VTX3D HD7790 Review


We love a good low-end graphics card with some get-up-and-go here at OC3D. There is nothing better than spending peanuts and obtaining some great performance.

Recently we reviewed the GTX650Ti Boost, a graphics card which was not only at a great price, but had bags of performance on a budget. We liked nearly everything about it.

Returning to the fray with a card that sits between the pretty poor HD7770 and the excellent HD7850, AMD look to pick up the gauntlet that the GTX650Ti laid down with the HD7790. Is it going to be a great performer at a low price like the HD7850, or will it retain the low results we saw from its HD7770 brethren?

We hope for AMD's sake that it's going to be a stellar performer, because production of the HD7850 is being stopped to make room for this card in the Radeon range.

Technical Specifications

When compared to the GPU at the heart of the HD7850, the HD7790 has a huge reduction in the amount of transistors and shaders available. We've often commented that pure clockspeed looks impressive in advertising blurb, but the architecture is what counts when it comes to delivering performance.

Hot on the heels of the GTX650Ti, AMD have released their value GPU, the HD7790. We take a look at the VTX3D model.

Is AMD really removing the 7850 from their lineup?

I haven't heard or read that anywhere else.

all i can say is amd fails again, which is a massive massive shame

Agreed. Sadly we're approaching the point where failure is more of a regularity than success for AMD.

Its the 1GB 7850 thats being discontinued, and thats the one thats right on the same sort of money as the 7790. Fuzzy logic IMHO.

I don't like to be the one to complain but I'm finding it harder and harder to parse the graphs nice and easily. Is there a way we can get some sort of sorting going on?

08-04-2013, 08:25:22

I have a question with regard to the graphs as well. Are they running different versions of the drivers? Or are you benchmarking all of them again every time a new driver version comes out?

A quick answer is without redoing them every time manually.... No :/

Compared to the 650Ti boost this is shockingly bad. AMD seem to be focusing on undercutting NVIDIA on price across the board but at this price range, 20-40 more gets you such a big jump in performance (Gtx 660 starts at 150 on Aria) that you would be a bit daft to get one of these.

jesus f*cking christ that is a disgusting card.
really sad to see this card perform that bad, i though AMD would do better since they released the 7870 le. too bad they are removing that card as well.
650ti boost looks and performs better.

It would be pretty trivial to do using Javascript and RGraph but I don't know how the current system works and I assume you've already looked into it anyways.

Thanks for the answer nonetheless

for an extra 20-25 odds you can get a Gainward or Palit 2gb 660ti's from aria or spend a bit more again for an MSI variant albeit it not a twin frozr but still looks like it'll perform more than well enough.

You could also get a 2gb MSI 650ti boost with Twin Frozr cooler for not a lot more than a 7790 so i'm struggling to see what AMD were thinking of with this one.

08-04-2013, 09:48:14

i think what AMD is doing here is preying on the "not so knowledgeable" user that "thinks s/he is getting a top of the line card...mixing in the 7's and 9's....

may easily be confused with a 7970

08-04-2013, 11:08:32

If this card were single slot design, the lack of shroud may have gotten away.

08-04-2013, 11:47:47

Could be good little card for opencl apps like cs6 etc

*Blows a very loud raspberry*

Looking at the graphs I'd be surprised if this card could be classed as an upgrade from a 6870 considering your tomb raider scores weren't that far off of what I got on my old 6870.
And for 18 more you can pick up a 7850 it would seem this card has no real place for this card
