Is AMD 960K Athlon Excavator likely to beat intel 2500K sandy bridge?

[Arachnotronic]

Looks at 860K....Looks at Cache....looks back at you....what?



Also...why do people right now assume that 960K is even going to be a thing. It's looking more and more like AMD showing every FM2+ owner the middlefinger and not even bothering to put Carrizo on there.

AM3+ and FM2 might have both received multiple generations of hardware...but it doesn't (unfortunately) look too good for FM2+.

Either AMD is really just keeping silent about it (not so likely) or they decided to drop FM2+ Carrizo (likely).

And even IF there was going to be a 960K...it might just be another Kaveri based chip....which could mean that there is no real performance gain to be made other than clock.

Carrizo probably sees a significant lopping off of top frequency to improve efficiency at more mobile-focused power levels, which would make a desktop Carrizo pointless.

It would only make an Athlon somewhat pointless. (Unless the price was super low.)

The GPU in Kaveri is still a huuuuuuuuge bottleneck(thanks to crappy DDR3 limitations...that Carrizo ought to fix at least a little bit)...so their product isn't exactly well rounded.

If Carrizos' IPC makes up for the frequency loss and the GPU improves lots....then there would be a big point to it.


But as it stands now....of any of the unlikely things to happen...the most likely would be a Kaveri Rev B or something like that. (Or even a cranked up Athlon).

But even that is a rather vague hope.

It's really just a matter of AMD giving up on FM2+ after a single generation of chips and abandoning those few people that trusted AMDs words once again...fool me once shame on you...fool me twice...

With AMD on the same 28nm process, is Carrizo still going to be a full Excav core as they originally intended? Really a shame they are still on 28nm.

Kaveri was a very nice upgrade from previous.

How so? CPU performance was improved only a few percent at most because the higher IPC was nearly cancelled out by the lower frequency. IGP may have improved more, but it still is heavily bandwidth limited, so still is in the niche area of more than the average user needs, but easily beaten by a discrete card if one needs gpu power.

If they bring 40% improved bandwidth utilization to carrizo, you can see a noticable increase in "heavily bandwidth limited" apu.

We don't know the clocks yet, so I don't know how you made to that conclusion about CPU perf.

He was talking about Kaveri.

I was referring to the difference between Richland and Kaveri, in response to the poster who said Kaveri was a "nice upgrade".

I make no prediction on Carrizo, although I would be surprised at a 40% increased effective bandwidth.

Excavator/Puma+ on 28A will have the same performance and power as if they were on 20LPM.

This is where the 40% claim comes from.

3dmark isn't BW heavy generally speaking. And this is a fairly nonsensical claim as the 280 has more than sufficient bandwidth.

Ohh.. sorry. I missed that part.

MT went up well. IGP was even better. I see it as nice. May actually replace my current Core2 setup with it in the future. Edit: Also I was talking about core improvements compared to previous not clockspeed. Not a specific chip model. Kaveri as a whole.

If AMD abandons FM2+ socket and does not bring atleast excavator then I doubt AMD should even look forward to K12 in 2016

They will most likely be looking forward to bankruptcy. 2 years abandonment and no future release on any of the current socket would drive AMD into its own grave.
Could the new CEO have been a terribad replacement?

 

[burninatortech4]

If the 7850k and 860k are the end of the road for FM2+ I am extremely pissed. I know there's no concrete information either. AMD sucks at marketing.

 

[formulav8]

Hmm, I thought Carri will be FM2+? At least my understanding on their roadmap iirc. I may not buy an FM2+ mobo if Carri isn't compatible....

My concern was not compatibility. It was the potential for AMD to only release Carrizo and Carrizo L in the laptop space and abandon a desktop performance variety. They have failed to announce Carrizo desktop variants so far if I'm not mistaken.

This.

IF we see new CPUs on FM2+...it would seem like those CPUs would only be a revision B of Kaveri chips...

Excavator might never see the light of day on Desktops. And even with all the hate that the FM2/+ socket is getting...it was a nice and cheap (fun) overclocking platform.

FM2 chips reached 5GHZ while FM2+ Chips still reached 4.5/.4.6(4.8 in rare cases) GHZ but made up for it with raised IPC.

Especially the APU versions were fun to mess with for me. Really enjoyed torturing NB, GPU and CPU to the max until the VRMs start burning. (those ridic voltages <3)

I thought the man who built the athlon that kicked intel's ass was back?? And from what I have read before that they will abolish the modular design of AMD chips?

That is further down the line....that stuff is like 2016ish. You don't expect someone to be hired and a new hardware generation to be ready within a few weeks...right? ;p.

They know that the entire Bulldozer line is a failure...but they can't afford to not put ANYTHING out...so while they're working on the next (or should I say last?) architecture they're following their plan of going all the way to Excavator....just not for FX.

The man who built the Athlon (K7) was Dirk Meyer, AMD's (fired) ex-CEO.

Oh, sorry. That was not the man im referring to. This was the guy:

That was the Opteron/Athlon 64, aka K8.

I wonder what the outcome might have been for AMD if they didn't buy ATI?

Athlon X2 was such a good chip compared to Pentium D its unbelievable how AMD reached the state they are in now.

My library in school has some old PCs Dell optiplex running Pentium D and if I could only tell you the garbage they are. You would never touch it with a 10 foot pole

I had a couple of Pentium D's back in the day (805 and then the 925) and they performed well enough at the time.

They're probably garbage now because the Pentium D is ancient

My point of view, if keller fails to deliver for AMD then there's no looking back for me on AMD processors. I have been a loyal follower of AMD since the beginning of the 486, I just switched to intel thrice. First I got the Pentium 200 MMX then went to core i5 750 then this ivy bridge that I have right now, the rest of the way, I have owned AMD processors.
