llamafilm Posted January 27, 2014 Share Posted January 27, 2014 I just noticed that used Xeon E5620's are selling for more than used X5650's on eBay. That doesn't make any sense to me, can anyone explain? E5620 is 8 core 2.4GHz X5650 is 12 core 2.66GHz I have the dual 5620 Mac Pro. I can trade up my CPUs and actually make a profit!

vbetts Posted January 29, 2014 Share Posted January 29, 2014 The 8 core xeons have higher yields compared to 12 core yields. Supply and demand. Link to comment Share on other sites More sharing options...
llamafilm Posted January 29, 2014 Author Share Posted January 29, 2014 What do you mean by yield? Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted January 29, 2014 Share Posted January 29, 2014 Higher yield means that more of them leave the assembly line without flaws. Link to comment Share on other sites More sharing options...
llamafilm Posted January 29, 2014 Author Share Posted January 29, 2014 Ok so the 8 core has more supply... That doesn't explain why the demand is so much higher that it costs more than a 12 core Link to comment Share on other sites More sharing options...
vbetts Posted January 30, 2014 Share Posted January 30, 2014 Higher yields=higher dependability. They'll last longer under stress. There's enough supply and demand to inflate prices on the 8 core Xeon's. If there was too much demand but not enough supply, prices would probably sky rocket. If there wasn't too much demand, but a huge supply then prices would plummet A good number of times, used Xeon's go pretty cheap anyway. It's all economics and trading. =] 1 Link to comment Share on other sites More sharing options...
3.14r2 Posted January 31, 2014 Share Posted January 31, 2014 Quite similar situation is with ECC vs non ECC RAM (Desktop vs Server RAM) on eBay. Sometimes pricing on eBay is beyond my understanding. 1 Link to comment Share on other sites More sharing options...
vbetts Posted January 31, 2014 Share Posted January 31, 2014 Ram is difficult to judge, as flash and ram memory prices fluctuate constantly I've noticed. Just a few months ago, you could get a decent speed 8gb ddr3 1600 kit for $40. That price is now near $70 just starting off for 8gb 1600 kits. 1 Link to comment Share on other sites More sharing options...
