Why did Intel stop their Tejas plans, what's behind it all? What will come instead?
Check it out what I found
"Everywhere you look, people are talking about Intels Tejas, the fourth generation pentium 4. In case you forgot, there was Willamette, Northwood, Prescott & Tejas.
Yesterday I pointed out that Intel has cancelled its future plans for the Tejas project and they will now directly shift to dual-core chips.
Lets go back in time. Tejas was originally bound to launch at the end of 2004. Details around the chip were very well known: Tejas would be slapped into a LGA 775 (Land Grid Array). And frequencies would be 4.4Ghz at launch. If we take these speeds seriously, this launch was pretty much doomed to be pushed back until Q1 2005. But that doesnt matter right now. Tejas was also going to be the first CPU to run at 65 nanometers.
So, why did Intel can Tejas? As you might all know, Prescott is a +100 Watt power sucking beast. Tejas would up this amount with 50% bringing it around 150 Watt. This amount of power usage is just not do-able. Intel of course had its solutions to this problem, think of BTX.
Cooling down a +100Watt CPU (no matter if you re using LGA775 or not) is an expensive task, and that s exactly what Intel wants to avoid.
Another problem was the fact the Tejas was a pinless CPU. The effect of this specification was that the Tejas CPU could only be installed once (or at least this was word around the campfire).
Back to the present. Intel stopped the Tejas project and the Xeon project which was based on the Tejas core, once again displaying there mistakes, just like the naming schemes they had to introduce.
If Intel is going to use their mobile technology to make these dual-core chips, and Im sure they will. It s almost for sure they will directly jump to the Dothan core rather than Banias which is used in todays Centrino setups.
A specific Dothan feature is 2MB L2 cache, this would mean the Dual-Core chip will have up to 4MB L2 Cache, can you say impressive?
Of course it s very unlikely all future Dual-Core chips will have up to 4MB L2 cache, some just might. Another aspect that comes into mind when using the mobile technology as desktop tech, is the low power consumption. Im sure Intel will be glad to see their processors run at 40°C rather than 75°C."
