Best Card for Folding Test Setup

How we tested

To obtain accurate comparisons between as many graphics cards as possible, it's essential that the Folding client is churning away on the same project between graphics cards. This can be quite tricky to achieve, as each project has a specific deadline and we're also unable to directly compare AMD and Nvidia GPUs, as well as graphics cards that can only use the GPU2 client such as the GeForce GTX 260 (rev2).

To get round the problem, we benchmarked a hoard of graphics cards in quick fashion to ensure as many as possible were benchmarked using identical projects. The vast majority of the Nvidia graphics card results are directly comparable with each other, as are those for AMD hardware.

There's a huge selection of graphics cards from which to choose, and many people opt to buy older examples second hand. Our tests show whether it's worth investing in new technology, or whether older hardware still offers good value in terms of Folding prowess, cost and power efficiency.

We used a monitoring program called HFM to monitor the progress of each graphics card and record its ppd (points per day). For the AMD cards we started with the HD 4870 1GB, which we tested using the GPU2 client. For the rest of the AMD cards, which included various models from the 5000 and 6000 series, we used the GPU3 client. On dual-GPU cards we also recorded a combined ppd from using two clients - one for each GPU.

For the Nvidia cards, we began with the GTX 260 (rev 2), again using the GPU2 client, and then tested a host of samples from the GeForce 400 and 500 series with the GPU3 client.
