Quick question?

What clockspeed does the Bulldozer need to be at inorder to match IPC of the Sandybridge. Single core IPC

I'm talking standard Sandybridge I5 2500k vs BD equivalent

PS This is not a flame thread, A friend is writing an essay for college and although I provided her with a crap load of information, I can't for the life of me remember any specifics with regards to clock speeds. I think it's something like a stock 2500k at 3.3ghz requires a BD to be at 4ghz. But like I say, I forget.

1 core vs 1 core the 2500K is approx 40-50% faster with both at stock speeds. (AMD FX-8150 - 3.6GHz)

In theory (not always possible) you have to clock the Bulldozer to 5 Ghz - 5.4 Ghz to match.

If you over clocked the 2500 to 4.5 Ghz the Bulldozer would need to be at 6.3 Ghz - 6.75 Ghz.

Note the bulldozer does have 8 core so this is only relevant to 1 core process.

Thanks for that. Yeah I'm aware more cores make a big difference, as does hyperthreading.

Her assignment is IPS and IPC based, pretty cool sounding assignment. a lot more in depth than anything I touched on when I was in college doing IT.

She's not happy though, as she's not clued up on any of it. to the point she wouldnt have a clue how to put a machine together

Ohwell, She will do soon.

I've introduced her to Machine Language, Binary, Instructions, instruction sets, Instructions per Cycle, And instructions Per second.

She's a little overwhelmed, but I think I've clued her up on the best bits to try and grab a distinction.
