Ace's Hardware has had a little inside look on one of Intel his desktop CPU & chipset roadmaps :

The mass production of the Tejas CPU is targeted for Q4 of 2004. Tejas, the successor of Prescott, has a larger L1-cache (24 / 32 KB according to some rumors) and improved hyperthreading. Tejas is still a "Netburst" or "P4 alike" processor. Nehalem (the next Intel CPU) is based on a new architecture.
Another interesting thing is that most likely Tejas will not be the first LGA 775 (Land Grid Array) CPU. The roadmap indicates a Q2 2004 introduction of the new "Grantsdale-P" chipset which has only support for 775 LGA CPUs. And all our "Intel - inside" sources say that Tejas will arrrive in Q4. This seems to indicate that Prescott, not Tejas, will be the first CPU available as LGA 775 CPU.
Also they have gathered some more information about the Grantsdale, Intel his next big chipset. Grantsdale supports a frontside bus of effective 800MHz and will handle 333MHz and 400MHz DDR, as well as DDR-2 533 (later). Is DDR-2 ever going to take off? I am starting to doubt it. Grantsdale is also the first chipset with PCI Express.
The First Prescott "Celeron" processor will launch in Q2 2004 at 3.06GHz and 2.80GHz with a 533MHz FSB and 256K L2. Seems like a much better deal than the current Celeron to me...
Something suprising that Ace's Hardware found is that Intel his roadmap only indicates a 3.8GHz Prescott in Q3 2004. The Tejas will be launched at approximately 4GHz in Q4 2004, and could reach approximately 4.4GHz at the end of Q1 2005. This is what they think about it :
| | However, this means that since the introduction of the 3.06 GHz Pentium 4 in November 2002, clockspeed will have increased by only 1 GHz at most or only 33% in two years time! Compare this to the speed at which clockspeed has increased the past years. The 1.5 GHz Pentium 4 has been introduced in November 2000, and in November 2002, the clockspeed doubled (3.06 GHz). And we are not even talking about the two years before that period (Nov '98: PII-450 - Nov' 2000: P4 1.5 GHz). It seems that even the process wizards of Intel can not change the fact that Silicon/CMOS technology seems to getting close to it's limits...

Oh well, increasing clockspeed is not the only way to increase speed of processors. Take a look at the Pentium M's for example..
