Why is my AMD 8350 rendering faster than my mates 3770K

abit off topic but Martini do you know how to fix multiplier lock with an ROG board? My board won't let me downclock or raise the multiplier and it's stuck on the last setting i saved it at. It will let me adjust everything else like voltages, pll voltage, memory voltage and timings etc but the turbo core multiplier won't change! I read that a bios update might fix it since it could be a bios corruption.. but would like to hear any other options before i do that.

Ok, we did the test again. This time we turned on Hyper-Threading. Results were better for the 3770K. It managed to render the scene way faster than 8350. It only took 5min and 20 seconds.

Very good, but it's not exactly worth £200 extra just to render the scene 40sec quicker.

Funniest thing i have read on this Forum for a long time.

I'd assume your board has two BIOS's? Just switch the active one round and use the other.

But I've never encountered an issue like that though, so I wouldn't know how to fix it sorry.

It doesn't, i have the Mv5 gene board with only 1 bios since its a matx board.

Ah nvm, i guess i'll try a bios update and see if that fixes it.

Thanks anyway mate.

simple the 8350 is a true 8core cpu softimage can take advatage of that, whats actually really good is a 4 core was only 50 sec slower than an 8 core

It's not though, a 'true' 8 core CPU would have 8 identical & independent cores like Intel Xeon's do, AMD BD/PD are just 4 very unconventional cores (AKA modules).

A true 8 core CPU wouldn't lose performance when you run 8 threads like BD/PD do due to the resource sharing, or only match rival quad cores for that matter (unless IPC was really terrible).

But the IPC is really terrible though, at least it certainly was on Bulldozer.

It's hard to word it to be honest, the issue is the scaling on the module when both cores as used.
 
OP, are you aware that when you turn off hyperthreading on an i7 3770k, you're effectively turning it into an i5 3750k?

Thread is full of fail
