What the heck is "Performance per watt 6.41 pt/W 18.35 pt/W" ??
I have used 4700MQ on my Alienware 14 notebook which is comparable to 6700HQ. The overall performance on 4 cores was better than 6700 HQ (3.2 Ghz vs 3.08 GHz) I have on new Alienware 15 laptop especially for CPU intensive C++ compilation with 6 million lines of code. I went for Alienware R2 for PCIe interface which will support ultra-fast Samsung SSD 960Pro/Evo and longer battery life 92WHr vs 69 WHr on earlier one. Unfortunately Intel has messed on 6th generation like 5th generation which I skipped. You neither get higher clock speeds nor more cores. As far power savings 2 W do not matter in real life. So my new laptop is CPU constrained.
when using all four cores the i7-4720HQ can do 1.2 GHZ better, who cares about newer architecture, the i7-4720HQ still wins vs the 6700HQ
Also the 6700HQ can clock all four cores at only 3.1 GHZ vs 3.4 GHZ of the i7-4720HQ that is significantly higher, and trust me, you can tell the difference. The i7-4720HQ is way better in every way
The i7-4720HQ is by far the faster of these two processors, I have owned both in laptops, and the speed of the i7-4720HQ is much much faster, when you open up the task-manager and watch how many GHZ it is running at, the i7-4720HQ will constantly hit 3.54 GHZ where as the 6700HQ will only max out at around 3.34 GHZ. Also the i7-4720HQ can clock 4 cores at the same time at 3.4 GHZ so I am not sure what most people are talking about as far as this is not a good multi tasker, but this thing is way faster in comparison to the 6700HQ...
>And it is better in almost everything. Nah, from the test it's clear that it's only better when it comes to integrated GPU tasks which doesn't matter much, since you are gonna use dGPU anyway. When it comes to CPU processing power it's actually worse (because of the higher max. CPU clock in 4720HQ)
it says it ALL: the bus transfer rate
Buy both and tell us which one works better :p
i dont know why but skylake went backwards in single core performance. you can see that when comparing it to haswells single core performance.
Overpriced.
whichever has better cooling and if it's the same I'd go with the 980m
so the difference is not that much. Core 6700HQ with 960m or 4720HQ with 980M? Hmm....
gururlandım it
Lan gavur kardeş, 6700hq daha yeni çıkan bir işlemci. Yeni mimari ve 14nm. Tabii ki 6700hq daha iyi. If he does not understand what I said look at the google translation. Hep biz mi google translate' e kopyala yapıştır yapacağız lan! Türkçe ingilizce karışık yazdım ki google translatede uğraş dur.
What you think of Dell XPS 15 with skylake?
So it's better to have 6700HQ in laptop than 4720HQ ? because I'm buying a laptop... :p
And it is better in almost everything. Just the single-core tasks goes faster in the 4720HQ and nowadays everyone try to distribute the load between all the cores.
This is an eye opening article. I have always thought that the 6700HQ is better.
