For those who don’t know, the Core i7 has always been the most powerful processor from Intel’s CPU line-ups. The seventh generation of Kaby Lake 7700k processors is the successor to the outgoing Skylake 7600k CPUs we saw last year. The Skylake models brought with them a bunch of very welcomed performance upgrades, higher clock speeds, improved graphics and efficiency when it comes to power and thermals. We expected the same minor improvements from the Kaby Lake series but to our dismay, the improvements were so minor that they were almost negligible.
The new Kaby Lake chips are much smaller, meaning that their individual transistors have a taller and thinner design, which means more efficiency. To put this as simply as possible, smaller chips mean more efficiency and more efficiency means more power. That is what we came to expect from the seventh generation of Intel’s core chips but the benchmarks showed us very little to be excited about.
There were some improvements in performance but they weren’t too substantial to be excited about. Anyone can overclock their older chip to outperform the newer series just by reading about it from Google and for free. The graphics capability of this chip is about the same as ever but if you’re building a PC for graphic designing or gaming, then you’d get a dedicated graphics card anyways so the Intel HD graphics don’t really mean much to you anyway.
According to iTechPost’s article, the Kaby Lake series isn’t outperforming anything Intel has made over the last two years but there are some pros to this new chip as well. It’s very easy to overclock, so beginners might be drawn towards it, for instance. But other than that, it’s not worth replacing an older core i7.
