Hello, I have recently (yesterday) bought an XFX AMD radeon R9 270X graphics card which is written as " r9-270x-cdj4" model. I saw their official web site and realized that XFX provides so many R9 270x models like cdfc, cdj4, cdjc etc. My question is.....are these models different from each other????? Game-Debate said that XFX R9 270X has merely 185.5 GBPS bandwidth........will this...so called cdj4 edition of R9 270x provide me the best performance??? (also written that it was made in china!?)
 
Solution
This is a typical R9 270X card and should give performance similar to the reference R9 270X benchmarks.
The only models that are substantially different are EDJR, EDJ4 and EDFC as these have 4 GB of VRAM where your card has the typical 2GB of VRAM.
As the R9 270 X is a mid-range card, 2 GB of VRAM should be fine.

also I didn't get 6-pin to molex 4-pin cables and crossfire bridge......the CD says amd but when I start the CD..it says ati radeon..is it older VincentP ????
 


AMD bought ATI a number of years ago and at some point re-badged all their new cards as AMD. Any distinction between ATI and AMD isn't important.
You shouldn't need the power adapter. It is much better if your power supply has these PCI-E power connectors rather than using a molex adapter.
