Architecture Differences

The AMD Steam Machine GPU is built on the RDNA 3.0 architecture, using the Navi 33 chip under the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation and is fabricated on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die, resulting in a transistor density of 65.2M per mm². This is a compact, integrated design with no power connectors and a 110 W TDP.

The Lisuan Tech LX MAX uses the TrueGPU architecture with the 7G106 chip, belonging to the 7G100 generation. It is also fabricated on a 6 nm process at TSMC, but the transistor count and die size are not recorded in the database. The LX MAX is a dual-slot card with a 16-pin power connector and a 225 W TDP, indicating a more power-hungry design.

The compute unit configurations differ substantially. The AMD part has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores. The Lisuan Tech LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs, but no dedicated RT cores are listed. This gives the LX MAX significantly higher raw pixel and texture throughput: 192.0 GPixel/s and 384.0 GTexel/s versus 156.8 GPixel/s and 274.4 GTexel/s for the AMD card.

FP32 and FP16 throughput also diverge sharply. The AMD Steam Machine GPU delivers 17.56 TFLOPS in both FP32 and FP16, indicating a 1:1 ratio. The Lisuan Tech LX MAX delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16, reflecting a 2:1 ratio. The FP16 advantage of the LX MAX is particularly pronounced, at 49.15 TFLOPS versus 17.56 TFLOPS.

Memory architecture is another clear differentiator. The AMD card uses 8 GB GDDR6 on a 128-bit bus, yielding 288.0 GB/s bandwidth. The LX MAX uses 12 GB GDDR6 on a 192-bit bus, yielding 432.0 GB/s bandwidth. Both have the same memory clock at 2250 MHz with 18 Gbps effective speed, but the wider bus gives the LX MAX a 50% bandwidth advantage.

API support is similar but not identical. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD card supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3.

Display connectivity differs in both count and standard. The AMD Steam Machine GPU provides 1x HDMI 2.1a and 1x DisplayPort 2.1. The Lisuan Tech LX MAX provides 4x DisplayPort 1.4a only, with no HDMI output.

Physical dimensions reflect their intended use cases. The AMD card is nearly square: 156 mm long, 152 mm high, and 162 mm wide. The LX MAX is a longer, slimmer card: 248 mm long, 118 mm high, and 48 mm wide. The LX MAX occupies a dual-slot profile, while the AMD card has no slot width recorded.

The Verdict

The recorded data indicates two GPUs aimed at different priorities. The AMD Steam Machine GPU is a low-power, compact solution with a 110 W TDP and no external power requirement. It delivers 17.56 TFLOPS FP32, 288.0 GB/s bandwidth, and 8 GB memory, which suits a console-style integrated environment. Its RDNA 3.0 architecture includes 28 RT cores, and it supports Vulkan 1.4 and DisplayPort 2.1.

The Lisuan Tech LX MAX is a higher-performance add-in card with a 225 W TDP, a 16-pin connector, and a 550 W suggested PSU. It delivers 24.58 TFLOPS FP32, 49.15 TFLOPS FP16, 432.0 GB/s bandwidth, and 12 GB memory. Its 6144 shading units and 192 TMUs provide higher texture and pixel rates. The LX MAX is the stronger choice for workloads that scale with raw compute throughput and memory capacity.

Users who require maximum FP32 and FP16 performance, larger memory capacity, and higher memory bandwidth should select the Lisuan Tech LX MAX. Users who prioritize low power draw, compact dimensions, and integrated console-style operation without external power connectors should select the AMD Steam Machine GPU. The data does not show a single winner; the appropriate pick depends on the power envelope and performance requirements of the target system.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark scores for these two GPUs. However, the specification data allows direct comparison of theoretical peak performance metrics.

The Lisuan Tech LX MAX holds the largest advantage in FP16 compute. It delivers 49.15 TFLOPS, which is 31.59 TFLOPS higher than the AMD Steam Machine GPU's 17.56 TFLOPS. This represents a 180% advantage for the LX MAX. The FP32 gap is smaller but still substantial: 24.58 TFLOPS versus 17.56 TFLOPS, a difference of 7.02 TFLOPS or roughly 40%.

Memory bandwidth favors the LX MAX by 144.0 GB/s, from 432.0 GB/s down to 288.0 GB/s, a 50% advantage. The LX MAX also has 4 GB more memory capacity, which can accommodate larger working sets in GPU-accelerated workloads.

Texture rate favors the LX MAX by 109.6 GTexel/s, from 384.0 GTexel/s versus 274.4 GTexel/s, a 40% advantage. Pixel rate favors the LX MAX by 35.2 GPixel/s, from 192.0 GPixel/s versus 156.8 GPixel/s, a 22% advantage.

The AMD Steam Machine GPU counters with its RT core implementation. It has 28 dedicated RT cores, whereas the LX MAX has no RT cores recorded. This gives the AMD part a distinct capability for ray-traced workloads, even though its raw compute numbers are lower.

Power efficiency also favors the AMD card. The AMD part delivers 17.56 TFLOPS FP32 within a 110 W TDP, yielding 0.16 TFLOPS per watt. The LX MAX delivers 24.58 TFLOPS FP32 within a 225 W TDP, yielding 0.11 TFLOPS per watt. The AMD card achieves roughly 45% higher FP32 efficiency per watt.

The AMD card also offers a newer display interface with DisplayPort 2.1 support, while the LX MAX uses DisplayPort 1.4a. The AMD card provides HDMI 2.1a output, which the LX MAX lacks entirely.

In physical footprint, the AMD card is shorter at 156 mm versus 248 mm for the LX MAX, making it suitable for smaller chassis. The LX MAX is thinner at 48 mm width versus 162 mm for the AMD card, but it requires a dual-slot profile and a 16-pin power connection.

The release timeline shows the LX MAX entered the market earlier on 2026-03-16, while the AMD Steam Machine GPU followed on 2026-06-28. Both remain in Active production status according to the database.

Given the absence of measured benchmark scores, the specification deltas provide the only basis for comparison. The LX MAX leads in raw throughput, memory bandwidth, and capacity. The AMD Steam Machine GPU leads in power efficiency, RT core availability, and modern display output standards.
