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

The Verdict

The database comparison between the NVIDIA RTX PRO 4500 Blackwell Server and the Lisuan Tech LX PRO shows two distinctly different server-class GPUs. The NVIDIA part targets compute workloads that require maximum FP32 throughput and memory bandwidth, while the Lisuan Tech LX PRO offers a balanced alternative with a larger physical footprint and higher power draw. Based strictly on the recorded specifications, the NVIDIA RTX PRO 4500 delivers more than double the FP32 compute performance (50.70 TFLOPS versus 24.58 TFLOPS) and nearly double the memory bandwidth (800.3 GB/s versus 432.0 GB/s). The Lisuan Tech LX PRO counters with a 2:1 FP16 ratio that matches the NVIDIA card's FP16 output (49.15 TFLOPS versus 50.70 TFLOPS), making it competitive for mixed-precision workloads despite its lower FP32 ceiling. The NVIDIA card is the clear choice for FP32-heavy simulation, rendering, or scientific computing where its 5 nm node and 45,600 million transistors provide a density advantage. The Lisuan Tech LX PRO suits deployments that need DisplayPort outputs and are willing to accept a dual-slot design and 225 W TDP for a lower-spec memory subsystem.

Architecture Differences

The NVIDIA RTX PRO 4500 Blackwell Server uses the GB203 chip built on a 5 nm TSMC process with 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm². Its Blackwell 2.0 architecture belongs to the Server Blackwell (Bxx) generation, and it is positioned as a successor to Server Hopper hardware. The chip includes 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The memory subsystem uses 32 GB of GDDR7 on a 256-bit bus, with a base clock of 1215 MHz and a boost clock of 2415 MHz. The FP16 performance is delivered at a 1:1 ratio with FP32, meaning the card sustains 50.70 TFLOPS for both precisions.

The Lisuan Tech LX PRO uses the 7G105 chip fabricated on a 6 nm TSMC process, though the transistor count and die size are not recorded. Its TrueGPU architecture comes from the 7G100 generation. The chip has 6,144 shading units, 192 TMUs, and 96 ROPs, but no RT cores or tensor cores are listed. Memory is 24 GB of GDDR6 on a 192-bit bus, with a memory clock of 2250 MHz (18 Gbps effective). The FP16 performance is delivered at a 2:1 ratio, producing 49.15 TFLOPS from a 24.58 TFLOPS FP32 baseline. The Lisuan card has no base or boost clock figures recorded, so the only clock reference is the memory speed.

The most significant architectural difference is the RT and tensor core count: the NVIDIA card has 82 RT cores and 328 tensor cores, while the Lisuan Tech part records none. This indicates the NVIDIA card is designed for ray tracing and AI acceleration, whereas the Lisuan card appears to be a pure raster compute device. The NVIDIA card also supports PCIe 5.0 x16, while the Lisuan card uses PCIe 4.0 x16. The NVIDIA card has no display outputs, confirming a server-only role, while the Lisuan card includes 4x DisplayPort 1.4a outputs, allowing direct display connection. The API support is nearly identical, with both cards listing DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the NVIDIA card supports Vulkan 1.4 while the Lisuan card is limited to Vulkan 1.3.

Head-to-Head Benchmarks

The recorded specifications allow for a direct comparison of raw compute and memory throughput. The NVIDIA RTX PRO 4500 delivers 50.70 TFLOPS of FP32 performance, which is 106% higher than the Lisuan Tech LX PRO's 24.58 TFLOPS. This means the NVIDIA card processes more than twice as many single-precision floating-point operations per second, a decisive advantage for physics simulations, fluid dynamics, or any FP32-heavy workload. In FP16, the gap narrows significantly: the NVIDIA card sustains 50.70 TFLOPS at a 1:1 ratio, while the Lisuan card reaches 49.15 TFLOPS at a 2:1 ratio. The NVIDIA card still leads by 3.2%, but the Lisuan card's 2:1 ratio allows it to nearly match the FP16 output despite having 43% fewer shading units (6,144 versus 10,496).

Memory bandwidth is another area of clear NVIDIA dominance. The RTX PRO 4500 reaches 800.3 GB/s through its 32 GB GDDR7 on a 256-bit bus, versus 432.0 GB/s for the Lisuan card's 24 GB GDDR6 on a 192-bit bus. That is an 85% bandwidth advantage for the NVIDIA part, which directly impacts memory-bound operations such as large matrix multiplications or data-intensive inference. The NVIDIA card also has a higher pixel rate (270.5 GPixel/s versus 192.0 GPixel/s) and texture rate (792.1 GTexel/s versus 384.0 GTexel/s). The texture rate difference is particularly stark: the NVIDIA card delivers more than double the texel throughput, reflecting its 328 TMUs versus 192 TMUs.

The Lisuan card does have a few areas of relative strength. Its FP16-to-FP32 ratio of 2:1 means it can match the NVIDIA card's FP16 output with less raw shader hardware, making it a reasonable choice for workloads that predominantly use half precision. The Lisuan card also has a higher memory clock in effective terms (18 Gbps versus 25 Gbps is not directly comparable due to different memory types, but the recorded figures show 2250 MHz versus 1563 MHz). The Lisuan card's display outputs are a functional advantage, as the NVIDIA card has none. However, the NVIDIA card's FP32 lead, memory bandwidth lead, and RT/tensor core presence make it the stronger compute part overall.

Specification Differences
