NVIDIA RTX PRO 4000 Blackwell SFF vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the NVIDIA RTX PRO 4000 Blackwell SFF and the Lisuan Tech LX MAX. The NVIDIA card has a single benchmark entry, a 3DMark Steel Nomad DX12 score of 2910, placing it at the 19th percentile among all GPUs in the database. The Lisuan Tech LX MAX has no benchmark entry and an average score of 0, which is not a meaningful performance indicator.

For context, the NVIDIA card's score of 2910 sits within a tight cluster of rival GPUs. The nearest rival, the NVIDIA GeForce RTX 4060 Ti 16 GB, scores 2907, which is 0.1% behind the RTX PRO 4000 Blackwell SFF. The NVIDIA GeForce RTX 4060 Ti 8 GB scores 2913, 0.1% ahead. The NVIDIA Quadro P600 scores 2923, 0.4% ahead, and the NVIDIA GeForce RTX 4010 scores 2893, 0.6% behind. These deltas are small enough to indicate that the RTX PRO 4000 Blackwell SFF delivers performance virtually identical to that class of GPU in this specific test.

Because the Lisuan Tech LX MAX has no recorded benchmark scores, the database cannot establish a direct comparison. The absence of data for the LX MAX means any head-to-head analysis must rely on architectural and specification differences rather than actual measured results. The NVIDIA card's 19th percentile ranking suggests it outperforms roughly 81% of all GPUs in the database, but that figure does not account for the LX MAX, which remains unranked due to missing benchmark data.

Where Each One Wins

Without head-to-head benchmarks, the wins must be inferred from specifications. The NVIDIA RTX PRO 4000 Blackwell SFF delivers higher memory capacity at 24 GB of GDDR7, which is double the 12 GB of GDDR6 in the Lisuan Tech LX MAX. The NVIDIA card also supports PCIe 5.0 x8, while the LX MAX uses PCIe 4.0 x16, giving the NVIDIA card a newer bus interface generation. The NVIDIA card features 70 RT cores and 280 tensor cores, whereas the LX MAX lists no RT cores or tensor cores in its specifications, indicating a clear advantage for ray tracing and AI-accelerated workloads on the NVIDIA side.

The Lisuan Tech LX MAX counters with a higher FP32 throughput of 24.58 TFLOPS compared to 24.05 TFLOPS on the NVIDIA card, a difference of approximately 2.2%. The LX MAX also delivers FP16 performance of 49.15 TFLOPS (2:1 ratio), while the NVIDIA card achieves 24.05 TFLOPS (1:1 ratio), meaning the LX MAX has a substantial lead in half-precision compute. The LX MAX shows a higher pixel rate of 192.0 GPixel/s versus 128.8 GPixel/s, a 49% advantage, and a higher texture rate of 384.0 GTexel/s versus 375.8 GTexel/s, a 2.2% edge. These figures suggest the LX MAX is built for raw compute throughput and fill-rate-heavy tasks.

The NVIDIA card wins on power efficiency with a TDP of 70 W versus 225 W for the LX MAX, and it requires a suggested PSU of 250 W compared to 550 W for the LX MAX. The NVIDIA card also uses no power connectors, while the LX MAX requires a 16-pin connector. The NVIDIA card is physically smaller at 167 mm in length, 69 mm in height, and 40 mm in width, compared to the LX MAX at 248 mm, 118 mm, and 48 mm, making the NVIDIA card more suitable for space-constrained systems.

Architecture Differences

The NVIDIA RTX PRO 4000 Blackwell SFF is built on the GB203 chip using the Blackwell 2.0 architecture, manufactured on 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 MAX uses the 7G106 chip with the TrueGPU architecture, manufactured on a 6 nm process at TSMC, with transistor count and die size listed as unknown. The NVIDIA card belongs to the Blackwell PRO W (x000) generation, while the LX MAX belongs to the 7G100 generation.

Memory architecture differs significantly. The NVIDIA card uses 24 GB of GDDR7 with a 192-bit bus and 432.0 GB/s bandwidth. The LX MAX uses 12 GB of GDDR6 with the same 192-bit bus and identical 432.0 GB/s bandwidth. Both cards achieve the same memory bandwidth despite the capacity difference, due to the NVIDIA card's higher memory clock of 1125 MHz (18 Gbps effective) versus 2250 MHz (18 Gbps effective) on the LX MAX, though the effective data rates match.

Compute unit counts diverge: the NVIDIA card has 8960 shading units, 280 TMUs, and 96 ROPs, while the LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs. The NVIDIA card's shading unit count is 45.8% higher, and its TMU count is 45.8% higher, but both share the same ROP count. The NVIDIA card includes 70 RT cores and 280 tensor cores; the LX MAX lists neither, indicating the absence of dedicated ray tracing and tensor processing hardware.

API support shows partial overlap. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The NVIDIA card supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Display outputs also differ: the NVIDIA card provides 4x mini-DisplayPort 2.1b, while the LX MAX provides 4x DisplayPort 1.4a. The NVIDIA card's memory clock is listed as 1125 MHz with 18 Gbps effective, which is a lower physical clock but the same effective data rate as the LX MAX's 2250 MHz with 18 Gbps effective.

Power delivery and physical specifications reflect different design goals. The NVIDIA card has a 70 W TDP with no power connectors and a suggested PSU of 250 W, while the LX MAX has a 225 W TDP with a single 16-pin connector and a suggested PSU of 550 W. The NVIDIA card is a dual-slot design measuring 167 mm by 69 mm by 40 mm, while the LX MAX is also dual-slot but measures 248 mm by 118 mm by 48 mm. The LX MAX's larger footprint accommodates its higher power draw and cooling requirements.

The Verdict

The data indicates that the NVIDIA RTX PRO 4000 Blackwell SFF is the better choice for workloads requiring high memory capacity, ray tracing, tensor acceleration, and power efficiency. Its 24 GB of GDDR7 doubles the LX MAX's 12 GB, and its 70 RT cores and 280 tensor cores provide hardware acceleration that the LX MAX lacks entirely. The NVIDIA card's 70 W TDP and 250 W suggested PSU make it suitable for low-power and compact systems, while its PCIe 5.0 x8 interface offers a newer bus standard. The only recorded benchmark, a 3DMark Steel Nomad DX12 score of 2910, places it in the 19th percentile, with performance nearly identical to the GeForce RTX 4060 Ti series, which shows deltas of 0.1% or less.

The Lisuan Tech LX MAX is the better choice for raw compute throughput and fill-rate performance. Its FP32 output of 24.58 TFLOPS exceeds the NVIDIA card's 24.05 TFLOPS, and its FP16 output of 49.15 TFLOPS is more than double the NVIDIA card's 24.05 TFLOPS. The LX MAX also delivers a pixel rate of 192.0 GPixel/s, which is 49% higher, and a texture rate of 384.0 GTexel/s, which is 2.2% higher. These specifications suggest an advantage for compute-heavy tasks such as scientific simulation or half-precision machine learning workloads, though the absence of RT cores and tensor cores limits its applicability in ray-traced rendering and AI inference. The LX MAX's higher TDP of 225 W and 550 W suggested PSU indicate it is a power-hungry part intended for larger systems.

The Verdict is straightforward: the NVIDIA RTX PRO 4000 Blackwell SFF is the more versatile and efficient option for professional workstation use, particularly for rendering, AI, and compact builds. The Lisuan Tech LX MAX is a compute-oriented card with a higher theoretical throughput, but its lack of benchmark data and missing RT and tensor core support makes it a narrower fit. The database's performance data currently only supports the NVIDIA card's measured score, so any LX MAX advantage is purely speculative based on specifications.
