Conclusion: However as this was the first 40nm GPU ever, we were still keen to test it out. When you look at it on paper the Radeon HD 4770 is evenly matched with the Radeon HD 4830 , at least for the most part. The core configurations are very similar, the memory bandwidth is about the same with the advantage going to the Radeon HD 4830 here. The Radeon HD 4770 core is clocked significantly higher but it comes back to the 128-bit memory bus.
Excerpt: Thanks to its GDDR5 memory and a new 40nm manufacturing process, the ATI Radeon HD 4770 sets a new bar for graphics-card performance at around $100, while using less power than beefier boards like the Radeon 4850.
Pros: Excellent performance at the $100 price point, Uses less power than comparable cards
Cons: Requires PCI Express power connector, Takes up two expansion slots, Loud cooling fan
Summary: Although we have had less than one day to play with the Radeon HD 4770, giving us a very limited time in which to benchmark this exciting new graphics card, a few things are already very apparent. First and foremost at $100 US the Radeon HD 4770 is an absolute steal, there is no question about it.
Summary: AMD really has opened up a range of new opportunities for budget users with their latest processors and graphics cards. The Phenom II X4 940 is amazing value at just $190 US, and it is a great way for users to get their hands on a quad-core processor, while its bigger brother the 955 is currently priced at $245 US also making it very tempting.
Conclusion: Although the HIS Radeon HD4770 has been around for quite a while now, it still boasts performance which many modest gamers will be more than happy with. For any gamers or enthusiasts looking to spend under £100 on a graphics card I fully recommend you give the HIS 4770 a try. It offers performance which is on par with the 4850, although dropping slightly behind in the Anti-Aliasing department and comes in at £20 less. A saving I’m sure many will be happy with.
