AMD Instinct MI300A vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the AMD Instinct MI300A and the Lisuan Tech LX PRO. Both entries list an average benchmark score of zero and hold a percentile rank of 50 against all GPUs, which places them at the exact median of the database distribution. Without measured frame rates, compute throughput scores, or synthetic test results, a numerical comparison of their actual performance output is not possible from the available data.

What the data does confirm is a massive gap in raw compute specifications. The AMD Instinct MI300A delivers 61.29 TFLOPS of FP32 performance, while the Lisuan Tech LX PRO produces 24.58 TFLOPS under the same precision. That puts the MI300A at roughly 2.5 times the FP32 throughput of the LX PRO. In FP16, the LX PRO reaches 49.15 TFLOPS using a 2:1 ratio, but the MI300A has no recorded FP16 figure, so a direct comparison in reduced precision cannot be made.

Memory bandwidth tells a similarly lopsided story. The MI300A accesses 5.32 TB/s through an 8192-bit HBM3 interface, whereas the LX PRO manages 432.0 GB/s over a 192-bit GDDR6 bus. The MI300A offers more than twelve times the memory bandwidth of its rival, a decisive advantage for bandwidth-bound workloads such as large matrix operations or data-parallel compute kernels.

Texture and pixel throughput also differ sharply. The MI300A produces 1,915.2 GTexel/s from 912 texture mapping units, while the LX PRO generates 384.0 GTexel/s from 192 TMUs. The LX PRO counters with a 192.0 GPixel/s pixel rate from 96 ROPs, while the MI300A lists 0 MPixel/s, indicating it has no raster operation pipeline at all. The MI300A is a compute accelerator without display outputs, while the LX PRO is a full graphics card with four DisplayPort 1.4a connectors.

Clock behavior separates the two as well. The MI300A runs at a 1000 MHz base clock and boosts to 2100 MHz. The LX PRO has no recorded base or boost clocks for its core, only a memory clock of 2250 MHz with 18 Gbps effective transfer. This absence of core clock data for the LX PRO limits any frequency-based analysis.

Architecture Differences

The two devices come from fundamentally different architectural lineages. The AMD Instinct MI300A uses the CDNA 3.0 architecture on a chip codenamed Aqua Vanjaram, manufactured on a 5 nm TSMC process. It belongs to the Instinct (MIx) generation and succeeds the Radeon Instinct line. The Lisuan Tech LX PRO uses a TrueGPU architecture on a chip labeled 7G105, built on a 6 nm TSMC node, and belongs to the 7G100 generation.

Transistor counts reveal the scale disparity. The MI300A packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The LX PRO lists its transistor count and die size as unknown, so no density figure can be computed. The MI300A's die is a massive monolithic slab, among the largest in the database, while the LX PRO's physical dimensions are a standard dual-slot card measuring 248 mm in length, 118 mm in height, and 48 mm in width.

Memory architecture differs completely. The MI300A uses 128 GB of HBM3 across an 8192-bit bus. The LX PRO uses 24 GB of GDDR6 across a 192-bit bus. HBM3 is stacked memory designed for bandwidth density, while GDDR6 is a conventional discrete memory type. The MI300A's 128 GB capacity is more than five times the LX PRO's 24 GB, and its bus width is over forty times wider.

The compute pipelines are organized differently. The MI300A has 14,592 shading units, 912 TMUs, and no ROPs. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. Neither device lists tensor cores or ray tracing cores, so those features are absent from the database. The MI300A's pixel rate is recorded as zero, reinforcing its role as a non-rendering accelerator. The LX PRO's 192.0 GPixel/s pixel rate confirms it can drive a display pipeline.

Power and interface requirements diverge as well. The MI300A draws 750 W and uses an OAM Module slot width with no power connectors listed, suggesting a board-level power delivery system rather than a plug-in card. It requires a suggested PSU of 1150 W and connects via PCIe 5.0 x16. The LX PRO draws 225 W, uses a single 16-pin power connector, requires a suggested PSU of 550 W, and connects via PCIe 4.0 x16. The MI300A has no display outputs and no supported graphics APIs, while the LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

Release timing also differs. The MI300A launched on December 5, 2023. The LX PRO carries a release date of March 16, 2026, and its production status is listed as active. The MI300A has no recorded production status. The LX PRO's launch is over two years later, reflecting a generational gap in design philosophy.

