Why use CUDA/ OpenCL?

From my encoding experience... CPU is far more reliable and offers a big quantifiable overall IQ increase over OpenCL.

 

Sure i mean my 7770 does render faster than the Phenom II... but it put's out a much larger file in the end because i have to add a much larger data rate to it.

 

So in the end what is the point?

AMD Phenom II B55 Quad / unlocked dual core 4.3ghz CB R15 = CB 422
XFX R9 390 8GB MY RIG: http://uk.pcpartpicker.com/p/MVwQsY
Fastest 7770 on LTT . 3rd Fastest Phenom II Quad on LTT

PCSX2 on AMD CPU? http://linustechtips.com/main/topic/412377-pcsx2-emulator-4096x2160-amd-phenom-ii/#entry5550588

Cause its just faster and better than rendering with CPU, also you can use your computer while rendering without that much stuttering. and it helps a lot in animations and c4d animation work I think

Early 2020 Build : Intel i7 8700k // MSI Krait Z370 // Corsair LPX 8x2 16GB // Aorus 5700 XT // NZXT H500 

Early 2019 Build : Ryzen 2600X // Asus Tuff X470 // G.Skill Trident Z RGB 8x2 16GB // MSI RTX 2070 // NZXT H500 

Late 2017 Build : Intel i7 8700k // Asus Prime Z370-A // G.Skill Trident Z 8x2 16GB // EVGA GTX 1080 Ti  // NZXT S320 Elite 

Late 2015 Build : Intel i7 6700k // Asus Maximus VI Gene Z170 //  Corsair LPX 8x2 16GB // Gigabyte GTX 970 // Corsair Air 240

h.264 48mb file CPU encoded.

OpenCL encode 192mb file (double the data rate)

The compression is different, I imagine. You're using a different method / output file / resolution or some other setting. And regardless, you could also compress the files afterwards as well.

 

A good GPU is order of magnitudes faster in 3D rendering, for starters. Animation is typically 24 frames per second, so if you have a difference of, say, 3 minutes and 10 minutes for a frame, that's going to make a giant difference.
