dear all

to people who struggle with their obsolete VGA card or Intel VGA chipsets, here's a new card from ATI thats powerful, cheap, low temperature and do not need monster power supply.. so anyone still using intel onboard vga , nvidia 6xxx or 7xxx or 8xxx or ATI 2xxx/3xxx , consider this card as your next upgrade.. you will see vast difference in performance and qualiti with this card..

a tip, use windows 7 and this card.. you will have better performance

as a reference, ATI 4770 is just a hair slower than ATI 4850 and it run cooler and require lower power.

AMD Radeon HD 4770
Cheap price, low power, and an enjoyable gameplay experience, all of this is possible in AMD’s new Radeon HD 4770 launching today. We will take the HD 4770 for a spin in six games and compare it to a NVIDIA GeForce GTS 250. You’ll be surprised at the level of gameplay possible for around $100 these days


Gameplay Experiences

Our gameplay experiences were interesting; most people were probably expecting the Radeon HD 4770 to blow the competition out of the water. It doesn’t do that exactly, but what it does do is provide a high level of gameplay enjoyment for an incredibly low price in a new low power envelope for its class. There were some very interesting performance results we experienced when using high levels of AA in some games.

Burnout Paradise played well on both video cards, and while the GTS 250 had a performance advantage, the actual gameplay experience was the same. Both video cards allowed us to play at 8X AA at 1920x1200, or 2X AA at 2560x1600. At $100 you can’t beat that. Crysis Warhead performed better on the GTS 250, and we were able to raise the in-game settings in comparison to the HD 4770. However, there were some areas in Warhead that didn’t drop in performance as much as the GTS 250 did. Also, when we increased the resolution the performance margin between the two video cards shrunk.

Fallout 3 also performed great, though the GTS 250 was playable at a higher resolution, but just barely. Interestingly when we set the game to use 8X AA though the performance between the two video cards reversed and the Radeon HD 4770 was faster! We also experienced this same behavior in Left 4 Dead. At 1920x1200 at 8X MSAA the Radeon HD 4770 was actually faster than the GeForce GTS 250!

FarCry 2 was again just slightly faster on the GTS 250, but not enough to make any difference in actual gameplay. Grand Theft Auto IV, like Crysis Warhead, did have an advantage on the GTS 250 and we were able to play at higher in-game settings. When we increased the resolution the performance margin narrowed however.


Fast AA

Here is what our gameplay evaluation has revealed; the Radeon HD 4770 is at its best when able to run with antialiasing enabled. Once we compared 8X AA between the Radeon HD 4770 and the GeForce GTS 250 we found the Radeon HD 4770 to be much more capable at that setting than the GeForce GTS 250. This really speaks to AMD’s AA efficiency since the Radeon HD 4770 has less memory bandwidth available than the GeForce GTS 250.

When running without AA the GeForce GTS 250 has a clear performance advantage. Interestingly, that performance advantage does narrow as the resolution increases.

We are excited just for the fact that we are talking about 8X AA and high resolutions on a video card that is around $100. To us as hardware enthusiasts, that is the most impressive part of this.


Another Enthusiast Card

The Radeon HD 4770 has a lot of potential for hardware enthusiasts, even at $100. We feel that AMD is finally making video cards for us hardware enthusiasts. We were excited about the Radeon HD 4890 from AMD. Our testing has shown that there is a lot of room for overclocking, taking it upwards of 1GHz. We feel this same way towards the Radeon HD 4770.

We think AMD has clocked this 40nm GPU relatively low for what it might be capable of. Both the Radeon HD 4890 and Radeon HD 4770 leave a very sweet taste in our mouths in terms of performance gains with overclocking. We can’t wait until third party apps support the HD 4770 so we can see how high she can really go. We will be evaluating an ASUS Radeon HD 4770 “TOP” that we have in the lineup, so we know add-in-board partners will have higher clocked 4770s.


The Bottom Line

The Radeon HD 4770 presents a very strong real-world value. At $99-$109 it provides a great gameplay experience compared to the competition. In most games the gameplay experience was the same. In only a couple was there any gameplay differences. We also feel that with some overclocking the performance of the Radeon HD 4770 might be able to make it near the competition in those games it currently lost to. The potential is there at least. The competition also has “OC” cards which may win back that performance potentially also. It sounds like competition to us, and that is good for the consumer.

The Radeon HD 4770 provides value because it performs as it does using less power and producing less heat with potentially cheaper prices. It is fact that AMD has introduced new technology in at this price segment, while the competition has simply re-branded old technology. AMD’s goals of making the Radeon HD 4000 series GPU scalable have definitely worked out well for them.

For all the above reasons mentioned, the Radeon HD 4770 has earned a HardOCP Editor’s Choice Silver Award.
