new batch of 5800 series lower quality because of 5900s?

I think I read somewhere that they were using up the good 5870s for 5970s and that the retail 5870s now, or soon, will be lower quality?

Doesn't make sense to me why AMD would do that since the 5970 is clocked lower than the 5870.
 
They are bin sorting chips. Like they always bin sorting chips. The chips that achieve the default clock speeds at a lower voltage will be delegated to the 5970s to keep the tdp down for the 5970. This is no different than ATI making 4850s and 4870s it is the same die but based on performance they will use that chip with a different pcb with a different purpose in mind.
 
They very well might be binning the 5870's that overclock more in preparation for a 5890 later too.

So we're thinking the 5850 is the best sub $300 card for the next 3 months?

I would buy the 5850 over the 5870 now that the 5970 is available.

The 5850 and 5870 is only separated buy a few frames. I rather CF 5850 or just get one 5970, it's more cost effective.
 
People have already been complaining about 5970s downclocking. Since a 5970 is down clocked to a 5850...not sure if they even have to bin the chips.

Where did you hear this rumor?

Because it pretty much confirms that 5890 is going to be nothing more then a ultra binned rv870.
 
I think what the OP means is that AMD are cherry picking the 40nm cores so the ones with bigger overclocking potential go to the 5970 cards.

This does not effect the stock quality of the 5870s, all the cores are tested to work before the cards ship, all it effects is the potential overclocking headroom of the 5870s.

The reason the 5970 has cherrypicked cores is because the card is marketed as an overclockers card, the card comes with cooling which is designed to handle way more thermal output than what the card produces at stock, it also has high quality voltage regulators and comes with overvolt tools to allow you to overvolt the card and increase overclocking headroom.

The 5970 is basically 5870 hardware downclockde to 5850 speeds, the reason they did this was to keep inside the 300W limit as defined in the PCI-e2.0 specifications. Most 5970s have no issue reaching the same kind of overclocking speeds the 5870s reach, 1Ghz+ on the core, 5100-5200 on the memory.

Well said mate, question answered.
 
Uhm, hasn't this pretty much been standard operating procedure for both teams for many many many many many many years?
 
do you guys seriously think that AMD just started doing this now? 5970 was released a month ago, and was in production for a while before that, most likely the 5870 chips have always been binned to give the lower voltage chips to the 5970s, not just after the 5970 launches, since it takes time to produce these cards.

No vapor chamber/heat sink contact on the second set of vrm limit OC potential on the 5970. Although I see people getting their core clocks up pretty high with these cards.
 
Considering the 5970 is actually clocked lower than the 5870, it makes no sense.
