AMD Radeon RX 7800 XT vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The recorded data presents an unusual comparison because the two cards occupy different positions in the database. The AMD Radeon RX 7800 XT has a full set of benchmark results across ten tests, while the Lisuan Tech LX MAX has no recorded benchmark scores at all. The RX 7800 XT therefore wins every measurable benchmark category by default, but that does not mean the comparison is meaningless. The LX MAX still has a complete hardware specification, and that specification tells a different story about where it would likely excel.

The RX 7800 XT wins in raw rasterization throughput. Its FP32 compute of 37.32 TFLOPS is substantially higher than the LX MAX's 24.58 TFLOPS, a gap of roughly 52 percent in favor of the AMD card. The texture rate also favors AMD, with 583.2 GTexel/s versus 384.0 GTexel/s for the LX MAX, a 52 percent advantage. The pixel rate follows the same pattern: 233.3 GPixel/s for the RX 7800 XT against 192.0 GPixel/s for the Lisuan part. These are the numbers that drive traditional gaming performance, and they all point to the AMD card being the stronger choice for conventional frame rendering.

The LX MAX wins in one specific compute area, however. Its FP16 throughput is 49.15 TFLOPS, which is 32 percent higher than its own FP32 rate and 32 percent higher than the RX 7800 XT's FP16 figure of 37.32 TFLOPS. The RX 7800 XT runs FP16 at a 1:1 ratio with FP32, meaning it does not gain any throughput when switching to half precision. The LX MAX runs FP16 at a 2:1 ratio, so it effectively doubles its compute rate in half-precision workloads. This indicates the Lisuan card is designed with a different compute philosophy, one that could be advantageous in AI inference, certain scientific workloads, or any application that can exploit FP16 arithmetic.

The memory configuration also splits the two cards. The RX 7800 XT has 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The LX MAX has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The AMD card offers 33 percent more memory capacity and 44 percent more bandwidth. For large textures, high-resolution rendering, or memory-hungry workloads, the RX 7800 XT has a clear edge. The LX MAX cannot match that capacity, but its smaller memory footprint also contributes to a lower power draw of 225 W versus 263 W for the AMD card.

Architecture Differences

The two cards come from completely different architectural lineages. The AMD Radeon RX 7800 XT uses the Navi 32 chip built on RDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It belongs to the Radeon RX 7000 series and the Navi III generation, with the codename Wheat Nas. The chip contains 28,100 million transistors on a 346 mm² die, giving it a transistor density of 81.2M per mm².

The Lisuan Tech LX MAX uses the 7G106 chip built on TrueGPU architecture, manufactured on a 6 nm process also at TSMC. It belongs to the 7G100 generation. The database records the transistor count and die size as unknown, so no density figure is available. The manufacturing process difference is notable: 5 nm versus 6 nm. The smaller node typically allows for higher transistor density and better power efficiency, but the LX MAX compensates with a completely different compute structure.

The shading unit counts tell the more interesting story. The RX 7800 XT has 3840 shading units, 240 texture mapping units, and 96 render output units. The LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs. The Lisuan card has 60 percent more shading units than the AMD card, but 20 percent fewer texture units. This is a fundamental architectural divergence. The LX MAX appears to be built around a massively parallel shading array that can feed FP16 compute very effectively, while the AMD card uses a more balanced configuration with fewer, more capable units.

The RX 7800 XT also includes 60 dedicated ray tracing cores, a feature the LX MAX does not list at all. Neither card has tensor cores. The ray tracing hardware on the AMD card supports DirectX 12 Ultimate with the 12_2 feature level, and both cards support DirectX 12 Ultimate and OpenGL 4.6. The Vulkan support differs slightly: the RX 7800 XT supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3.

Memory architecture differs as well. The RX 7800 XT operates its GDDR6 at 2438 MHz with 19.5 Gbps effective data rate. The LX MAX operates at 2250 MHz with 18 Gbps effective. The AMD card also has a wider 256-bit memory bus versus the LX MAX's 192-bit bus. Both cards use GDDR6 memory, but the RX 7800 XT has more of it and moves it faster.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, and the LX MAX has no individual benchmark scores recorded. The wins counter shows zero for both cards. This means the direct comparison must rely on the RX 7800 XT's own benchmark results and the architectural specifications of the LX MAX.

