Gigabyte HD4850 GV-R485-512H-B Review

» Discuss this article (3)


The Gigabyte HD 4850 is just your average Radeon HD 4850 with the exception of its overclocking headroom. The card performed almost exactly the same as the competing 4850. When I overclocked the card, I wasn't expecting it to go far since the temperatures were quite high as it was (the card was idle at 70 degrees Celsius!), but this Gigabyte 4850 still pumped out some pretty good clock speeds. I was able to raise the core GPU clock of 625MHz up to 675MHz and the memory from 990MHz to 1075MHz, but I couldn't go any further due to temperatures because they were approaching almost 90 degrees Celsius! With an aftermarket heatsink and fan, I have no doubt in my mind that this card can be pushed even more because it's hard to overclock with a video card that idles at 70C without any aftermarket parts. However, a 50MHz increase on the GPU clock speed is good headroom if you ask me. If you look back at our first 4850 review, you'll notice that this Gigabyte HD 4850 was overclocked twice as much as that card. Also, I was pleased to see how slim this card is because a lot of cards that have been released lately have taken up multiple PCI slots for cooling purposes. If you're looking for a video card that performs well in today's hottest games but doesn't break the bank, the Gigabyte HD 4850 is the graphics card for you. It supports DirectX 10.1, Shader Model 4.1, HDMI, CrossfireX, has onboard HDCP, and runs on a fast 55nm chip, all while leaving a good amount of overclocking headroom.
