Summary: able to be run at fraction of the cost and lower heat into workspace than previous machine.
Pros: Great processor, very low( <40w) power for average workstation use. excellent performance when needed with turbo boost.
Cons: Supplied cooling has unacceptably poor thermal interface material. Was having various slowdowns and other issues and it turned out by testing with intel extreme tuning utility, the cpu was thermal throttling under load. Once thermal interface material was replaced, full load testing could not get...
Summary: It's a pretty good CPU for the $. There isn't as much bang for the buck as in previous cycles (in fact, SSDs have been the most efficient upgrade route for some time now), but going from an i3 to an i7 is worth it in this specific case.
Summary: I bought the 3.1 GHz i7-4770S to run 24/7 at 100% load on all 4 cores doing World Community Grid number crunching. Before purchasing, I had read several sources saying the Turbo Boost clock speed is 3.9 GHz. However, it turns out that is ONLY true when ONE core is turbo boosted.
Pros: This processor is amazingly good, and it's not even the real thing (K). I would not have minded paying the extra 30$ for the K one, but I never overclock my gear so I don't really need it. The S version is still a BOMB. I have absolutely no regret about buying this over a 4th gen i5.
Summary: I purchase this specific model of processor (i7-4770S) but I received another model instead (i5-4570S) I don't live in US and I just realized that when I was upgrading my PC. It's a bad thing that I received the wrong product, but at least Amazon gave me a refund of the difference between these two...
Summary: I think this CPU is good. But I can clearly review 10 years later. Next 2-3 years we may see changes of Computer style. I'm not sure how much we stick with desktop PC at home. I think this CPU can accept future OS ten years later.
