AMD Radeon Instinct MI300A vs Lisuan Tech LX PRO Comparison

FAQ

Q: What are the core architectural differences between the AMD Radeon Instinct MI300A and the Lisuan Tech LX PRO?

A: The MI300A uses AMD's CDNA 3.0 architecture on a 5 nm TSMC process, while the LX PRO uses the TrueGPU architecture on a 6 nm TSMC process. The MI300A is built for data center compute with no display outputs, whereas the LX PRO is a dual-slot card with four DisplayPort 1.4a outputs and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 API support.

Q: How do the memory subsystems compare?

A: The MI300A has 192 GB of HBM3 memory on an 8192-bit bus with 10.3 TB/s of bandwidth. The LX PRO has 24 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s of bandwidth. The MI300A's memory bandwidth is roughly 24 times higher.

Q: Which card has higher raw compute throughput?

A: The MI300A delivers 81.72 TFLOPS FP32 and 653.7 TFLOPS FP16 (8:1). The LX PRO delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1). The MI300A is about 3.3 times faster in FP32 and roughly 13 times faster in FP16 peak throughput.

Q: What are the power and physical requirements?

A: The MI300A has a 750 W TDP and requires a 1150 W suggested PSU, using an OAM Module slot width with no power connectors. The LX PRO has a 225 W TDP, a 550 W suggested PSU, a dual-slot design with a single 16-pin connector, and measures 248 mm by 118 mm by 48 mm.

Q: Do both cards support the same PCIe interface?

A: No. The MI300A uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The MI300A's interface is one generation newer, which matters for data transfer rates in compatible systems.

Q: What is the production status of each card?

A: The MI300A has no production status listed in the database, while the LX PRO is marked as Active. The MI300A was released on 2023-12-05, and the LX PRO has a release date of 2026-03-16.

Architecture Differences

The AMD Radeon Instinct MI300A and the Lisuan Tech LX PRO target completely different segments, and that is visible in every architectural choice. The MI300A is built on CDNA 3.0, AMD's compute-optimized architecture, using a 5 nm process at TSMC. Its die measures 1017 mm² and packs 153,000 million transistors, yielding a transistor density of 150.4 million per square millimeter. The LX PRO uses the TrueGPU architecture on a 6 nm process, also from TSMC, but its transistor count and die size are listed as unknown in the database.

The MI300A has 19,456 shading units, 1,216 texture mapping units, and no ROPs, which is consistent with a pure compute accelerator. Its pixel rate is listed as 0 MPixel/s because it has no display pipeline. The LX PRO, by contrast, has 6,144 shading units, 192 TMUs, and 96 ROPs, with a pixel rate of 192.0 GPixel/s. The presence of ROPs and display outputs confirms that the LX PRO is designed to drive monitors, whereas the MI300A has no outputs at all.

Memory architecture differs sharply. The MI300A uses 192 GB of HBM3 with an 8192-bit bus and 10.3 TB/s bandwidth, a configuration aimed at large data sets and memory-bandwidth-bound workloads. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth, a typical setup for a graphics card. Memory clocks also differ: the MI300A runs at 2525 MHz with 10.1 Gbps effective, while the LX PRO runs at 2250 MHz with 18 Gbps effective. The GDDR6 runs at a higher effective data rate, but the HBM3 implementation wins decisively on total bandwidth due to the enormous bus width.

The API support tells the same story. The MI300A has no DirectX, OpenGL, or Vulkan versions listed, because it is not intended for graphics rendering. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, making it a fully capable graphics card for modern applications. The MI300A uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. Power delivery also separates them: the MI300A is an OAM module with a 750 W TDP and no power connectors, while the LX PRO is a dual-slot card with a 225 W TDP and one 16-pin connector.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two cards, and neither card has individual benchmark scores or nearest rival entries. The comparison must therefore be drawn from the specification data.

The MI300A dominates in compute throughput. Its FP32 figure of 81.72 TFLOPS is 3.3 times the LX PRO's 24.58 TFLOPS. In FP16, the margin is even wider: 653.7 TFLOPS versus 49.15 TFLOPS, a 13.3 times advantage. The MI300A also leads heavily in texture rate with 2,553.6 GTexel/s versus 384.0 GTexel/s, a 6.65 times difference. Memory bandwidth is the largest gap, with 10.3 TB/s versus 432.0 GB/s.

The LX PRO wins in areas relevant to graphics output. Its pixel rate of 192.0 GPixel/s is meaningful because the MI300A has a pixel rate of 0 MPixel/s. The LX PRO also has display outputs, a functional graphics API stack, and ROPs, all of which the MI300A lacks. The LX PRO is also far more modest in power draw at 225 W versus 750 W, and it fits in a standard dual-slot form factor with a single 16-pin power connector, whereas the MI300A is an OAM module.

The MI300A has a newer PCIe interface at 5.0 x16 versus the LX PRO's 4.0 x16. The LX PRO has a smaller physical footprint at 248 mm by 118 mm by 48 mm, while the MI300A has no dimensions listed. The MI300A's release date is 2023-12-05, and the LX PRO's is 2026-03-16.

The Verdict

The data describes two products with no overlap in purpose. The AMD Radeon Instinct MI300A is a data center accelerator with massive memory capacity, extreme bandwidth, and compute throughput that exceeds the LX PRO by a factor of 3.3 in FP32 and 13.3 in FP16. It also uses a newer process node, a newer PCIe generation, and a larger memory bus. It has no display outputs, no graphics API support, and no ROPs, so it cannot function as a graphics card.

The Lisuan Tech LX PRO is a conventional graphics card. It has 96 ROPs, a 192.0 GPixel/s pixel rate, four DisplayPort 1.4a outputs, and full support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3. Its 24 GB of GDDR6 memory and 432.0 GB/s bandwidth are typical for a high-end consumer or workstation GPU. It draws 225 W, requires a 550 W PSU, and fits in a dual-slot 248 mm form factor. Its production status is Active, while the MI300A has no production status listed.

The MI300A is the correct choice for compute workloads that need large memory pools and massive bandwidth. The LX PRO is the correct choice for graphics rendering and display output. Neither card can substitute for the other.
