Where Each One Wins

The RTX PRO 4000 Blackwell SFF wins in compute unit count and architectural features. Its 8960 shading units and 280 TMUs exceed the LX PRO's 6144 and 192 respectively. It includes 70 RT cores and 280 tensor cores, which the LX PRO does not list. Its Blackwell 2.0 architecture on a 5 nm process with 45,600 million transistors represents a denser manufacturing approach. The RTX PRO 4000 also supports Vulkan 1.4 versus the LX PRO's Vulkan 1.3, and uses GDDR7 memory. Its 70 W TDP with no power connectors and 250 W suggested PSU indicates a low-power design suited to constrained systems. The smaller dimensions, 167 mm length versus 248 mm, make it more adaptable to compact chassis.

The LX PRO wins in raw throughput metrics where the database provides numbers. Its FP32 compute of 24.58 TFLOPS exceeds the RTX PRO 4000's 24.05 TFLOPS. Its FP16 throughput of 49.15 TFLOPS more than doubles the RTX PRO 4000's 24.05 TFLOPS. Its pixel rate of 192.0 GPixel/s is 49% higher than the RTX PRO 4000's 128.8 GPixel/s. Its texture rate of 384.0 GTexel/s is 2.2% higher than 375.8 GTexel/s. The LX PRO uses PCIe 4.0 x16, a wider interface than the RTX PRO 4000's PCIe 5.0 x8, though the newer PCIe generation on the RTX PRO 4000 may offset the bandwidth difference. The LX PRO's larger physical footprint and 225 W TDP suggest it is designed as a full-size card with more substantial power delivery.

The RTX PRO 4000 has a recorded benchmark score of 2910, indicating verified performance in the database. The LX PRO has no benchmark entries, so its theoretical throughput advantages remain unmeasured. The RTX PRO 4000's percentile of 19 places it among the lower-performing GPUs in the database, while the LX PRO's percentile of 50 carries no supporting benchmark data.

The Verdict

The data presents an incomplete comparison due to the absence of benchmark results for the LX PRO. The RTX PRO 4000 Blackwell SFF has one recorded score, 2910 in 3DMark Steel Nomad, which places it within 0.6% of several GeForce and Quadro cards. The LX PRO has no recorded scores, no nearest rivals, and an average benchmark score of zero.

For users who require verified performance data, the RTX PRO 4000 is the only card with measurable results. Its low power draw of 70 W, compact dimensions, and no power connector requirement make it suitable for systems with limited power budgets and space. Its RT cores and tensor cores provide hardware acceleration for ray tracing and AI workloads, and its Vulkan 1.4 support offers a newer graphics API.

For users who prioritize raw theoretical throughput, the LX PRO presents higher FP32 and FP16 compute figures, higher pixel and texture rates, and a wider PCIe interface. Its 225 W TDP and 550 W suggested PSU indicate a more power-hungry design. The lack of any benchmark entries means these advantages are unverified in the database.

The release dates differ by approximately seven months, with the RTX PRO 4000 appearing earlier in the database. The production status for both is listed as Active.

The choice depends on whether the user values measured benchmark performance and low power consumption versus higher theoretical rasterization throughput and a larger physical design. The RTX PRO 4000 offers proven performance in one test, while the LX PRO offers higher spec sheet numbers without recorded validation.
