AMD Steam Machine GPU vs Lisuan Tech LX 7G100 Comparison

The Verdict

The AMD Steam Machine GPU and the Lisuan Tech LX 7G100 occupy different corners of the performance spectrum, and the choice between them hinges on the user's priorities regarding raw compute versus physical integration.

The Lisuan Tech LX 7G100 is the clear performance leader in this comparison. Its recorded specifications show a substantially higher transistor count in its shading units (6144 versus 1792), more texture mapping units (192 versus 112), and more render output units (96 versus 64). The data indicates a peak FP32 throughput of 24.58 TFLOPS against the AMD part's 17.56 TFLOPS, a difference of roughly 40%. For users building a desktop workstation or a high-end gaming rig where space is not a constraint, the LX 7G100 delivers more compute per board.

The AMD Steam Machine GPU, conversely, is designed for constrained environments. Its dimensions (156 mm length, 152 mm height, 162 mm width) and its 110 W TDP make it a compact solution, whereas the Lisuan Tech card is 294 mm long, 120 mm tall, and 49 mm wide with a 225 W TDP. The AMD part does not require external power connectors, while the LX 7G100 uses a single 8-pin connector. The data shows that the AMD option is the only one that fits into a small form factor console-style chassis without a separate power cable, making it the correct pick for a Valve-style steam machine build.

Benchmark results are empty in the database, so the verdict rests on the specification sheet. The Lisuan Tech LX 7G100 is for the builder who prioritizes absolute throughput in an open-air test bench or a full tower case. The AMD Steam Machine GPU is for the builder who needs a self-contained, low-profile solution with adequate performance for 1080p or 1440p gaming, as its 8 GB memory and 288.0 GB/s bandwidth are sufficient for those resolutions. The 50th percentile ranking for both parts in the database indicates they sit at the median of all recorded GPUs, meaning neither is an outlier at the top or bottom of the field.

Architecture Differences

The two GPUs share a foundry and process node: both are built by TSMC on a 6 nm process. The similarity ends there, as the underlying architectures diverge completely.

The AMD Steam Machine GPU uses the RDNA 3.0 architecture, specifically the Navi 33 chip under the codename "Hotpink Bonefish". This is a console-class GPU from the Valve generation, and its architecture is a direct descendant of AMD's gaming-focused design. The Navi 33 die measures 204 mm² and packs 13,300 million transistors, yielding a transistor density of 65.2 million per square millimeter. The RDNA 3.0 architecture is designed for balanced gaming workloads, with 28 dedicated ray tracing cores and a 1:1 FP16 to FP32 ratio, meaning the FP16 throughput matches the FP32 figure at 17.56 TFLOPS.

The Lisuan Tech LX 7G100 uses a completely different architecture called "TrueGPU", built around the 7G106 chip from the 7G100 generation. The database does not record the die size, transistor count, or transistor density for this part, so those figures are unavailable. What the data does show is a much larger compute configuration: 6144 shading units, 192 TMUs, and 96 ROPs. The FP16 throughput is listed at 49.15 TFLOPS with a 2:1 ratio, meaning the FP16 rate is exactly double the FP32 rate of 24.58 TFLOPS. This is a fundamentally different design philosophy, prioritizing raw parallel throughput over the gaming-centric feature set of the RDNA 3.0 part.

Feature support differences are notable. The AMD GPU supports Vulkan 1.4, while the Lisuan Tech part supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD part has 28 ray tracing cores, while the LX 7G100 lists no ray tracing cores in the recorded data, suggesting that ray tracing acceleration is not a focus for the TrueGPU architecture. The AMD GPU's display outputs are 1x HDMI 2.1a and 1x DisplayPort 2.1, whereas the LX 7G100 provides 4x DisplayPort 1.4a, which is a significant difference for multi-monitor setups.

The memory configuration also differs architecturally. The AMD part uses 8 GB of GDDR6 on a 128-bit bus, while the LX 7G100 uses 12 GB of GDDR6 on a 192-bit bus. Both run the same memory clock of 2250 MHz with 18 Gbps effective data rate, but the wider bus on the Lisuan Tech part delivers 432.0 GB/s versus the AMD part's 288.0 GB/s.

