[SOLVED] Qx6800 vs q6700

[mitchell.wong]

Hey guys which do you think is better? I tried researching but can't get a straight answer

basically the only difference is clock speed. the qx6800 runs at 2.93 ghz and the q6700 runs at 2.66 ghz.

the qx6800 uses 130w vs 105w for the q6700. basically to push the higher speed. instruction set, architecture and so on are identical.

so if you're not gonna oc the chip, the qx6800 gives you a bit more speed.

So the qx6800 will beat the q6700 ever so slightly right? Other than clock speeds it's the same chip and everything?

 

[Math Geek]

correct, very little increase at less than 300 mhz but it is faster.

all the specs, architecture, instruction sets and so on are the same so they are based on the same design with different clock speeds. power hungry little chips though so be sure you got cooling for a 130w cpu!!

Biggest difference is in application. Because if power restrictions the q6600/6700 could be used on some older 775 chipsets still running ddr2 if bios allowed, but other quads run requirements too high for those older chipsets. Other than that, with today's technology and software, there's really no difference between the two, clock speeds not withstanding.

I have a d975xbx2 motherboard and have a q6600 so I think the qx6800 will be good enough. My power supply I know for a fact is at least 550w psu. Is this a good upgrade for retro tech?

here is an old review for the board using a qx6800

https://bit-tech.net/reviews/tech/Intel_D975XBX2/4/

so i guess that shows it can handle the chip if you wanna go there. but moving from a q6600 to a q6700 is not worth the trouble so i guess it would be the qx6800 or nothing.you'll see a small bit of increase but such an old cpu won't make much difference.

i have a q6600 system i still use and i did the tape mod to it to get it to 3 ghz which is roughly the same as the qx6800. i barely noticed any difference at all. but i feel better knowing it is running at 3 ghz 😀

perhaps you can look into that first before dropping cash into the new cpu. a quick google search for "q6600 tape mod" will yield plenty of how to's and forum conversations about it. took me longer to reaply the thermal paste and reset cooler after doing it than it did to actually apply the little strip of tape.
