Miscellaneous Benchmarks

Power Consumption While idling and when running wPrime and GRID 2

Notes

We have added the Intel Core i5-4670 into the mix, to see if the A10-7850K can handle the extra power available through Intel's four physical cores. Do note the 4670's graphics use the same architecture as the Core i3-4300's but are clocked in a touch higher - 1.2GHz vs. 1.15GHz.

AMD is soon to release a Dual Graphics and Mantel-approved driver. We will be taking a look at performance in those scenarios in separate articles.
