AMD and Intel have announced that within the next months, there will be Four Core CPUs (Quad Core) in the market. We do have the first of many for a test in our labs now, from Intel! For your enjoyement, we run few tests with Intel's Quad Core QX6700 under MacOSX 10.4.8. Its not a secret that Core2Duo PC systems and run Mac OSX and without any major issues. Apple already have announced plans to use Intel's Quad Core series in order to deliver even faster performance at OSX, pleasing Apple funs. Everything runs x2, according to Apple for Core2Duo processors:

For all tests we used the following PC setup:

• Mac OSX 10.4.8 with all latest updates installed
• Intel XE6800 & QX6700
• Motherboard: Intel DX975XBX2 BIOS A2330
• Memory: 2x1GB Crucial PC2-8000 @ 800MHz CPU:RAM Ratio (CL4-4-4-8 2.1V )
• VGA: Asus X1600XT Silent
• HDD: WD 80GB SATA (primary)

Note that for all tests we used two processors. Intel XE6800 and Intel QX6700. Both processors come with unlocked multiplier, that means we can "emulate" the performance of the missing processors (aka E6600, E6700, QX6600 and QX6800).

MAC OSX 10.4.8 doesn't have any problem recognize the four cores of QX6700:
