"Well, the real problem occurred when we tried to overclock the processor because its clock rate would drop to the default 3700 MHz or even lower, to 3500 MHz, at high loads even at the default settings. That’s a well-known problem, actually. AMD APUs aren’t very fast, so the manufacturer sets too high default clock rates for them to make up for the poor performance. The processor can’t work at that clock rate if the load is high. In other words, AMD’s processors are heavily overclocked even in their specified operating mode.
There’s no point in overclocking if the processor can’t keep its clock rate stable. Whatever clock rate you set, it is just going to be dropped at high loads."
This is not due to the APU ,but due to the motherboard/s and BIOS.
Most AMD mothebroards ,most of them on AM3+ ,some as we see here ,have the habbit to throttle.
On AM3+ you can simply tweak the CnQ ,APM or C6.The CnQ can work differently depending of the BIOS set-up (disabled by CPU or always enabled)
On AMD overclocking is done properly when you disable APM.
Train a little bit before testing AMD platforms
"The Socket FM2+ configurations don’t have good power consumption results when overclocked. Thief is a recently released game so we didn’t use it in our tests earlier but you can use the Fritz Chess Benchmark results to compare their power draw with that of LGA1150 platforms. Despite the discrete graphics card, their power consumption is comparable but the Intel Core i5-4670K overclocked to 4.5 GHz is almost twice as fast as its opponent!"
You should really use a lower power supply for a rig that sucks maximum 200W if you want to show us the power efficiency.You are using a 800 W one.
Intel Core i5-4670K is 30% more expensive than the APU you are using and has negligible GPU power (the included GPU being the key of AMD on FM2 platform) .What to say the CPU+ mobo combo price
Your review shows lack of knowledge for AMD hardware.
Just avoid reviewing AMD parts if you hate them.You are to biased.
AMD is all about price perf ratio and since FM2/+ it also goes well in the power efficiency.
5 points from 10 for this review
Gigabyte showed once more that it throttles the most any AMD CPU-s.The APU VRM design it s simply cheap.
