Architecture Differences

The AMD Instinct MI350P and the Lisuan Tech LX PRO represent fundamentally different design philosophies. The MI350P is built on CDNA 4.0, AMD's compute-optimized architecture, and uses a 3 nm process at TSMC. The chip, designated MI350 128CU, packs 73,000 million transistors onto a 1190 mm² die, yielding a transistor density of 61.3M per mm². This is a massive, compute-focused silicon with no display outputs and no API support for DirectX, OpenGL, or Vulkan, confirming its role as an accelerator rather than a graphics card.

The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip, fabricated on a 6 nm process at TSMC. Its transistor count and die size are not recorded in the database. The LX PRO is a more conventional GPU design, featuring 4x DisplayPort 1.4a outputs and full support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. This makes it a functional graphics card in addition to a compute device.

The memory architectures diverge sharply. The MI350P uses 144 GB of HBM3e on a 8192-bit bus, achieving 8.19 TB/s of bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s of bandwidth. The MI350P's memory bandwidth is roughly 19 times higher, which is critical for data-intensive workloads. The MI350P also runs its memory at 2000 MHz (8 Gbps effective), while the LX PRO runs at 2250 MHz (18 Gbps effective), though the LX PRO's narrower bus limits total throughput.

Shading resources also differ. The MI350P has 8192 shading units, 512 TMUs, and 0 ROPs, with a texture rate of 1,126.4 GTexel/s and a pixel rate of 0 MPixel/s. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs, with a texture rate of 384.0 GTexel/s and a pixel rate of 192.0 GPixel/s. The MI350P's lack of ROPs reinforces its non-rendering role.

Clock behavior differs as well. The MI350P has a base clock of 1000 MHz and a boost clock of 2200 MHz. The LX PRO has no recorded base or boost clocks in the database. The MI350P also uses a PCIe 5.0 x16 interface, while the LX PRO uses PCIe 4.0 x16.

Where Each One Wins

The benchmark data shows a clear split in workload suitability based on architectural capabilities.

The AMD Instinct MI350P dominates in compute-heavy, memory-bandwidth-bound scenarios. Its 144 GB HBM3E pool with 8.19 TB/s bandwidth is a decisive advantage for large dataset processing, AI training, and scientific simulation. The FP32 throughput of 36.04 TFLOPS outpaces the LX PRO by 47%, and the FP16 throughput matches FP32 at 36.04 TFLOPS (1:1 ratio), which is unusual and indicates a compute-first design. The 8192-bit bus and 8192 shading units provide massive parallel throughput. The MI350P uses a 3 nm process with 73,000 million transistors, a level of integration that supports sustained heavy compute loads. Its 600 W TDP and 1000 W suggested PSU reflect the power appetite required for such performance.

The Lisuan Tech LX PRO wins in conventional graphics and power-constrained environments. It is the only card of the two with display outputs (4x DisplayPort 1.4a) and full API support, making it suitable for rendering, workstation graphics, or any workload requiring a visual output. Its 96 ROPs and 192.0 GPixel/s pixel rate enable rasterization, which the MI350P cannot do at all. The LX PRO also delivers FP16 performance of 49.15 TFLOPS (2:1 ratio), which is actually higher than its own FP32 output and higher than the MI350P's FP16 figure of 36.04 TFLOPS. For mixed-precision workloads where FP16 is acceptable, the LX PRO holds a 36% advantage. Its 225 W TDP and 550 W suggested PSU make it far more manageable in terms of system integration and cooling.

The MI350P has no ROPs, no display outputs, and no graphics API support, so it loses every rendering-related comparison. The LX PRO, with 24 GB of GDDR6 memory, cannot match the MI350P's capacity or bandwidth, so it loses every large-memory compute comparison. The choice hinges on whether the workload requires graphics output and lower power, or massive memory and compute throughput.

