AMD "Vishera" FX-Series CPU Specifications Confirmed

[Frick]

Afaik phenomII was the hand crafted one, Bulldozer used automated system but low density libraries made for cpu's, piledriver is automated design yet hand tweaked and also using High density libraries(used already on GPU's) with their autorouting software

See cadaveca's post above with their own slides saying BD was handcrafted.

See cadaveca's post above with their own slides saying BD was handcrafted.

Their own slides, shown by Mark Papermaster, when talking about STEAMROLLER.

Piledriver will NOT see the design library enhancement. Piledriver will not really offer all that much more over Bulldozer. I expect maybe 15%, and most of that due to clockspeed increases.

Oh missed that. Still, BD handmade.

 

[AvonX]

I don't think BD was hand made.
They are just saying this to have an excuse to continue using automated tools.
Personally i think its BS that BD was hand made.

Yeah well it's hard to prove anything in this matter.

Hard to prove either way, but given the process used, and the time given to use it, it's more than likely that a large part of the chip WAS hand-made, since the company producing the tools, AMD's foundry partner, would have largely been using AMD tech to build those tools.

WHatever the truth of it is, that's AMD's official stand on it, so what we think, and the truth, hardly matters. What matters is that AMD manages to capitalize on these chagnes, and turn them into either power savings, or extra perforamnce, so that they can stay relevant to the market as a whole.

I remember back then that they did not even get the correct transistor count of BD when asked.
Yeah sure it was handmade.

"They".


They fact remains, who was "they".


Liek I get that, but you know, the whoel Fermi thing, and why i brougth htat up, was that Jen-Hsun admitted that the rel problem with Fermi was a alck of proper leadership. Like, he actaully admitted he failed. HE got red in the face, but he did admit it. My respect for him increased over 9000.





So, bad figures, eh? Someone got a number wrong? COuld have been a typo, could have been on purpose, could have been subterfuge to mis-lead the competition. Could have just been stupidity. Personally, that was all before Papermaster took over, so I don't care.

Agreed Piledriver won't be physically modified but it was stated they tweaked the he'll out of it such as tightening and enhancing the L2, L3, Branch Prediction and so on, things requiring to get ironing out before they slap together Steamroller via the new 28nm process.

Personally I can see Piledriver being at least 10% faster clock for clock versus Bulldozer with another 5% faster due to higher clock speeds, hence we have our 15%.

Any official work on the Vishera to be released?

Hope they will just skip it and release SteamRoller.
A plus 35-45% would not hurt anyone.
I need to upgrade my 1090T, its been too long.

 

[Covert_Death]

honestly is SteamRoller comes out 1H 2013 and supports AM3+, ill wait for it

Forget about AM3+, go directly to AM4 with PCIE 3.0 and some DDR4 memory.
If they do that it will sell madly. First motherboard to support DDR4.
But that is just a wild dream.

Remind me please, what is the current availability for DDR4 memory modules, and what availability is expected to be at the start of 2013?

I haven't checked lately what is going on with that, but i think whoever wishes to use it, its available. I think samsung has the lead on that.
Well of course they will use it on servers first. But why not? Lets see something different for a change.

Steamroller on AM3+ would be awesome. DDR4 ain't happening until 2015, and if that. Like I said before Intel is not going DDR4, they are sticking to DDR3 for a few years more.

We don't need DDR4 for desktops right now, DDR3 does the job just fine.
Now Servers & Workstations are all different story. DDR4 will be coming out for those probably in 2014.

Benefits

Its primary benefits compared to DDR3 include a higher range of clock frequencies and data transfer rates (2133–4266 MT/s compared to DDR3's 800 and higher) and lower voltage (1.05–1.2*V for DDR4, compared to 1.2–1.5*V for DDR3) with current remaining the same. DDR4 also anticipates a change in topology. It discards the multiple DIMMs per channel approach in favor of a point-to-point topology where each channel in the memory controller is connected to a single DIMM. Switched memory banks are also an anticipated option for servers.

That is not true, DDR4 (or even 5) would be a welcome performance boost for most platforms, go read the newest Corsair 2600 review to see.

Maybe not in intel's case but AMD could benefit from the speeds of DDR4 to feed the CPU.
Something related to that is this: http://vr-zone.com/articles/how-amd-can-steamroller-the-competition-in-2013/17105.html

I think DDR4 is coming sooner than you think it will. They are pushing hard to use this technology sooner.

I fully agree, I like the DDR4 Specification. What I meant is this is going to the Server/Workstation market, them comes the desktop. I mean I can always just sell my Crosshair V (my gaming buddy ), but I will have to be convinced going DDR4 is the right move in terms of price/performance and hassle of ripping my PC apart. Which yes I would EnJoY....

Wow, great find. I am starting to get exited. Anything to breath new life in AMD and for competition...

And here is a killer Quote. It's great he works for AMD...

Yes i have read that one to.
And something else as well: http://www.jedec.org/ddr4workshop

 

[Super XP]

I am itching for a Piledriver upgrade providing it offers better gaming performance over what I have.
So reading the article, it looks like we are going to see Steamroller & Excavator sooner than we think. Piledriver may now be short lived, because all the news is about Steamroller.

Yes PileDriver may be short lived.
Here's hopping Jim Keller can fix this crap they have been doing at AMD.

I knew, and posted on here before the release, that the problem with Bulldozer was poor cache bandwidth, specifically, L2.


Why that performance is poor, I dunno, but THAT is what needs to change, and it doesn't take anyone special to be able to recognize that.

Agreed, but also having a single decoder killed BD. Steamroller seems to fix this and some. I also have to give thumbs up for AMD trying something way out of the box. Talk about having Balls of Steel.

 

[Steevo]

Calling bullshit on the core starvation, single threaded clock for clock it performs worse than the older generation. Perhaps that is caused by L2 bandwidth, but that can be checked with some math, that is unless they had to introduce artificial latency to keep the core clock up or for other reasons.
