Pentium V ?

And if you look at the how they scale their bus...800 MHz bus is used for a 3.06 GHz processor, right?

That's about a 3.75x scale (slightly more). Even if they decide to make the scale 3x, then we're talking 12 GHz processors.

A 4 GHz processor is reasonable next year--not a 4 GHz bus, though. I really doubt we're going to see a 1:1 bus-processor ratio.

I agree, that bus speed is absolutely ridiculous even if Intel integrates a PCI-Express based fsb (which is unlikely considering Intel will no longer be able to charge third party chipset vendors for P4 bus licensing ). Perhaps we'll see bus speeds near that figure when Teja's sucessor arrives.

On a technical side note, the Pentium 4's fsb isn't actually a 800 MHz bus, it's a 200 mhz bus thats quad pumped meaning it sends data four times per clock cycle (effectively giving it the equivalent data transfer rate of a 800 MHz bus). The multiplier that determines the core clock speed would therefore still be determined by a 200 MHz bus. Assuming Tejas utilizes a quad pumped fsb as well, we would get a fsb that runs at 1 GHz and 5x-7x multipliers. Still, I seriously doubt we'll be seeing bus speeds anywhere near 4 GHz by the time Tejas arrives.

Yeah that P5 is absurd it really seems unlikely.

I mean really unlikely...

A Bus that is quad pumped from 1 GHZ?

Not really that extravagent given the timespan, Intel's current 130 nm process Pentium 4 Extreme CPUs already have a 2MB on-die L3 cache (along with 512K L2 cache) and are still priced at around $700. Moving to a 90nm process/ decreasing the die size, would invariably decrease the manufacturing cost further.

That chip (Xeon 2.4GHZ + 2MB L3 Cache) sells for $3,692 in quantities of 1,000.

Not exactly 700 dollars.

Not $700 but not 300 either.

The 3 GHZ P4's Start at $300 and only go up:

533 MHZ buses aren't exactly going to be used in the EE P4. According to the cited article, P4EE is just a re-branded Xeon with L3 with an 800MHZ bus. If it does sell at 700 with the same features, at a higher clock speed, and at the same process (130nm) at least we can see how big the margins are for intel on the high end....

That chip isn't exactly the P4EE now is it?

The Xeon MP and Pentium 4EE belong to two different markets with different interests in mind and thus are not going to be priced similarly. As you can see in the link below, the Pentium 4EE is priced at slightly more than $800, which is far below that $3692 figure.

Well, like I said above, we can see how big thier margins are on the high end. Come to think about it, at those prices, why would anyone get a Xeon, other than the ability to go dual?

There are two different kinds of Xeons, the Xeon MP, and the Xeon DP. The Xeon MP is the most expensive of the two and the one you were referring to in your pricing. It's primarily used in medium to large servers where cpu price and performance is generally less of a concern to things such as scalability and reliability.

The Xeon DP is alot cheaper than the Xeon MP and in fact, somewhat comparable to the Pentium 4 (~$500 for a 3.06 GHz Xeon versus ~$400 for a 3.0 GHz P4). This would be the cpu you are currently referring to (in having only dual processor capability) and the price disparity is alot smaller.

I see. Thanks.
What is the difference between the two, besides being MP capable and one only dual capable? Why the big price difference?

Not much, not much at all, the Xeon MP will be slightly more expensive to produce due to it's larger die size (from the 2 mb L3 cache) but most of the price disparity is attributed to market and competition. Whereas the Opteron and Athlon FX pose significant threats to Xeon DP and Pentium 4 marketshares. The Xeon MP remains largely unchallenged in the server market, largely due to the fact that not many vendors are willing to produce and sell Opteron based servers.

Yea, Its pretty bad when people (average person/business) don't care that something that is cheaper, faster, and practically 100% compatible with what they have already have (x86)... largely ignorance I guess? Or stubbornness maybe...

Its already difficult for AMD/Linux, I can't image how hard it must be to compete for Apple....

 

[Brundlefly]

I was reading in an article in business week they wouldnt be releasing it until early 2005, as they figure the 64 bit thing isnt up to snuff yet....

and the P4 has lots of upgradability left in its architecture.....I guess now til 5 gigahertz...

in this time AMD will surpass them, me thinks....and the dual apple G5 3gig....

I am really never processor bound now....I think I will start to live as a last generation man.

"Tejas"

5 to 7 GHz... Wow.

You know, "Tejas" in Sanskrit means "heat."

Probably just an unfortunate coincidence.

 

[yamabushi]

As the rivalry between IBM and Intel gets more heated, I hope IBM dumps Intel for all of their new systems in favor of AMD. I might even buy an IBM AMD based desktop to celebrate the occasion.
