Is the Human Brain the Fastest Cpu

[hergieburbur]

therefore a cpu cannot be stupid. - True or FALSE?

If you want to get into semantics:

"That new dual core chip is stupid fast."

I once was told by a math teacher that the scientific calculators we were using were stupid because they had have the numbers typed into them opposite of what's normally done. First thing that came to mind what "stupid programmers then."

A CPU being stupid? Nah. It's only it's strengths lie in other places.

What did he consider the way its normally done? I've had to program (assembly code, REAL programming there) chips to act as calculators in standard (infix), prefix, and postfix (Reverse Polish) notation for various school projects. All are valid means, and all have their advantages and disadvantages from a computing standpoint.

This also can also serve as another comparison between the brain and a CPU. For a standard mathematical equation (infix), say 5*(3+4), we can immediately go to the innermost parenthesis and work outward, whereas a CPU (more calculator or computer), must read the entire expression before beginning calculation.

On the other hand, postfix is more efficient from a calculator standpoint. The same expression as above would now be 534+*, which is much more difficult for a person to read than a computer, but the computer can begin processing as soon as it reads the first operator, while it is still reading in the rest of the equation.

For certain applications, postfix calculators are considered superior to normal calculators.

THNX TO ALL FOR Keeping this topic alive for sooo long.

You know what? Even though cpu's are dumb, i still love 'em!

Cpu's have come a long way:

Better prosthetics

Computer Surgery on the human body

Advanced Automation in manufacturing

Advanced Testing in all the science fields

Advanced Detection

WE still have a long, long way to go. (GO LUKE!)

CPu's will always be stupid until they can integrate the software and
hardware into one unit just as the brain is with the human body.

To clarify, my second thought was "Stupid teacher." :lol:

It surprising to me how many teachers teach this stuff with a less than full or sometimes even adequate understanding of the subject matter.

I agree fully. I spent endless hours in high school teaching my hot biology professoress some very basic positions! :lol:

Hey, do you have any idea how many positions are in the Kama Sutra alone? That book took two semesters to get through... even one minute at a time! :lol:

The human brain contains approximately 100 billion neurons which operates at a frequenzy of 200Hz each. The total speed is thus 20THz compared to the 4GHz of a regular processor. The brain is therefore 5000 times faster than a processor. A processor uses on average 4 steps to complete an operation which yields a work capacity of 1Gflops. That process is limited to add, subtract, multiply and divide and is only 64 bit wide. The human brain can be much wider than 64 bit and has a lot of other functions such as moving a bodypart in three dimensions. In addition to that the human brain usually only stores and retrieves information. It rarely processes it. The CPU on the other hand always processes the information, as it cannot do pattern matching, as it is static and not dynamic as the brain. Once a dynamic optical CPU is being manufactured, AI will be a possibility. And the robots receiving such brains will be MUCH more intelligent and brighter than us.

 

[jamiepotter]

This is utterly retarded. Where do you start?

1. We don't know how many 'operations' a single neuron performs, because we don't know what the input _represents_, and we don't know what the output _represents_. The '200 hz' figure you appear to have plucked from thin air would, even it did mean something, not refer to raw processing speed as a CPU's frequency would.
2. Same point really: the brain does not use binary, tertiary or any other simple code! The two aren't directly comparable.
3. Moving a bodypart also requires muscles. We are inclined to think it all is controlled in the brain, but this is actually incorrect. A lot of muscular control is carried out elsewhere.

BUT BIGGEST OF ALL:

4. How can you simply multiply the 'processing speed' of each neuron in order to get the overall speed? Do you know how they operate simultaneously? No. You haven't got a clue.

Stop being a retard and stick to computers, where you can spout geetistics at people willy nilly. Leave speculation about artificial intelligence to people with intelligence.

Tone down the iciness newbie. This entire subject is conjecture.

Worst-post yet.

1) There is no accurate measure of the number of neurons in the human brain. It's all estimations.

2) You're assuming that the brain uses all neurons simulataneously. The brain actually only uses a small percent at any given time.

3) A CPU operates at a set frequency. Neurons are action/reaction-based. The frequency at which they operate can be measured with Brain wave scans, but they don't process "commands per second". You can't compare brain frequency with CPU frequency.

