How comes that the fastest desktop CPU's from Intel don't have AVX-512? The Xeon CPU's have AVX-512. Laptop CPU's like i3-8121U have AVX-512. Why not desktop

The Xeon CPU's have AVX-512.
Laptop CPU's like i3-8121U have AVX-512.
Why not desktop too? This has been going on for years.
- jeffbee 6y agoPerhaps this tells us something about the relative size of the high-performance desktop market compared to the market for MacBook Pros, which have Ice Lake CPUs with AVX-512.
- willis936 6y agoWhy speculate? If we take i9s to be considered par equivalents to high-end CPUs we find in MacBook Pros, and the market distribution of cheap to expensive CPUs is similar in both desktop and notebook segments, then we can simply look at earnings reports. https://s21.q4cdn.com/600692695/files/doc_financials/2019/2019-Annual-Report.pdf https://s21.q4cdn.com/600692695/files/doc_financials/2019/20... From page 34: 6% of Intel's Desktop platform volume is $705Mn, so total volume is $11.75Bn. 5% of Intel's Notebook platform volume is $1080Mn, so total volume is $21.6Bn. So the desktop market is slightly larger than half the size of the notebook market, but $12Bn is a lot of money to leave on the table then turn your back to. Especially since an aged microarchitecture threatens all CPU-related revenue streams.
- mastax 6y agoThis is still using the skylake microarchitecture from 2015. I'm sure if Intel were shipping the design they wanted to be shpping it would have AVX512.
- dolphin1986 6y agoBecause the ring bus architecture doesn’t support avx512 but ring bus has better latency which is why many prefer it for gaming or audio production work.
