Hi AMD,

I am trying to verify that AMD A8-5600K is a quad-core right off the bet without any tweaking or unlocking or turning on turbo. Right?

Yes and then no, but it has 4 cores and 4 threads. The chip contains two Piledriver modules which contain two cores each.

To some software this means two cores and four threads, but that is always what it is. Details just look up Piledriver microarchitecture in Wikipedia.

Technically it's a 2 core/ 2x2 threads which AMD calls "4-core"

The A8-5600K is a (4) core APU.

http://www.cpu-world.com/CPUs/Bulldozer/AMD-A8-Series%20A8-5600K.html

Some people have a difficult time understanding that a DUAL CORE module is TWO CORES thus 2x of a Dual Core Module = 4 actual cores, not 2 real cores and 2 virtual cores like Intel CPUs can have.

AMD builds processors based on dual core modules so if you have 2x modules you have a 4 core APU/CPU. If you have 3x modules you have a six core processor. If you have 4x modules you have an 8 core CPU.



-------------------------

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

This thread explains pretty well what about those "cores"

Unfortunately a lot of what you read online is technically half truths or incorrect so most people have no means to understand fact from fiction.

The fact is AMD processors with dual core modules function exactly like two cores per module regardless of the front end fetch, floating point, etc. architecture. While the architecture has room for improvement and steamroller brings some of those improvements, the fact is that the core count that AMD advertises is correct and the CPUs perform as advertised not as 1/2 of the advertised cores.

The "cores" are merely the integer units of the CPU(ALU) - effectively meaning the "cores" are no cores at all.

It would be technically more correct to say it's a CPU with 8/4/2 integer units and there the "multi-core" show stops boldly.

just a blunt marketing gimmick!

 

Here the "8-core" FX showing just 4 modules (cores) on die:

No it's not a marketing gimmick. This is precisely why I said a lot of what is written is incorrect and most PC enthusiasts can't decipher fact from fiction. The cores are in fact actual cores and thus a dual core module is two cores running two ops concurrently, even if some folks don't understand or believe this.

And you are who pretending to be the ultimate FX illuminatus?
