Against the AMD Radeon PRO W7900D, the L20 leads by 14.2%, as that card averages 219,827. Moving upward, the NVIDIA L40 averages 284,111, which places it 11.6% ahead of the L20. The NVIDIA RTX 6000 Ada Generation averages 287,237, putting it 12.6% ahead of the L20.

The LX MAX has no benchmark data recorded, so no direct head-to-head numerical comparison can be made. The L20's documented results indicate a GPU operating at a high performance tier, while the LX MAX's percentile standing of 50 with an average score of zero reflects the absence of measured results in the database.

Where Each One Wins

Based on recorded data, the NVIDIA L20 wins in every measurable benchmark category because it is the only unit with benchmark results. The L20 delivers 59.35 TFLOPS of FP32 performance and 59.35 TFLOPS of FP16 performance with a 1:1 ratio. Its shading units number 11,776, supported by 368 texture mapping units and 128 render output units. The pixel rate reaches 322.6 GPixel/s, and the texture rate reaches 927.4 GTexel/s.

The Lisuan Tech LX MAX provides 24.58 TFLOPS of FP32 performance, which is 58.6% lower than the L20's FP32 figure. Its FP16 performance is 49.15 TFLOPS with a 2:1 ratio, meaning the FP16 rate is double its FP32 rate, a different execution pattern than the L20's 1:1 ratio. The LX MAX contains 6,144 shading units, 192 TMUs, and 96 ROPs. Its pixel rate is 192.0 GPixel/s, and its texture rate is 384.0 GTexel/s.

Clock speeds are recorded differently. The L20 has a base clock of 1440 MHz and a boost clock of 2520 MHz. The LX MAX has no base or boost clock values in the database.

The L20's pixel rate is 322.6 GPixel/s, and its texture rate is 927.4 GTexel/s. The LX MAX's pixel rate is 192.0 GPixel/s, and its texture rate is 384.0 GTexel/s. FP32 compute is 59.35 TFLOPS for the L20 and 24.58 TFLOPS for the LX MAX. FP16 compute is 59.35 TFLOPS with a 1:1 ratio for the L20, and 49.15 TFLOPS with a 2:1 ratio for the LX MAX.

Power specifications differ. The L20 has a TDP of 275 W, while the LX MAX has a TDP of 225 W. The L20 suggests a 600 W power supply, and the LX MAX suggests a 550 W power supply. Both use a single 16-pin power connector and are dual-slot cards.

Physical dimensions vary. The L20 is 267 mm (10.5 inches) long and 111 mm (4.4 inches) high. The LX MAX is 248 mm (9.8 inches) long, 118 mm (4.6 inches) high, and 48 mm (1.9 inches) wide.

The bus interface is the same for both: PCIe 4.0 x16. Display outputs are also identical: 4x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the L20 supports Vulkan 1.4 while the LX MAX supports Vulkan 1.3.

Release dates differ considerably. The L20 was released on 2023-11-15, and the LX MAX was released on 2026-03-16. The L20 lists its predecessor as Server Ampere and its successor as Server Hopper, while the LX MAX has no recorded predecessor or successor.

Architecture Differences

The NVIDIA L20 uses the Ada Lovelace architecture on a 5 nm TSMC process with the AD102 chip. This architecture includes 76,300 million transistors on a 609 mm² die, yielding a transistor density of 125.3 million per mm². The L20 is part of the Server Ada generation, designated as Lxx.

The Lisuan Tech LX MAX uses the TrueGPU architecture on a 6 nm TSMC process with the 7G106 chip. Its transistor count and die size are unknown, and it belongs to the 7G100 generation. The LX MAX has no listed RT cores or tensor cores, indicating its architecture does not expose these hardware units in the recorded specifications.

The L20's Ada Lovelace architecture supports a 1:1 FP16 to FP32 ratio, meaning both precision modes execute at the same rate of 59.35 TFLOPS. The LX MAX's TrueGPU architecture uses a 2:1 ratio, where FP16 runs at 49.15 TFLOPS, double its FP32 rate of 24.58 TFLOPS. This indicates different execution unit designs for mixed-precision workloads.

The L20 includes dedicated RT cores and tensor cores, which are absent from the LX MAX's specification sheet. For applications relying on hardware-accelerated ray tracing or tensor operations, the L20 has explicit hardware support, while the LX MAX does not list any such units.

The L20 supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The L20's slightly newer Vulkan version indicates a more recent API implementation, though both cards are current production models.

The L20's transistor density of 125.3 million per mm² reflects its 5 nm process, while the LX MAX's density cannot be calculated because its transistor count and die size are unknown. The 6 nm process for the LX MAX is one node step behind the L20's 5 nm process, though both are fabricated at TSMC.

Memory architecture also differs structurally. The L20 uses a 384-bit memory bus with 48 GB of GDDR6, achieving 864.0 GB/s of bandwidth. The LX MAX uses a 192-bit bus with 12 GB of GDDR6, achieving 432.0 GB/s. The L20's wider bus and larger capacity make it suited for memory-intensive workloads, while the LX MAX's narrower, smaller configuration targets lower memory demands.

The L20's release date of 2023-11-15 places it in the Server Ada generation, with its architecture lineage from Server Ampere to Server Hopper. The LX MAX's release date of 2026-03-16 places it in the 7G100 generation with no recorded predecessor or successor, making its architectural lineage less defined in the database.

Both cards use a dual-slot design with a single 16-pin power connector, and both are active production units. The L20 has a suggested power supply of 600 W, while the LX MAX suggests 550 W, reflecting the L20's higher TDP of 275 W against the LX MAX's 225 W.
