Hi all

I've been comparing a couple of CPU's from Intel and AMD and noticed that AMD use a 7nm technology and Intel 14nm..

Whats the key difference? I know temps are usually lower but is it by much or very minimal?

Cheers

intel 14nm is better than amd 14nm. so cant really compare the 2 since parts of the process are not actually 14nm or 7nm.

going from 14nm to 7nm is reduced die size for same chip and lower voltage so less heat and power consumption but depending on design since die is smaller heat density could get higher.

Hi,

TSMC' N7 class processes are much denser which allows AMD to make chips with much more transistors with better characteristics. You can start reading details from there:

7 nm process - Wikipedia


14 nm process - Wikipedia

Thanks, So is it a major difference to look for when buying a CPU?

Cheers for this i shall have a read through that wiki page and watch some youtube videos

Not really. Comparing nm of different cpus is utterly pointless as there is not standard between them. It's up to each company to define what they measure and how and then throw a number out. There is a good video of der8auer that goes into depth with this.

A Zen 3 laptop APU with 45 watt TDP (TSMC N7) will be as fast as Intel's 200+-watt Core i9-10900K (14nm).

PassMark:
Ryzen 7 4800HS - 19,044 marks (100%);
Ryzen 9 4900H 45-watt - 19,064 marks (100%);
Core i9-10900K 200+-watt - 24,110 marks (126%).

PassMark - AMD Ryzen 9 4900H - Price performance comparison (cpubenchmark.net)
PassMark - Intel Core i9-10900K @ 3.70GHz - Price performance comparison (cpubenchmark.net)

Geekbench:
Ryzen 7 4800HS 45-watt - 6,755 points (100%);
Ryzen 9 5900HX 45-watt - 9,015 points (133%);

OK cheers for the help all of you, I now know its not something to look out for I can concentrate on the other parts of a CPU that really matter

Exactly what parts of a cpu are you concentrating on now? The pin count? The colour? The weight?

Give us a budget you want us to work with and we can get some potential builds specced up.

:p I do like to count the pins to make sure they're all there, if there's 1 missing then I get a full refund...

I have a budget of upto £200 and have a Z490 Board... I just wandered if the NM was a factor to take on board so I could see if I was better going back to AMD

If you already got the intel board then newer faster CPU for that board may be cheaper than jumping ship to amd with cost of cpu and mobo

Yeah i am going to scout around and hopefully get a used 10600

Ryzen 5 3600 is still faster.

Funny, how did you end having an Z490 board? Is it new unused or used?
Sell it and jump to something like this lol:

My basket at Overclockers UK:
Total: £319.48 (includes shipping: £10.50)

I sold that exact board and thought i'd try Intel without doing much research :p Think i may have to go back to AMD and learn from this :p My current Intel z490 board is about a week old if that
