Ever since we saw the glowing review AMD's ATI Radeon RV740 prototype received, we've been looking forward to the day that the company would make one of these 40nm wonders available. It looks like that day might be close at hand -- according to these purloined slides, a little something called the ATI Radeon HD 4770 is due to make the scene next month in the $99 price point. This handsome lad sports GDDR5 memory, DirectX 10.1 support, a 750 MHz clock speed, a memory clock of 800 MHz using a 128-bit memory bus, a frame buffer size of 512 MB, and much, much more. Curious? Of course you are. Check the slides out below for all of the glorious details.

If it really costs $99.... If it really compares to 9800gt... Well, it might be the time to retire my 7800gt.
The Radeon 4830, which is a bit better than a 9800GT currently goes on Newegg for less than $100 already. And you can find the 4850's for around $130, and the 4870's for $170.
I'm in the process of building my next PC (a core i7 920-based system) but I'm having huge anxiety about purchasing a GPU. Video card tech moves so fast. I try to keep up on hardware, but I have a really hard time with graphics cards. It's making it really hard for me to pull the trigger and buy one. (I'm looking in the $250 price range.)
i say get a 4890 its pretty much the same as a 4870 but alot cooler then the rest of the high end cards and is a great performer, it will last you along time. AMD/ATI make great video cards. Just my Opinion
If you got money on i7, than something like gf275gtx might be safer bet. It's about $250 right now.
I personally am going to pick ATI for my next rig as better Linux compatibility is a prerequisite for me. And I'm not gaming that much anymore.
is there a real difference between 128 bit vs 256 bit?
What's the difference between a 2 lane highway and 4 lane highway? Now, if traffic was moving twice as fast on the 2 lane as compared to the 4 lane?
2 lane is 1/2 the bandwidth of the 4 lane, much as 128 bit bus is 1/2 that of 256 bit. But, the 128 bit in the 4770 is almost 2x as fast as the 256 bit bus on teh other cards... note the 3.2Gbps vs 2Gbps. So, even though the width is narrower, things are moving through it 2x faster... so the same amount of data passes through, theoretically and likely practically.
Just curious, how well can this run Crysis?
So wait... what would be better
4670 with 1GB of DDR3
or
4770 with 512MB of DDR5
4770

The 1GB on the 4670 would probably never even be fully utilized. Most benches with the 4870 512MB vs the 4870 1GB perform almost identical until you hit resolutions of 1920 x 1200+ (and even then its minimal), and the 4670 wouldn't even be able to run any modern games very well at that res.
its because of the 128-bit bus that the full 1GB can never be fully utilized
WTF engadget? I sent you the news tip and I don't even get a thanks?way to reward the people who help you make money.
Thanks :)
>128-bit memory bus
No.
Depending on how well it outperforms my 9600GT I may pick one up since it even has lower power requirements.
I have a x1950 Sapphire 512mb AGP card (I have a PCI-E slot as well)... will this 4770 perform better?
4670 >= 3850
4770 >> 3870
so offcourse 4770 will beat the x1950, also 4770 only use 80W of power, awesome
The specs look excellent for the price. Amazing performance really, for $99. :o
I have a fond place in my heart for ATI. Good cards, decent prices.
Would this run high-end games(COD:W@W, etc, I have a fairly new computer(this year) where the only lacking part is the video/graphics card) and being easy to self-install?
Last year I bought an ATI Sapphire HD 3870 which was the best card for the money ( ~90 EUR ) and I was very very pleased with it, for CAD and also for games.
So I am buying this, no doubt.
DO WANT!
I'd be upgrading from a NV 8600GT
Give me a ATI 4770 X2 with 150w and for 189$
or a ATI 4770 X3 with 210w for 269$, please.
Does it require a power connector or not?
nice fan design...looks badass even though looks really doesnt matter...
