So I got myself a 3770K, upgrading a 2700K, and would like to see how my overclocking experience rates.
Yes, I know from a performance perspective, there was absolutely no point in upgrading a 2700K. I have advised others of such on this forum. I just get this itch every few months and want to play with something new. I guess it's what having a hobby is all about.
After a couple of hours experimenting, I've kinda settled on an all-4-core overclock of 4.74 GHz. A higher overclock either blue-screens when I fully load the CPU or, with a higher voltage it runs stable, but not at temps I'm comfortable with.
How does that rank - good/bad/average? From my basic research it seems about average - noting that all 4 cores are running at this speed.
This compares with 4.84 GHz (again, all 4 cores) that I settled on with my 2700K.
Running Cinebench and Core Temp simultaneously I get the following results:
- Ivy Bridge at 4.74 GHz: During the test - VCore 1.328, temps hover around in the low 70s, score: 9.47
- Ivy Bridge at 4.84 GHz: During the test - VCore 1.4 (or thereabouts, didn't take a note), temps mid 80s, score: 9.65. NB this was experimental and once only. I'm not really comfortable with VCore of above 1.4 for Ivy Bridge or temps in their 80s. Nevertheless, it is interesting to compare with Sandybridge at the same clockspeed.
- Sandy Bridge at 4.84 GHz: During the test - VCore 1.46 (or thereabouts), temps mid 70s, score: 9.37.
Interesting that my clock-for-clock comparison yields a 3% performance advantage for Ivy Bridge.
This validates what most people are saying about IB vs SB. No point upgrading from a performance perspective. Achievable overclocks are higher with SB than IB, wiping out most of the already very small performance advantage.
My cooler is a Noctua N-DH 14
