Ok drum roll please. I think we have a new champion over the q6600. Granted the q6600 is $100.00 less than a Q9450 so its not really apples to apples.
Here are my findings with the q9450.
1. I ran it at stock 2.66ghz and it came in at 585 in 18:30 sec right behind the q9300 at stock. This is puzzling since the 9300 stock is 2.5ghz. Anyway this proves that these new 45nm quads are about 400mhz faster on each core than the older 65nm chips. At least thats what it seems when you look at what the kkm's result with the 9300 and mine with the q9450.
2. I started overclocking and it looks like I will probably land around 3.4ghz-3.6ghz without breaking a sweat. Its the x8multi and fsb wall that stops it there pretty much. Im stress testing it right now at 3.4ghz and my temps max out at 55c on an air cooling which is nowhere near the danger zone of 70c. I also have 8gb of ram which is making the overclock a little harder than if I just had 4gb. I may have to drop down to 4gb or ram if I want to reach 3.6. I am having to crank the voltage up everywhere to get the 8gb stable on my abit 1p35-Pro motherboard.
3. So if I can get 3.6ghz which it looks like could happen thats like a q6600 overclocked to 4.0ghz. That should put my benchmark right at the bottom of the octo-cores which is pretty amazing for a single quad core chip.
Let me just say also, that as of about a month ago the only thing I had done inside a computer is put in ram and a video card here or there. So with lots of reading and resarch you can save yourself a lot of cash by building your own system and overclocking it. I spent $1,000 for all the components and I am pretty excited how it is turning out. Im keeping my fingers crossed that it will pass the stress test at 3.4ghz right now.
In 3 months we have new champion quad core at budged build price
