Sorry but this made my day.

If you're truly above him prove it by not wasting your time on him! People like that aren't worth wasting time on.

I've known many people like that, and it annoyed me that if I had stuck my neck out and said "You are talking some genuine ****!" I would've looked like an even bigger gibbon than him! Just be confident that you know you're right - politely telling him so, with a smile, and eventually he'll find out he was wrong :)

He's not that kind of guy. He'd argue his way till he thinks he's won.

If I told him he was wrong he'd just pull a face thinking i'm talking ****

He sounds just like one of my classmates at college. He says something about whatever we are talking about, I correct him and he keeps on and on and on about how he is right, and then when he knows he is wrong, he just ignores me and acts like he "won". I have no idea what to do XD

I am shocked at how poor this is and how misguided it is.
 
@OP

You should show him this post and he will have no answer to back up his claim;).

I have been doing some reading on PS3 Cell cpu and it seems in single-precision floating point operations (32bit) it is capable of 204.8GFlops. However in double-precision (64bit) it only managed 20.8GFlops although theoretically it is capable of 102.4GFlops.
http://en.wikipedia.org/wiki/Cell_(microprocessor)#Architecture

Now Intel Burn Test and LinX are both Linpack which is a double-precision benchmark program.

My [email protected] is capable of 45GFlops out of a possible 54.4GFlops at this speed in IBT. So it would seem in double-precision my Q6600 beats Cell :D.





However IBM did release PowerXCell 8i which managed 102.4GFlops in double-precision although it is a server cpu and not incorporated in PS3.

The SB i7-2600K is capable of over 120GFlops as it contains AVX instructions which doubles the peak theoretical performance hence SB getting over 100GFlops aswell.

http://www.overclock.net/intel-cpus/869018-intel-amd-gflops-data-thread-looking-59.html#post12049787

So if I am correct Sandy Bridge is faster than PS3 Cell cpu although I don't know how applicable are double precision Flops in gaming or real world usage?

What do you think guys ?:)

If your SandyBridge CPU is at 4.7GHz then theoretically with the inclusion of AVX Instructions which double Flops;

Single-Precision (32 bit): no of cores x Flops per core per cycle x cpu speed = 4 x 16 x 4.7 = 300.8GFlops

Double-precision (64bit): no of cores x Flops per core per cycle x cpu speed = 4 x 8 x 4.7 = 150.4GFlops

https://modelingguru.nasa.gov/message/6475#6475


PS3 Cell Broadband CPU

Single-Precision (32 bit): no of cores (1PPE + 7 SPEs) x Flops per core per cycle x cpu speed = 8 x 8 x 3.2 = 204.8GFlops

Double-precision (64bit): no of cores (1PPE + 7 SPEs) x Flops per core per cycle x cpu speed = 8 x 4 x 3.2 = 102.4GFlops

from Wikipedia

Each PPE can complete two double precision operations per clock cycle using a scalar-fused multiply-add instruction, which translates to 6.4 GFLOPS at 3.2 GHz; or eight single precision operations per clock cycle with a vector fused-multiply-add instruction, which translates to 25.6 GFLOPS at 3.2 GHz

At 3.2 GHz, each SPE gives a theoretical 25.6 GFLOPS of single precision performance

For double-precision floating point operations, as sometimes used in personal computers and often used in scientific computing, Cell performance drops by an order of magnitude, but still reaches 20.8 GFLOPS (1.8 GFLOPS per SPE, 6.4 GFLOPS per PPE). The PowerXCell 8i variant, which was specifically designed for double-precision, reaches 102.4 GFLOPS in double-precision calculations
Click to expand...

Since 1 SPE is disabled, so you have (1PPE + 7SPE) x 25.6GFlops = 204.8GFlops (Theoretical maximum value) in single-precision.

Double-Precision = 102.4GFlops which is basically half of single-precision.

Cell is only good in single-precision (even then it gets beaten by Sandy Bridge) where as it performs poorly in double-precision which is the speciality of PCs. So PC cpus can process very large numbers with more decimal points compared to Cell;). Plus PC cpus are king in multi-tasking.

Hence

SandyBridge destroys Cell:cool:

I realise this is close to becoming a Console vs. PC thread and I don't want to turn it into one, but...

Consoles are pretty good value for money. I mean, you could pick a a PS3 (inc. 160GB HDD and controller) and Crysis 2 for £270.
Now what sort of spec gaming PC could you get for £270 (including Keyboard, mouse, OS and a copy of Crysis 2)?

Are consoles best for high end gaming? No
Are consoles a cheap way to game? I'd say yes

I'm not sure how good Crysis 2 looks on the PS3 or what framerates you'd get, but I'm not sure how good your framerates would be on the £270 PC either.

But as for the PS3 having the fastest CPU, that does seem silly.
 
Wingzero you are an absolute god!

How did you learn about stuff like that!? I'd love to learn hardware in detail :(
Got any links or books I can have a read?

since he said Sandybridge is made to be able to run only 2 programs I decided to open every app on on my computer and open 101 tabs on firefox and play itunes and a vid on youtube. 4gb Starts to limit things :(

I print screened with the video Trollooll playing and showing my cpu usage at 39% with 2 3d games at their menus along with every windows game :D

Going to print the screenshot and your calculations and do some reading up on PPE and SPE and more cell based architecture stuff. :)

And stupot we have interactive whiteboards (a full 60" projector presentation outlining the cell Architecture problems against PC cpus :D )

folding at home? i heard it can be run on a ps3...

so which are you gonna pick to thrash it... cpu.. or gpu....

The 2nd :) pretty sure about it

Today has brought so much light to my life. I'm a network and IT support technician. I run around fixing **** all day. From printers to email problems.

I had a chat with a new Engineering Assessor today about how hes enjoying his time, we got chatting and he asked what I do with my spare time and I answered truthfully. I spend my time learning IT. Which is true, I love learning about hardware and that. Think I might get me a new job :)

I'd love to go into a more hardware based jobs. Maybe building and setting up servers or something ^o^
 
Haha, there is one guy with me in my Uni who constantly argues with me about the 360 being years ahead of pc gaming. I tried explaining to him once, but he is one of those people that will not believe in the truth even if it knocked him in the face.

Really annoying people they are, now whenever he mentions 360 i just walk off or move seats.

Thanks:cool:

Since using Intel Burn Test, I became interested in learning about Floating Point Operations FLOP and I am still learning about it. Although through research I managed to get general understanding of what Floating point number (real number with decimal points) is and how many floating point operations (multiplication,addition, subtraction, division etc) of real numbers are caried out in a cpu cycle per core in computer processors.

It's funny when PS3 was released, you had many people talking about Cell raw power and they often quoted Cell as capable of performing over 200GFlops. What they didn't really highlight was whether it was for single-precision (involving smaller real number with less decimal points) or double-precision (involving larger real number with more decimal points)

Just use wikipedia/internet and there is plenty of info on single-precision, double-precision and cell braodband cpu along with sandy bridge etc.

Although my background is in engineering, periodically I am learning something new in computing department:cool:.
 
I need some books to read through during quiet times at work really.

Got any ideas? anything that talks about hardware and computer architecture in more detail would be nice :)

Thinking about learning a new computer language, can't even imagine doing this kind of job forever!
 
I just google image search key words and it gets it every time :p

Maybe Google knows me too well :p
