>> One needs to know Why? you are interested first.
Partly because I want to finally get around to building my own, which I've always found vaguely intimidated so haven't done, and partly because it annoys me that I don't understand.
>> For gaming, Video card is the baby to concentrate on.
Got that. Also RAM.
>> I am using the ranking in www.cpubenchmark.net/cpu_list.php to explain the choices.
A good reference, but it doesn't really explain.
e.g.
Of the following two, apparently the i5 is better. Higher CPU mark and better rank. I am ignoring price.
Rank 1460 Intel Core i5-4200U @ 1.60GHz
Rang 1461 Intel Core i7-940XM @ 2.13GHz
So the older gen, lower i number, slower clock speed is 'better'??
I realise that the difference is probably not one that I'd ever notice, but I don't understand why.
>> There are i3, i5, i7, i9.
>> Of Note because generally performance between them varies
Right. But it seems that other factors can outweigh the i nymber.
>> Gen 1 - ?
>> OF Note, because of variances required in motherboard chip sets.
At least I understand this one and the choice is logical.
>> Speed of CPU
>> Generally unimportant,*
OK, faster is hotter. Got that. But a CPU doesn't have to run at full speed does it? Do would a faster CPU not run at a lower capacity? OR do CPUs always try to run as fast as they can?
And why isn't speed important? Bear in mind my CPU knowledge comes from 80s DEC kit, and that wasn't very complicated by comparison.
>> No. of cores
>> Generally unimportant*
If a CPU has 4 cores, does that mean that each core gets 1/4 of it's performance? Or is it that when the CPU is not running at full capacity overall it can use some of that spare capacity by doing mroe than one thing at once?
>> Threads.
>> Unless your software is developed to use them properly (Windows isn't) unimportant,
Are threads to cores as cores are to CPUs?
>> The AMD Ryzens are vastly superior in every respect as things stand.
And seemingly reasonably priced. Is there any issue from going non-Intel? There used to be potential issues a gazillion years ago.
I appreciate the effort.
