Intel Core 2 Extreme QX6850
The Core 2 Extreme QX6850 is now the new flagship of Intel CPUs with four cores and not only enjoy an increased bus, but the core rate was slightly increased. In direct comparison to the QX6800, based on the current B3-stepping Kentsfield-based, the QX6850 now works with 3.0 GHz (333 MHz x 9) and relies on the refurbished G0-stepping. At the previous architecture, the caches and the features it has not changed and is based on proven technology.
Intel turned in its quad-core series Turbo: The commercially available today in the Model Core 2 Extreme QX6850 Intel operates with a higher front side bus. Instead, the 266 system clock is now 333 (effective 1333) MHz. At the same time, Intel underlines the working frequency slightly to 3 GHz now - the strongest yet tactful quad-core model, the Core 2 Extreme QX6800, runs at 2.93 GHz. Otherwise, everything remains the same: The Core 2 Extreme QX6850 consists of two de facto Core 2 Duo E6850, the semiconductor giant in a processor has packed housing. Overall, the QX6850 8 MB of L2 cache available.
The maximum power dissipation (Thermal Design Power) is, according to manufacturer’s specifications at 130 watts - for a four-core CPU is a good value. In addition, the Intel Core 2 Extreme QX6850 all important functions spendiert that a modern processor should dominate. These include hardware virtualization, the 64-bit support and various additional instruction sets to SSE3. And in an Extreme variant may also not arbitrary multiplier of the missing - who for better cooling provides, can the 3-GHz processor so very easily elicit more power.
