On the QCOM Server thing, it need to be remembered that Server isn't a small one-off venture you can enter and leave at whim. Customers will want much more than a "Best in Class" Core. You need serious software, ISV and engineering support available, you need a roadmap, you need to invest into Server specific details (Uncore, Scalability, Cores per Socket, perf/W, etc) and you need a serious and committed roadmap and execution that shows your partners that you won't walk away at anytime.
AMD literally struggled a lot with the latter part, once their Epyc based systems started to make rounds, because people didn't believed they would execute and that Zen was a one-off thing. It took AMD many years for them to create a reliable brand image that eased their way into Server.
QCOM, just like AMD at the time, only has a "Best in Class" core and that's all. If they want to go server, they'll need to execute on a lot of things and it will be a slow and long-term process. They can't enter and leave this space like they did before. So, it remains to be seen if we'll truly see QCOM in server space. Hardware is only part of the solution.
No way, IMO that Exynos will use Mali.
Mali? The recent designs are actually really good but the driver situation is concerning. But I would welcome a big player to try to force their way into WoA and make it so that Arm has to start to give more support towards Mali on WoA.
Seeing possible more entrants in the GPU space for Windows is exciting. Soon we'll have AMD, Nvidia, QCOM and Arm with GPX IPs for Windows. Maybe even Huawei with Maleoon?
