AMD Radeon 780M vs Lisuan Tech LX MAX Comparison

AMD Radeon 780M and Lisuan Tech LX MAX occupy opposite ends of the graphics spectrum. The 780M is a 15 W integrated processor for compact systems, while the LX MAX is a 225 W dual-slot discrete card with 12 GB of dedicated GDDR6 memory. The database shows no direct head-to-head benchmark results between them, so the comparison rests on their recorded specifications and the 780M's measured scores.

Where Each One Wins

The AMD Radeon 780M wins in power efficiency and integration. Its 15 W TDP allows it to operate without power connectors, using the motherboard for display output. The LX MAX requires a 550 W suggested PSU and a 16-pin connector. The 780M also supports Vulkan 1.4, while the LX MAX lists Vulkan 1.3. For systems prioritizing low power draw and compact layouts, the 780M has the clear advantage.

The Lisuan Tech LX MAX wins on raw compute and memory bandwidth. Its 24.58 TFLOPS FP32 figure is over 2.7 times the 780M's 8.909 TFLOPS. The 432.0 GB/s memory bandwidth dwarfs the 780M's system-dependent shared memory. The LX MAX also has 12 GB of GDDR6 on a 192-bit bus, versus the 780M's system-shared memory. In any workload that stresses sustained throughput, the LX MAX leads.

The 780M shows a 61st percentile ranking among all GPUs, with an average benchmark score of 17588. The LX MAX has no recorded benchmarks, leaving its percentile at 50 with an average score of 0. The 780M's measured results include 480 in 3DMark Steel Nomad DX12, 18602 in Geekbench OpenCL, and 33683 in Geekbench Vulkan. These provide concrete data points; the LX MAX has none.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the 780M and the LX MAX. The comparison must rely on the 780M's recorded results and the LX MAX's complete lack of benchmark data.

The biggest wins for the 780M are in its measured performance relative to its power envelope. Its 8.909 TFLOPS FP32 at 15 W produces a far better performance-per-watt ratio than the LX MAX's 24.58 TFLOPS at 225 W. The 780M's 480 score in 3DMark Steel Nomad DX12 and 33683 in Geekbench Vulkan demonstrate functional capability in a 15 W package. Its 61st percentile ranking places it near the NVIDIA GeForce RTX 4060 in average score, which sits at 17639 with a -0.3% delta, and slightly above the AMD Radeon Pro 560 at 17551 with a 0.2% delta.

The LX MAX wins decisively in raw throughput. Its 192.0 GPixel/s pixel rate is over double the 780M's 92.80 GPixel/s. Its 384.0 GTexel/s texture rate is nearly 2.76 times the 780M's 139.2 GTexel/s. The 432.0 GB/s memory bandwidth is a massive advantage for large datasets, and the 12 GB GDDR6 frame buffer allows for texture-heavy workloads that system-shared memory cannot accommodate.

The 780M's nearest rivals in the database include the AMD Radeon Pro 560 at 17551 average score with a 0.2% delta, the NVIDIA GeForce RTX 4060 at 17639 with a -0.3% delta, the AMD Radeon HD 7790 at 17666 with a -0.4% delta, and the AMD Radeon Pro 460 at 17509 with a 0.5% delta. This cluster shows the 780M performing within half a percent of these discrete cards from previous generations despite its integrated nature.

The Verdict

The data presents a clear split. The AMD Radeon 780M is the choice for systems where power draw and physical footprint matter most. Its 15 W TDP, IGP slot width, and lack of power connectors make it suitable for thin laptops and compact desktops. Its measured benchmark scores, including 18602 in Geekbench OpenCL and 33683 in Geekbench Vulkan, confirm it handles modern workloads at its class level. Its 61st percentile ranking shows it outperforms many discrete GPUs from earlier generations.

The Lisuan Tech LX MAX is the choice for raw performance and dedicated memory capacity. Its 24.58 TFLOPS FP32, 432.0 GB/s bandwidth, and 12 GB GDDR6 give it a commanding lead in compute-heavy applications. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate suggest strong rasterization throughput. However, the absence of any recorded benchmarks means its real-world performance is unverified in the database.

The 780M has the advantage of verified results and proven compatibility, with Vulkan 1.4 support and a 4 nm process. The LX MAX offers superior specifications on paper but no measured scores to confirm them. Its 225 W TDP and dual-slot size require a system built around its demands. The 550 W suggested PSU and 16-pin connector indicate a desktop-only deployment.

Users needing a low-power integrated solution with known performance should select the 780M. Users needing maximum compute throughput and dedicated memory should consider the LX MAX, understanding that its benchmark data is absent. The two products serve different segments, and the database confirms no overlap in their intended use cases.
