What is Coffee Lake Refresh, and how it influenced Apple computers

In October 2018, Intel introduced the Coffee Lake Refresh (CFL-R), the ninth generation of the Core architecture. From CFL-R is different from the previous generation CFL, but they are few and none of them can be called a breakthrough. We can not say a few words on the topic “Intel is not the same”. For several generations the architecture of the processors does not change. In fact, Coffee Lake Refresh – this is the third update, it is terrible to say, Skylake. The technological process is the same as the Coffee Lake eighth generation. Intel’s move to intermediate, as they called it in 2015, technology 10 nm – but it’s still not happening. And about 7 nm Intel hasn’t said. They are now not okay, they are experiencing hard times in its history – it is a fact, but enough about that. Not the best of times, sooner or later, one way or another – come to an end.

The latest Intel processors used in Apple computers

So, Coffee Lake Refresh. In their numerical indices in the beginning of the prestigious and respectable figure “9”. For example, i9-9900KF or i3-9100T. In the current environment is the bread. October 9, 2018 in new York, hosted Intel Desktop Launch Event. As the name of the event, it was dedicated to desktop computers. The star of this event was the Intel Core i9 9900K, the most powerful gaming CPU in the world, world record holder for overclocking. Introduced some more desktop processors generation 9, but he was the center of attention. Other topics – Intel Xeon W-3175X, and what should be the desktop computer for professionals and admirers resource-hungry games. Six months later, Intel introduced processors CFL-R for laptops and added a few more desktop.

Intel has fallen out of love with Hyperthreading? At Coffee Lake Refresh this functionality leaving only the Core i9. In all other CPUs number of threads of control equals the number of physical cores. According to the statement of Intel, in some modes of the kernel can squeeze 15-20% more performance. But in all Core i3, at one time deprived of the function Turbo Boost, she now realized. All chips (except Core i3) is able to work with 128 Gigabytes of RAM (DDR4-2666), Core i3 works with DDR4-2400 size up to 64 Gigabytes. The alphabetic index at the end of the designation of a processor indicates the features of its implementation. The letter “K” reports that the processor is allowed overclocking of the clock frequency (overclocking), the letter “T” on a processor with a reduced clock frequency and a reduced TDP (design requirements for heatsink), processor without the letter in the designation can be called normal or standard, the letter “F” indicates the absence of the integrated graphics processor.

All processors Coffee Lake Refresh, if none of this letters, it switches to the Intel Graphics UHD 630. Compared to Coffee Lake 8 generation, the graphics subsystem has not changed. Chips without the integrated graphics are exactly the same as are their counterparts with it. The price is not affected. Since the onboard graphics it is easy to turn off, which is very often a special meaning in these choices. To be honest, I do not fully understand the meaning of this variation. Combinations of letters, such as “KF” to indicate the presence of both features, in this case “capable of overclocking, no iGPU”.

At the Core i9 8 physical cores, which thanks to Hyperthreading appear in the world and the computer’s operating system as 16 virtual. All of them, as we mentioned above, Hyperthreading is not supported, the system sees exactly as many cores how many of them actually. In all their 8 Core i7, Core i5 – 6, Core i3 – 4. The cache of the third level have a Core i9 – 16 MB, Core i7 – 12, Core i5 – 9, and Core i3 versions with different digital symbols they are different. Have i3-9100 with any letters at the end denote the cache third level 6 MB, all the other Core i3 – 8.

The Intel 9th generation

Intel calls these processors “mobile”. Hyperthreading and Turbo Boost are implemented in all mobile processors generation Coffee Lake Refresh. The mobile processors of its letter “H”. They differ from the table colleagues constructive requirements heatsink (TDP), the mobile processors, the 9th generation is 45 Watts. All processors, except to enable the overclocking, support mode with reduced clock frequency and TDP (35 Watts). Such processors are identified by a combination of “HK” at the end. Processors without integrated graphics are indicated by the combination of letters “HF”. Other combinations of letters in the name to Coffee Lake Refresh is not used. Schedule is the same as desktop processors of this generation – Intel UHD Graphics 630.

Mobile Core i9 in the same 8 physical and 16 virtual cores in their desktop variants. In Core i7 6 physical and 12 virtual Core i5 in their 4 and 8. The size of the cache in the third level in the Core i9 16 MB In the Core i7 – 12 and Core i5 – 8. 8-th generation someone of the experts wrote that i9 – a marketing gimmick. Intel renamed i7 to i9, i5 and i7 i3 i5. He had a reason for that, don’t you think?
