wattage of processors - sempron/intel cel "D"

**fuctup** · 11-19-2004, 05:33 AM

i searched this, and i know of the wattage calc. on that site, but it does not have the processors im lookin at..

i am still configuring my car pc, i need help finding out the wattage of a few of the newer budget processors , the AMD semprons (2200+/2300+) and celeron "D"s (315) and the p4 based celerons.

also, does the voltage of the processor have anything to do with the wattage ? most amd's are 1.5-1.75v, but the celerons are lower, 1.25-1.4v

thanks for any help.

voltage is not the concern...
try to look for amd-m procc. I think they are 2 ghz and go as low at ~8 watts...tahts one of the proccess i am waiting to test to see if they will work for the retail packages from dice

ya the amd Mobile is about $80 though, the processors im lookin at are around $45

I am running the AMD mobile 45W, but the mobo doesn't recognize the CPU correctly. I have to do "pin mod" to have the mobo to recognize the CPU as XP2400+. The 150W AC PSU (12V@4.5A, 5V@18A, 3.3V@5A) works wonder with the combination. However I have a small problem running the Sproggy MK4.5 PSU (2x12V@5A, 5V@10A, 3.3V@10A ~200W). Playing Winamp and GPS is fine, but as soon as I enable VIS on winamp, the computer freeze. If I use the DVD drive, the computer either freeze or reboot and so does cranking.
The 2 power supplies I used are basically the same wattage output, but different from each rail and one works but the other doesn't. After googling for the solution, I found the problem I have (I think) is that the Sproggy PSU doesn't supply enought power on the 5V rail. I am in the process of redo my PSU to increase the output on the 5V rail.

So the norm here is that the same wattage output doesn't mean they are the same and will work with your combination. You have to search and figure out which rail the mobo + CPU + add on card and stuff use power from. If the combination you have use more power on the 12V rail, find one that has more output on the 12V rail.

Lots of CPU info in this Tom's Hardware Guide article. Check the Comparison Table at the end of the article.

matrixPC, i plan on using a opus, so rails and junk is not my concern, i just want a low power processor that does not suck or cost alot.

ecar- thanks for the info, but again that does not have the celeron D or sempron's.
