The Lisuan Tech LX 7G100 is larger at 294 mm (11.6 inches) long, 120 mm (4.7 inches) high, and 49 mm (1.9 inches) wide, using PCIe 4.0 x16.

Architecture Differences

The NVIDIA RTX PRO 4500 Blackwell Server and the Lisuan Tech LX 7G100 diverge sharply at the architectural level. The NVIDIA part is built on the Blackwell 2.0 architecture with the GB203 chip, fabricated on TSMC's 5 nm process. It integrates 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The Lisuan Tech LX 7G100 uses the TrueGPU architecture with the 7G106 chip, fabricated on TSMC's 6 nm process. Its transistor count and die size are not recorded in the database.

The compute resources differ meaningfully. The NVIDIA card houses 10,496 shading units, 328 texture mapping units, 112 ROPs, 82 ray tracing cores, and 328 tensor cores. The Lisuan Tech part has 6,144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing cores or tensor cores listed. This absence of dedicated RT and tensor hardware on the Lisuan Tech side is a significant architectural gap, meaning the NVIDIA card carries specialized silicon for ray tracing and AI acceleration that the Lisuan Tech part lacks entirely.

Memory architecture also separates the two. The NVIDIA RTX PRO 4500 Blackwell Server uses GDDR7 with a 256-bit bus and 800.3 GB/s bandwidth. The Lisuan Tech LX 7G100 uses GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The NVIDIA part also supports PCIe 5.0 x16, while the Lisuan Tech part is limited to PCIe 4.0 x16. The NVIDIA card is single-slot with a 1x 16-pin power connector; the Lisuan Tech card is dual-slot with a 1x 8-pin connector.

The NVIDIA card has no display outputs, positioning it as a compute-only server product. The Lisuan Tech LX 7G100 includes 4x DisplayPort 1.4a outputs, giving it display capability. The NVIDIA part supports Vulkan 1.4, whereas the Lisuan Tech part supports Vulkan 1.3; both share DirectX 12 Ultimate and OpenGL 4.6 support.

Clock behavior also differs. The NVIDIA RTX PRO 4500 Blackwell Server has a base clock of 1215 MHz and a boost clock of 2415 MHz. The Lisuan Tech LX 7G100 has no base or boost clock recorded in the database. The NVIDIA part's pixel rate is 270.5 GPixel/s and texture rate is 792.1 GTexel/s; the Lisuan Tech part records 192.0 GPixel/s and 384.0 GTexel/s respectively.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores for these two GPUs. Both entries show an average benchmark score of 0 and a percentile versus all GPUs of 50. No nearest rivals are listed for either card, and the wins counter shows 0 for both sides.

Despite the absence of measured benchmark data, the specification sheets provide a basis for comparison. The NVIDIA RTX PRO 4500 Blackwell Server delivers 50.70 TFLOPS of FP32, which is more than double the 24.58 TFLOPS of the Lisuan Tech LX 7G100. In FP16, the NVIDIA part again leads with 50.70 TFLOPS versus 49.15 TFLOPS, though the margin is much smaller here. The Lisuan Tech card reaches its FP16 figure via a 2:1 ratio, meaning it likely uses half-rate FP16 execution, while the NVIDIA part sustains a 1:1 ratio.

Memory bandwidth heavily favors the NVIDIA part. At 800.3 GB/s, it offers roughly 85% more bandwidth than the Lisuan Tech card's 432.0 GB/s. This advantage matters for memory-bound workloads such as large dataset processing and high-resolution rendering. The NVIDIA card also has more than double the texture fill rate (792.1 GTexel/s vs 384.0 GTexel/s) and a higher pixel rate (270.5 GPixel/s vs 192.0 GPixel/s).

The Lisuan Tech LX 7G100 does hold advantages in certain areas. Its FP16 performance of 49.15 TFLOPS is close to the NVIDIA card's 50.70 TFLOPS, and it offers display outputs where the NVIDIA part has none. Its larger physical footprint (294 mm vs 267 mm length) and dual-slot design suggest a more substantial cooling solution, though the database shows a higher TDP of 225 W versus 165 W for the NVIDIA part.

The Verdict

The recorded data points to the NVIDIA RTX PRO 4500 Blackwell Server as the stronger compute device. It holds a 2.06x advantage in FP32 throughput, a 1.85x advantage in memory bandwidth, a 2.06x advantage in texture rate, and a 1.41x advantage in pixel rate. It also features ray tracing cores and tensor cores, neither of which appear on the Lisuan Tech LX 7G100. The NVIDIA card supports PCIe 5.0, newer Vulkan, and GDDR7 memory.

The Lisuan Tech LX 7G100 is not without merit. Its FP16 output of 49.15 TFLOPS nearly matches the NVIDIA part's 50.70 TFLOPS, and it provides 4x DisplayPort 1.4a outputs for direct display connection. It also uses a simpler 1x 8-pin power connector, which may integrate into systems not equipped for 16-pin power delivery. Its TDP of 225 W and suggested PSU of 550 W are higher than the NVIDIA card's 165 W and 450 W, respectively.

For server deployments focused on FP32 compute, AI workloads, or memory-heavy tasks, the NVIDIA RTX PRO 4500 Blackwell Server is the clear choice from the data. For systems requiring display outputs or those with an 8-pin power infrastructure, the Lisuan Tech LX 7G100 has the recorded features to serve that role, though its compute ceiling is lower.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Server wins in FP32 compute, delivering 50.70 TFLOPS versus 24.58 TFLOPS for the Lisuan Tech LX 7G100. This advantage extends to texture processing, where the NVIDIA card's 792.1 GTexel/s more than doubles the Lisuan Tech part's 384.0 GTexel/s. Pixel throughput also favors NVIDIA at 270.5 GPixel/s versus 192.0 GPixel/s. Memory bandwidth is another clear win for NVIDIA, with 800.3 GB/s versus 432.0 GB/s, and the NVIDIA card provides 32 GB of GDDR7 versus 12 GB of GDDR6.

The NVIDIA part also wins on efficiency per the recorded TDP. It delivers higher performance at 165 W, while the Lisuan Tech card consumes 225 W. The NVIDIA card's single-slot design and shorter length (267 mm vs 294 mm) make it easier to fit in dense server chassis. Its PCIe 5.0 interface doubles the transfer rate of the Lisuan Tech card's PCIe 4.0. The inclusion of 82 RT cores and 328 tensor cores gives the NVIDIA card dedicated hardware for ray tracing and AI workloads, features entirely absent from the Lisuan Tech card's specification list. Its support for Vulkan 1.4 versus Vulkan 1.3 also provides a newer API level.

The Lisuan Tech LX 7G100 wins in FP16 throughput per the recorded figures, achieving 49.15 TFLOPS, which is close to the NVIDIA card's 50.70 TFLOPS. This near-parity in FP16 makes it viable for workloads that rely primarily on half-precision math. The Lisuan Tech card also provides 4x DisplayPort 1.4a outputs, enabling direct display connection, a capability the NVIDIA card lacks entirely. Its 1x 8-pin power connector may be more compatible with existing power supplies, and its dual-slot cooler with a larger footprint (294 mm length, 120 mm height, 49 mm width) could offer more surface area for heat dissipation, though the database does not include thermal measurements. Its release date of 2026-06-17 places it three months after the NVIDIA card's 2026-03-16 release, making it a more recent entry in the database.
