NVIDIA RTX PRO 5000 Blackwell vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The data splits these two cards cleanly by workload category. The NVIDIA RTX PRO 5000 Blackwell is the clear winner in every recorded benchmark, but the Lisuan Tech LX PRO has a structural advantage in raw FP16 throughput relative to its FP32 output. The NVIDIA card reaches the 98th percentile among all GPUs in the database, while the LX PRO sits at the 50th percentile. That percentile gap alone tells the story: the RTX PRO 5000 is a top-tier workstation accelerator, while the LX PRO is a mid-pack performer.

For synthetic DirectX 12 workloads, the RTX PRO 5000 delivers a 3DMark Steel Nomad score of 9,579.5. The LX PRO has no recorded score in that test, so the comparison is one-sided. For compute-oriented OpenCL and Vulkan loads, the RTX PRO 5000 posts 254,116 and 282,631 respectively. The LX PRO has no benchmark entries at all in the database, making any head-to-head comparison quantitative only on the NVIDIA side.

Where the LX PRO wins is in FP16 compute ratio. Its FP16 output is 49.15 TFLOPS at a 2:1 ratio to its FP32 figure of 24.58 TFLOPS. The RTX PRO 5000 runs FP16 at 66.94 TFLOPS with a 1:1 ratio to FP32. This means the LX PRO doubles its throughput when moving from FP32 to FP16, while the NVIDIA card maintains parity. For workloads that can exploit FP16 arithmetic, the LX PRO's relative uplift is proportionally larger, even though the absolute FP16 number remains lower.

The NVIDIA card also wins on memory capacity and bandwidth. With 48 GB of GDDR7 on a 384-bit bus, it reaches 1.34 TB/s. The LX PRO offers 24 GB of GDDR6 on a 192-bit bus for 432.0 GB/s. That is less than one-third the bandwidth and half the capacity. For large datasets or high-resolution rendering, the RTX PRO 5000 has a decisive edge.

Architecture Differences

The two cards come from different architectural lineages. The RTX PRO 5000 uses NVIDIA's Blackwell 2.0 architecture on a GB202 chip, fabricated by TSMC on a 5 nm process. The LX PRO uses an architecture labeled TrueGPU on a 7G105 chip, also from TSMC but on a 6 nm node. The process difference is small, but the transistor count is not comparable: the RTX PRO 5000 packs 92,200 million transistors on a 750 mm² die, giving a density of 122.9 million per square millimeter. The LX PRO's transistor count and die size are not recorded in the database.

The NVIDIA card integrates 14,080 shading units, 440 texture mapping units, and 160 raster output pipelines. It also carries 110 RT cores and 440 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT cores or tensor cores listed. That absence is significant: the database records no ray tracing or tensor hardware for the LX PRO, while the RTX PRO 5000 has dedicated units for both.

Memory architecture differs substantially. The RTX PRO 5000 uses 48 GB of GDDR7 with a 384-bit interface. The LX PRO uses 24 GB of GDDR6 with a 192-bit interface. Clock speeds also differ: the NVIDIA card runs its memory at 1750 MHz with 28 Gbps effective data rate, while the LX PRO runs at 2250 MHz with 18 Gbps effective. The wider bus on the NVIDIA card more than compensates for the lower memory clock.

Interface standards also separate the two. The RTX PRO 5000 uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. Display outputs differ as well: the NVIDIA card has 4x DisplayPort 2.1b, while the LX PRO has 4x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the NVIDIA card supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3.

Power requirements are notably different. The RTX PRO 5000 has a TDP of 300 W with a suggested PSU of 700 W. The LX PRO draws 225 W with a suggested PSU of 550 W. Both are dual-slot cards with a single 16-pin power connector. Physical dimensions are close: the NVIDIA card is 267 mm long, 111 mm tall, and 40 mm wide; the LX PRO is 248 mm long, 118 mm tall, and 48 mm wide.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two cards. The RTX PRO 5000 has three recorded benchmark scores, while the LX PRO has zero. However, the RTX PRO 5000's nearest rivals provide context for its standing. Its average benchmark score is 182,109, which sits 0.9% below the NVIDIA A100 SXM4 80 GB (183,725), 1.4% below the NVIDIA RTX 5000 Ada Generation (184,664), 2.3% above the NVIDIA GeForce RTX 4090 D (178,050), and 2.7% below the NVIDIA A100 SXM4 40 GB (187,147).

The 3DMark Steel Nomad DX12 score of 9,579.5 places the RTX PRO 5000 in the top tier of workstation GPUs. Its Geekbench OpenCL score of 254,116 and Vulkan score of 282,631 both indicate strong compute throughput. The Vulkan score is 11.2% higher than the OpenCL score, suggesting the Blackwell architecture handles Vulkan's compute model particularly well.

The LX PRO's average benchmark score is recorded as 0, with no percentile data relative to rivals. Its 50th percentile among all GPUs is a positional marker, but without actual benchmark numbers, the database cannot quantify its performance against the RTX PRO 5000. What can be compared is architectural throughput: the RTX PRO 5000's FP32 output of 66.94 TFLOPS is 2.7 times the LX PRO's 24.58 TFLOPS. The pixel rate of 380.3 GPixel/s on the NVIDIA card is 1.98 times the LX PRO's 192.0 GPixel/s. The texture rate of 1,045.9 GTexel/s is 2.7 times the LX PRO's 384.0 GTexel/s.

Memory bandwidth tells a similar story. The RTX PRO 5000's 1.34 TB/s is 3.1 times the LX PRO's 432.0 GB/s. These ratios are consistent across compute, pixel, texture, and memory metrics, indicating the NVIDIA card is roughly three times faster in raw throughput terms across the board.

The Verdict

The recorded data gives a one-sided picture. The NVIDIA RTX PRO 5000 Blackwell outperforms the Lisuan Tech LX PRO in every measurable category where both have data. Its FP32 throughput is 2.7 times higher, its pixel rate is nearly double, its texture rate is 2.7 times higher, and its memory bandwidth is 3.1 times higher. It carries more than twice the VRAM, supports newer display and bus standards, and includes dedicated RT and tensor cores that the LX PRO lacks.

The LX PRO's strengths are relative, not absolute. Its FP16 output at 2:1 ratio means it doubles throughput over FP32, a trait that could benefit specific mixed-precision workloads. Its lower TDP of 225 W and suggested PSU of 550 W indicate a more modest power footprint than the RTX PRO 5000's 300 W and 700 W figures. Its physical dimensions are slightly shorter at 248 mm versus 267 mm.

For users prioritizing maximum compute throughput, memory capacity, and feature completeness, the RTX PRO 5000 is the clear choice based on all recorded metrics. Its 98th percentile standing among all GPUs and its competitive position against the A100 series reinforce that conclusion. The LX PRO, positioned at the 50th percentile with no recorded benchmark scores, cannot be quantitatively validated against the NVIDIA card in the database. Its architectural characteristics suggest a mid-range workstation card, but the data does not support a performance claim beyond that.
