NVIDIA RTX PRO 4000 Blackwell vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The NVIDIA RTX PRO 4000 Blackwell and the Lisuan Tech LX MAX occupy different positions in the performance spectrum, and the recorded data shows a clear split in their intended workloads. The RTX PRO 4000 Blackwell delivers its results through a complete set of benchmark scores, while the LX MAX has no recorded benchmark entries in the database, which limits direct comparison to architectural and specification analysis rather than measured performance.

The RTX PRO 4000 Blackwell wins on raw compute throughput in every measurable category. Its FP32 output reaches 36.83 TFLOPS, which is 49.8% higher than the LX MAX's 24.58 TFLOPS. The shading unit count of 8960 versus 6144 gives the NVIDIA part a 45.6% advantage in parallel processing capacity. Texture fill rate follows the same pattern: 575.4 GTexel/s against 384.0 GTexel/s, a 49.8% gap. These numbers indicate that the RTX PRO 4000 Blackwell is the stronger choice for compute-heavy tasks such as rendering, simulation, and GPU-accelerated workloads that rely on FP32 throughput.

The LX MAX wins in two specific areas based on the available data. Its pixel rate reaches 192.0 GPixel/s, slightly ahead of the RTX PRO 4000 Blackwell's 197.3 GPixel/s? No, the NVIDIA part actually holds a 2.8% lead there. The LX MAX does win on FP16 throughput with 49.15 TFLOPS versus the RTX PRO 4000 Blackwell's 36.83 TFLOPS, a 33.5% advantage. This stems from the LX MAX's 2:1 FP16 ratio, meaning it processes half-precision data at twice the rate of single-precision. The RTX PRO 4000 Blackwell uses a 1:1 ratio, so its FP16 equals its FP32. For workloads that leverage FP16, such as certain AI inference tasks or mixed-precision computing, the LX MAX offers higher theoretical throughput.

The memory configuration also favors different use cases. The RTX PRO 4000 Blackwell carries 24 GB of GDDR7 with 672.0 GB/s bandwidth, while the LX MAX has 12 GB of GDDR6 at 432.0 GB/s. The NVIDIA part provides double the capacity and 55.6% more bandwidth, which matters for large datasets and high-resolution textures. The LX MAX's smaller memory pool limits its ability to handle scenes or models that exceed 12 GB, but its FP16 advantage could appeal to specific compute scenarios.

Architecture Differences

The two cards come from different architectural lineages. The RTX PRO 4000 Blackwell uses the GB203 chip built on TSMC's 5 nm process, part of the Blackwell 2.0 architecture and the Blackwell PRO W (x000) generation. It packs 45,600 million transistors into a 378 mm² die, yielding a transistor density of 120.6M per mm². The LX MAX uses the 7G106 chip on TSMC's 6 nm process, belonging to the TrueGPU architecture and the 7G100 generation. Its transistor count and die size remain unknown in the database.

The RTX PRO 4000 Blackwell includes dedicated ray tracing cores (70) and tensor cores (280), features that are absent from the LX MAX's specification sheet, which lists no RT or tensor core counts. This difference affects how each card handles ray-traced rendering and tensor-based operations. The NVIDIA part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX MAX matches DirectX 12 Ultimate (12_2) and OpenGL 4.6 but only reaches Vulkan 1.3.

Memory technology differs significantly. The RTX PRO 4000 Blackwell uses GDDR7 running at 1750 MHz with 28 Gbps effective speed, while the LX MAX uses GDDR6 at 2250 MHz with 18 Gbps effective speed. Both use a 192-bit bus, but the newer GDDR7 standard gives the NVIDIA card a substantial bandwidth advantage despite its lower memory clock. The RTX PRO 4000 Blackwell also connects via PCIe 5.0 x16, whereas the LX MAX uses PCIe 4.0 x16.

Physical design separates the two as well. The RTX PRO 4000 Blackwell is a single-slot card measuring 241 mm in length, 111 mm in height, and 20 mm in width. The LX MAX takes a dual-slot design at 248 mm long, 118 mm tall, and 48 mm wide, making it considerably thicker. Both use a single 16-pin power connector, but the suggested PSU rating differs: 300 W for the NVIDIA part and 550 W for the LX MAX. The RTX PRO 4000 Blackwell also has a lower TDP at 140 W versus 225 W, which aligns with its smaller physical footprint.

Display outputs vary by generation. The RTX PRO 4000 Blackwell provides four DisplayPort 2.1b connectors, while the LX MAX offers four DisplayPort 1.4a connectors. The newer DisplayPort standard on the NVIDIA card supports higher bandwidth for high-resolution, high-refresh-rate displays.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two cards. The RTX PRO 4000 Blackwell has its own benchmark suite, while the LX MAX has zero recorded scores. This absence of direct comparison data means the analysis relies on specification-level differences and the NVIDIA card's standalone performance metrics.

The RTX PRO 4000 Blackwell scores 4648 in 3DMark Steel Nomad (DX12), 194168 in Geekbench Vulkan, and 28427 in Passmark G3D. Its Passmark GPU compute score is 14805. The card achieves an average benchmark score of 27135 and sits at the 72nd percentile among all GPUs. Its nearest rivals in the database include the AMD Radeon RX 6700 XT (27425 average score, 1.1% ahead), NVIDIA GeForce RTX 4070 Mobile (27435, 1.1% ahead), NVIDIA GeForce RTX 3090 (27565, 1.6% ahead), and NVIDIA RTX A4000 (26683, 1.7% behind). These deltas show the RTX PRO 4000 Blackwell performing within a narrow band around its closest competitors, slightly behind the top three but ahead of the RTX A4000.

The LX MAX has no benchmark scores, no average score, and no rival comparisons. Its 50th percentile placement among all GPUs reflects the absence of measured data rather than actual performance. Without benchmark results, any performance claims for the LX MAX must come from its specification sheet alone.

The Verdict

The data supports the RTX PRO 4000 Blackwell as the stronger card for most professional workloads. Its 49.8% higher FP32 throughput, double the memory capacity, and 55.6% greater bandwidth make it the clear choice for rendering, simulation, and large-scale data processing. The 70 RT cores and 280 tensor cores add capabilities that the LX MAX does not specify. The NVIDIA card also runs cooler at 140 W TDP, fits in a single slot, and uses the newer PCIe 5.0 interface and DisplayPort 2.1b outputs.

The LX MAX offers one meaningful advantage: FP16 throughput. Its 49.15 TFLOPS at 2:1 ratio exceeds the NVIDIA card by 33.5%, which could benefit workloads that operate primarily in half precision. However, the absence of benchmark scores prevents validation of this theoretical advantage in real applications. The LX MAX also uses more power (225 W TDP) and requires a larger PSU (550 W), yet delivers fewer shading units and lower texture rate.

For builders who need a proven, benchmarked workstation card with substantial memory and broad feature support, the RTX PRO 4000 Blackwell is the data-backed choice. The LX MAX remains an unverified alternative with a niche FP16 strength and no recorded performance evidence. The RTX PRO 4000 Blackwell's 72nd percentile placement and its competitive standing against the RTX 3090 and RX 6700 XT confirm its measured capability. The LX MAX's 50th percentile is a placeholder, not a performance verdict.
