	An AMD E350 is a silly processor to use on Boinc Seems like my 10 years old AthlonXP 2000+ with the optimized app is about 1.5x faster. OK, that's per core, but anyway... But the E350 includes an OpenCL capable GPU which could change that picture. Sure, but I was just thinking about the pure CPU power and was surprised, that they would still build such slow CPUs. ____________ .

You would be suprised, its not that long ago that they stopped producing the 8080 and the 8088, the 80180 is still being produced and that is an 8 bit 10MHz processor, not everything needs the power or processing speed of the latest chips. ____________ Kevin

	^ It's true. Friend of mine was telling me about some 8 or 10MHz processor that he uses in his field and that it is only used for reporting readings from various sensors, and since they don't need 10 million reports/sec, it gets underclocked and undervolted by something like 75%, which makes the chip run about 2C above ambient, so it doesn't need a heatsink and will basically last forever since it doesn't get anywhere close to hot. TI-83 graphing calculators use a 9MHz processor. If you get the Silver Edition (like I have), it got upgraded to 25MHz. Lots of uses for tiny, low powered, slow processors. ____________ Linux laptop uptime: 1484d 22h 42m Ended due to UPS failure, found 14 hours after the fact

OK, I should have write "for PCs" at the end. ____________ .

OK, I should have write "for PCs" at the end. The 8080 was one of the original PC chips running at 2MHz and able to address 64 kilobytes of memory, it was followed by the 8086, 80186, 80286, 80386, and the 80486 before the Pentium. edit http://en.wikipedia.org/wiki/List_of_Intel_microprocessors ____________ Kevin

I have been out of the USAF since 82. The USAF would put a missile on an F-16 and it would fly as high as it could and then the pilot would fire the missile at the satellite and take it out with the missile. ____________

	I was talking about the speed of CPUs for PCs (desktop/laptop) which are build today (or in the past 1-2 years), just like this AMD E350 (it was released 2011). I was not talking about what CPUs we had 20 or 30 years ago and for sure not about some measurement equipment or pocket calculators. ____________ .
