The whole thing felt they were milking it to last 90min.
But the part where they compared their new GPU accelerated ray-tracing to be 4x faster than software ray-tracing was the most hilarious part. I thought software rendering was a thing that mostly stayed in the 90s, but apparently I was wrong enough that even deserved to be mentioned in a multi-million dollar Apple presentation.
New iPhone, better than the old one. OK cool.
- ykl 3y agoRay tracing has been 100% software (as in, either entirely on the CPU or implemented in shader code or CUDA/OpenCL on the GPU) up until 2018, which is when the first hardware-accelerated ray tracing GPUs became widely available.
- PedroBatista 3y agoThat's why ray-tracing in games was not a thing up until 2018. The context is games, which is what they've shown on the presentation to sell us the new iPhone.
- xp84 3y agoI also thought that was odd, with the 8fps on the left. Like, what iOS game are people playing with software raytracing at 8fps?
- GpuIsLife 3y agoYou may be interested to know that Unreal Engine’s Nanite technology uses (mostly) software rasterisation.
- jonplackett 3y agoNanite isn't raytracing though, or even rendering. I think it's more like a pre-render thing to reduce polygon count.
- superb_dev 3y agoNanite has a large pre-render step, but it also changes the rendering quite significantly. (Which in some cases includes a software rasterizer running on the GPU) This is a really good deep dive if you’re interested: https://youtu.be/eviSykqSUUw?si=Vaj8pngU2Bug5LJX https://youtu.be/eviSykqSUUw?si=Vaj8pngU2Bug5LJX
