Hello,
I'm building an htpc and was wondering what amd CPU would be better for a Htpc? Phenom ii x4 or Athlon ii x4 ?

More about : phenom athlon htpc

For playing back video either will be fine. Actually, a dual core would be fine. If you buying new parts to make the HTPC, then consider AMD's Llano APU series or the Intel Core i3-2100 thru i3-2125 CPUs. Those CPUs have integrated graphic cores which means you don't need to buy a video card.

If you encode your own videos, then the Phenom II would be better. Again, if you are buying new parts, you might want to consider the Core i5-2300, 2310 or 2400 depending on your budget. The Core i5 series offers better video encoding performance than the quad core Phenom II X4 series.

If you are using it in the purist sense of the word HTPC then a llano is purpose built for that.

Neither, llano is the better choice, and you don't need a stand-alone graphics card to do it with.

The Athlon II is a Phenom II without an L3 cache basically, they are almost identical except for that. The lacking L3 cache does lower performance, but not substantially so.

An X3 does well. I found the athlon x2 240 a tad sluggish and replaced it with an x3 445 a year ago and am happy with that. My motherbd has an integrated radeon 4250 that has dedicated memory and handles the video aspects just fine.

My newer build uses an i3-2105 which I find to be even more responsive than the AMD x3. Its integrated hd3000 GPU handles the video just fine also.

No gaming is done on the htpc's.

+1 to all the llano recommendations. The llano APU's from AMD have built in GPU's comparable to decent entry level dedicated graphics and FAR superior to any integrated GPU's intel has to offer. These chips are a great choice for an HTPC lowering cost, voltage/heat/noise and case size all the while providing more power than you would need in an HTPC.

I've done both and didn't have a problem with either. I kind of liked the quad core Phenom II a little better than the athlon. I agree with pop the Athlon seemed a little slow in loading movies but it was still ok.

Lack of a L3 cache woudnt be a bother since your main purpose seems to be building a HTPC. So Athlon is a better one out of these two. But the Ilano processors have better graphics which would help you in video decoding. Im not sure about the editing and transcoding performance of Ilano but Im sure they are much below Intel HD 2000\3000. :)

I'm not quite sure what supersdu means by editing/transcoding performance as this is a task handled by the CPU in which a llano CPU priced equally to an intel will be a quad core CPU vs. a dual core on the intel side and there in clearly more suited to tasks of this nature.

Here is a link to the 3850 APU from AMD, as you can see it is very highly rated.

Here is some info on the 3850 from anandtech.

unless he is refering to ISRT and lucid virtue on the Z68 platform, which is mostly fallacy, never noticed any transcoding/encoding performance gains over a dedicated GPU, at best it was a gimmick.

With more Llano setups coming with Lucid MVP, it makes a basic HTPC setup a sure win. Superior IGP with ample enough CPU crunch.

Either an Athlon II or Phenom II would be plenty, I'd rather use the Athlon II for lower power draw and cooler operation.

Or as others have mentioned if your building new something based on Llano would be better for this task.

Thanks for all your replys! I think I'm look more
Into the Llano ! What is the difference between the A4-A6
And the A8?
Thanks again for all the info!

A6 is a 3 core
A8 is a 4 core

That Review on the 3850 I posted above is a great source of info.

A8 would be your best choice out of all of those if it is in your budget. Cheers.
