favor the RX 7700S as well, since it has 32 ray tracing cores versus 28.

The Steam Machine GPU wins in power-adjusted clock behavior. Its base clock of 1720 MHz is 14.7% higher than the RX 7700S's 1500 MHz, and its game clock of 2250 MHz is 2.3% higher. This means the Steam Machine GPU may sustain higher clocks in scenarios where the RX 7700S drops toward its base frequency. The Steam Machine GPU also consumes 110 W TDP, which is higher than the RX 7700S's 100 W, suggesting it can push more power into the same Navi 33 die. Its fixed display outputs and compact dimensions make it better suited for a console chassis, while the RX 7700S's IGP slot width and portable device dependent outputs target laptops.

In terms of confirmed performance, the RX 7700S is the only one with recorded data. Its 78th percentile ranking and closeness to the NVIDIA RTX A5000 (within 0.7%) and GTX 1060 5 GB (within 0.5%) give it a verified position. The Steam Machine GPU has none of that evidence, so its wins are limited to theoretical clock advantages and form factor suitability. The RX 7700S is the better choice for compute, texture, and ray tracing workloads. The Steam Machine GPU is the better choice for a fixed console environment where higher base clocks and a compact board matter more than peak throughput.
