In the market, do we have motherboards that can install 2 P4 or AMD CPUs?
If the hardware is VERY good and the software (and operating system) is VERY well written you may be able to get a 90% improvement in some rare cases.Originally posted by Saint
How much it boost the performance of the PC when compared to a single processor PC ?[?]
Thats 40% WHEN MULTITASKING. For single thread applications there is zero difference in performance.Originally posted by mcleodnine
I've ben reading some good things about Intel's Hyperthreading technology. In short it can generate anywhere from ten to 40 percent increases in performance when a compatible OS is used. I believe IBM ran some benchmarks a couple of months ago comparing 'regular' and hyperthread architectures using XP Pro and Linux (not sure if it was a stock kernel or patched). Google for more answers.
As previously mentioned the performance results for dualCPU designs are highly dependant on the OS (WinXP Pro, Win2K, Linux, xBSD, SolarisX86) and the ability of the application to utilize it.
Q: Does Microsoft still require a license for each CPU in a machine?
Not sure if you're saying you don't believe me, but in any case, this sentence is key:
"multithreaded applications"The results on Linux kernel 2.4.19 show Hyper-Threading technology could improve multithreaded applications by 30%. Current work on Linux kernel 2.5.32 may provide performance speed-up as much as 51%.
