AMD Instinct MI308X vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either the AMD Instinct MI308X or the Lisuan Tech LX PRO. The head-to-head comparisons field is empty, and both products show an average benchmark score of zero. As a result, no direct performance deltas can be calculated between the two accelerators.

The AMD Instinct MI308X is listed with an FP32 throughput of 81.72 TFLOPS and an FP16 throughput of 81.72 TFLOPS at a 1:1 ratio. The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 and 49.15 TFLOPS of FP16 at a 2:1 ratio. These figures indicate the AMD part has 3.3 times the raw FP32 throughput of the LX PRO, and 1.66 times the FP16 throughput. Texture fill rates differ substantially: the MI308X reaches 2,553.6 GTexel/s versus 384.0 GTexel/s for the LX PRO, a factor of 6.65. Pixel fill rates tell the opposite story in terms of architecture design: the MI308X reports 0 MPixel/s while the LX PRO produces 192.0 GPixel/s.

The nearest rivals fields for both entries are empty, and the percentile versus all GPUs is recorded at 50 for each. Without actual benchmark runs, the percentile values represent a neutral midpoint rather than measured performance. The data confirms that any comparison between these two products must rely on specification sheets and architectural characteristics, not on empirical test results.

Where Each One Wins

Based on the recorded specifications, the AMD Instinct MI308X leads in raw compute density, memory capacity, memory bandwidth, and texture throughput. Its 81.72 TFLOPS FP32 output positions it clearly ahead of the LX PRO's 24.58 TFLOPS for workloads that scale with single-precision arithmetic. The 192 GB HBM3 memory array with an 8192 bit bus and 5.32 TB/s bandwidth gives the MI308X a decisive advantage in datasets that exceed the LX PRO's 24 GB GDDR6 frame buffer. The LX PRO's 432.0 GB/s bandwidth is only 8.1 percent of the MI308X's bandwidth, which limits its applicability for large matrix operations or high-volume data streaming.

The Lisuan Tech LX PRO wins in areas related to display output and graphics processing. It includes 4x DisplayPort 1.4a outputs, while the MI308X has no display outputs. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3; the MI308X reports N/A for all three APIs. The LX PRO has 96 ROPs delivering 192.0 GPixel/s, whereas the MI308X reports zero ROPs and zero pixel rate. For rendering pipelines that require rasterization, the LX PRO is the only one of the two with functional graphics capability. The LX PRO also uses a dual-slot form factor with a single 16-pin power connector, whereas the MI308X is an OAM module with no power connectors, meaning the LX PRO can be installed in a conventional PCIe slot while the MI308X requires an OAM carrier.

Architecture Differences

The AMD Instinct MI308X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip, fabricated on a 6 nm process, also at TSMC. The process node difference is one generation step: 5 nm versus 6 nm, which gives the MI308X a density advantage in principle.

The MI308X contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The LX PRO's transistor count and die size are listed as unknown, so no density comparison is possible. The MI308X 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 ratio of shading units is 3.17 to 1 in favor of AMD, and the TMU ratio is 6.33 to 1. The LX PRO's inclusion of ROPs and the MI308X's complete lack of them reflects their divergent design goals: one is a compute accelerator, the other is a graphics-capable processor.

Memory architectures are fundamentally different. The MI308X uses HBM3 with 192 GB capacity, an 8192 bit bus, and 5.32 TB/s bandwidth. The LX PRO uses GDDR6 with 24 GB capacity, a 192 bit bus, and 432.0 GB/s bandwidth. The MI308X's memory clock is listed as 1300 MHz with 5.2 Gbps effective, while the LX PRO's memory clock is 2250 MHz with 18 Gbps effective. The LX PRO's memory runs at a higher clock frequency, but the MI308X's 42.7 times wider bus delivers far greater aggregate bandwidth.

The MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz. The LX PRO has no base or boost clock recorded. FP16 support differs in ratio: the MI308X provides 81.72 TFLOPS at 1:1 with FP32, while the LX PRO provides 49.15 TFLOPS at 2:1, meaning the LX PRO's FP16 rate is double its FP32 rate. This indicates the LX PRO has dedicated or accelerated half-precision paths that the MI308X does not emphasize, despite the MI308X's higher absolute FP16 number.

The MI308X has no RT cores and no tensor cores listed; the LX PRO also lists no RT cores and no tensor cores. Neither part carries dedicated ray tracing hardware in the database. The MI308X uses a PCIe 5.0 x16 bus interface, while the LX PRO uses PCIe 4.0 x16. The MI308X is an OAM module, the LX PRO is a dual-slot card measuring 248 mm in length, 118 mm in height, and 48 mm in width.

Specification Differences

The power profiles differ sharply. The MI308X has a TDP of 750 W and a suggested PSU of 1150 W. The LX PRO has a TDP of 225 W and a suggested PSU of 550 W. The MI308X requires 3.33 times the power of the LX PRO. The MI308X uses no power connectors because it is an OAM module; the LX PRO uses a single 16-pin connector.

The release dates are far apart. The MI308X was released on 2023-12-05, and the LX PRO on 2026-03-16. The production status for the MI308X is not recorded, while the LX PRO is listed as Active. The MI308X has a predecessor named Radeon Instinct; the LX PRO has no predecessor listed. Neither has a recorded successor or launch MSRP.

The interface generation differs: PCIe 5.0 x16 for the MI308X versus PCIe 4.0 x16 for the LX PRO. The MI308X has no display outputs; the LX PRO has 4x DisplayPort 1.4a. The MI308X's API support is N/A across DirectX, OpenGL, and Vulkan; the LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The LX PRO's dimensions are fully recorded, while the MI308X's length, height, and width are null.

The memory capacities differ by a factor of 8: 192 GB versus 24 GB. The bus widths differ by a factor of 42.7: 8192 bit versus 192 bit. The MI308X's shading unit count is 3.17 times higher, TMU count is 6.33 times higher, and ROP count is 96 lower. The LX PRO has a pixel rate of 192.0 GPixel/s, while the MI308X has 0 MPixel/s. The MI308X's texture rate of 2,553.6 GTexel/s is 6.65 times the LX PRO's 384.0 GTexel/s.

The Verdict

The AMD Instinct MI308X is positioned as a high-density compute accelerator. Its 192 GB HBM3 memory, 5.32 TB/s bandwidth, and 81.72 TFLOPS FP32 place it in a class for large-scale numerical workloads. The lack of display outputs, rasterization hardware, and graphics APIs confirms that it is not intended for interactive rendering. The 750 W TDP and OAM form factor require specialized infrastructure. The data indicates this part is designed for server-side compute tasks where memory capacity and bandwidth dominate.

The Lisuan Tech LX PRO is a dual-slot graphics card with 24 GB GDDR6 memory, 96 ROPs, and a 192.0 GPixel/s pixel rate. It supports modern graphics APIs, includes four DisplayPort outputs, and runs at 225 W TDP with a 550 W suggested PSU. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 make it a general-purpose GPU that can handle both rendering and compute workloads, but at a fraction of the MI308X's peak arithmetic throughput.

The database shows no benchmark scores for either product, so the verdict rests on specifications. For applications that require massive memory capacity, extreme memory bandwidth, and maximum FP32 throughput, the AMD Instinct MI308X is the only option between the two that meets those requirements. For systems that need graphics output, standard PCIe installation, rasterization, and lower power draw, the Lisuan Tech LX PRO is the suitable choice.

The MI308X's 6.65 times higher texture rate and 3.3 times higher FP32 come with a 3.33 times higher TDP. The LX PRO trades compute density for versatility: it is the only one with pixel output, API support, and a conventional power connector. The 5 nm process of the MI308X versus the 6 nm process of the LX PRO gives the AMD part a manufacturing advantage, though the LX PRO retains a full set of display and graphics features that the MI308X lacks entirely.
