is Sandy Bridge still the one too get?

seeing as Ivy-Bridge and Haswell both use crap thermal paste and use 3D transistor tech, both of which increase the temprature dramatically and means poorer overclocking - i was looking at another website other day and notice the Sandy-Bridge 2500K was over £250...!!! it was once circa £156 like other i5's , now they seem to be charging more and I think its because they know they are cooler and more overclockable (5Ghz on Air) than IB or HW which your lucky to get 4.4Ghz on Air cooling..

from what ive read theres only a 2-5% of 'real world' performance gains between the three architectures ? ...is this right..?

whats your take on this~?
 
Well the new cpus have better IMC, better onboard GPU, Sandy-Bridge doesn't support PCI-E 3.0.

If you are going to buy now... you should go for the newest one for sure...

My 3770k is running at 4.5ghz since day 1, I had an 2600k running at 4.5ghz as well and the temperatures were about the same, the Ivy is a little bit hotter, but not by much.. around 2C more

my mate has the i5 4670k and I have the 2600k.
He has a 7950 and I have a 7970.
he has 16gb of vengeance I have 16gb of avexir mpower
he has the msi gaming mobo (the one with the red dragon) I have the z77 msi mpower
he is on water im on h80i and air.
we are both overclocked at 4.2ghz with stock gpu clocks

and guess what, no massive difference, its tit for tat, no clear winner, I will be sticking with my cpu for the foreseeable.

hope that helps.
 
thanks for the replies guys

Ivy-Bridge supports PCIE 3.0

@ Wazza - but according to Toms Hardware and other websites the Haswell CPU's dont overclock anywhere near as good as SB and also IB and they recommend the Ivy-Bridge Core-i5 3470K for gamers

what would be beneficial (performance wise in games) to get Haswell over Ivy-Bridge?
 
clock for clock they are 600mhz faster than sb,so 4.2ghz on haswell will equal 4.8ghz on sandy

0% unless your running more than two gpu's and do a lot of video editing/rendering(ivy-e over haswell I mean)

you mean Haswell is the equivelant of 600Mhz faster than SB...? - thats a lot more than other sites seem to suggest? thats almost 20% performance increase? Im reading on various websites that its not that much?, where did you get that figure from if you dont mind me asking?

im asking all this as a friend has asked me to price up a gaming build, i said IB core-i5 would be better as thats what TH says (more overclock potential than Haswell)
 
if buying new then get the latest tech, if you are buying second hand which isnt a bad idea, then a sandybridge or ivybrdige setup will be a good buy.

Im running a sandybridge i5 and it is certainly not holding me back running at a nice 4.5ghz
 
Not sure on the percentages,but from the gflops in ibt and the new linx stress tests,my ivy clocked at 4.8ghz was kicking out 121 gflops,a haswell chip clocked to just 4.5ghz was putting out nearly 200gflops
In linx

On average ivy is 300mhz better than sandy,and haswell again is roughly 300mhz better than ivy,I don't know how much it filters down to gaming,but processing power its more efficient

well according to CPUBOSS the 2600K overclocks 15% better (5.1Ghz) on Air than 4770K (4.5Ghz) - they test them and overall scores (at stock speeds) are:

4770k = 9.1 / 10
2600K = 8.5 /10

remember, the 4770K is 100Mhz (3%) faster at stock so if the 2600K was running at 3.5Ghz like the 4770K then the score should be 3% higher for the 2600K, this brings it up to 8.75/10 when running at clock-for-clock speeds...

if you add on this 15% better overclock margin too (just at the stock speeds scores above) you get a score of 9.77 for the 2600K which is much better than the 4770K's 9.1 - remember this is the better overclock margin only... so the 4770K doesnt get anything added on - so it appears that the Sandy-Bridge 2600K (or SB chips in general) can be pushed further than 4770K (or Haswell chips in general) in terms of performance due too the better overlock headroom - newer intel chips run too hot and dont have the extra performance enough to beat Sandy-bridge when she's running at her best overclock speeds versus IB/HW at theirs...
 
i suspect that you wont be clocking your cpu to extreme speeds so why are you worried about overclock potential? you wont be held back in terms of performance by getting a newer chip? its not all about the megaherts.

if you want megahertz then get a 9590 from amd and then you will realise its not as good as a sandybridge at like 4.5

buy new get z87 buy second hand get z77 board and either 2500k/2600k or 3570/3770k

if you really wanna overclock get a 4570k or 4770k and de-lid
 
You don't need to clock haswell as high as sandy,its faster out if the box

In any case,sandy/ivy/haswell you be hard pushed to clock past 4.5ghz unless you get a golden chip or delid it

So if buying new parts go haswell,if your coming from sandy/ivy I see no point
 
Surely the logical answer is to treat them as roughly equivalent, and buy whichever is the best value without requiring you to change other hardware to more expensive bits to match it.

I'd be a bit worried a stock 7950 matches a stock 7970 if i were you.

Like i said its tit for tat, using fraps while playing the same games there is never much in it, nothing you can notice. Real world performance, to the naked eye anyway. Sure i get a better score on mark3d11 but thats not what our pcs are for are they lol
