big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4

After Intel’s hybrid CPUs, AMD is preparing its own big.LITTLE scheme that uses a mix of Zen 4 cores and a new Zen 4c variant that will be used in servers but also in laptops. However Zen4c is and at the same time is not a little core. While having much smaller footprint, it is said to be fully architecturally equivalent to the large core, including (almost?) the same performance per 1 MHz. The only little thing about it is clock speed. Read more “big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4” »
