AMD Radeon Instinct MI300 vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the AMD Radeon Instinct MI300 and the Lisuan Tech LX MAX. Both entries show an average benchmark score of 0 and a percentile rank of 50 against all GPUs, meaning no measured performance data exists for either product in the database. Consequently, the win counts stand at 0 for both parts.

Without direct scores, the comparison rests on the compute specifications each manufacturer lists. The AMD Radeon Instinct MI300 delivers 47.87 TFLOPS of FP32 compute and 383.0 TFLOPS of FP16 compute using an 8:1 ratio. The Lisuan Tech LX MAX provides 24.58 TFLOPS of FP32 and 49.15 TFLOPS of FP16 with a 2:1 ratio. The MI300's FP32 figure is roughly double that of the LX MAX, while its FP16 output is nearly eight times higher. Those are the only numeric performance indicators available, and they come from the specification sheets, not from executed benchmarks.

The texture rate tells a similar story. The MI300 reaches 1,496.0 GTexel/s, while the LX MAX manages 384.0 GTexel/s. That places the AMD part ahead by a factor of nearly four in texture fill. Pixel rate, however, favors the Lisuan product: the LX MAX outputs 192.0 GPixel/s, while the MI300 is listed at 0 MPixel/s, which reflects its lack of display outputs and its data-center orientation.

Memory bandwidth is another decisive gap. The MI300 uses 128 GB of HBM3 on an 8192-bit bus, yielding 6.55 TB/s. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The MI300's bandwidth is over 15 times higher. That gap directly affects any workload that saturates memory, such as large matrix operations or massive dataset processing.

The conclusion from the recorded data is that the MI300 dominates in raw compute throughput, texture rate, and memory bandwidth, while the LX MAX leads in pixel output and offers a more conventional display-capable feature set. No benchmark evidence exists to alter that picture.

Where Each One Wins

The AMD Radeon Instinct MI300 wins decisively in compute-heavy and memory-bound scenarios. Its FP32 output of 47.87 TFLOPS doubles the LX MAX's 24.58 TFLOPS. FP16 performance is even more lopsided: 383.0 TFLOPS versus 49.15 TFLOPS. Texture rate follows the same pattern, 1,496.0 GTexel/s against 384.0 GTexel/s, which makes the MI300 the stronger choice for workloads that rely heavily on texture sampling, such as certain simulation or rendering pipelines. Memory capacity and bandwidth also favor the MI300 heavily. With 128 GB of HBM3 and 6.55 TB/s, it can hold far larger datasets and feed compute units faster than the LX MAX's 12 GB GDDR6 at 432.0 GB/s. The 8192-bit bus versus 192-bit bus underscores the architectural intent: the MI300 is built for massive parallel data movement.

The Lisuan Tech LX MAX wins in areas that the MI300 does not address at all. It provides 4x DisplayPort 1.4a outputs, making it suitable for direct display connection, while the MI300 has no outputs. Its pixel rate of 192.0 GPixel/s, compared to the MI300's 0 MPixel/s, confirms that the LX MAX is a rasterization-capable part. The LX MAX also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the MI300 lists no API support. For any workload that requires rendering to a screen or using graphics APIs, the LX MAX is the only one of the two that fits. The LX MAX also runs at a lower TDP of 225 W versus 600 W, and fits in a dual-slot design with a 248 mm length, which eases installation in conventional systems.

The data shows a clear split: the MI300 is a data-center compute accelerator, and the LX MAX is a display-oriented GPU with more modest compute. Neither product covers the other's primary territory.

Specification Differences

The two products differ across nearly every listed specification. The MI300 uses a 5 nm process node from TSMC, while the LX MAX uses 6 nm, also from TSMC. Transistor count is 153,000 million for the MI300, with a die size of 1017 mm² and a transistor density of 150.4M per mm². The LX MAX lists unknown transistor count, die size, and density.

Clock speeds differ in structure. The MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz, plus a memory clock of 1600 MHz with 6.4 Gbps effective. The LX MAX lists no base or boost clock, but a memory clock of 2250 MHz with 18 Gbps effective.

Memory configuration is starkly different: 128 GB HBM3 on an 8192-bit bus with 6.55 TB/s for the MI300, versus 12 GB GDDR6 on a 192-bit bus with 432.0 GB/s for the LX MAX. Shading units number 14080 on the MI300 and 6144 on the LX MAX. Texture mapping units are 880 versus 192. Raster operation units are 0 on the MI300 and 96 on the LX MAX. Pixel rate is 0 MPixel/s versus 192.0 GPixel/s. Texture rate is 1,496.0 GTexel/s versus 384.0 GTexel/s. FP32 is 47.87 TFLOPS versus 24.58 TFLOPS. FP16 is 383.0 TFLOPS (8:1) versus 49.15 TFLOPS (2:1).

