Qx9650 vs Qx6850

[Microcooler]

hi

I am looking to buy new Intel processor so i searched for quad-core processor where i found Qx9650 is good. now my friend having Qx6850 which is better in performance so i am confuse in both that which one will be better to buy ? please help me .
thank you

QX9650 family is with core Yorkfield Penryn .The new CPU is manufactured with the 45nm process 214mm die extent and within 820 million transistors.The Quad core with the Kentsfield QX6850 has a die with an area of 282mm with 582 million transistors.

The amount of second level cache for the QX9650 is a 12MB, against the Kentsfield also 8Mb cache of Yorkfield and type 24 way associative, while for the Kentsfield and the type is 16 way associative. Intel introduced a new set of instructions SSE4 which help to speed up video encoding, of course, if supported by the software, were also improved the energy saving features inside the cpu, but that should be supported the bios of the mainboard. Qx9650 consumes far less heat and is much easier to overclock.

In practice, the gain is variable with DivX Encoder 6.7 yet sensible take advantage of SSE4 and therefore show a big gain just faster to compress the video with the Penryn. The largest gains are in the active compression multimedia applications, except that neither LA nor Win Main Concept H.264 currently does not take advantage of the new instruction set. Divisions is twice faster with SSE Shuffle and therefore explain alone these significant gains. In games Qx9650 performance is also highly variable.
