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.

Daily OverClocks

Time to cranck up the speeds and see what potential this FM2 CPU has for daily users/abusers. At 1.5 Vcore set in the bios we could run the entire test suite at 4600MHz on air. With the help from the AMD FX all in one liquid cooling solution we even got 4.7GHz Madshrimps bench suite stable at 1.56Vcore. We did not include the resuts of the little Intel i3 3225 as it can hardly be overclocked, this by raising the bclock. Max frequency we got out of the little i3 was a mere 3584Mhz.

AMD A10 5800K OC'ed at 4.7GHz
AMD A8 3870K OC'ed at 3.6GHz
AMD 1090T OC'ed at 4GHz (North Bridge 2600MHz)
AMD FX 8150 OC'ed at 4,6GHz (North Bridge 2400MHz)
Intel i5-2500K Oc'ed at 5GHz
Intel i7-2600K OC'ed at 4,5GHz
Intel i7-2700K OC'ed at 5GHz
Intel i5-3570K OC'ed at 4,8GHz
Intel i7-3770K OC'ed at 4,7GHz
Intel i7-970 OC'ed at 4,2GHz, uncore 3200MHz
Intel i7-990X OC'ed at 4,5GHz, uncore 3200MHz
Intel i7-3820 OC'ed at 4,5GHz
Intel i7-3960X OC'ed at 4,5GHz
Intel i7-3930K Oc'ed at 4,5GHz

Typical behaviour, even tough it's advertised as a quad core CPU, it shares the same design as the Zambesi CPUs. Depending on the software used to test it either shines or just limps along. The Fritz chess benchmark is not favouring AMD's current CPU design. Cinebench Release 11.5 gives the A10 a small advantage over the overclocked Llano setup. Keep in mind we are running 1100MHz higher clocks on the A10 CPU, so efficiency is far fetched.

In encoding AMD seemed to have sort off a winner on hand, but again it would only be fair to be able to test the A8 3870 at 4700MHz too, this to compare clock per clock. Once we boost the frequency of the FM2 A10 5800 the encoding power drastically increases. Similar outcome for the integrated benchmark in WinRAR.

If we test the overclocked CPU's with the Nvidia GTX480 in two of my favourite games, we spot that the AMD lineup misses some raw horsepower. The games are enjoyable, there's no problem at all looking at the average frame rates. Yet if we look closer at the minimum framerates versus the Intel ones, we are lacking some punch, yet it all remains perfectly playable.
