PCIe 2.0 x16 Total bandwidth 8Gb's
Radeon HD3870 - Transfer rate 2.2Gb's
Radeon HD4870 - Transfer rate 3.6Gb's
Radeon HD4870X2 - Transfer rate 7.2 Gb's
Radeon HD5870X2 - Transfer Rate X.X Gb's
I think its safe to assume the the 5000 line will offer more performance then the 4000 line which in turn will bring an increase in transfer rate on the PCie 2.0 bus (look at the jump between the 3870 and 4870). Given that a Radeon 4870X2 is nearing the maximum of the currant standard I worry for the Radeon HD5870X2 will be badly bottlenecked.
Please tell me there is a flaw in my logic here or that I'm missing something. Sorry if you think this is FUD but I just to get this of my chest. Thoughts?
