NVIDIA B300 vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data for the NVIDIA B300 and Lisuan Tech LX PRO contains no direct head-to-head benchmark scores, win counts, or rival percentage deltas. Both entries show zero benchmark entries, zero wins for either side, and no nearest rival data. The percentile ranking for each is identical at 50, indicating that, within the database, neither product has a measured performance advantage over the other based on actual workload results. The absence of comparative metrics means any performance conclusion must rely entirely on the specification sheets, which provide a clear separation in raw compute capabilities.

The NVIDIA B300 delivers 76.99 TFLOPS of FP32 compute and 1,231.8 TFLOPS of FP16 (16:1), while the Lisuan Tech LX PRO provides 24.58 TFLOPS of FP32 and 49.15 TFLOPS of FP16 (2:1). In FP32, the B300 is approximately 3.13 times higher in raw throughput. In FP16, the B300's advantage is substantially larger at 25.06 times, though the ratio difference (16:1 versus 2:1) means these figures are not directly comparable without considering the precision conversion overhead. The B300's texture rate is 1,202.9 GTexel/s versus 384.0 GTexel/s for the LX PRO, a 3.13 times difference that mirrors the FP32 gap. The pixel rate tells a different story: the LX PRO outputs 192.0 GPixel/s while the B300 manages only 48.77 GPixel/s, making the LX PRO nearly four times faster in rasterization throughput. This suggests the B300 is optimized for compute-heavy workloads, while the LX PRO retains a more conventional graphics pipeline.

Memory bandwidth is another decisive separator. The B300 accesses 144 GB of HBM3e across a 4096-bit bus, yielding 4.10 TB/s. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, producing 432.0 GB/s. The B300's bandwidth is 9.49 times higher, and its capacity is 6 times larger. The memory clock rates are listed as 2000 MHz (8 Gbps effective) for the B300 and 2250 MHz (18 Gbps effective) for the LX PRO, but the bus width difference renders the effective bandwidth comparison fully in the B300's favor. The B300's shading unit count is 18,944 versus 6,144 for the LX PRO, and the TMU counts are 592 versus 192, both exactly 3.08 times higher for the NVIDIA part. The ROP count is where the LX PRO leads substantially: 96 versus 24, a 4 times advantage that explains its higher pixel throughput.

Architecture Differences

The NVIDIA B300 is built on the Blackwell Ultra architecture, specifically the GB110 chip, and belongs to the Server Blackwell (Bxx) generation. The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip, part of the 7G100 generation. These are fundamentally different design philosophies. The B300 is a server-oriented accelerator with no display outputs, an SXM Module slot width, and a 1400 W power draw. The LX PRO is a dual-slot, PCIe 4.0 add-in card with 4x DisplayPort 1.4a outputs, a 16-pin power connector, and a 225 W power draw. The B300's architecture is designed for dense compute in data center environments, while the LX PRO retains a full graphics output capability.

The transistor count for the B300 is listed at 104,000 million, while the LX PRO's transistor count is unknown. The process node difference is small, 5 nm versus 6 nm, both at TSMC. The B300 integrates 592 tensor cores, while the LX PRO lists no tensor cores. The B300's FP16 ratio of 16:1 indicates a dedicated tensor core path that vastly accelerates mixed-precision workloads, while the LX PRO's FP16 ratio of 2:1 suggests a more conventional compute path where FP16 is simply a lower-precision version of FP32. The B300 also has no listed API support for DirectX, OpenGL, or Vulkan, whereas the LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. This confirms the B300 is not intended for graphics rendering, while the LX PRO is a fully featured graphics card.

The memory subsystem differs in type, capacity, and bus width. HBM3e on the B300 provides 4.10 TB/s, while GDDR6 on the LX PRO provides 432.0 GB/s. The LX PRO's 192-bit bus is common for mid-range graphics cards, while the B300's 4096-bit bus is a hallmark of high-bandwidth compute accelerators. The B300 has no power connector listed, as it uses an SXM module interface, while the LX PRO uses a single 16-pin connector. The suggested PSU for the B300 is 1800 W, while the LX PRO recommends 550 W. The release dates are also distinct: the B300 entered production in September 2025, and the LX PRO followed in March 2026.

The Verdict

The data indicates two products with opposite design goals. The NVIDIA B300 is a server compute accelerator with a 1400 W power envelope, no display outputs, and massive memory bandwidth. It delivers 76.99 TFLOPS of FP32 and 1,231.8 TFLOPS of FP16, with 592 tensor cores. Its memory subsystem of 144 GB HBM3e at 4.10 TB/s is unmatched by the LX PRO's 24 GB GDDR6 at 432.0 GB/s. The B300 is the choice for compute-bound workloads that require high FP32 throughput, tensor core acceleration, and very large memory capacity, provided the host system can supply 1800 W and accommodate an SXM module.

The Lisuan Tech LX PRO is a conventional graphics card with a 225 W power draw, dual-slot cooling, and 4x DisplayPort 1.4a outputs. Its 192.0 GPixel/s pixel rate and 96 ROPs make it substantially faster in rasterization. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, making it suitable for graphics rendering applications that the B300 cannot handle. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 are lower, but its 550 W suggested PSU and standard PCIe 4.0 x16 interface allow for easier system integration. The LX PRO is the appropriate choice for graphics output, display-driven workloads, or applications where the 1400 W power requirement of the B300 is prohibitive.

The benchmark database contains no direct performance measurements for either product. Both share a 50th percentile ranking. The specification sheets, however, show a clear separation: the B300 dominates in compute throughput, memory bandwidth, and capacity, while the LX PRO dominates in pixel fill rate, ROP count, and display connectivity. Users requiring server-grade compute acceleration should select the B300. Users requiring a graphics card with standard outputs and lower power consumption should select the LX PRO. The absence of benchmark scores leaves the specification comparison as the only quantitative basis for this decision.
