If a GPU is better at cracking passwords than a CPU, why is the left brain better at mathematics and logical thinking than the right brain? Would it make more sense to interpret maths more creatively to be able to problem solve quicker?

Vague as fuck. Do you want to memorize optimization algorithms or something beyond least squares?

Your predicates aren't well founded

what the literal fuck is wrong with you? are you goddamn 12 years old? The left brain and right brain are connected via the corpus callosum, and you use both of them almost the same (you barely use one more than the other).

>>7643214
to add to this, a GPU has many, many, many, MANy, exponentially many more cores than a CPU.
GPU cores (especially NVIDIA's) are really goo at performing repetitive mathematical tasks.
If anything, the CPU is more "creative" than the GPU in that a CPU can perform exponentially many more DIFFERENT types of tasks that stream processors can.
I can go on forever about this, but I'll leave it here for now.

>>7643172
left brain - right brain dichotomy is mostly bullshit
also your assigning gpu as creative doesn't really make any sense.
>>
>>7643237
i agree
Lehman's terms of this >>7643235
is that the OP has it all backwards.
GPU can literally, physically only calculate.That is all the are good at and all they can do. It's basically a fat, hungry, more specialized version of an ALU.
The CPU is the one that actually interprets the data and figures out what to do with it (according to instructions ofc), then spits it out to the GPU, then the GPU shits a bunch of colors onto a display.

AMD actually hes like 20% more pure computing power per $ iirc, and also they have more cores than nv. thing is they have different instruction set so when it's used for generating graphics some of this power is wasted.

I would like to see some actual benchmarking data to back this us up. But yeah, the guy in the stackexchange post pretty much summed it up. GPUs typically have lots more execution units that can run in parallel. password cracking is basically brute forcing a shit ton of different possibilities with no data dependencies. Hence, it benefits from GPU accelerations. You could probably get way more performance and power efficiency from an FPGA but it would be more difficult to implement.

First of all, the right being the creativity and left being the logical part of the brain is a myth.

No such thing as left or right sided brain. You have both. If you only had one, then you would be severely mentally retarded.

Maths as practiced academically is actually dialectical logic with a specialized symbolic language - ie it is "language" to the brain, not pure calculation. That's why it uses the left hemisphere, and why it is slow. The language aspect is a choke point that creates linearity. The right side does a mindblowing amount of calculation in parallel. That's what creates the "immersiveness" of our subjective experience. It's still a logical deduction from the collective stimulation of the nerves by external and internal objects, but because it's not consciously "audited", it's subjectively instantaneous, and many calculations can be done in parallel and the collective body of their results viewed in parallel as a gestalt or image, rather than as a stream of thought, which is language. This is why, under the influence of psychedelic or deliriant drugs, unreal situations and experiences can be had which are subjectively perceived as fully real - the consciousness is only viewing the (faulty) output of the processes, not the processes themselves.

as far as i know the GPU has a lot more ALU's (Arithmetic/Logic Units) and are better at repetetive work.
-> they are good at doing shit loads of math.

>>7645767
Repetitive simple tasks, and non-serial tasks. Their main strength is parallelization.

>AMD doesn't have CUDA
Yeah, bitcoin miners must be screwed. Oh wait, AMDs had the highest hashrate per watt of any card before Maxwells came out.
>>
>>7643193
GPUs don't have any cache, like a CPU does. Also GPUs aren't specialized CPUs as that would imply that a GPU could replace a CPU as the central processor.
>>
>>7644228
You're the shill, (1) you literally provided no evidence for your argument and (2) Radeon cards have a higher hashrate than Geforce cards for cryptomining. Also, I own a GTX 980, so I am definitely not biased towards AMD.
>>
>>7645790

> GPUs don't have any cache, like a CPU does.

Lacking cache is not a defining trait of GPUness.
Having cache is not a defining trait of CPUness, and is a relatively recent innovation.

> Also GPUs aren't specialized CPUs as that would imply that a GPU could replace a CPU as the central processor.

What do you think "specialized" means?
>>
>>7645790

>gpu's don't have a cache

Huh? I was certain gpu's did have all the functions of a cpu. I always thought that gpu's were like a second computer within a computer, with its own registers and memory.

The only difference was that gpu's were specifically wired for matrix multiplication operations.
Am I wrong?
>>
>>7645800
>Lacking cache is not a defining trait of GPUness
Would it make sense to put caches in a GPU? No, so I believe a lack of cache is a defining feature of the GPU.

>What do you think "specialized" means?
In this case, a replacement for a CPU with lots of cores, and no cache.
>>
>>7645820
Registers and memory, yes. But cache is the intermediate between the two, and it wouldn't make much sense to copy the same data to each core.
>>
>>7645825

I meant to say to the cache of each core.

No such thing as left brain/right brain thinking is spread out evenly, not contained to a dominant hemisphere, the left brain is not better that is just where information is sorted/stored, and vis versa
>>
>>7643193
No it's fucking not. A GPU is a graphics processing unit and a CPU is a computer processing unit. GPU is graphics. CPU completes the main processes of the computer.

FUCKING IDIOTS EVERYWHERE.
still, facts are here:

2 cards launched in June 2015, both for price of 649$ with their pure computing power measured in TFLOPS (single precision):
Radeon R9 Fury X 8601.6
GeForce GTX 980 Ti 5632
so yeah, i was wrong. AMD card is actually 52% FASTER than NV one (also for double precision AMD is 3 TIMES faster than NV)
or maybe it was just nvidia shill?
