Intel Haswell (Core i5 4670K & i7 4790K) versus Ryzen & Coffee Lake: worth upgrading?

Is your Haswell build ready for an upgrade? 86 tests provide the answer!



Many Hardware.Info readers are probably still using an Intel processor from the Haswell generation, such as a Core i5 4670K or 4690K, or a Core i7 4770K and 4790K. 2017 was a year of unprecedented competitiveness on the processor market. Is an upgrade to AMD Ryzen or Intel Coffee Lake worth it, or should you stick with Haswell?

The video card is usually the most popular PC component to upgrade. With all these high-res monitors and increasingly beautiful games, this part is subject to higher demands at a rapid pace. After two or three years a new video card means a serious upgrade in graphics capabilities, while the rest of your system can often last for a few years.

Partly thanks to the AMD Ryzen CPUs, you suddenly get a lot more processor for your money.

At the beginning of this year, however, AMD turned the processor market upside down with the Ryzen cpu and in October, Intel followed with its Coffee Lake models. At the bottom of the line, you get much more value for your money when you buy a processor now than, for example, one year ago. So in our upgrade poll of mid-September, the Dutch readers massively indicated that they planned to have a new processor and a new motherboard - with 32% of the votes, that option was even more popular than a new video card (27%)!

We put two of the most popular processors from the Haswell generation through our current test procedure to find out whether such a fast Ryzen or Coffee Lake is worthwhile. For this we selected the Core i5 4670K, a quadcore without HyperThreading, and the Core i7 4790K, a slightly higher clocked model with HyperThreading.
