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."

RE: OK, say the thing tops out at 2.4 GHz

Why's that? Theoretical FPU power, core has a definite advantage over Phenom.
"Another impressive area is Core's SSE multimedia power. Three very powerful 128-bit SSE/SSE2/SSE3 units are available, and two of them are symmetric. Core will outperform the Athlon 64 vastly when it comes to 128-bit SSE2/3 processing.
On K8, 128-bit SSE instructions are decoded into two separate 64-bit instructions. Each Athlon 64 SSE unit can only do one 64-bit instruction at a time, so the Core architecture has essentially at least 2 times the processing power here."
This was comparing K8 to core, while Phenom doubles K8 capabilities (so 2 128bit units instead of 2 64bit units), Core still has an extra FPU unit (3 128bit units, of which 2 are symmetrical) and higher clock speeds.
The only thing that keeps Core's advantage in check is less memory bandwidth, but that's why it has huge caches.
Based on all the information we received, my original assessment is more likely. INT was already pretty strong in K8, and with all the core improvements, should be topping core's. SPEC benchmarks rarely pan out for the consumer/desktop market.
