Onboard video uses system memory. So the bandwidth to memory is limited by |
| 10 |
PCIe, HT, and two hops to the memory and back. Figure memory bandwidth around |
| 11 |
800 MB/s to 1 GB/s tops, if nothing else is going on on the bus. |

Even an inexpensive 6200 with onboard memory has 4 GB/s or more. If you need |
| 14 |
the performance, get either a 6600 or wait a bit for the newer 7600. |
