Skylake 6th generation Core i5 processor...

Added 4 years ago.

Good

3 months ago.

Fairly decent for it's age considering it's almost 5 yrs old. It's very doubtful anyone would realize it's only running the clock speed at 2.7 base, with a turbo boost available to 3.3 (but actually seems to only hit 3.2) and only 4 cores/threads. To the reviewer above mentioning he is overclocking it to 4.3...not trolling, but are you absolutely sure this is the right CPU listing? A 2.7Ghz cpu with a max listed turbo boost of 3.3 getting another full 1 Ghz beyond it's max boost...1.6Ghz more than the cpu is rated at just from overclocking? Admittedly, I am far from a newb with PC's and tech, but I absolutely am when it comes to Overclocking to the limits out of fear or going to far

It's great for low end gaming, but once you start playing the higher end games, it starts failing.

Despite its age, still a cost effective processor when coupled with a right GPU


Excellent

I like it because Im using this processor while being overclocked to 4.3Ghz. Using it on a Asus Gene Viii and cooling it with a cheap Corsair Water Cooler, it is really stable, cool (39° when its 100% under load) and cheap! Perfect for gaming! Using it with a Rx Vega 56 and its not a bottleneck while on this state.

Runs games just fine to this day and doesn't really bottleneck my GTX 1070, wouldn't get it now since better alternatives exist

Not the best for the price, scam

For a relatively cheap, outdated CPU, it performs just fine.
