AMD has something for everyone with its new tri-core processors, but quite a lot is still marked "tentative"

AMD picked up big headlines the day before Intel's Fall Developer Forum with the announcement of its upcoming tri-core processors. 

AMD's original release did not specify if this tri-core processor, code named Toliman, would be a totally new processor or merely a stripped-down version of the existing Agena core. The answer, it appears, is both.

In an embargoed corporate roadmap forwarded to DailyTech, details of these new triple-core oddities came to light.

The first triple-core processor, Toliman, is essentially a core-disabled version of the Agena quad-core processor. It includes a full Agena package, including the 2MB of shared L3 cache, with one core disabled.

Toliman, which will eventually herald the AMD Phenom 8000-product name, is scheduled to launch in February 2008 with mass availability in March.  AMD representatives, speaking on conditions of anonymity, confirmed the initial  2.4 GHz Phenom 8700 and 2.3 GHz Phenom 8600 tri-core processors will launch with a 95W thermal envelope.

In late 2008, AMD will shift almost all of its 65nm quad-core offerings to 45nm.  AMD will then follow up these initial quad-core offerings with 45nm dual-core and triple-core processors in 2009. 

The first of these 45nm tri-core processors, codenamed Heka, will launch with DDR2 and DDR3 support.  However, AMD guidance also details that Heka will ship with two different varieties: one with a shared L3 cache, another without.  All 45nm quad-core AMD processors incorporate shared L3 cache, with the exception of the Propus family processor.

AMD guidance goes on to state that all mainstream Phenom quad-core processors, both with shared L3 cache (Deneb) and without (Propus), shipped in 2009 will feature DDR3 exclusively.  Heka, on the other hand, will feature a mix of DDR2 and DDR3 support.

Unfortunately the answers for tri-core only raise further questions.  While Heka has a unique codename, it seems to be a combination of cut-down Deneb and Propus quad-core processors. The logical conclusion would be that Heka is merely excess or defective Deneb and Propus processors from the 2008 launch. 

Yet AMD's roadmap goes on to detail one more chip: RegorRegor, which has always been described by AMD as a dual-core version of Deneb, will make its debut with variable shared L3 cache and a mix of DDR2 and DDR3 support. Could it be that Regor is a core-disabled version of Heka, which is already likely a core-disabled version of Deneb/Propus?

One AMD representative declined to comment on these 45nm processors, stating that 2009 processor launches and specifications are still "tentitive."

So, apparently, you would be a "sucker" for buying better performance at the same price? Great logic!!

And are the people buying Core 2 Solo U2200s using just 5.5W in tiny devices with great battery life suckers too, just because one core that won't be used failed validation?

Seems to me you're the one calling every one interesting in buying 3 perfectly working cores for a good price , "Suckers". What you fail to understand is that these CPU's are not in any way "Broke"

That's like saying because it didn't validate as a 3.2ghz CPU and its being sold as a 2.5 GHz, its broke. And you're an idiot for buying a 2.5 GHz CPU by your logic.

This kind of thing is common place, AMD will sell more and waste less and consumers will benefit, why you cannot see this is just mind boggling.

I assume you don't buy graphics cards then? Since half of the lower models have been the high end models with parts deactivated/laser cut.

The idea is hardly new, to disable not working areas of a chip, and then sell it at a lower price. Anyone saying they won't buy one had better not buy a hell of a lot of other things too.

Yeah, and that's why almost every comment you made for this news is rated down. Complete waste of everyone's time, including yours.

The problem with what you are saying is that you don't look at things from a price/performance perspective. While those looking to buy the fastest machine out there will care, if an AMD quad-core that sells for $250 compares well to an Intel quad-core that sells for $250, then for all intents and purposes, an AMD based machine is just as good as an Intel based machine in that same price range.

I do NOT buy at the top end of the market because the performance benefits just are not worth the extra price. This is why AMD is able to survive, because you can buy a $600 HP computer with an AMD processor that has comparable performance to a $600 HP computer with an Intel processor.

In the case of tri-core processors, who cares if they are the result of one failed core as long as the working three cores perform properly and well.

I don't know about you, but I think a tri-core is a perfect middle ground for those of us that don't want to get bolted down by a dual core, but still respect future products.

I would buy a tri-core processor anyway. It only helps price even better if they use broken quads.

Not all of us can afford that top of the line stuff that survived the gauntlet.

Why would you say you would buy one when you have no idea the cost? What if the cost is the same as same speed or faster quad-core Intel part?

There are too many unknowns today to support any kind of buying decision. Unless you're a complete fanboy.

You have no logic my friend. You're comparing of the dead pixels to a broken core is seriously flawed. To make it more accurate it'd be like buying a 19" monitor that used to be a 24" monitor, but since many of the outside pixels failed they decided to just not use the outer 5" of the monitor. Sure, you're paying for a bigger monitor, that wouldn't look very stylish, but if the remaining 19" worked just like a 19" monitor was supposed to, then I don't see what's wrong with that. Of course if that really happened on a monitor then they'd have to sell it cheaper than any 19" monitor, but that's beside the point.
