Even after working with them for a while, GPUs still feel like cheating. They are just so goddamn good at what they do.
That kind of speed up isn't just a fluke here, it's pretty normal when your work aligns with what a GPU does best.
- pjmlp 9y agoIt is a complete different way of working, but sometimes it just feels like going back to Amiga coding with Blitter and DMA.
- gmueckl 9y agoI've been working with GPUs for many years now and I still get surprised by their performance: some things turn out to be so bloody fast that I initially think that i must do something wrong. Other times, CPU implementations run circles around the GPU for no obvious reason. It's not intuitive and I still have a hard time wrapping my head around how fast these things are when they are at their best.
- roywiggins 9y agoThey're really fast even if you're sort of abusing them. Using fragment shaders to render entire scenes ("two triangle" style) probably wasn't what GPUs were built to do but the technique is awfully effective.
