Those tuned tr you are running there is just mighty impressive. I wouldnt think binning could do so much.
You will have to wait for 7nm to get something that can just remotely compete with that efficiency. Its 14lpp at its finest imo. Well done tuning on top of it !
It depends on the chip. My sweet spot is 3.7GHz @ 1.125. 3.8 GHz Requires me to pump the voltage to 1.1875 and it results in a temp of 76.8C under Prime95 max heat settings. This is a Thermaltake Riing 240 in push/pull configuration with upgraded (Cosair SP120) fans.
I don’t think you will see all that much of a change, I haven’t really pushed my 1950x that much due to its role... but when overclocking it thermals and power behave strikingly similar to my 6900k; they even clock similarly. Under custom water I still get 70-80c on the i7 depending on workload with P95 at the high end.
That is the cost of shrinking feature sizes, regardless of chip vendor.
This threadripper chip is very efficient at stock though, I’m really looking forward to the next iteration of Zen. If AMD separates the fabric and dram clock domains I’ll be jumping on it quick.
Oh, I'll see a difference for sure. First, the Enermax has a more powerful pump. Second, I'm going from a 240mm radiator to a 360mm radiator. Third, my current cooler doesn't cover the entire die, and it has a slightly concave shape. The Enermax is flat and covers the entire die.
Before upgrading to the SP120s, I could run prime95 with 3.8 GHz at all, and 3.7GHz was rather warm. Just by using the SP120s, I am able to use 3.8GHz for day to day usage, because nothing except Prime95 and other stress tests has managed to generate that kind of heat.
EDIT #2: Remove list for now. There were a couple typos and I'm re-testing anyways.
Note that tuning the Vcore is important, since a higher vcore raises temps even if the CPU is stepping down the Vcore. For example, when I first tested 3.6GHz, I started with a VCore of 1.175 and temps were 6C higher than the eventual 1.075V result.
