AMD Athlon 64 2800+ Processor Socket 754 Retail

Yeah, both are 2800+ Newcastles.

The manufacturer SKU is different, but I can't see anything other than packaging looking diff?

One has the newer AMD retail package, and the other has the older style packaging.

Same chip, ZZF probably just has some old stock.
 
512k less chache which means a lot less silicon and transistors. Also, the San Deigo ocs better ue to the increased chache i think.(The FX57 is basically a oced 3700+ San Diego)
 
The San Diego doesn't OC better than a standard Venice. If anything, you might get a worse OC with a San Diego, because of the increase of chance of failure rate with more transistors and an increased cache. I guess the San Diego core puts out slightly more heat/power... and this is like 1W more per 100W or something... very small. But I would go with the 3700+ over the 3800+ just due to the increased cache and probably equal OC ablity. But the cache increase is expensive to put on a chip and tougher to get perfect yeilds without some cache failure in manufacturing, so that would explain the cost.

sry for hijacking this thread but can anyone explain in short why the 3800+ Venice is about a 100 bucks over a 3700+ San Diego? ty.


Well, the 3800+ Venice has got a 9% increase in clock speed over the 3700+ San Diego. Thus, you get an increase in price. While the 3700+ San Diego may be a better value for an overclocker, the majority of AMD's customers will never overlock their chips.
 
9%, thats much. but i expect only 3-5% in overall performance due to the san diego`s larger cache advantage, from some reviews i just read.

2200 to 2400 is a 9% increase in clock speed. Not factoring in cache size.
