Architecture Differences

The NVIDIA B300 is built on the Blackwell Ultra architecture, specifically the GB110 chip, fabricated on a 5 nm process at TSMC. It belongs to the Server Blackwell (Bxx) generation. The die integrates 104,000 million transistors. The B300 is a SXM module, which means it is designed for server chassis rather than standalone desktop installation. It has no display outputs, reinforcing its purpose as an accelerator for data center workloads.

The Lisuan Tech LX MAX uses the TrueGPU architecture with the 7G106 chip, fabricated on a 6 nm process at TSMC. It belongs to the 7G100 generation. The transistor count and die size are listed as unknown in the database. The LX MAX is a dual-slot PCIe card with a length of 248 mm, height of 118 mm, and width of 48 mm. It includes 4x DisplayPort 1.4a outputs, making it a graphics-capable card.

The B300’s memory configuration uses HBM3e with a 4096-bit bus width, whereas the LX MAX uses GDDR6 with a 192-bit bus. The B300 has 18,944 shading units, 592 TMUs, and 24 ROPs. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The B300 includes 592 tensor cores, while the LX MAX has no tensor cores listed. This difference indicates the B300 is optimized for AI and tensor workloads, while the LX MAX relies on conventional shader-based compute.

Clock behavior also differs sharply. The B300 has a base clock of 1665 MHz and a boost clock of 2032 MHz, with memory running at 2000 MHz (8 Gbps effective). The LX MAX has no base or boost clock listed, but its memory runs at 2250 MHz (18 Gbps effective). The B300’s pixel rate is 48.77 GPixel/s, while the LX MAX achieves 192.0 GPixel/s. The B300’s texture rate is 1,202.9 GTexel/s versus 384.0 GTexel/s for the LX MAX.

The B300 uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. The B300 has a TDP of 1400 W and a suggested PSU of 1800 W. The LX MAX has a TDP of 225 W and a suggested PSU of 550 W, with a single 16-pin power connector. The B300’s release date is 2025-09-10, and its predecessor is Server Hopper with successor Server Rubin. The LX MAX’s release date is 2026-03-16, with no predecessor or successor listed.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results for these two products, and neither has an average benchmark score or nearest rivals listed. Both share a percentileVsAllGpus of 50, indicating median standing in the overall GPU distribution, but the absence of measured scores means direct performance comparisons must rely on specification differences.

The most decisive gap is memory bandwidth. The B300 delivers 4.10 TB/s against the LX MAX’s 432.0 GB/s. That is a 9.5-fold advantage. For memory-bound workloads, such as large model inference or high-resolution rendering, this difference will dominate. The B300 also has 144 GB of memory versus 12 GB, a 12-fold capacity lead. This allows the B300 to hold far larger datasets and models on-device, reducing reliance on host memory transfers.

Compute throughput follows a similar pattern. The B300’s FP32 rate is 76.99 TFLOPS, which is 3.1 times the LX MAX’s 24.58 TFLOPS. In FP16, the B300 reaches 1,231.8 TFLOPS (16:1), which is 25.1 times the LX MAX’s 49.15 TFLOPS (2:1). The B300’s tensor cores, 592 of them, enable this FP16 advantage, while the LX MAX has no tensor core count listed. For AI training or inference with mixed-precision arithmetic, the B300’s lead is substantial.

Texture throughput favors the B300 as well. Its texture rate is 1,202.9 GTexel/s versus 384.0 GTexel/s for the LX MAX, a 3.1-fold advantage. However, the pixel rate reverses this trend. The LX MAX renders 192.0 GPixel/s, which is 3.9 times the B300’s 48.77 GPixel/s. This is notable because pixel rate often correlates with rasterization performance at high resolutions. The LX MAX’s 96 ROPs, compared to the B300’s 24 ROPs, explain this inversion.

Memory clock speed also differs. The LX MAX’s memory runs at 18 Gbps effective, more than double the B300’s 8 Gbps effective. But the B300 compensates with a much wider 4096-bit bus versus 192-bit, so the total bandwidth still heavily favors the B300. The LX MAX’s higher per-pin speed does not overcome the bus width deficit.

Shading unit count favors the B300: 18,944 versus 6,144, a 3.1-fold difference. This aligns with the FP32 gap. TMU counts are 592 for the B300 and 192 for the LX MAX, also a 3.1-fold difference. The ROP count is the only major resource where the LX MAX leads, with 96 versus 24, a 4-fold advantage.

The B300’s PCIe 5.0 x16 interface offers twice the per-lane bandwidth of the LX MAX’s PCIe 4.0 x16. For host-to-device transfers, the B300 can move data faster, assuming the platform supports PCIe 5.0. The LX MAX’s PCIe 4.0 is adequate for its 225 W power envelope but limits transfer speed relative to the B300.

The Verdict

The data indicates two products aimed at different segments. The NVIDIA B300 is a server accelerator with massive memory capacity, bandwidth, and FP16 throughput. It has no display outputs, a 1400 W TDP, and a SXM form factor. The Lisuan Tech LX MAX is a dual-slot graphics card with 4x DisplayPort 1.4a, a 225 W TDP, and a 550 W suggested PSU.

For compute-heavy workloads, particularly those using FP16 or tensor operations, the B300 is the stronger choice. Its 1,231.8 TFLOPS FP16 output and 592 tensor cores provide a scale of performance the LX MAX cannot approach. The B300’s 144 GB memory and 4.10 TB/s bandwidth also support large-scale data processing that the LX MAX’s 12 GB and 432.0 GB/s cannot handle.

For rasterization-focused tasks, the LX MAX shows an advantage in pixel throughput. Its 192.0 GPixel/s is nearly 4 times the B300’s rate, and its 96 ROPs suggest stronger fill-rate performance for traditional graphics rendering. The LX MAX also has full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the B300 lists none.

The B300’s FP32 performance, 76.99 TFLOPS, is 3.1 times the LX MAX’s 24.58 TFLOPS. This gap applies to general compute as well, not just mixed precision. The B300 also leads in texture rate by the same ratio. The LX MAX’s higher pixel rate does not compensate for these deficits in most server or scientific workloads.

Power consumption is a major differentiator. The B300 requires 1400 W with an 1800 W suggested PSU, while the LX MAX draws 225 W with a 550 W suggested PSU. Systems without high-capacity power delivery cannot accommodate the B300. The LX MAX’s lower power footprint makes it feasible in standard desktop or workstation builds.

The release dates differ by about six months, with the B300 launching 2025-09-10 and the LX MAX launching 2026-03-16. Both are listed as Active in production status. The B300 has a known predecessor and successor in the database, while the LX MAX has neither.

Users requiring maximum memory and tensor throughput should choose the B300. Users needing display outputs, rasterization speed, or lower system power requirements should choose the LX MAX. The benchmark database contains no head-to-head scores, so these conclusions rest entirely on the recorded specifications.
