AMD challenges Intel with new CPU architecture for laptops

According to GearRice , the Zen 4C architecture that AMD introduced is the ultra-portable laptop market, or ultrabook. With 2 new CPUs including Ryzen 5 7545U and Ryzen 3 7440U, AMD promises to take full advantage of the big.LITTLE technology applied by Intel without any disadvantages.

The new architecture will be fully compatible with future AMD mobile game consoles.

AMD also revealed that this new architecture has been implemented on the Z1 version of the Asus ROG Ally that was launched a few weeks ago. It will be fully compatible with the Ryzen CPU-powered mobile gaming consoles that AMD introduces in the future.

The biggest thing about this architecture is the Zen 4C core, which is a 35% smaller version of the Zen 4 core. According to AMD, these new cores deliver the same number of instructions per cycle (IPC) but reduce power consumption to under 15W. Their smaller size also allows them to fit more instructions on the integrated circuit.

The Zen 4 cores perform better at 20W+, offer higher peak frequencies, and are optimized for single-threaded tasks. AMD claims the two cores are identical in instruction set, cache, and even latency.

Zen 4C is smaller in size than Zen 4

The arrival of Zen 4C shows that AMD is aiming at Intel's hybrid architecture processors - the company has introduced high-performance cores combined with low-power cores starting with the 12th generation Core CPUs (Alder Lake), with fundamental differences between the two types of cores.

With Zen 4C, AMD doesn't differentiate between the two core types as both offer the same level of performance at the same frequency. Furthermore, unlike Intel and Thread Director, AMD just uses the operating system's scheduler to automatically assign a specific task to a specific core.

Currently, AMD is integrating this new architecture into the Ryzen 5 7545U and Ryzen 3 7440U ultrabook processors and the company will likely deploy it to the remaining products in 2024.
