There are some clear benefits to the additional 512MB of graphics memory present on Gigabyte's Radeon HD 4850 1GB graphics card in some titles, but they're not there in others. Over time, the industry trend is definitely moving towards more graphics memory - that trend has existed for years now and it's not going to change any time soon - but the improvements on the Radeon HD 4850 1GB aren't quite as profound as they are on the Radeon HD 4870 1GB.

That is something to do with the resolutions that the Radeon HD 4850, in general, delivers an optimal gaming experience - they're not as high as they are with the Radeon HD 4870 and so the gains aren't quite as obvious. Without a doubt, they are still there though and the decision to opt for a 1GB Radeon HD 4850 over a much cheaper 512MB variant.
