Intel's Pentium Extreme Edition 955: 65nm, 4 threads and 376M transistors

Intel’s move to their 65nm process has gone extremely well. We’ve had 65nm Presler, Cedar Mill and Yonah samples for the past couple of months now and they have been just as good as final, shipping silicon. Just a couple of months ago we previewed Intel’s 65nm Pentium 4 and showcased their reduction in power consumption as well as took an early look at overclocking potential of the chips.

Intel’s 65nm Pentium 4s will be the last Pentium 4s to come out of Santa Clara and while we’d strongly suggest waiting to upgrade until we’ve seen what Conroe will bring us, there are those that can’t wait another six months, and for those that are building or buying systems today we need to find out if Intel’s 65nm Pentium 4 processors are any more worthwhile than the rather disappointing chips we had at 90nm.

The move to 90nm for Intel was highly anticipated but it could not have been any more disappointing from a performance standpoint. In a since abandoned quest for higher clock speeds, Intel brought us Prescott at 90nm with its 31 stage pipeline - up from 20 stages in the previous generation Pentium 4s. Through some extremely clever and effective engineering, Prescott actually wasn’t any slower than its predecessors, despite the increase in pipeline stages. What Prescott did leave us with however was a much higher power bill. Deeply pipelined processors generally consume a lot more power, and Prescott did just that.

The gaming benchmarks are interesting; very small difference

Another chipset change; another mediocre performance. Should AMD M2 DDR2 shows the same in mediocre performance gain requiring new motherboard, memory and CPU ..... DDR2 sales may well face another disappointing result.

Doesn't AMD include the PCIE controller on the chip with M2?

and DDR2 is currently in short supply

huh ? totally not. There is so much stock that SamSung already lowered the production capacity...

There is so much DDR2 inventory; they have to stop making them

That I have not heard/read, yet.

7th link

If anyone believes DDR2 in short supply, meaning prices will go up = demand exceeding supply = buy in RAM stock.

Manufacturers always adjust production according to inventory level; oversupply = price drop; high demand with low supply = price increase.

Yes, I agree there is some forward looking statements being made. Until the fat lady sings, DDR2 is in abundant supply.

Opteron 165 is in short supply; because there ain't many reseller carry inventory.

did you check the 7th link?

Yes, I did. And I do remember paying $400 for 16MB of memory in 1993.
