NVIDIA B300 SXM6 AC vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database contains a single OpenCL benchmark for the NVIDIA B300 SXM6 AC, scoring 369,831 points. This places it in the 100th percentile among all GPUs, meaning it outperforms every other recorded device in the database. The Lisuan Tech LX PRO has no recorded benchmark scores, so direct numerical comparison is impossible. However, the B300's score can be contextualized against its nearest rivals, all of which it surpasses by significant margins.

The B300 leads the NVIDIA B200 by 7%, a modest but meaningful gap for a generation-over-generation comparison. Against the NVIDIA H200 NVL, the B300 is 10.4% ahead. The AMD Instinct MI300X trails by 16.3%, and the NVIDIA L40S falls 25% behind. These deltas show a consistent scaling pattern: the B300 does not merely edge out its competitors, it establishes a clear tier of performance above each one. The largest gap, 25% over the L40S, suggests that the B300 occupies a different performance class entirely, likely due to its massive memory subsystem and compute configuration.

The LX PRO, with zero recorded scores and an average benchmark score of 0, cannot be placed on the same scale. Its percentile rank of 50 is a default position, not a measured result. Readers should interpret this as "no data available" rather than a true midpoint performance. The absence of benchmarks means any head-to-head analysis must rely on architectural specifications and feature sets, which are discussed in the following sections.

Architecture Differences

The two devices come from fundamentally different design philosophies. The NVIDIA B300 SXM6 AC uses the GB110 chip, built on the Blackwell Ultra architecture, and belongs to the Server Blackwell (Bxx) generation. It is fabricated on a 5 nm process at TSMC, with 208,000 million transistors packed into a 1628 mm² die, yielding a transistor density of 127.8 million per square millimeter. This is a massive, compute-oriented silicon designed for data center workloads.

The Lisuan Tech LX PRO uses the 7G105 chip, based on the TrueGPU architecture, part of the 7G100 generation. It is also manufactured by TSMC, but on a 6 nm process. Its transistor count and die size are listed as unknown, and no transistor density is recorded. This lack of data makes process-level comparison incomplete, but the node difference (5 nm vs 6 nm) suggests the B300 uses a more advanced manufacturing process, which typically enables higher transistor density and lower power per transistor.

Memory architecture diverges sharply. The B300 carries 288 GB of HBM3e memory across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, providing 432.0 GB/s. The B300 has 19 times the memory capacity and roughly 19 times the bandwidth, a gap that will dominate any memory-bound workload. Memory clock rates also differ: the B300 runs at 2000 MHz with 8 Gbps effective, while the LX PRO runs at 2250 MHz with 18 Gbps effective. The LX PRO's higher per-pin speed does not compensate for its narrower bus and smaller capacity.

Compute resources show a similar imbalance. The B300 has 18,944 shading units, 592 TMUs, and 24 ROPs, plus 592 tensor cores. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs, with no tensor cores listed. The B300's shading unit count is roughly three times higher, and its tensor core presence indicates AI-oriented capability that the LX PRO lacks entirely. Pixel rate favors the LX PRO at 192.0 GPixel/s versus the B300's 48.77 GPixel/s, and texture rate favors the B300 at 1,202.9 GTexel/s versus 384.0 GTexel/s. The LX PRO's higher pixel rate suggests it may be better suited to rasterization-heavy tasks, while the B300 dominates texture throughput.

FP32 compute is 76.99 TFLOPS for the B300 versus 24.58 TFLOPS for the LX PRO. FP16 performance is identical to FP32 on the B300 (1:1 ratio), while the LX PRO achieves 49.15 TFLOPS at a 2:1 ratio. Even at FP16, the LX PRO remains below the B300's FP32 figure. Power consumption reflects the performance gap: the B300 draws 1100 W with a suggested PSU of 1500 W, while the LX PRO draws 225 W with a 550 W suggested PSU. The B300 is an SXM module, requiring a server chassis, while the LX PRO is a dual-slot card with a 16-pin power connector and display outputs (4x DisplayPort 1.4a). The B300 has no display outputs.

Bus interfaces differ as well: PCIe 6.0 x16 for the B300, PCIe 4.0 x16 for the LX PRO. API support is complete for the LX PRO (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.3), while the B300 lists N/A for all APIs, reinforcing its compute-only role. The LX PRO also has physical dimensions recorded (248 mm length, 118 mm height, 48 mm width), while the B300 has none, as it is a module rather than a card.

The Verdict

The data indicates two devices with almost no overlap in intended use. The NVIDIA B300 SXM6 AC is a data center accelerator with top-tier compute, massive memory, and no display output. Its benchmark score places it at the 100th percentile, and it leads every recorded rival by at least 7%. The Lisuan Tech LX PRO is a workstation or consumer-oriented card, with display outputs, standard API support, and a much lower power envelope. It has no recorded benchmarks, so its performance cannot be verified.

For workloads requiring maximum compute throughput, memory capacity, or AI tensor operations, the B300 is the only choice supported by data. Its 288 GB HBM3e and 8.19 TB/s bandwidth handle datasets that would overflow the LX PRO's 24 GB GDDR6. For tasks that need rasterization, pixel fill, or display output, the LX PRO is the functional option, though its actual performance is unmeasured. The B300's lack of display outputs and API support makes it unsuitable for interactive graphics.

The 1100 W TDP of the B300 requires server infrastructure, while the LX PRO's 225 W TDP fits a standard desktop. The B300's 5 nm process and 208,000 million transistors indicate a far more complex silicon, but the LX PRO's 6 nm process with unknown transistor count prevents a direct density comparison. Release dates differ by about six months: the B300 launched in September 2025, the LX PRO in March 2026. Both are listed as active production.

Where Each One Wins

The NVIDIA B300 SXM6 AC wins in every compute-heavy category recorded. Its FP32 throughput of 76.99 TFLOPS is more than three times the LX PRO's 24.58 TFLOPS. Texture rate is 1,202.9 GTexel/s versus 384.0 GTexel/s. Memory bandwidth is 8.19 TB/s versus 432.0 GB/s. Memory capacity is 288 GB versus 24 GB. These figures indicate dominance in scientific simulation, AI training, large-scale data processing, and any workload that saturates memory or compute. The B300 also has tensor cores, enabling matrix operations that the LX PRO cannot accelerate. Its PCIe 6.0 x16 interface doubles the bandwidth of the LX PRO's PCIe 4.0 x16, reducing data transfer bottlenecks.

The Lisuan Tech LX PRO wins in rasterization-oriented metrics. Its pixel rate of 192.0 GPixel/s is nearly four times the B300's 48.77 GPixel/s. Its 96 ROPs compare favorably to the B300's 24. The LX PRO supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the B300 lists N/A for all APIs. The LX PRO includes display outputs, making it usable for direct video output. Its 225 W power draw is a fraction of the B300's 1100 W, and its dual-slot form factor fits standard chassis. The LX PRO's 24 GB GDDR6, while small by B300 standards, is sufficient for many workstation tasks, and its 2:1 FP16 ratio (49.15 TFLOPS) provides a boost for mixed-precision work.

In terms of production status, both are active. The B300's release date of September 2025 precedes the LX PRO's March 2026 date. The B300 has a successor listed (Server Rubin) and a predecessor (Server Hopper), while the LX PRO has neither. For users with access to server infrastructure and a need for extreme compute, the B300 is the data-backed choice. For users needing a self-contained GPU with display output and standard API support, the LX PRO is the functional option, though its performance remains unverified.
