3.1 GHz Kaby Lake Processor Upgrade Worth it?

Anybody thinks this will make a significant difference?

I generally don't think they are worth the cost and opted not to get the upgrade last year. An extra $200 on a ~$3k laptop isn't too crazy, but for me it was and still would be a no. GPU's typically depreciate faster than the CPU's.

Definetely not worth it.

if you are going to keep it for a while then maybe it is

Compared to what?

Usually u gain 5-10% processing power. So depending on ur use case this will help for rendering or video decoding.
But not for surfing or office 😉

Do you mean the 2.9 GHz one Vs the 3.1 or just in general?

If the former and its 2.9 vs 3.1 you mean then no...probably not.

guys, how about 2.8 vs 2.9?

I am not super educated on this, but there may be a bigger difference going from 2.8 to 2.9 because there is a jump from 6MB L3 cache to an 8MB L3 cache with that upgrade. 2.8 (7700HQ) to 2.9 (7820HQ) is not simply a clock-speed upgrade. Going to the 3.1 (7920HQ) is a clock-speed only boost I believe, so probably not as valuable.

The 2.9 will be faster by 0.1GHz

The 2.9 will be faster by 0.1GHz

Plus an upgrade from 6MB to 8MB L3 cache, which can be beneficial in some workloads.

I am also thinking about the bigger cache benefit. I wonder if 2.9 (7820HQ) will sap more energy and release more heat than 2.8 (7700HQ)?