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either GPU, and the head-to-head benchmark array is empty. The nearest rivals list is also empty for both parts. As such, there are no direct performance measurements to compare, and the analysis must rely entirely on the specification-derived rates.

The pixel rate is a derived spec that indicates the maximum fill rate. The LX 7G100 achieves 192.0 GPixel/s, which is 35.2 GPixel/s higher than the AMD Steam Machine GPU's 156.8 GPixel/s. This is a 22.4% advantage for the Lisuan Tech part, driven by its larger ROP count of 96 versus 64.

The texture rate shows a larger gap. The LX 7G100 delivers 384.0 GTexel/s, while the AMD part delivers 274.4 GTexel/s. The difference is 109.6 GTexel/s, which is a 39.9% advantage for the Lisuan Tech card. This is directly attributable to the TMU count: 192 versus 112.

The FP32 compute rate is 24.58 TFLOPS for the LX 7G100 versus 17.56 TFLOPS for the AMD part. The margin is 7.02 TFLOPS, or exactly 40%. This is the most significant single-specification gap between the two cards and indicates that the LX 7G100 will handle compute-heavy workloads, such as physics simulations or rendering, with proportionally more throughput.

The memory bandwidth advantage is similarly pronounced. The LX 7G100's 432.0 GB/s is 144.0 GB/s higher than the AMD card's 288.0 GB/s, a 50% improvement. With 12 GB versus 8 GB of memory, the Lisuan Tech card also has 50% more capacity, allowing it to hold larger textures and datasets without spilling to system memory.

The AMD part does hold one advantage in the recorded data: its FP16 throughput matches its FP32 at 17.56 TFLOPS, while the LX 7G100's FP16 rate is 49.15 TFLOPS, which is 2.0 times its FP32 rate. For workloads that use FP16 math, the Lisuan Tech card is much faster, but the AMD card's 1:1 ratio is unusual and may indicate a different approach to mixed-precision workloads.

Where Each One Wins

The Lisuan Tech LX 7G100 wins in every recorded performance specification. Its FP32 rate of 24.58 TFLOPS is 40% higher than the AMD part's 17.56 TFLOPS. The texture rate of 384.0 GTexel/s is 39.9% higher than 274.4 GTexel/s. The pixel rate of 192.0 GPixel/s is 22.4% higher than 156.8 GPixel/s. Memory bandwidth of 432.0 GB/s is 50% higher than 288.0 GB/s, and the 12 GB capacity is 50% larger than 8 GB. For any workload that scales with compute units, texture fetch, or memory throughput, the LX 7G100 is the faster card. Its 4x DisplayPort 1.4a outputs also make it the clear choice for multi-monitor productivity setups or surround gaming configurations.

The AMD Steam Machine GPU wins in the integration category. Its 110 W TDP is less than half of the LX 7G100's 225 W, and it requires no external power connector, which simplifies cabling in a compact chassis. The dimensions are dramatically different: the AMD part is 156 mm long and 152 mm tall, which is nearly a square footprint, while the LX 7G100 is 294 mm long and only 49 mm wide, a typical full-length expansion card. The AMD card also has a newer Vulkan version (1.4 versus 1.3) and includes 28 ray tracing cores, which the LX 7G100 lacks. The display outputs include an HDMI 2.1a port, which is useful for connecting to modern televisions, whereas the LX 7G100 only offers DisplayPort connections. The AMD part's release date is 2026-06-28, which is 11 days later than the LX 7G100's 2026-06-17 release.

The physical design of the AMD card, with a 162 mm width and no power connector, indicates it is intended for a console-style enclosure where the card sits flat or in a custom orientation. The LX 7G100, with its dual-slot width and PCIe 4.0 x16 interface, is a conventional desktop card designed for a standard motherboard slot. Builders with a traditional ATX or micro-ATX case should choose the LX 7G100 for its superior specifications, while builders assembling a compact console-like system have no alternative in this comparison other than the AMD Steam Machine GPU, which offers adequate performance with a 50th percentile ranking in the database.
