limits of the quad core?

post #1 of 10
Thread Starter 
looking at the whole multi core thing makes me wonder. what are the limits? I understand that smaller core technology (nm) will yield a lower output of heat. as things are now with my 3600+ bris i dont understand how they can really have a 4 core chip able to disburse that kind of heat on the available surface area of the processor. now given, i have my bris up to 3Ghz but i also have a big typhoon and the processor that were both polished. how are they going to keep these things cool with the stock head sink? what kind of overclockability with they have?

Dont use a quad with stock heatsink, its a bad idea.

The QX6700 is 72C on load with stock heatsink.

The stock heatsink on these processors are used for desktop computers, buy a aftermarket cooler if you plan on buying a quad even you are running it at stock.

P.S. Why are you speaking like the processors havn't came out yet?

About the overclocking, they don't overclock as much as the conroes because of heat. Top end air cooling can get them to around 3-3.2Ghz.

Also, Quad core is just a phase Octo-cores (8) will be coming out in late 08. By 2010 we will probably see around 16 core processors according to intel.

Damn, 16 cores seems so.. pointless. It's hard to max out four or even two cores, I hope adding cores to CPU's doesn't turn out to be like the MHz race of Netburst. IMO concentrating on even more efficiency (like what AMD did with A64 and Intel furthered with C2D) is the way to go..

Two or four cores seems like a perfect place to stop for the sake of efficiency for a while. I'm counting on my 170 to last me for a long time, when multicore processing takes off the 170 will get even better. Sure there will be better out, but will it be needed for the average user? What do you guys think?

I agree but that would depend on your definition of "average user". Most folks would be fine with a Sempron.

Hahahaha...yea, all my friends have Celerons and Semprons with 512/256MB, and they are all totally OK with it because all they do is surf net, email, type, all that.

Tank Guys is taking pre-orders for the Intel Q6600. They promise stepping and all, and they expect the price to be between 275-290 I just may get one around winter time, as the 45nm will be expensive at first....

Also Crysis will supposedly be quad core optimized.

When an app goes multi-threaded it uses EVERY core it has - this means that in "saved time" a Quad pays for itself in rendering etc pretty quick

yes that will be nice when multi thread is the standard along with 64bit

No, not true at all. It depends on the implementation of the multi-thread. For example, Oblivion is multi-threaded but it is only optimized for two cores. The majority of code runs on one core. The lesser and non-dependent (sound and stuff) threads run on the second core. The lesser threads account for around 20% of the total threads.

The easiest way of multi-threading is dividing up jobs which have their own threads... like physics, AI, sound, graphics, etc. In theory, you can further divide them like physics itself would be multi-threaded. However, this is much harder.

Multi-thread programming is nothing like 64-bit. It is relatively easy to make something run in 64-bit. It is just a memory allocation and sizing change. Multi-threading introduces a whole lot of issues with dead-locking and dependencies. Generally, the more multi-threading... the harder it is to test and implement.
