Difference between S and non-S series I5 cpus

[Dadrian Daedalus]

Hello everyone.I am currently using a core 2 quad cpu based system.However as its rather slow i have been contemplating upgrading it (primarily for gaming).

I am getting a pretty good deal on an used i5 3570s cpu from someone i know-will it be ok to buy it?i have been told that the s series i5 cpus are designed to consume much lower power,hence their performance isn't really as good as their non s counterparts.

Will the i5 3570s be markedly inferior than the regular i5 3570?If yes,how much of a difference is there between the 2?Is the performance of i5 3570s comparable to any older i5 cpu such as i5 2500/2400?

Will it be a bad idea to buy the i5 3570s for gaming?Please advise.

(please note that my budget wont permit me to go for a newer cpu right now,so i am leaning towards buying an used cpu).

Benchmarks usually give a pretty good indication of what performance difference you'd see between 2 chips from the same architecture with different clock speeds.

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3570+%40+3.40GHz

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3570S+%40+3.10GHz

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-2500+%40+3.30GHz

In this case, hardly any difference at all, and the 3570s will be a perfectly capable gaming chip, and still a bit quicker than a 2500. If you can find a 3570, go that route; otherwise, the 3570s will do you just fine, especially with something short of a GTX 1070 in the GPU department.

Ok,thank you very much indeed for your reply.Can passmark scores be regarded as an effective way to gauge a cpu's capabilities?Can it be used as a reliable measure of a cpu's speed and efficiency?

I too was looking for a 3570 but unfortunately its not available here,therefore my choices are confined to an i3 3220 or an i5 3570s at the moment.But the latter seems like a more sensible choice if these passmark scores are anything to go by.

Somewhat. The multi-core scores should be taken with a grain of salt, but when comparing gaming capability, generally, the higher the single-thread rating, the better of a gamer a chip will be. Generally ~1900-2000 will be a capable 60 FPS gaming CPU; anything over that is gravy.

This is changing slightly as games scale more well to multiple cores/threads, but most are written these days so that they schedule on a single core, and run those jobs off to other cores to do work. These days, you generally want at least 4 physical cores - 2 real cores and 2 HT cores like an i3 are already becoming obsolete in the gaming world.

Well then i think its safe to opt for the 3570s.Today while comparing the performance of the 3570s with i5 2500k on cpuboss.com,the results indicated that 3570s doesn't support EM64T,which is supported by the latter.But its definitely not true,right?Nowadays even the most entry level cpus come with 64 bit capability.

I am referring to this page:

http://cpuboss.com/cpus/Intel-Core-i5-3570S-vs-Intel-Core-i5-2500K

I hope this is probably just an erroneous result produced by cpuboss-even the specs of the 3570s on intel's website seem to indicate that this cpu does support 64 bit computing.

Yeah, it has all the same instruction sets. Actually, I just noticed the single-core turbo speed is the same too.
