AMD Instinct MI350X vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database shows no recorded benchmark scores for either the AMD Instinct MI350X or the Lisuan Tech LX PRO. Both cards return an average benchmark score of 0 and a percentile ranking of 50 against all GPUs. With no head-to-head benchmark entries, wins and losses cannot be assigned. The MI350X does not appear in any benchmark lists, and the LX PRO likewise has no recorded performance data. This means the comparison must rely entirely on architectural and specification analysis rather than measured results.

The AMD Instinct MI350X delivers 72.09 TFLOPS of FP32 compute and 72.09 TFLOPS of FP16 with a 1:1 ratio. The Lisuan Tech LX PRO produces 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 with a 2:1 ratio. In raw floating-point throughput, the MI350X leads by a factor of approximately 2.93 in FP32 and 1.47 in FP16. These figures come directly from the specification sheets in the database.

Texture throughput follows the same pattern. The MI350X reaches 2,252.8 GTexel/s, while the LX PRO manages 384.0 GTexel/s. That places the AMD part roughly 5.87 times higher in texture fill rate. Pixel rate tells a different story. The MI350X lists 0 MPixel/s because the card has no ROPs. The LX PRO has 96 ROPs and a pixel rate of 192.0 GPixel/s. For any workload requiring rasterization or direct pixel output, the LX PRO is the only one of the two that can operate at all in this category.

Memory capacity and bandwidth heavily favor the MI350X. It carries 288 GB of HBM3e on an 8192-bit bus, producing 8.19 TB/s of bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The MI350X bandwidth advantage is roughly 18.96 times greater. Memory clock rates differ as well: the MI350X memory runs at 2000 MHz with 8 Gbps effective speed, while the LX PRO memory runs at 2250 MHz with 18 Gbps effective speed. The faster per-pin speed of the LX PRO does not compensate for the vastly wider bus on the MI350X.

Shader resources follow the compute lead. The MI350X has 16,384 shading units and 1,024 TMUs. The LX PRO has 6,144 shading units and 192 TMUs. The MI350X has 2.67 times the shading units and 5.33 times the TMUs. Neither card lists tensor cores or ray tracing cores in the database.

Clock speeds are only partially documented. The MI350X has a base clock of 1000 MHz and a boost clock of 2200 MHz. The LX PRO has no base or boost clock listed. Without clock data for the LX PRO, direct clock-to-clock comparisons are impossible. The MI350X operates at higher absolute frequencies per the recorded figures.

Power and cooling requirements diverge sharply. The MI350X has a TDP of 1000 W and a suggested PSU of 1400 W. It uses an OAM Module slot width and has no power connectors listed. The LX PRO has a TDP of 225 W, a suggested PSU of 550 W, a dual-slot form factor, and a single 16-pin power connector. The MI350X demands roughly 4.44 times the power budget of the LX PRO.

Physical dimensions also differ. The MI350X measures 102 mm in length and 165 mm in width. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width. The LX PRO is longer and taller but much narrower. The MI350X is a compact module designed for server chassis, while the LX PRO fits conventional expansion slots.

The bus interfaces are not identical. The MI350X uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. This gives the MI350X double the per-lane bandwidth of the LX PRO, though actual throughput depends on workload and system support. Display outputs also separate the two: the MI350X has no outputs, while the LX PRO provides four DisplayPort 1.4a connections.

API support differs completely. The MI350X lists N/A for DirectX, OpenGL, and Vulkan. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The MI350X is not a graphics card in the traditional sense, while the LX PRO carries full graphics API compatibility.

The Verdict

The data indicates two devices built for entirely different purposes. The AMD Instinct MI350X is a compute accelerator with massive memory, high FP32 and FP16 throughput, and no display or graphics API support. The Lisuan Tech LX PRO is a conventional graphics card with rasterization capability, display outputs, and consumer API support.

For compute-heavy workloads such as large-scale AI training, scientific simulation, or high-bandwidth data processing, the MI350X has the clear advantage. Its 288 GB memory capacity, 8.19 TB/s bandwidth, and 72.09 TFLOPS FP32 make it suitable for problems that exceed the memory capacity of the LX PRO by an order of magnitude. The LX PRO cannot hold datasets that the MI350X handles as routine.

For traditional graphics tasks, gaming, or any workload requiring DirectX, OpenGL, or Vulkan, the LX PRO is the only viable option. The MI350X has no display outputs and no graphics API support. It cannot render frames to a screen. The LX PRO has 96 ROPs, a 192.0 GPixel/s pixel rate, and four DisplayPort 1.4a outputs.

The power envelope reinforces this split. The MI350X needs 1000 W and a 1400 W PSU, typical for a rack-mounted accelerator. The LX PRO needs 225 W and a 550 W PSU, fitting standard workstation or desktop builds. The LX PRO's 16-pin connector is a conventional interface, while the MI350X uses no discrete connectors because it receives power through the OAM module slot.

Release timing also matters. The MI350X was released on 2025-06-11. The LX PRO has a release date of 2026-03-16. The LX PRO is the newer product, and its production status is listed as Active, while the MI350X has no production status recorded.

Neither card has an average benchmark score above zero, so no performance ranking can be derived from measured results. The percentile rank of 50 for both is identical and reflects the absence of data rather than actual performance parity.

Where Each One Wins

The AMD Instinct MI350X wins in every category related to raw compute throughput and memory capacity. FP32 performance stands at 72.09 TFLOPS versus 24.58 TFLOPS.

The MI350X also uses a newer process node at 3 nm versus 6 nm, both fabricated by TSMC.

The Lisuan Tech LX PRO wins in categories related to graphics output and rasterization. It has 96 ROPs and a pixel rate of 192.0 GPixel/s, while the MI350X has 0 ROPs and 0 MPixel/s. It provides four DisplayPort 1.4a outputs, while the MI350X has none. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the MI350X supports none of these APIs. The LX PRO also has a higher memory clock at 2250 MHz with 18 Gbps effective speed, compared to 2000 MHz with 8 Gbps effective on the MI350X. The LX PRO has a lower TDP at 225 W versus 1000 W, and a lower suggested PSU at 550 W versus 1400 W.

The LX PRO is the only one with a complete set of dimensions. It measures 248 mm by 118 mm by 48 mm. The MI350X measures 102 mm by 165 mm with no height recorded. The LX PRO uses a dual-slot design with a standard 16-pin power connector, while the MI350X uses an OAM Module with no power connectors. The LX PRO uses PCIe 4.0 x16, while the MI350X uses PCIe 5.0 x16. The LX PRO has a DirectX 12 Ultimate feature level, which the MI350X completely lacks.

For use cases involving machine learning inference or training on very large models, the MI350X is the stronger choice. For use cases involving real-time 3D rendering, video output, or any consumer software stack, the LX PRO is the only choice. The MI350X has 185,000 million transistors on a 2380 mm² die, while the LX PRO has unknown transistor count and die size. The MI350X transistor density is 77.7M per mm².
