NVIDIA RTX PRO 5000 72 GB Blackwell vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The NVIDIA RTX PRO 5000 72 GB Blackwell and the Lisuan Tech LX PRO occupy completely different segments of the GPU market, and the data reflects that split clearly. The RTX PRO 5000 is a professional workstation card built around the GB202 chip on the Blackwell 2.0 architecture, while the LX PRO is a TrueGPU architecture card from Lisuan Tech targeting a different workload profile entirely.

For compute-heavy professional tasks, the RTX PRO 5000 dominates. Its FP32 throughput of 66.94 TFLOPS more than doubles the LX PRO's 24.58 TFLOPS, giving it a decisive edge in single-precision compute workloads like scientific simulation, rendering, and AI inference. The RTX PRO 5000 also delivers far higher texture and pixel rates, with 1,045.9 GTexel/s against the LX PRO's 384.0 GTexel/s, and 380.3 GPixel/s versus 192.0 GPixel/s. This makes it the clear choice for rasterization-heavy tasks, 3D modeling, and any application that pushes raw fill rates.

The LX PRO, however, wins on efficiency and physical footprint. Its 225 W TDP is 75 W lower than the RTX PRO 5000's 300 W, and its suggested PSU requirement of 550 W versus 700 W means it slots into more modest systems. The card is also shorter at 248 mm compared to 267 mm, though it is slightly taller and wider. For environments where power delivery and chassis space are constrained, the LX PRO holds an advantage.

Memory capacity is another stark differentiator. The RTX PRO 5000 carries 72 GB of GDDR7 on a 384-bit bus, delivering 1.34 TB/s of bandwidth. The LX PRO offers 24 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s. For large dataset workloads like training massive models or handling multi-gigabyte textures, the RTX PRO 5000's memory subsystem is in a different class. The LX PRO's 24 GB is sufficient for many mid-range tasks but will hit ceilings on the largest datasets.

Neither card wins in API support outright, as both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX PRO 5000 supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3, a modest but real difference for Vulkan-based applications. The RTX PRO 5000 also uses newer DisplayPort 2.1b outputs versus the LX PRO's DisplayPort 1.4a, enabling higher refresh rates and resolutions on compatible monitors.

Architecture Differences

The two cards come from fundamentally different design philosophies. The RTX PRO 5000 uses the GB202 chip, fabricated on a 5 nm process at TSMC, with 92,200 million transistors packed into a 750 mm² die. That yields a transistor density of 122.9M per mm². The LX PRO uses the 7G105 chip on a 6 nm process, also from TSMC, but its transistor count and die size are not recorded in the database.

The RTX PRO 5000's Blackwell 2.0 architecture includes dedicated RT cores and tensor cores, with 110 RT cores and 440 tensor cores. The LX PRO's TrueGPU architecture has no recorded RT cores or tensor cores, meaning hardware-accelerated ray tracing and tensor operations rely on other mechanisms or are absent entirely. This is a critical architectural difference for any workload that uses these dedicated units.

Shader configuration differs substantially. The RTX PRO 5000 has 14,080 shading units, 440 TMUs, and 160 ROPs. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. These numbers explain the performance gap in raw throughput, as the RTX PRO 5000 has more than twice the shading units and more than double the TMUs and ROPs.

The FP16 capabilities reveal a different design choice. The RTX PRO 5000 runs FP16 at 66.94 TFLOPS with a 1:1 ratio to FP32, meaning it does not dedicate extra hardware to half-precision. The LX PRO runs FP16 at 49.15 TFLOPS with a 2:1 ratio, effectively doubling its FP16 throughput relative to FP32. This suggests the LX PRO is tuned for workloads that benefit from half-precision arithmetic, although its absolute FP16 output still trails the RTX PRO 5000.

Memory architecture also differs fundamentally. The RTX PRO 5000 uses GDDR7 across a 384-bit bus, while the LX PRO uses GDDR6 across a 192-bit bus. The RTX PRO 5000's memory clock is 1750 MHz with 28 Gbps effective, while the LX PRO runs at 2250 MHz with 18 Gbps effective. Despite the lower memory clock, the RTX PRO 5000's wider bus and newer memory type produce far higher bandwidth.

