From what i have read on it so far the flagship performance chip from both companies will remain the single core CPU even after the introduction of the new chips. |

Dual processor chips are obviously just possible (perhaps by reducing the clock rate). Quad or worse would probably be exponentially harder to do (or hotter). | Graham L (2) | ||
| 328000 | 2005-02-27 07:47:00 | I run a few dual-processor systems, mainly for graphic/development work and a server. All the workstations are single processors. The good thing about dual-processors is basically load balancing, it's nearly impossible to do 100% CPU usage with SMP computers, and I've tried some CPU intensive programs out. Now the speed of dual-processors, is roughly 1.5 times the speed, it's never the equivalent of adding the speeds together, although in same cases it can be, but not to give people the wrong ideas, as it's not always the case, 1.5 is good enough. The benefits really come down to how it's controlled, the OS can take care of the load balancing, or you can control it yourself. Some graphic software are SMP friendly, so you're bound to benefit in these situations, and sometimes better than single processors. Windows 2K and up and Linux is well suited to these types of machines. Only a few software for Windows support SMP, but what the OS controls makes it suitable in any case, for any software. Linux, you can find a great deal more of software written for SMP configured machines, but then again, Linux programs are usually optimised for different processor setups. Disadvantages, well, Windows was disappointing, graphic card drivers, were not developed for SMP machines, in which case a lot of unstable activity use to happen. It seems ok now though and more software supporting SMP machines are coming out, had to find a Utility to customise load balancing instead of letting Windows handle it. Shared IRQs and Virtual IRQs use to cause major crashes, and chipset drivers were also a problem at some point. Again most of these problems are not apparent right now. If you ran Linux you would be better off, otherwise single processors would be my choice for Windows, although Windows XP, from about 6 months after it's release it was stable enough. Gaming wise, again depends on how the software was created, but games never worked with me on Windows XP with dual-processors, well at the beginning, games run ok now. If you're into 3D animations, modelling, rendering, etc, then SMP machines might be the way to go. Kame. |
