NVIDIA B300 vs Lisuan Tech LX 7G100 Comparison

Where Each One Wins

The recorded benchmark data for the NVIDIA B300 and the Lisuan Tech LX 7G100 shows no completed benchmark runs for either part. The database lists zero wins for both the B300 and the LX 7G100 in head-to-head comparisons, and the average benchmark scores are zero for both. This means the current dataset does not provide any direct performance measurements to separate these two accelerators on the basis of tested workloads.

Without benchmark scores, the use-case split must be derived from the architectural and specification differences recorded in the database. The NVIDIA B300 is a 1400 W SXM module with 144 GB of HBM3e memory and a 4096-bit memory bus. The Lisuan Tech LX 7G100 is a 225 W dual-slot card with 12 GB of GDDR6 memory and a 192-bit bus. These are fundamentally different classes of hardware. The B300 targets the highest tier of server compute, where memory capacity and bandwidth dominate. The LX 7G100 targets a more conventional workstation or edge server role, with a standard PCIe 4.0 x16 interface and display outputs.

The B300 shows a massive lead in raw shader throughput: 76.99 TFLOPS FP32 versus 24.58 TFLOPS for the LX 7G100. The B300 also has more than double the shading units (18944 versus 6144), more TMUs (592 versus 192), and far fewer ROPs (24 versus 96). The LX 7G100 counters with a pixel rate of 192.0 GPixel/s versus 48.77 GPixel/s for the B300, indicating the Lisuan part is designed for rasterization-heavy output, while the B300 is optimized for compute and AI workloads that do not rely on pixel fill.

The B300 uses the Blackwell Ultra architecture with a GB110 chip built on a 5 nm process at TSMC, containing 104,000 million transistors. The LX 7G100 uses the TrueGPU architecture with a 7G106 chip on a 6 nm process at TSMC, with transistor count listed as unknown. The B300 includes 592 tensor cores, while the LX 7G100 has none listed. The B300 also delivers 1,231.8 TFLOPS FP16 (16:1 ratio), versus 49.15 TFLOPS FP16 (2:1 ratio) for the LX 7G100. This is a 25x difference in FP16 throughput, confirming the B300 is built for tensor-heavy workloads such as large language model training and inference.

Architecture Differences

The two accelerators come from different design philosophies. The NVIDIA B300 is part of the Server Blackwell generation, using the GB110 chip and the Blackwell Ultra architecture. The Lisuan Tech LX 7G100 is from the 7G100 generation, using the 7G106 chip and the TrueGPU architecture. Both are fabricated by TSMC, but on different nodes: the B300 uses 5 nm, while the LX 7G100 uses 6 nm.

Transistor count is a major differentiator. The B300 packs 104,000 million transistors. The LX 7G100 has an unknown transistor count, but given its 6 nm process and 6144 shading units, the die is far smaller in capability. The B300 has 18944 shading units, 592 TMUs, and 24 ROPs. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. The ROP disparity is notable: the LX 7G100 has four times the pixel throughput capability per clock, which aligns with its 192.0 GPixel/s pixel rate versus 48.77 GPixel/s for the B300.

Memory architecture is the starkest difference. The B300 uses 144 GB of HBM3e with a 4096-bit bus and 4.10 TB/s bandwidth. The LX 7G100 uses 12 GB of GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The B300 has 12 times the memory capacity and roughly 9.5 times the bandwidth. The B300 also runs its memory at 2000 MHz with 8 Gbps effective, while the LX 7G100 runs at 2250 MHz with 18 Gbps effective. The GDDR6 clock is higher, but the narrow bus limits total throughput.

Tensor capabilities separate the two. The B300 has 592 tensor cores and delivers 1,231.8 TFLOPS FP16 at a 16:1 ratio. The LX 7G100 has no tensor cores listed and delivers 49.15 TFLOPS FP16 at a 2:1 ratio. The FP16 ratio difference indicates the B300 is heavily skewed toward mixed-precision AI math, while the LX 7G100 treats FP16 as a straightforward half-precision mode.

