AMD Instinct MI355X vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Instinct MI355X or the Lisuan Tech LX PRO. Both entries show an average benchmark score of zero, and the head-to-head benchmark table is empty. Consequently, the percentile ranking for each GPU sits at 50, which in this dataset reflects the absence of measured performance data rather than a position relative to tested rivals. Wins are recorded as zero for both sides.

Without measured frame rates, compute throughput results, or synthetic test outcomes, the comparison must rest entirely on the architectural specifications and the theoretical peak figures listed in the database. The raw numbers, however, point to two devices built for entirely different purposes. The AMD Instinct MI355X delivers 78.64 TFLOPS of FP32 performance and an identical 78.64 TFLOPS of FP16 performance (1:1 ratio). The Lisuan Tech LX PRO produces 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). In raw FP32 throughput, the AMD part leads by a factor of 3.2. In FP16, the AMD lead narrows to 1.6 times, as the Lisuan's 2:1 FP16 ratio doubles its rate relative to its own FP32 figure.

Memory bandwidth tells a similarly lopsided story. The MI355X uses HBM3e across an 8192-bit bus, reaching 8.19 TB/s. The LX PRO relies on GDDR6 across a 192-bit bus, achieving 432.0 GB/s. That is a 19-fold gap in raw bandwidth. The AMD part also carries 288 GB of memory versus 24 GB on the Lisuan, a 12-fold difference in capacity. For any workload that streams large datasets, the MI355X has a structural advantage that no driver or software optimization on the LX PRO could bridge.

Texture and pixel rates follow the same pattern. The MI355X posts a texture rate of 2,457.6 GTexel/s, while the LX PRO manages 384.0 GTexel/s. The AMD card reports a pixel rate of 0 MPixel/s because it has no ROPs configured for display output; the Lisuan part reports 192.0 GPixel/s from its 96 ROPs. That difference is a direct consequence of their design targets: the MI355X is a compute accelerator without display outputs, while the LX PRO is a graphics card with four DisplayPort 1.4a outputs.

Architecture Differences

The two GPUs diverge at every level of their architecture. The AMD Instinct MI355X is built on the CDNA 4.0 architecture, fabricated on a 3 nm process at TSMC. Its chip, designated MI350 256CU, contains 185,000 million transistors on a 2380 mm² die, yielding a transistor density of 77.7 million per mm². The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip, built on a 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown, so no density figure exists in the database.

Shading unit configuration differs massively. The MI355X contains 16,384 shading units and 1,024 TMUs, with zero ROPs. The LX PRO contains 6,144 shading units, 192 TMUs, and 96 ROPs. The AMD part has 2.7 times as many shading units and 5.3 times as many TMUs, but the Lisuan part is the only one with rasterization hardware. Neither card lists RT cores or tensor cores in the database.

Memory architecture reflects their divergent roles. The MI355X pairs 288 GB of HBM3e with an 8192-bit bus and a memory clock of 2000 MHz (8 Gbps effective). The LX PRO pairs 24 GB of GDDR6 with a 192-bit bus and a memory clock of 2250 MHz (18 Gbps effective). The bus width difference of 8192 bits versus 192 bits is the primary driver of the bandwidth gap, and the HBM3e stack layout on the AMD part provides the capacity needed for large model residency.

Clock behavior also differs. The MI355X has a base clock of 1000 MHz and a boost clock of 2400 MHz. The LX PRO has no base or boost clock listed in the database, only its memory clock. The AMD card's boost clock, combined with its massive shading unit count, produces its peak TFLOPS figures.

The MI355X uses a PCIe 5.0 x16 bus interface, while the LX PRO uses PCIe 4.0 x16. The AMD part has no display outputs and no API support (DirectX, OpenGL, and Vulkan are all listed as N/A). The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, and it has four DisplayPort 1.4a outputs.

Physical dimensions differ as well. The MI355X is an OAM module measuring 102 mm in length and 165 mm in width, with no height listed. The LX PRO is a dual-slot card measuring 248 mm in length, 118 mm in height, and 48 mm in width. The power delivery setup also contrasts: the MI355X has no power connectors and a suggested PSU of 1800 W, while the LX PRO uses a single 16-pin connector and a suggested PSU of 550 W.

The Verdict

The data indicates that the AMD Instinct MI355X is a server-oriented compute accelerator with no display functionality. Its 78.64 TFLOPS FP32, 288 GB of HBM3e, and 8.19 TB/s bandwidth position it for dense compute workloads such as large-scale training or inference tasks where memory capacity and bandwidth are the limiting factors. The absence of ROPs, display outputs, and graphics API support confirms that it is not intended for any rasterization or interactive rendering task.

