AMD 3 and 4 core CPUs...

Motoman · 28th Mar 2008, 11:40 PM

Now that they're out there, I have to wonder what the applicability is to real life use.

For example, say you've got a 3Ghz dual-core Athlon like I have. I have a hard time believing that anything I do would benefit from going to a 3 or 4 core chip, granted that the available clock speeds are much lower right now.

If you've got a 3-core chip at 2.5Ghz (7.5Ghz total) or even a quad-core at that level (10Ghz total), I don't see games or other applications being able to leverage those extra cores to the point where 2 3Ghz cores (6Ghz total) isn't going to give better overall performance.

Thoughts?

Quad-core is not yet mainstream for gaming, & tri-core is redundant to me...

Other than benchmarking, my quad truly shines when it comes to video encoding..

...that's pretty specialized use. I'm thinking in terms of things that *everybody* does...games, Office applications, etc. I just don't see 3 & 4 cores helping. Certainly not now, anyway.

my guess is that RAM, hard disk etc will be the bottle neck .. LOL ..

in terms of gamin, most likely graphics card will be the bottleneck..

Unless you run any of those Distributed Computing softwares or encoding videos, quad cores are pretty much "useless".

Quad cores are pretty limited so far especially with software support as mentioned by other members. For video encoding or rendering they are powerful for sure. As for gaming not so much.

On the AMD stuff and I think you are refering to the Phenom quads coming out been watching feedback closely and L2 cache seems to be the biggest issue with them. All things get worked out with time but for real life I don't think a quad is really needed.

I am running an E6550 Duo with a 3.0G O/C and running my 9600gt with stock settings. I don't need much more especially for gaming. My Everest CPU benchmarks match Q6600 scores and on 3dmark6 with the viddy card stock settings I am getting around 11k.

Indeed, Folding@home on a quad-core is kickass

This is why I didn't bother getting a quad core. Waste of money and power.

Yeah, for now. But eventually, ray-tracing may replace rasterization for 3D graphics. When that happens, multi-core CPUs will really take off.

Right now, quad-cores are great if you do video encoding. It may not be AMD-related but you can take a look at the performance differences between quad-core and dual-core processors in this guide - Tech ARP - Intel Core 2 Processor Performance Comparison Guide Rev. 2.3

I've still a soft spot for AMD and still wondering if my next upgrade should be Intel or AMD. I still hear AMD is no more bang for the buck. I only now wonder when they'll break through again. I hope its soon.
