AMD Radeon RX 7700 vs AMD Steam Machine GPU Comparison

AMD Radeon RX 7700 and AMD Steam Machine GPU are both built on the RDNA 3.0 architecture, but they occupy very different positions in the database. The RX 7700 is a full desktop add-in board with an average benchmark score of 15852, placing it in the 58th percentile of all GPUs. The Steam Machine GPU, a console-oriented part, has no recorded benchmark scores and sits at the 50th percentile with an average score of zero. The data shows a clear performance gap, but the specifications reveal a more nuanced story about their intended roles.

Head-to-Head Benchmarks

The head-to-head comparison is limited because the Steam Machine GPU has no entries in the benchmark database. All nine recorded benchmarks belong solely to the RX 7700. The 3DMark Steel Nomad DX12 test shows a score of 2865, while Geekbench OpenCL returns 106028. PassMark tests provide a wider spread: DirectX 9 scores 261, DirectX 10 scores 92, DirectX 11 scores 186, and DirectX 12 scores 96. The PassMark G2D score is 1206, G3D is 20974, and GPU compute is 10963. The average of all these figures, 15852, positions the RX 7700 in the 58th percentile.

Without any Steam Machine GPU benchmark data, the delta between the two cannot be calculated directly. The RX 7700's nearest rivals in the database include the AMD Radeon R9 370X with an average score of 15862 and a delta of -0.1 percent, meaning the RX 7700 is essentially tied with that older card. The AMD Radeon RX 9060 scores 16014, putting it 1 percent ahead of the RX 7700. The AMD Radeon Pro W5500 trails by 1.1 percent with a score of 15679, and the NVIDIA GeForce RTX 3060 Ti leads by 1.7 percent at 16129. These narrow margins indicate the RX 7700 sits in a competitive mid-range cluster.

The Steam Machine GPU lacks any comparable scores, so its performance can only be inferred from its hardware configuration. Its 17.56 TFLOPS FP32 throughput is notably lower than the RX 7700's 25.18 TFLOPS. The pixel rate of 156.8 GPixel/s and texture rate of 274.4 GTexel/s are also substantially below the RX 7700's 236.1 GPixel/s and 393.4 GTexel/s. These figures suggest the Steam Machine GPU would deliver roughly two-thirds to three-quarters of the RX 7700's raw compute capability, depending on the workload.

Where Each One Wins

The RX 7700 wins on every measurable performance metric in the available data. Its 2560 shading units, 160 texture mapping units, and 96 raster output processors exceed the Steam Machine GPU's 1792 shaders, 112 TMUs, and 64 ROPs. The ray tracing core count also favors the RX 7700 at 40 versus 28. Memory capacity doubles from 8 GB to 16 GB, and the memory bus widens from 128 bit to 256 bit, pushing bandwidth from 288.0 GB/s to 624.1 GB/s. These are decisive advantages for high-resolution textures, multi-tasking, and compute-heavy applications.

The Steam Machine GPU wins on power efficiency and physical footprint. Its TDP of 110 W is less than the RX 7700's 200 W, and it requires no external power connectors. The card measures 156 mm by 152 mm by 162 mm, which is shorter in length than the RX 7700's 267 mm but taller and wider. The Steam Machine GPU's 6 nm process node, versus the RX 7700's 5 nm node, suggests a different optimization target: lower power draw in a constrained console chassis. The 13,300 million transistors on a 204 mm² die yield a density of 65.2M per mm², while the RX 7700 packs 28,100 million transistors into 346 mm² for 81.2M per mm².

For gaming at 1080p or 1440p with medium settings, the Steam Machine GPU's 17.56 TFLOPS and 288.0 GB/s bandwidth are likely sufficient, but the RX 7700's higher compute and memory throughput would handle higher frame rates, ray tracing, and 4K resolutions more comfortably. The database shows no scenario where the Steam Machine GPU outperforms the RX 7700 in raw speed, but its lower power draw makes it a better fit for systems with strict thermal or electrical limits.

Specification Differences

The RX 7700 and Steam Machine GPU differ across nearly every core specification. The RX 7700 has 2560 shading units, 160 TMUs, 96 ROPs, and 40 ray tracing cores. The Steam Machine GPU has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The RX 7700's base clock is 1900 MHz versus 1720 MHz, its game clock is 2041 MHz versus 2250 MHz, and its boost clock is 2459 MHz versus 2450 MHz. Memory clocks also differ: 2438 MHz (19.5 Gbps effective) versus 2250 MHz (18 Gbps effective).

