AMD Instinct MI300 vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data for both the AMD Instinct MI300 and the Lisuan Tech LX 7G100 shows no completed benchmark runs in the database. Both parts carry an average benchmark score of zero, and neither has any head-to-head benchmark entries logged against the other. The percentile versus all GPUs is identical at 50 for both, indicating that without measured performance data, the database assigns them the same neutral standing.

Despite the absence of direct benchmark scores, the specification sheets provide enough raw performance indicators to project relative capability. The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 throughput, while the Lisuan Tech LX 7G100 delivers 24.58 TFLOPS. That places the MI300 at roughly 1.95 times the single-precision compute rate of the LX 7G100. In FP16, the MI300 sustains 47.87 TFLOPS at a 1:1 ratio, whereas the LX 7G100 reaches 49.15 TFLOPS using a 2:1 ratio, meaning the Lisuan part actually exceeds the AMD accelerator in half-precision throughput by about 2.7 percent when the 2:1 rate is used.

Texture processing shows a similar gap to FP32. The MI300 achieves a texture fill rate of 1,496.0 GTexel/s, compared to 384.0 GTexel/s for the LX 7G100. That is a 3.9x advantage for the AMD part. Pixel throughput tells a different story: the MI300 reports 0 MPixel/s with no ROPs, while the LX 7G100 has 96 ROPs and a pixel rate of 192.0 GPixel/s. The Lisuan card is the only one of the two able to rasterize frames, as the MI300 has no display outputs and is not designed for graphics output.

Memory bandwidth is another decisive split. The MI300 pairs 128 GB of HBM3 with an 8192-bit bus, yielding 5.32 TB/s of bandwidth. The LX 7G100 uses 12 GB of GDDR6 on a 192-bit bus, producing 432.0 GB/s. The AMD accelerator carries 12.3 times the memory bandwidth of the Lisuan part. That bandwidth disparity will dominate workloads that stream large datasets, such as training runs or inference batches, while the LX 7G100's smaller memory footprint and narrower bus will limit its ceiling in those scenarios.

Clock behavior also differs sharply. The MI300 has a base clock of 1000 MHz and a boost clock of 1700 MHz. The LX 7G100 lists no base or boost clock values in the database, so its operating frequency cannot be directly compared. Memory clock rates diverge as well: the MI300 runs memory at 1300 MHz with 5.2 Gbps effective, while the LX 7G100 runs memory at 2250 MHz with 18 Gbps effective. The GDDR6 memory on the Lisuan card operates at a higher effective data rate per pin, but the much wider HBM3 interface on the MI300 overwhelms that advantage.

The Verdict

The data points to a clear split in intended roles. The AMD Instinct MI300 is a compute accelerator built for massive parallel throughput, evidenced by its 14080 shading units, 880 texture mapping units, 128 GB of HBM3, and 5.32 TB/s of memory bandwidth. Its 47.87 TFLOPS FP32 and 1,496.0 GTexel/s texture rates place it firmly in the high-end compute segment. The Lisuan Tech LX 7G100, with 6144 shading units, 192 TMUs, 96 ROPs, and 12 GB of GDDR6, is a smaller, lower-power device that still supports a full graphics API stack including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3.

For workloads that depend on FP32 matrix operations, large memory footprints, or extreme memory bandwidth, the MI300 is the superior choice by a wide margin. Its FP32 compute is 1.95x higher, its texture rate is 3.9x higher, and its memory bandwidth is 12.3x higher. The MI300 also draws 600 W versus 225 W for the LX 7G100, so the performance advantage comes with a 2.67x higher thermal design power.

For users who need rasterization, display output, or a conventional graphics card feature set, the LX 7G100 is the only viable option in this comparison. It has 4x DisplayPort 1.4a outputs, 96 ROPs, and a pixel rate of 192.0 GPixel/s, none of which the MI300 offers. The LX 7G100 also wins in FP16 throughput at 49.15 TFLOPS versus 47.87 TFLOPS, assuming the 2:1 rate is applicable.

The production status also differs: the LX 7G100 is listed as Active, while the MI300 has no production status recorded. The release dates place the MI300 in January 2023 and the LX 7G100 in June 2026, so the Lisuan part is the newer product. Neither part has a launch MSRP recorded in the database.

Specification Differences

The two accelerators differ across nearly every major specification field. The MI300 is built by AMD, uses the Aqua Vanjaram chip, and is based on CDNA 3.0 architecture. The LX 7G100 uses the 7G106 chip and TrueGPU architecture, with the manufacturer listed as Unknown. The MI300 comes from the Instinct (MIx) generation, while the LX 7G100 comes from the 7G100 generation.

Process nodes differ: the MI300 is on a 5 nm node, the LX 7G100 on a 6 nm node, both from TSMC. The MI300 has 153,000 million transistors on a 1017 mm² die, with a transistor density of 150.4M per mm². The LX 7G100 has unknown transistor count, die size, and density values.

