AMD Radeon PRO W7400 vs AMD Steam Machine GPU Comparison

Head-to-Head Benchmarks

The recorded data contains no benchmark scores for either GPU, and the head-to-head benchmark table is empty. Neither the AMD Radeon PRO W7400 nor the AMD Steam Machine GPU has any measured performance entries in the database. The wins counter for both products sits at zero, and the nearest rivals lists are also empty. This means a direct comparison of measured application performance is not possible from the database at this time.

What the database does provide is the theoretical compute capacity derived from each card's clock speeds and shader configuration. Both GPUs share the same 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The difference in raw throughput comes entirely from clock speeds. The Radeon PRO W7400 runs with a base clock of 330 MHz and a boost clock of 1100 MHz, producing 7.885 TFLOPS of FP32 performance and 7.885 TFLOPS of FP16 performance at a 1:1 ratio. The Steam Machine GPU runs with a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2450 MHz, producing 17.56 TFLOPS of FP32 and 17.56 TFLOPS of FP16 at the same 1:1 ratio.

The Steam Machine GPU delivers 2.23 times the FP32 throughput of the Radeon PRO W7400 based on the recorded clock specifications. This is a direct consequence of the 2450 MHz boost clock versus the 1100 MHz boost clock, a 1350 MHz difference. Pixel throughput tells the same story. The Steam Machine GPU reaches 156.8 GPixel/s, while the Radeon PRO W7400 reaches 70.40 GPixel/s, a difference of 86.4 GPixel/s. Texture throughput shows 274.4 GTexel/s for the Steam Machine GPU versus 123.2 GTexel/s for the Radeon PRO W7400.

Memory bandwidth is also higher on the Steam Machine GPU. It uses a memory clock of 2250 MHz with 18 Gbps effective data rate, producing 288.0 GB/s over a 128-bit bus. The Radeon PRO W7400 uses a memory clock of 1350 MHz with 10.8 Gbps effective data rate, producing 172.8 GB/s over the same 128-bit bus. The Steam Machine GPU holds a 115.2 GB/s bandwidth advantage. Both cards have 8 GB of GDDR6 memory.

The Radeon PRO W7400 does hold one clear specification win. Its power draw is listed at 55 W TDP, while the Steam Machine GPU is listed at 110 W TDP. The Radeon PRO W7400 also requires a suggested PSU of 250 W, while the Steam Machine GPU has no suggested PSU value recorded. The Radeon PRO W7400 is a single-slot card with dimensions of 168 mm length, 69 mm height, and 20 mm width. The Steam Machine GPU measures 156 mm length, 152 mm height, and 162 mm width, with no slot width recorded.

Architecture Differences

Both GPUs share the same underlying silicon. The chip is Navi 33 in both cases, using the RDNA 3.0 architecture with the codename Hotpink Bonefish. Both are manufactured by TSMC on a 6 nm process node. Both have 13,300 million transistors and a die size of 204 mm², yielding a transistor density of 65.2M per mm². The shading units, TMUs, ROPs, and ray tracing cores are identical in count: 1792, 112, 64, and 28 respectively. Neither card has tensor cores recorded.

The API support is identical. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means any software that runs on one should be compatible with the other at the API level, assuming driver support exists.

The differences are in implementation, not in the silicon itself. The Radeon PRO W7400 is binned and configured for low power operation. Its base clock of 330 MHz is dramatically lower than the Steam Machine GPU's base clock of 1720 MHz. The boost clock difference is 1100 MHz versus 2450 MHz. The Radeon PRO W7400 has no game clock recorded, while the Steam Machine GPU has a game clock of 2250 MHz, which sits between its base and boost clocks.

Memory configuration differs in clock speed only. The Radeon PRO W7400 runs its GDDR6 at 1350 MHz for an effective 10.8 Gbps, while the Steam Machine GPU runs at 2250 MHz for an effective 18 Gbps. Both use a 128-bit bus and 8 GB capacity. The higher memory clock on the Steam Machine GPU directly explains its higher bandwidth figure.

