AMD Instinct MI350X vs Lisuan Tech LX MAX Comparison

AMD Instinct MI350X and Lisuan Tech LX MAX occupy entirely different positions in the recorded database. The MI350X is a 3 nm accelerator with 16,384 shading units, built on the CDNA 4.0 architecture and designed for compute workloads with no display outputs. The LX MAX is a 6 nm dual-slot graphics card with 6,144 shading units, a TrueGPU architecture, 12 GB of GDDR6 memory, and four DisplayPort 1.4a outputs. The database records no benchmark scores for either product, and the average benchmark score for both is zero. The percentile versus all GPUs is 50 for each, indicating the absence of measured performance data rather than a mid-pack ranking. The head-to-head benchmark array is empty, and neither product has any nearest rivals listed. The analysis below therefore relies strictly on the architectural and specification data recorded in the database.

Where Each One Wins

The AMD Instinct MI350X wins in raw compute throughput and memory capacity. Its FP32 rating is 72.09 TFLOPS, exactly triple the FP32 figure of the Lisuan Tech LX MAX at 24.58 TFLOPS. The FP16 performance tells a more complex story: the MI350X delivers 72.09 TFLOPS with a 1:1 ratio, meaning FP16 and FP32 throughput are identical. The LX MAX produces 49.15 TFLOPS in FP16 using a 2:1 ratio, which indicates its FP16 output is double its FP32 output but still 23 TFLOPS lower than the MI350X's FP16 capability. Texture rate follows the same pattern, with the MI350X at 2,252.8 GTexel/s versus 384.0 GTexel/s for the LX MAX, a factor of 5.86. The MI350X also has 288 GB of HBM3e memory on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The LX MAX has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The memory bandwidth difference is a factor of 18.96.

The Lisuan Tech LX MAX wins in areas that matter for client-side graphics and practical deployment. It has 96 raster operation pipelines, while the MI350X has zero ROPs and a pixel rate of 0 MPixel/s. The LX MAX delivers 192.0 GPixel/s. The LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, whereas the MI350X lists N/A for all three APIs. The LX MAX includes four DisplayPort 1.4a outputs, while the MI350X has no outputs. The LX MAX is a dual-slot card with a 248 mm length, 118 mm height, and 48 mm width, using a single 16-pin power connector. The MI350X is an OAM module with a 102 mm length and 165 mm width, with no power connectors listed. The LX MAX has a suggested power supply of 550 W and a TDP of 225 W. The MI350X has a suggested power supply of 1400 W and a TDP of 1000 W. The LX MAX is listed as Active in production status, while the MI350X has no production status recorded.

Architecture Differences

The process node separates these two designs by a full generation of lithography. The MI350X uses a 3 nm process at TSMC, while the LX MAX uses a 6 nm process, also at TSMC. The MI350X integrates 185,000 million transistors on a die size of 2380 mm², yielding a transistor density of 77.7M per mm². The LX MAX has unknown transistor count and die size in the database, with no density figure recorded. The MI350X uses the CDNA 4.0 architecture, which is designed for Instinct accelerators in the MIx generation. The LX MAX uses the TrueGPU architecture from the 7G100 generation, a naming scheme that does not appear elsewhere in the database.

Memory architecture differs fundamentally. The MI350X uses HBM3e with 288 GB capacity, an 8192-bit bus, and 2000 MHz memory clock resulting in 8 Gbps effective data rate. The LX MAX uses GDDR6 with 12 GB capacity, a 192-bit bus, and 2250 MHz memory clock resulting in 18 Gbps effective data rate. The MI350X memory bandwidth of 8.19 TB/s is 19 times the LX MAX bandwidth of 432.0 GB/s. The MI350X has no pixel rate because it has no ROPs, whereas the LX MAX has 96 ROPs producing 192.0 GPixel/s. The MI350X has 1,024 texture mapping units, while the LX MAX has 192. The shading unit count is 16,384 for the MI350X versus 6,144 for the LX MAX. Neither product lists ray tracing cores or tensor cores in the database.

