ATI Radeon HD 4000 Series discussion

[informal]

That is pretty much what I am begining to expect, RV770Pro = 480SP. RV770XT = 800SP

I am hoping that the HD4870 leans more towards 9800GX2 performance than 9800GTX as I am looking to upgrade from a 8800GTS

pop two of those in and then you will be faster than G280GTX (if software supports Crossfire).

If the HD480X2 is going to be any good it better have 2GB of RAM or a vast new improved multiGPU technology otherwise it is going to be the same old problems which can effect the GX2 and HD3870X2's due to 512MB of RAM percore?

You are very wrong.There is only one RV770 chip,and it has 800 Stream Processors or 160 shader processors with 5 stream pr. in them.
There is no 480 Sream proc. RV770 chip ,there never was.
To check this,you should look at Firestream 9250 thread in which AMD claims 1TF for basically Radeon 4850 with 1GB of frame buffer memory!One teraflop = 625Mhz x 2Flops x 800
