AMD Radeon PRO W7800 vs Lisuan Tech LX MAX Comparison

The Verdict

The AMD Radeon PRO W7800 is the clear choice for compute-heavy professional workloads. Its recorded benchmark data shows an average score of 164,894, placing it in the 97th percentile of all GPUs in the database. The Lisuan Tech LX MAX, by contrast, has no recorded benchmark scores, sits at the 50th percentile, and carries an average score of zero. The W7800 also has a fully documented specification sheet with confirmed performance metrics, while the LX MAX omits several key fields including core clocks, transistor count, die size, and ray tracing core count.

The W7800 suits users who need 32 GB of memory, high FP32 throughput at 45.25 TFLOPS, and proven performance against established workstation rivals. The LX MAX targets those who prioritize a smaller physical footprint, a single 16-pin power connector, and four DisplayPort outputs. Its 6 nm process node and 12 GB memory configuration indicate a more modest compute envelope, with FP32 at 24.58 TFLOPS, roughly half the W7800's throughput.

Architecture differences point to different design philosophies. The W7800 uses RDNA 3.0 with 70 dedicated ray tracing cores and a 5 nm process. The LX MAX uses a TrueGPU architecture on a 6 nm node with no listed ray tracing cores. The data suggests the W7800 is a proven quantity, while the LX MAX remains an unverified entry whose actual performance cannot be confirmed from current database records.

Architecture Differences

The AMD Radeon PRO W7800 uses the Navi 31 chip, codenamed Plum Bonito, built on RDNA 3.0 architecture. It is manufactured by TSMC on a 5 nm process with 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The Lisuan Tech LX MAX uses the 7G106 chip with a TrueGPU architecture, also fabricated by TSMC but on a 6 nm process. Its transistor count and die size are listed as unknown, and no transistor density is recorded.

The W7800 features 4,480 shading units, 280 texture mapping units, and 128 raster operation units. It includes 70 ray tracing cores, a feature absent from the LX MAX specification. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. Despite having fewer shading units, the W7800 achieves higher pixel and texture rates: 323.2 GPixel/s and 707.0 GTexel/s versus 192.0 GPixel/s and 384.0 GTexel/s for the LX MAX.

Clock behavior differs significantly. The W7800 has a base clock of 1895 MHz and a boost clock of 2525 MHz. The LX MAX has no base or boost clock recorded. Memory clocks are identical at 2250 MHz with 18 Gbps effective data rate, but the memory subsystems diverge elsewhere. The W7800 uses 32 GB of GDDR6 on a 256-bit bus for 576.0 GB/s bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus for 432.0 GB/s.

Both cards support PCIe 4.0 x16 and DirectX 12 Ultimate (12_2) plus OpenGL 4.6. They differ in Vulkan support: the W7800 supports Vulkan 1.4 while the LX MAX supports Vulkan 1.3. Display outputs also differ, with the W7800 offering three DisplayPort 2.1 outputs plus one mini-DisplayPort 2.1, while the LX MAX provides four DisplayPort 1.4a outputs.

Where Each One Wins

The W7800 wins decisively in raw compute throughput. Its FP32 performance of 45.25 TFLOPS nearly doubles the LX MAX's 24.58 TFLOPS. FP16 performance follows the same pattern: 90.50 TFLOPS (2:1) versus 49.15 TFLOPS (2:1). Memory capacity is another clear victory, with 32 GB versus 12 GB, and memory bandwidth favors the W7800 at 576.0 GB/s versus 432.0 GB/s.

The W7800 also wins on interface support. It offers Vulkan 1.4 compared to Vulkan 1.3 on the LX MAX, and its DisplayPort 2.1 outputs support higher display bandwidth than the LX MAX's DisplayPort 1.4a connections. The W7800's ray tracing cores provide hardware acceleration that the LX MAX lacks entirely.

The LX MAX wins on physical dimensions and power delivery. It measures 248 mm in length, 118 mm in height, and 48 mm in width, making it shorter but taller and thicker than the W7800's 280 mm by 110 mm by 40 mm. The LX MAX uses a single 16-pin power connector and has a 225 W TDP with a 550 W suggested PSU. The W7800 requires two 8-pin connectors, draws 260 W, and needs a 600 W PSU.

The LX MAX offers four DisplayPort outputs versus the W7800's three plus one mini-DisplayPort, which may suit multi-monitor setups with standard connectors. The LX MAX also has more shading units (6,144 versus 4,480), though this does not translate to higher throughput in the recorded data.

Head-to-Head Benchmarks

The head-to-head benchmark data contains no direct comparison tests between these two cards. However, the W7800's individual benchmark results provide context. In Geekbench OpenCL, the W7800 scores 154,366. In Geekbench Vulkan, it scores 175,422. These combine to an average benchmark score of 164,894.

The W7800's nearest rivals in the database quantify its standing. The NVIDIA RTX A5500 has an average score of 165,217, which is 0.2% higher than the W7800. The NVIDIA RTX 4500 Ada Generation scores 166,094, 0.7% higher. The AMD Radeon Pro W6900X scores 168,574, 2.2% higher. The W7800 outperforms the NVIDIA A100 PCIe 40 GB, which scores 162,504, by 1.5%.

The LX MAX has no comparable benchmark data. Its average score is zero, and its nearest rivals list is empty. This absence of recorded performance means the database cannot place it relative to the W7800 or any other GPU with confidence.

The FP32 compute gap is the most significant measured difference. At 45.25 TFLOPS, the W7800 delivers 20.67 TFLOPS more than the LX MAX's 24.58 TFLOPS. FP16 follows the same ratio, with the W7800 at 90.50 TFLOPS versus 49.15 TFLOPS. Pixel fill rate favors the W7800 by 131.2 GPixel/s (323.2 versus 192.0), and texture fill rate favors it by 323.0 GTexel/s (707.0 versus 384.0).

Bandwidth differences are also substantial. The W7800's 576.0 GB/s exceeds the LX MAX's 432.0 GB/s by 144.0 GB/s, a 33% advantage. This bandwidth advantage, combined with double the memory capacity, positions the W7800 for large datasets and high-resolution textures. The LX MAX's 6,144 shading units versus 4,480 on the W7800 does not overcome the clock and architecture advantages of the W7800, as reflected in the throughput figures.

The W7800 was released on April 12, 2023, with a launch MSRP of 2,499 USD. The LX MAX has a release date of March 16, 2026, and no launch MSRP recorded. Both are listed as Active in production status. The W7800's predecessor is the Radeon Pro Vega; the LX MAX has no predecessor listed. Both cards are dual-slot designs with no successors recorded.

The W7800's memory clock matches the LX MAX at 2250 MHz with 18 Gbps effective, but the wider 256-bit bus and double capacity give it the bandwidth and capacity advantage. The LX MAX's 6 nm process may offer different efficiency characteristics, but without clock speed data or benchmark scores, the database cannot quantify any such advantage.