The RX 7800 XT's benchmark data shows a mixed profile across different test types. In PassMark G3D, it scores 24,176, which is its strongest result relative to other GPUs. Its PassMark GPU Compute score is 13,473. In Geekbench Vulkan, it reaches 54,228, while its Geekbench OpenCL score is 18,290. The 3DMark Steel Nomad DX12 test gives it 4,157. The PassMark DirectX 9 score is 304, DirectX 11 is 249, DirectX 10 is 121, and DirectX 12 is 93. The PassMark G2D score is 1,177.

The average benchmark score for the RX 7800 XT is 11,627, which places it at the 51st percentile among all GPUs in the database. Its nearest rivals are revealing. The NVIDIA GeForce GTX 1660 scores 11,680 on average, which is 0.5 percent higher than the RX 7800 XT. The AMD Radeon Pro 5500M scores 11,528, which is 0.9 percent lower. The NVIDIA Tesla K20c scores 11,479, which is 1.3 percent lower. The AMD Radeon RX 6500 XT scores 11,842, which is 1.8 percent higher.

These nearest rival results indicate that the RX 7800 XT's average benchmark score sits in a very tight cluster. The spread between the lowest and highest rival is only about 3 percent. This is a narrow performance band, and the RX 7800 XT sits almost exactly in the middle of it. The benchmark data suggests the card performs consistently across different test methodologies, with no single test showing an extreme outlier.

The LX MAX has no benchmark data to compare directly. Its average benchmark score is recorded as zero, and its percentile is 50, which appears to be a placeholder rather than a measured result. The database shows no nearest rivals for the Lisuan card, and no head-to-head results exist. The comparison must therefore be drawn from the specification sheet, which shows the LX MAX would likely trail in rasterization but could compete or lead in FP16 compute workloads.

The Verdict

The data supports a clear division of use cases. For traditional gaming and rasterized rendering, the AMD Radeon RX 7800 XT is the stronger card. Its FP32 throughput of 37.32 TFLOPS, texture rate of 583.2 GTexel/s, and pixel rate of 233.3 GPixel/s all exceed the LX MAX's corresponding figures by a wide margin. The 16 GB memory capacity and 624.1 GB/s bandwidth also give it a significant advantage for high-resolution textures and memory-intensive scenes. The RX 7800 XT has a measured benchmark profile that places it in the 51st percentile of all GPUs, with an average score of 11,627 across ten tests.

For FP16 compute workloads, the Lisuan Tech LX MAX presents a different value. Its FP16 throughput of 49.15 TFLOPS exceeds the RX 7800 XT's FP16 figure by 32 percent. This is the only specification where the LX MAX leads, and it is a substantial lead. The 6 nm process and 2:1 FP16 ratio indicate the card was designed to accelerate half-precision arithmetic, which is common in machine learning inference, some scientific simulations, and certain media processing tasks. The LX MAX also draws less power at 225 W versus 263 W for the AMD card, and it uses a single 16-pin power connector instead of two 8-pin connectors.

The RX 7800 XT has the advantage of a complete, verified benchmark record. The LX MAX has no recorded test results, so its actual performance remains unmeasured. The database shows the AMD card at the 51st percentile among all GPUs, while the Lisuan card sits at the 50th percentile with no average score. The AMD card has a known release date of September 5, 2023, and a launch MSRP of 499 USD. The LX MAX has a release date of March 16, 2026, and no launch MSRP listed.

The practical choice depends on the workload. The RX 7800 XT is the proven option for gaming, with a full set of DirectX 12, Vulkan, OpenCL, and PassMark results. The LX MAX is a speculative option for FP16-heavy compute, with a hardware design that clearly prioritizes half-precision throughput over traditional rasterization. The card's unknown transistor count and die size, combined with the absence of benchmark data, make it difficult to assess its real-world capabilities. The data shows the RX 7800 XT as the safer, more complete product, while the LX MAX offers a specific architectural strength that could be valuable in the right compute environment.
