Today a test and review on the new AMD ATI Radeon HD 4870 1024MB. Obviously ATI is releasing a 1GB model to compete with the new Core 216 version of that GeForce GTX 260. The 4870 series really diggs that GDDR5 memory bandwidth and what’s the cheapest thing to do to gain some extra performance Increase the framebuffer volume. Now that by itself is not going to work miracles yet in memory limited situations loads of high quality textures filtering and AA modes it will help you here and there. And a little bit of extra bite is all the product needs to get beat that Core 216 card again.
