AMD Radeon 890M vs AMD Steam Machine GPU Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark profile for the AMD Radeon 890M, while the AMD Steam Machine GPU currently has no recorded benchmark scores. This makes a direct score-for-score comparison impossible. However, the 890M's recorded results establish a clear performance baseline that can be weighed against the Steam Machine GPU's specifications and overall percentile ranking.

The Radeon 890M delivers a 3DMark Steel Nomad DX12 score of 590. In Geekbench, it records 37,254 in OpenCL and 40,808 in Vulkan. Passmark results show 8,076 in G3D, 979 in G2D, and 4,157 in GPU compute. Legacy DirectX tests return scores of 97 in DX9, 73 in DX11, 37 in DX12, and 33 in DX10. These figures place the 890M at the 45th percentile among all GPUs in the database, with an average benchmark score of 9,210.

The Steam Machine GPU holds the 50th percentile overall, a higher standing than the 890M's 45th percentile. This percentile difference indicates that, despite lacking individual benchmark entries, the Steam Machine GPU is positioned above roughly half of all recorded GPUs, while the 890M sits just below that midpoint. The Steam Machine GPU's average benchmark score is listed as zero, which reflects the absence of recorded tests rather than actual performance.

The 890M's nearest rivals in the database provide additional context for its standing. It trails the AMD Radeon Vega 8 by 0.1% (9,221 average score), the NVIDIA GeForce GTX 960 by 0.7% (9,273), the NVIDIA GeForce GTX 465 by 0.9% (9,294), and the NVIDIA GeForce GTX 850M by 1% (9,302). These margins are narrow, placing the 890M within 1% of four distinct GPUs spanning integrated and discrete designs.

Given the Steam Machine GPU's 50th percentile ranking and its substantially higher compute specifications, the data suggests it would outperform the 890M in most scenarios. The Steam Machine GPU's FP32 throughput of 17.56 TFLOPS is nearly three times the 890M's 5.939 TFLOPS. Its texture rate of 274.4 GTexel/s and pixel rate of 156.8 GPixel/s both exceed the 890M's 185.6 GTexel/s and 92.80 GPixel/s respectively. These raw throughput advantages point to a significant performance gap, though the lack of direct benchmark scores prevents a precise percentage comparison.

The Verdict

The benchmark data indicates two GPUs with different roles and performance expectations. The Radeon 890M is a fully measured integrated graphics processor with modest scores that place it just below the median of all recorded GPUs. Its average benchmark score of 9,210 and 45th percentile ranking confirm it as a capable but not exceptional performer, suitable for light gaming and general graphics workloads.

The Steam Machine GPU, despite having no individual benchmark results, holds a higher 50th percentile ranking. Its specification sheet shows a discrete-class GPU with dedicated GDDR6 memory, a 128-bit memory bus, and 288.0 GB/s of bandwidth. The 8 GB memory capacity is fixed, unlike the 890M's system-shared memory, which is dependent on the host system's RAM configuration. For users who need consistent, predictable graphics memory, the Steam Machine GPU's dedicated allocation is a clear advantage.

Users should choose the Radeon 890M for integrated graphics duty in thin-and-light portable devices where power consumption matters. Its 15 W TDP is a fraction of the Steam Machine GPU's 110 W, and it requires no power connectors. The Steam Machine GPU, with its higher TDP, larger physical dimensions (156 mm by 152 mm by 162 mm), and discrete memory, targets a different segment: compact gaming consoles or similar fixed hardware where power and space constraints are less severe.

Architecture Differences

The two GPUs come from different architectural generations. The Radeon 890M uses RDNA 3.5 on a 4 nm TSMC process, while the Steam Machine GPU uses RDNA 3.0 on a 6 nm TSMC process. The 890M's chip is named Strix Point, and its generation is listed as Navi III IGP (Strix Point Mobile). The Steam Machine GPU's chip is Navi 33, with the codename Hotpink Bonefish, and its generation is Console GPU (Valve).

Transistor counts differ substantially. The 890M packs 34,000 million transistors on a 233 mm² die, yielding a transistor density of 145.9M per mm². The Steam Machine GPU contains 13,300 million transistors on a 204 mm² die, with a density of 65.2M per mm². The 890M's smaller process node allows more than double the transistor density despite a larger transistor budget.

Compute resources also diverge. The 890M has 1,024 shading units, 64 texture mapping units, 32 raster operation units, and 16 ray tracing cores. The Steam Machine GPU scales up to 1,792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. The Steam Machine GPU's FP16 performance matches its FP32 at 17.56 TFLOPS (1:1), while the 890M also runs FP16 at 5.939 TFLOPS (1:1).

Clock behavior differs by design. The 890M operates at a 400 MHz base and 2900 MHz boost, with system-shared memory clocks. The Steam Machine GPU runs at a 1720 MHz base, 2250 MHz game clock, and 2450 MHz boost, with its GDDR6 memory at 2250 MHz (18 Gbps effective). The Steam Machine GPU's higher base clock reflects its discrete nature, while the 890M's low base clock suits power-sensitive mobile scenarios.

Where Each One Wins

The Radeon 890M wins in power efficiency and integration. Its 15 W TDP allows deployment in portable devices without active cooling or dedicated power connectors. The 890M's 4 nm process node and 145.9M per mm² transistor density indicate a highly optimized design for its power envelope. Its system-shared memory approach means no dedicated VRAM allocation is needed, simplifying system design for thin laptops and handhelds. The 890M's PCIe 4.0 x8 interface provides adequate bandwidth for an integrated part, and its display outputs are portable-device dependent, matching its mobile focus.

The Steam Machine GPU wins on raw graphics throughput and memory bandwidth. Its FP32 compute of 17.56 TFLOPS, texture rate of 274.4 GTexel/s, and pixel rate of 156.8 GPixel/s all exceed the 890M's corresponding figures by wide margins. The 8 GB GDDR6 memory with 288.0 GB/s bandwidth eliminates dependence on system RAM speed and capacity, providing consistent performance regardless of the host system's memory configuration. The Steam Machine GPU's 50th percentile ranking, higher than the 890M's 45th, reinforces its stronger overall position in the database.

For gaming at higher resolutions or with ray tracing enabled, the Steam Machine GPU's 28 RT cores versus the 890M's 16 RT cores suggests better ray tracing throughput. The Steam Machine GPU's fixed 156 mm by 152 mm by 162 mm dimensions indicate a board designed for a console chassis, while the 890M's IGP slot width means it occupies no expansion slot at all.

The specification table shows two GPUs designed for entirely different environments. The 890M is an integrated part with shared resources, while the Steam Machine GPU is a discrete console-class component with dedicated memory and higher clocks. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The Steam Machine GPU's later release date and higher percentile ranking suggest it represents a newer performance tier, despite the 890M's more advanced process node.
