AMD Radeon PRO W7700 vs AMD Steam Machine GPU Comparison

AMD Radeon PRO W7700 and AMD Steam Machine GPU are both built on the RDNA 3.0 architecture, but they target fundamentally different segments of the market. The Radeon PRO W7700 is a workstation-class graphics card designed for professional workloads, while the Steam Machine GPU is a console-oriented chip developed in collaboration with Valve. The recorded data shows significant gaps in compute capacity, memory subsystem, and physical design, which translate into distinct performance profiles. This analysis draws exclusively from the database entries for both products.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, and the Steam Machine GPU has no recorded benchmark scores or average performance rating. This absence of comparative data is itself informative. The Radeon PRO W7700, by contrast, has two recorded benchmark scores: 108245 in Geekbench OpenCL and 129706 in Geekbench Vulkan. Its average benchmark score across all tests in the database is 118976, placing it in the 95th percentile of all GPUs tracked.

The Steam Machine GPU sits at the 50th percentile of all GPUs, with an average benchmark score of 0, meaning no completed tests are recorded in the database. The performance gap between these two cards cannot be quantified directly, but the percentile difference is stark. A GPU at the 95th percentile versus one at the 50th percentile indicates that the Radeon PRO W7700 sits far above the midpoint of all tracked graphics hardware, while the Steam Machine GPU sits exactly at that midpoint based on the available data.

The Radeon PRO W7700's nearest rivals in the database provide context for its performance tier. The NVIDIA GB10 scores 117393, which is 1.3% behind the Radeon PRO W7700. The NVIDIA RTX 4000 SFF Ada Generation scores 117088, 1.6% behind. The NVIDIA Tesla V100 SXM2 16 GB scores 114395, 4% behind. The NVIDIA RTX A5500 Mobile scores 113944, 4.4% behind. These deltas show the Radeon PRO W7700 leading a cluster of professional and high-end mobile GPUs by narrow margins, between 1.3% and 4.4%.

The Steam Machine GPU has no nearest rivals listed in the database, which further underscores its position as a product with insufficient benchmark data to establish competitive relationships. The Radeon PRO W7700's compute throughput, measured at 31.95 TFLOPS for FP32 and 63.90 TFLOPS for FP16 with a 2:1 ratio, stands far above the Steam Machine GPU's 17.56 TFLOPS for both FP32 and FP16 with a 1:1 ratio. These raw throughput figures, while not directly comparable to benchmark scores, indicate that the Radeon PRO W7700 delivers nearly double the FP32 compute capability.

The Verdict

The recorded data indicates that the Radeon PRO W7700 and the Steam Machine GPU occupy different performance and capability tiers. The Radeon PRO W7700's average benchmark score of 118976 places it in the 95th percentile of all GPUs, and its nearest rivals in the database are all NVIDIA professional products, with the Radeon PRO W7700 leading each by 1.3% to 4.4%. The Steam Machine GPU has no benchmark scores and sits at the 50th percentile, which represents the median of all tracked GPUs but carries no performance validation from completed tests.

Compute resources heavily favor the Radeon PRO W7700. Its 3072 shading units, 48 ray tracing cores, and 31.95 TFLOPS of FP32 throughput position it for demanding workstation tasks. The Steam Machine GPU's 1792 shading units, 28 ray tracing cores, and 17.56 TFLOPS of FP32 throughput are roughly 58% of the Radeon PRO W7700's shading unit count and ray tracing core count, and 55% of its FP32 throughput. Memory capacity and bandwidth similarly favor the Radeon PRO W7700, which offers 16 GB and 576.0 GB/s versus 8 GB and 288.0 GB/s.

The Steam Machine GPU's advantages lie in its physical and power profile. It consumes 110 W versus 190 W, uses no external power connectors, and has a smaller length dimension at 156 mm versus 241 mm. Its production status is Active, while the Radeon PRO W7700's production status is not listed. The Steam Machine GPU also includes a game clock of 2250 MHz, which the Radeon PRO W7700 does not list.

Users requiring maximum compute throughput, memory bandwidth, and professional display outputs should select the Radeon PRO W7700 based on the data. Users prioritizing lower power consumption, compact dimensions, and a console-oriented feature set with integrated power delivery should select the Steam Machine GPU. The Radeon PRO W7700's launch MSRP is 999 USD. The Steam Machine GPU has no launch MSRP listed.

The Radeon PRO W7700's pixel rate of 249.6 GPixel/s and texture rate of 499.2 GTexel/s outpace the Steam Machine GPU's 156.8 GPixel/s and 274.4 GTexel/s. These rates reflect the Radeon PRO W7700's 96 ROPs and 192 TMUs, compared to the Steam Machine GPU's 64 ROPs and 112 TMUs. The Radeon PRO W7700 also lists a suggested power supply of 450 W, while the Steam Machine GPU does not list one.

The Radeon PRO W7700's FP16 performance at 63.90 TFLOPS with a 2:1 ratio indicates it can process half-precision workloads at twice the FP32 rate, a feature absent from the Steam Machine GPU, which maintains a 1:1 ratio at 17.56 TFLOPS. This difference matters for workloads that leverage FP16 arithmetic, such as certain machine learning and graphics operations, where the Radeon PRO W7700 offers a substantial advantage.

The Steam Machine GPU's dimensions of 156 mm by 152 mm by 162 mm describe a compact, square-ish module, while the Radeon PRO W7700's 241 mm by 111 mm profile is a longer, narrower card. Neither product lists a width for the Radeon PRO W7700, so full volume comparison is not possible from the database.

Both GPUs support the same API feature set, including DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. This parity means software compatibility is not a differentiator. The Radeon PRO W7700's four DisplayPort 2.1 outputs support multi-display workstation setups, while the Steam Machine GPU's single HDMI 2.1a and single DisplayPort 2.1 output target a single display configuration.
