NVIDIA B200 SXM6 vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The recorded data splits these two accelerators into entirely separate use cases. The NVIDIA B200 SXM6 is a server-scale compute module built for massive memory bandwidth and high-precision throughput, while the Lisuan Tech LX MAX is a compact, self-contained graphics card with display outputs and consumer API support. Neither part wins across the board; each dominates in the domains its design targets.

The B200 SXM6 wins decisively in raw compute and memory capacity. It delivers 69.34 TFLOPS of FP32 throughput and the same 69.34 TFLOPS in FP16 with a 1:1 ratio, against the LX MAX's 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 at a 2:1 ratio. In FP32, the B200 is roughly 2.8 times faster. In FP16, the B200 still leads by about 41%. The B200 also carries 180 GB of HBM3e memory with 8.19 TB/s of bandwidth, versus 12 GB of GDDR6 at 432.0 GB/s on the LX MAX. That is a 15-fold memory capacity advantage and nearly 19 times the bandwidth.

The LX MAX wins in pixel throughput, physical integration, and interface compatibility. Its pixel rate of 192.0 GPixel/s is more than four times the B200's 43.92 GPixel/s. It has 96 ROPs against 24, and it outputs to four DisplayPort 1.4a connectors while the B200 has no display outputs. The LX MAX also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3; the B200 lists N/A for all three. The LX MAX uses a standard PCIe 4.0 x16 slot and a single 16-pin power connector, while the B200 is an SXM module with no display outputs and a 1400 W suggested PSU.

Architecture Differences

The two parts come from different foundries, nodes, and design philosophies. The B200 SXM6 uses NVIDIA's GB100 chip on a 5 nm process at TSMC, built on the Blackwell architecture and belonging to the Server Blackwell (Bxx) generation. It packs 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8 million per square millimeter. The LX MAX uses the 7G106 chip on a 6 nm process, also at TSMC, under the TrueGPU architecture and 7G100 generation. Its transistor count and die size are recorded as unknown.

Memory architecture differs fundamentally. The B200 uses HBM3e across an 8192-bit bus, running at 2000 MHz with 8 Gbps effective. The LX MAX uses GDDR6 across a 192-bit bus at 2250 MHz with 18 Gbps effective. The B200's memory clock is lower, but its bus width is over 42 times wider, which is why its bandwidth reaches 8.19 TB/s compared to 432.0 GB/s.

Compute resources also diverge sharply. The B200 has 18,944 shading units, 592 TMUs, and 592 tensor cores. The LX MAX has 6,144 shading units, 192 TMUs, and no tensor cores listed. The B200's texture rate is 1,083.4 GTexel/s versus 384.0 GTexel/s on the LX MAX. The B200's ROP count is far lower at 24, which explains its modest pixel rate. The LX MAX's 96 ROPs drive its high pixel output.

The B200 uses a PCIe 6.0 x16 interface, while the LX MAX uses PCIe 4.0 x16. The B200 is an SXM module with no power connector listed and a 1000 W TDP; the LX MAX is a dual-slot card with one 16-pin connector and a 225 W TDP. The B200 has no display outputs; the LX MAX has four DisplayPort 1.4a outputs. API support is absent on the B200 but present on the LX MAX.

Head-to-Head Benchmarks

The benchmark data shows no direct head-to-head results, but the specification sheet provides clear performance deltas. The largest win for the B200 SXM6 is in memory bandwidth: 8.19 TB/s versus 432.0 GB/s, a 19-fold advantage. That gap comes from the 8192-bit bus versus 192-bit, and the HBM3e versus GDDR6 memory type. For workloads that saturate memory, such as large model inference or data processing, the B200's advantage is overwhelming.

In FP32 compute, the B200 delivers 69.34 TFLOPS against 24.58 TFLOPS, a 2.8x lead. In FP16, the B200's 69.34 TFLOPS at 1:1 ratio beats the LX MAX's 49.15 TFLOPS at 2:1 ratio, a 41% lead. The B200 also has 592 tensor cores, while the LX MAX lists none, giving the B200 a structural advantage in matrix operations. Texture rate favors the B200 at 1,083.4 GTexel/s versus 384.0 GTexel/s, a 2.8x lead consistent with its FP32 ratio.

The LX MAX wins decisively in pixel throughput. Its 192.0 GPixel/s is 4.4 times the B200's 43.92 GPixel/s. This comes from 96 ROPs versus 24. For rasterization-heavy tasks or any workload that writes pixels, the LX MAX is substantially faster. The LX MAX also wins in memory clock speed at 2250 MHz versus 2000 MHz, though this does not offset the bandwidth gap.

Power efficiency favors the LX MAX. The B200 has a 1000 W TDP and requires a 1400 W suggested PSU. The LX MAX has a 225 W TDP and a 550 W suggested PSU. Per watt, the LX MAX delivers roughly 0.109 TFLOPS per watt in FP32 (24.58 / 225), while the B200 delivers about 0.069 TFLOPS per watt (69.34 / 1000). The LX MAX is about 58% more efficient in FP32 per watt. In FP16, the LX MAX delivers 0.218 TFLOPS per watt versus the B200's 0.069, a 3.2x efficiency advantage.

The B200 also leads in interface generation with PCIe 6.0 x16 versus PCIe 4.0 x16, and in transistor count at 208,000 million versus unknown. The LX MAX leads in API support, display outputs, and physical integration as a standard dual-slot card.

The Verdict

The data points to two mutually exclusive deployment profiles. The NVIDIA B200 SXM6 is for dense compute environments where memory capacity, memory bandwidth, and FP32/FP16 throughput are the primary constraints. Its 180 GB HBM3e pool, 8.19 TB/s bandwidth, and 69.34 TFLOPS FP32 make it suitable for large-scale server workloads that cannot fit in 12 GB of GDDR6. The 592 tensor cores and 1:1 FP16 ratio further position it for AI training and inference. The absence of display outputs and graphics APIs confirms it is not intended for any visual output role.

The Lisuan Tech LX MAX is for graphics-oriented tasks. Its 192.0 GPixel/s pixel rate, 96 ROPs, and four DisplayPort 1.4a outputs make it a capable display adapter. The DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support enable modern graphics APIs. Its 12 GB GDDR6 memory and 432.0 GB/s bandwidth are far below the B200 but sufficient for a card with a 225 W TDP and a 550 W suggested PSU. The dual-slot form factor and 1x 16-pin connector fit standard workstation or consumer configurations.

For FP32 compute density, the B200 is 2.8x faster. For pixel output, the LX MAX is 4.4x faster. For FP16 efficiency per watt, the LX MAX is 3.2x ahead. The B200 has no display outputs; the LX MAX has no tensor cores. The B200 uses PCIe 6.0; the LX MAX uses PCIe 4.0. The B200 launched on 2024-10-31 with a launch MSRP of 34,999 USD; the LX MAX launched on 2026-03-16 with no recorded MSRP.

The B200 SXM6 is the choice for server-side computation where memory footprint and bandwidth dominate. The LX MAX is the choice for any workload requiring rasterization, display output, or standard graphics API support. Selecting between them is not a matter of performance tier but of architectural purpose. The recorded data shows no overlap in their intended functions.
