AMD Instinct MI300 vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Instinct MI300 and the Lisuan Tech LX MAX. Both entries show an average benchmark score of 0 and an empty benchmark list, so no frame rates, compute scores, or synthetic test results are available to compare. The percentileVsAllGpus field places both at the 50th percentile, which indicates that neither part has a measured performance profile in the database that would shift it above or below the midpoint of all recorded GPUs. Without benchmark samples, the FP32 and FP16 throughput figures from the specification sheets serve as the only quantitative performance indicators.

The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 compute and 47.87 TFLOPS of FP16 compute with a 1:1 ratio. The Lisuan Tech LX MAX delivers 24.58 TFLOPS of FP32 and 49.15 TFLOPS of FP16 with a 2:1 ratio. In raw FP32 throughput, the MI300 leads by a factor of roughly 1.95, meaning it is about 95% higher than the LX MAX. In FP16 throughput, the LX MAX actually leads slightly, with 49.15 TFLOPS versus 47.87 TFLOPS, a margin of about 2.7%. These figures represent theoretical peak rates from the database, not measured application results.

Texture and pixel rates also differ sharply. The MI300 posts a texture rate of 1,496.0 GTexel/s, while the LX MAX posts 384.0 GTexel/s. That puts the MI300 at roughly 3.9 times the texture throughput of the LX MAX. The pixel rate tells a different story: the MI300 shows 0 MPixel/s because its ROP count is listed as 0, while the LX MAX shows 192.0 GPixel/s. The MI300 is positioned as a compute accelerator with no display output path, so its pixel rate is effectively nonexistent in the database, whereas the LX MAX has a conventional rasterization pipeline with 96 ROPs.

Memory bandwidth is another major separator. The MI300 uses 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The MI300 has roughly 12.3 times the memory bandwidth of the LX MAX. That difference dominates any workload that is memory-bound, including large model inference, scientific simulation, and high-resolution data processing. The LX MAX memory clock is listed at 2250 MHz with 18 Gbps effective, while the MI300 memory clock is listed at 1300 MHz with 5.2 Gbps effective, but the bus width difference reverses the effective bandwidth outcome completely.

Where Each One Wins

The AMD Instinct MI300 wins in scenarios that demand massive memory capacity and bandwidth. Its 128 GB HBM3 pool and 5.32 TB/s bandwidth place it in a category for large-scale compute workloads, such as training or inference on large neural networks, where the working set exceeds the 12 GB capacity of the LX MAX. The 8192-bit memory bus is the widest in the database for these two parts, and the 5 nm process node with 153,000 million transistors on a 1017 mm² die indicates a chip built for throughput density. The FP32 rate of 47.87 TFLOPS gives it a clear advantage in single-precision compute tasks that do not rely on tensor or ray tracing hardware, since neither part lists tensor cores or RT cores.

The Lisuan Tech LX MAX wins in FP16 peak throughput, posting 49.15 TFLOPS, which is 1.28 TFLOPS higher than the MI300. That makes it the better choice for workloads that run in half precision and can use its 2:1 FP16 ratio, such as certain machine learning inference paths or graphics shader work that leverages FP16 math. The LX MAX also wins in display and rasterization capability. It has 4x DisplayPort 1.4a outputs, a DirectX 12 Ultimate (12_2) API rating, OpenGL 4.6, and Vulkan 1.3 support. The MI300 has no display outputs and its API fields are listed as N/A. For any workload requiring a video output, a rendering pipeline, or graphics API compatibility, the LX MAX is the only viable option of the two.

The LX MAX also wins on power draw. Its TDP is 225 W with a suggested PSU of 550 W, compared to the MI300 at 600 W with a suggested PSU of 1000 W. The LX MAX uses a single 16-pin power connector and fits in a dual-slot form factor, while the MI300 uses two 8-pin connectors. The LX MAX is also physically shorter at 248 mm (9.8 inches) versus 267 mm (10.5 inches) for the MI300, and it is slightly taller at 118 mm (4.6 inches) versus 111 mm (4.4 inches). The LX MAX has a listed width of 48 mm (1.9 inches), while the MI300 has no width listed.

