From the performance point of view, the Tianguet 8100 is better.
The Tianguet 8100 uses TSMC's 5nm process and uses an octa-core CPU architecture design: Four 2.85GHz ARM Cortex-A78 cores and four ARMCortex-A55 energy efficient cores, powered by ARMMali-G610 six-core Gpus, according to the blogger @Digital Chat site, The Mediatek Skyguet 8100 engineering machine is basically the Snapdragon 865 power consumption running out of the performance of the Snapdragon 888, the TSMC N5 4 4 architecture is stable, and the game continues to perform even better than the flagship core of 1 3 4.
Kirin 9000L 5G uses 1*3.13GHz A77 2*2.54GHz A77 3*2.05GHz A55, supplemented by Mali-G78 MP22 GPU, the processor is less than Kirin 9000 2 GPU, 1 large NPU. There are also two less cpus, into a six-core processor, there is no Kirin 9000L test data message, but 9000L is six core, Tianguet 8100 is 8 core, theoretically Tianguet 8100 should be stronger than Kirin 9000L.