Memory capacity and bus width are major differentiators. The RX 7700 has 16 GB of GDDR6 on a 256 bit bus, while the Steam Machine GPU has 8 GB on a 128 bit bus. This results in bandwidth of 624.1 GB/s versus 288.0 GB/s. The RX 7700's pixel rate is 236.1 GPixel/s versus 156.8 GPixel/s, texture rate is 393.4 GTexel/s versus 274.4 GTexel/s, and FP32 throughput is 25.18 TFLOPS versus 17.56 TFLOPS. FP16 is also 25.18 TFLOPS versus 17.56 TFLOPS, both at a 1:1 ratio.

Power and physical specifications diverge sharply. The RX 7700 has a TDP of 200 W, requires two 8-pin power connectors, and a suggested PSU of 550 W. The Steam Machine GPU has a TDP of 110 W, no power connectors, and no suggested PSU. The RX 7700 is a dual-slot card measuring 267 mm by 135 mm by 50 mm. The Steam Machine GPU measures 156 mm by 152 mm by 162 mm. The RX 7700 uses a PCIe 4.0 x16 interface, while the Steam Machine GPU has no listed bus interface. Display outputs also differ: the RX 7700 has one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C, while the Steam Machine GPU has one HDMI 2.1a and one DisplayPort 2.1.

Architecture Differences

Both GPUs share the RDNA 3.0 architecture, but they use different chips and process nodes. The RX 7700 is built on the Navi 32 chip with the codename Wheat Nas, using a 5 nm process at TSMC. The Steam Machine GPU uses the Navi 33 chip with the codename Hotpink Bonefish, fabricated on a 6 nm process. Transistor counts differ significantly: 28,100 million for the RX 7700 versus 13,300 million for the Steam Machine GPU. Die sizes are 346 mm² versus 204 mm², yielding transistor densities of 81.2M per mm² and 65.2M per mm², respectively.

The RX 7700 belongs to the Radeon RX 7000 series and the Navi III (RX 7000) generation. The Steam Machine GPU has no series designation and is classified as a Console GPU (Valve). The RX 7700 lists a predecessor as Navi II and a successor as Navi IV, while the Steam Machine GPU has neither. Release dates also differ: the RX 7700 was released on September 17, 2025, and the Steam Machine GPU on June 28, 2026. Both are marked as Active in production status.

The cache hierarchy is not listed in the database, so no comparison can be made on L2 or L3 cache sizes. The RX 7700's higher transistor density and larger die suggest a more complex design with additional compute resources, which aligns with its higher shading unit, TMU, and ROP counts. The Steam Machine GPU's smaller die and lower transistor count point to a leaner configuration optimized for a fixed-function console environment.

The Verdict

The RX 7700 is the clear choice for any workload requiring maximum compute throughput. Its 25.18 TFLOPS FP32, 624.1 GB/s memory bandwidth, and 16 GB of VRAM provide a substantial margin over the Steam Machine GPU in every category. The benchmark data confirms this: the RX 7700 averages 15852 across nine tests, ranking in the 58th percentile. It trails the RTX 3060 Ti by only 1.7 percent and matches the R9 370X within 0.1 percent, placing it in a competitive mid-range tier.

The Steam Machine GPU, with no benchmarks and a 50th percentile score, cannot be directly ranked. Its 17.56 TFLOPS and 288.0 GB/s bandwidth indicate roughly 70 percent of the RX 7700's raw compute and 46 percent of its bandwidth. The lower 110 W TDP and compact dimensions make it suitable for small-form-factor or power-constrained systems, but the lack of data means its real-world performance remains unverified in the database.

For users who prioritize raw performance, the RX 7700 is the only option with recorded evidence. The Steam Machine GPU's role appears to be a console-specific part where power efficiency and size matter more than peak performance. The data does not support any scenario where the Steam Machine GPU outperforms the RX 7700, and it does not provide enough information to recommend it for general desktop use. The RX 7700 delivers measurable, competitive results; the Steam Machine GPU remains an unproven quantity.
