How many cores do you really need? - Page 4

post #31 of 55
Well as i do a lot of motion graphic stuff and video work i need all of my 8 cores. My previous 4 core was good but now it's just silly how quick things are ( im actually rendering a 15minute video now while i type ). But like others have said, its more than just cores its how and what they are used for. For me AMD FX does exactly what i need it to do, whether its true 8 core or not the speed of my work is more than doubled from previous quad core.

Id say...

Light PC user = 2 Core
Medium PC user/gamer /video editor = 4 Core
Heavy PC user = 6+ Cores

Well it depends. Example BF3 uses up to 6 cores/threads. An Intel 4 core can still handle Bf3 with little to no performance lose. Amd on the other handle needs that true 6 cores to play's BF3 so it doesn't have the performance lose playing the game. The Amd chip if it's a 4 core playing Bf3 will be bottlenecking and you will have some performance lose.

No at all bashing AMD here guy's just saying that it's better for you to have more cores with the AMD chip's.

You have lower standards of what constitutes usability than I do. I still use a 2 GHz Dothan-powered laptop all of the time (which I upgraded from a 1.6 Dothan), but I wouldn't want to use a 900 MHz Pentium M for anything. Intel's Core Solo was Dothan with a bigger L2 cache and a 667/800 MHz FSB, so I would say it's pretty darn close to Core.

As far as the A64 goes, I hated it anytime I tried to use my friend's A64 with the single-core 3200+ in there, but when the dual-core 4400+ went in, it was like night and day.

You can use an old single-core CPU and it might still be passable, but I wouldn't want to use it. I guess using a Thuban has spoiled me. LOL

Now my view is that when are you truly going to use more than 4 cores, so I would like some other opinions. How many cores do you truly need?

I think that you are fundamentally asking the wrong question. Cores are just a means to an end. They added more cores to the CPU because that was the best way to cram in more performance. If there is an 30 core CPU that performance better then a similarly priced 4 core then the 30 core is better and if there is a 1 core CPU that is faster then that is better.

The question is how much and what kind of performance do you need. Core count, clock speed, IPC and other features are just way of achieving that performance.

From what I can gather it's better to have more performance in less cores, but not too little amount of cores cause that's bad too. I think that Intel quad cores are the perfrect blend, especially the i7 models having hyper threading, tons of performance with up to 8 threads is awesome.

Nah, you just want high IPS on each core.

You can have as many cores as you want with no downside as long as your single threaded performance is stellar.

An 8 core Ivy would be pretty baws, but pretty expensive 'cause Intel. I don't even think they could fit 8 cores on a 2011 die at this moment.

As many as possible, where frequency of each core isn't compromised in speed.

For games and desktop use, 4 cores at 3.5 GHz are better than 8 cores running 2.4 GHz.
