Head-to-Head Benchmarks

The database contains nine benchmark results for the NVIDIA RTX PRO 4000 Blackwell, covering DirectX, Vulkan, and compute workloads. The LX PRO has no recorded benchmarks, so the comparison relies on the RTX PRO 4000 Blackwell’s scores and its nearest rivals to establish a performance context. The RTX PRO 4000 Blackwell’s average benchmark score of 27135 sits within 1.7% of the NVIDIA RTX A4000, which averages 26683. This places the RTX PRO 4000 Blackwell slightly ahead of its direct workstation predecessor by a margin of 1.7%. Against the AMD Radeon RX 6700 XT, the RTX PRO 4000 Blackwell trails by 1.1%, with the AMD card averaging 27425. The NVIDIA GeForce RTX 4070 Mobile also beats it by 1.1%, averaging 27435, and the RTX 3090 leads by 1.6% with an average of 27565. These deltas are narrow, indicating that the RTX PRO 4000 Blackwell performs in the same class as these established GPUs despite being a workstation-focused product.

Looking at individual tests, the RTX PRO 4000 Blackwell scores 4648 in 3DMark Steel Nomad DX12, 194168 in Geekbench Vulkan, and 28427 in Passmark G3D. The Passmark suite also shows 14805 for GPU compute, 1265 for G2D, and 354 for DirectX 9. DirectX 10 and DirectX 11 scores are 173 and 276 respectively, while DirectX 12 comes in at 97. These numbers reveal a strong compute and modern API performance profile, with the Vulkan score notably high compared to the DirectX 12 result. The data indicates the RTX PRO 4000 Blackwell excels in asynchronous and low-level API workloads, likely due to its architecture design. Since the LX PRO has no benchmark entries, the database cannot provide direct head-to-head wins for either card, but the RTX PRO 4000 Blackwell’s recorded performance against rivals gives a clear baseline.

The nearest rival data suggests the RTX PRO 4000 Blackwell is competitive with gaming cards like the RTX 3090, which historically offers much higher raw compute. The 1.6% deficit to the RTX 3090 in average score is small, and the RTX PRO 4000 Blackwell’s workstation features likely compensate in professional workloads. No wins are recorded for either card in the head-to-head section, as the LX PRO lacks any test results. The RTX PRO 4000 Blackwell’s percentile rank of 72 versus the LX PRO’s 50 percentile further underscores the gap, but the absence of LX PRO benchmarks means all performance statements must reference only the RTX PRO 4000 Blackwell’s data.

Architecture Differences

The two cards use fundamentally different chip designs. The NVIDIA RTX PRO 4000 Blackwell is built on the GB203 chip using a 5 nm process at TSMC, with 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per mm². The Lisuan Tech LX PRO uses the 7G105 chip on a 6 nm process, also from TSMC, but the database lists its transistor count and die size as unknown. This process node difference means the RTX PRO 4000 Blackwell packs more transistors into a smaller area, which typically allows for higher compute density and efficiency. The LX PRO’s 6 nm node is one generation behind, but without transistor data, the full comparison remains incomplete.

Architecture names also differ: the RTX PRO 4000 Blackwell uses Blackwell 2.0, while the LX PRO employs TrueGPU. The generation labels are Blackwell PRO W (x000) for NVIDIA and 7G100 for Lisuan. Clock speeds show a stark contrast. The RTX PRO 4000 Blackwell has a base clock of 1230 MHz and a boost clock of 2055 MHz, while the LX PRO lists no base or boost clocks. Memory clocks differ too: the RTX PRO 4000 Blackwell runs at 1750 MHz with 28 Gbps effective, and the LX PRO runs at 2250 MHz with 18 Gbps effective. Despite the LX PRO’s higher memory clock frequency, its effective data rate is lower due to the GDDR6 memory type versus the RTX PRO 4000 Blackwell’s GDDR7.

