Hello, this is a little unrelated question to this specific laptop however since the thread has some traction I'll post it here to get some answers - please ignore it if you really find it not related to the topic. Now, I see that the XPS and most similar (good) laptops in the high-end price range have processors like i5-5xxxU, i7-7xxxU (for example XPS has i7-7500U) etc. Now, these processors may be i5 or i7 but, if you take a look at their real speed you'll see that they really, really slow: https://www.cpubenchmark.net/laptop.html https://www.cpubenchmark.net/laptop.html. the i7-7500U has a benchmark of 5,306 while, the high-end laptop CPUs have around 10,000! Also, my humble 2 year old desktop i5-4690K has 7,700 (https://www.cpubenchmark.net/common_cpus.html https://www.cpubenchmark.net/common_cpus.html)! So my question and general comment is has anybody noticed it? I haven't ever seen that remark on any reviews. The XPS is considered one of the best laptops in the market. Is it really so slow? A fast CPU is required for most common (developer) tasks i.e compiling, running VMs etc. Why nobody's mentioning that slow CPU speed? I understand that the laptop manufacturers prefer these CPUs because they have better battery life but shouldn't there be an option for people that require the extra speed and don't care that much about the battery? Please notice that this isn't an issue with XPS only, for example, the Lenovo Thinkpad T560 as an even slower CPU (http://shop.lenovo.com/gb/en/laptops/thinkpad/t-series/t560/ http://shop.lenovo.com/gb/en/laptops/thinkpad/t-series/t560/). From my market research I've concluded that the only laptops that do actually have good CPUs are the gaming laptops that have i7-xxxHQ and similar CPUs. If I am not mistaken, the CPU is not as important in gaming as the GPU -- while in a developer machine CPU is no1! (along with memory size of course)

My 6 year old HP EliteBook has slightly better spec that my new HP EliteBook. The build quality is worse too, the newer one is just more lightweight and s bit thinner, but the battery is just 4h instead of 15h. I would go back to the old one, the only better thing is the screen resolution.

Simple explanation: the i5 and i7 in question are 2 core, 4 threads, compared to your desktop's i5 which is 4 cores, 4 threads.

  Kaby Lake with 4 cores is still pending https://en.wikipedia.org/wiki/Kaby_Lake#Mobile_processors https://en.wikipedia.org/wiki/Kaby_Lake#Mobile_processors

Most companies have models with more powerful CPUs, they just are not in the sleek Ultrabooks/compact devices that get most of the attention. Your "humble" i5 has 3-4 times the TDP, so it's not surprising it's a lot faster. With Lenovo, look at P-series and T460p if you want performance, but the other large manufacturers have such series as well.
