It's not a question of need. Graphics are an embarrassingly parallel problem so any additional shader pipelines or processing units of any sort can be immediately utilized for additional performance.
It isn't like CPUs where half of the cores will languish until the user opens 20 more tabs in Google Chrome.

12 GPU cores on the Nexus tablet! How on earth they achieve that without making it overheat or ruining the battery life? Incredible!
Although, is there anything that runs on a tablet currently, that _needs_ that many gpu cores?
