NVIDIA L20 vs Lisuan Tech LX PRO Comparison

NVIDIA L20 vs Lisuan Tech LX PRO

Head-to-Head Benchmarks

The recorded data shows a stark contrast in benchmark coverage between these two accelerators. The NVIDIA L20 has two database benchmark entries, while the Lisuan Tech LX PRO has no recorded benchmark scores, leaving its average benchmark score at zero. This makes a direct numerical comparison impossible for most workloads, but the available data still provides meaningful signals.

The NVIDIA L20 scores 274,276 points in Geekbench OpenCL and 228,018 points in Geekbench Vulkan. Its average benchmark score across all recorded tests is 251,147. This places the L20 in the 99th percentile of all GPUs in the database, indicating it outperforms 99 percent of recorded graphics processors. The Lisuan Tech LX PRO sits at the 50th percentile with no recorded benchmark data, which reflects a database position based on its specifications rather than measured performance.

The nearest rival data for the NVIDIA L20 provides additional context. The L20 delivers an average score 11.6 percent higher than the NVIDIA PG506-232, which records an average of 225,124 points. Against the AMD Radeon PRO W7900D, the L20 is 14.2 percent ahead of that card's 219,827 average. However, the L20 trails higher-tier NVIDIA workstation parts. The NVIDIA L40 scores 284,111 on average, which is 11.6 percent higher than the L20, and the NVIDIA RTX 6000 Ada Generation records 287,237 points, putting it 12.6 percent ahead.

Since the LX PRO has no benchmark entries, the head-to-head comparison relies on specification-derived expectations. The L20's 59.35 TFLOPS FP32 throughput is more than double the LX PRO's 24.58 TFLOPS. In FP16 compute, the L20 delivers 59.35 TFLOPS at a 1:1 ratio, while the LX PRO reaches 49.15 TFLOPS at a 2:1 ratio. Texture rate favors the L20 at 927.4 GTexel/s versus 384.0 GTexel/s for the LX PRO. Pixel rate also favors NVIDIA, with 322.6 GPixel/s against 192.0 GPixel/s.

The memory subsystem heavily favors the L20. It carries 48 GB of GDDR6 across a 384-bit bus, yielding 864.0 GB/s of bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, producing 432.0 GB/s, exactly half the bandwidth. Both cards run their memory at 2250 MHz with 18 Gbps effective data rate, so the difference comes entirely from bus width and capacity.

In the absence of LX PRO benchmark scores, the database shows the L20 as the only one of the two with measured performance data. The L20's 99th percentile ranking confirms it competes at the top of the recorded GPU field, while the LX PRO's 50th percentile with no scores leaves its real-world position undetermined.

Architecture Differences

The NVIDIA L20 uses the AD102 chip built on the Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. The die measures 609 mm² and contains 76,300 million transistors, giving a transistor density of 125.3 million per mm². The Lisuan Tech LX PRO uses the 7G105 chip on the TrueGPU architecture, also produced by TSMC but on a 6 nm process. The LX PRO's transistor count and die size are listed as unknown in the database, and no density figure is recorded.

The L20 belongs to the Server Ada generation, with its predecessor listed as Server Ampere and its successor as Server Hopper. The LX PRO belongs to the 7G100 generation, with no predecessor or successor recorded. Both cards are currently marked as Active in production status.

The L20 includes 11,776 shading units, 368 texture mapping units, and 128 raster output pipelines. It also carries 92 RT cores and 368 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, but no RT core or tensor core counts are recorded in the database. The absence of RT and tensor core data for the LX PRO suggests either the hardware lacks these units or the information is simply not available.

The L20's memory clock runs at 2250 MHz with 18 Gbps effective throughput. The LX PRO memory clock matches this exactly at 2250 MHz and 18 Gbps effective. Both use GDDR6 memory, but the L20 doubles the LX PRO in capacity and bandwidth as described in the benchmark section.

