Pentium 5... Nehalem

[daba]

I've heard and read so many things about the Pentium V processor... some that it would be based off the Pentium M chip, that it will be around the neighborhood of 4-7GHz (up to 10.20GHz as a matter of fact), and others on the completely opposite side saying that it would be at a lower clockspeed but have higher performance.

Anyone have any comments to add to support or reliquinsh these rumors?

Wasn't P5 Tejas which was just cancelled due to heat output and power consumption and Intel focussing on Dual Core chips? <_<..

The Tejas was supposed to be the succesor of the Prescott and thus probably the Pentium 5. The "new" Pentium will probably be double-core, Dothan-based.

still begs the question of what happend to Nehalem, you think Intel would of said something

 

[bgeh]

Nehalem was supposedly the successor of the Tejas, but now i think it's also dead

yeah, they did say nehalem would hit 10.25Ghz by 2005, this was around the time Intel were bringing new speeds bumps to the p4 every 2 months or so in 200 Mhz jumps, when things were really flying along, the northwood was great core for scalling, but as you'v seen theres trouble ahead.

we may not know if Nehalem is still going ahead but Im pretty sure it safe to say there wont be a 10.25Ghz Intel CPU out by 05, 6Ghz at the most, unless Intel pull a mriacle off.

Another thing to bear in mind, although 10Ghz sounds great, Inetl kept having to increase the number of pipelines to scale, devaluing Mhz along the way or lowering IPC's, so its hard to tell if performance really is increasing to amazing levels.

High IPC'S, less number of pipelines seems the better way to go, AMD's way, only trouble is getting the things above 2.5Ghz on a 0.13 micron process, hopefully 90nm will create far more headroom for clock speed.

 

[VIAN]

I remember Intel saying that they are moving away from clock speed and focus on other ways to increase speed.

 

[Stoneburner]

Intel has increased its mhz by 200 in 1 year

WHy doesn't AMD just release the 3800/3700 and blow Intel out the frame?

 

[clarkey01]

cos the 939's arnt ready yet. AMD only has Dresden as there main FAB, Intel has around 8 i recall, maybe its not capacity, maybe AMD is just watchin Intel, seeing how badly wounded they are

plus another reason is scalling, i think they cant hit much over 2.6ghz on 0.13 micron process, hence the need for 90 nm.

proubly a little of both. amd sees it had sometime to get the switch to 90nm right so its taking its time making the switch while intel regroups.

I would like to see Paris make its debute soon I would love a 2500 rated processor based on the A64 core without 64bit. would make a good budget chip and allow amd to switch all its production over to the Athlon 64 instead of both XP and 64

Exactly and Intel was doing this prior to the A64 release and the p4cs had pushed by and were pulling away from the Bartons...They could have easily released a 3.4ghz northwood then....Doesn't make business sense....Why would a company want to further the lead and drop their already top performer chip in price when the can keep it at the other price, keep the crown, and profit more??? Business 101 ppl....

 

[clarkey01]

Perhaps Intel could have droped a 3.4Ghz Northwood on AMD early, AMD wouldnt have known what to do, there XP struggles against the 3.2 at 2.2, and the Xp cant really be pushed any further then 2.3Ghz, so Intel would of had a huge PR victory of they did.

Prescott (dont get me started)

Back to nehalem

10.25Ghz by 2005 ? ......No chance

well its obvious with what the mobile xps are doing amd could of released a 3400 and 3600 athlon xp but didn't to keep it from competing with the 64

 

[clarkey01]

maybe its different with mobiles, but im pretty sure AMD were scraping at 2.2Ghz for the 3200xp, i like AMD, more so then Intel, but I feel that the 3200 doesnt compete with a 3.2Ghz P4c

10 Ghz??? There's static material properties of silicone which make that difficult if not impossible barrier even with technology and manufacturing improvments. I heard something along these lines from an intel engineer Bob Colwell a few years back. I'll see if I can find it but basically the power requirments are dimisihing returnes on a semiconductor like silicone since it acts as a worse semiconductor with increases speeds because the heat generated by higher voltages needed to overcome the potential diference of the material. We would need 300W chips or better. This is why intel is wising up and going AMD way for more speed.

This is up there with faster than light travel and colonizing Alpha Centari's planets. Good for Scifi and art bell but not based on physical realities of the universe.

 

[clarkey01]

10Ghz in 5 years i reckon

Tejas may be cancelled, but Nehalem was supposed to be a different architecture, so we can't take out the possibility that Nehalem is still there. Couple of hints is http://www.x86-secret.com/ go to the article in the main page that says Abandon du Tejas : Oui mais... and read the last one or two paragraph. I don't speak French but I used Altavista's language translator(Link: http://babelfish.altavista.com/). Which said Nehalem will be the 2006 successor to Prescott. Link that suggests Nehalem may have some of Banias/Dothan technology. Link: http://www.geek.com/procspec/intel/nehalem.htm
Although I don't know the credibility of the two sites, I also heard it somewhere else, and since Nehalem is supposed to be a new architecture, it may not be cancelled. Just probably not at 10GHz. Anyway I think when they say 10GHz, they are actually referring to the maximum speed in its lifespan, even though it says it otherwise.
