A10-7850K or i7-4770k for computational tasks

Hey,

I was wondering which is the best of the two for computational stuff? Am I correct in thinking that because of the AMD chip supporting HSA, and OpenCL 2.0, that it will perform better in such tasks?

It seems it also supports higher ram speed etc, looking at this comparison?

Thanks in advance :thumbsup:

porter m: The AMD chip is $185 and the Intel chip is $310 so on price alone this is not a fair comparison. I suppose on a few benchmarks the A10 might win but best computational performance overall? I would say easily the Intel 4770k.

BTW, here is a nice review of the A10-7850k:

kaveri has very competitive OCL hardware and a better driver[compared to intel] and it does also have the tensilica dsp block.
 
Depends on the Computation.

For OpenCL the 7850k will be better.

For CPU computation the 4770k will be better. Scientific computation is very limited by FPU, cache, and bandwidth so the 4770k will smoke the 7850k (even the 8350k) in these applications.
 
Is your computation software written for OpenCL? Are you willing to rewrite it?

If you answer no to both, don't even think about it - 4770k.

If it's yes, maybe think about a dedicated gpu as well.

For OpenCL and OpenGL the A10-7850K will almost always be way faster than 4770K.

4770K without a doubt of the 2.

Even for GPU compute you would not buy a Kaveri. You would buy a much cheaper CPU and add a dGPU. And CPU wise Kaveri is nothing more than a glorified dualcore.
 
Why not a Xeon E3 1230? They're cheaper than 4770K and does about the same thing, and probably better at computing.
 
Kaveri wins if your software can actually use its capabilities. Otherwise, you'd be a lot better off with a 4770K. Any current Intel quadcore or better is going to beat Kaveri in CPU performance.
 
Well, the OP specifically asked about HSA and OpenCL. In those applications, Kaveri will be way faster than 4770K.
 
I like how people go off topic all the time. The Kavari is the better CPU just because the i7-4770K doesn't warrant paying $140 more. (I'm an Intel fanboy, by the way.)

Considering the steep price for 7850K. You could basicly recommend a i5 4670K instead.

And CPU wise the 7850K is equal to a dualcore to a fraction of the price. Lets not forget that part.

There is simply no incentive to buy a 7850K.
 
Does your application use HSA or OpenCL?

If it uses HSA get Kaveri.
If it uses OpenCL get i7 4770k and a discrete AMD graphics card, which will be many, many times faster than Kaveri

In ALL other cases, i7 4770k is going to be faster

if if uses opencl use kaveri and a discrete amd card, which will use all the opencl cores [12 CUs apu + n CUs dgpu], which will be faster than a i7 + discrete.

the i7 is faster cpu wise.
 
I can't think of a single app off the top of my head that supports HSA and OpenCL. I'd take the 4770 anyday and use its grunt to smash through any non HSA software. And yes, currently the 7850K is horribly overpriced coming in close to an i5.
 
if its going to be a SFF setup with only the iGPU being used, then yeah, the A10 might make sense.

Otherwise a dedicated GPU will stomp all over either one, and it makes sense to pair it with a more powerful CPU than what the A10 can provide.

Not really; the OP suggested that the AMD offering might be better at "computational stuff" because of the HSA and OpenCL, but since no apps were specifically mentioned, there is no valid basis to make such an assumption.

EDIT: This may be an English language semantics problem; OP, can you please provide some apps that you will run with your intended CPU?

What exactly happens when the APU is mixed with a dGPU? Does the openCL get passed to the dGPU and the APU's GPU sits idle?

This is easy to control with crypto mining, however how are drivers and software handling this? Even a simple website, will it be done on the APU or offloaded to the dGPU?

I dont have knowledge to tell you how it works but I can speculate and assume based on the fact that a few OCL programs will see any compute unit and dish out the work accordingly, an example is Luxrender

MUCH cheaper. This really closes the gap and makes price much less of a differential. This closes the gap to only ~$60-75

The 4770k can cost $5000, it still wouldn't make Kavari the better CPU. In fact, it doesn't matter if you got paid to own Kavari and the 4770 cost $1,000,000 a month to use... Kavari still wouldn't be the better CPU.
