Nvidia misses GTX470/480 launch targets

[tajoh111]

grey screen ati issue is mostly due to clock/voltage profiles I think.

i dont see 480's being percentage overclockable equal to 5870's? But honestly I havent watched too closely just yet, my 4870x2 is keeping me happy lately.

@ snake..u call that OC? a stock xfx oc of 25mhz? knowing these cards can do 1000+....

1000+ mhz 5870 are rare. The toxic version of the vords have slightly higher volts and much much better cooling and they only reach 972 and 975 mhz, which is only a 47 and 50 mhz overclock respectively. The final frequency of these cards should be considered above average considering the cooling and additional voltage.

Most reviews for gtx 480 were hitting 800 mhz, which is a 14% overclock.

Heres among the best overclocks which they achieved a 825mhz or 125mhz OC

To among the worst they they achieve a 775mhz or 75mhz OC

This leads to a range between 10.7% overclock to 17.9% overclock. If we apply this to standard 5870 core speed we got get an overclocking range of 940mhz to 1002mhz. This is well within the range for the type of overclocks you will see with a 5870. You might be able to get more with additional voltage, but that hardly considered a fair overclock comparison. Especially when these cards have expensive cooling, more expensive PCB and higher voltage.

Heres an example that falls well below that range.

890mhz which is only a 5% OC. I don't even think this is the worst as I remember a 872mhz or 22mhz OC.
