Intel Tejas processor and socket images

How many pins Weta?

and yes thats the a new processor in progress from Intel.

[amd_man2005]

ITs 775, and I believe theyre CONTACT like deals, that just touch the socket, not actual pins

[Rage]

weta, is that a new processor from Intel?

The Tejas is the successor to the upcomming Prescott from Intel. It is widely believed that the first iteration of the Prescot will be in the current P4 socket, with a pinless socket to come Q2 next year.

Prescott:

- 90nm process
- 13 New instructions
- 1MB L2 Cache
- 800mhz Front side bus
- Works with canterwood and springdale*

* But perhaps not current 875 and 865 boards due to voltage requirements. ASUS recently removed the Prescott compatability claim from their website.

Cheers, Tom.

So in other words if I buy a nice 865 mobo next month I'll probably have to replace it Q2 2004 if I want to get me one of those new fancy cpu's with 1Mb L2 cache.. Or does anyone know if any brands will unlike Asus keep their claim about compability with this new cpu's..:?:
A new mobo isn't the hole world to replace though, after all their not that expensive..

:cheers:

From the looks of hte CPU, an upgrade will be required motherboard wise.

If you want one of the first iterations of the prescott, you'll have to upgrade later this year. New pinless socket is comming next year.

IIRC the reason for the new boards is different power regulation requirements. I think the 875 and 865 chipsets already support the Prescott.

I am gonna call bs on the 4000mhz FSB speed. There is no way we will have memory that runs that fast to keep up with it. There are other limitations as well.

Intel Tejas & socket 775 unveiled

<img src="http://images.tweaktown.com/weta/intel/tejas.jpg">

While the majority of the AnandTech staff were hard at work in Las Vegas covering CES, a quiet staff member was touring the streets of Taipei.

During his visit to Taipei he came across some information shared by some very good contacts about Intel's Prescott successor - Tejas. Very few people caught on to the fact that we actually talked about Tejas on AnandTech years ago as we heard about the codename before Prescott and even before Northwood, hidden in an Intel presentation that hadn't properly been cleaned up. Originally Tejas was listed as the first Intel CPU to have a 1.2GHz FSB, but now we know a bit more about the CPU.

Apparently a total of 10 Tejas samples have been shipped out to various friends of Intel, all running at 2.8GHz. What's also interesting to note is that our sources have informed us that at 2.8GHz Tejas uses around 150W of power - about 50% more than Prescott at the same clock speed.

Given that Tejas is still a 90nm part, it would be unlikely that the additional power consumption would be due to a larger cache as that would make the die huge and isn't Intel's style to increase cache size without shrinking the die further. If the power figures we've been given are indeed correct, one possible explanation would be that Tejas is indeed some variation of a multicore CPU. While it is unlikely that Tejas includes two discreet Prescott cores on die, there is a chance that the two cores (if they exist) could be sharing data caches and maybe other units. A multicore Tejas would explain the jump in power consumption, and it is in line with Intel's strategy although it does seem sooner than expected.

The 10 Tejas samples are all LGA-775 CPUs and luckily our contact was able to gather some pictures of the CPU and the interface so you all can get a glimpse of what is soon to come. We had to blur out some parts of the pictures to protect the identity of our sources, but you'll still be able to see what's important.
