If you missed the launch of ATI’s Radeon HD 4770 GPU you’re in for a special treat today. PCSTATS is testing out Gigabyte’s GV-R477D5-512H-B Radeon HD 4770 videocard alone, and in Crossfire mode so you’ll know exactly what two of these mainstream cards can do for you! We already know one Radeon HD 4770 graphics card offers great performance for under a hundred bucks, the real question is what level of gaming performance will two 4770’s teamed up under Crossfire deliver? Mainstream videocards often scale faster and farther than pricey flagship videocards, so it’ll be interesting to see where two Radeon HD 4770’s stand against videocards several times their price.
First the basics. ATI’s Radeon HD 4770 (code name RV740) is derived from the venerable Radeon RV770 GPU. The Gigabyte GV-R477D5-512H-B videocard has its GPU clocked at 750MHz and is equipped with 512MB GDDR5 memory running at 800MHz, giving it a bandwidth of 51.2 GB/s. The memory bus is 128-bit wide, which should make for an interesting comparison between it and the mainstream Radeon HD 4850. PCSTATS will breakdown all the numbers in a moment, including benchmarks with the GV-R477D5 card running in Crossfire, but first let’s introduce you to Gigabyte’s GV-R477D5-512H-B PCI Express 2.0 x16 graphics card.

The frequency of graphics card releases now compared to two years ago is just jaw dropping. There used to be three models; a low, mid and high-end model. And while we still have that base structure today, there are so many models that fit into each category. These days we have high mid range cards and low high end cards amongst the main three categories; the reason for this is because of the amount of power these cards offer.
The latest card to hit the market is the HD 4770 which expands upon the HD 4700 series from ATI. The weird thing is that it’s a series that we haven’t heard about a whole lot leading up to its release, especially in the new model market. What we’ve seen from ATI lately are models in the HD 4800 series, HD 4890, HD 4870, HD 4850 and more.
With the GIGABYTE HD 4770 in hand we’ll find out if the model is jut ATI getting some attention or a model that’s actually worth checking out in today’s market. Let’s have a look at what GIGABYTE has done with the package and bundle before having a closer look at the card. From there we’ll find out just how it performs.
