NVIDIA B300 SXM6 AC vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The NVIDIA B300 SXM6 AC is a server-grade compute accelerator built for maximum throughput in AI, scientific computing, and data center workloads. Its recorded OpenCL benchmark score of 369,831 places it at the 100th percentile of all GPUs in the database, meaning it outperforms every other recorded graphics processor. The nearest rival, NVIDIA B200, scores 345,482, which is 7% lower, while the H200 NVL trails by 10.4% at 334,891. AMD's Instinct MI300X sits 16.3% behind at 317,994, and the L40S is 25% lower at 295,763. For any task where raw compute throughput matters, the B300 SXM6 AC holds a decisive advantage.

The Lisuan Tech LX MAX, by contrast, is a conventional dual-slot graphics card with display outputs, a 225 W power draw, and a 50th percentile ranking. It has no recorded benchmark scores in the database, so its performance profile must be inferred from its specifications. It targets standard desktop and workstation scenarios: rendering, gaming, and general-purpose GPU compute within a 550 W PSU budget. The LX MAX wins in practical accessibility: it fits in a standard tower, uses a PCIe 4.0 x16 slot, and provides four DisplayPort 1.4a outputs for direct monitor connection. The B300 SXM6 AC has no display outputs and requires a server chassis with SXM module support.

The use-case split is clear. The B300 SXM6 AC is for environments where compute density and memory bandwidth dominate, such as large language model training, scientific simulation, or batch inference. The LX MAX is for individual workstations needing a capable GPU with flexible connectivity. Neither card competes in the other's primary arena.

Architecture Differences

The B300 SXM6 AC uses the GB110 chip built on NVIDIA's Blackwell Ultra architecture, fabricated on a 5 nm process at TSMC. The die measures 1628 mm² and packs 208,000 million transistors, yielding a transistor density of 127.8 million per square millimeter. This is a massive, power-hungry chip designed for maximum parallel throughput. It employs HBM3e memory totaling 288 GB across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The compute layout includes 18,944 shading units, 592 texture mapping units, and 592 tensor cores, with a pixel rate of 48.77 GPixel/s and a texture rate of 1,202.9 GTexel/s. FP32 performance is 76.99 TFLOPS, and FP16 matches at 76.99 TFLOPS with a 1:1 ratio. The card draws 1100 W and requires a 1500 W PSU, using a PCIe 6.0 x16 interface. It has no display outputs and no DirectX, OpenGL, or Vulkan support, confirming its server-only orientation.

The Lisuan Tech LX MAX uses the 7G106 chip on a 6 nm process, also at TSMC. Transistor count and die size are unknown. It pairs 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s of bandwidth, which is far lower than the B300's HBM3e. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs, with no tensor cores listed. Its pixel rate is 192.0 GPixel/s and texture rate is 384.0 GTexel/s. FP32 computes 24.58 TFLOPS, while FP16 reaches 49.15 TFLOPS with a 2:1 ratio, indicating a consumer-oriented design where FP16 throughput is doubled rather than matched. The card draws 225 W, needs a 550 W PSU, uses a single 16-pin power connector, and fits in a dual-slot 248 mm length, 118 mm height, and 48 mm width. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, and includes four DisplayPort 1.4a outputs.

Architecturally, the B300 SXM6 AC is a compute monster with tensor cores and massive HBM capacity. The LX MAX is a rasterization-focused GPU with modern API support and display outputs. The 5 nm versus 6 nm process difference is small, but the die size, memory type, and feature set diverge sharply.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the B300 SXM6 AC and the LX MAX. The B300 SXM6 AC has a single Geekbench OpenCL score of 369,831, which is 100% of all GPUs. The LX MAX has no benchmark entries and an average score of 0, placing it at the 50th percentile by default ranking rather than by measured performance.

Comparisons must rely on the nearest rivals of the B300 SXM6 AC. Against the NVIDIA B200, the B300 scores 7% higher. Against the H200 NVL, the advantage is 10.4%. The AMD Instinct MI300X is 16.3% behind, and the L40S trails by 25%. These deltas show a consistent performance ladder where the B300 SXM6 AC sits at the top.

For the LX MAX, no rival data exists. Its FP32 throughput of 24.58 TFLOPS and memory bandwidth of 432.0 GB/s are modest figures compared to the B300's 76.99 TFLOPS and 8.19 TB/s, but those numbers come from the specification sheet, not from recorded benchmarks. The LX MAX's pixel rate of 192.0 GPixel/s is higher than the B300's 48.77 GPixel/s, which suggests a rasterization-oriented design where pixel output matters more than compute density. The LX MAX also doubles FP16 performance relative to FP32, a trait common in consumer GPUs.

Without head-to-head data, the performance gap is inferable only from specifications. The B300 SXM6 AC has 3.1 times the FP32 throughput of the LX MAX and roughly 19 times the memory bandwidth. The LX MAX has 4 times the pixel rate, which aligns with its display-oriented role.

The Verdict

The data points to two entirely different products for different buyers. The NVIDIA B300 SXM6 AC is a top-tier server accelerator with the highest recorded benchmark score in the database, 369,831, sitting at the 100th percentile. It leads the nearest rival, the B200, by 7%, and the H200 NVL by 10.4%. Its 288 GB HBM3e memory and 8.19 TB/s bandwidth make it suitable for memory-bound AI and scientific workloads. The 1100 W power draw and SXM module form factor restrict it to enterprise racks with appropriate cooling and power delivery.

The Lisuan Tech LX MAX is a mainstream dual-slot graphics card with 12 GB GDDR6, 225 W power draw, and four DisplayPort outputs. It has no recorded benchmarks, but its specifications show a rasterization-first design: 192 ROPs, 192.0 GPixel/s pixel rate, and 49.15 TFLOPS FP16 with a 2:1 ratio. It supports modern graphics APIs and fits in standard PC cases with a 550 W PSU.

The choice depends strictly on the workload. For dense compute, massive memory pools, and server deployment, the B300 SXM6 AC is the only option. For desktop graphics, direct display output, and moderate power consumption, the LX MAX is the practical pick. The B300 SXM6 AC wins on raw performance and memory capacity. The LX MAX wins on accessibility, connectivity, and efficiency. Neither substitutes for the other.
