Minor performance difference over last gen.

Upgrading from the 2nd gen doesn’t look worthwhile.

Ivy Bridge Intel Core i7 3700k is the best LGA 1155 CPU, which is way better than the i7 2700k and comes at the same cost. The cores and the threads remain the same, and it also comes with four cores and eight threads and supports Intel Hyper-Threading technology, which offers excellent performance in games and other applications. The things that changed between these processors are a generation gap with more transistors, better clock rates, and performance.

Like the current generation processor, it also got a 100 MHz boost in clock speed from the last generation and provided a base clock of 3.5 GHz. It’s the best 1155 CPU in which turbo reaches up to 3.9 GHz and allows a little bit of overclocking with the stock cooler. While in reviews, we can see that the gaming performance of this processor is good enough, but we can’t expect something like what modern machines are offering us these days.

Overall, when we see it in terms of performance for modern games and applications, there is no doubt that this is the best powerful LGA 1155 CPU and what else we can expect from eight-year-old hardware. One thing to note is that the non-K version is slightly cheaper than the other one, and if you don’t consider overclocking, you are good to go with that one, but you need the K variant for overclocking. Intel Core i7 3770k comes with an Intel HD 4000 series graphics card quite good for mid-level gaming.
