Locate turbo specs for i5 7400

Where would I look to find out what an i5 7400 would turbo to on all cores, not just the single core turbo of 3.5ghz? I've googled a lot and can't find it. Is it different for each chip?

Looks like a 3Ghz base, 3.5Ghz Turbo chip. Turbo used to be linear and easy to predict but in the last few generations ( Skylake, Kaby Lake ) Turbo has been updated and is more dynamic making it harder to predict. It depends on load, cooling and voltages. You are really going to only see a single core at 3.5Ghz though.

Mine seems to run at 3.3 most all of the time, with one core going up to 3.5 occasionally, and 2 or 3 cores up to 3.4 occasionally. I just wanted to see how it compared to others. I was kind of thinking it would be slower than it is so I'm pleasantly surprised.

It used to be fairly linear. I had an i7 2600K. Base 3.4Ghz to Turbo 3.8Ghz. With Turbo enabled all 4 cores ran at 3.5Ghz, 3 cores at 3.6Ghz, 2 cores at 3.7Ghz and a single core would boost to 3.8Ghz.

They updated Turbo though as I said above and things no longer scale linearly like that any more.

Am also using a i5 7400 and my processor is also not going above 3.3 ghz.. Tried using aida64 nd prime98 nothing helped.. Temps are normal max 59C!

Old thread. You won't see more than 3.3ghz except for with a single core for a short time. A lot of times you will see it if you leave your monitoring software going while it's at idle and a background process uses a single core for a second, but with a load like prime 95 or aida64 it's going to be the all core of 3.3.