API support differs slightly. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The L20 supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. Display outputs are identical at 4x DisplayPort 1.4a for both.

The power delivery configurations share the same 1x 16-pin power connector and dual-slot form factor. The L20 has a 275 W TDP with a suggested power supply of 600 W. The LX PRO draws 225 W with a suggested power supply of 550 W. Physical dimensions differ: the L20 measures 267 mm in length (10.5 inches) and 111 mm in height (4.4 inches), while the LX PRO is 248 mm long (9.8 inches), 118 mm tall (4.6 inches), and 48 mm wide (1.9 inches). The L20's width is not recorded.

Where Each One Wins

The NVIDIA L20 wins in every category where measured data exists. Its 251,147 average benchmark score versus the LX PRO's zero recorded score gives it the clear performance advantage in the database. The L20 also holds the 99th percentile ranking, while the LX PRO sits at the 50th percentile.

For compute-heavy workloads, the L20's FP32 output of 59.35 TFLOPS positions it well above the LX PRO's 24.58 TFLOPS. This suggests the L20 handles single-precision floating-point tasks with over twice the throughput. The FP16 comparison is closer but still favors NVIDIA: the L20's 59.35 TFLOPS at 1:1 ratio versus the LX PRO's 49.15 TFLOPS at 2:1 ratio. The LX PRO's 2:1 FP16 ratio indicates it can double its FP16 rate relative to FP32, a common feature for AI inference workloads, but even at that boosted rate it stays behind the L20.

Memory-intensive applications clearly favor the L20. Its 48 GB capacity and 864.0 GB/s bandwidth support large datasets and high-throughput streaming. The LX PRO's 24 GB and 432.0 GB/s can handle smaller working sets but will hit capacity and bandwidth limits sooner. The L20's 384-bit bus versus the LX PRO's 192-bit bus is the primary driver of this bandwidth gap.

The L20's 92 RT cores give it a dedicated hardware path for ray tracing workloads. The LX PRO has no RT core count recorded, so its ray tracing capability is either absent or unverified. Tensor cores on the L20 number 368, providing acceleration for matrix operations common in deep learning. The LX PRO again has no tensor core data recorded.

For rasterization throughput, the L20's 322.6 GPixel/s pixel rate and 927.4 GTexel/s texture rate dwarf the LX PRO's 192.0 GPixel/s and 384.0 GTexel/s. This implies the L20 handles higher resolution rendering and more textured scenes with greater headroom.

The LX PRO does have some advantages in the specification sheet. Its 225 W TDP is 50 W lower than the L20's 275 W, suggesting lower power consumption. Its suggested power supply of 550 W is 50 W lower than the L20's 600 W recommendation. The LX PRO is also shorter at 248 mm versus 267 mm, which may help in space-constrained chassis. Its width of 48 mm is recorded, while the L20's width is not, but both are dual-slot cards.

The LX PRO's Vulkan 1.3 support trails the L20's Vulkan 1.4, but both are recent API versions. The LX PRO's release date of March 2026 is later than the L20's November 2023 release, making it the newer product by the database's recorded dates.

Clock speeds show a significant gap. The L20 has a base clock of 1440 MHz and a boost clock of 2520 MHz. The LX PRO has no base or boost clock recorded. Both memory clocks are identical at 2250 MHz.

Performance rates favor the L20 in all categories: 322.6 GPixel/s versus 192.0 GPixel/s pixel rate, 927.4 GTexel/s versus 384.0 GTexel/s texture rate, 59.35 TFLOPS versus 24.58 TFLOPS FP32, and 59.35 TFLOPS versus 49.15 TFLOPS FP16. The FP16 ratio differs, with the L20 at 1:1 and the LX PRO at 2:1.

Power specifications show the LX PRO draws less. The L20 has a 275 W TDP and 600 W suggested PSU. The LX PRO has a 225 W TDP and 550 W suggested PSU. Both use one 16-pin power connector and dual-slot cooling.