Physical design diverges significantly. The Radeon PRO W7400 is a single-slot card using no power connectors, drawing 55 W, with a suggested PSU of 250 W. It has a board length of 168 mm, height of 69 mm, and width of 20 mm. The Steam Machine GPU also uses no power connectors but draws 110 W. It measures 156 mm in length, 152 mm in height, and 162 mm in width, which is a much bulkier package. The Steam Machine GPU has no suggested PSU value and no bus interface recorded, while the Radeon PRO W7400 uses PCIe 4.0 x8.

Display outputs differ in count and type. The Radeon PRO W7400 provides 4x DisplayPort 2.1. The Steam Machine GPU provides 1x HDMI 2.1a and 1x DisplayPort 2.1. This reflects their intended roles: the Radeon PRO W7400 is a workstation card for multi-monitor setups, and the Steam Machine GPU is a console-oriented part with a single display output.

The production status for both is Active. The Radeon PRO W7400 has a release date of 2025-08-02 and a predecessor listed as Radeon Pro Vega. The Steam Machine GPU has a release date of 2026-06-28 and no predecessor recorded. Neither has a successor listed.

The Verdict

The data supports a clear split based on intended use. The AMD Steam Machine GPU is the faster part in raw compute, memory bandwidth, pixel throughput, and texture throughput. It doubles the FP32 throughput of the Radeon PRO W7400, offers 115.2 GB/s more memory bandwidth, and delivers higher pixel and texture rates. Any workload that depends on shader throughput, fill rate, or memory bandwidth will favor the Steam Machine GPU by a wide margin.

The AMD Radeon PRO W7400 is the lower-power, lower-profile option. It draws 55 W versus 110 W, requires a 250 W suggested PSU, and fits in a single-slot 168 mm package. It also provides 4x DisplayPort 2.1 outputs, which suits multi-monitor professional setups. The Steam Machine GPU provides only one HDMI 2.1a and one DisplayPort 2.1 output, which limits its usefulness in multi-display environments.

There is no benchmark data in the database to confirm real-world performance differences. The verdict rests entirely on recorded specifications. The Steam Machine GPU is the performance choice. The Radeon PRO W7400 is the efficiency and connectivity choice. Neither card has a launch MSRP recorded, so no price-based comparison is possible.

Where Each One Wins

The AMD Steam Machine GPU wins in every performance-oriented specification recorded in the database. It has a higher base clock, boost clock, and game clock. It has higher pixel rate, texture rate, FP32 throughput, and FP16 throughput. It has higher memory bandwidth. For gaming, rendering, compute workloads, or any task where shader output or memory speed matters, the Steam Machine GPU is the clear choice based on the recorded data.

The AMD Radeon PRO W7400 wins in efficiency and physical footprint. It draws 55 W versus 110 W, which is half the power draw. It requires a 250 W suggested PSU, while the Steam Machine GPU has no suggested PSU recorded. It is a single-slot card at 168 mm length, 69 mm height, and 20 mm width. The Steam Machine GPU measures 156 mm by 152 mm by 162 mm, which is a larger block. The Radeon PRO W7400 also provides four DisplayPort 2.1 outputs, enabling multi-monitor professional setups that the Steam Machine GPU cannot match with its single HDMI 2.1a and single DisplayPort 2.1.

The Radeon PRO W7400 also has a bus interface recorded as PCIe 4.0 x8, while the Steam Machine GPU has no bus interface listed. This may matter for integration into systems that require a standard PCIe slot. The Steam Machine GPU's lack of a recorded bus interface suggests it is intended for a fixed console chassis rather than a standard desktop motherboard.

In terms of release timing, the Radeon PRO W7400 launched on 2025-08-02, and the Steam Machine GPU launched on 2026-06-28. The Radeon PRO W7400 has a recorded predecessor, the Radeon Pro Vega, while the Steam Machine GPU has no predecessor. Both remain in active production.

The database shows no benchmark scores, no average scores, and no percentile rankings beyond a common 50th percentile for both. The nearest rivals lists are empty for both cards. This means the performance comparison is based strictly on the published specifications, not on measured application results. The Steam Machine GPU's specification sheet indicates a substantially faster part. The Radeon PRO W7400's specification sheet indicates a deliberately power-limited professional card with broader display connectivity. The choice between them depends on whether the workload prioritizes raw throughput or power efficiency and multi-display support.
