AMD Instinct MI300A vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Instinct MI300A or the Lisuan Tech LX MAX. Both entries carry an average benchmark score of zero and a percentile rank of 50 against all GPUs, which is a neutral placeholder rather than a measured competitive position. Consequently, there are no direct head-to-head performance comparisons, no win counts for either side, and no delta percentage values from nearest rivals to interpret.

The absence of measured results does not mean the two products are equivalent. The gap in raw compute resources is substantial. The Instinct MI300A lists FP32 throughput of 61.29 TFLOPS, while the LX MAX lists 24.58 TFLOPS. That is a 2.49x difference in single-precision floating-point output, and it is the clearest numeric performance separator in the available data. In FP16, the LX MAX specifies 49.15 TFLOPS with a 2:1 ratio, which is still below the MI300A’s FP32 figure, and the MI300A entry does not list an FP16 value at all.

Texture rate also favors the MI300A heavily: 1,915.2 GTexel/s versus 384.0 GTexel/s for the LX MAX, a 4.99x margin. Pixel rate is inverted, however. The LX MAX delivers 192.0 GPixel/s, while the MI300A lists 0 MPixel/s, effectively no raster output capability. The MI300A is an accelerator without display outputs and without a conventional pixel pipeline, whereas the LX MAX is a Dual-slot graphics card with 4x DisplayPort 1.4a outputs.

Memory bandwidth is another decisive split. The MI300A provides 5.32 TB/s across an 8192-bit HBM3 interface, while the LX MAX provides 432.0 GB/s across a 192-bit GDDR6 interface. That is a 12.31x advantage for the MI300A in raw bandwidth. Capacity differs by an order of magnitude as well: 128 GB versus 12 GB.

Clock behavior is partially specified. The MI300A has a base clock of 1000 MHz and a boost clock of 2100 MHz. The LX MAX does not list base or boost clocks, only a memory clock of 2250 MHz with 18 Gbps effective transfer. The MI300A memory runs at 1300 MHz with 5.2 Gbps effective. Without benchmark scores, clock rates cannot be translated into observed performance, but the memory transfer rates are consistent with the bandwidth figures above.

Architecture Differences

The two devices come from different design philosophies. The AMD Instinct MI300A uses the CDNA 3.0 architecture, built on a 5 nm process at TSMC with the chip codename Aqua Vanjaram. It is part of the Instinct generation (MIx) and follows the Radeon Instinct line. The Lisuan Tech LX MAX uses a TrueGPU architecture, built on a 6 nm process, also at TSMC, with the chip codename 7G106, and belongs to the 7G100 generation. The MI300A carries 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4 million transistors per mm². The LX MAX does not list transistor count, die size, or density in the database.

The MI300A is a compute-oriented accelerator. It has 14,592 shading units, 912 texture mapping units, and zero ROPs. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The MI300A’s ROP count of zero reflects its lack of a rasterization pipeline, consistent with its no-display-output configuration. The LX MAX, by contrast, is a full graphics card with a conventional render output stage.

Memory architecture is fundamentally different. The MI300A uses 128 GB of HBM3 on an 8192-bit bus, yielding 5.32 TB/s. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. HBM3 is a stacked, high-bandwidth memory design; GDDR6 is a discrete, higher-capacity-per-module design. The MI300A’s bus width is 42.67x wider, and its bandwidth is 12.31x higher.

Power delivery and physical format also diverge. The MI300A has a TDP of 750 W, uses an OAM Module slot width, and lists no power connectors. The LX MAX has a TDP of 225 W, uses a Dual-slot form factor, and requires one 16-pin power connector. The suggested power supply ratings follow: 1150 W for the MI300A and 550 W for the LX MAX.

Bus interface differs by one generation. The MI300A uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. The LX MAX provides 4x DisplayPort 1.4a outputs; the MI300A provides no outputs. API support is absent for the MI300A (DirectX N/A, OpenGL N/A, Vulkan N/A), while the LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

Physical dimensions are only recorded for the LX MAX: 248 mm in length, 118 mm in height, and 48 mm in width. The MI300A has no dimensions listed. Release dates are available: the MI300A launched on 2023-12-05, and the LX MAX is dated 2026-03-16. The LX MAX is marked as Active in production status; the MI300A’s status is not specified.