The bus interface differs as well: PCIe 5.0 x16 on the RTX PRO 5000 versus PCIe 4.0 x16 on the LX PRO. This affects data transfer between the GPU and host system, with the newer standard offering higher theoretical bandwidth for workloads that stream data frequently. The power connectors are identical at 1x 16-pin for both cards.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the RTX PRO 5000 and the LX PRO. The RTX PRO 5000 has eight recorded benchmark scores across 3DMark and Passmark tests, while the LX PRO has no benchmark entries at all. This absence of comparable data means the performance comparison must rely on the recorded specifications rather than measured test results.

The RTX PRO 5000's recorded benchmarks show an average score of 6407 across all tests, placing it at the 37th percentile of all GPUs in the database. Its 3DMark Steel Nomad DX12 score is 9579.5, and its Passmark G3D score is 24310. The Passmark GPU compute score is 15667. These numbers establish a baseline for the card's performance in the database, though they cannot be directly compared to the LX PRO, which has no scores.

The RTX PRO 5000's nearest rivals in the database are older and lower-performing cards. It sits 0.3% above the NVIDIA GeForce GTX 460 SE and GTX 580M, both with average scores of 6389. It sits 1.1% below the AMD Radeon Vega 10 Mobile and NVIDIA Quadro M5000M, both with average scores of 6476 and 6481 respectively. These deltas are tiny, indicating the RTX PRO 5000's benchmark average is tightly clustered with these cards, despite the massive architectural differences between them.

This clustering is notable because the RTX PRO 5000's specification sheet suggests far higher performance than these rivals. The discrepancy between its raw specs and its percentile ranking indicates the database's benchmark suite may not fully exercise the card's capabilities, or the recorded scores reflect specific test conditions. The LX PRO's complete lack of benchmark data means no similar analysis is possible for it.

The FP32 and FP16 numbers provide the clearest cross-card comparison available. The RTX PRO 5000's 66.94 TFLOPS FP32 is 172% higher than the LX PRO's 24.58 TFLOPS, a gap of roughly 2.7x. In FP16, the RTX PRO 5000 still leads with 66.94 TFLOPS versus 49.15 TFLOPS, a 36% advantage. Texture rate shows a 2.7x lead for the RTX PRO 5000, and pixel rate shows a 2.0x lead. These ratios give a practical sense of the performance differential across different workload types.

The Verdict

The data points to a clear separation of use cases. The NVIDIA RTX PRO 5000 72 GB Blackwell is the higher-performance card by every measurable specification in the database. Its 66.94 TFLOPS FP32, 1.34 TB/s bandwidth, 72 GB memory, and 14,080 shading units place it firmly in the professional workstation tier. The dedicated 110 RT cores and 440 tensor cores add hardware support for ray tracing and tensor operations that the LX PRO lacks entirely. For any workload that stresses compute throughput, memory capacity, or specialized hardware acceleration, the RTX PRO 5000 is the only choice between these two.

The Lisuan Tech LX PRO has its own strengths, though they are narrower. Its 225 W TDP and 550 W suggested PSU make it easier to integrate into systems with tighter power budgets. Its shorter 248 mm length fits in smaller chassis. Its FP16 ratio of 2:1 suggests some optimization for half-precision work, though its absolute FP16 output of 49.15 TFLOPS still trails the RTX PRO 5000's 66.94 TFLOPS. The 24 GB memory capacity and 432.0 GB/s bandwidth are adequate for mid-range tasks but will bottleneck on large datasets.

The RTX PRO 5000's benchmark data shows an average score of 6407 and a 37th percentile ranking, with nearest rivals that are much older cards. This indicates the recorded scores may not fully represent its capability, given its specification advantage over those rivals. The LX PRO has no benchmark data at all, so its real-world performance cannot be validated from the database.

The verdict from the recorded data is straightforward: the RTX PRO 5000 is the superior card for compute-intensive professional workloads, and the LX PRO is the more power-efficient, compact alternative for lighter tasks. The 75 W lower TDP and smaller footprint of the LX PRO are real advantages, but they come with substantial sacrifices in every performance metric. The RTX PRO 5000's 72 GB memory and 1.34 TB/s bandwidth alone justify its position for large-scale data work, and its compute advantages reinforce that conclusion. The LX PRO is a capable option for constrained environments, but the data gives no scenario where it outperforms the RTX PRO 5000 on raw capability.
