Intel's newest 1333 MHz front-side bus processors take the center stage
Intel today announced a new lineup of
1333 MHz front-side bus
dual and quad-core processors. The new Intel
1333 MHz front-side bus
lineup consists of three dual-core and one quad-core processors. The dual-core lineup features the new Core 2 Duo E6550, E6750 and E6850.
Intel clocks the lowest Core 2 Duo E6550 at 2.33 GHz, which slots between the previous 2.13 GHz E6400 and 2.4 GHz E6600. Intel does not have a 1333 MHz front-side bus Core 2 Duo E64xx or E66xx planned. Intel intros the Core 2 Duo E6550 at $163, below the current retail prices of the Core 2 Duo E6400.
Intel Core 2 Duo E6x50
The middle of the 1333 MHz front-side bus consists of the
Core 2 Duo E6750
. Intel prices the Core 2 Duo E6750 at $183, $20 more than the E6550. The extra $20 yields a 330 MHz higher clock speed. Intel’s Core 2 Duo E6850 fills the top of the dual-core lineup. The Core 2 Duo E6850 raises the clock speed another 330 MHz to 3.0 GHz. The increased clock speed comes at an extra $83.
Intel’s Core 2 Extreme receives a 1333 MHz front-side bus makeover as well. The new
Core 2 Extreme QX6850
is the only quad-core processor to transition to a 1333 MHz front-side bus. Intel clocks the Core 2 Extreme QX6850 at 3 GHz, a slight increase over the QX6800’s 2.93 GHz clock speed. The Core 2 Extreme QX6850 has a $999 price tag.
Also launching today is a new Core 2 Quad processor, albeit with a 1066 MHz front-side bus. The new Core 2 Quad Q6700 clocks in at 2.66 GHz, similar to the previous Core 2 Extreme QX6700. Intel debuts the Core 2 Quad Q6700 at $530.
Despite the new product introductions, there are no price cuts on existing products today. Nevertheless, Intel
plans to cut prices
on most dual and quad-core products next week. When the new price cuts go into effect, the entry-level Core 2 Quad Q6600 drops down to $266, matching the Core 2 Duo E6850 in price.
Expect the new Core 2 1333 MHz front-side bus processors to pop up in retailers immediately.

RE: Worth getting the Q6600?

Aftermarket coolers are not bad, and I recommend them. Newegg has a Scythe Ninja for 39.99...which is a good cooler. Many sites also have reported that the current chipset bottleneck on the DS-3 and DQ-6 is 400mhz (1600mhz) bus. Anything over and you have worse performance or little steps in performance.
What you should remember is that raw speed isnt everything. The best bet to try is to drop the multiplier from 9 to 6 and then run the quad core at a front side bus of 400mhz. You would actually be able to do this on a lower voltage.
(currently I run at 1.068v at 400 x 6 on the E6300)
What happens is that you actually....drop in required clocks from 9 to 6 (1/3rd) meaning that the processors will access more frequently. Due to the way the quad cores are set up, to see any real performance, that front side bus has to be stepped up from 266 to 333 - 400 because we are talking about splitting your bus into 4 cores instead of 2.
If you want more speed.....then increase the multiplier, making sure your aftermarket cooler effectively can dissipate the heat. You should be able to run at 3.2ghz and 3.6ghz, I would not recommend busses higher than 400mhz unless you buy a new motherboard with the upcoming chipsets which have a higher bottleneck (between 520 and 600) than our gigabyte motherboards.
