The eighth-generation Core i series, which is known as the most complicated name in history, is not a name for itself. From ultra-low voltage to multi-core flagship, it seems that CPU has become a new problem.
Compare the meaning behind each product model to the geeks. Let's go directly to the actual battle and talk about how to choose the most common 8th generation Core.
The 15-inch notebook must be better than the 13-inch notebook? With the notebook series, the answer is certain.
13-inch notebook considerations to heat dissipation, generally use low-voltage U series, such as the Core i7-8550U on XPS 13. The 15-inch notebook has more internal space and more heat dissipation, so it will use H series processors, such as XPS 15 Core i7-8750H.
The U series will have two cores less than the H series, that is, when the U series has 4 cores and 8 threads, the H series has reached 6 cores and 12 threads.
Especially under the stimulation of AMD, The number of Intel cores has also begun to rise all the way. The quad-core and 8-thread desktop processors two or three years ago are not even as fast as a 15-inch notebook processor. This proves once again that the old users have no human rights.
Don't say it, first cry to your desktop.
I want to buy a 13-inch notebook, how to choose?
Although the more expensive the better, the hard truth. But if the most cost-effective, things are not so absolute.
Give a chestnut , Core i5-8350U and Core i7-8550U only between the frequency of 400MHz, and 2MB cache, but the actual performance of the Core i7 will have higher requirements for heat dissipation and power consumption.
If the wallet is not thick enough, there is not much problem in choosing the Core i5. After all, if the latter is not fully cooled, it will encounter a flaw that can only last for a few minutes.
The most typical example is that the performance of the Core i9 version of the MacBook Pro in the previous two days is not the same as that of the previous generation. Although Apple actively takes the pot, it still proves that the higher the specification, the higher the heat dissipation requirement, and the higher the mold design requirement.
Because the actual processing performance of the processor is not much different, the possibility of the Core i5 counterattack is born.
Chestnuts are still 13-inch MacBook Pro, the starting price of 14188 yuan even killed the Core i7 version of XPS 13, part of the reason is that the same is the eighth generation, but the performance of the core is different from the Core i5-8269U. The latter 28W power consumption makes it more powerful than the Core i7-8550U, the Turbo frequency is not only higher than 200MHz, the nuclear display is Intel Iris Plus Graphics 655, with 128MB eDRAM, let UHD family cry in the toilet.
So if you choose the CPU type of your notebook according to performance considerations, please refer to the following order:
Core i7-8559U> Core i5-8269U> Core i7-8550U> Core i5-8350U
Yes, it is so chaotic, and the first two are still exclusive to the 2018 MacBook Pro, other brands of notebooks may still need to wait for a while.
Is the difference between the limited edition and the regular edition big?
a little bit.
The controversy of this issue is actually focused on the difference between the desktop desktop processor Core i7-8700K and the Core i7-8086K 40th Anniversary Limited Edition. Essentially, the core of the two processors is the same, but the Core i7-8086K Equivalent to Intel's official special product, can achieve 5GHz core frequency.
But in fact, as long as the Core i7-8700K is selected, it can still compete with the 8086K. As for the 7GHz world record, don't think about it, relying on character and burning money.
The problem is that the gap between the two is nearly 1,000 yuan, and more than half the price of 8700K to buy a feeling, probably only fans will really do so.
Is the fusion chip powerful?
AMD and Intel jointly launched the eighth-generation Core G series including AMD Radeon RX Vega M, such as Core i7-8809G, Core i5-8305G.
Telling the truth, it's really amazing, completely let the 15-inch 2-in-1 notebook rejuvenate. This chip is equivalent to a single-processor volume that combines the independence and CPU, AMD Radeon RX Vega M can't say too strong, and GeForce GTX It's okay to compare the 1050 Ti. It's ok to know that the two-in-one notebook can play the game itself is a big improvement.
As for the choice between Core i5 and Core i7, please refer to the previous 'I want to buy a 13-inch notebook, how to choose?' Chapter, the difference between the two is not too big, AMD Radeon RX Vega M is also divided into GL only according to the power And the GH version, even so the Core i5-8305G can still be considered.
Is the Core i9 worth buying now?
It has been rumored that the Hi-end PC like the X299 platform will replace the CPU pins at least for two generations, but it feels like this legend is about to be hit. The upcoming Skylake-X, Kaby Lake-X platform may be replaced with the LGA3647. Now the LGA2066 on the X299 platform is likely to become a swan song.
That is, The current Core i9 may become one of the shortest-lived flagship processors.
So with the current computer classmates, may wish to wait. After a few months, with the cost-effective Core i9-9900K, or go straight to the more flagship LGA2066/LGA3647 is the most ideal choice. Now into i9, feel Like the current high price into the GTX 1080 Ti, it is a bit of a 49-year entry into the national army.
Written at the end: expensive is not necessarily the best
2018 MacBook Pro i9 top performance performance encounters Waterloo, a big reason is that the heat sink meets the bottleneck under high frequency. The notebook that pursues thin and chasing performance will eventually become a 'three-minute real man'. So, don't over-focus Performance, the energy consumption ratio of the mobile version of the CPU is still very important.
But if it's a desktop computer, as long as it doesn't lack money, of course, it is still the most aggressive. Under the same configuration comparison, even the retail price of Apple iMac Pro will be similar to the cost of DIY PC assembled by itself. This was born.
