Intel Core 2 Extreme X6800 vs Intel Xeon E5520 .. HELP! :( Tags: CPUs Core Xeon Intel Last response: February 7, 2010 12:54 PM in CPUs Share mojodk February 7, 2010 12:03:30 PM Old PC = Intel Core 2 Extreme X6800 @ 2.93 GHz, Win7x86RC New PC = Intel Xeon E5520 @ 2.27 GHz, Win7x64RTM Hi all, I'm a DotNet (software) developer and I'm confused. I just got a super-duper-high-speed-PC, but it's slower than my old-old-PC. For example I made a simple program that counts from 0 to 5,000,000,000 ... it takes my old computer 19 secs and my new 24 secs I'm a CPU noob, so my question is ... can it really be true that my new CPU is that more slow than my old CPU? Thanks guys, MojoDK aka sad-man More about : intel core extreme x6800 intel xeon e5520 GhislainG a c 117 à CPUs a b å Intel February 7, 2010 12:54:09 PM They basically have the same architecture and you wrote a single-threaded program. The results are to be expected. On the other hand, the new system will run 4 threads a lot faster than your old one. m 0 l Can't find your answer ? Ask !
