AMD Xbox Series X 6nm GPU vs Lisuan Tech LX MAX Comparison

The Verdict

The recorded data presents two 6 nm TSMC GPUs with identical DirectX 12 Ultimate support, but the Lisuan Tech LX MAX holds a clear positional advantage across raw compute, memory capacity, and output configurability. The AMD Xbox Series X 6nm GPU, built on the Scarlett 6nm chip with RDNA 2.0 architecture, delivers a more console-oriented feature set with a single HDMI 2.1 output and a 200 W power target. The LX MAX, using the 7G106 chip with TrueGPU architecture, offers higher shading unit counts, double the FP32 throughput, and a larger 12 GB memory pool, while consuming 225 W.

Benchmark results indicate the LX MAX is the stronger choice for scenarios demanding raw throughput and sustained compute workloads. Its 24.58 TFLOPS FP32 rating and 49.15 TFLOPS FP16 rating (2:1 ratio) position it well ahead of the AMD part, which records 12.15 TFLOPS FP32 and 24.29 TFLOPS FP16. The LX MAX also provides four DisplayPort 1.4a outputs versus a single HDMI 2.1 on the AMD GPU, which matters for multi-display setups.

The AMD Xbox Series X 6nm GPU retains relevance in specific contexts. Its 560.0 GB/s memory bandwidth exceeds the LX MAX's 432.0 GB/s, and its 320 bit memory bus is wider than the 192 bit bus on the LX MAX. That bandwidth advantage can benefit memory-bound workloads despite the lower compute ceiling. The AMD part also has a shorter physical footprint in one dimension: 301 mm length versus 248 mm for the LX MAX, though the LX MAX is narrower and shorter in height and width.

The database shows both GPUs at the 50th percentile versus all GPUs, with no benchmark scores recorded and no nearest rivals defined. That means the comparison rests entirely on architectural and specification data, not measured performance results. Users should interpret the compute and memory figures as design capabilities, not verified outcomes.

For pure compute density, the LX MAX wins decisively. For memory bandwidth efficiency, the AMD part wins. The LX MAX uses a 1x 16-pin power connector with a suggested 550 W PSU, while the AMD GPU lists no power connector or suggested PSU in the database. The LX MAX's dual-slot cooler and PCIe 4.0 x16 interface also indicate a desktop expansion card form factor, whereas the AMD part's dimensions and single HDMI output suggest an integrated console solution.

Architecture Differences

The two GPUs diverge fundamentally at the chip and architecture level. The AMD Xbox Series X 6nm GPU uses the Scarlett 6nm chip built on RDNA 2.0, a console-specific design from Microsoft's generation. The Lisuan Tech LX MAX uses the 7G106 chip with TrueGPU architecture, belonging to the 7G100 generation. Both are fabricated on a 6 nm process at TSMC, but the transistor counts differ: the AMD chip contains 15,300 million transistors, while the LX MAX's transistor count is unknown in the database.

Shading unit counts show a major split. The LX MAX carries 6,144 shading units, nearly double the AMD part's 3,328 units. Texture mapping units are closer: 192 on the LX MAX versus 208 on the AMD GPU. Render output units favor the LX MAX at 96 versus 64 on the AMD part. The LX MAX also leads in pixel rate at 192.0 GPixel/s versus 116.8 GPixel/s, and in texture rate at 384.0 GTexel/s versus 379.6 GTexel/s, a narrow margin despite the shading unit gap.

Memory architecture differs significantly. The AMD GPU uses 10 GB of GDDR6 on a 320 bit bus, achieving 560.0 GB/s bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192 bit bus, achieving 432.0 GB/s bandwidth. The LX MAX runs its memory at 2250 MHz (18 Gbps effective), while the AMD part runs at 1750 MHz (14 Gbps effective). The AMD GPU's wider bus compensates for the lower clock, yielding higher total bandwidth.

Compute throughput is the largest architectural gap. The LX MAX delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16, exactly double the AMD GPU's 12.15 TFLOPS FP32 and 24.29 TFLOPS FP16. Both list FP16 at a 2:1 ratio, so the doubling is consistent across precision formats.

API support shows parity on DirectX 12 Ultimate (12_2) and OpenGL 4.6, but Vulkan support differs: the LX MAX lists Vulkan 1.3, while the AMD GPU lists Vulkan 1.2. Display outputs also diverge: the AMD part has a single HDMI 2.1, the LX MAX has four DisplayPort 1.4a ports. The LX MAX specifies a dual-slot form factor, a 16-pin power connector, and a 550 W suggested PSU; the AMD GPU lists no slot width, power connector, or PSU guidance.

Release dates place the AMD GPU in October 2024 with a launch MSRP of 599 USD, while the LX MAX appears in March 2026 with no launch MSRP recorded. The AMD GPU's dimensions are 301 mm length, 151 mm height, and 151 mm width. The LX MAX measures 248 mm length, 118 mm height, and 48 mm width, making it shorter, lower, and much thinner.

Head-to-Head Benchmarks

No recorded benchmark scores exist for either GPU in the database. Both entries show empty benchmark arrays, zero wins, and an average benchmark score of zero. The percentile versus all GPUs is identical at 50 for both, indicating no performance ranking has been established through measured tests. The head-to-head benchmark list is also empty, so no direct comparison data exists.

The analysis must therefore rely on specification-derived capabilities. The LX MAX's FP32 throughput of 24.58 TFLOPS is 102% higher than the AMD GPU's 12.15 TFLOPS, a twofold advantage in raw shader compute. FP16 follows the same pattern: 49.15 TFLOPS versus 24.29 TFLOPS, again a 2:1 ratio. Pixel rate on the LX MAX (192.0 GPixel/s) exceeds the AMD part (116.8 GPixel/s) by 64%, driven by the higher ROP count. Texture rate is nearly identical: 384.0 GTexel/s versus 379.6 GTexel/s, a 1.2% difference in favor of the LX MAX.

Memory bandwidth tells the opposite story. The AMD GPU's 560.0 GB/s is 29.6% higher than the LX MAX's 432.0 GB/s. That bandwidth gap, combined with the 320 bit bus width versus 192 bit, suggests the AMD part may handle large data transfers more efficiently despite lower compute. The LX MAX compensates with 20% more memory capacity (12 GB versus 10 GB), which benefits workloads that exceed the AMD GPU's frame buffer.

The power envelope is close: 200 W for the AMD GPU versus 225 W for the LX MAX. The LX MAX consumes 12.5% more power while delivering roughly double the FP32 throughput, indicating a significantly better compute-per-watt ratio on paper. The AMD GPU's lower power draw may suit constrained thermal environments, but the LX MAX's higher ceiling offers more headroom for sustained compute.

Vulkan support favors the LX MAX with version 1.3 versus 1.2 on the AMD GPU, which may matter for cross-platform applications using newer Vulkan extensions. Both support DirectX 12 Ultimate (12_2), so modern DirectX features are equally accessible.
