What you'll notice with Nehalem is that the more it distances itself from the competition in benchmarks, the more power it will dissipate, because it's getting the work done faster. This is actually what you'd like to see in a processor design, but what I expect to happen is that most reviews will take the most favorable performance benchmarks for Deneb, and then thrash Nehalem in a "CPU Load" ...

Better relative performance of Nehalem vs Opteron I think that the reason why the 2S Nehalem performs equivalently or better than 4S Opterons is the better cache architecture of Nehalem. The inclusive cache leads to a much faster cache coherency response, and obviously the better speed of Quickpath also helps. These facts probably cause the Nehalem to scale much better with multiple sockets than ...

Re: I agree, but I believe Nehalem will do more than just "win" compared to Shanghai. What we've seen so far indicates 2x Shanghai performance per core on more than one workload. That is huge... much bigger than the Harpertown leads. That is what is different. Nehalem ought to have a big lead. It's a better architecture, has more memory bandwidth, faster interconnects, and none of the drawbacks ...

I think the asp rising effect of Wolfdale/Penryn/Nehalem will be greater than the asp lowering effect of Atom as both sets of products ramp. I'm not sure if Q4 will be a good guide as the Recession would have killed that quarter, we need 2 consecutive quarters in the Recession with flat prices spanning them to find who's right.

Nehalem..2x Shangai performance per core on more than one workload I do not recall that the single socket Nehalem outperforming Shangai by that much. The dual socket Nehalem is outperforming or equalling a 4 socket Barcelona/Shanghai. Is the Quickpath link that far superior to AMD HT ? Will a changeover to HT3 by AMD next year dramatically narrow the gap ? Or is the CPU core architecture of ...

Re: We show that Nehalem outperforms Barcelona on memory-intensive codes by a factor of two for a Nehalem node with 8 cores and a Barcelona node containing 16 cores. Further optimizations are possible with Nehalem, including the use of Simultaneous Multithreading, which improves the performance of some applications by up to 50%. Holy crap... this says it all.

Hi, I'm planning on getting a new Intel Core i7 'Nehalem' processor, i know i need to have ddr3 ram, but i've heard that you need to have a certain amount of sticks to make it work correctly? is this true? Thanks for any help. M@

Why wait for the Nehalem Xeons? The single-socket server space has been a niche part of the server space, just as machines with more than four sockets has never been a particularly high volume part of the market. Free Download - The Reg Guide to Storage and Storage Platforms More...

58C...is that load? My 24/7 temps on max load are 70C at 4.2 and 1.376v load. I realized after posting the run in pic, I actually hit 100C, see thermal LOG in red under core 1 on real temp...LOL. That one probably throttled at one point, maybe right at end, but did not affect score, have other runs that did not throttle or hit 100C with same score. I need to open a window and let some cold air...

I figure in February when the DDR3 chips arrive (AM3) that prices will go down a little bit. 4 more chips will be added next month. Lower clocks and lower cache on a couple, but the other couple look just as good as what is already out. I think that these AM2+ chips are just temp, and once these AM3 chips are out, AMD will be lowering the price I would guess almost weekly to filter out ...
