NVIDIA RTX PRO 4500 Blackwell Workstation 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 4500 Blackwell Workstation and the Lisuan Tech LX MAX. Both entries carry empty benchmark arrays, zero average scores, and zero wins in the comparison matrix. Consequently, the quantitative verdict must be derived from the specification and architecture fields alone.

The most decisive gap appears in raw compute throughput. The RTX PRO 4500 delivers 50.53 TFLOPS FP32, more than double the LX MAX's 24.58 TFLOPS. That difference is 105.6% higher, a lead that will dominate any shader-bound workload where the FP32 path is the bottleneck. In FP16, the picture changes: the LX MAX reaches 49.15 TFLOPS via a 2:1 ratio, while the RTX PRO 4500 also claims 50.53 TFLOPS but at a 1:1 ratio. The recorded numbers therefore put the NVIDIA card 2.8% ahead in peak FP16, but the architecture note matters: the Lisuan part achieves its figure through packed arithmetic, whereas the NVIDIA part runs FP16 at full rate natively.

Memory bandwidth follows a similar pattern. The RTX PRO 4500 has 896.0 GB/s, the LX MAX 432.0 GB/s. That is a 107.4% advantage for NVIDIA. The bus width differs as well: 256 bit versus 192 bit. The RTX PRO 4500 pairs its wider bus with GDDR7 at 28 Gbps effective, while the LX MAX uses GDDR6 at 18 Gbps effective. For any workload that streams large datasets, such as neural network inference or high-resolution texture sampling, the bandwidth gap will translate directly into frame-time or iteration-time differences.

Pixel and texture rates reinforce the NVIDIA lead. The RTX PRO 4500 posts 269.6 GPixel/s and 789.5 GTexel/s. The LX MAX posts 192.0 GPixel/s and 384.0 GTexel/s. NVIDIA leads by 40.4% in pixel throughput and by 105.6% in texture throughput. The texture rate advantage is particularly large because the RTX PRO 4500 carries 328 TMUs against 192, a 70.8% unit count lead.

Shader resources also favor NVIDIA. The RTX PRO 4500 has 10496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The LX MAX has 6144 shading units, 192 TMUs, 96 ROPs, and no recorded RT or tensor core counts. The shading unit lead is 70.8%. ROPs are closer: 112 versus 96, a 16.7% NVIDIA advantage.

The Verdict

From the recorded data alone, the NVIDIA RTX PRO 4500 Blackwell Workstation is the stronger compute platform in nearly every measurable category. It leads in FP32 throughput, FP16 throughput, memory bandwidth, pixel rate, texture rate, shading units, TMUs, ROPs, RT cores, and tensor cores. The only recorded metric where the LX MAX is not substantially behind is power draw: the Lisuan part has a 225 W TDP versus 200 W for NVIDIA, meaning the NVIDIA card achieves significantly higher performance while consuming 12.5% less power.

The Lisuan Tech LX MAX does hold one structural advantage: its FP16 output is nearly double its FP32 output, which the specification records as 49.15 TFLOPS versus 24.58 TFLOPS. Applications that can exploit packed FP16 math, such as certain inference passes or mixed-precision training, will come closer to the NVIDIA card's FP16 number. But even then, the RTX PRO 4500's 50.53 TFLOPS remains ahead.

The database indicates both cards sit at the 50th percentile among all GPUs, but that percentile is based on zero recorded benchmark scores, so it carries no analytical weight. The verdict rests on the spec sheet: the NVIDIA card is the higher-tier workstation part, and the LX MAX is a mid-range alternative with a narrower feature set and lower peak throughput.

Architecture Differences

The two GPUs come from different architectural lineages. NVIDIA's RTX PRO 4500 uses the GB203 chip on a 5 nm TSMC process, built around the Blackwell 2.0 architecture. It belongs to the Blackwell PRO W (x000) generation. The chip integrates 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm².

Lisuan Tech's LX MAX uses the 7G106 chip on a 6 nm TSMC process, with the architecture labeled TrueGPU and the generation labeled 7G100. The database records the transistor count and die size as unknown, so no density figure exists. The process node is one step behind: 6 nm versus 5 nm.

The feature sets diverge sharply. The RTX PRO 4500 includes 82 RT cores and 328 tensor cores, both recorded explicitly. The LX MAX has no recorded RT core or tensor core counts, which the database leaves as null. This suggests the NVIDIA part is designed for hardware-accelerated ray tracing and tensor operations, while the Lisuan part does not expose those units in the recorded data. The API support reflects the same split: both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the NVIDIA card supports Vulkan 1.4, while the LX MAX stops at Vulkan 1.3.

Display output also differs. The RTX PRO 4500 provides 4x DisplayPort 2.1b, while the LX MAX provides 4x DisplayPort 1.4a. The newer DisplayPort version on the NVIDIA card supports higher bandwidth per connector, which matters for driving multiple high-resolution displays at high refresh rates.

The bus interface differs as well: PCIe 5.0 x16 on the NVIDIA card versus PCIe 4.0 x16 on the LX MAX. This affects host-to-device transfer rates, particularly for workloads that page data in and out of GPU memory frequently.

Specification Differences

The recorded specifications differ across memory, compute, power, and physical dimensions.

Memory: the RTX PRO 4500 has 32 GB of GDDR7 on a 256 bit bus, with 896.0 GB/s bandwidth. The LX MAX has 12 GB of GDDR6 on a 192 bit bus, with 432.0 GB/s bandwidth. The NVIDIA card has 2.67 times the capacity and 2.07 times the bandwidth.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Workstation wins in every recorded performance category. Its 50.53 TFLOPS FP32 makes it the choice for raw compute workloads such as simulation, rendering, and general-purpose GPU compute. Its 896.0 GB/s bandwidth and 32 GB capacity suit large datasets, high-resolution textures, and multi-model inference. The 82 RT cores and 328 tensor cores provide dedicated hardware for ray tracing and tensor operations, which the LX MAX does not record at all. The PCIe 5.0 interface and DisplayPort 2.1b outputs position it for modern workstation workflows with high-bandwidth peripherals and multi-monitor setups. Its lower 200 W TDP adds an efficiency advantage.

The Lisuan Tech LX MAX wins in no recorded performance metric, but it does hold a few structural positions. Its FP16 throughput of 49.15 TFLOPS is close enough to the NVIDIA card's 50.53 TFLOPS to matter in workloads that rely on packed FP16 math. Its 2250 MHz memory clock is higher than the NVIDIA card's 1750 MHz, though the effective bandwidth is still far lower due to the 192 bit bus. Its physical dimensions are shorter (248 mm versus 267 mm) and taller (118 mm versus 111 mm), which may suit certain chassis constraints. The 12 GB memory capacity is smaller, but for workloads that fit within that limit, the LX MAX delivers a substantial portion of the NVIDIA card's FP16 throughput at a lower specification tier.

The data-driven conclusion is straightforward: the RTX PRO 4500 is the superior workstation GPU across all recorded metrics, while the LX MAX offers a narrower, lower-bandwidth alternative with competitive packed FP16 capability and a smaller physical footprint.
