AMD Instinct MI300X vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark result for the AMD Instinct MI300X, a Geekbench OpenCL score of 317,994. The Lisuan Tech LX PRO has no benchmark entries in the database, so a direct head-to-head comparison of measured scores is not possible. The MI300X's score places it at the 100th percentile of all GPUs in the database, confirming its position as a top-tier compute accelerator.

The MI300X's nearest rivals provide context for interpreting this score. The NVIDIA B200 leads with an average score of 345,482, which is 8% higher than the MI300X. The NVIDIA H200 NVL scores 334,891, a 5% advantage. Conversely, the MI300X outperforms the NVIDIA L40S by 7.5% (295,763) and the NVIDIA RTX 6000 Ada Generation by 10.7% (287,237). These deltas indicate the MI300X sits in a competitive band near the top, slightly behind the newest flagship accelerators but clearly ahead of the previous generation of professional workstation GPUs.

The LX PRO's absence of benchmark data means its performance cannot be quantified from the database. Its 50th percentile ranking is a default database state for unmeasured hardware, not a statement about real-world performance. The only available indication of its compute capability comes from its theoretical specifications, which differ significantly from the MI300X.

Architecture Differences

The MI300X and LX PRO represent fundamentally different architectural approaches. The MI300X uses AMD's CDNA 3.0 architecture, designed specifically for compute workloads. Its chip, codenamed Aqua Vanjaram, is built on a 5 nm process at TSMC and contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The LX PRO uses an architecture labeled TrueGPU, built on a 6 nm process, also at TSMC. Its transistor count and die size are unknown in the database.

The MI300X's compute pipeline is built around 19,456 shading units and 1,216 texture mapping units, with no ROPs recorded. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. The MI300X's texture rate is 2,553.6 GTexel/s, while the LX PRO achieves 384.0 GTexel/s. The MI300X reports 0 MPixel/s pixel throughput, while the LX PRO delivers 192.0 GPixel/s, a direct consequence of the MI300X lacking a traditional graphics rasterization pipeline.

Memory architecture further separates the two. The MI300X uses 192 GB of HBM3 across an 8192-bit bus, producing a bandwidth of 5.32 TB/s. The LX PRO uses 24 GB of GDDR6 across a 192-bit bus, producing 432.0 GB/s. The MI300X's memory clock is 1300 MHz (5.2 Gbps effective), while the LX PRO's memory clock is 2250 MHz (18 Gbps effective). Despite the LX PRO's higher memory clock speed, the MI300X's wider bus delivers over 12 times the bandwidth.

The MI300X's FP16 performance is listed as 81.72 TFLOPS (1:1 ratio with FP32), while the LX PRO's FP16 is 49.15 TFLOPS (2:1 ratio). This indicates the LX PRO has a separate, higher-throughput path for half-precision work, whereas the MI300X treats FP16 and FP32 symmetrically.

Where Each One Wins

The MI300X wins decisively in raw compute throughput. Its FP32 performance of 81.72 TFLOPS is 3.3 times higher than the LX PRO's 24.58 TFLOPS. Its texture rate of 2,553.6 GTexel/s is 6.7 times higher. Memory bandwidth of 5.32 TB/s dwarfs the LX PRO's 432.0 GB/s, and memory capacity of 192 GB is eight times larger. The MI300X's 19,456 shading units provide over three times the shading hardware of the LX PRO's 6,144 units.

The LX PRO wins in areas related to graphics output and physical integration. It provides 96 ROPs for pixel processing, delivering 192.0 GPixel/s, while the MI300X has no pixel throughput. The LX PRO supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, making it usable in interactive graphics environments. The MI300X lists no API support. The LX PRO includes 4 display outputs, enabling direct monitor connection, whereas the MI300X has no display outputs. The LX PRO's 225 W TDP is one-third of the MI300X's 750 W, and its 550 W suggested PSU is less than half of the MI300X's 1150 W requirement.

The LX PRO also offers higher memory clock speed at 18 Gbps effective versus 5.2 Gbps for the MI300X, though this does not translate into higher bandwidth due to the narrower bus. FP16 performance on the LX PRO is 49.15 TFLOPS, which is higher than its own FP32 rate, indicating a different compute strategy for half-precision workloads.

The Verdict

The data presents two accelerators with little overlap in intended use. The AMD Instinct MI300X is a compute-focused accelerator with a benchmark score of 317,994, placing it at the 100th percentile. Its nearest rivals show it is 5% behind the NVIDIA H200 NVL, 8% behind the NVIDIA B200, and 7.5% ahead of the NVIDIA L40S. This positions it as a high-end option for compute workloads where massive memory capacity and bandwidth are critical.

The Lisuan Tech LX PRO has no recorded benchmark scores, so its real-world performance cannot be verified from the database. Its specifications indicate a general-purpose graphics card: 24 GB of GDDR6, 4 display outputs, full DirectX 12 Ultimate support, and a dual-slot form factor. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 suggest it can handle graphics and compute tasks, but its 432.0 GB/s bandwidth and 192-bit bus limit its capacity for large data sets.

For users requiring maximum compute throughput, the MI300X is the clear choice based on the available data. Its 81.72 TFLOPS FP32, 5.32 TB/s bandwidth, and 192 GB memory capacity are recorded specifications that far exceed the LX PRO. The MI300X's 100th percentile ranking and competitive position against the B200 and H200 NVL confirm its high standing in the database.

For users needing a graphics card with display outputs, API support, and lower power draw, the LX PRO is the only option between the two. It provides 192.0 GPixel/s pixel throughput, DirectX 12 Ultimate support, and a 225 W TDP. Its 550 W suggested PSU requirement makes it suitable for systems where the MI300X's 1150 W requirement would be impractical.

The MI300X requires an OAM Module slot and has no power connectors, indicating it is designed for server platforms with dedicated power delivery. The LX PRO uses a standard PCIe 4.0 x16 interface and a 16-pin connector, fitting conventional desktop systems. The MI300X's release date of December 5, 2023, and the LX PRO's release date of March 16, 2026, show they come from different product cycles.

The absence of benchmark data for the LX PRO means its performance class cannot be established. Its percentile ranking of 50 is a placeholder, not a measured result. Users should consider the MI300X as the performance leader in this comparison, while the LX PRO's role is defined by its feature set rather than its measured speed.
