Q: What is the physical size difference between the two cards?

A: The LX 7G100 measures 294 mm by 120 mm by 49 mm. The MI308X does not have recorded dimensions in the database, but its OAM Module form factor differs fundamentally from the LX 7G100's dual-slot PCIe layout.

Architecture Differences

The AMD Radeon Instinct MI308X and the Lisuan Tech LX 7G100 represent two distinct design philosophies. The MI308X is built on the CDNA 3.0 architecture, a compute-focused design for data center workloads. Its chip, codenamed Aqua Vanjaram, uses a 5 nm TSMC process and packs 153,000 million transistors onto a 1017 mm² die, yielding a transistor density of 150.4 million transistors per square millimeter. The LX 7G100 uses the TrueGPU architecture with the 7G106 chip on a 6 nm TSMC process; its transistor count and die size are not recorded in the database.

The compute resources differ substantially. The MI308X contains 19,456 shading units and 1,216 texture mapping units, but has zero ROPs and a pixel rate of 0 MPixel/s, confirming its pure compute orientation with no rasterization pipeline. The LX 7G100 includes 6,144 shading units, 192 TMUs, and 96 ROPs, with a pixel rate of 192.0 GPixel/s. The LX 7G100's inclusion of ROPs and display outputs indicates a more conventional graphics-capable design, despite its TrueGPU branding.

Memory architecture reinforces the divide. The MI308X uses HBM3 with 192 GB capacity on an 8192-bit interface, achieving 10.3 TB/s bandwidth. The LX 7G100 uses GDDR6 with 12 GB on a 192-bit bus, delivering 432.0 GB/s. The MI308X memory clock is listed at 2525 MHz with 10.1 Gbps effective, while the LX 7G100 memory runs at 2250 MHz with 18 Gbps effective. The MI308X also has no base or boost clock listed beyond 1000 MHz base and 2100 MHz boost, while the LX 7G100 has no base or boost clocks recorded at all.

Interface and power delivery also differ. The MI308X uses PCIe 5.0 x16 and an OAM Module slot width, requiring no power connectors but a 1150 W suggested PSU. The LX 7G100 uses PCIe 4.0 x16, is dual-slot, and draws power from a single 8-pin connector with a 550 W suggested PSU. The MI308X has no display outputs and no API support listed, while the LX 7G100 provides 4x DisplayPort 1.4a and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

The release timeline also separates the two. The MI308X was released on 2023-12-05 and has a predecessor listed as FirePro Data Center, while the LX 7G100 is marked as Active production status with a release date of 2026-06-17 and no predecessor. The MI308X has no production status recorded.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the AMD Radeon Instinct MI308X and the Lisuan Tech LX 7G100, and neither card has individual benchmark scores or nearest rivals listed. The comparison must therefore rely on the recorded specification data.

The FP32 compute figures provide the clearest differentiation. The MI308X delivers 81.72 TFLOPS, which is 3.32 times the 24.58 TFLOPS of the LX 7G100. In FP16, the MI308X achieves 653.7 TFLOPS using an 8:1 ratio, while the LX 7G100 reaches 49.15 TFLOPS with a 2:1 ratio. The MI308X's FP16 advantage is even larger at approximately 13.3 times, though the different ratio conventions make direct comparison less straightforward.

Texture throughput shows a similar pattern. The MI308X processes 2,553.6 GTexel/s compared to 384.0 GTexel/s on the LX 7G100, a 6.65 times advantage. The LX 7G100 counters in pixel throughput, where the MI308X records 0 MPixel/s due to its lack of ROPs, while the LX 7G100 manages 192.0 GPixel/s. This is the only compute metric where the LX 7G100 has a nonzero advantage.

Memory bandwidth heavily favors the MI308X. Its 10.3 TB/s is approximately 23.8 times the 432.0 GB/s of the LX 7G100. Memory capacity favors the MI308X by an even wider margin: 192 GB versus 12 GB, a 16 times difference. The bus width difference is also extreme, with 8192 bits on the MI308X versus 192 bits on the LX 7G100.

The shading unit count of 19,456 on the MI308X is 3.17 times the 6,144 on the LX 7G100. TMU counts show a 1,216 to 192 advantage for the MI308X, a 6.33 times ratio. Only the ROP count favors the LX 7G100, with 96 versus 0.

Power efficiency can be approximated from the recorded data. The MI308X produces 81.72 TFLOPS at 750 W, which is approximately 0.109 TFLOPS per watt. The LX 7G100 produces 24.58 TFLOPS at 225 W, approximately 0.109 TFLOPS per watt as well. The two cards show nearly identical FP32 efficiency in this calculation, despite their vastly different scales.

Where Each One Wins

The AMD Radeon Instinct MI308X dominates in raw compute throughput. Its 81.72 TFLOPS FP32 performance, 653.7 TFLOPS FP16 performance, and 2,553.6 GTexel/s texture rate position it for large-scale compute workloads such as dense matrix operations and data center inference tasks. The 192 GB HBM3 memory with 10.3 TB/s bandwidth provides capacity and bandwidth that the LX 7G100 cannot approach, making the MI308X the choice for workloads requiring massive in-memory datasets or high-bandwidth streaming. The PCIe 5.0 x16 interface also provides a generational advantage over the LX 7G100's PCIe 4.0 x16.

The Lisuan Tech LX 7G100 wins in every area related to conventional graphics output. It is the only one of the two with ROPs, delivering 192.0 GPixel/s, and it provides 4x DisplayPort 1.4a outputs. Its support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3 means it can run graphics applications, while the MI308X lists no API support at all. The LX 7G100 also has a much lower power envelope at 225 W TDP with a 550 W suggested PSU, compared to 750 W and 1150 W for the MI308X.

The LX 7G100's physical design is more conventional. Its dual-slot form factor with a single 8-pin connector and recorded dimensions of 294 mm by 120 mm by 49 mm allow installation in standard workstation chassis. The MI308X uses an OAM Module form factor with no power connectors, indicating a specialized server mounting scheme.

For compute density, the MI308X is the stronger option. Its shading unit count of 19,456 and TMU count of 1,216 provide the resources needed for parallel workloads. The LX 7G100, with 6,144 shading units and 192 TMUs, is a smaller-scale design.

The two cards occupy different positions in the database. The MI308X, released in 2023, targets the data center compute segment with its CDNA 3.0 architecture and no display functionality. The LX 7G100, released in 2026 and marked as Active, targets general graphics and compute with its dual-slot design, display outputs, and full API support. Neither card has recorded benchmark scores or nearest rivals, so the specification data provides the only basis for comparison. The MI308X offers more of everything except power efficiency, display capability, and rasterization hardware.
