Tejas dead, Intel going "dual processors in one chip ca

[DennyA]

Well, this is an interesting turn of events.

Looks like I'm no longer on top of things in the CPU world. :cry:

What on earth is/was Tejas? I never even recalled Intel announce that model. And that new double-core CPU? Are those 32-bit models, or codenames for the new Athlon-compatible 64-bit CPU?

[Woolen Horde]

Tejas was going to be the next desktop Pentium 4.

Most people aren't aware of this, but Intel produces two drastically different Pentium 4.

1. The "regular" Pentium 4.

2. The mobile Pentium 4.

The mobile uses a different core to achieve low-power and low-heat. in essence, it's a much more efficient core.

Now Intel has hit a brick wall with the desktop P4 in terms of heat disappation and power consumption. Notice how we've barely sped up in terms of processor speed the past 18 months?

So what they're doing is essentially phasing out the regular P4 core, and replacing their entire line with the mobile core. And since the mobile core is sosmall, they're going to start putting dual cores on their chips (which is another way to speed up the CPU without adding heat), as well as integrate the AMD64 instructions.

[Chris Nahr]

Ah, so Tejas was based on the mobile core? Thanks, I was aware that they had two lines but I didn't know they were about to merge them.

No, I think he's saying the Tejas was to be the successor to the non-mobile core. The new dual core being planned is built off the mobile core.

And this is all part of the mobile suite gundam?

I don't think that the mobile Pentium 4 has a different core, the core they are talking about is the one from the Pentium M. This core was developed from the P6 (PPro-PIII) with the intention to reduce power consumption. Since this core became a surprising success also in terms of performance it's not surprising that they will concentrate on it rather than the Pentium 4.

The mobile chip that's doing so well is the Pentium-M, not the mobile P4. The mobile Pentium 4 is just a P4 that generates a little less heat.

The Pentium-M core was designed by Intel's Israel architecture lab. The Pentium-M has a big cache (1MB), low power utilization, efficient branch prediction and a relatively small die size. It's similar to the old PIII, but also has some key P4 traits, like SSE/SSE2.

Screw all that. This is the future: http://www.cs.utexas.edu/users/cart/trips
At least it might be if they pull it off.

[Brad Grenz]

Intel's marketing dept can't be happy with this. They're going to have their work cut out for them reeducating consumers that, as it turns out, clockspeed ain't everything.

[Ibbz]

Hency why their introducing a new rating system. The dothan chip I believe is supposed to be the first chip with the new ratings.

As long as Amuro stops crying, sure.

[Cool Breeze]

I'm glad Intel are going back to an architecture similar to a PPro/III. The leap from Pentium to Pentium Pro or a Pentium III was astronomical.

The leap from Pentium III to P4... not so astronomical. It just seemed like the performance gain wasn't quite... there. In comparison to hard drive speeds/performance, GPU speeds, ram speeds, etcetera, the P4 just seemed to flop along like some sort of retarded mutant trout that eventually winds up in the mouth of the bear at the end of its thousand-mile journey because its ambition widely outweighed its true talent. (Yes, you're welcome, I've fulfilled your Brian Koontz-esque simile quota for the day.)

Like that same trout, the P4 was just on a trip that ended very, very badly.

I don't think the trip ended badly, the design has been very successful for Intel and has made them a lot of money, and it also helped them to regain some of the marketshare that was lost to the Athlon. I don't see why you would say that the difference between Pentium and Pentium Pro was astronomical but PIII->P4 was not. The fastest P4 is clearly a lot faster than the fastest PIII, just as the fastest PPro was faster than the fastest Pentium. And do you honestly mean that perfomance improvements of the P4 sucked compared to the improvements in hard drive speeds?

[Cool Breeze]

I said it simply felt a lot faster. I know that the P4 is part of what enables me to run all these astronomically complex games with highly detailed graphics smooth as glass just as I know that it is the P4 that allows me to boot up in thirty-seven seconds instead of ninety-four.

At the same time, it still feels a hell of a lot slower when in comparison to the leap from PPro to PIII. Going from a PPro to a PIII was going from Dungeon Keeper to Warcraft III; from Dark Forces to Jedi Outcast; from Hexen II to Quake III. To me, these were all massive leaps and they felt just as massive as they looked.

I honestly don't know what it is. It is probably me but I know I'm not the only one. With all these improvements, not just in processor speed, my computer sure as hell doesn't feel all that faster.

Shouldn't I be able to access the metaverse by now?

That was two generations of processors.

But I know what you mean. That's why this mad rush to have the fastest processor available is plain silly... processor speed exploded a couple years ago, but software didn't get more complex proportionately. Look at the sysreqs for most new games coming out. Hell, Guild Wars (shipping this October) only requires an 800mhz system.... less than one fourth of the highest clock speed now available in a desktop processor. So that's why you don't notice as much of a speed increase when you go from a 1 ghz P3 to a 2ghz P4... the 1ghz P3 could already run most of what's out there.

That said, the P4 is a much, much better processor than the P3. The P3 was actually terrible... I'm a dyed-in-the-wool AMD guy, but do you remember when the original Athlons came out? They destroyed the P3. These days, they're pretty comparable. The P3 was an overall bad design that was allowed because there was no serious competition.

[cyborg]

I seem to recall that there was a bug in the P3 with regards to floating point operations. Or was that the P2?

Either way people seem to have forgotten the crapness that was the processor ID that was going to make Internet transactions secure and the furour that surrounded it.

That was every generation of Pentium. Except maybe P4, I guess.

I know I haven't. One more thing that made the P3 a festering hunk of shit.

That was the original Pentium 1's, and was only the first two processor's they ran (66 and 75 I believe, it's been a while).

Edit: well, was partially wrong, was all the procs from 60 - 100Mhz - http://www.intel.com/support/processors/pentium/fdiv/index.htm

Shit, now I've got to buy something else. OCD time.

[Aleck]

Can anyone comment on whether the new CPUs based off the Pentium-M will include hyperthreading? (do the current Pentium-M chips include hyperthreading?)
