Piledriver - Page 30

post #291 of 627
Man I didnt know that was around. Thanks for pointing that out to me. Now Im even more confident in Piledriver. If its already benching some things 17% better than Bulldozer in a trimmed down, energy efficient Trinity, then it should have little problem hitting the 20% improvement over Bulldozer AMD had claimed. That would be outstanding! Now just please oh please dear God dont let them do something stupid and bring it out at $300. They get a 20% bump in performance and price the top dog Black Edition at $200 and its on! Itll be a very competitive alternative to an i5 Ivy Bridge sitting at $250.

Finally, a thread not overly consumed by trolls. thumb.gif Lot of useful discussion and information here. biggrin.gif

Trinity on both laptop and desktop will use one module (two cores) for the low-end and two modules (four cores) for the higher end. Or at least that's what we can expect: a dual-core and a quad-core for different price points.

Trinity on the desktop, on the other hand, has been compared to desktop Bulldozer here, but keep in mind that Trinity has no L3 cache and will certainly be slower to some extent than the Piledriver-only, L3 cached CPU Vishera scheduled for Q3.

The reason I think Trinity on the desktop and Piledriver will be comparable is that the L3 cache is the only thing that seems to be different. The problem is AMD has said in the past that the L3 cache is mostly useful in server workloads.

Now it may be lots more power efficient and I hope it is, but I really can't see how anyone can claim anymore than 10% at best extra performance based on the evidence we have, ie 2 Piledriver modules missing their L3 cache (which supposedly doesn't matter much). I hope I'm wrong but I don't see the point in being delusional about this.

Sticking with AM3+ socket


If all goes well and AMD doesn’t hit any delays, the Bulldozer successor codenamed Vishera could launch in Q3 2012. This is the timeframe that AMD is disclosing to its partners and let’s hopes that it can stick with this schedule.

One of the possible issues is that engineering samples are planned only for Q2 2012 and usually AMD provides them to platform manufactures at least two quarters before the planned launch. This can mean that AMD is launching Piledriver cores and Vishera in very late Q3 2012 which kind of makes sense.

Despite the fact that AMD already told its partners that Vishera powered Volan platform is coming in 2012, many are preparing to launch of Bulldozer desktop successors in early 2013. They learned the lesson with Bulldozer that was delayed for many quarters; let’s not say years. It is better be skeptical than sorry.

Volan uses the same AM3+ socket and will use well know AMD 990FX northbridge and SB950 southbridge, the same chipset that you see today with Bulldozer FX processors.

Of course Vishera CPU is competing against Ivy Bridge CPUs and alternatively Ivy Bridge E high end parts, both 22nm. Ivy Bridge quad and dual parts will launch in early Q2 2012, most likely April / May while Ivy Bridge E, 22nm quad and hexa-cores should launch in late Q3 or early Q4 2012 and put a lot of pressure on Volan platform.

Still AMD will have the price advantage and will in any case end up significantly cheaper compared to Intel’s solution in the same high end – enthusiast desktop market segment. It always had the advantage and it always will.
 
AMD’s current plans call for the replacement of Zambezi cores and the Scorpius platform by the new Volan plaform and new Vishera cores in Q3 2012. It looks like AMD can meet this schedule but at this point we could not find out the exact clock speeds.

We did find out that there are three CPU versions coming in mid Q3 2012, the eight core AMD FX 8350, the six core Amd FX 6300 and a quad core AMD FX 4320. The eight-core version is expected to get to engineering sample in early Q2, so any day now, it should move to production candidate sample stage in early Q3 2012 and get to production ready and production status in Q3 2012. The launch date is yet to be decided, but this all depends on the product readiness in Q3 2012. If all goes well earliest you see Volan platform AM3+ and Vishera processors is Q3 with a possibly unlikely scenario to launch them in Q4 2012.

Eight, six and quad-core Vishera come with enhanced AMD turbo core, DDR 3 1866 support and AM3+ socket. They are naturally a 32nm SOI based porocessors manufactured in Globalfoundries Dresden Fab 1, the fab that now has plenty of experience with 32nm processors. The bad part is that Vishera has to fight with 22nm Ivy Bridge and at some point server version of Ivy Bridge E, meant for enthusiast market. But don’t worry about AMD too much, the Texas-based company will definitely have a price advantage.

Anyone see this yet? Some new roadmaps and looks like AMD will be bringing out the big guns with Steamroller.

AMD Phenom II X8 2420 Seems to have PileDriver’s Specs

 

phenomii2420-cover

We have already published that AMD is preparing Phenom II X8 processors based on Bulldozer architecture, which was revealed from the BIOS of ECS, but now Vr-Zone has brought us the working prototype of these upcoming processors.

Phenom II X8 without Unlocked Multiplier

Besides the fact that the entire AMD FX series have an unlocked multiplier, which are targeted at overclockers, upcoming Phenom II based on Bulldozer architecture won’t come with an unlocked multiplier. So it means that you may not have a plenty of overclocking headroom, but still you may overclock it by increasing the bus frequency.

AMD Bulldozer based Phenom II X8 2420 Engineering Sample from Vr-Zone

Vr-Zone shows us an engineering sample of Phenom II X8 2420 which has PN / Number ZD242046H8K, has 4 Bulldozer modules i.e. 8 processing cores (each module has 2 cores) operating at a frequency of 2.4GHz, and installed on an Asus Crosshair Formula V motherboard on socket AM3/AM3 +.

What’s New in this Engineering Sample

The main difference between our earlier post of Phenom II X8 processors and the currently revealed specifications of Vr-Zone is the increase in the amount L1 and L2 Cache memories. This is purely contradictory with what we have said earlier. The leaked BIOS image from Vr-Zone shows that the upcoming Phenom II X8 will have double the L1 and L2 Cache of Bulldozer, which is almost comparable with the leaked specs of PileDriver. Pile Driver is the successor of Bulldozer, from AMD, which will be incorporated in AMD Trinity APUs and AMD Vishera Processor. PileDrive modules will get released in Q3 2012.

Reason for Superior Specs

But the reason said for this increase in L1 and L2 cache memories is that it may be due to the premature release of the motherboard’s BIOS, which is not yet ready for the upcoming processors. This may not be true too. So we will have Phenom II X8 before PileDrivers are out.

IIRC AMD Phenom II X8 are simply stockpiled ES of BD.

So the trinity chip tested had:
-2 modules (as opposed to 4)
-lower clockspeed
-no L3 cache
and showed 10%ish perf gain over bulldozer?
Explain to me how that is bad?
