Steamroller? - Page 162

There was no IPC issues with Agena, it did have a throttling issue because it was 125+ watts. Everything was fixed with the die shrink, do to the better tools.

I meant how everyone was disappointed with the performance it brought when it released. Agena itself was delayed and as such people viewed the performance it brought as disappointing compared to what Intel had at the time. Phenom II was supposed to compete with the previous Intel generation, and if it did, it would've looked a lot better than it did when it launched in late 2008.

Phenom FX was two Agena dies and Phenom II FX was two Deneb dies, while the 32nm Phenom II FX was a true-octal core.

I think I remember that now. Weren't these chips part of AMD's old QuadFX platform?

You mean the "quadfather"? These are older, athlon-era.

Kaveri sounds nice,but half of it is GPU,with only 512 stream processors,bringing it to about HD 7750 performance. Indeed,it's quite a step up from less than HD 6670 performance,but could be even better. CPU performance can't go up very much,it's said to be about 15%. Intel is releasing new CPU's in 2015,which makes me hope AMD will be have some Mantle or HSA support by then.
The ASRock Extreme6+ looks like a solid board,although some ASRock boards have weak VRM's even though it may have more of them.
An APU version of Bulldozer would have been more exciting than cramming a GPU onto a Athlon II die. A Bulldozer APU probably didn't run cool enough for mass production,Bulldozer CPU's were a blast furnace on their own.
Phenom II octa-core? AMD would have sold so many of those things,though I had heard AMD couldn't fit more than a hexa-core onto 45nm and they were having trouble with 32nm at the time.
Sorry, but Phenom II was by no means a better arch, cramming 8-cores leaves you with a glorified Athlon 64 with old features...

Kaveri in my honest opinion is going to be almost exactly like Agena. With some alterations here and there but it should be almost like Agena.

It was delayed but the clocks are way below expectations:
3.7 GHz + 0.72 GHz is far from the expected ~4.4+ GHz and 0.9+ GHz.

Also, if you guys haven't noticed GlobalFoundries updated their website.

I do think the reason why Kaveri is at TSMC not GlobalFoundries is for Gate Last, to improve scalability to 20nm and FinFETs. Which at GlobalFoundries 20nm/14nm has moved to Gate Last for the improved performance. The move has basically allowed 28nm HPP and 20nm LPM to be six months from each other.

True,Phenom II lacks some instructions,improved turbo,and better IMC that FX has,but even with all that Phenom II still has very close IPC due to FX 8xxx being a quad core.

Kaveri could be like a Deneb,without the high factory clocks. Deneb ran much cooler and got a better IMC too. Since the process isn't getting much smaller,after a 512 shader GPU gets its share,you have to keep the TDP down somehow? I really hope the Steamroller core has enough IPC improvements to make up the lack for clock speed. AMD can't really afford another Agena core since Kaveri is being hyped so much.

Its fabbed by GF in Dresden. The ES's say "diffused in Germany".

Too early to conclude that final CPU clocks are 3.7GHz. Also turbo is unknown. With a 10% increase in IPC (on average) 3.7/4 turbo gives Richland performance at lower power draw. If you want more then overclock, this isn't some locked down i3.

The FX-8xxx/9xxx series are both octal-cores.

Lower pwer draw could mean better overclocks,if not the IPC makes up for it anyways,if it's atleast a 10% improvement.

Yes,i realize they're all cores,but half of them end up sharing resources . Not trying to argue over if it's an 8 core not,AMD markets it that way,Windows sees it as 8 cores.

Actually lower power draw is just an assumption on my part since the clocks are lower and its on a 28nm process ... but you never know.
Yes I'm thinking the IPC gain will be 15-20% on average.

Actually, the resources are in the same area but are not shared.

15h 00h-2Fh core:
2 decoders -> 2 ALUs

14h/16h core:
2 decoders -> 2 ALUs

The idea of anything being shared in Bulldozer, other than die area is a marketing gimmick.
