Well the ST one for starters.
ST has an ARM with a GPU (Graphics Processing Unit)?
Note that the ARM11 used in RPi is quite a different beast than the Cortex M0/M3/M4 parts that are usually aimed at microcontroller replacement. ARM11s are aimed at unix-running (and similar OSes) "appliances" like cell phones, cable TV boxes, Digital Video Recorders/players. and stuff like that. ARM11 is a little obsolete (the Cortex A8, as used in beagleBoard, is its nominal replacement, I think.) But that also means that it's "mature" and companies like Broadcom have those lovely System-On-a-Chip (SOC) chips with all sorts of large-system peripherals (GPU, MMU, DRAM controller, USB host, etc.)
