That is all.

With a single core CPU, it's either on or it isn't. With eight weak cores there is more precise control of computing power and electrical power expenditures.

In other words, if your software is efficient enough to handle all of the cores given to it, eight weak cores is better than a quad or dual

The E5 Octa isn't even a "traditional" 8 core design. It's 4 strong + 4 weak. The strong and weak alternate between certain tasks to save power or provide high performance, though I think all 8 can be used when the system needs to.

That is all.

its really 4 cores, the other 4 is power saving cores, and they cant even be used at the same time.
plus, more cores doesnt mean faster.. fx8150 sure as hell isnt faster than a 2700k..

Exynos 5 Octa is four A15 Cores at 1.6Ghz Clock + 4 A7 cores at 1.2Ghz Clock, Snapdragon 600 is 4 Krait 300 at 1.7Ghz in HTC One or 4 Krait 300 at 1.9Ghz in GS4. Which side is faster depend on A15 vs Krait 300 IPC differences.

If your software can use 8 cores its efficient. That I get.

Again, 8 cores on a phone. Completely retarded. Focus on 4 efficient cores with high clock speeds is plenty. You don't need 8 cores to stream youtube. This is gimmicky as it gets.

Most likely Samsung couldn't get a Quad A15 SOC to be energy efficient during light workloads, thus their solution is to shut the A15s off and use A7s at low workload situations.

Thus this Exynos 5 Octa isn't an Octa core, it is 2 sets of Quad cores used for different workloads.

It is not 8 cores - it is 4 pairs of a high speed part and a low voltage "ok" speed counterpart.
It is a dual mode quad, and as overkill in a phone as the current quads.

a15 has been proven to be faster than krait..as said earlier...the extra 4 cores doesnt have any performance benefits..its just there to save power..
the ignornace of people is too much for me to rake in...its a quad core part..and more cores =/= bad
since they always shrink the process, you can get more performance for same amount of power..today's phones arent exactly fast enough yet anyway..so no need to go apecrap over them improving it(and honestly, why hate on improvements?)

Tegra 4 will dominate this year but the power consumption is going to be terrible compared to snapdragon and the rest.
