Intel is to release future cpu “Nehalem” in Q4 2008

October 26, 2007

Intel has just announced its plans to release its new Nehalem cpu architecture in the fourth quarter of next year. The new cpu will require a new motherboard chipset dubbed the LGA1366, all people currently sporting the intel 775 chipset ranging from certain celerons all the way to core 2 quad cpu’s, a new motherboard will be necessary for future upgrades. The biggest new feature of the Nehalem architecture is an integrated memory controller on die, this has been a feature on amd64 cpu’s since 2003, and helped amd win the performance battle of that time period. It will be very interesting to see how future intel cpu’s run and overclock without the aging front side bus architecture. Another interesting fact about Nehalem is that will support hyper-threading, meaning a qaudcore Nehalem cpu will appear to be an octal core within operating systems. Intel is also cutting back the cache 33% in Nehalem from the soon to be released Penryn 45nm qaudcore cpu’s, going from 12MB, down to 8MB. Having less cache is not a problem with an Integrated Memory Controller, the large amount of cache in current core 2 duos does a good job at minimizing the effects of having system data transfered via front side bus, take front side bus out of the equation and less cache is needed as the system latency reduces greatly, look at amd64 for proof of that concept. We already know that the soon to be released Penryn cpu’s which will replace the existing Conroe cpu’s (both core 2 duo), will give an additional 5% to 10% performance gain, I believe we will see very large performance gains in a year, when Intel transitions from Penryn to Nehalem. These are exciting times indeed.

  1. im normally bumping on the online world virtually all of the time so I have a propensity to peruse significantly, which is not commonly a good matter as the largest part of the web pages I find are made up of unproductive trash copied from many other websites a thousand times, on the other hand I have to give you credit this site is honestly half decent and delivers a lot of original content, for that reason cheers for breaking up the trend of only copying other individual’s sites, if you ever want to have fun with playing a couple of hands of myspace poker together just send me a message – you have my e-mail 🙂

    So basically, learn what you can from the books, Academy etc.
