GPU is like 100 math students
We got a rather interesting comment on the CPU versus GPU war, a war that that was ignited by he head of Nvidia. We were told by sources close to CPU industry that the CPU does the work of five math professors who can do a lot of complex calculations fast, while the GPU is like 100 math students who can do a lot of calculations, but not as complex as the ones the professor can do.
This gets us to another comparison where you have to decide who can do things faster, five math professors or one hundred math students.
This really depends on what kind of data you are computing, but this puts a rather interesting perspective on the GPU versus CPU war. We could see that CUDA and GPGPU can do some computational things faster; but at the same time CPU is predominant in most cases.
The worst thing in this matter is that CPU and GPU are not directly comparable, as you always need a CPU just to be able to run your PC, while GPU can potentially make some things faster but you don’t need it to make the PC work.
That is Nvidia’s biggest problem of them all, as they need to make people care about GPU as roughly 50 percent of PCs still have Intel’s integrated graphics processor to serve as a graphics subsystem, and most people don’t even need anything better than that.
Nvidia’s job is to change this.
