The LGA-1156 Socket: Size and Installation

The first Core i7, Bloomfield, went into a 1366-pin LGA socket:

A year later we have Lynnfield, and it fits in a much tighter space:

The LGA-1156 socket and Lynnfield CPUs are about as big as the old LGA-775 sockets/chips:


From Left to Right: Intel Core i7 "Bloomfield" (LGA-1366), Intel Core i7 "Lynnfield" (LGA-1156), Intel Core 2 Quad "Yorkfield" (LGA-775)


Note the pad densitiy of Lynnfield vs. LGA-775 processors

The installation process is largely the same as any other Intel LGA socket, the difference being that LGA-1156 uses a new one-sided retention mechanism.

After the socket is "open", gently place the CPU on top of the pins. The chip can only fit in one direction so just pay attention:

With the chip in the socket and the lever still pulled back, move the socket cover over the CPU and slide its teeth under the retention screw on the opposite side:

Then, lower the lever, lock it in place and you're good to go:

    Clock to clock comparison with turbo off..

    Phenom II 965 comes in last place, due to IPC differences which is why AMD had to release higher clocked (should I say "overclocked") Phenom II to compete against Core 2 and Core i5/i7 series.

    Why compare to a Phenom OCd by 600mhz? The Phenom doesn't do it automatically like the i7

    It's biased because Intel is giving you more features?? The whole point of comparison is to determine which is better. Next you'll say it's biased because it's comparing a Nehalem to a Phenom II.

    I'm posting this to an older review, but just wanted to make a comment. I noticed all the reviews that have the Q9650 included, compare it to the Phenom 965... which isn't a fair comparison at all, because the Phenom 965 is running at a considerably faster mhz than the Q9650 is. Plus the Q9650 can overclock much faster with no voltage increase. I would bet the Q9650 is faster than the Phenom 965 at the same clock speeds.
