How long will Quad Cpus last?

Hmm interesting insight vertica. So really depends on what type of application you want your cpu to run for. I am guessing for majority of gaming/software programs a quad has still a long time left.

Lol I remember running CFD more than 4 years ago as part of our uni final year courseworks and that's before core 2 duo E6600 came out. Just for 1000 iterations (if I remember correctly), took hours to complete the program:D and I think that was pretty much on a single core cpu (though not sure which one). My fellow classmates were complaining of the whole slow process.

I might just be spouting rubbish here, but I swear I remember reading earlier this year about some compound being developed with the electroconductive properties of silicon, but way way way less thermal resistance, and its main use would be computing components of course.

Like I said, I dont know how true it was/is, but I cant imagine silicon being used forever

recently there was an atom-thick carbon material developed?
 
I had similar discussion with a friend down the local the other night. We both came to the conclusion (this is from a gamers point of view) that there are no games for PC out at the moment (Apart from Crysis) that really need anything like an Oct Core, so many years to go before we see such things. Hardware far exceeds game Software at the moment.
 
i might sound dumb here, but if its a pain in the arse to write a multi threaded program for multi core processors (for arguements sake, let use the 4s 8core server mentioned above), then how how amd/nvida make their drivers talk to hundereds/thousands of cores with (comparatively) little ease?

the compuond is graphene and it wasdiscovered 5 years back, it counts as a zero resistance material due to its molecular structure. This means it gives off little if no heat. Mobile phones are planning to use it in their capacitors because it is also excellent at handling very high frequencies like UHF and VHF. Mobile internet will speed up as a result.

at least that is how i understiid it :)
 
Some may last 5yrs but you'll have to be totally dumb to spend all your cash on CPU just with the hope that it's going to hold that long, better buy cheaper and upgrade more frequently - it will be safer and you'll end up with more power in the end.

You never know with todays tech what will happen, maybe next year they will suddenly find a way to optimize everything for whatever amount of cores or some new stuff will come out that will be 100% faster than the current tech at same or lower price.

Yeah I agree the computer technology is moving fast rapidly. Even the dual core cpus that came a long time ago are being utilised heavily but they still perform solid even today depending on the application. While playing CS source and Just cause 2, they seem to be taking a large chunk of each of the Q6600 4 cores.

Maybe if you overclocked E6300, then probably the time may reduce to 1 hour. But still the quad does dominate a dual in multi-thread programs

Don't believe the difference is that big to be honest.

My 2.4Ghz C2D/4G MacBook Pro encoded video only 3-4 times slower than my 2.8Ghz i7/6G Mac Pro.

Either way, quads will last a long time to come.

you sure its not a case of GPU acceleration enabled software rocks? not sure on this but..... *all numbers from top of head*

same generation of tech (pretty much) therefore IPC is similar

clockspeed = 3800mhz/1860mhz (assuming a conroe 6300 like i had)
= 2.04 twice the cores so 2x2.04= 4.08

obviously over simplified, as your quad has 12mb l2 compared to the 2mb on a conroe 6300, so 3mb/core vs 1mb/core, but i wouldn't like to comment on any linear performance scaling based on cache, not saying it not there, I just dont understand it :D

so we have at a simple estimate, a 4-5 times increase in potential power at most

2hours:5 mins = 120 mins : 5 mins, so a 24x increase in measured performance

any other factors (like RAM) are an aside from the CPU being in question

not saying I have all the answers, or that I fully understand the answers I do have, but to me it looks like more of a difference than the hardware could account for. could also be that your work client is massively bogged down by system admin tools so your employer can keep you off facebook, but I'd say there is some openCL/GL component at play here </boring rant>
 
I'm just going by the numbers *shrug*

FSB is significantly higher on my home machine, and the software in question was only using 500MB RAM.

It did max out all 4 cores though.

I don't recall enabling hardware acceleration, though it would make sense if that was in the mix as well.
