64bit colour depth?

[skipper847]

Bored this Sunday morning and was just thinking. Will the Colour depth get any higher then Highest 32Bit-bit or can it get any higher?. You would think 64bit could improve the colour of textures in games even more.

No I am not getting mixed up with 64 bit windows I was just wondering about the colour depth. 8, 16, 32, 64?.

Good question, I would imagine no perceptible difference perhaps so the doubling in processing power needed wouldn't be of any use ?

That is not what the 64 in windows 64bit means. The 64bit is the word length that the processor can handle. it means that it can process a number that is 2^64 long. And it also means that it can access 2^64 bits of memory natively.

This is what you are thinking about Colour Depth.

Colour systems are weird when it comes to the naming.

Artists would love 16 bits per channel, but 8 bit is pretty entrenched. Even 10 bit is pretty hard to come by.

You'd need the combination of a cheap panel and a cheap GPU and killer content. And you'd need to capture all that content in 16-bit colour, so you'd need 16 bit cameras, scanners, and all the rest. That's a big ask.

What you might see is internal handling of colours at greater bit depths for calculation purposes.

That is now what the 64 in windows 64bit means. The 64bit is the word length that the processor can handle. it means that it can process a number that is 2^64 long. And it also means that it can access 2^64 bits of memory natively.

Think you are getting slightly confused here (Windows 64 bit refers to 64bit CPU, not colour depth)

Colour depth is completely independent of CPU and depends on monitor panel quality / GPU power etc etc

New UHD TV's are 10bit colour depth (and some of the cheaper ones are still 8 bit) getting ready for UHD software delivery by 4k BR and other "vendors".

A lot of LCD panels are still 6-bit TN with dithering so even if you have greater colour depth for photos or textures you're still limited by the display.

16 bit panels will take off once HDR TVs are common and don't carry a big price premium, not within the next few years.

I am not confused. that is what i was explaining. I also had a typo, Now should have been not.

And the panels are not 10bit colour depth, they have 10bits per channel, with a 10bit alpha manking the colour depth 40bit.
