AMD Steam Machine GPU vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The AMD Steam Machine GPU and Lisuan Tech LX PRO occupy very different positions in the database, despite both sitting at the 50th percentile among all GPUs. The recorded data shows no head-to-head benchmark results, and neither card has an average benchmark score, so the comparison must be built from architectural specifications and compute characteristics.

The AMD Steam Machine GPU is a compact console-oriented part. Its 110 W power target, lack of power connectors, and 156 mm length make it a low-profile solution. The Lisuan Tech LX PRO is a larger dual-slot card, 248 mm long, requiring a 1x 16-pin power connector and a 550 W suggested PSU. The data indicates the LX PRO targets a different segment entirely, one where thermal headroom and board space are available.

In raw compute throughput, the LX PRO dominates. It delivers 24.58 TFLOPS FP32 against 17.56 TFLOPS for the AMD part, a 40% advantage. The gap widens in FP16: the LX PRO reaches 49.15 TFLOPS via a 2:1 ratio, while the AMD card sustains 17.56 TFLOPS at a 1:1 ratio. For workloads that exploit FP16 acceleration, the LX PRO is more than 2.8 times faster.

Memory capacity and bandwidth also favor the LX PRO. It carries 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The AMD Steam Machine GPU has 8 GB on a 128-bit bus, producing 288.0 GB/s. The LX PRO provides three times the capacity and 50% more bandwidth. Texture and pixel throughput follow the same pattern: the LX PRO outputs 384.0 GTexel/s and 192.0 GPixel/s, versus 274.4 GTexel/s and 156.8 GPixel/s for the AMD card.

The AMD Steam Machine GPU does hold advantages in specific areas. Its display outputs include HDMI 2.1a and DisplayPort 2.1, whereas the LX PRO provides four DisplayPort 1.4a connections. The AMD card also supports Vulkan 1.4, one revision newer than the LX PRO's Vulkan 1.3. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6 identically.

The power efficiency picture is stark. The AMD Steam Machine GPU achieves 17.56 TFLOPS at 110 W, roughly 0.16 TFLOPS per watt. The LX PRO delivers 24.58 TFLOPS at 225 W, about 0.11 TFLOPS per watt. Neither figure appears in the pack directly, but the ratio of the recorded numbers favors the AMD part. The AMD card also has no power connector requirement, simplifying installation in compact systems.

The AMD Steam Machine GPU is the choice where board footprint, power draw, and modern display connectivity matter. The LX PRO wins wherever memory capacity, FP16 throughput, or raw rasterization performance is the priority. The 8 GB versus 24 GB difference alone shifts the usable workload range substantially, particularly for large datasets or high-resolution texture sets.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Steam Machine GPU uses the Navi 33 chip, built on RDNA 3.0 architecture with the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The Lisuan Tech LX PRO uses the 7G105 chip under a TrueGPU architecture, part of the 7G100 generation.

Both are fabricated on a 6 nm process at TSMC, the only shared foundry detail. The AMD chip integrates 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The LX PRO's transistor count and die size are recorded as unknown, so no density comparison is possible.

The compute pipelines differ significantly. The AMD Steam Machine GPU has 1792 shading units, 112 TMUs, and 64 ROPs. It also includes 28 dedicated ray tracing cores. The LX PRO has no recorded ray tracing cores, but fields 6144 shading units, 192 TMUs, and 96 ROPs. The LX PRO has 3.4 times as many shading units, 1.7 times as many TMUs, and 1.5 times as many ROPs.

Memory architecture diverges as well. The AMD part uses 8 GB GDDR6 at 2250 MHz with an 18 Gbps effective rate on a 128-bit bus. The LX PRO uses 24 GB GDDR6 at the same 2250 MHz and 18 Gbps effective speed, but on a 192-bit bus. The wider bus accounts for the bandwidth difference: 288.0 GB/s versus 432.0 GB/s.

Clock behavior is not directly comparable. The AMD Steam Machine GPU has explicit base (1720 MHz), boost (2450 MHz), and game (2250 MHz) clocks. The LX PRO records no base, boost, or game clocks at all, only the memory clock. The absence of clock data for the LX PRO means the TFLOPS figures must be taken as the sole compute reference.

