AMD Trinity A10 5800K APU Review

CPU by leeghoofd @ 2012-11-21

Who hasn't heard about the following phrase? The Future is Fusion ! Unless you have been living under a rock for the last years, this AMD marketing slogan was pretty much everywhere. AMD wanted to create a platform that was mainly very affordable, where a dedicated graphics card was not a must, while being power efficient, especially for the mobile market and up to the task to satisfy our multimedia, digital desires/needs. One option already existed in the form of an integrated graphic chips solutions on the motherboard. However the latter had non-conforming performance for todays standards. This all lead to the creation of the APU, Accelerated Processing Unit. The first steps to make Fusion a reality. The FM1 socket Llano CPUs was AMD's first succesful try in this new market. As usual the competition caught up, so time for a new revision of the AMD APU. Hello world this is platform Virgo calling... Time to have a look at AMD's latest Trinity socket FM2 APU.

A10 5800K Stock Results

One of the weak sides of the Zambezi architecture was it's single threaded performance. With Piledriver AMD promised to bring us more performance clock per clock. Due to it's far higher clocks speeds versus the Llano 3870K (4200MHz Turbo speed versus 3000MHz) it's slightly faster in SuperPi 1M. However if we test the multi threaded Wprime test we see the Llano CPU come out way faster. Imagine the old FM1 generation at the same clocks as the FM2 A10K ? However let's test the longer versions first before we draw any too early conclusions. Compared to the raw power the Intel CPU's deliver in these two tests, it seems the brand new AMD is a few generations behind. Even in Wprime when comparing the Intel i3-3225, which only has 2 cores and 4 hyperthreaded ones, the A10 5800K just seems slow.

The longer tests even put the brand new A10 5800K in an even worse daylight. The SuperPi 32M goes tragically slow, we did not select the affinity to run on one core, nor specified a particular module. Just pressed run and that was that. Wprime 1024 is luckily on par as with the performance as the shorter Wprime32 test. However trailing the Intel i3-3225 big time.

Bandwith is Intel's Sandy Bridge and Ivy Bridge's middlename. However we spot a huge leap coming from the previous FM1 A8 Llano model. Take note that all these CPU's were tested in a dual channel 1600MHz RAM configuration for all systems, besides the X79 or Socket 2011 models, which are set up in quad channel mode.
