Re: Arm announcing they'll pull Qualcomm's Arm license in 60 days

1. I don't think either of them are 'morally' correct in how they're going about things wrt licensing

2. RISC-V is not a viable replacement for Arm in mobile/desktop. 5-10 years off *with* massive investment.

@geerlingguy I'd be curious to hear how, if at all loongarch plays into everything. It seems very undercovered in my media circles

@geerlingguy can you explain why riscv can’t just be the exact same in terms of performance as arm?

Most of the ip blocks and general architecture design theory must be shared right?

Edit: I mean obviously something is the problem, I’m curious what.

@pelefant @geerlingguy risc-v is few years old, right?

And cores are compared to Arm Cortex-A55. The lowest sensible one.

Not even years old Cortex-A76. Nor Neoverse-N1.

You want to fight Arm? Be on par with Neoverse-N2. With SVE, virtualization, working EL(1-3).

And boot Linux and BSD out of the box.

Without it you are only weak pretender.

@geerlingguy I'm glad I didn't pull the trigger on that snapdragon laptop... I'll keep limping along on x86_64 for now πŸ˜…

@solarisfire @geerlingguy x86 will continue to have the most native software support for awhile. I think 'limping along' is a bit of an exaggeration lol.

@geerlingguy I thought it was just their license to use their chip-designer software to expand their feature set of their Oryon ARM line.
