Core 2 Extreme QX6850
Last but not least, we installed today’s crème-de-la-crème processor into our reference system: the Core 2 Extreme QX6850. Its internal layout is pretty easy to explain, as this product basically consists of two Core 2 Duo dies, each with 4 MB L2 cache and running at FSB1333 system speed. The quad core does provide noticeably higher performance in almost all parts of the SYSmark 2007 run. However, it takes almost equally long to complete the benchmark suite, which results in a higher total power consumption due to the fact that the quad core has a higher power requirement across all tests (94 vs. 77 watt system idle power). The situation may look different for computing-intensive benchmarks, where the four cores can outperform the Core 2 Duo by a significant margin. Our testing focused on SYSmark 2007, because it draws a good picture of typical PC usage.
