AMD Formally Launches Ryzen 5 7545U Processor with Zen 4c
AMD has introduced the Ryzen 5 7545U processor as a part of the Ryzen 7040U family, which is its bestselling GPU, featuring the Zen 4c architecture, a variant derived from the Zen 4 design. This new architectural iteration, termed Zen 4c, shares similarities with Zen 4 but focuses on optimising core density, resulting in reduced die space consumption. The primary benefits of this architecture include accommodating more cores and enhancing power efficiency, as AMD outlines its objectives for Zen 4c. Zen 4c’s key design characteristics are notable, with a Zen 4 core occupying 3.84mm2 of die space, while a Zen 4c core requires only about 2.48mm2. This reduction in size amounts to approximately 35 percent less area. Zen 4c utilises half the L3 cache compared to Zen 4, but the primary reason behind its space-saving capability is the lower maximum clock speed. This reduced frequency mitigates interference and power leakage, enabling the chipmaker to optimise the core layout for density. The increased density of Zen 4c contributes to better latency and heightened power efficiency. AMD aims to retain the same instruction set and IPC as Zen 4 while using less power, ultimately delivering superior performance at power levels below 15W. Key specifications of the AMD Ryzen 5 7545U: Manufactured on TSMC’s 5nm node. Comprises 2x Zen 4 cores and 4x Zen 4c cores. Prioritizes Zen 4 cores in the OS scheduler to achieve a higher absolute frequency. Offers a total of 6 cores and 12 threads. Supports a maximum clock speed of 4.9GHz and a base clock speed of 3.2GHz. Operates within a 15-30 TDP (Thermal Design Power) range. Equipped with a Radeon 740M integrated GPU for graphics processing. AMD’s strategy involves deploying smaller Zen 4c cores in premium laptops with increased core counts, as well as entry-level laptops, where these cores provide the same IPC but with a more compact design. As of now, AMD has not disclosed specific details regarding the availability and pricing of the new Ryzen 5 7545U processor.
