Gigabyte GV-R477D5-512H-B Radeon HD 4770 Videocard Review

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.
