1.5GHz, oooof... I guess they really need to catch up on the GHz front, not only the micro-architecture. Once they are in the 5GHz range, we will see how far the micro-architectures and compilers have to go.
- brucehoult 4y ago5-6 GHz is a party trick of low core count CPUs (e.g. 4 or 8 cores) that use 250+ W of power to get less than twice the performance they can get at 25 W. There is a sixty four core OoO RISC-V chip (SG2042) being demoed on a dev board in the last weeks. It runs at 2.0 GHz and has quite a bit of aggregate performance, at lower energy usage than an 8 core i9 running at 6 GHz.
- sylware 4y agoAAA games want raw thread performance more than a huge core count. I am afraid, but the GHz of RISC-V core for high performance desktop will have to go significantly higher. That said, for self-hosted servers, and even some servers, RISC-V may already be ready for prime time.
