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

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the NVIDIA RTX PRO 4500 Blackwell Server or the Lisuan Tech LX MAX. Both entries show an average benchmark score of zero, with zero wins recorded for each side in the head-to-head comparison table. This absence of runtime data means the comparison must rely entirely on the architectural specifications and recorded hardware parameters.

The raw compute figures do provide a clear separation. The NVIDIA part delivers 50.70 TFLOPS of FP32 throughput, while the Lisuan Tech LX MAX reaches 24.58 TFLOPS. That places the NVIDIA adapter at approximately 2.06 times the single-precision compute of its rival. In FP16 workloads, the two cards align differently: the RTX PRO 4500 sustains 50.70 TFLOPS with a 1:1 ratio, while the LX MAX reaches 49.15 TFLOPS via a 2:1 ratio. The FP16 numbers are nearly identical, a notable outcome given the substantial gap in FP32.

Texture and pixel processing follow the same pattern. The NVIDIA GPU records 792.1 GTexel/s against 384.0 GTexel/s for the Lisuan part, a 2.06x advantage. Pixel rates sit at 270.5 GPixel/s versus 192.0 GPixel/s, a 1.41x margin. Memory bandwidth tells a similar story: 800.3 GB/s on the NVIDIA side versus 432.0 GB/s on the Lisuan, a 1.85x difference.

The one area where the Lisuan Tech LX MAX pulls ahead on paper is power draw. The NVIDIA part carries a 165 W TDP, while the Lisuan part consumes 225 W. That is a 60 W higher thermal envelope for the slower card. The NVIDIA GPU also fits a single-slot form factor with a 267 mm length, 111 mm height, and 40 mm width. The Lisuan card occupies a dual-slot footprint at 248 mm long, 118 mm high, and 48 mm wide.

Where Each One Wins

For compute-heavy workloads that rely on FP32 throughput, the NVIDIA RTX PRO 4500 Blackwell Server is the clear choice. Its 50.70 TFLOPS doubles the Lisuan Tech LX MAX's 24.58 TFLOPS. Any application that scales with raw single-precision math, such as simulation, physics, or general-purpose GPU compute, will favor the NVIDIA part by a wide margin.

Memory capacity and bandwidth also favor the NVIDIA card. The RTX PRO 4500 carries 32 GB of GDDR7 across a 256 bit bus, yielding 800.3 GB/s. The Lisuan part offers 12 GB of GDDR6 on a 192 bit bus, reaching 432.0 GB/s. For large datasets, model weights, or rendering scenes that exceed 12 GB, the NVIDIA card provides both higher capacity and faster movement of data. The 20 GB difference in VRAM is substantial. Workloads that fit within 12 GB but demand bandwidth will still see a 1.85x advantage on the NVIDIA side.

The Lisuan Tech LX MAX holds advantages in two specific areas. First, its FP16 throughput of 49.15 TFLOPS is within 3% of the NVIDIA card's 50.70 TFLOPS. For mixed-precision workflows where FP16 is acceptable, the Lisuan part delivers nearly the same compute at a lower hardware cost. Second, the LX MAX provides display outputs. It has 4x DisplayPort 1.4a connectors, while the NVIDIA RTX PRO 4500 lists no display outputs at all. Any deployment requiring direct video output must use the Lisuan card or add a separate display adapter.

The Lisuan card also supports a broader API set in one respect: it lists Vulkan 1.3 support, while the NVIDIA part lists Vulkan 1.4. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The newer Vulkan revision on the NVIDIA side indicates more recent driver-level API coverage.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA RTX PRO 4500 uses the GB203 chip based on Blackwell 2.0 architecture, part of the Server Blackwell (Bxx) generation. It is built on a 5 nm process at TSMC with 45,600 million transistors on a 378 mm² die. That yields a transistor density of 120.6M per mm². The Lisuan Tech LX MAX uses the 7G106 chip under the TrueGPU architecture, part of the 7G100 generation, also fabricated by TSMC but on a 6 nm process. Its transistor count and die size are not recorded in the database.

The compute pipelines differ significantly. The NVIDIA GPU contains 10,496 shading units, 328 TMUs, and 112 ROPs. It also includes 82 RT cores and 328 tensor cores. The Lisuan part has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT cores or tensor cores listed. This structural difference means the NVIDIA card can handle hardware-accelerated ray tracing and tensor operations, while the Lisuan card has no such dedicated units on record.

Memory subsystems diverge as well. The NVIDIA card uses GDDR7 memory at 1563 MHz with 25 Gbps effective speed, delivering 32 GB across a 256 bit interface. The Lisuan card uses GDDR6 at 2250 MHz with 18 Gbps effective speed, delivering 12 GB across a 192 bit interface. The newer GDDR7 standard and wider bus explain the bandwidth gap.

The interface and power delivery also differ. The NVIDIA card uses PCIe 5.0 x16, while the Lisuan card uses PCIe 4.0 x16. Both use a single 16-pin power connector. The NVIDIA card recommends a 450 W power supply, while the Lisuan card recommends 550 W. The NVIDIA part consumes 165 W TDP; the Lisuan part consumes 225 W. The NVIDIA card is single-slot, while the Lisuan card is dual-slot.

The NVIDIA card has no display outputs, making it a compute-only accelerator. The Lisuan card provides 4x DisplayPort 1.4a outputs, allowing direct display connectivity. Both cards are listed as Active production status with the same release date of 2026-03-16. The NVIDIA card lists a predecessor (Server Hopper) and successor (Server Rubin), while the Lisuan card has neither.

The Verdict

The data points to a decisive split in roles. For any workload that depends on FP32 compute, memory bandwidth, or memory capacity, the NVIDIA RTX PRO 4500 Blackwell Server is the stronger part. Its 50.70 TFLOPS FP32 output doubles the Lisuan Tech LX MAX's 24.58 TFLOPS. Its 800.3 GB/s bandwidth is 1.85x the Lisuan figure. Its 32 GB VRAM is 2.67x the Lisuan capacity. These are large, structural advantages that no software optimization can overcome.

The Lisuan Tech LX MAX does hold specific merits. Its FP16 throughput of 49.15 TFLOPS nearly matches the NVIDIA card's 50.70 TFLOPS. For workloads that use FP16 exclusively, the performance difference is minimal. The Lisuan card also includes 4x DisplayPort 1.4a outputs, making it a self-contained solution for tasks that require video output. The NVIDIA card cannot drive a display without additional hardware.

The power envelope favors the NVIDIA part. At 165 W TDP versus 225 W, the NVIDIA card delivers more compute per watt. The NVIDIA card also occupies a single slot, which matters for dense server configurations. The Lisuan card requires two slots and a higher recommended power supply.

The absence of recorded benchmark scores means these conclusions rest on specification-level analysis rather than measured runtime data. The database shows zero wins for either card in the head-to-head table, and both sit at the 50th percentile against all GPUs with zero average benchmark score. Buyers should treat the architectural differences as the primary decision factors until runtime measurements become available.

For compute-dense environments where FP32 accuracy, large memory pools, and high bandwidth are critical, the NVIDIA RTX PRO 4500 Blackwell Server is the appropriate selection. For workloads that tolerate FP16 precision and require direct display output, the Lisuan Tech LX MAX offers a viable alternative with near-parity FP16 throughput. The choice hinges on the precision requirements and display needs of the target application.