API support shows small but meaningful differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD card supports Vulkan 1.4, while the LX PRO stops at Vulkan 1.3. Display connectivity also differs: the AMD part offers one HDMI 2.1a and one DisplayPort 2.1, while the LX PRO has four DisplayPort 1.4a outputs, no HDMI.

Physical and electrical specifications reveal different design intents. The AMD Steam Machine GPU is 156 mm long, 152 mm high, and 162 mm wide, with no power connector and a 110 W TDP. The LX PRO is 248 mm long, 118 mm high, and 48 mm wide, dual-slot, with a 1x 16-pin connector and 225 W TDP. The LX PRO also specifies a PCIe 4.0 x16 interface, while the AMD card records no bus interface.

The FP16 execution rate is a key architectural tell. The AMD card runs FP16 at the same rate as FP32, a 1:1 ratio typical of RDNA 3.0 consumer parts. The LX PRO doubles FP32 throughput in FP16, a 2:1 ratio that suggests a compute-oriented design. This difference alone explains why the LX PRO's FP16 figure (49.15 TFLOPS) far exceeds its FP32 figure (24.58 TFLOPS), while the AMD card stays flat at 17.56 TFLOPS in both.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs, so the comparison relies on recorded specification-derived rates and compute figures.

The largest win for the Lisuan Tech LX PRO is in FP16 throughput. The LX PRO reaches 49.15 TFLOPS, more than 2.8 times the AMD Steam Machine GPU's 17.56 TFLOPS. This is the single biggest numerical gap in the entire comparison. The 2:1 FP16 ratio on the LX PRO means any workload using FP16 instructions, common in machine learning inference or certain compute shaders, will see a dramatic advantage.

In FP32, the LX PRO's 24.58 TFLOPS beats the AMD card's 17.56 TFLOPS by 7.02 TFLOPS, a 40% margin. This translates directly to rasterization-heavy workloads where FP32 ALU throughput is the bottleneck. The AMD card's 1792 shading units against 6144 for the LX PRO explains the gap, though the AMD card's higher boost clock of 2450 MHz partially compensates.

Memory bandwidth favors the LX PRO by 144.0 GB/s, or 50%. The 432.0 GB/s versus 288.0 GB/s difference stems from the 192-bit bus versus 128-bit. For texture-heavy scenes or large framebuffers, the extra bandwidth reduces stalls. The LX PRO also has a texture rate of 384.0 GTexel/s, which is 40% higher than the AMD card's 274.4 GTexel/s. Pixel rate is closer: 192.0 GPixel/s versus 156.8 GPixel/s, a 22% advantage for the LX PRO.

The AMD Steam Machine GPU counters in several areas. Its ray tracing hardware, 28 dedicated RT cores, is absent from the LX PRO's specification sheet. Games or applications using DXR or Vulkan ray tracing will run on the AMD card but have no recorded hardware acceleration on the LX PRO. The AMD card also supports Vulkan 1.4, a newer API revision than the LX PRO's Vulkan 1.3, which may enable additional features or optimizations.

Display connectivity is another AMD win. The HDMI 2.1a port supports modern TV features, and DisplayPort 2.1 exceeds the LX PRO's DisplayPort 1.4a standard. For a console-style device connected to a television, the AMD card's output options are more current. The LX PRO's four DisplayPort outputs suit multi-monitor setups but lack HDMI compatibility.

Power efficiency heavily favors the AMD card. At 110 W, it produces 17.56 TFLOPS FP32. The LX PRO at 225 W produces 24.58 TFLOPS. Scaling the AMD card's efficiency to 225 W would yield roughly 35.9 TFLOPS, far above the LX PRO's actual figure. The AMD card also requires no external power connector, simplifying installation in small form factor systems.

The release dates show the LX PRO arrived earlier, on 2026-03-16, while the AMD Steam Machine GPU followed on 2026-06-28. Both remain in Active production status. The AMD card's 156 mm length and 162 mm width make it suitable for compact enclosures; the LX PRO's 248 mm length and dual-slot design require a standard ATX case. The physical dimensions, power draw, and connector requirements point to mutually exclusive use cases: the AMD card for integrated console-style builds, the LX PRO for conventional desktop towers where space and power budget are secondary.
