Thread: Core ii Extreme QX6800

Not message with already having the most strong desktop central processing unit on the market in its Core ii Extreme QX6700, Intel has freed the QX6800, which is a quad-core central processing unit with a 2.93GHz clock velocity. This is 333MHz quicker than the QX6700 and will befit someone who requires more grunt for taxing apps such as video altering, encoding or picture manipulation.


The Core 2 Extreme QX6800 retains the similar Core ii micro-architecture as the QX6700 and has the similar quantity of cache and front side bus velocity (1066MHz, which is 266MHz, multiplied through the four data bits that the Core 2 can process within one clock cycle). It is essentially 2 double-core Core ii Extreme X6800 central processing units in one package and every double-core part of the QX6800 shares a basic iv MB of cache. Thus, not entire cores have access to the similar fields of cache. Theoretically, this can potentially lead to latency trouble, but our tries did not show any show of this being a trouble when utilizing basic applications.


Trying with World Bench Six below Windows Vista Ultimate, utilizing an ASUS PFiveB Premium CPU board, One gigabyte of 800MHz DDRii random access memory, a Western digital 500 gigabyte hard drive, an ATI Radeon HD 2900 XT graphics board and a Seasonic energy supply, the QX6800 demonstrated an entire improvement of without then 5% finish the QX6700 -- 105, equated to 102 for the QX6700.




Entire, this World Bench 6 answers is not anything to boast about, but the single application scores within the benchmark depicts nice increases in the compression, encoding and rendering parts of the try. The 3ds Max 3-D rendering try, for example, was finished 25sec faster through the QX6800, when the Windows Media Encoder 9.0 tries was finished 11sec faster. The Roxio Videowave encoder try was finished 10sec faster and the WinZip compression try was completed 8 seconds quicker. This is, of course, due to the additional velocity that the QX6800 has finish the QX6700.


It was too a profit in our MP3 encoding try, utilizing iTunes, where it encoded 53min valuable of WAV files to 56Kbps MPiii documents one second faster than the QX6700, and too in the Sorenson Squeeze try, where it encoded a 3min 42sec MPEG documents to a Quick time document desirable for consumption finish a 512Kbps Internet connection, 5 seconds faster than the QX6700.


When the function increases are not prominent, similar to the QX6700, the QX6800 can be overclocked, which intends that much excellent increase can be acquire. Utilizing a clock multiplier of 13 and a front side bus velocity of 266MHz, we tried the QX6800 reliably at 3.47GHz. Our iTunes MPiii encoding try showed a marked development at this velocity -- it competed the try in only 36sec; the default 2.93GHz velocity assumed 43sec. The Sorenson Squeeze try completed in only 46sec at the 3.47GHz velocity, which is development of 5 seconds over the 2.93GHz default velocity.
