Hi all. I know squat about computers, below is what I have learned recently.

Time to upgrade my pc laptop for new sub-hobby to photography; video (for now, using Canon 60D and new Lumix FZ2500); would stay with pc and laptop. I would like the laptop to handle up to serious amatuer level video editing; will start out with PowerDirector software but may upgrade in the future.
Per advertising, the new intel 8th generation coffee lake processors (six core i7, i5) offer a big jump in editing speed from 7th gen processors (4 core); with minimal price increase. My budget is at $1500. I get the impression that what works for gaming also is what would work for video editing? A few questions...

-any concerns that these new 8th gen coffee lake processors are too new, may have bugs to work out? If yes, is it worth waiting until next year some time?
-should I go for the top i7 8700, or the i5 8600 which reviews seem to like better for gaming?
-some laptops come with both an HDD and SSD drive. Is that a benefit? I.e. why not just a large SSD, or HDD? And how large?
-I am thinking there will not likely be discounts on 8th generation laptops, that is ok. However if there may be discounts this year yet, when would they come out and from where?
-any recommendations on video card (specific to video editing) if there are options?
-if you were to buy a new computer, where from?
-any other advice would be appreciated.

Thanks ahead of time !!

I asked the same question. Look here at post number 5, Jake answers the question...

Oh, I forgot...Dell makes a few 8th gen laptops. You might want to check these Dell Black Friday deals...

The microprocessor companies make a big thing of the number of cores...they do not tell folks that unless an application is WRITTEN FOR MULTICORE processors, it will not take advantage of the processing power!!! A CPU with two cores, for example, could run two different processes at the same time. This speeds up your system, because your computer can do multiple things at once. But what SIX different things (or even FOUR -- at the same time) would your computer be doing, that use the multiple processors?!

While the concept of multiple core processors seems appealing, in order for the true benefits of the multiple processors to be seen, the software that is running on the computer must be written to support multithreading. Without the software supporting such a feature, threads will be primarily run through a single core thus degrading the efficiency...if it can only run on a single core in a quad core processor, it may actually be faster to run it on a dual-core processor with higher base clock speeds. All of the major current operating systems have multithreading capability, but the multithreading must also be written into the application software...and a single core can support typically two threads.

As for multiple cores, many games still have very little performance difference between two and four cores. As of today (Q4'2017) there are essentially no games that see tangible benefits from beyond four processor cores.
So if you are a gamer, and if you are running a game (that only uses two cores) while you are waiting for your RAW convertor to output 1000 JPG files on your Windows machine, you might use four cores.
Otherwise, don't become enamored of the number of cores...processor cycle rate gives you better performance for a single task.

I realize this thread is a few month old, but I just build a Coffee Lake desktop (hackintosh) and I have to say, it is a substantial jump in performance from Kaby Lake, particularly given the low cost of the cpu. Moreover, even with apps that do not use multithreading, the single core turbo is better, too. So, in my view, for overall performance I think the Coffee Lake processors are a wise investment, particularly the 6-core i7 series.


"Raw" is not an acronym, abbreviation, nor a proper noun; thus, it should not be in capital letters.
