Theres not much info about this card but aren't these crippled 4890s(RV790, not RV740)?
Which would also mean its on a 55nm process.

GPU is RV790.

Essentially an underclocked and partially crippled HD 4870 , cheers .
The real world performance shouldn't too shabby , though .

Seems pretty adequate for the price, 11.2k mega pixels a second is plenty for any moderate gamer, running on a 40 nanometer gpu it uses less power then the 4870 but has pretty much the same performance in games aside from the 800 mega pixels a second more the 4870 has, but who wouldnt mind to pay $30 less for a card with near the same performance. also, the 40nm gpu will generate less heat therefore giving you a higher overclock to easily surpass the 4870. in my opinion the only thing its missing is DirectX 11.

The specs are wrong. The 4860 has a 256-bit bus, not 128-bit

@ McArthur

That's because the GPU is RV790 and not RV740.

I'm pretty new to video cards and could use some educated opinions on a question I have. I understand that the higher the number the better the card (essentially). I understand that clock speed and memory size/type hold a lot of weight in video cards, but how much weight does memory interface carry? I ask b/c this card (HD 4860) has a 256-bit interface but a higher rated card such as the (HD 5770) only has a 156-bit interface. How do these two cards compare?

Well I guess this isn't the website to get answers from. Thanks anyway..
