which chip?
 

Doing a upgarde which one is best for gaming?


Intel Core 2 Quad Q9400 LGA775 'Yorkfield' 2.66GHz 6MB-cache (1333FSB) Processor - Retail [BX80580Q9400] £159.99 inc VAT

or


Intel Core 2 Duo E8400 LGA775 'Wolfdale' 3.00GHz (1333FSB) - Retail [BX80570E8400 ] £149.99 inc VAT


Thanks for any input

Re: which chip?
 

q9400 gets a passmark score of 3,716
e8400 gets a passmark score of 2,197

So the q9400 is in theory almost twice as fast. In practice this could work out far less than or even occasionally more than twice as fast. This is because the Q9400 has 4 cores and the e8400 only has 2. So for a game to work faster on a 4 core processor it needs to be written to utilise all 4 cores (More games come out every week that do) whereas most current games already support 2 cores.

Personally I would and recently did go for a quad core over a dual core, because even if your current games/apps don't support it, odds are future ones will.

Out of interest what are you upgrading from?

Hi

CPU Intel Core 2Duo E650 (over clocked to 3.5 )

my son needs a new chip in his mainboard so i thought he could have my old one and i get a new upgrade :-)

Would i see much performance increase?

Re: which chip?
 

I'm not 100% sure as my experience with modern intels is mainly on laptops.
According to the passmark website there is about a 33% performance increase from the e6550 to the e8400 though this is at stock speeds and yours is quite heavily overclocked. I think You will notice it but Im not sure its worth the £149.99 price tag. Though if you are upgrading to a quad core at least you could call it an investment ;)

Here's the passmark link for common CPUs and their scores if you are interested. http://www.cpubenchmark.net/common_cpus.html

I do not really understand your post

You have a E6550 overclocked to 3.5 is this correct?

Your son needs a new CPU in his mobo whats wrong with the old chip? what cpu is it?

Would you see much of a difference if you upgrade to one of the cpus in post 1?

Going from a E6550 to an E8400 wouldnt be a worthwhile upgrade going from a E6 to a Q9 cpu would be if you do a lot of multitasking or use multi threaded application. You also need to bare in mind if your system was built when the E6 cpus were new then it may not be compatible with an E8 or Q9 cpu

Now if you were to have said go from an E6 to an i5/7 then that would be a different story but that would mean a whole new backbone

Re: which chip?
 

its a E6750 me bad and overclocked to 3.5


About a year ago i upgraded my system and what i have left over is

abit ip35 pro 4gb of ram a graphic card

The E6750 was put in my new mainboard Asus P5Q-E so no chip for the abit board.But now i have some money so was going to buy a new chip and put the old one in the abit board.

Re: which chip?
 

go onto the asus site then and see what cpu the board takes. I had the P5Q pro running a q9450 though so you should be sorted

Re: which chip?
 

will do thanks

The only thing is i can't find any in stock even when i google for one

Intel Core 2 Quad Q9400 LGA775 'Yorkfield' 2.66GHz 6MB-cache (1333FSB) Processor - Retail [BX80580Q9400]

Anyone one know a uk dealer that has them in stock?

Re: which chip?
 

Abit more expensive than other shops but

Aria

In stock aswell

Re: which chip?
 

why dont you chuck a Q8400 at it?

same core speed same frequency but lower cache but as well as lower cache a much lower price

Re: which chip?
 

Thanks for the link damien


If i got the Q8400 would there be much diff?apart from price which is nice :-)

Re: which chip?
 

2 meg cache is all the difference between the chips they are exactly the same otherwise