Head-to-Head Benchmarks

The database records show no direct head-to-head benchmark entries between these two cards. Both have an average benchmark score of 0 and a percentile rank of 50 against all GPUs. The wins column shows 0 for both sides in the head-to-head comparison. However, the specification data provides clear quantitative deltas that define the competitive landscape.

The largest win for the AMD Instinct MI350P is memory bandwidth. At 8.19 TB/s versus 432.0 GB/s, the MI350P delivers approximately 19 times the bandwidth of the LX PRO. This is the single most decisive gap in the comparison. Similarly, memory capacity favors the MI350P by a factor of 6: 144 GB versus 24 GB.

In FP32 compute, the MI350P achieves 36.04 TFLOPS against 24.58 TFLOPS for the LX PRO, a lead of 47%. The texture rate also favors the MI350P: 1,126.4 GTexel/s versus 384.0 GTexel/s, a 193% advantage. The shading unit count is 8192 versus 6144, a 33% difference.

The Lisuan Tech LX PRO wins in FP16 compute, delivering 49.15 TFLOPS against 36.04 TFLOPS for the MI350P, a 36% advantage. This is notable because the MI350P's FP16 rate is identical to its FP32 rate (1:1), while the LX PRO's FP16 is double its FP32 (2:1). For workloads that can use FP16 precision, the LX PRO offers higher raw throughput.

The LX PRO also wins every graphics-related metric. Its 192.0 GPixel/s pixel rate compares to 0 MPixel/s for the MI350P. Its 96 ROPs compare to 0. Its 4x DisplayPort 1.4a outputs compare to none. The LX PRO also has a lower TDP, 225 W versus 600 W, which is a 62% reduction in power draw, and a lower suggested PSU, 550 W versus 1000 W.

The PCIe interface also differs: the MI350P uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. This gives the MI350P a potential host-interface bandwidth advantage, though no measured transfer rates are recorded in the database.

The physical dimensions favor the LX PRO in length (248 mm versus 267 mm) and height (118 mm versus 111 mm), but the MI350P is thinner (40 mm versus 48 mm). Both are dual-slot cards with a single 16-pin power connector.

The Verdict

The recorded data indicates two entirely different product categories sharing a dual-slot form factor. The AMD Instinct MI350P is an accelerator with no display capability, no graphics API support, and no ROPs. Its purpose is compute, and its specifications confirm this: 144 GB of HBM3e, 8.19 TB/s of bandwidth, 36.04 TFLOPS of FP32, and a 600 W TDP. It targets workloads where memory capacity and bandwidth are the primary constraints, such as large-scale AI training, scientific simulation, or data analytics. The 3 nm process and 73,000 million transistors place it at the high end of silicon integration.

The Lisuan Tech LX PRO is a conventional GPU with full graphics functionality. Its 24 GB of GDDR6, 432.0 GB/s of bandwidth, and 24.58 TFLOPS of FP32 are modest in comparison to the MI350P, but it offers 4x DisplayPort 1.4a outputs, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support. Its 96 ROPs and 192.0 GPixel/s pixel rate enable real-time rendering. Its 225 W TDP makes it substantially easier to integrate into a workstation or desktop system.

The data shows that the MI350P wins all memory-capacity and memory-bandwidth comparisons, all FP32 compute comparisons, and all texture-rate comparisons. The LX PRO wins all graphics-output comparisons, all rasterization comparisons, the FP16 compute comparison, and the power-efficiency comparison. Neither card is a substitute for the other. The MI350P cannot output video, and the LX PRO cannot match the MI350P's memory subsystem.

For a user whose workload is pure compute with no display requirement, the MI350P is the only choice between these two based on the recorded metrics. For a user who needs a graphics card with compute capability, the LX PRO is the only functional option. The MI350P's release date of 2026-05-06 is later than the LX PRO's 2026-03-16, and the LX PRO is marked as Active in production while the MI350P's production status is not specified. The database shows both cards at the same percentile rank of 50 and the same average benchmark score of 0, reflecting the absence of measured benchmark results. The specification deltas, however, provide a clear verdict: compute versus graphics, scale versus efficiency.
