NVIDIA RTX PRO 4500 Blackwell Workstation vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database shows no direct head-to-head benchmark results between the NVIDIA RTX PRO 4500 Blackwell Workstation and the Lisuan Tech LX PRO. Both GPUs sit at the 50th percentile among all GPUs in the database, with an average benchmark score of 0. This means neither card has recorded performance data that would allow for a direct comparison of wins or losses.

The FP32 compute figures, however, provide a clear performance split. The RTX PRO 4500 delivers 50.53 TFLOPS of FP32 throughput, which is more than double the LX PRO's 24.58 TFLOPS. In FP16 workloads, the situation changes: the RTX PRO 4500 maintains a 1:1 ratio at 50.53 TFLOPS, while the LX PRO uses a 2:1 ratio to reach 49.15 TFLOPS. The LX PRO nearly matches the RTX PRO 4500 in FP16 despite its lower raw FP32 capability.

Pixel throughput favors the RTX PRO 4500 at 269.6 GPixel/s versus 192.0 GPixel/s for the LX PRO. Texture rate tells a similar story: 789.5 GTexel/s for the NVIDIA card, 384.0 GTexel/s for the Lisuan Tech card. The RTX PRO 4500 holds a 2.06x advantage in texture fill rate, which directly impacts geometric and shader-heavy workloads.

Memory bandwidth shows the largest single-specification gap. The RTX PRO 4500 uses 32 GB of GDDR7 on a 256-bit bus, reaching 896.0 GB/s. The LX PRO has 24 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The NVIDIA card provides 2.07x the memory bandwidth, a factor that will dominate large dataset and high-resolution texture workloads.

Architecture Differences

The NVIDIA RTX PRO 4500 uses the GB203 chip built on TSMC's 5 nm process with a 378 mm² die and 45,600 million transistors. Its transistor density reaches 120.6 million per mm². The architecture is Blackwell 2.0 from the Blackwell PRO W (x000) generation, succeeding Workstation Ada. It was released on 2025-03-17.

The Lisuan Tech LX PRO uses the 7G105 chip on TSMC's 6 nm process, with transistor count and die size listed as unknown. Its architecture is called TrueGPU, from the 7G100 generation. It has a later release date of 2026-03-16. Neither card lists a launch MSRP in the database.

The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT cores or tensor cores listed. The absence of RT core and tensor core data for the LX PRO means ray tracing and AI acceleration capabilities cannot be quantified for that card.

Clock behavior differs significantly. The RTX PRO 4500 has a base clock of 1635 MHz and a boost clock of 2407 MHz. The LX PRO has neither base nor boost clocks recorded, only a memory clock of 2250 MHz for 18 Gbps effective. The NVIDIA card's memory runs at 1750 MHz for 28 Gbps effective.

The RTX PRO 4500 supports PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. Display output also differs: the NVIDIA card has 4x DisplayPort 2.1b, the LX PRO has 4x DisplayPort 1.4a. The RTX PRO 4500 lists Vulkan 1.4 support, while the LX PRO lists Vulkan 1.3. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

Power specifications show the RTX PRO 4500 at 200 W TDP and the LX PRO at 225 W TDP. Both use a single 16-pin power connector and recommend a 550 W power supply. Both are dual-slot cards.

Physical dimensions differ: the RTX PRO 4500 is 267 mm long, 111 mm tall, and 40 mm wide. The LX PRO is 248 mm long, 118 mm tall, and 48 mm wide. The LX PRO is shorter but taller and thicker.

The Verdict

The data shows a clear split between raw compute and specialized features. The RTX PRO 4500 leads in every measured compute category: FP32 (50.53 versus 24.58 TFLOPS), pixel rate (269.6 versus 192.0 GPixel/s), texture rate (789.5 versus 384.0 GTexel/s), and memory bandwidth (896.0 versus 432.0 GB/s). It also has more shading units, TMUs, ROPs, and the only recorded RT and tensor cores.

The LX PRO counters with a higher TDP (225 W versus 200 W), a later release date (2026-03-16 versus 2025-03-17), and FP16 performance that nearly matches the NVIDIA card (49.15 versus 50.53 TFLOPS) thanks to its 2:1 FP16 ratio. Its 6 nm process node is older than the 5 nm node used for the RTX PRO 4500.

For workloads that depend on FP32 throughput, memory bandwidth, or ray tracing, the RTX PRO 4500 is the stronger choice based on the recorded specifications. For FP16-heavy workloads where the 2:1 ratio matters, the LX PRO narrows the gap considerably. The absence of benchmark scores and nearest rival data means these conclusions rest entirely on specification comparisons.

The RTX PRO 4500 is the more complete workstation card: it has tensor cores, RT cores, newer PCIe generation, newer display outputs, and more memory. The LX PRO is a simpler design with fewer features but a lower power draw per FP32 unit of work, since its TDP is only 12.5% higher while its FP32 output is less than half.

Where Each One Wins

The RTX PRO 4500 wins in FP32 compute, delivering 50.53 TFLOPS versus 24.58 TFLOPS, which suits general GPU compute, simulation, and single-precision scientific workloads. It also wins in memory bandwidth at 896.0 GB/s, a decisive factor for large datasets, high-resolution textures, and multi-GPU rendering pipelines. Its 32 GB GDDR7 capacity exceeds the LX PRO's 24 GB GDDR6, providing more headroom for large model and scene data.

The RTX PRO 4500 wins in texture and pixel throughput, with 789.5 GTexel/s and 269.6 GPixel/s versus 384.0 GTexel/s and 192.0 GPixel/s. This favors rasterization-heavy workloads and high-detail 3D rendering. Its 82 RT cores and 328 tensor cores give it capabilities the LX PRO cannot match in ray-traced rendering and AI-accelerated tasks.

The LX PRO wins in FP16 efficiency. With a 2:1 FP16 ratio, it reaches 49.15 TFLOPS, nearly matching the RTX PRO 4500's 50.53 TFLOPS, while using a simpler architecture. This narrows the gap for FP16 compute tasks. The LX PRO also has a shorter physical length (248 mm versus 267 mm), which may fit smaller chassis, and a later release date.

The LX PRO uses less memory bandwidth per watt, since its 432.0 GB/s at 225 W TDP compares to 896.0 GB/s at 200 W for the NVIDIA card, but that advantage is not meaningful when the absolute bandwidth is half. The RTX PRO 4500 delivers more bandwidth at lower power, making it the more efficient card in absolute terms. The LX PRO's only clear efficiency win is FP16 per watt, where its 2:1 ratio offsets its lower raw throughput.
