Some CPUs have integrated graphics. Applications that require

Necessity is the mother of invention.

I can max out any CPU and/or GPU easily. Folding at home. Rosetta
at home. Einstein at home.....

Few people care about those applications. Most people who run those
applications are wild-eyed third worlders who can\'t afford \"any CPU
or GPU\" anyway. Whatever gets you through the day...

You continue to make no sense at all. Millions run those applications, some on a little smartphone, some (like a guy I know who works for NASA) with SEVEN graphics cards, watercooled, stacked onto one motherboard. It\'s cooled by a radiator. A central heating radiator. Why would a 3rd worlder spend money running those programs?

Are you sure these are used as graphic cards to drive some display
unit?

They don\'t and I never said they did.

Radio is old hat, gamma and gravity wave are used nowadays.

I do. They have a video interface, you just don\'t have to connect a monitor to them all.

as massively parallel processors. Unfortunately the GPU
instruction set is not well suited for scientific calculations, so the
GPU programming is quite awkward.

It\'s very well suited for astrophysics calculations. Biologists have managed too.

Why are CPUs only about 80W TDP? Can\'t they make ones with three times as many cores that have 250W TDP like graphics cards?

they do and have for years. Here\'s a current one, hope you have some cash

Now show me one from years ago. Where \"years ago\" is a similar
timeframe to when graphics cards got that powerful.

You have a link to the ark site. enter your data for whatever graphic
cards getting powerful means and find your answer.

No, I have an enormous amount of processors to sift through.
