OC 3930K to be core2core equal with STOCK 4770K?

post #1 of 5
Thread Starter 
Hi, I was wondering is it possible to OC 3930K that far to be core2core equal(single core - in terms of speed of course) with STOCK 4770K?

and what do you think about up-coming 4930K? is this CPU going to be core2core(STOCK) close to 4770K(STOCK) speed?

Thanks thumb.gif

fairly confused what your getting at? I'm sure there is someone who may know better what you mean.....

I take your question to mean "is it possible to get 3930k OC up to where its instructions per clock is equal to the 4770k cores instruction per clock?"

I would say the answer is YES. Haswell is 10% faster ipc, but aparently runs hotter somehow than ivybridge. so 4.6 might be a moderate OC on haswell where 4.8 could possibly match it on ivy.

3930k vs. 4770k is a no contest though id say bc its 6 vs. 4 cores.......so it should outperform it hands down even if clocked the same and probably even if the 3930k was at a slightly lesser clock

You are looking at a 20% IPC increase (ballpark), so a 4.5~4.6GHz OCed SB-E should be a close match to a 3.8GHz boosting 4770K core.

An average 4.3GHz OC on haswell is already "uncatchable" by a SB-E chip unless you win the silicon lottery and get a chip that can do more than 5.1GHz under down-to-earth cooling and vCore.

The average IPC increase on the Haswell series versus the Sandy bridge, Sandy Bridge E series is 15.9%.

This would have a 3.8Ghz Haswell chip equaling a 4.4Ghz Sandy Bridge Chip. Non Delidded Haswells (they still have their warranty) will have problems above 4.5Ghz with any cooling other then Subzero. I have tested 9 Chips and this is my determination. High end air and Water cooled Sandy chips can easily reach this thresh hold. Add in the extra cores and this is no comparison. Intel chose to go the non-soldered route on the mainstream series and it will push sales to the X79 platform for us high end users.

nice accurate answer mate! really appreciate it smile.gif

I've two more questions please, how do you calculate an average IPC increase over another chip? what's the mathematical theory to calculate it? so now to this matter I'm wondering what would be the average IPC difference between 4770K and up-coming 4930K?, I'd love if you explained by the same theory just like you did in this case "This would have a 3.8Ghz Haswell chip equaling a 4.4Ghz Sandy Bridge Chip" I need an example like this comparing 4930K and 4770K if possible, thanks smile.gif
