The base frequencies of the Raven Bridge APUs have been boosted over their predecessors (R3 1200/ R5 1400) mostly to offset the drop in L3 cache (in the case of the 1400) as it featured 2x CCX, and thus had double the L3 Cache. Though, fortunately this also means that the process has been improved and that a 4GHz overclock is a fairly easy achievement using 1.38V. The 2400G was a little more temperamental, requiring the use of high/extreme Load Line Calibration. The previous ceiling is still in place in regards to maximum OC results, making 4.1GHz fairly difficult.
The Vegas 8/11 GPUs too can be overclocked, and have their performance improved, their base clocks of 1100/1250 can easily be clocked to 1500MHz, and with 1600MHz possible. At 1600MHz we experienced some artefacts on the Vegas 8 so reduced it back down to 1500MHz. The GPU performance can also be improved with faster memory, however we are limited to around 3200MHz in these tests due to our memory modules, which is only a little over the 2933MHz native support. Here we would like to note, that, with the motherboard we tested, we were only able to allocate up to 2GB memory for use with the integrated graphics, which is a slight shame as this may cause a bottle neck on many modern games (even the no-so demanding ones) at 1080p.
Temperatures
To get the temperatures, we fully loaded the CPU and iGPU using the AIDA64 stability testing tool. At stock frequencies, the temperatures are significantly higher than what we would expect from the CPU alone, and we would expect the temperatures to be significantly higher if you are using the provided stealth coolers. Once overclocked, the APUs temperature sits firmly alongside that of octo-core CPUS, however with adequate cooling, these temperatures are nothing too concerning.
