Overclocked vs stock @ 3.7GHz

Forum Overclocking : CPUs Overclocked vs stock @ 3.7GHz

example:
955BE stock 3.2GHz and then clocked it to 3.7GHz.
then get a 980BE and run @ stock 3.7GHz..

are they equal or does the 980BE have the advantaged because it running stock with less heat and possible less voltage.?
are they also executing the same amount data.?

I have so many questions about this....
on paper they should be equal if both Denebs with C3 stepping @ 3.7GHz.
but are they really.?

Same TDP - Same Stepping - Same Clock Speed - Same Arch - Same Memory Controller - Same EVERYTHING.

They would run at an identical speed. Its like comparing an old E8400 to an E8500 - Up/drop the clock speed (respectivley) and they are the same chip

yup, deadjon hit it on the head. the only reasons for different chips under the same family is to cover more market area price points. i dont even want to get into binning and such.

so the heat doesn't detriment the performance as in the amount of data executed or anything you think.?

Same cpu but the 980 is binned higher, meaning it needs less voltage to run at 3.7ghz than the 955 does. The 980 will be 125 watts at 3.7ghz and the 955 over that maybe something like 140 watts. The 955 might top out oc at something like 3.8ghz and the 980 at 4.0ghz.

well 980BE's can hit 4.2GHz on stock cooler so it's definitely higher than a ceiling of 4GHz..

On paper both will perform the same, in real life, the 980BE will perform a little better.

What about the 970? It's clocked at 3.5ghz, and is $20 cheaper.
I doubt the max oc speed would be more than about 100mhz between the 970 and 980. The 970 is binned 300mhz higher than the 955 so that is a good starting point.

it's not about pricing.
it's about if an overclocked chip performs the same, better or worse then it's clocked equivalent running @ stock.
does the heat, voltage, does the higher binning and whatever else have an effect and therefore doesn't execute the same amount of data but @ same clock speed.??
the 955 vs 980 was the example.

heck, look at my sig....
do I need to upgrade to a 970 or 980BE.?
I'd say NO..

I thought maybe you were upgrading a system for someone.

If say both cpus were clocked to 3.7ghz without using the fsb to overclock. They are the same exact cpu just one is binned lower and has a lower stock multiplier.

At the same speed, both should benchmark exactly the same. The score should be within the benchmark's margin of error.

when I had my PHII x 4 925 running at 3.5ghz and ran all the benches
3Dmark,Passmark,Sinebench etc
it scored the same in benches as the 970BE stock
the tradeoff is the extra wattage and heat
but since your 965 has unlocked multi and doesnt need alot of voltage
so upgradind to a 970 or 980 doesnt seem to make sense
you might gain 200mhz-300mhz or so
and really what is that
usually takes about 500mhz speed increase to really notice a difference

"a difference you cant notice isnt truly a difference at all"-somebody wiser than me said that

I know you dont like the Thubans
but your best upgrade path (not counting FX)
would be a 1100T BE
you could have six cores easily in the 4ghz range

just my opinion
I could easily be wrong....