Power and physical design also diverge. The B300 is an SXM module with a 1400 W TDP and a suggested PSU of 1800 W. The LX 7G100 is a dual-slot card with a 225 W TDP, a single 8-pin power connector, and a suggested PSU of 550 W. The B300 has no display outputs; the LX 7G100 has four DisplayPort 1.4a outputs. The B300 uses PCIe 5.0 x16, the LX 7G100 uses PCIe 4.0 x16. The LX 7G100 also carries API support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the B300 has no API entries in the database.

The Verdict

The data supports a clear split. The NVIDIA B300 is for compute-dense server environments where memory bandwidth, FP16 throughput, and tensor core capacity are the primary requirements. With 144 GB of HBM3e at 4.10 TB/s and 1,231.8 TFLOPS FP16, it is built for large-scale AI workloads. The absence of display outputs and the SXM form factor confirm it is not intended for interactive graphics.

The Lisuan Tech LX 7G100 is for conventional GPU workloads that require display output, rasterization, and standard API support. Its 192.0 GPixel/s pixel rate, 96 ROPs, and four DisplayPort 1.4a outputs place it in workstation or edge inference territory. The 12 GB of GDDR6 at 432.0 GB/s is modest but appropriate for a 225 W card. The 24.58 TFLOPS FP32 is roughly one third of the B300's 76.99 TFLOPS, but the LX 7G100 does not need to match the B300 in raw compute; it serves a different segment.

The B300 leads in every compute metric recorded: shading units, TMUs, FP32, FP16, memory capacity, memory bandwidth, and transistor count. The LX 7G100 leads in pixel rate, ROPs, and display connectivity. There is no overlap in target use cases. The B300 is a server accelerator; the LX 7G100 is a graphics-capable compute card.

Head-to-Head Benchmarks

The database contains no completed head-to-head benchmark runs for these two parts. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. As a result, there are no measured scores to compare directly. The analysis must rely on the specification-level data recorded for each accelerator.

The largest compute gap is in FP16 throughput. The B300 shows 1,231.8 TFLOPS FP16 (16:1), versus 49.15 TFLOPS FP16 (2:1) for the LX 7G100. This is a 25-fold difference and indicates the B300 is designed for workloads that can exploit the 16:1 ratio, such as transformer models with reduced precision. The LX 7G100's 2:1 ratio means its FP16 performance is exactly half its FP32 performance, a conventional arrangement.

In FP32, the B300 leads by 52.41 TFLOPS (76.99 versus 24.58). The B300 also leads in texture rate at 1,202.9 GTexel/s versus 384.0 GTexel/s for the LX 7G100. The pixel rate reverses the order: the LX 7G100 achieves 192.0 GPixel/s, while the B300 achieves 48.77 GPixel/s. This is a 3.9x advantage for the Lisuan part and reflects the ROP count difference (96 versus 24).

Memory bandwidth favors the B300 at 4.10 TB/s versus 432.0 GB/s for the LX 7G100. The B300's 4096-bit bus is 21.3 times wider than the LX 7G100's 192-bit bus. The memory clocks differ, with the LX 7G100 running at 2250 MHz (18 Gbps effective) versus 2000 MHz (8 Gbps effective) for the B300, but the bus width difference dominates the bandwidth calculation.

The transistor count is another major gap. The B300 contains 104,000 million transistors. The LX 7G100's transistor count is unknown, but the 6144 shading units on a 6 nm process suggests a much smaller implementation. The process node difference (5 nm versus 6 nm) also contributes to the B300's higher density.

The B300 has no API entries for DirectX, OpenGL, or Vulkan. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. This means the LX 7G100 can run modern graphics APIs, while the B300 is not recorded as supporting any graphics API, consistent with its compute-only server role.
