Where Each One Wins

The AMD Instinct MI350X wins decisively in raw compute throughput. Its FP32 performance of 72.09 TFLOPS dwarfs the Lisuan Tech LX 7G100's 24.58 TFLOPS, giving it a 2.93x advantage in single-precision workloads. The MI350X also leads in texture processing, delivering 2,252.8 GTexel/s compared to 384.0 GTexel/s on the LX 7G100, a ratio of roughly 5.9 to 1. Memory capacity and bandwidth follow the same pattern: the MI350X offers 288 GB versus 12 GB, and 8.19 TB/s versus 432.0 GB/s. This makes the MI350X the clear choice for large-scale AI training, scientific simulations, and any workload that saturates memory bandwidth.

The Lisuan Tech LX 7G100 wins in areas tied to its more conventional desktop GPU design. It has a working pixel rate of 192.0 GPixel/s, while the MI350X is listed at 0 MPixel/s, meaning the MI350X has no rasterization output stage for traditional display rendering. The LX 7G100 also provides 4x DisplayPort 1.4a outputs for direct display connectivity, whereas the MI350X has no outputs at all. Additionally, the LX 7G100 supports modern graphics APIs including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, while the MI350X reports N/A for all three. For gaming, desktop rendering, or any interactive graphics workload, the LX 7G100 is the only one of the two that functions in that role.

The LX 7G100 also wins on power efficiency per watt. Its FP32 throughput of 24.58 TFLOPS at a 225 W TDP yields roughly 0.109 TFLOPS per watt. The MI350X delivers 72.09 TFLOPS at 1000 W, about 0.072 TFLOPS per watt. The LX 7G100 is approximately 51% more efficient in this metric, making it the better choice where power draw and cooling constraints matter.

Architecture Differences

The AMD Instinct MI350X is built on CDNA 4.0 architecture, a compute-optimized design that omits traditional graphics output stages. Its chip, designated MI350 256CU, uses a 3 nm process at TSMC, packing 185,000 million transistors into a 2380 mm² die, resulting in a transistor density of 77.7M per mm². The architecture is part of the Instinct (MIx) generation, succeeding Radeon Instinct. It has 16,384 shading units and 1,024 TMUs, but no ROPs, which explains its 0 MPixel/s pixel rate. The MI350X features 288 GB of HBM3e memory on an 8192-bit bus, with a memory clock of 2000 MHz and 8 Gbps effective speed. Its FP16 performance matches FP32 at 72.09 TFLOPS, indicating a 1:1 ratio that prioritizes compute consistency. The card uses an OAM Module form factor with PCIe 5.0 x16 bus interface and has no display outputs.

The Lisuan Tech LX 7G100 uses the TrueGPU architecture, a naming scheme that suggests a focus on general-purpose graphics as well as compute. The 7G106 chip is manufactured on a 6 nm process at TSMC, with transistor count and die size listed as unknown. It has 6,144 shading units, 192 TMUs, and 96 ROPs, giving it a functional 192.0 GPixel/s pixel rate. The memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, with a memory clock of 2250 MHz and 18 Gbps effective speed. Its FP16 performance of 49.15 TFLOPS is double its FP32 figure of 24.58 TFLOPS, indicating a 2:1 ratio common in consumer-oriented GPUs. The card is a dual-slot design with a PCIe 4.0 x16 interface, includes 4x DisplayPort 1.4a outputs, and reports production status as active.

The architectural divergence is stark. CDNA 4.0 strips out display and rasterization hardware to maximize compute die area, while TrueGPU retains full graphics functionality including ROPs and API support. The MI350X's 3 nm node versus the LX 7G100's 6 nm node reflects a generational gap in manufacturing, even though both come from TSMC. The MI350X's 1:1 FP16/FP32 ratio suggests a design where both precisions are equally important, whereas the LX 7G100's 2:1 ratio indicates FP16 is treated as a throughput multiplier.

Specification Differences

The recorded data shows differences across nearly every major specification field. The process node differs: 3 nm for the MI350X, 6 nm for the LX 7G100. Transistor count is 185,000 million for the MI350X, while the LX 7G100's count is unknown. Die size is 2380 mm² for the MI350X, also unknown for the LX 7G100. Transistor density is 77.7M / mm² for the MI350X, null for the LX 7G100.

