화웨이 CEO 리차드유는 A77에서 소비전력 20% 개선이 되었다는 주장과는 다르게

이미 A76 넣어도 사용자들이 요구하는 성능보다 더 뛰어남 5나노때 넣을께 ㅋ

A side note here: we had expected Huawei to launch the new Kirin with Arm’s latest A77 core, as it was announced earlier this year. Despite being a priority Arm partner member, the company’s technical team explained to us two things: firstly, the core decisions were made almost two years ago for this chip, but aside from that, they were not seeing the expected frequency from the A77 on TSMC’s 7nm processes.
Huawei stated that even though A77 hits higher peak performance, the power efficiency of the A77 and A76 on 7nm is practically identical, however due to better experience with A76 on 7nm, they were able to push the frequencies of the core much higher. It was cited that other companies with announced A77 products were only achieving 2.2 GHz on similar process technologies at other fabs. It was stated that A77 will likely come on a future product, most likely when 5nm becomes more widely available.
이런 얘기도 있더군요.
