NVIDIA B200 SXM6 vs Lisuan Tech LX ULTRA Comparison

NVIDIA B200 SXM6 and Lisuan Tech LX ULTRA occupy different ends of the server and workstation GPU spectrum, with the former built for massive parallel compute in AI data centers and the latter designed as a more conventional graphics and compute card for professional workstations. The database records no overlapping benchmark scores for these two parts, so the analysis below relies entirely on the architectural and specification data captured for each product.

Architecture Differences

The NVIDIA B200 SXM6 uses the GB100 chip built on the Blackwell architecture, fabricated on a 5 nm process at TSMC. The die measures 1628 mm² and contains 208,000 million transistors, yielding a transistor density of 127.8 million per square millimeter. This is a server-class part from the Server Blackwell generation, released in October 2024. The B200 uses HBM3e memory with 180 GB capacity on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The memory clock is 2000 MHz with 8 Gbps effective data rate.

Lisuan Tech LX ULTRA uses the 7G105 chip based on the TrueGPU architecture, from the 7G100 generation, fabricated on a 6 nm process at TSMC. Transistor count and die size are not recorded in the database. The LX ULTRA uses 24 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. Memory clock is 2250 MHz with 18 Gbps effective data rate.

The B200 has 18,944 shading units, 592 texture mapping units, and 24 raster output units. It includes 592 tensor cores.

Where Each One Wins

The NVIDIA B200 SXM6 wins in raw compute throughput and memory capacity. Its FP32 rate of 69.34 TFLOPS is more than double the 24.58 TFLOPS of the LX ULTRA. The B200 also has 180 GB of HBM3e memory versus 24 GB of GDDR6, giving it nearly 19 times the memory bandwidth. This makes the B200 the clear choice for large-scale AI training, inference, and scientific simulation where massive datasets must reside in GPU memory and be accessed at extreme speeds. The 592 tensor cores indicate a hardware path for matrix operations, though the database does not record tensor core counts for the LX ULTRA.

The B200 also leads in texture throughput with 1,083.4 GTexel/s, which matters for volume rendering and texture-heavy compute workloads. Its 208,000 million transistors on a 1628 mm² die provide a substantial compute substrate. The B200 is a server module with no display outputs, meaning it is intended for headless compute nodes in data centers.

The Lisuan Tech LX ULTRA wins in rasterization throughput and display capability. Its 192.0 GPixel/s pixel rate is more than four times the 43.92 GPixel/s of the B200. The LX ULTRA has 96 ROPs versus 24 ROPs on the B200, which directly affects fill-rate-bound rendering workloads. With 4x DisplayPort 1.4a outputs, the LX ULTRA can drive multiple monitors and function as a standard workstation GPU for CAD, video editing, and OpenGL-based applications.

The LX ULTRA also wins on power efficiency per the recorded data. At 225 W TDP, it draws far less than the 1000 W TDP of the B200. Its FP16 rate of 49.15 TFLOPS is respectable, and its 2:1 FP16 ratio suggests a design optimized for mixed-precision workloads where FP16 is sufficient. The LX ULTRA supports PCIe 4.0, which is older than the B200's PCIe 6.0, but this is less relevant for a card in the 225 W class.

The LX ULTRA is the only one of the two with any graphics API support. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 are recorded for the LX ULTRA, while the B200 shows N/A for all three. This means the B200 cannot run conventional graphics applications, while the LX ULTRA can serve as a full graphics solution.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs, and neither product has recorded benchmark scores or nearest rival data. Both have a percentile ranking of 50 against all GPUs, and both have an average benchmark score of 0 in the current records. This means there are no direct measured comparisons available.

The specification data provides the only basis for comparison. The B200 leads in FP32 compute by a margin of 44.76 TFLOPS, since 69.34 minus 24.58 equals 44.76.

Texture mapping units differ by 400, with 592 on the B200 and 192 on the LX ULTRA.

The LX ULTRA leads in pixel rate by 148.08 GPixel/s, since 192.0 minus 43.92 equals 148.08. ROP count is 96 on the LX ULTRA versus 24 on the B200, a 72 ROP advantage. Memory bandwidth favors the B200 by 7.76 TB/s, as 8.19 TB/s minus 0.432 TB/s equals 7.758 TB/s, recorded as 8.19 TB/s versus 432.0 GB/s.
