AMD Radeon Instinct MI300 vs Lisuan Tech LX PRO Comparison

The AMD Radeon Instinct MI300 and Lisuan Tech LX PRO occupy very different positions in the hardware landscape. The MI300 is a data-center compute accelerator built for massive parallel workloads, while the LX PRO is a consumer-oriented graphics card with display outputs and gaming API support. Benchmark data shows both score at the 50th percentile among all GPUs, but their architectures and specifications point to entirely different intended use cases.

Where Each One Wins

The AMD Radeon Instinct MI300 is designed for compute-heavy environments where raw throughput matters more than visual output. Its 47.87 TFLOPS of FP32 performance more than doubles the 24.58 TFLOPS offered by the Lisuan Tech LX PRO. In FP16 workloads, the gap widens dramatically: the MI300 delivers 383.0 TFLOPS (8:1 ratio), while the LX PRO manages 49.15 TFLOPS (2:1 ratio). This represents a 7.8x advantage for the MI300 in half-precision compute, which is critical for AI training and inference tasks.

The Lisuan Tech LX PRO wins in areas related to traditional graphics rendering. It features 96 ROPs and a pixel rate of 192.0 GPixel/s, while the MI300 has 0 ROPs and a pixel rate of 0 MPixel/s. The LX PRO also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, whereas the MI300 lists no API support for these graphics standards. The LX PRO includes 4x DisplayPort 1.4a outputs, making it a functional graphics card for displays, while the MI300 has no display outputs at all.

The LX PRO also wins on memory efficiency relative to its power envelope. Its 432.0 GB/s of memory bandwidth comes from a 24 GB GDDR6 configuration on a 192-bit bus. The MI300 uses 128 GB of HBM3 on an 8192-bit bus, delivering 6.55 TB/s, which is 15.2x more bandwidth but with a much larger power draw.

Architecture Differences

The MI300 uses the Aqua Vanjaram chip based on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It contains 153,000 million transistors on a die size of 1017 mm², resulting in a transistor density of 150.4M per mm². The LX PRO uses the 7G105 chip based on TrueGPU architecture, manufactured on a 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown.

The MI300 has 14,080 shading units and 880 TMUs, while the LX PRO has 6,144 shading units and 192 TMUs. Texture rate favors the MI300 at 1,496.0 GTexel/s versus 384.0 GTexel/s for the LX PRO, a 3.9x difference. The MI300 has no ROPs, which is typical for compute accelerators that do not rasterize graphics, while the LX PRO has 96 ROPs for pixel output.

Clock behavior differs significantly. The MI300 runs at a base clock of 1000 MHz and boost clock of 1700 MHz, with memory at 1600 MHz (6.4 Gbps effective). The LX PRO does not list base or boost clocks, but its memory runs at 2250 MHz (18 Gbps effective). The bus interface also differs: PCIe 5.0 x16 for the MI300 versus PCIe 4.0 x16 for the LX PRO.

Head-to-Head Benchmarks

The FP16 comparison shows the largest performance gap. The MI300 achieves 383.0 TFLOPS at an 8:1 ratio, while the LX PRO achieves 49.15 TFLOPS at a 2:1 ratio. In raw numbers, the MI300 is 7.8x faster in half-precision compute. This matters for machine learning workloads that rely on FP16 arithmetic.

FP32 performance shows a 1.95x advantage for the MI300 at 47.87 TFLOPS versus 24.58 TFLOPS. Texture rate follows a similar pattern: the MI300 renders 1,496.0 GTexel/s compared to 384.0 GTexel/s for the LX PRO, a 3.9x difference. Memory bandwidth favors the MI300 by an even larger margin: 6.55 TB/s versus 432.0 GB/s, which is 15.2x more.

The LX PRO wins on pixel throughput. It delivers 192.0 GPixel/s thanks to its 96 ROPs, while the MI300 manages 0 MPixel/s. This confirms the LX PRO can rasterize graphics, while the MI300 cannot. The LX PRO also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, giving it a full graphics API stack. The MI300 lists null values for these APIs, showing it is not intended for interactive rendering.

Both cards sit at the 50th percentile among all GPUs, but this is a percentile rank across a broad database. The MI300 has no nearest rivals listed, and neither card has benchmark scores or head-to-head results recorded. The data available is purely from specifications, which paint a clear picture of divergent design goals.

The Verdict

The AMD Radeon Instinct MI300 is the choice for compute-heavy applications. Its 47.87 TFLOPS FP32, 383.0 TFLOPS FP16, and 6.55 TB/s memory bandwidth make it suited for data center workloads like AI training, scientific simulation, and large-scale matrix operations. Its 128 GB of HBM3 memory and 8192-bit bus allow it to handle datasets far larger than what the LX PRO can accommodate. The lack of display outputs and graphics API support means it is not a rendering card, and the 600 W TDP with a 1000 W suggested PSU indicates a server-grade installation.

The Lisuan Tech LX PRO is the choice for traditional graphics tasks. Its 96 ROPs, 192.0 GPixel/s pixel rate, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 make it a functional GPU for gaming and workstation rendering. The 4x DisplayPort 1.4a outputs allow direct monitor connection, and the 225 W TDP with a 550 W suggested PSU fits a standard desktop power supply. Its 24 GB of GDDR6 memory and 432.0 GB/s bandwidth are modest compared to the MI300, but sufficient for many rendering workloads. The dual-slot form factor and PCIe 4.0 x16 interface align with consumer motherboard compatibility.

The data indicates these are not competitors. They serve different markets: the MI300 for compute acceleration without visual output, the LX PRO for graphics rendering with full display support. A buyer needing FP16 throughput for AI models would use the MI300, while a user requiring DirectX 12 Ultimate and pixel output would select the LX PRO. The percentile scores are identical at 50, but the underlying specifications show no overlap in intended function.