Where Each One Wins

Without benchmark results, the win analysis rests on the recorded specifications. The AMD Instinct MI300A wins decisively in compute throughput, memory bandwidth, and memory capacity. Its FP32 output of 61.29 TFLOPS is 2.49x the LX MAX’s 24.58 TFLOPS. Its texture rate of 1,915.2 GTexel/s is 4.99x higher. Its memory bandwidth of 5.32 TB/s is 12.31x higher, and its 128 GB capacity is 10.67x the LX MAX’s 12 GB. Those figures point to workloads that are memory-bound and compute-bound at scale: large matrix operations, dense linear algebra, and high-volume data movement through an 8192-bit HBM3 interface.

The MI300A also holds the process node advantage. A 5 nm process versus 6 nm, with 153,000 million transistors on a 1017 mm² die, indicates a much larger and more complex chip. The transistor density of 150.4M per mm² confirms that the design packs logic tightly. This is an accelerator built for maximum parallel throughput, not for graphics output.

The Lisuan Tech LX MAX wins in areas that the MI300A does not address at all. It has 96 ROPs and a pixel rate of 192.0 GPixel/s, whereas the MI300A has 0 ROPs and 0 MPixel/s. The LX MAX has display outputs (4x DisplayPort 1.4a), a conventional PCIe 4.0 x16 slot, a Dual-slot cooler, and a 16-pin power connector. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3. The MI300A lists no graphics API support. The LX MAX also has a lower power envelope at 225 W versus 750 W, and a lower suggested PSU at 550 W versus 1150 W.

The LX MAX’s FP16 throughput of 49.15 TFLOPS (2:1) is higher than its own FP32 figure, indicating a ratio-based acceleration path for half-precision workloads. The MI300A does not list an FP16 value, so no comparison is possible there. The LX MAX’s memory clock of 2250 MHz with 18 Gbps effective transfer is higher than the MI300A’s 1300 MHz with 5.2 Gbps effective, but the MI300A compensates with a vastly wider bus.

The production status also differs. The LX MAX is Active; the MI300A’s status is unlisted. The LX MAX has a measurable release date in 2026-03-16, while the MI300A is dated 2023-12-05.

The Verdict

The data describes two devices with almost no overlap in intended function. The AMD Instinct MI300A is a 750 W OAM Module accelerator with no display outputs, no graphics APIs, and no raster pipeline. Its strengths are compute density, memory bandwidth, and memory capacity. The Lisuan Tech LX MAX is a 225 W Dual-slot graphics card with display outputs, full graphics API support, and a conventional power connector. Its strengths are rasterization, graphics compatibility, and lower system power requirements.

For workloads that demand raw FP32 throughput, the MI300A’s 61.29 TFLOPS is the only recorded figure of its kind in this comparison. For workloads that demand memory bandwidth, the MI300A’s 5.32 TB/s is unmatched by the LX MAX’s 432.0 GB/s. For workloads that need 128 GB of on-board memory, the MI300A is the only option here. The LX MAX cannot approach those figures; its 24.58 TFLOPS, 432.0 GB/s, and 12 GB are each an order of magnitude or more behind.

For workloads that require a graphics pipeline, the LX MAX is the only viable choice. It has 96 ROPs, a pixel rate of 192.0 GPixel/s, 4x DisplayPort 1.4a outputs, and DirectX 12 Ultimate support. The MI300A has zero ROPs, zero pixel rate, no display outputs, and no graphics APIs. A system that must render to a screen or run a DirectX/Vulkan application cannot use the MI300A for that purpose.

The power difference is meaningful for system design. The MI300A requires a suggested PSU of 1150 W and has no power connectors, meaning it relies on the OAM module slot for power delivery. The LX MAX requires a 550 W PSU and uses a single 16-pin connector. The MI300A’s 750 W TDP is 3.33x the LX MAX’s 225 W.

The database contains no measured benchmark scores for either product, so relative performance cannot be quantified beyond the specification sheet. The percentile rank of 50 for both is a neutral default, not a measured outcome. Buyers choosing between these two should do so based on the functional requirements above, not on any recorded test results.
