AMD Radeon Instinct MI300X vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data shows no overlapping benchmark results between the AMD Radeon Instinct MI300X and the Lisuan Tech LX PRO. The database contains no head-to-head benchmark entries, no win counts for either part, and no average benchmark scores for either GPU. Both products have an identical percentile ranking of 50 against all GPUs, and both show an average benchmark score of 0 in the database. This means a direct performance comparison cannot be established from measured results.

What can be compared are the theoretical compute ceilings derived from each product's specifications. The AMD Radeon Instinct MI300X delivers 81.72 TFLOPS of FP32 performance, while the Lisuan Tech LX PRO delivers 24.58 TFLOPS. The MI300X therefore holds a 3.3x advantage in FP32 throughput. In FP16 compute, the gap widens: the MI300X reaches 653.7 TFLOPS with an 8:1 ratio, versus 49.15 TFLOPS with a 2:1 ratio for the LX PRO. That is a 13.3x difference in peak FP16 output. The texture rate also favors the MI300X, which posts 2,553.6 GTexel/s against 384.0 GTexel/s for the LX PRO, a 6.65x margin. Pixel rate reverses the comparison: the MI300X records 0 MPixel/s, while the LX PRO records 192.0 GPixel/s. The MI300X has no ROPs (0), which explains the absence of a pixel fillrate; the LX PRO has 96 ROPs.

Memory bandwidth shows a substantial separation. The MI300X uses 192 GB of HBM3 across an 8192-bit bus, yielding 10.3 TB/s. The LX PRO uses 24 GB of GDDR6 across a 192-bit bus, yielding 432.0 GB/s. The MI300X provides 23.8x the bandwidth of the LX PRO. Memory capacity is also lopsided: 192 GB versus 24 GB, an 8x difference. Effective memory speed differs as well: 10.1 Gbps for the MI300X versus 18 Gbps for the LX PRO, though the MI300X's much wider bus dominates the bandwidth calculation.

Shading resources favor the MI300X. It has 19,456 shading units, 1,216 TMUs, and no ROPs. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. The MI300X carries 3.17x the shading units and 6.33x the TMUs. Neither product lists tensor cores or ray tracing cores in the database.

Clock behavior differs in completeness. The MI300X lists a base clock of 1000 MHz and a boost clock of 2100 MHz. The LX PRO lists no base or boost clock in the database. Memory clocks are recorded for both: 2525 MHz (10.1 Gbps effective) for the MI300X and 2250 MHz (18 Gbps effective) for the LX PRO.

The Verdict

The data supports different deployment targets for each GPU. The AMD Radeon Instinct MI300X is positioned for compute-heavy workloads that demand massive memory capacity and bandwidth. Its 192 GB HBM3 pool, 10.3 TB/s bandwidth, and 81.72 TFLOPS FP32 output place it in a class for large-scale data center compute. Its 750 W TDP and OAM Module form factor indicate a server-oriented installation.

The Lisuan Tech LX PRO targets workloads that require rendering output and display connectivity. It is the only one of the two with ROPs, a pixel rate, and display outputs (4x DisplayPort 1.4a). Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 are sufficient for graphics tasks within a 225 W envelope. The LX PRO also offers API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The MI300X lists no APIs and no display outputs.

The database shows both products at the 50th percentile among all GPUs, with no average benchmark scores and no nearest rivals recorded. That leaves specification-based analysis as the only comparative path. For raw compute density, memory bandwidth, and capacity, the MI300X dominates. For pixel processing, display output, and lower system power demands, the LX PRO is the relevant choice. The MI300X has no pixel rate and cannot drive displays. The LX PRO has no base or boost clock listed, so its dynamic performance range cannot be assessed from the database.

Architecture Differences

The MI300X is built on AMD's CDNA 3.0 architecture with the Aqua Vanjaram chip. The LX PRO uses the TrueGPU architecture with the 7G105 chip and belongs to the 7G100 generation. Both are fabricated by TSMC, but on different nodes: 5 nm for the MI300X and 6 nm for the LX PRO.

The MI300X belongs to the Radeon Instinct (MIx) generation. Its 153,000 million transistors are packed into a 1017 mm² die, giving a transistor density of 150.4M per mm². The LX PRO has no transistor count or die size in the database, so its density cannot be calculated.

Memory architecture diverges sharply. The MI300X uses HBM3 with a 192 GB capacity and an 8192-bit bus, which is consistent with a data center accelerator design. The LX PRO uses GDDR6 with 24 GB capacity and a 192-bit bus, consistent with a conventional graphics board.

Feature support differs at the API level. The LX PRO exposes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The MI300X records no API support, aligning with a compute-only accelerator that has no display path. The LX PRO also includes 4x DisplayPort 1.4a outputs, while the MI300X has no outputs at all.

Rasterization resources separate the two designs. The MI300X has 0 ROPs and a 0 MPixel/s pixel rate, indicating it is not designed for pixel output. The LX PRO has 96 ROPs and a 192.0 GPixel/s pixel rate, indicating full rasterization capability. Texture throughput also differs: the MI300X reaches 2,553.6 GTexel/s, while the LX PRO reaches 384.0 GTexel/s.

Power delivery architecture reflects the different intended environments. The MI300X is an OAM Module with no power connectors and a 750 W TDP. The LX PRO is a dual-slot card with one 16-pin connector and a 225 W TDP. The suggested PSU values follow the same split: 1150 W for the MI300X and 550 W for the LX PRO.

The MI300X uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The MI300X released on 2023-12-05 and has a predecessor named FirePro Data Center. The LX PRO is dated 2026-03-16 with no predecessor listed. The LX PRO is marked as active in production; the MI300X has no production status recorded.
