Roadmap Update: Pentium 4 6xx now with Enhanced Speed Stepby Kristopher Kubicki on September 1, 2004 9:57 PM EST

Although we are always excited to see new processor lineups from Intel, this weeks APAC roadmap showed us the most ambitious processor rollout since Prescott.
For starters, Intel will release 4 new SKUs of Socket 775 processors based on 2MB L2 cache revisions of the Prescott core. However, the new 6xx processors are not just Prescotts with extra L2 cache slapped on them. In fact, the most interesting addition we noted with these new processors is the addition of Enhanced Speed Step Technology (EIST, also known as ESS depending on your circles). Up until now, EIST has been limited only to Pentium M processors. For those not familiar with EIST, it is simply a feature which allows a user to dynamically clock the processor during operation; very much like AMD's Cool 'n Quiet. This would certainly be a welcomed addition to the NetBurst architecture as cooling issues are more and more prevalent as Prescott ramps up.
|Intel Desktop Lineup LGA775|
|Pentium 4 XE 3.73GHz||3.73GHz||2MB||1066MHz||Late Q4'04|
|Pentium 4 XE 3.46GHz||3.46GHz||1MB||1066MHz||Nov 2004|
|Pentium 4 670||3.80GHz||2MB||800MHz||Q1'05|
|Pentium 4 660||3.60GHz||2MB||800MHz||Q1'05|
|Pentium 4 650||3.40GHz||2MB||800MHz||Q1'05|
|Pentium 4 640||3.20GHz||2MB||800MHz||Q1'05|
|Pentium 4 580J||4.00GHz||1MB||800MHz||Q1'05|
|Pentium 4 570J||3.80GHz||1MB||800MHz||Q4'04|
|Pentium 4 560J||3.60GHz||1MB||800MHz||Q3'04|
|Pentium 4 540J||3.20GHz||1MB||800MHz||Q3'04|
|Pentium 4 530J||3.00GHz||1MB||800MHz||Q3'04|
|Pentium 4 520J||2.80GHz||1MB||800MHz||Q3'04|
Oddly, this feature which we consider one of the strongest advantages of the 6xx processor line goes completely unmentioned aside from a few footnotes in the entire roadmap. Unfortunately, one disadvantage we saw of the processor was the 800MHz front side bus. These chips are slated to launch with the 1066MHz FSB capable Glenwood/Lakeport chipsets, and that gives us little hope that we will see many 1066FSB processor launches in the near future other than Pentium 4 Extreme Edition 3.46 and 3.73. It seems the Pentium 4 720J (Pentium 4 Extreme Edition 3.73) that we mentioned in our previous roadmap update is no longer refered to as Pentium 4 720J. The Pentium 4 580 and 570 have also been pushed back a quarter.
The same cryptic "Smithfield" introduction page was found in this roadmap as well. You can check out the original we published here on AnandTech last month.
The Celeron lineup is also finally launching on the Socket 775 socket as well. The new processors, ranging from model 325 to 350, will begin deployment in a few weeks. Even though the Socket 478 Celeron roadmap continues well into Q2'05, we will only see new Celeron model releases on Socket 775; but as an added bonus all Socket 775 Celerons support the XD/NX bit. We have some future articles discussing the advantage and practicality of XD/NX and we will discuss those more in the future.
|Intel Budget Desktop Lineup LGA775|
|Celeron D 350||3.20GHz||256KB||533MHz||Q1'05|
|Celeron D 345||3.06GHz||256KB||533MHz||Nov 2004|
|Celeron D 340||2.93GHz||256KB||533MHz||Soon|
|Celeron D 335||2.80GHz||256KB||533MHz||Soon|
|Celeron D 330||2.66GHz||256KB||533MHz||Soon|
|Celeron D 325||2.53GHz||256KB||533MHz||Soon|
Finally, we have a few teasers about Lakeport and Glenwood. As we have mentioned in the past, Glenwood (akin to Alderwood; i925) will act as the "high" end Intel core logic. Lakeport (akin to Grantsdale; i915) will assume the lower end position. Details were skimp other than the new chipsets will both support PCIe, 7.1 channel audio, dual channel DDR2-667 and the ICH7 southbridge. 667MHz DDR2 looks extremely unambitious on Intel's behalf; particularly since we have DDR2-667 modules now and promises from SiS, ATI and VIA to deliver DDR2-800 within 6 months. Release dates for Glenwood/Lakeport stand at Q2'05.
More on XD, EIST and Pentium M later in the week!