The Lisuan Tech LX PRO, by contrast, is a conventional graphics card with a 24 GB GDDR6 frame buffer, 192.0 GPixel/s pixel throughput, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 output, along with four DisplayPort 1.4a outputs, suit it for graphics rendering, content creation, or compute workloads that fit within 24 GB of memory and do not require extreme bandwidth.

The MI355X leads in every compute and memory metric recorded in the database: FP32 by 3.2 times, FP16 by 1.6 times, texture rate by 6.4 times, memory capacity by 12 times, and memory bandwidth by roughly 19 times. The LX PRO leads in pixel rate (192.0 GPixel/s versus 0 MPixel/s), display outputs (four versus none), and API support. It also operates at a lower TDP of 225 W versus 1400 W, which matters for deployment environments that cannot supply or cool a 1400 W OAM module.

Specification Differences

Transistor count is 185,000 million for the AMD part and unknown for the Lisuan part. Die size is 2380 mm² for the AMD part and unknown for the Lisuan part. The MI355X has 16,384 shading units, 1,024 TMUs, and 0 ROPs; the LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs.

Memory type, size, bus width, and bandwidth all differ: HBM3e 288 GB with 8192-bit bus and 8.19 TB/s for the MI355X; GDDR6 24 GB with 192-bit bus and 432.0 GB/s for the LX PRO. The base and boost clocks are listed only for the MI355X (1000 MHz and 2400 MHz). The memory clock differs: 2000 MHz (8 Gbps effective) versus 2250 MHz (18 Gbps effective).

Pixel rate is 0 MPixel/s for the MI355X and 192.0 GPixel/s for the LX PRO. Texture rate is 2,457.6 GTexel/s versus 384.0 GTexel/s. FP32 is 78.64 TFLOPS versus 24.58 TFLOPS. FP16 is 78.64 TFLOPS (1:1) versus 49.15 TFLOPS (2:1). TDP is 1400 W versus 225 W. Slot width is OAM Module versus Dual-slot. Power connectors are "None" versus "1x 16-pin". Suggested PSU is 1800 W versus 550 W. Bus interface is PCIe 5.0 x16 versus PCIe 4.0 x16. Display outputs are "No outputs" versus "4x DisplayPort 1.4a". API support is N/A for all three APIs on the MI355X, while the LX PRO lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

Dimensions differ in length (102 mm versus 248 mm) and width (165 mm versus 48 mm); only the LX PRO lists a height (118 mm). The release dates differ as well: the MI355X is dated 2025-06-11, while the LX PRO is dated 2026-03-16. The production status is listed as "Active" only for the LX PRO.

Where Each One Wins

The AMD Instinct MI355X wins decisively in any workload that demands raw compute throughput, large memory capacity, or extreme memory bandwidth. Its 78.64 TFLOPS FP32 and FP16 figures, 288 GB of HBM3e, and 8.19 TB/s bandwidth make it the appropriate choice for training large neural networks, processing massive scientific datasets, or serving inference workloads where the model and its working set exceed 24 GB. The PCIe 5.0 x16 interface and 2,457.6 GTexel/s texture rate further support dense matrix and tensor operations that rely on sustained data movement.

The Lisuan Tech LX PRO wins in every scenario that requires display output, rasterization, or graphics API compatibility. Its 192.0 GPixel/s pixel rate, 96 ROPs, and four DisplayPort 1.4a outputs enable direct rendering to monitors. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support mean it can run modern graphics applications, games, or GPU-accelerated content creation tools that require a standard graphics driver stack. Its 24 GB of GDDR6 memory and 432.0 GB/s bandwidth are sufficient for most client-side rendering workloads and for compute tasks that fit within that footprint.

The power envelope also splits the use cases. The LX PRO's 225 W TDP and 550 W suggested PSU fit into standard desktop or workstation builds with conventional power supplies. The MI355X's 1400 W TDP and 1800 W suggested PSU, combined with its OAM module form factor and absence of power connectors, require a server chassis designed for accelerator modules with separate power delivery infrastructure.

The release dates imply different product lifecycles: the MI355X entered the database on 2025-06-11, while the LX PRO is dated 2026-03-16 and carries an active production status. The MI355X lists no production status. For a buyer selecting between them, the deciding factors from the data are clear: compute density and memory scale point to the MI355X, while display capability, graphics API support, and manageable power draw point to the LX PRO.
