Kaby Lake is the eighth Intel Core CPU. With its big 7700K it should do good right? Well it does, it’s better than the previous generation i7-6700K. With the i7-6700K rating 11,111 vs 12,097 i7-7700K on Passmark. The major change is an improved 14nm process that improves clock speeds and power characteristics because of the changes in the fin and silicon, and the second change involves updates to the video/multimedia block to support hardware decoding and encoding of 4K. So you can binge Netflix in 4K! Roughly one third of the CPU die is devoted to graphics and multimedia functions.
Even though the i7-7700K is better, its better by a little percent. 4.5GHz turbo compared to 4.2GHz turbo on the i7-6700K and 4.2 base vs. 4.0 base give the expected performance differential of five to seven percent. If you overclock both processors you’re looking at 4.7GHz against 5.0GHz! Is it worth a $20 difference? With this rate of difference you’ll be hearing crickets at the Intel booth.
- Socket: LGA 1151
- Clock Speed: 4.20 GHz – 4.50 GHz
- Bus Speed: 8 GT/s DMI3
- Cores: Quad Core
- Cache: L2 – 4 x 256KB L3 – 8MB
- Threads: 8
But don’t get me wrong, the i7-7700 Kaby Lake is a great processor but there’s just no effort by Intel. I mean, it has the highest clocked Intel CPU and 5.0GHz overclocks. Who doesn’t want that? If you can fork up $350 for a CPU that only has slight differences that you probably won’t notice in a PC you’ll still have peace in mind that you have one of the best Intel 4 core processor. If you want a good all around CPU for a decent price, this isn’t the best option. But if you have the money, then go right for it. You can go home and watch 4K Netflix with your $350 i7 box.
This is the best preforming Intel CPU in the i7 line. It’s just a little depressing that it’s a quad core. But if you are looking to buy this CPU you can’t really go wrong. A lot of people seem to like the $350 quad core, because it’s rocking a sweet 5 egg on Newegg.com.
