Someone who knows please sum it up lol...This is the new mobile chip right?

And Tejas was completly scraped and there going to a new chip...anything else Intel wants to change? lol

yes this is the new chip, its got 2mb l2 cache...

Not to mention, a shorter pipeline too&#33; [/b][/quote]
Ah, no. The Doh&#33;than chip has the same overlong pipeline as the P4, which is why it needs the 2MB L2 cache.

Looks like a p3

[atiVidia]

whats the pin count?

Uh huh...okay?

The Dothan has a SHORTER pipeline than the Prescott&#33;

You said:

Obviously you are confused.
Dothan IS the Pentium M&#33;

Advanced Technology Maximizes Mobile Performance and Productivity
Formerly codenamed Dothan, the Intel Pentium M processors 735, 745 and 7553 are built on Intel&#39;s industry-leading, high-volume 90nm manufacturing process technology - the most advanced semiconductor manufacturing process in the industry. The 90 nm process produces smaller, faster transistors and uses Intel&#39;s strained silicon technology to give its transistors a speed boost, resulting in higher performance headroom. Intel is the first in the industry to put strained silicon into production and all of Intel&#39;s 90-nm products are manufactured on 300-mm wafers, which provide more than double the capacity of the earlier 200-mm wafers.

Man why don&#39;t you just admit you are WRONG?

Uh... Dothan is a Pentium M. It&#39;s the latest core in the Pentium M series; the previous core was called Banias and was also a Pentium M.

The Banias/Dothan chips are a compeletly different design than the Pentium 4. The operate at lower voltages thus they generate less heat. The pipeline of the Banias/Dothan CPUs is also significantly shorter than the Pentium Northwood OR Prescott variants.

My point is that Intel made a wise move to develop dual core processors based on this new design.

You get your first dose of Intel&#39;s close guarded nature in regards to Banias with the talk of its integer/floating point pipelines. The chip itself has a longer pipeline than the Pentium III, but a shorter pipeline than the Pentium 4. The reason for this is simple; the Pentium III&#39;s architecture ended up topping out at just above 1.20GHz on a 0.13-micron process, but in order for Banias to fulfill Intel&#39;s desires for a high performing mobile CPU, they would need a higher clock speed. At the same time, remember our earlier discussion about the Pentium 4&#39;s pipeline being too long for the good of a mobile CPU. The end result? Something in between the Pentium III&#39;s 10-stage pipeline and the Pentium 4&#39;s 20-stage pipeline.

If you&#39;ve read every word we&#39;ve written about Centrino and the technology behind it and are impressed, then you haven&#39;t seen anything yet. The architecture and technology behind the platform goes far beyond what we&#39;re able to print, but the main point to convey is that the Pentium-M is not a Pentium III and not a Pentium 4, it&#39;s something very new and very different.

The approach Intel undertook with the Pentium-M is one that would be difficult for their competition (mainly AMD) to duplicate. It requires dedicating an entire design team to a project that will be taking significant risks and will be relying on perfect execution on the manufacturing side of things to meet product cycles. The sort of commitment Intel made with the Banias project required an incredible amount of resources, and put those resources at very high risk of being lost should anything have gone wrong. Maybe it was the passion that was burning within the hearts of the Israel design team or the desire to show Intel corporate what the team was capable of, but Banias was the first and only chip in Intel&#39;s history that was no more than 8 days late.

The future of the chip is also quite bright; there are a few tweaks that didn&#39;t make it into Banias that will be present in its 90nm successor known as Dothan by the end of this year. Dothan should be able to ramp frequencies up even higher, while providing an even larger 2MB L2 cache as has been leaked previously.
