AMD preps Bulldozer-based Phenoms

Written by



Quad to eight-core, 95W to 125W


AMD rolled out its first Bulldozer-based FX-series desktop processors a few months ago, but the new chips failed to impress AMD enthusiasts, who were expecting quite a bit more from the all-new architecture.

However, AMD will use the new architecture in mid-range and entry-level chips in 2012, namely in the Piledriver core of Trinity APUs. Although there has been much talk about Trinity/Piledriver, little has been said about next generation Phenoms, which will use a similar Bulldozer-derived core.

Well, according to some fresh leaks, AMD plans to introduce a wide range of Bulldozer based Phenoms, including quad-, six- and eight-core chips. All will feature unlocked multipliers and depending on the clocks and number of cores, they will be available in 95W and 125W flavours. Clocks range from 2.5GHz to 3.2GHz and like their FX siblings, flagship models will feature 8MB of cache.

Interestingly, the new AM3+ Phenoms will retain a similar branding scheme to their 45nm predecessors, for example AMD Phenom II X8. AMD won’t go for Phenom III branding and oddly, the new chips will be unlocked, just like the high-end FX series.

One thing is certain though. AMD is destined to match Intel in terms of nonsensical branding.

"AMD won’t go for Phenom III branding and oddly, the new chips will be unlocked, while the supposed high-end FX series is locked."

Hm... i didn't get the point, maybe its vice versa? :o

The point is... that it there isn't any. I'll check, something seems wrong. The branding makes no sense, or the leaked specs are way off, or the Phenom Bulldozer cores will be crippled in some other way (compared to the FX series)... We'll just have to wait and see

I think I read it was opposite, about 3 days back. Moreover those are just Engineering Samples with B0 stepping mislabled by Motherboard manufacturers as Phenom II in Bios.

I was confused about the mistake in post. FX is nothing but Black Edition CPU an that means its Unlocked, while Phenoms (rebranded FX, of course from bad yield, that's not necessary bad) will have locked multiplier.

"Clocks range from 2.5GHz to 3.2GHz"

Thats a lot lower than the current Bulldozer. Because of the poor IPC, Bulldozer won't perform well with such low clock speed

I wouldn't be surprised if quad core Athlons beat these.

I'll shall call them Sempron FX!

Hm, I guess it was a mistake, both should be unlocked... (but I doubt all Phenoms will be)

I hope AMD is not stupid enough to do such a thing. It's a bad idea to mix the naming sceme with two different generations.

Bulldozer is obvviously superioor to the age old Phenom II, but still requires tweaking and a new B3/B4 stepping (Piledriver).

Anyways dislikeing AMD be cause off lower IPC makes no sence. Piledriver is going to be good, module aproach is better than Hyper Trading, and to me it is looking like AMD made another innowation in CPU world wich intel did not.

Precisely. The deep pipeline of Bulldozer is very much like a Pentium 4, it requires high clock rates. The mobile versions of these chips are either going to absolutely murder laptop battery life or they are going to be very slow performing. Hopefully for AMD's sake they are silly cheap to manufacture.