Architecture Differences

The MI300 uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC. It belongs to the Instinct (MIx) generation. The LX MAX uses the TrueGPU architecture on the 7G106 chip, built on a 6 nm process, also at TSMC, and belongs to the 7G100 generation. The process node difference is small, 5 nm versus 6 nm, but the transistor counts are not comparable in the database: the MI300 lists 153,000 million transistors on a 1017 mm² die, while the LX MAX lists transistor count and die size as unknown.

Shading unit counts differ substantially. The MI300 has 14,080 shading units, 880 TMUs, and 0 ROPs. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The MI300 has more than double the shading units and more than four times the TMUs, but it has no ROPs, which aligns with its lack of display outputs and rasterization pipeline. The LX MAX implements a conventional graphics pipeline with pixel output capability.

Memory architecture is fundamentally different. The MI300 uses 128 GB of HBM3 on an 8192-bit bus with 5.32 TB/s bandwidth. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The MI300 memory clock is 1300 MHz with 5.2 Gbps effective, while the LX MAX memory clock is 2250 MHz with 18 Gbps effective. The bus width difference is the dominant factor: 8192 bits versus 192 bits is a ratio of roughly 42.7 to 1, which explains the bandwidth gap despite the higher effective memory clock on the LX MAX.

Interface differences are also present. The MI300 uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. The MI300 has no display outputs, no DirectX, OpenGL, or Vulkan support listed. The LX MAX has 4x DisplayPort 1.4a, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The MI300 uses two 8-pin power connectors with a 600 W TDP and a 1000 W suggested PSU. The LX MAX uses one 16-pin power connector with a 225 W TDP and a 550 W suggested PSU.

The MI300 released on 2023-01-03 and has a predecessor listed as Radeon Instinct. The LX MAX released on 2026-03-16, has no predecessor, and its production status is listed as Active. The MI300 production status is not listed. The LX MAX has a dual-slot width listed, while the MI300 has no slot width listed.

The Verdict

The data shows two parts with almost no overlap in intended use. The AMD Instinct MI300 is a high-capacity compute accelerator. It has 128 GB of HBM3, 5.32 TB/s of bandwidth, 47.87 TFLOPS FP32, 1,496.0 GTexel/s texture rate, 14,080 shading units, and a PCIe 5.0 x16 interface. It has no display outputs and no graphics API support. It draws 600 W and requires a 1000 W PSU. It is the choice for workloads that fit in very large memory footprints and need maximum single-precision throughput, memory bandwidth, or texture rate.

The Lisuan Tech LX MAX is a conventional graphics card with compute capability. It has 12 GB of GDDR6, 432.0 GB/s of bandwidth, 49.15 TFLOPS FP16, 24.58 TFLOPS FP32, 192.0 GPixel/s pixel rate, 384.0 GTexel/s texture rate, 96 ROPs, and 6,144 shading units. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, and it has four DisplayPort 1.4a outputs. It draws 225 W and requires a 550 W PSU. It is the choice for any workload that needs a video output, a rendering pipeline, or half-precision peak throughput, and it does so at a much lower power draw.

The MI300 wins on FP32, memory capacity, memory bandwidth, texture rate, shading units, and interface generation. The LX MAX wins on FP16, pixel rate, display outputs, API support, power efficiency, and physical size. The 2:1 FP16 ratio of the LX MAX gives it a peak half-precision figure that exceeds the MI300 despite the MI300 having more than twice the shading units. The MI300 has no ROPs and no pixel output, making it unsuitable for any rasterization task. The LX MAX has no path to large memory capacities, making it unsuitable for workloads that require more than 12 GB.

The release dates place the MI300 in 2023 and the LX MAX in 2026. The MI300 predecessor is Radeon Instinct, while the LX MAX has no predecessor listed. The LX MAX is marked Active in production status; the MI300 has no production status listed. Neither part has measured benchmark scores in the database, so these conclusions rest entirely on the recorded specification data.
