Nobody expected that during the last conference of Microsoft in addition to bankers such as new smartphones Lumia Windows 10 and tablet Surface Pro 4 will present its first laptop Surface Book characterized by a hybrid construction (rotated 360 degrees touch screen, the ability to remove the keyboard) . It is interesting to budding computer that according assurances to be “twice as fast” from the comparable MacBook from Apple. Is it actually possible, if we are here only to deal with purely marketing was played? Checking this is unfortunately not easy, because we do not know exactly which components can be found in the Surface Book ®. Based on the available information and declarations Microsoft can, however, attempt to carry out an investigation into the matter.
start an investigation
“The addition of a discrete GPU and two additional processors essentially makes the Surface Book is two times faster than the MacBook Pro” – said the vice president of Microsoft’s Panos Panay.

What did he mean by “two additional processors” ? Of course, there can be no certainty here. Perhaps he meant quad-core processor. MacBooks use because of dual-core processors with integrated graphics Broadwell. In the case of the MacBook Pro 13 we Broadwell dual-core processor and integrated graphics HD 6100. In a standard configuration get cheaper models available Core i5 chips that option could be replaced by Core i7 processor with a faster graphics.
This page allows Microsoft to explore the possibilities of Surface Booka and to order the pre-premiere, unfortunately, it has been prepared so that it is even more mysterious than a page from Apple. We are told merely that we have the opportunity to choose between systems Core 6th generation (Skylake): Core i5 and Core i7 processors.
Fortunately, given there are also other information such as that the cheapest version of the Surface Booka offers Skylake system equipped with a Core i5 Intel graphics 520. Probably in terms of systems so here Core i5-6200U and Core i5-6300U that the only offer mentioned GPU. It also means further that the declaration Microsoft’s doubled capacity does not apply to the Surface Pro in the basic version configuration.
Skylake is better but …
The latest processors Skylake are better than chips Broadwell. However, looking at their performance in desktop versions say that the mobile version is twice as fast there is no basis. It must be remembered that Skylake systems carry with them a number of other improvements (more on this later).
A little confusion here also introduces the use of Microsoft terms “faster”. This is a similar trick to that used by Apple, which in the case of iPad Pro ensures that “is about 80% faster than other portable computers” .
In addition to the Core i5 Surface Book also it offers the opportunity to take advantage of the Core i7 systems. Of course not known what exactly the model about. Probably Microsoft’s statement, however, just refer to it. If we assume at this stage that we are dealing with a unit with four cores Microsoft might decide to use one of the following three processors:
– Intel Core i7-6920HQ (8M Cache, 3.80 GHz )
– Intel Core i7-6820HK (8M Cache, 3.60 GHz)
– Intel Core i7-6700HQ (6M Cache, 3.50 GHz)
The problem, however, is that for each of them there is a TDP 45, which is incomparably more power consumption and heat generation than in the case of dual systems. Dealing with it in such a slim design, which is characterized by the Surface Book is really a big challenge. Perhaps, then, Microsoft has put on recently premiered with an Intel Core i7-6822EQ (8M Cache, 2.80 GHz) with TDP of 25 W. This is much less, but still much more than the dual-core models.
Given the above, conceivably, it seems that Microsoft has decided, however, to use, like Apple, with only dual-core processors. But in this case he could talk about double the speed? Yes and no. It all depends on what will be tested and after that benchmarks to reach.
