AMD Instinct MI308X vs Lisuan Tech LX MAX Comparison

The AMD Instinct MI308X and the Lisuan Tech LX MAX occupy opposite ends of the GPU spectrum. The MI308X is a massive compute accelerator built for data centers, while the LX MAX is a compact consumer graphics card. The recorded data shows they share a 50th percentile standing among all GPUs, but their architectural priorities and performance capabilities diverge dramatically. This analysis breaks down where each part excels based solely on the database specifications.

Where Each One Wins

The AMD Instinct MI308X wins decisively in raw compute throughput and memory capacity. Its FP32 rating of 81.72 TFLOPS is more than triple the LX MAX's 24.58 TFLOPS. The MI308X carries 192 GB of HBM3 memory with a 8192-bit bus, yielding 5.32 TB/s of bandwidth. That is a 12.3x bandwidth advantage over the LX MAX's 432.0 GB/s. The MI308X also holds a massive lead in texture processing, delivering 2,553.6 GTexel/s versus 384.0 GTexel/s.

The Lisuan Tech LX MAX wins in areas that matter for desktop use. It has actual display outputs, with 4x DisplayPort 1.4a, while the MI308X has no outputs. The LX MAX supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3; the MI308X lists N/A for all three APIs. The LX MAX also fits in a standard dual-slot form factor at 248 mm long, whereas the MI308X uses an OAM Module form factor. Pixel throughput goes to the LX MAX at 192.0 GPixel/s, while the MI308X records 0 MPixel/s because it lacks a traditional raster output stage.

Architecture Differences

The MI308X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated by TSMC on a 5 nm process. It contains 153,000 million transistors on a 1017 mm² die, a transistor density of 150.4M per mm². The LX MAX uses the 7G106 chip on the TrueGPU architecture, manufactured by TSMC on a 6 nm node. Its transistor count and die size are unknown in the database.

The MI308X belongs to the Instinct (MIx) generation, a lineage that succeeds Radeon Instinct. The LX MAX belongs to the 7G100 generation. Memory architecture is fundamentally different: the MI308X uses 192 GB of HBM3 on an 8192-bit bus, while the LX MAX uses 12 GB of GDDR6 on a 192-bit bus. The MI308X has no pixel rate capability, indicating it is not designed for rasterized graphics output. The LX MAX includes 96 ROPs and a 192.0 GPixel/s fill rate, confirming a full graphics pipeline.

The MI308X has 19,456 shading units and 1,216 TMUs. The LX MAX has 6,144 shading units and 192 TMUs. The MI308X lists no RT cores or tensor cores. The LX MAX also lists no RT cores or tensor cores, but its DirectX 12 Ultimate support suggests feature-level compatibility. Power delivery differs: the MI308X draws 750 W with no power connectors, relying on the OAM module interface, and requires a suggested 1150 W PSU. The LX MAX draws 225 W, uses a single 16-pin connector, and requires a suggested 550 W PSU.

Head-to-Head Benchmarks

The database records no direct benchmark scores for either GPU, so the comparison relies on specification-derived performance metrics. The FP32 compute gap is the largest single difference. The MI308X delivers 81.72 TFLOPS, which is 3.32x the LX MAX's 24.58 TFLOPS. In FP16, the MI308X again produces 81.72 TFLOPS at a 1:1 ratio, while the LX MAX produces 49.15 TFLOPS at a 2:1 ratio. The MI308X leads FP16 by 1.66x.

Memory bandwidth is the most lopsided comparison. The MI308X's 5.32 TB/s is 12.3x the LX MAX's 432.0 GB/s. That bandwidth advantage directly supports the MI308X's role in large-scale data workloads. The texture rate comparison shows the MI308X at 2,553.6 GTexel/s, a 6.65x lead over the LX MAX's 384.0 GTexel/s. The LX MAX counters with a 192.0 GPixel/s pixel rate, a capability the MI308X lacks entirely at 0 MPixel/s.

The interface generations differ. The MI308X uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. The MI308X memory clock runs at 1300 MHz with 5.2 Gbps effective, while the LX MAX memory clock runs at 2250 MHz with 18 Gbps effective. The LX MAX's faster memory clock per pin does not overcome the MI308X's vastly wider bus. Clock speeds for the LX MAX compute cores are not recorded, so no direct clock comparison is possible.

Specification Differences

The two devices differ in nearly every measurable field. The MI308X uses a 5 nm process; the LX MAX uses 6 nm. The MI308X die is 1017 mm² with 153,000 million transistors; the LX MAX die size and transistor count are unknown. The MI308X has 19,456 shading units versus 6,144. TMUs are 1,216 versus 192. ROPs are 0 versus 96. The MI308X has no display outputs; the LX MAX has 4x DisplayPort 1.4a.

The Verdict

The data points to two tools for two different jobs. The AMD Instinct MI308X is a compute accelerator with 3.32x the FP32 throughput, 6.65x the texture rate, and 12.3x the memory bandwidth of the LX MAX. Its 192 GB HBM3 pool and 8192-bit bus are built for workloads that process massive datasets, such as large-scale inference or scientific simulation. The lack of display outputs and graphics API support confirms it is not a consumer graphics card.

The Lisuan Tech LX MAX is a conventional desktop GPU. It provides full display connectivity, complete graphics API support, and a practical dual-slot footprint. Its 24.58 FP32 TFLOPS and 12 GB GDDR6 memory suit standard rendering and compute tasks. The 225 W TDP means it fits into ordinary desktop power budgets, unlike the MI308X's 750 W module requirement.

Neither part is the right choice for the other's domain. A system builder needing a render output or gaming-capable API stack must choose the LX MAX. A data center workload requiring maximum FP32 throughput and enormous memory bandwidth must choose the MI308X. The database shows no overlap in their intended use cases, and the specification gaps reinforce that separation.
