Choosing a CPU - Cache or clock speed?

[Hatsjer]

My big brother is planning to build a new computer. And out of the two of us, do I have the most knowlegde when it comes to hardware. However, I am still only an apprentice. 

 

When he was going through a list of CPU's, did he ask me a good quiestion: What is the difference between cache and clock speed, and which are best when it comes to gaming? - I know know what both cache and clock speed are/is/does. (Feel free to correct my mistakes if you care enough to. Typos too.  )

 

 

 

But while I'm making this topic, did an other thing occur to me in

. 

 

Linus mentionned that not all CPU can use DDR3 RAM, as some have been designed for DDR4 RAM. - So are CPUs designed for DDR4 RAM backwards combatable to DDR3 RAM as well, or do we need to look out for that as well?

 

 

Any and every help and information is greatly appreciated.

Thanks.

More cache is better for video editing/any kind of editing really when those cores are under stress.

Core clock is just more instructions can be handled the higher it is, Core clock doesn't matter really, But when you overclock you see your self getting more FPS because the faster the clock the more info it can process before letting the GPU process the image.

A higher clock is mostly better.

 

Also, it makes no sense to go ddr3 when ddr4 is out when your CPU supports ddr4.

We have not entierly decided whenever to use DDR3 RAM or DDR4.

Thanks a lot! This is exactly what I was looking for!

I can help with the build if you want?

Or you can link it to me and I can try to make it better if you want.

All up to you!

I already have a friend who has been fidling with computers for more years than I have been alive. The only reason why I did not ask him is because he asked me not to disturb him while he's playing Fallout 4. And I respect that. 

Also, because reasons, does my brother want to keep the build to family only (Which means more or less me and him.) - But I really appreciate your offer.

Completely understandable.

DDR3 kills Skylake CPUs, because of higher voltage, Skylake supports DDR3L, which is at 1.35V instead of 1.5V(DDR3)

Also, a better CPU means less stuttering in stress situations(like many Ai in GTA 5, or many cars in Beam.NG Drive)

So, you're saying that Skylake CPUs are designed for DDR4 RAM?

Yes, Intel never stated that Skylake officially supports DDR3.

Thank You.
