MythBusters feat. NVidia: GPU VS CPU - Mona Lisa PaintBalled

Jamie Hyneman and Adam Savage (from MythBusters) give us a science lesson about the difference between GPU and CPU with an amazing and fun show sponsored by NVidia.

This seems like a much better crowd than the Youtube Live! crowd.

thumbs up if u hear a guy shouting "i love pizza" at 6:56

:D

@123saxon123 Basically the demonstration shows that a CPU renders only one pixel at a time while a GPU renders all of them simultaneously.

Hence Leonardo 1.0 shot one paintball at a time while Leonardo 2.0 shot 1100 paintballs at a time.

This is basically serial processing (CPU-one at a time) and parallel processing (GPU-multiple computations/shots done simultaneously) in explosive terms.

@123saxon123 GPU- Parallel Processing CPU- Serial processing.

@fatandhorny Correct, it has 1 3.2 GHz processor and 7 minor processors, think of the other seven as calculators.

[Jasper2428]

@123saxon123 GPU = Graphics processing unit CPU = Central processing unit.

GPU's have been invented to do graphical operations in which the CPU usually handles.

Get it now?

@123saxon123 well i dont want to be a "know-it-all" but its actually quite a good "metaphor", since a cpu(32bit) is only able to process 32bit = 1pixel at once.

A GPU would be capable of creating more pixels at once.

@ertreri It's not the PS3 that doesn't support Windows, it's the other way around. Windows doesn't support PowerPC-based processors. Also, you're talking about the SPEs, which are SIMD units, not cores. Indeed, six of them are available for games, but the seventh is reserved for XMB, not for the operating system. And finally, Cell is nowhere close to being capable of real-time ray tracing. Even GPUs that are much more powerful can't do that, let alone a $38 single-core chip like Cell.

[fatandhorny]

@ertreri Thinking the Cell is a regular CPU and has 7 cores shows a complete lack of understanding what the Cell actually is - it's architecture is completely different to your standard CPU and it doesn't have cores like your standard CPU. It has one PPE and eight SPE's.

@Theris1337 .... sounds more like he's saying, " i want free stuff!!!!". that would make more sense.... but hey, im just sayin. still funny though. :D

cpu is SLOW lolol
