A method of prefetching attribute data from storage for a graphics processing pipeline comprising a cache, and at least one buffer to which data is prefetched from the storage and from which data is made available for storing in the cache. The method comprises retrieving first attribute data from the storage, the first attribute data representative of a first attribute of a first vertex of a plurality of vertices of at least one graphics primitive, identifying the first vertex, and, in response to the identifying, performing a prefetch process. The prefetch process comprises prefetching second attribute data from the storage, the second attribute data representative of a second attribute of the first vertex, the second attribute being different from the first attribute, and storing the second attribute data in a buffer of the at least one buffer.
