Intel "Penryn" Xeon DP to start out at $177 and top out at $1,172

Intel’s latest roadmap reveals pricing for its upcoming Penryn-based Xeon DP processors. Yesterday, DailyTech unveiled the Xeon DP models set for launch.  The costs of entry for Penryn-based Xeon DP processors start at $177 and top out at $1,172.

Intel has two Penryn-based quad-core Xeon DP processors under $300. The quad-core Xeon DP E5405 starts out at $209. The $209 price tag yields a quad-core Xeon DP processor clocked in the 2.0 GHz range, but below 2.33 GHz, with 12MB of L2 cache. Putting forth an extra $47 gets you the quad-core Xeon DP E5410 with its 2.33 GHz clock speed.

As the clock speed increases, the price gaps between quad-core Xeon models get larger. Intel prices the 2.50 GHz quad-core Xeon DP E5420 at $316. Stepping up to the next speed-bin comes at a $139 cost, for the 2.66 GHz quad-core Xeon E5430. The quad-core Xeon DP E5440 and its 2.83 GHz clock speed comes in at $690 -- $235 more than the E5430 with a 170 MHz lower clock speed.

Breaking 3.0 GHz will cost $851 for the quad-core Xeon DP E5450 with its 3.0 GHz clock speed. The quad-core Xeon DP E5450 is as high as the Penryn-based Xeon lineup will go, while retaining an 80-watt thermal envelope. If 3.0 GHz is not enough, $1,172 will get you the big daddy of the Penryn-based lineup, the quad-core Xeon DP X5460. The quad-core Xeon DP X5460 has a 3.16 GHz clock speed, but the high clock speed comes at a cost. Intel rates the quad-core Xeon DP X5460 with a 120-watt TDP – 40-watts higher than the rest of the lineup.

If the 80-watt thermal ratings are a bit high, Intel has low voltage quad-core Xeon DP processors. The quad-core Xeon DP L5430 and L5410 cost $519 and $320, respectively. The low voltage processors have 50-watt TDP ratings and command an extra $64 over its 80-watt counterparts.

Intel only has two Penryn-based dual-core Xeon DP processors this time around. The two dual-core Xeon DP processors occupy the very bottom and the very top of the Penryn-based Xeon DP lineup, in terms of clock speed. The clock-topping 3.33 GHz dual-core Xeon DP E5260 costs $851 while the 1.86 GHz E5205 costs $177.

Expect Intel to introduce quad-core Xeon DP processors next quarter in normal and low voltage flavors. The dual-core Xeon DP processors are not Penryn launch products, but will arrive in Q1’08.

Concerning a quad-core.

Isnt the number of manufactured cores always based on an Even number? 1 isnt, but it doesnt have to match itself with anything else.

If you have 2 cores on this side of the boat, and 2 cores on the other, and one falls overboard, would'nt that mess up everything?

I would believe that would definately create some inconsistencies in processing.

The XBox 360's CPU is a tri-core.

It doesn't get bigger because they can change the architecture to optimize them and also decreases in manufacturing size. 130nm -> 90nm -> 65nm -> 45nm -> etc etc. That's almost 3 times smaller than the early AMD Athlon 64 chips were created on so you could easily pack many times more transistors in the same space.

You'd think it's around three times smaller but it's actually closer to 8. Each full node change halves transistor size, I'm not sure why though.

That's why dual worked with 90nm and now quad works with 65nm. If Penryn was a native quad chip, Intel could easily put two on one package and make an octo core.

I believe it's because when thinking about chip size you have to think in terms of area. So the effect of each process shrink is squared...For example if a chip on 90nm process is 9cm by 9cm, the area for this chip is 9^2=81cm^2, when we move to 65nm, the same logic can (ideally) fit in 6.5cm by 6.5cm, and the area of this is 6.5^2=42.25cm^2. So now we can have (81-42.25) 38.73cm^2, almost half, of the area on our chip to add more logic, or we can shrink the chip size down and save on cost.

Of course, the shrinking of the area will not work exactly as mentioned above as that situation is the ideal. Some logic does not scale down as well others and we may not have as much free space or be able to shrink quite as might be expected, but this is still the general idea behind it.

Yup. You are correct.
And the shrink from 65 to 45 is even better since 65^2/45^2=2.09 and 90^2/65^2=1.91 - quite a respectable difference.
There are, however, certain key points in the IC that are not manufactured at the lowest dimensions available. Still, they can usually be shrunk anyway since, there were key points on the previous process anyway. Ex: when manufacturing a certain IC in 65nm some key transistors are kept at 90nm, but once the process is moved to 45, those parts are reduced to 65nm.

That does seem logical...everything for computers should come in powers of 2!

Can't make them faster? Add more of them!

Although the idea seems pretty simple, I think the implementation must be fairly complicated. Getting the cores to communicate and share data efficiently would be very complex. I don't even want to think about all the possible data and branch hazards involved with multi-core, multi-issue pipelined processors!

Why did I get voted down for that? Was it something to do with the word 'cheating' ?

I'm not an expert in the hardware in that particular domain, but I can't imagine that they couldn't produce a tri-core processor. The geometry of the chip might be nicer with 1, 2, or 4 cores, but I doubt that can't be overcome.

Certainly the software wouldn't care if there were 3 cores.


Where's Tigerton?

Except for the press releases last year, we have yet to see any Xeon MP (greater than 2 sockets) C2D based chips announced...
Does this meen that Intel is leaving the enterprise boxes to Barcelona alone?

Tigerton will be released in September. As been mentioned by Dailytech and other sites.
