The Verdict

The data clearly favors the NVIDIA RTX PRO 4500 Blackwell for almost every measurable metric. It has double the FP32 throughput, more than double the memory bandwidth, and higher pixel and texture rates. The LX PRO is a newer product (release date of 2026-03-16 versus 2025-03-17), but its specifications place it in a lower performance tier. The RTX PRO 4500 sits at the 76th percentile among all GPUs in the database, while the LX PRO sits at the 50th percentile with no recorded benchmark scores.

For users who need maximum compute throughput, the RTX PRO 4500 is the clear choice. For those who prioritize a smaller physical footprint, the LX PRO has a shorter length (248 mm versus 267 mm) and slightly higher height (118 mm versus 111 mm), but this does not compensate for its lower raw performance. The RTX PRO 4500 also offers more VRAM (32 GB versus 24 GB), which matters for large datasets. The LX PRO has no benchmark results in the database, so its real-world performance cannot be verified; the RTX PRO 4500 has a recorded average benchmark score of 31532.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two cards, and the LX PRO has no individual benchmark scores listed. However, the RTX PRO 4500 has multiple recorded scores that establish its performance baseline.

In 3DMark Steel Nomad DX12, the RTX PRO 4500 scores 7025. In Geekbench Vulkan, it scores 221768. Passmark results include a G3D score of 33360, a GPU compute score of 19255, and a G2D score of 1336. DirectX-specific Passmark scores are 204 for DX10, 320 for DX11, 119 for DX12, and 397 for DX9. The average benchmark score across all tests is 31532.

Given the LX PRO has no scores, the comparison relies on specification-derived performance. The RTX PRO 4500's FP32 output of 50.53 TFLOPS is 105% higher than the LX PRO's 24.58 TFLOPS. Its texture rate of 789.5 GTexel/s is 106% higher than the LX PRO's 384.0 GTexel/s. The pixel rate advantage is 40% (269.6 GPixel/s versus 192.0 GPixel/s). Memory bandwidth is 107% higher on the NVIDIA card (896.0 GB/s versus 432.0 GB/s).

The nearest rivals in the database for the RTX PRO 4500 include the NVIDIA TITAN RTX with an average score of 31676 and a delta of -0.5%, the NVIDIA GRID M60-1Q with 31220 and a delta of 1%, the NVIDIA Quadro M5000 with 31206 and a delta of 1%, and the Intel Arc Pro A30M with 31894 and a delta of -1.1%. This indicates the RTX PRO 4500 performs within a narrow band around 31500 points, slightly behind the Intel Arc Pro A30M and slightly ahead of the TITAN RTX.

Specification Differences

The two cards differ across nearly every core specification. The RTX PRO 4500 uses 10496 shading units, 328 TMUs, and 112 ROPs. The LX PRO uses 6144 shading units, 192 TMUs, and 96 ROPs. The NVIDIA card has 82 RT cores and 328 tensor cores, while the LX PRO lists no RT or tensor core counts.

Memory configuration differs substantially: 32 GB GDDR7 versus 24 GB GDDR6, 256-bit versus 192-bit bus, 896.0 GB/s versus 432.0 GB/s bandwidth. The memory clock is 1750 MHz (28 Gbps effective) on the RTX PRO 4500 versus 2250 MHz (18 Gbps effective) on the LX PRO.

The RTX PRO 4500 has a base clock of 1635 MHz and a boost clock of 2407 MHz. The LX PRO has no base or boost clock listed. Power draw differs slightly: 200 W versus 225 W. Both are dual-slot cards with a single 16-pin connector and a 550 W suggested PSU.

Bus interfaces differ: PCIe 5.0 x16 for the RTX PRO 4500 versus PCIe 4.0 x16 for the LX PRO. Display outputs are also different: 4x DisplayPort 2.1b versus 4x DisplayPort 1.4a. Physical dimensions vary: the RTX PRO 4500 is 267 mm long, 111 mm high, and 40 mm wide; the LX PRO is 248 mm long, 118 mm high, and 48 mm wide.

Architecture Differences

The RTX PRO 4500 uses the GB203 chip built on the Blackwell 2.0 architecture at a 5 nm TSMC process node. It integrates 45,600 million transistors on a 378 mm² die with a density of 120.6M / mm². Its FP16 performance matches FP32 at 50.53 TFLOPS (1:1 ratio), indicating full-rate half-precision compute.

The LX PRO uses the 7G105 chip built on the TrueGPU architecture at a 6 nm TSMC process node. Its transistor count and die size are unknown. Its FP16 performance is 49.15 TFLOPS (2:1 ratio), meaning half-precision runs at twice the rate of FP32. This suggests the LX PRO is optimized for workloads that can use FP16, but its absolute throughput still trails the RTX PRO 4500 in both precision modes.

The RTX PRO 4500 supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The NVIDIA card has dedicated RT cores and tensor cores, which are absent from the LX PRO's listed specifications. The LX PRO's 6 nm process is a newer node, but without transistor data, its architectural efficiency cannot be quantified.

Where Each One Wins

The RTX PRO 4500 wins in every performance category where data exists. It delivers higher FP32 throughput, higher FP16 throughput, higher texture rate, higher pixel rate, and higher memory bandwidth. It also has more VRAM, more shading units, more TMUs, more ROPs, and dedicated RT and tensor cores. Its PCIe 5.0 interface provides double the bandwidth of the LX PRO's PCIe 4.0. Its DisplayPort 2.1b outputs support newer display standards than the LX PRO's DisplayPort 1.4a.

The LX PRO has no recorded benchmark wins. Its only advantages are a lower power draw per the TDP specification? No, the LX PRO draws 225 W versus 200 W, so that is not an advantage. Its physical length is shorter (248 mm versus 267 mm), which may fit in tighter chassis. Its FP16 ratio of 2:1 means it can process half-precision at 49.15 TFLOPS, which is close to the RTX PRO 4500's 50.53 TFLOPS FP16, but still lower. Its 6 nm process node is newer than the 5 nm node, but this is not reflected in any performance metric.

For scenarios requiring maximum FP32 compute, the RTX PRO 4500 is the only choice. For FP16-heavy workloads, the LX PRO is closer but still behind. For memory-intensive tasks, the RTX PRO 4500's 896.0 GB/s bandwidth and 32 GB capacity are decisive. For users with space constraints, the LX PRO's shorter length is a minor consideration, but the RTX PRO 4500's dual-slot width is 40 mm versus 48 mm for the LX PRO, making the NVIDIA card thinner as well. The data supports the RTX PRO 4500 as the stronger card in every measurable dimension.