Where Each One Wins

The AMD Instinct MI300A wins decisively in raw compute throughput. Its 61.29 TFLOPS FP32 figure is 2.5 times the LX PRO's 24.58 TFLOPS, and its 1,915.2 GTexel/s texture rate dwarfs the LX PRO's 384.0 GTexel/s. The MI300A also holds a commanding lead in memory capacity and bandwidth: 128 GB versus 24 GB, and 5.32 TB/s versus 432.0 GB/s. These specifications point toward large-scale scientific computing, AI training, and HPC simulation workloads where memory footprint and bandwidth are the primary constraints.

The MI300A's 8192-bit memory bus and HBM3 stack are designed for datasets that exceed the capacity of conventional graphics memory. The 153,000 million transistor count on a 1017 mm² die indicates a device built for maximum parallel computation, not for efficiency or compactness. The absence of ROPs, display outputs, and graphics API support confirms that the MI300A is a server-oriented accelerator, not a consumer graphics card.

The Lisuan Tech LX PRO wins in several areas that matter for workstation and client use. It has a functional raster pipeline with 96 ROPs and a 192.0 GPixel/s pixel rate, enabling actual graphics rendering. Its four DisplayPort 1.4a outputs allow direct monitor connectivity, while the MI300A has none. The LX PRO supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, making it compatible with mainstream graphics software stacks. The MI300A lists no supported APIs.

The LX PRO also wins on power efficiency and physical integration. Its 225 W TDP is exactly one-third of the MI300A's 750 W, and its suggested PSU of 550 W is less than half of the MI300A's 1150 W requirement. The LX PRO fits in a dual-slot PCIe card form factor with a standard 16-pin power connector, while the MI300A uses an OAM Module slot with no discrete power connectors, implying a different chassis and power delivery infrastructure. The LX PRO uses PCIe 4.0 x16, which is a generation older than the MI300A's PCIe 5.0 x16, but its conventional form factor makes it far easier to deploy in standard desktop or workstation systems.

The LX PRO's 6 nm process node is slightly larger than the MI300A's 5 nm node, but its 225 W power envelope allows cooling with a conventional dual-slot design. The MI300A's 750 W draw and OAM form factor require specialized server cooling and power delivery.

The Verdict

The data describes two devices built for entirely different purposes. The AMD Instinct MI300A is a high-bandwidth compute accelerator with 61.29 TFLOPS FP32, 128 GB of HBM3, 5.32 TB/s memory bandwidth, and 1,915.2 GTexel/s texture throughput. Its 750 W power draw, OAM Module form factor, lack of display outputs, and absence of graphics API support place it squarely in the server and HPC segment. It is designed for workloads that saturate memory bandwidth and require massive parallel compute, such as AI training, scientific simulation, and data-center scale processing.

The Lisuan Tech LX PRO is a conventional graphics card with 24.58 TFLOPS FP32, 24 GB of GDDR6, 432.0 GB/s bandwidth, and a full raster pipeline with 96 ROPs and 192.0 GPixel/s pixel rate. Its 225 W TDP, dual-slot design, four DisplayPort outputs, and full graphics API support make it suitable for workstation rendering, content creation, and general GPU compute in a standard PC chassis. Its 49.15 TFLOPS FP16 performance indicates a capability for reduced-precision workloads, but its 24 GB memory capacity and 192-bit bus limit the scale of datasets it can handle.

Users requiring maximum compute density and memory bandwidth should select the MI300A, provided their infrastructure can accommodate an OAM module, 750 W power draw, and 1150 W PSU. Users needing a self-contained graphics card with display outputs, standard PCIe installation, and a 550 W PSU should select the LX PRO. The MI300A's performance advantage in FP32 and bandwidth is substantial, but it comes with the cost of a specialized server platform. The LX PRO's advantage lies in its integration, API compatibility, and conventional power and cooling requirements. Neither device has recorded benchmark scores, so the decision rests entirely on architectural fit and system compatibility.
