Gigabyte Ready with 1 GB Radeon HD 4770 Variant
Gigabyte has a custom-design version of the ATI Radeon HD 4770 accelerator ready, packed with 1 GB of GDDR5 memory instead of the usual 512 MB. Already listed by several German online stores, Gigabyte GV-R477UD-1GI is selling for as low as 114.43 EUR. Although there are no pictures of the actual card, we can infer from the model name that it is going to have a custom design, featuring Gigabyte's Ultra Durable Video technology that makes use of durable components, and perhaps the signature Gigabyte-blue PCB.
Apart from the expanded memory, the rest of its specifications remain the same, including clock speeds of 750/800 MHz (core/memory). Notable specs of the Radeon HD 4770 include 640 stream processors, DirectX 10.1 support, and ATI CrossFireX support. A global launch of the accelerator can be expected soon.

cant find any benchmark on 16x/4x pcie 2.0 crossfire.
smart move Gigabyte - you may fool the general 'lets-buy-a-HP-Pc-from-pcworld' public but your not fooling me! good day to you sir!
Some people may choose 4770 1gb if price is right (would like to see how new 40nm 800 shader 128bit DX11 parts will be priced ) .I hope gigabyte did not put crappy loud cooler like this one on 9600gt

Whats crappy is the lack of speed control from Gigabyte's design. :shadedshu
1./ 1GB will significantly outperform 512MB at 1600x1200, 1920x1080, 1920x1200. A 1GB 3850 was 2-3x as fast as a 512MB 3850 at these resolutions (with FSAA dialled up), so I can only imagine the same holds true here. Remember, ATI hits a performance wall at 1600x1200 if there is only 512MB
2./ It will be the coolest, quietest, lowest power 1GB mid-performance card out there
3./ If running dual screens, the 1GB is a must for, e.g. FSX
I'm not slamming the 4770 as a card - im slamming the fact that they put 1Gb on it when they know full well, that its only going to amount to 1-2 or maybe 3 more fps if running with a single card.
I am also a firm believer that the 4850 is the same price range, so pay the extra $10 and get it instead, so we will see.
better two 4870 and cross fire here.
c'mon ATI, you couldn't do better with 40nm?
In fact, I remember reading the 4770 thread at silentpcreview forums where someone measured their power consumption under crossfire and it also doubled. (35+35)

Either this or the 4850 is on crack. Or you are actually wrong :nutkick:
Spec wise the 4770 is only behind on shader count and the higher clock speeds more than made up for it.
That fact scores pretty highly in my books. Count me in and interested in this card.
4770's are a beast of a card with a WILD overclock possible, two together (especially OC) will beat if not cream a 4890, and at settings a 4890 would game at, yeah we do want 1gb.
I have an example with a couple of cards of my own - GTX260+ 1792mb, take crysis, MAX it out, 1920x1200, enthusiast, with 16xQAA. one 896mb card cannot do this, period (worse than a slide show), runs out of memory. One of my 260's handles it poorly, but its obvious the memory does it's job, two is SLi render the game at 20-30 fps where 2x896mb cards would still be a slide show.
Odd example, but goes to show t'aint nothing wrong with more VRAM than less, especially if you like your high settings and might plan on a second card sooner or later.
To Wrap up, buying my cards was not money efficient whatsoever, I knew that, but these 4770 1gb's have a real market out there.
