![]() ![]() The current ThinkPad lineup alone shows massive differences, as we have seen in this article. We have already tested numerous devices and there can be big differences when it comes to the performance utilization. However, this also results in higher power consumption and higher temperatures. They offer four native CPU cores and are much faster compared to the old dual-cores. In my experience, unless you really need a new feature, an older i7 ULV is a far better choice.Basically, every new ultrabook or laptop released since last autumn is equipped with Intel's new 8th Gen ULV-processors. However, there is a ~1-3hr average usage gain from the 3667U which is certainly a boost. I don't notice any power/efficiency difference between the 5300U-6200U, absolutely none, which was disappointing. 2.5GHz/3.2GHz it is sustaining with ease and it sustains 2.9GHz all cores when I benchmark it (under stock TDPs) which makes it perform ahead of the other two. ![]() In IXTU, I set most of them to 15W/25W, but the i7 can be clocked much higher than base, and even TDPs for when you need. The i7 clocks higher and stays there longer if I restrict the TDPs, which is what first alarmed me since it makes it perform better in the end. They have the approx same perf and user experience, except when the graphics get concerned. Except where new features/graphics are concerned. A higher end 2-3 year old CPU will normally perform just as good, and clock better and be far cheaper. Users are getting duped to buy a new model just for the sake of it being new. Click to expand.I'd agree with you from experience.
