Isn’t a big advantage of an accelerator is that its more optimized to do this sort of work than a cpu? This npu is a tiny dot on the Meteor Lake die while the cpus take up a whole tile and accounts for much of the power usage of the soc at any given time.
- wtallis 2y agoI don't think the NPU is tiny, just much more power efficient than the GPU or CPU for the right kind of tasks.
- acdha 2y agoThat’s the idea but it looks like this might not pull it off unless Intel aggressively gives away optimized libraries. If it’s too hard to get to the point where it’s actually competitive, most developers are going to use the faster iGPU.
- touisteur 2y agoYou hit the nail on the head. Software, libraries, dev tools, profiling resources, mindshare... And for Intel, a good deal of maintained interest. For those of us who used and programmed SHAVE cores, to see everything slowly close down behind openvino, no apparent interest from Intel in years, the writing was on the wall. Repeatedly, they taught us: use nothing from Intel except main-mainline x86_64.
- acdha 2y agoWhat’s sad is that I remember the same lesson from Itanium: to preserve a small revenue stream from their compiler and optimized library business, they made almost every benchmark even worse at a time when they most needed businesses to be comfortable switching.
