AMD A6-5400K Trinity 3.6GHz

post #1 of 15
Thread Starter 
So, can anyone tell me whether this is a true dual core, or single module? I'm guessing the latter. I'm looking to build a light gaming/htpc rig and no, I don't want to build an Intel.

Its a dual core proccessor.

Yeah, but the new architecture uses modules of two processors that share resources.

I guess I'm wondering whether these low end Trinitys are just improved Llanos.

I think thats the new Piledriver CPU's, these are improved Llanos, with a 25% performance increase. It's a dual core thumb.gif

Trinity uses piledriver architecture. 5400k is one piledriver module, two cores. Llano uses x86 stars cores.

Not sure, as I haven't studied these processors all that much- but what he says is also available on Wiki.



I don't think they are Llano based, as the entire list is covered under "2nd gen Bulldozer" but that's just my 2cents.gif

Edit: Just to add, since all models support all instruction sets, this pretty much rules out rehashed cores, so if they are improved Llano, they are still a completely different die.

Have a Cinebench R 11.5 run. Lets have a look at those scores:)

It Works Both as a Single core and dual core CPU.

FX has the abiltiy to use the Full 4 way Front end and L2 cache when using single thread in a module.

note that when both threads are using in FX currently you can see from 25%-33% loss in each threads speed.
The reason for this is the scheduler changes down to two 2 way decoders for each core with in a module.

Sharing resources that come from similar data shows 10% speed up

you need two different programs to make completely different writes in the register files of the the architecture to loose any speed ups. This so the they don't use the full Front end and L2 cache.

It's one module looks like fun.

Cinebench 11.5r will skew the results as mention early it will use the full front end for the single thread test and then split up on the multi core test making it look weaker then it really is.

if you want True proof of what I'm talking about you need to run another program to stress and split up the front end.

Try running IntelBurnTest ( IBT set to one thread) and Cinebench 11.5r at the same time. Just set he affinity to one core each from a module.

you will see the MP ratio should be around 2.0-2.2 instead of the 1.6 MP that anatech got.

piledriver cores has a slightly improve schedulers so the loss is less then what I said up their that's is for FX.

How about running 3D Mark 11 and checking the physics score. Heard that it's a good yardstick to judge the cpu by.
