Yorkfield QX9650 (45nm) Sails past 4.25GHz

Intel QX9650 Yorkfield finally comes out - The INQUIRER

The L'inq have gotten hold of a soon to be released intel QX9650, which is the 45nm replacement for the QX6850.

Its a Quad core (2x2) chip with 12MB of l2 cache (2x6mb) a stock fsb of 1333mhz and mult of 9x.
Its the first of the 'penryn' generation chips.

With an asus X38 board they decided to give it a little overclock. They managed to get the chip stable in xp at 4.27GHz whilst keeping all the voltages within the 'green' region in the bios.

Not bad really and just look at the score its posted.
Does AMD have an answer to this chip ? phenom will have to overclock to around 3.5GHz + just to keep up!

And that was under water. No extreme cooling. Amazing. I would love to get a couple of those in a folding farm.

Intel's work on high K has really paid off, given that Penryn wouldn't be possible without it.

It seems the nda has been lifted early since the chips werent due for another 2 weeks, thw (Revamping the Core 2 Architecture – New Flagship: Extreme QX9650 : Intel’s 45nm Penryn Processor – Hitting 4 GHz with Air Cooling) has managed to get a chip past 4GHz on air cooling, it seems the 45nm process and the other tweaks really are running nicely. Then again conroe in dual core form could do 4GHz quite easily though quads did suffer, now they dont!

Does "high K" mean high impedance between layers? As in less wasted current drain? Ergo lower power requirement and less heat?
AMD is nearing irrelevance here. Not good!

Just think, about 7 years ago the fastest CPU Intel had at the time was the P4 2.4Ghz...Amazing, just amazing!!! I can't wait to see what the next 7-10 years are going to bring!

Yup, fully loaded at 3GHz the yorkfield chip uses 47w less than the kentsfield chip for the exact same cpu speed.
Its been reported that even though its a 130w tdp cpu, at stock frequencies its only using 74w fully loaded.
When idle and using speedstep some chips have been measured to be using less than 5w!

Its seeming like intels 45nm process really is somthing special, after the 65nm process saved them from the disaster that was the 90nm process intel has had time to learn from its mistakes at 90nm and has been able to produce really cool running chips that have alot of headroom left in them.

For a 3GHz quad core chip to be easily overclocked by nearly 50% (they're hitting ~4.5GHz) is just amazing, most of the reviewers have said intel could release a 3.66GHz chip today if they wanted to as the new extreme is hitting this speed with just a mult change and no extra fsb or voltage.

The high k dielectric that Intel has is pretty much the reason why Penryn and Silverthorne have been possible. High k plus has resulted in much better performance, as well as lower leakages from transistors. Intel started researching high k materials in the late 1990s... That's a long time to be doing R&D.

However, how well will high k dielectrics work on 32nm, 22nm or 16nm processes? No-one knows that answer yet.

Yeah, I remember there was a lot of discussion about High-K versus SOI. IBM and that lot felt that SOI was the better near-term bet, but Intel felt that high-k was the way to go, IIRC.

SOI was the cat's pyjamas way back when. Who knew it would be surpassed by the 'other Big Blue?' These 45nm processors are amazing. AMD simply doesn't have the resources for massive R&D and a "lucky guess" seems unlikely. Argh.

AMD-IBM have their own hafnium based high k dielectric. A number of semiconductor firms have been working on the same problem, albeit independently of each other. It's just that Intel happens to have hit the market first.