Power and physical specifications also diverge. TDP is 600 W for the MI300 and 225 W for the LX MAX. Power connectors are 2x 8-pin versus 1x 16-pin. Suggested PSU is 1000 W versus 550 W. Bus interface is PCIe 5.0 x16 for the MI300 and PCIe 4.0 x16 for the LX MAX. Display outputs are absent on the MI300 and present as 4x DisplayPort 1.4a on the LX MAX. The MI300 lists no DirectX, OpenGL, or Vulkan support; the LX MAX lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. Dimensions are 267 mm length and 111 mm height for the MI300, with no width, versus 248 mm length, 118 mm height, and 48 mm width for the LX MAX, which also specifies a dual-slot form factor. The LX MAX is marked Active in production status; the MI300 has no production status listed. Release dates are 2023-01-03 for the MI300 and 2026-03-16 for the LX MAX. Neither product has a listed launch MSRP.

Architecture Differences

The AMD Radeon Instinct MI300 is built on the CDNA 3.0 architecture with the Aqua Vanjaram chip, belonging to the Radeon Instinct (MIx) generation. The Lisuan Tech LX MAX uses the TrueGPU architecture with the 7G106 chip, belonging to the 7G100 generation. These are fundamentally different design philosophies. CDNA 3.0 is AMD's compute-focused architecture lineage, optimized for data-center workloads rather than graphics output. TrueGPU, as named, appears oriented toward general graphics processing, given its display outputs, API support, and raster operation units.

The process nodes differ: 5 nm for the MI300, 6 nm for the LX MAX, both fabricated by TSMC. The MI300 integrates 153,000 million transistors on a 1017 mm² die, a massive chip designed for maximum compute density. The LX MAX does not disclose transistor count or die size in the database. The MI300's transistor density of 150.4M per mm² reflects the tight packing on a leading-edge node.

Core organization differs substantially. The MI300 has 14080 shading units, 880 TMUs, and 0 ROPs. The lack of ROPs aligns with its no-display-output design; rasterization is not a function it performs. The LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs, a conventional graphics-oriented configuration that allows pixel output at 192.0 GPixel/s. Neither product lists ray tracing cores or tensor cores.

Memory architecture also reflects the different targets. The MI300's HBM3 stack on an 8192-bit bus is characteristic of compute accelerators that need enormous bandwidth for large working sets. The LX MAX's GDDR6 on a 192-bit bus is typical of consumer or workstation GPUs where capacity and cost are secondary to bandwidth. The MI300's FP16 implementation uses an 8:1 ratio, meaning it achieves 383.0 TFLOPS by trading away compute precision for throughput. The LX MAX uses a 2:1 ratio for 49.15 TFLOPS, indicating a more conservative FP16 path.

Both products use PCIe, but at different generations: 5.0 x16 for the MI300, 4.0 x16 for the LX MAX. The MI300's newer bus interface supports faster host transfer speeds, though no benchmark data confirms real-world impact. The LX MAX's slot width is dual-slot, while the MI300's is not listed.

The Verdict

The data indicates two products with almost no overlap in purpose. The AMD Radeon Instinct MI300 is built for compute throughput and massive memory capacity. Its 47.87 TFLOPS FP32, 383.0 TFLOPS FP16, 128 GB HBM3, and 6.55 TB/s bandwidth place it firmly in data-center acceleration territory. It offers no display outputs, no graphics API support, and no raster operations. Its 600 W TDP and 1000 W suggested PSU confirm a server-oriented installation profile. Anyone running FP32 or FP16 compute workloads with large datasets should select the MI300 based on the recorded specifications.

The Lisuan Tech LX MAX is a display-capable GPU with 4x DisplayPort 1.4a outputs, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3 support. Its 192.0 GPixel/s pixel rate and 96 ROPs enable rasterization, which the MI300 cannot perform. Its 24.58 TFLOPS FP32 is still substantial but roughly half the MI300's figure. Its 12 GB GDDR6 and 432.0 GB/s bandwidth are modest next to the MI300 but sufficient for graphics-oriented tasks. The 225 W TDP and dual-slot design make it suitable for conventional workstations or desktop systems. Users who need to render to displays or run graphics APIs should select the LX MAX.

There is no middle ground in the recorded data. The MI300 wins every compute and memory metric. The LX MAX wins every display and graphics API metric. Neither product can substitute for the other in its respective role. The percentile ranks are identical at 50, and average benchmark scores are 0 for both, so the database offers no measured performance evidence to refine this split. The specification sheets alone define the verdict.
