LEGACY SERIES VS NEW SERIES
Intel's new core ultra series has the the new introduced architecture Meteor Lake. This architecture is particularly designed for power efficiency and AI capability. The ultra series has GPU cores which are even though not powerful as dedicated graphics card, it is capable to handling most of the aaa gaming in 1080p. The NPU core in ULTRA series gives the best AI performance and features.
Where the LEGACY Intel core i series are great at consumer usage. Basically can handle the AI tasks, but as fast and efficient as ULTRA series. But the when it comes to power efficiency, the ULTRA series outperforms due to the best power efficiency cores in it.
I choose the Intel Ultra series due to its best NPU and power efficiency cores.
