Tom's Hardware: ATI Radeon HD 4770 In CrossFire: Unbeatable At $220

[Manicdan]

the 4870: 800 stream processors, 256 bit GDDR5 and 512MB (i think i have the specs right)
chip #1 has 1600 SPs, 512 bit of 1GB (this would be the duel chip combined)
chip #2 has 2x 800 SPs, 2x 256 bit of 1GB each (this would be the X2)

technical specs look the same with the exception of the difference in ram size. but in theory id think the first one would perform better since the 2 chips would talk to each other at much better speeds and lower latency (i guess) and would probably be more versatile since it wouldnt have to worry about xfire scalability, it would just be 100% more powerful in any situation, instead of up to 90% in alot.

Makes sense to me, but like the guys above, I talked about MCM and adding another 256bit memory and got flamed and laughed at.

I wouldn't take it too seriously bro. People get flamed and laughed at for many reasons here at XS. There are a lot of 13 years old 1337 haxors lurking here thinking they know everthing and the only way to show this is by ridiculing the others.

Yeah I know, I just feel sorry for the threads their lurking in

Another thing I don't get. How can some folks complain about 8 X 8 for Crossfire while we know X2 versions of the cards rock. An X2 Card would have the same effective bandwidth as PCI-E 8 X 8 on many Intel chipsets, right?

True... 8x isn't really a problem yet regardless of what some people claim.

That's what I thought, thanks!
