AMD Instinct MI355X vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI355X and the Lisuan Tech LX 7G100 contains no benchmark scores, no average scores, and no head-to-head benchmark entries. Both entries show an average benchmark score of zero, and the wins count for each product is zero. The percentile versus all GPUs for both is 50, indicating they sit at the median of the database distribution, though this statistic is identical for both and therefore does not separate them.

Without benchmark results, the only measurable comparison available comes from the specification sheet. The AMD Instinct MI355X delivers 78.64 TFLOPS of FP32 compute, while the Lisuan Tech LX 7G100 provides 24.58 TFLOPS. That difference is a factor of 3.2 in raw FP32 throughput. In FP16, the MI355X again posts 78.64 TFLOPS with a 1:1 ratio, whereas the LX 7G100 reaches 49.15 TFLOPS with a 2:1 ratio, meaning the Lisuan part performs FP16 at twice its FP32 rate. Even with that advantage, the MI355X still leads FP16 by roughly 1.6 times.

Texture rate follows the same pattern. The MI355X processes 2,457.6 GTexel/s, while the LX 7G100 manages 384.0 GTexel/s, a 6.4 times margin. Pixel rate tells a different story: the MI355X lists 0 MPixel/s, because it has no ROPs, whereas the LX 7G100 has 96 ROPs and a pixel rate of 192.0 GPixel/s. In any rasterization workload that depends on pixel output, the Lisuan product is the only one of the two with any capability.

Memory bandwidth separates the two even more sharply. The MI355X uses 288 GB of HBM3e on a 8192 bit bus, producing 8.19 TB/s. The LX 7G100 has 12 GB of GDDR6 on a 192 bit bus, producing 432.0 GB/s. The AMD part has 19 times the bandwidth and 24 times the memory capacity. The memory clock figures are 2000 MHz (8 Gbps effective) for the MI355X and 2250 MHz (18 Gbps effective) for the LX 7G100, so the GDDR6 runs at a higher effective data rate, but the bus width difference overwhelms that.

Shading units count 16384 on the MI355X versus 6144 on the LX 7G100. TMUs are 1024 versus 192. These raw counts align with the compute and texture rate measurements. The MI355X has no ROPs, no display outputs, and no API support for DirectX, OpenGL, or Vulkan, all listed as N/A. The LX 7G100 has 96 ROPs, four DisplayPort 1.4a outputs, and full API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

The Verdict

The data indicates two products built for entirely different purposes. The AMD Instinct MI355X is a compute accelerator with no display path, no raster output, and no consumer graphics API support. The Lisuan Tech LX 7G100 is a conventional graphics card with display outputs, a dual-slot form factor, and a 225 W TDP that fits in a standard PCIe 4.0 x16 slot with one 8-pin power connector and a 550 W suggested PSU.

For anyone processing FP32 or FP16 workloads, the MI355X is the clear choice based on raw throughput, memory bandwidth, and capacity. It delivers 78.64 TFLOPS in both FP32 and FP16, has 8.19 TB/s of bandwidth, and offers 288 GB of HBM3e. The LX 7G100 cannot match any of those figures.

For anyone needing to output pixels to a display, the LX 7G100 is the only viable option. The MI355X has no display outputs and a pixel rate of 0 MPixel/s. The Lisuan part provides 192.0 GPixel/s, supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, and includes four DisplayPort 1.4a connectors.

The TDP difference is also decisive. The MI355X requires a 1400 W TDP and an 1800 W suggested PSU, while the LX 7G100 needs only 225 W and a 550 W PSU. The MI355X uses an OAM Module slot width with no power connectors listed, meaning it is not designed for a desktop motherboard. The LX 7G100 is a dual-slot card measuring 294 mm in length, 120 mm in height, and 49 mm in width, which is a standard graphics card footprint.

Neither product has launch MSRP data, so no pricing comparison is possible. The percentile ranking of 50 for both indicates they are not outliers in the database, but with no benchmark scores, that ranking carries no further meaning.

Architecture Differences

The AMD Instinct MI355X uses the MI350 256CU chip with CDNA 4.0 architecture on a 3 nm TSMC process. The chip contains 185,000 million transistors on a 2380 mm² die, giving a transistor density of 77.7 million per square millimeter. The Lisuan Tech LX 7G100 uses the 7G106 chip with TrueGPU architecture on a 6 nm TSMC process. Its transistor count and die size are listed as unknown.

The MI355X belongs to the Instinct (MIx) generation and was released on 2025-06-11, with the Radeon Instinct series as its predecessor. The LX 7G100 belongs to the 7G100 generation and was released on 2026-06-17, with no predecessor listed. The Lisuan part has an active production status, while the MI355X production status is not recorded.

Memory architecture differs completely. The MI355X uses HBM3e with a 8192 bit bus, while the LX 7G100 uses GDDR6 with a 192 bit bus. The MI355X memory runs at 2000 MHz with 8 Gbps effective speed, and the LX 7G100 runs at 2250 MHz with 18 Gbps effective speed. The MI355X has no ROPs, while the LX 7G100 has 96. The MI355X has no RT cores or tensor cores listed for either product, so no comparison is possible there.

The power delivery is also different. The MI355X lists no power connectors because it is an OAM Module, and its suggested PSU is 1800 W. The LX 7G100 uses one 8-pin connector and a 550 W suggested PSU. The MI355X dimensions are 102 mm length and 165 mm width, while the LX 7G100 is 294 mm long, 120 mm tall, and 49 mm wide.

The bus interface differs as well. The MI355X uses PCIe 5.0 x16, while the LX 7G100 uses PCIe 4.0 x16. The MI355X has no display outputs, while the LX 7G100 has four DisplayPort 1.4a outputs. The MI355X has no API support for DirectX, OpenGL, or Vulkan, while the LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.
