We received from Intel a Core 2 Extreme QX6850 engineering sample, which is now the most high-end desktop CPU available on the market today, featuring four cores, running at 3 GHz internally and 1,333 MHz externally – a new clock rate that will be officially introduced tomorrow morning. Since our engineering sample had its clock multiplier unlocked, we were able to increase its clock multiplier from 9x to 10x, simulating a future quad-core CPU running at 3.33 GHz – a “Core 2 Extreme QX 6950”. We compared this new CPU to several other CPUs from Intel, check it out.
