i5-4750 or i5-6400 Help with a choice, urgently.
People, I apologize for such impudence, but you have to choose quickly. What is the best percentage to take. 4570 is cheaper than 6400 and better than it. But what then is 6400 more expensive? It is worse in frequency. Tell me please. which one to take.I7 4790k.
And the 6700 is better because the new socket - there are prospects for an upgrade

Damn, wrong. Yes 4570. It's just that the order has already been made, and I urgently need to either refuse or pay.

is actually 4570 more powerful, but the new generation i5 6400 is a smaller process technology. And do not forget about the socket, it is different there.

I know. Simply, on the one hand, more GHz. (2.7 versus 3.2 GHz, but I don't use overclocking), + I have a 1 GB vidyah, so there is no point in looking at the tests on the internet. There are usually tests either with titans for 4 GB, or with a trifle for 2 GB.

What difference does it make what kind of vidyahi they have there? The main thing is that they are the same there, but the processes are different. Follow them and see what suits you best.
ordered so bite elbows,
most likely these processors will be approximately identical in performance. This is a nada benchmarks to watch the
difference, how would the platform be ddr3 and ddr4. Well, of course, newer ones that are close in characteristics and nomenclature are somewhat faster.
MoulSoul is
still architecture and other factors are influenced. As a rule, processors at the same frequencies and the same number of cores are 5-10 percent faster than the spinning model.
and so probably in this case 4xxx will be better than 6xxx

Better see for yourself

i5-6400 is more expensive than i5-4750 for the following reasons:
1) RAM: DDR4-1866 / 2133 versus DDR3-1333 / 1600
2) Bandwidth of RAM: 34.1 GB / s versus 25.6 GB / s
3) Bus speed: 8 GT / s DMI3 versus 5 GT / s DMI2
4) Max TDP: 65 W versus 84 W.
5) Process technology: 14nm versus 22nm.
In synthetic tests, both processors show the same performance (the difference is insignificant, less than 1% in general).
Thanks to the new architecture, the i5-6400 does more computations per clock cycle than the i5-4750. Therefore, its 2.7 GHz is identical to the 3.2 GHz i5-4750, that is, the i5-6400 spends less energy and heats up less when performing identical work. As you understand, the higher the frequency, the higher the temperature. The higher the temperature acts on the processor, the more machine cycles it passes. Cycles are skipped, and the efficiency and performance are reduced accordingly - this is CPU throttling.
Therefore, the i5-6400 is more stable (efficient) under prolonged loads than the i5-4750, due to the reduction in throttling.
