[NHW] RV740 ES using GDDR5 - Page 4

Arent jokes usually funny?
If you're referring to my "fake benchies", there was a guy flaming before I posted them but his posts got deleted, the "joke" probably lost half its value 'cause most people wouldn't know what happened before, it was related to the previous flaming...

Entry level will switch from DDR2 to normal DDR3 (yes the RAM kind, NOT the GDDR3 version). DDR3 chips are considered cheap now, and will be even cheaper as time goes.

DDR3 speeds range about 1.8Ghz-2Ghz for now. The 4670 1GB's using it.


However, the next midrange card (2009 Winter) should be 128-bit. GDDR5 has already reached 7Ghz in super chips, the more practical ones would range at 5Ghz or so. That amount of bandwidth is enough for a great midrange chip (40% faster than 9600GT possible) so no worries there.


RV870 will use 256-bit, though. I don't think GDDR3 will even be in the picture.
How much die space can they save from 256bit to 128bit?

They wouldn't just save die space, they would save a lot of room around the memory chips as well since they would need about half the connections to the PCB.

Are the changes to GDDR5 would make it require PCIE Connector?
What thing actually causes it require to PCIE connector?

GDDR5 uses more because of total clockspeed. (It uses less per clock though)


That pushed power consumption near/above 75W so they need it. But the chip should be rather cool otherwise.

That's dependent on the amount of amperage that the card needs to function. That is more a matter of what the GPU requires, the memory requires relatively little power in comparison.

So with this shrinkage, are we only going to see 5 bucks off the next gen cards? Or are we actually going to see a 150 dollar card get dropped to 100?

Currently everything gets cluster****ed into the $120-90 region, which is cutthroat.

I'm not sure if there's even going to be a "new" product model/SKU. It might just silently kick the 4830 off and become the new version.

MSRP might not drop/drop a little (120 to 100, 9600GT is redundant), but you bet that the lower production costs will prompt partners to cut as much as possible (given that the 8800 and 9600 are hot cards in their segments)