The bus interface differs as well. The MI350X uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. The form factors are incompatible: the MI350X is an OAM module measuring 102 mm by 165 mm, while the LX MAX is a dual-slot card measuring 248 mm by 118 mm by 48 mm. The MI350X has no power connectors because OAM modules receive power through the baseboard, while the LX MAX has a single 16-pin connector. The LX MAX supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3; the MI350X has no API support listed. The LX MAX has display outputs, the MI350X does not.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between the AMD Instinct MI350X and the Lisuan Tech LX MAX. The head-to-head benchmark array is empty, and both products have zero wins in the winsA and winsB fields. The absence of benchmark data means no direct comparison of measured performance is possible from the recorded information. The only quantitative comparisons available come from the specification fields.

The FP32 compute ratio is the most decisive specification gap. The MI350X delivers 72.09 TFLOPS, which is 2.93 times the LX MAX figure of 24.58 TFLOPS. In FP16, the MI350X delivers 72.09 TFLOPS, while the LX MAX delivers 49.15 TFLOPS, a ratio of 1.47. The texture rate differential is larger: 2,252.8 GTexel/s versus 384.0 GTexel/s, a factor of 5.87. Memory bandwidth shows the widest gap, with 8.19 TB/s versus 432.0 GB/s, a factor of 18.96. The LX MAX has the only pixel rate in the comparison, at 192.0 GPixel/s, because the MI350X is recorded at 0 MPixel/s.

The clock speeds do not align in a way that permits direct comparison. The MI350X has a base clock of 1000 MHz and a boost clock of 2200 MHz. The LX MAX has no base or boost clock recorded, only a memory clock of 2250 MHz. The MI350X memory clock is 2000 MHz with 8 Gbps effective, while the LX MAX memory clock is 2250 MHz with 18 Gbps effective. The LX MAX memory clock runs 250 MHz higher, and its effective data rate is 10 Gbps higher, but the MI350X achieves far higher bandwidth due to the 8192-bit bus width.

Power consumption separates the two in operational terms. The MI350X TDP is 1000 W, with a suggested power supply of 1400 W. The LX MAX TDP is 225 W, with a suggested power supply of 550 W. The MI350X requires 4.44 times the power of the LX MAX. The LX MAX fits in a standard dual-slot PCIe card footprint, while the MI350X requires an OAM module slot. The release dates are also separated: the MI350X has a release date of 2025-06-11, while the LX MAX has a release date of 2026-03-16.

The Verdict

The database shows two products with no recorded benchmark scores and no head-to-head results, so the verdict must rest on the specification data. The AMD Instinct MI350X is a compute accelerator with no display outputs, no graphics API support, and no ROPs. Its strengths are concentrated in FP32 throughput, memory capacity, and memory bandwidth. The FP32 figure of 72.09 TFLOPS is nearly three times the LX MAX, and the 8.19 TB/s memory bandwidth is nearly nineteen times. The 288 GB HBM3e capacity dwarfs the 12 GB GDDR6 of the LX MAX. The 1000 W TDP and 1400 W suggested power supply reflect the scale of this accelerator. The 3 nm process with 185,000 million transistors on a 2380 mm² die indicates a design aimed at maximum compute density.

The Lisuan Tech LX MAX is a client graphics card. It has 96 ROPs, 192.0 GPixel/s pixel rate, four DisplayPort 1.4a outputs, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support. Its 225 W TDP and 550 W suggested power supply fit a standard dual-slot PCIe card. The 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 figures are lower than the MI350X but represent a usable range for a 6 nm part with 6,144 shading units. The 12 GB GDDR6 memory on a 192-bit bus provides 432.0 GB/s, sufficient for a card of this class. The LX MAX is listed as Active in production, and its release date is 2026-03-16.

The selection depends on the workload. The MI350X is the only choice for applications requiring massive memory capacity, extreme memory bandwidth, or FP32 throughput above 24.58 TFLOPS. The LX MAX is the only choice for any workload requiring display output, graphics API support, or rasterization capability. The MI350X cannot render to a screen, and the LX MAX cannot match the MI350X in compute or memory. The database records no evidence that either product can substitute for the other. For compute density, the MI350X wins on every recorded compute metric. For graphics functionality, the LX MAX wins on every recorded graphics metric. The empty benchmark arrays mean no measured performance confirmation exists for either product, so the specification differences are the sole basis for differentiation.