Memory architecture is similar in capacity and bus width, with both cards featuring 24 GB and a 192-bit bus. However, bandwidth diverges significantly: the RTX PRO 4000 Blackwell delivers 672.0 GB/s, while the LX PRO provides 432.0 GB/s. This 240 GB/s difference stems from the memory type, as GDDR7 offers higher per-pin data rates than GDDR6. Compute resources also differ. The RTX PRO 4000 Blackwell has 8960 shading units, 280 texture mapping units, and 96 raster output processors. It also includes 70 ray tracing cores and 280 tensor cores. The LX PRO has 6144 shading units, 192 texture mapping units, and 96 raster output processors, but it has no listed ray tracing or tensor cores. This absence suggests the LX PRO lacks dedicated hardware for ray tracing and AI acceleration, limiting its capabilities in those workloads.

Pixel and texture rates reflect these resource counts. The RTX PRO 4000 Blackwell achieves 197.3 GPixel/s and 575.4 GTexel/s, while the LX PRO reaches 192.0 GPixel/s and 384.0 GTexel/s. The texture rate gap is notable, with the RTX PRO 4000 Blackwell delivering roughly 50% more texture throughput. Floating-point performance also favors NVIDIA: the RTX PRO 4000 Blackwell offers 36.83 TFLOPS for both FP32 and FP16 with a 1:1 ratio, while the LX PRO provides 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 with a 2:1 ratio. The LX PRO’s higher FP16 throughput comes at the cost of FP32 performance, which is often more relevant for general compute workloads.

Power and physical design differ substantially. The RTX PRO 4000 Blackwell has a 140 W TDP, is single-slot, and requires a 300 W suggested PSU. The LX PRO has a 225 W TDP, is dual-slot, and needs a 550 W suggested PSU. The LX PRO also uses a PCIe 4.0 x16 interface versus the RTX PRO 4000 Blackwell’s PCIe 5.0 x16, which halves the available bandwidth for data transfers. Display outputs differ as well: the RTX PRO 4000 Blackwell offers 4x DisplayPort 2.1b, while the LX PRO has 4x DisplayPort 1.4a. Both cards support DirectX 12 Ultimate and OpenGL 4.6, but the RTX PRO 4000 Blackwell supports Vulkan 1.4 versus the LX PRO’s Vulkan 1.3.

The Verdict

The data clearly indicates that the NVIDIA RTX PRO 4000 Blackwell outperforms the Lisuan Tech LX PRO across most measurable specifications, but the LX PRO has no benchmark scores to provide a direct performance comparison. The RTX PRO 4000 Blackwell’s average benchmark score of 27135 and 72nd percentile ranking show it is a capable mid-range workstation GPU, while the LX PRO’s 50th percentile and zero average score reflect an unproven performance profile. For users requiring ray tracing, tensor core acceleration, or high memory bandwidth, the RTX PRO 4000 Blackwell is the only option with those features. The LX PRO’s lack of ray tracing and tensor cores means it cannot handle professional workloads that rely on those units, such as real-time ray-traced rendering or AI inference.

The RTX PRO 4000 Blackwell also wins on efficiency, with a 140 W TDP versus the LX PRO’s 225 W, and it fits in a single slot, making it easier to integrate into dense workstation builds. The LX PRO’s dual-slot design and higher power draw require more physical space and a stronger PSU. However, the LX PRO’s FP16 throughput of 49.15 TFLOPS exceeds the RTX PRO 4000 Blackwell’s 36.83 TFLOPS, which could benefit certain compute workloads that use FP16 precision extensively. But the database does not provide benchmark results to confirm this advantage in practice.

For buyers strictly evaluating recorded data, the RTX PRO 4000 Blackwell is the safer choice due to its proven benchmark scores and modern feature set. The LX PRO’s only advantages are its higher FP16 rate and lower memory clock frequency, which does not translate to higher bandwidth. The RTX PRO 4000 Blackwell’s 672.0 GB/s bandwidth is 55% higher than the LX PRO’s 432.0 GB/s, a critical factor for memory-intensive tasks. Given the absence of LX PRO benchmarks, the verdict favors the NVIDIA card for any workload that benefits from the recorded performance metrics.
