What're the chances Apple puts ryzen into their lineup?

Zero.

While the performance of Ryzen is pretty good, the overall power consumption and efficiency (idle, semi-load and load) i still no where near Intel. They won't kill 2-3 hour battery life on Macbooks for a AMD CPU.

They could bifurcate their lineup and put ryzen in the desktops or is that silly too?

Looking at previous lineups, they tend to use the same chips for a generation. E.g. when they switched from AMD GPUs to Nvidia, they did it on all products.

For editing, you want to use the highest possible starting bandwidth (sampling rate * bit width) because every intermediate edit and calculation leads to round-off and other errors. You also need them to be WAVs or some other raw format since you cause minor errors every time you compress + decompress something, not to mention the performance loss. It's the same rationale for doing calculations in full 80-bit or 64-b…

Would using fixed-point arithmetic[1] help with these issues at all? [1] - https://en.wikipedia.org/wiki/Fixed-point_arithmetic

Fixed-point arithmetic essentially gives you more resolution at the cost of not having a dynamic range, so in practice you reduce some round-off errors, but overflow errors are much more likely. Overflow ends up as saturation in the context of audio editing and usually sounds like really bad clipping.

In practice, fixed-point or floating-point is better depends on the operation you plan to use and whether you have a good idea whether you'll be able to stay in a fixed range ahead of time [1].

[1] The loss of 'footroom bits' corresponds to the extra resolution lost whenever the FP mantissa increases - http://www.tvtechnology.com/audio/0014/fixedpoint-vs-floatin...

Just because someone can afford to rent a $30,000 camera doesn't necessarily mean they have unlimited cash to burn on other things.

No, but the difference between i7 and Xeon is significantly less than what you'd have to pay for that extra RAM. We're talking O($100).

So O($1)?

If you were thinking of this as being a cheap CPU for a GPU training rig. It only has 24 PCI Express lanes. It might be better to stick with Xeon CPUs because most have 40 lanes.

Thanks for that. Was thinking about building a similar build I current have which uses a 5960X for the 40 lanes.

It's about $2000/week to rent an IQ180. If you can afford the rental price, you can afford a computer to process the images.

thats not how money works. Just because you can afford one expensive luxury, doesnt mean you can afford all the other expensive stuff. Sometimes you do sacrifice all the other thing to get that one important expensive stuff