Release dates are 2025-06-11 for the MI350X and 2026-06-17 for the LX 7G100. The MI350X has a predecessor (Radeon Instinct), while the LX 7G100 has none. The LX 7G100 has an active production status; the MI350X has none listed.

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries, and the wins counters show zero for both cards. The percentile ranking versus all GPUs is identical at 50 for each, and the average benchmark score is 0 for both. This lack of measured data means the comparison must rely on the specification sheet alone.

From the spec data, the largest win for the AMD Instinct MI350X is in FP32 compute. At 72.09 TFLOPS, it is 47.51 TFLOPS ahead of the LX 7G100's 24.58 TFLOPS, which is a 2.93x advantage. Texture rate shows an even larger ratio: 2,252.8 GTexel/s versus 384.0 GTexel/s, a 5.87x lead. Memory bandwidth is the most extreme difference: 8.19 TB/s versus 432.0 GB/s, a factor of 18.96. Memory capacity is 24 times larger on the MI350X (288 GB versus 12 GB). Shading units are 2.67 times higher (16,384 versus 6,144), and TMUs are 5.33 times higher (1,024 versus 192).

The Lisuan Tech LX 7G100's biggest wins come from features the MI350X lacks entirely. Pixel rate is 192.0 GPixel/s on the LX 7G100 versus 0 MPixel/s on the MI350X, an infinite advantage in that metric. The LX 7G100 has 96 ROPs versus zero. It offers 4 display outputs versus none. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3, while the MI350X reports N/A for each. In FP16, the LX 7G100 delivers 49.15 TFLOPS, which is 2.0 times its own FP32 output; the MI350X holds FP16 at parity with FP32. The LX 7G100 also has a higher memory clock at 2250 MHz versus 2000 MHz, though the effective bandwidth comparison strongly favors the MI350X.

Power efficiency is a notable win for the LX 7G100. At 225 W TDP, it produces 24.58 TFLOPS, yielding roughly 109 GFLOPS per watt. The MI350X at 1000 W produces 72.09 TFLOPS, about 72 GFLOPS per watt. The LX 7G100 is approximately 51% more efficient in FP32 per watt.

The Verdict

The data separates these two cards into different product categories. The AMD Instinct MI350X is a compute accelerator with no display output, no rasterization pipeline, and no consumer graphics API support. Its 288 GB of HBM3e memory with 8.19 TB/s bandwidth, combined with 72.09 TFLOPS of FP32 throughput, positions it for large-scale AI training, scientific computing, and data center workloads where memory capacity and bandwidth dominate. The 1000 W TDP and OAM Module form factor confirm this is a server-class component, not a desktop part. The 3 nm process and 185,000 million transistors on a 2380 mm² die indicate a design where compute density is the sole priority.

The Lisuan Tech LX 7G100 is a conventional desktop GPU in the traditional sense. It has display outputs, a working pixel rate, 96 ROPs, and full API support including DirectX 12 Ultimate and Vulkan 1.3. Its 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are typical for a mid-range consumer card. The 225 W TDP, dual-slot design, and single 8-pin power connector fit standard desktop power supplies and cases. The 6 nm process and 6,144 shading units place it in a performance tier that can handle gaming and general graphics workloads.

For the PC builder or system integrator, the choice depends entirely on the intended use. If the task is rendering frames to a display, running graphics applications, or gaming, the MI350X cannot perform that function at all. The LX 7G100 is the only option that supports display output and graphics APIs. If the task is bulk parallel compute, such as training neural networks, processing matrix operations, or handling large datasets, the MI350X offers 2.93 times the FP32 throughput, 5.87 times the texture rate, and nearly 19 times the memory bandwidth. The LX 7G100 would be a poor fit for such workloads due to its limited 12 GB memory capacity and 432.0 GB/s bandwidth.

The absence of benchmark scores in the database means no measured performance data exists for either card. The percentile ranking of 50 for both is a placeholder, not a competitive assessment. Buyers should treat the specification sheet as the sole basis for comparison. The MI350X is the compute leader by every raw performance metric, while the LX 7G100 is the functional graphics card. Neither card competes in the other's domain.
