Reviews Word on the street for the Intel Core2 QX6850


8.0
Bumping up quad-core to the new 1333MHz FSB in the Core 2 Extreme QX6850 seems to boost performance, even with DDR2 memory; the price, though high, now seems rational.

8.0
The secret is the new G0 stepping, which increases frequency potential, reduces power consumption and improves heat dissipation.

Overall

8.3 Out of 10

What People Are Saying Give it to me straight

Socket Type

Today, we'll take a look at the new high-end Intel CPU, the Core 2 Extreme QX6850, which now logically fits into Intel's product line, unlike the earlier QX6800, which seemed to be an outlier in more ways than its lack of DDR3 support.

Ever since launching its Core 2 microprocessors in July, 2006, the Santa Clara company has maintained a steady pace, with new Core 2 introductions occurring every few months.

It's still the Kentsfield core, but an FSB raised to 1333MHz bumps the clock to 3GHz.

Multicore

Fastest desktop quad-core CPU you can buy today.

Temperature

The crazy nitrogen-cooling contingent have already taken this chip past 5GHz.

Applications

Some apps see little gain.
