AMD Radeon Instinct MI300 vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data shows no head-to-head benchmark scores for either the AMD Radeon Instinct MI300 or the Lisuan Tech LX 7G100. Both entries carry an average benchmark score of 0 and a percentile rank of 50 among all GPUs in the database. With zero wins recorded for each side, the direct performance comparison is entirely absent from the dataset. The absence of measured results means the two accelerators cannot be ranked against each other through synthetic workloads or game-level tests. Instead, the comparison must rest entirely on the architectural specifications and theoretical throughput figures recorded in the database.

The most significant arithmetic gap appears in FP32 compute. The MI300 delivers 47.87 TFLOPS, while the LX 7G100 provides 24.58 TFLOPS. That puts the AMD part at roughly 1.95 times the single-precision throughput of the Lisuan accelerator, nearly double. In FP16, the difference widens dramatically. The MI300 reaches 383.0 TFLOPS using an 8:1 ratio, whereas the LX 7G100 reaches 49.15 TFLOPS using a 2:1 ratio. The MI300 therefore offers about 7.8 times the half-precision throughput on paper. Texture rate tells a similar story: 1,496.0 GTexel/s for the MI300 versus 384.0 GTexel/s for the LX 7G100, a 3.9 times advantage. Pixel rate is the single metric where the LX 7G100 records a non-zero value: 192.0 GPixel/s against 0 MPixel/s for the MI300. The MI300 lists no ROPs, which explains why its pixel rate is recorded as zero. The LX 7G100 has 96 ROPs, so it can rasterize frames, while the MI300 is a compute-oriented device with no display outputs and no pixel pipeline.

Memory bandwidth also separates the two decisively. The MI300 has 128 GB of HBM3 on an 8192-bit bus, yielding 6.55 TB/s. The LX 7G100 has 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The MI300 bandwidth is about 15.2 times higher. The LX 7G100 memory clock is recorded at 2250 MHz with 18 Gbps effective, while the MI300 memory runs at 1600 MHz with 6.4 Gbps effective. The effective data rate favors the Lisuan part, but the enormous bus width of the MI300 overwhelms that difference.

Architecture Differences

The two devices are built on different process nodes from the same foundry. The MI300 uses a 5 nm process at TSMC, while the LX 7G100 uses a 6 nm process at TSMC. The MI300 die is 1017 mm² and contains 153,000 million transistors, giving a density of 150.4 million transistors per square millimeter. The LX 7G100 has no recorded transistor count or die size, so its density cannot be calculated. The MI300 chip is named Aqua Vanjaram and uses the CDNA 3.0 architecture. The LX 7G100 chip is named 7G106 and uses an architecture the database calls TrueGPU. The MI300 belongs to the Radeon Instinct (MIx) generation, while the LX 7G100 belongs to the 7G100 generation.

Compute unit composition differs sharply. The MI300 has 14,080 shading units, 880 texture mapping units, and zero ROPs. The LX 7G100 has 6,144 shading units, 192 TMUs, and 96 ROPs. Neither part records dedicated ray tracing cores or tensor cores. The MI300 has no DirectX, OpenGL, or Vulkan API support listed, and no display outputs. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, and outputs through 4x DisplayPort 1.4a. The MI300 is a pure accelerator with no rasterization or display path, while the LX 7G100 is a full graphics-capable card.

Memory architecture also differs. The MI300 uses HBM3 with a 8192-bit bus and 6.55 TB/s bandwidth. The LX 7G100 uses GDDR6 with a 192-bit bus and 432.0 GB/s. The MI300 has 128 GB capacity, the LX 7G100 has 12 GB. The interface generation differs: PCIe 5.0 x16 for the MI300 versus PCIe 4.0 x16 for the LX 7G100. Power requirements are far apart, with the MI300 rated at 600 W and the LX 7G100 at 225 W. The MI300 uses 2x 8-pin power connectors, the LX 7G100 uses 1x 8-pin. The suggested power supply is 1000 W for the MI300 and 550 W for the LX 7G100.

Physical dimensions vary. The MI300 is 267 mm long, 10.5 inches, and 111 mm high, 4.4 inches. The LX 7G100 is 294 mm long, 11.6 inches, 120 mm high, 4.7 inches, and 49 mm wide, 1.9 inches, with a dual-slot profile. The MI300 has no recorded width or slot width. Release dates differ by more than three years. The MI300 launched on January 3, 2023, and its predecessor is listed as FirePro Data Center. The LX 7G100 launched on June 17, 2026, and its production status is Active. The MI300 production status is not recorded. Neither device has a successor listed.

Where Each One Wins

The MI300 wins in every compute-heavy metric recorded. FP32 throughput is 47.87 TFLOPS versus 24.58 TFLOPS. FP16 throughput is 383.0 TFLOPS versus 49.15 TFLOPS. Texture rate is 1,496.0 GTexel/s versus 384.0 GTexel/s. Memory capacity is 128 GB versus 12 GB. Memory bandwidth is 6.55 TB/s versus 432.0 GB/s. The bus width of 8192 bit versus 192 bit gives the MI300 a structural advantage for large data movement. The PCIe 5.0 x16 interface provides twice the generation bandwidth of PCIe 4.0 x16, though no measured transfer rates are recorded.

The LX 7G100 wins in specific areas that matter for conventional graphics workloads. It has 96 ROPs and a recorded pixel rate of 192.0 GPixel/s, while the MI300 has zero ROPs and zero pixel rate. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, all of which are absent from the MI300 record. It has 4x DisplayPort 1.4a outputs, while the MI300 has none. Its memory clock of 2250 MHz with 18 Gbps effective is higher than the MI300 memory clock of 1600 MHz with 6.4 Gbps effective, though the narrower bus limits total bandwidth. The LX 7G100 also has a lower TDP of 225 W versus 600 W, and a lower suggested PSU of 550 W versus 1000 W, which indicates a much lighter power delivery requirement.

The MI300 has no display outputs and no rasterization pipeline, so it cannot act as a graphics card in any traditional sense. The LX 7G100 is a complete graphics solution with modern API coverage and multiple display connections. The MI300 is built around raw compute throughput and massive memory capacity, which suits data center workloads. The LX 7G100 is built around balanced graphics and compute with a 2:1 FP16 ratio, which suits client-side rendering and lighter compute tasks.

The Verdict

The data clearly separates these two products into different categories. The AMD Radeon Instinct MI300 is a high-bandwidth, high-throughput accelerator with 128 GB of HBM3, 6.55 TB/s of bandwidth, and 47.87 TFLOPS of FP32 compute. It has no ROPs, no display outputs, and no graphics API support. The Lisuan Tech LX 7G100 is a graphics-capable card with 96 ROPs, 4x DisplayPort 1.4a, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 support, at 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16.

Any user needing rasterization, display output, or modern graphics APIs should select the LX 7G100, since the MI300 offers none of those features. Any workload centered on FP16 throughput, massive memory capacity, or extreme memory bandwidth should select the MI300, which leads by roughly 7.8 times in FP16, 10.7 times in memory capacity, and 15.2 times in memory bandwidth. The MI300 also has a newer process node at 5 nm versus 6 nm, and a newer PCIe interface at 5.0 x16 versus 4.0 x16.

The LX 7G100 requires a 550 W suggested PSU versus 1000 W for the MI300, and its 225 W TDP is less than half of the MI300 600 W TDP. The LX 7G100 is also physically longer and wider, which affects chassis fit. No benchmark scores exist to verify real-world performance, so all conclusions derive from the specification table. The MI300 is the clear compute leader on paper. The LX 7G100 is the only one of the two that can drive a display.