Clock specifications show the MI300 with a 1000 MHz base and 1700 MHz boost, while the LX 7G100 has no base or boost clocks listed. Memory clock differs: 1300 MHz with 5.2 Gbps effective for the MI300 versus 2250 MHz with 18 Gbps effective for the LX 7G100.

Memory configuration is starkly different. The MI300 has 128 GB of HBM3, an 8192-bit bus, and 5.32 TB/s bandwidth. The LX 7G100 has 12 GB of GDDR6, a 192-bit bus, and 432.0 GB/s bandwidth. Shading units are 14080 for the MI300 versus 6144 for the LX 7G100. TMUs are 880 versus 192. ROPs are 0 versus 96.

Pixel rate is 0 MPixel/s for the MI300 and 192.0 GPixel/s for the LX 7G100. Texture rate is 1,496.0 GTexel/s versus 384.0 GTexel/s. FP32 is 47.87 TFLOPS versus 24.58 TFLOPS. FP16 is 47.87 TFLOPS at 1:1 versus 49.15 TFLOPS at 2:1.

TDP is 600 W for the MI300 and 225 W for the LX 7G100. The MI300 uses 2x 8-pin power connectors and a suggested 1000 W power supply, while the LX 7G100 uses 1x 8-pin and a suggested 550 W supply. The MI300 is PCIe 5.0 x16; the LX 7G100 is PCIe 4.0 x16. The MI300 has no display outputs; the LX 7G100 has 4x DisplayPort 1.4a.

The MI300 lists no slot width, while the LX 7G100 is dual-slot. Dimensions differ: the MI300 measures 267 mm by 111 mm, while the LX 7G100 measures 294 mm by 120 mm by 49 mm. Release dates are January 2023 for the MI300 and June 2026 for the LX 7G100. The LX 7G100 has an Active production status; the MI300 has none recorded.

Architecture Differences

The MI300 is built on CDNA 3.0, AMD's compute-focused architecture, while the LX 7G100 uses TrueGPU architecture, which the database lists as the design for the 7G106 chip. This architectural split explains the feature gaps: CDNA 3.0 prioritizes matrix math and memory throughput, while TrueGPU includes a full graphics pipeline with ROPs and display outputs.

The MI300 has no ROPs and no display outputs, confirming that it is not intended for rasterization or video output. Its 14080 shading units feed 880 TMUs, and the sheer number of compute units drives the 47.87 TFLOPS FP32 rate. The LX 7G100, with 6144 shading units and 192 TMUs, is a smaller design but includes 96 ROPs to handle pixel processing, which the MI300 cannot do at all.

Memory architecture reflects the divergent goals. HBM3 on the MI300 provides 5.32 TB/s across an 8192-bit bus, a configuration suited to feeding thousands of compute units with large working sets. GDDR6 on the LX 7G100, with 432.0 GB/s on a 192-bit bus, is a more conventional graphics memory setup, adequate for frame buffers but not for massive compute arrays.

The FP16 implementation also differs. The MI300 lists FP16 at 47.87 TFLOPS with a 1:1 ratio to FP32, meaning it processes half-precision at the same rate as single-precision. The LX 7G100 lists FP16 at 49.15 TFLOPS with a 2:1 ratio, meaning it doubles half-precision throughput relative to its FP32 rate. This indicates different design trade-offs: the MI300 treats FP16 as a first-class citizen at parity, while the LX 7G100 optimizes for accelerated half-precision workloads.

API support is another architectural differentiator. The MI300 has no DirectX, OpenGL, or Vulkan support recorded. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, making it a full-featured graphics device. The MI300's lack of graphics APIs aligns with its compute-only positioning.

Process technology differs by one node generation: 5 nm for the MI300 versus 6 nm for the LX 7G100, both fabricated by TSMC. The MI300 integrates 153,000 million transistors on a 1017 mm² die, yielding a density of 150.4M per mm². The LX 7G100's transistor count and die size are unknown, so a density comparison cannot be made from the recorded data.

The bus interface also differs: PCIe 5.0 x16 on the MI300 versus PCIe 4.0 x16 on the LX 7G100. The newer PCIe 5.0 standard on the AMD part offers higher host transfer bandwidth, which matters for data movement in compute workloads. The LX 7G100's PCIe 4.0 connection is adequate for graphics workloads but lower in peak host throughput.

Power delivery architecture reflects the performance gap. The MI300 draws 600 W through two 8-pin connectors, while the LX 7G100 draws 225 W through a single 8-pin connector. The suggested power supply ratings are 1000 W and 550 W respectively. The MI300's higher power envelope supports its larger compute and memory arrays, while the LX 7G100 operates in a lower power class.
