AMD Radeon HD 6790 Review: More Mid-Range Might

[jijibu]

Nvidia has CUDA and PhysX... It's great Power. Nvidia has advantage in overclocking...

Only 3 HD 6970s being carried at NewEgg at this time.
One each by PowerColor, Sapphire and XFX.

Seems to be a weak response from the MFRGs.
... or maybe from NewEgg?

Is this test done with 16 or with 24 rops?

It was a GPU-Z bug.. sorry for the question

I own the 5770 and i think that moving from 128bit to 256bit didnt make any big difference as some 5770 reviews before though it might!

6790 need 2 x power pin and 6850 need only 1 power pin what a JOKE!! AMD FAIL!!

HD 6790 is a good card for its price as it competes with NVIDIA's GTX 460 768 Mb version. I still can't believe NVIDIA GTX 550 Ti is a bad card. Apart from beating the GTS 450, it can't beat the HD 5770 in some games.

I use two flat-screen VGA monitors with my PC and bought this card only to discover that its second DVI port does NOT support VGA, which was a major bummer and made me go back to the store and change the card with the 550Ti (the 460 wasn't available) on which both monitors work fine. All nvidia cards have DVI-I ports that support both DVI and VGA, why can't AMD follow their example, damn I would have had a better card now if they did...

Wow! I can't believe how messed up the whole crossfire thing is. First of all, you don't get a CrossfireX bridge with many cards. The card manual will tell you that it comes with your motherboard and your motherboard manual will say that it's "bundled with the graphics card". Then you've got the whole short vs. long issue. My mobo has the 2 PCIe2x16 slots 2 slots apart which provides a nice 1 slot space for cooling but likely also ensures that the standard Crossfire bridge which MIGHT be included with the graphics card will be utterly worthless.

On top of this, there is all kinds of outdated crossfire compatibility info out there and just when you think you've got it figured out, you find some new info which blows everything you thought to smithers. For example, you'd think that you could CrossFireX any 67XX card but NO! The 6770 & 6790 use altogether different cores and the official AMD compatibility chart shows them as NOT compatible.

Truth is, given that the more powerful card will get "crippled" down to match the lowest spec card, you'd be a fool to CrossFire anything other than exact match cards.

What else can I gripe about CrossFireX? Glad you asked! 90% of the damn etailers don't tell you what's in the freaking box. Why don't the card makers include a decent explanation of how to use CrossFireX in the product manual? Some cards have ZERO crossfire connectors and some have ONE and some have TWO. What the bleep is that all about?

Please Tom's Hardware, give us an article fully explaining the CrossFireX crap and how exactly to do it.

I have seen that you placed the 5770 quite a few times under the 550ti where the 550ti got lower frame rates on average and minimum. Besides that good article. The 6790 is a 5770 with 256 bit.

Too bad gtx460 has it's high price.

The charts are in order of price. The best cards are lower on the chart with higher frame rates.
