Today, November 2, AMD introduced the first ever mobile processors with combined Zen 4 and Zen 4c cores. Thus, the company supported the modern trend towards hybrid architecture. We are talking about the Ryzen 5 7545U and Ryzen 3 7440U models, which expanded the Ryzen 7040U series.
The AMD Ryzen 5 7545U processor has two Zen 4 cores and four Zen 4c cores. The former are an analogue of Intel’s P-cores, the latter are an analogue of E-cores. But unlike the architecture proposed by Intel, AMD’s Zen 4 and Zen 4c cores support multi-threading. The processor operates at frequencies up to 4.9 GHz, and the third-level L3 cache is 16 MB.
The AMD Ryzen 3 7440U has fewer cores: one Zen 4 and three Zen 4c. The processor clock speed is 4.7 GHz, and the L3 cache memory is 8 MB. Both models consume 30 W of electricity. The graphics are handled by a stripped-down graphics core based on the RDNA 3 architecture – AMD Radeon 740M, operating at 2.5 GHz.
AMD says that Zen 4 cores in chips with a hybrid architecture are optimized for single-threaded workloads, while Zen 4c, on the contrary, is optimized for multi-threaded workloads. At the same time, Zen 4c shows higher performance when it comes to extremely low power consumption – up to 10 W.
In the foreseeable future, such processors can be seen in office laptops with an emphasis on autonomy. However, the company did not say when the first devices based on AMD hybrid processors will appear on the market.