4) A CPU has a bus in which data is transferred (32 or 64 bits, typically). A neuron has only one analogous output, and usually have hundreds or thousands of inputs. Moreover, 1 Hz in the brain merely means a neuron has fired, and that just means that part of a much larger equation has been solved. 1 CPU Hz could mean 6 or 7 different operations have executed (Such as add/subtract/fetch/store/etc).

4) AI has nothing to do with the processor type (optical or otherwise). As stated earlier, a Neural network chip has already been manufactured, and AI still does not exist.


You managed to cram the most amount of BS into a single post of anyone here. Congrats.

This entire subject is conjecture.

There are hearing research studies that show the human ear/brain has impressive bandwidth*. The accuracy the ear/brain time response estimates are up to debate but given the quality of measurements being made, "conjecture" is just not a fair assessment.

*: although I doubt they compete with the best CPUs and GPUs

 

[clue69less]

1) There is no accurate measure of the number of neurons in the human brain. It's all estimations.

But the estimates are close enough, probably within 20% or so.

2) You're assuming that the brain uses all neurons simulataneously. The brain actually only uses a small percent at any given time.

For sure. Einstein estimated 1/50,000th as a upper bound but I don't remember what he was basing that on.

3) A CPU operates at a set frequency.

Not always.

I second that Whizzard!

and a robot receving an optical dynamic cpu will never be smarter than me.

i could tie it with a rope, to my bumper and then it would ask me what am i doin? as i am driving down the road, i tell it hey! Ever seen Road kill?

the robot responds "no"...so then i show it.

But i may not do that to a female robot...i love females

Your the first person i've ever seen on this forum, be one star'd for being a weirdo perv

 

[PC_Side_Line]

vett guy, you show us your intelligence, which appears to be nil.

have u ever seen "nil" ?

Cup some air with your fist, then measure the volume of air inside ur fist, take that measurement and add 1, you will find it is equal to the size of ur brain.

 

[dasickninja]

.... Lame.

 

[corvetteguy]

Why are you insulting me? I didn't insult you, i just pointed out a fact. Most people get one star'd for saying something stupid, or wrong, or insulting... you got one star'd for being in love with a robot. :?

Don't mind him, he uses 1024x768.

When the debate about "bran vs. cpu" comes into play I right away think:

That a CPU will beat a brain in how many operations it can do in a given time frame.

However, I also that think a brain can do anything a CPU can, and with infinite more effeciency.

I think of a CPU being incredibly systematic, in that, if one part of a super long equation is "smudged" and interepreted wrong the whole equation is FUBAR. However, when then human brain takes a look at it, it can problem solve, it can find easier steps, different formulas.

This is all rather general and talking about math, but I think the same applies in any situation where cpu vs. brain comes into play.

Granted none of what I say is very true, that's just what goes through my mind when I think "CPU vs Brain"

"be one star'd for being a weirdo perv"

OK VETTE GUY, I'll take the ONE STAR, BUT YOU CAN KEEP THE "WEIRDO PERV".

take the "WEIRDO PERV" PART AND SHUV IT WHERE THE SUN DON't SHINE!

Wow, someone woke up on the wrong side of the roboprostitute.

Seriously you seem very defensive about being called a perv.

And btw, I didn't one star you, i just laughed that someone else did. But maybe i was wrong about the reason, maybe you DID say something stupid, and not perverted, and i was giving you too much credit afterall. :roll:

 

[PC_Side_Line]

hey vett guy: LMAO!! I drive a 2006 Bentley Continental, not just anyone can buy one of those.

Anytime u wanna take ur vette against my Bentley, hey just let me know!

Or what u could do is send me an email and ask for an invite to my CA pc store

I'll pay your first class roundtrip flight to CA, have a limo pick u up, and then take you on a tour of our huge facility! I'll even pay your hotel stay.

sSo how about it?

Hey i just had another idea, I'll send a 1st class car shipping co to come get u and your vehicle, then you can challenge me on my new test track behind our huge facility! It has room for 6 cars wide and 2 miles oval.
