Gainward HD4850 Golden Sample. 700mhz vs 625mhz. More then a 10% increase. That's right up there with the fastest clocked GTX280's, in terms of an overclocking increase.
I don't have numbers for lowerend cards, but I'm sure they can do the same. The HD4870 is more of an exception, and is probably very close to it's limit allready (yet stable).
Also, since XFX announced it 3 weeks ago, and are offering cards right now, they probably didn't have time to get out oc-ed cards. Because if I recall correctly, it always takes a little while for oc-ed cards to enter the market.
I'm not backing up solofly with his comment regarding Keys, but this forum is going down the drain. And it's pretty sad to say the least.
Right, so a 4850 should have enough overhead to reach 4870 speeds with enough voltage and cooling, which isn't unexpected as that's what a 4870 is, an overclocked 4850 with GDDR5. But that doesn't leave much overclocking headroom for the 4870 does it? Again, you're pointing out a single example to the contrary and calling bullshit for a lack of overclocked parts for the last 2-3 years? At least a few others came up with a plausible explanation with backup with regards to ATI's policy on vendor overclocked parts.
As for your speculation with regards to XFX, EVGA, BFG, etc. they do typically have their entire OC line available at launch, with often 1 or more OC'd variants offered in addition to a stock model. Also SSChevy2001's link above seems to indicate XFX is offering a XXX offering at launch.....with 25MHz overclocks for both the 4850 and 4870.
And as for these forums going down the drain? Have you really been here long enough to know? Nothing seems to have changed from as long as I can remember. A vocal, overwhelming majority of ATI/AMD/underdog supporters crying about a vocal minority of Nvidia/Intel/favorite supporters. Heh.
