wow on OCN.net someone has a 4670k @ 4.2 at 0.88v

not many haswell chip users yet.
im thinking he has a golden chip and yours is probably the norm. still a very nice vcore though. i need 1.2 for 4.5 thats good by ivy standards ull likely shave 20*C with an aftermarket heatsink

About the same, I think. I didn't really have to change the voltage to get it to 4.2.
Lucario Wrote:GHz for sandy fps about equivalent to haswell: 5.3ghz vs 4.1ghz - 29% increase
Right?
(111*(5.3/4.2))/109 = 1.29
(85*(5.3/4.2))/84 = 1.28
(131*(5.3/4.2))/129 = 1.28
So yeah around a 28-29% increase in IPC. Amazing if true.

Depends on the scenario. In your case no.
Lucario Wrote:And I heard it can do perfect 23.976 playback. Maybe not important to you but that's really good news for videophiles like me.
Not perfect. Nothing can do it perfectly. But it's within such an extremely small margin of error that it doesn't really matter. They now have the best 24p playback out of the three companies (Intel, Nvidia, AMD). And they're working hard on improving the drivers for haswell even more. They've more than doubled the number of software engineers on their driver team, which is a good sign that they're finally taking GPU drivers seriously. Something that they've horribly neglected in the past and they must change if they want to compete with AMD/Nvidia in the future.

If that 50% increase rule applies to lightly threaded applications like dolphin then you're going to be waiting for a long time.
Venomx1 Wrote:im thinkin probably skylake.
I doubt it. That would have to be one hell of a leap from broadwell.
Yes, I must have used the word "perfect" wrong. I consider it a "perfect" because it's very likely that you will not see any errors coming in real life. It has gotten SO close to 23.976 than AMD, Nvidia, pre-Haswell, and maybe everything else.
i meant if we saw same gains from ivy to haswell (19% from mine) steadly for broadwell as well i would think skylake would be 50%+ than mine in dolphin than my processer (while real world improvements would be alot less maybe 20-30% IPC wise)
moosehunter:
Could you please test also PCSX2 performance increase with Haswell? I'm trying to find owner of such cpu, but no luck. Waited of Haswell only because of Wii and PS2 emulation, but it's too hot, so if it's so fast even in pcsx2, this is great (otherwise i'll better buy ivy or sandy for safer overclocking). The benchmark is here:

Thanks!
If you're willing to post a copy of that game to the UK, I'll be able to do that benchmark in about a week.
I would love to see this done at each IR with haswell integrated graphics (HD 4600) when you get your rig AON3. And of course with discrete graphics also for comparison.
20% increase over sandy bridge. Nice. Not quite as good as dolphin but still above the average gain. Since dolphin and pcsx2 have similar workloads it doesn't surprise me too much.
