Yonah , Intel Corp. ’s two-fold - gist roving central processing unit for the first after part of 2006 , is every number as revolutionary as the single - core Pentium M central processor that changed the style Intel designed its chips , fellowship executives said Tuesday at the Intel Developer Forum ( IDF ) .
Tuesday ’s bighearted intelligence at IDF was check of the society ’s architectural plan to base extroverted dual - core C.P.U. for screen background , notebook computer and servers on a common computer architecture inspired by the Pentium M. While much has already been revealed about Yonah , it is basically the rough draft for those french-fried potatoes and a more refined design than the ship’s company ’s first endeavour at dual - heart and soul microcomputer processor .
Yonah is not just two Pentium M cores slap together on the same silicon dice , said Ronny Korner , head of presilicon validation for mobile platforms at Intel . The separate marrow are based on the Pentium M , but they work very closely together to save baron and improve performance by share data and monitor the workload on each core , Korner articulate .
The Pentium D , Intel ’s threefold - core microchip for desktop PCs , was simply two Pentium 4 C.P.U. crammed onto a single chip with minuscule time to overcome problems such as package design and bespeak hitch , an Intel engineer told attender at the Hot Chips league last week . Yonah , on the other mitt , was plan from the source to sweep over some of the challenge of producing chips with two processing cores , Korner say .
Yonah ’s two processor cores each have their own banking company of cache memory , which store frequently used data point close to the principal processor ( key processing unit ) where they can be accessed more quickly than data stored in main retentiveness . Those cores portion out information about the contents of that cache directly with each other , unlike the Pentium D ’s caches , which exchange information by sending a sign out of one inwardness , off the chip , and back onto the chip to the other core .
Intel also plan a deep sleep state for Yonah that reset the cache memory of data in parliamentary law to bring through power , said Mooly Eden , vice president of the Intel Mobile Platforms Group and the leader of the design team that produced the original Pentium M. During extended stop of inactiveness , Yonah saves the contents of the cache memory to the primary computer memory and then shut out off those transistors . remembering command an electrical charge to store data , so Intel can reach even lower levels of power use of goods and services by turning off these transistors , Eden say .
Yonah will squander as much business leader as its single - core predecessor as a resultant role of this and other mightiness - saving features build into the micro chip , Eden said . This is despite the fact that Yonah contains two processor cores and millions of additional transistors , he articulate .
Intel also disclose a number of power - saving technologies work up into the 945 Express chipset and Pro / Wireless 3945ABG check that will accompany Yonah in Napa , a forthcoming program that combines the three . notebook based on Napa will offer longer battery life with a significant increment in performance over older Pentium M notebooks , Eden said .
For example , the 945 chipset will be able to automatically dim a notebook ’s display establish on the amount of power left in the bombardment for widen the lifetime of that charge , Eden say . On the graphics side , the chipset can avoid processing graphic data that does not affect the character of the last image , he said .
Yonah and the entire Napa platform will set up by March of next year . Merom , the notebook chip based on Intel ’s new processor architecture detailed before on Tuesday , will add virtualization , security and 64 - fleck technologies to Intel ’s notebook computer lineup when in arrives in the second one-half of the class , Eden said .
