Intel Core i5 650 ''Clarkdale'' Reaches 4.70 GHz on Air

jmke · 22nd October 2009, 10:37

The chaps reached a nice clock speed of 4.70 GHz (25 x 188 MHz) which is roughly double the original clock frequency. A core voltage of 1.424V was used. A point here to note however, is that the retail Core i5 650 will come with an upwards-locked bus frequency multiplier of 24 (24 x 133 MHz = 3.20 GHz). The processor at 4.70 GHz, was Prime95-stable for over 30 minutes. With an ambient temperature of 24 °C, the two cores heated up to 77 and 68 °C

A total of four models are expected; Core i5 650, 660 and 670, clocking in at 3.2, 3.33 and 3.46 GHz respectively. They will be priced at the $176, $196 and $284 respectively. All Clarkdale CPUs come with an IGP on die, and fit into the LGA1156 socket that currently powers Lynnfield CPUs. The branding is quite a mess - further complicated by Core i5 7xx series, which are quad core Lynnfields. One might have suggested a simpler Core i7 for Bloomfield, Core i5 for Lynnfield and Core i3 for Clarkdale, but Intel did not want to differentiate them this way.

Really?

yes really, promises a nice dual core OC CPU early next year, with HT!

I heard that the i5 was as good as i7 with tweaking but cannot find that url.
