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

[2is]

2 kaveri apus are most definitely better than 1 4770k, do you understand what multithreading is?

Please link me the dual socket Kavari motherboards you're using.

If you want OpenCL, a $50 GPU will perform better than a $500 CPU.

Not really. $50 GPU is what? used 6750?

Even $120 a8-7600 beats dGPU.

You could argue kaveri is weak for running handbrake or single-thread CB, but opencl? It is kaveri's strongest side. Hard not to recommend it.

Thanks for the reminder, I actually need to order a few switches

my apologies for answering your snide question with a snide answer :sneaky: . Just network two motherboards and voila, 2 kaveri apus!

The impracticality of your comment triggered my snide question. In other words, you started it.

But I really did need to buy some switches, though I need PoE variants, still... You reminded me and I thank you for it.

impractical and unfeasible but not impossible.

and you're welcome.

The OP still has not given specific examples of "computational stuff."

You owe me a new keyboard. Mine is now covered in coffee.

Hah, yeah. Or whether or not it's going to be something they get paid to do (which is a fairly big deal).

High performance right now is Intel CPU + AMD or Nvidia GPU (such as 290X or 780ti depending on your needs for GPU abilities).

Value? Then you have to get specific about what exact OS, apps, and performance target you're looking for. OP just dropped a vague topic on the floor and walked out.

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:

Btw, that site is broken.

The 4770K doesn't have 1MB L2 cache (LOL), it has 8MB, and it doesn't have a ram limit at 1600. I run 2400 on my both my 3770K and 4770, and also ran it with no issues with my FX6350.

Edit : what the hell, lol. That site does the same thing when you bring that matchup together.

Here's the correct specs for the 4770K : http://ark.intel.com/products/75123/intel-core-i7-4770k-processor-8m-cache-up-to-3_90-ghz

Note, the RAM speeds of both AMD and Intel CPUs are officially way lower than they are in reality due to the JEDEC standards being glacially slow to clear. Rest assured you can run DDR3-2400 (and even beyond depending on circumstances) on the AMD and Intel CPUs available today in most cases.

Actually, Core i7 4770K has 1MB L2 Cache (256kb per core). It also has 8MB of L3 Cache (Shared between all 4 cores).

Intel officially only supports up to 1600MHz memory for the Core i7 4770K. AMD Officially supports up to 2133MHz for the Kaveri lineup.

That's the thing though, LLC cache is not exactly like the L3 cache of old, it's speed is at the processor clock speed :

And official memory support is beyond retarded. I know for a fact you can run 2400 on even the A8, and use it myself on SB, IB, HW, and Vishera builds.

Notice anything about the CPUs used?

 

[Arkaign]

http://www.phoronix.com/scan.php?page=article&item=amd_ddr3_2400mhz&num=1

A10 w/DDR3-2400

"There were near-linear performance improvements in some of the system benchmarks when scaling up to DDR3-2400MHz"

Best thing to do with 'Official' memory speeds is to roll your eyes at it.

 

[AtenRa]

Using an unofficial Memory means you are operating outside of the manufacturer specifications and thus you void the guaranty. It is the same thing as Overclocking even without changing the voltage.

Just a reminder.

 

[Slomo4shO]

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.

I think Einstein sums up this post quite accurately:

Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.

The price for the 7850 isn't where it is intentionally. AMD prices their products based on the same factors as everyone else.
