OCUK may already have these but can't say due to NDA.

They've had them since last week.

Super PI is a well known Intel-slanted and inefficient benchmark, it's a stupid thing to use as a comparison when AMD CPUs are involved.

This.
I said AMD could release a superior CPU and superpi would still have Intel ahead.

A competitor does too.
I'm surprised by the none

thread like.

5Ghz on water will be pretty good. However, a 2600K, can also get close to 5Ghz on water. What comes into play at these speeds will be the IPC value. P4 got around the low IPC, by clocking really high. Will the BD have to do 6Ghz+ to beat the 2600K outright?

I expect the current Intel chips will out perform the AMD's in single core tests.

To me that's not so important, as when does anything single threaded today slow you down anyway. I talking about the times you sit there actually waiting.

The 'bottlenecks' in a modern applications are file compression, video editing, photoshop etc, all these are written multi-threaded apps, so an AMD 8 core should be great.

I wish people would stop saying single core tests.
As most programs aren't single threaded, they're multi-threaded, how many threads they can use however is dependant on the program, and if a 2500k bests an FX in single core, it's going to best it in until a program uses more threads then a 2500k has (And even then it's still not clear cut)

I'm more curious to see if Emulator developers will implement BD's new instruction sets or if they'll get used.

Martini1991 · 9 Oct 2011 at 12:53

Also, what's with the "THEY'RE BRINGING OUT LAUNCH DAY UPDATES"
Wouldn't they give these updates etc for the reviews?

Depends how useful they are.
I know PCSX2 team are interested in AVX. But that's SB and BD isn't it?

Maybe AMD are doing the only thing they can do to compete with Intel.

They cant go toe to toe with intel on IPC (why I dont know, just reverse engineer) so they are saying ok, the vast majority of pc buyers dont know anything about ipc but when they see '8 cores' they will be wow'ed so thats the avenue we will chase.

*
I hope im wrong. Becuase if I was to upgrade from my current quad, I would like to go next gen and that is 8 cores.

But im also now thinking, my current pc, is sufficient for the games coming out in the near future, and I should really wait for a pcix3 mobo, so at least Im set up for next gen gpu's when they are out.

In other words I may skip BD, and see what happens after.

No idea if SB has it too.

That would be awesome, I love playing my PS2 games.

Knowing both have them is a bonus if SB does have AVX.

SB has AVX. Just checked my CPUZ.

Nice, thanks for that.

But with such a low IPC, Bulldozers will only be a slight, if at all, improvement over current Phenom II's...

Which is why if official reviews confirm what we all fear about Bulldozer, i'll be going for a 2500k as i need the highest performing IPC over 2 cores i can get.

No emulator out there makes very effective use of more than 2 cores..

Quicken · 9 Oct 2011 at 13:27

Will be nice not to view this mostly negative thread again after wednesday, and goto the overclocking thread!

:-)

Hmm hopefully every benchmark is fake.

AMD don't seem to be too talkative on the subject.

opethdisciple · 9 Oct 2011 at 13:33

BD will be epic fail, if after all this time, its just a phenom2 with extra cores...

Martini1991 · 9 Oct 2011 at 13:41

There's still hope, every benchmark could be fake

CAT-THE-FIFTH · 9 Oct 2011 at 13:52

At least we know that Piledriver has higher IPC than Llano....under Linux!!

Tibbz2 · 9 Oct 2011 at 13:54

I hope these turn out decent.

If not i hope the phenoms prices drop a tonne

RizlaKing · 9 Oct 2011 at 13:56

Whatever happens my view is that BD is\was a delayed cpu it was meant to go head to head with the first gen i7's and it's biggest problem now is that the 2500 and 2600k are out. It was never designed to go up against those and as a result is not going to look overly favourable where it would have done against the older i7's. AMD is a step behind right now and BD isn't going to get them back instep with intel we can only hope that BD as an architecture is flexible enough to allow it to compete at some point in the future which i think it is time will tell.

But BD's IPC is looking well slower than even first gen i7's and at that time, there would be literally no programs to make use of 8 cores.
And they brought Phenom II out after the first gen i7's, so BD obviously was no where near ready, as we're years on from then.

opethdisciple · 9 Oct 2011 at 14:01

Well the low IPC thing does sound beleivable unfourtunalty.

The fact it was delayed, so they could up the clock speeds, is an indicator, that they needed to up the clock speeds to compensate for low IPC.

Sounds like a massive flop if it turns out true.

It changes nothing. Just refreshes the current Phenom 2 line up. A rebranding more than anything and 2 extra cores...

Is there anything about the Phenom 2's that it does well or better in comparison to Intel chip?

Or is it just about price/performance again?
