AMD plans to launch two Phenom X4 and three X2 models within the next three quarters
AMD’s latest roadmap reveals the company’s model numbers for the performance and mainstream
Phenom X4 and X2
processors. Despite AMD issuing model numbers, the clock speeds are still ballpark figures and not yet set in stone. AMD has two Phenom X4 and three X2 models planned. Three of the models are set for a Q4’2007 launch.
-based Phenom X4 processors carry the GP-7xxx model number. There will be two Phenom X4 GP-7xxx processors at launch – the GP-7100 and the GP-7000. AMD plans to clock the Phenom X4 GP-7100 from 2.2-to-2.4 GHz. The Phenom X4 GP-7100 has a 3600 MHz HyperTransport 3.0, or HT3, bus speed. The lesser Phenom X4 GP-7000 has a targeted clock speed between 2.0-to-2.2 GHz and a lesser HT3 bus speed in excess of 3200 MHz. The two quad-core processors will have 89-watt thermal ratings.
AMD plans to launch one Phenom X2 GP-6xxx model by the end of the year. The Phenom X2 GP-6550 joins the Phenom line up next quarter clocked somewhere between 2.0-to-2.4 GHz. The first Phenom X2 to launch has a 3600 MHz HT3 bus speed. This model has a TDP of 65 watts.
Two more Phenom X2 GP-6xxx models will join the lineup in Q1’2008. The Phenom X2 GP-6650 will launch first between 2.2-to-2.6 GHz with a 3600 MHz HT3 bus speed. This model has a 65-watt TDP, similar to the GP-6550. The next Phenom X2 GP-6xxx model to launch is the GP-6800. This model has a higher 89-watt TDP, but still a dual-core processor. AMD aims for a 2.4-to-2.8 GHz clock speed with a 4000 MHz HT3 bus speed.
In Q2’2008, AMD plans to launch one more Stars processor based on the
core. This model does not carry the Phenom name because it’s a lower end mainstream processor without L3 cache. The Athlon X2 LS-2350 aims to clock in at 2.0-to-2.2 GHz with a 3200 MHz HT3 bus speed.
The 3.0 GHz Phenom processor that AMD
demonstrated last week during its Analyst Day
does not appear anywhere in the most recent desktop roadmap.
AMD's latest guidance explains that sample availability for AM2 Phenom will begin in the "September/October" window, with box stock during "November/December."

What I really don't like, is the similarity with Intel's model numbers..
I mean, the X2 6550 is begging to be compared to Intel's 6550, and if it comes up short in any way, the backlash will hurt.
No no, direct model number copying is not the way to go, different cpu cores have different strength and weaknesses, and should be judged by their own merits, not how they compare to a specific competitors model. Comparisons should be made based on prics/value.

I hear ya.
I did a double take, couldn't understand their reasons for naming models close to C2D chips... but I don't doubt that they
have valid reasons for doing this. Anybody care to suggest anything? Perhaps this is intentional and they really do plan to name their superior chips close to less capable Intel chips.

Here's an idea for a model system for desktop cpus, based on the current Phenom system interleaved with a page from what was used on the initial Opteron model system.
First we have the name indicating the core architecture, that's obvious. Phenom, Athlon, Sempron, ...
Three classes loosely indicating power~performance:
*X has always been associated with enthusiast (A64 FX-60, Core² QX6800, Core² X6800), so that's an easy one. >90w processors with extra features like unlocked multipliers.
*G can be retained for the 'normal' line, being associated with 'G'eneral, 'G'amer, whatever. These would contain the 65w and 89w processors.
*L is an obvious choice for 'L'ow voltage, 'L'ow power. 45w processors and below.
Numbers should be placed according to their significance for general computing performance; #cores > clock speed > cache. So the first number signifies the number of cores, while the next two the clock speed (omg!!1 u can actually know the clock speed from the model number? what a novel idea!). 28 => 2.8ghz. Model 423 would thus contain 4 cores running at 2.3ghz, while model 230 would have 2 cores running at 3.0ghz.
AMD has the advantage of not really needing to indicate bus speed like Intel (1066 or 1333 fsb etc.). The chipset powering a socket should be able to accept any released chip on that socket. A slightly lower HT speed (for example, 3.2ghz instead of 3.6ghz on the new chips, or 800mhz instead of 1ghz on the older chips) is no biggie for performance on desktop chips.
We still might need to indicate cache. This is the hardest part of this system, but since this has less impact on performance, it's not that imperative for the general populace, so we can afford making it a bit more complicated. Cache can be indicated by a letter (another number is number overload in my opinion), having a different meaning according to the power class it is in. 2 classes and thus 2 letters should suffice for this. I've chosen P and T for this, because they 'fit' neatly with the existing power classes. P could indicate 'performance', mainstream; T 'top', high end; For example:
*XT an enthusiast processor with 4mb L3 cache, XP has 2mb L3 cache
*GT a mainstream processor with 2mb L3 cache, GP has 1mb L3 cache
*LT a low power processor with 1mb L3 cache, LP has 512k L3 cache
Of course, they don't *have* to indicate different cache configurations between power classes, so if there are less cache configurations as outlined here, both XT and GT could indicate 4mb L3 cache. The same letter can also be used to indicate the exact TDP instead, or both the cache and TDP, but I don't think it's necessary a model number conveys exact TDP information.
It might sound less flashy than the "geeeepeee seven thousand", but is imo more useful.
