Thin and Light AMD Ryzen 7040U ‘Phoenix’ Gets You Ahead

In May, AMD introduced the Ryzen 7040U series of thin and light notebook CPUs, codenamed ‘Phoenix

A few months later, AMD introduces two more Ryzen 7040U processors. However, these chips use their smaller, optimized Zen 4c cores

The first of two new Ryzen 7040U processors with Zen 4c is the Ryzen 5 7545U, which has similar specs to the 7540U For more details visit govindhtech.com

At the launch of Bergamo, AMD explained that the ‘c’ in Zen 4c stands for ‘Cloud,’ and it’s interesting that AMD chose to integrate Zen 4c in a low-end consumer segment

Understanding the technicalities is crucial given AMD’s strategic decision to bring Zen 4c-based parts to consumers with the Ryzen 7040U series

On TSMC’s 5nm process, a conventional Zen 4 core and L2 cache have an area of 3.84 mm², similar to AMD’s initial Zen 4c EPYC chips

AMD went both ways with EPYC server designs. Due to their higher density/smaller size, the EYPC 97×4 ‘Bergamo’ chips have up to 128 Zen 4c cores, 32 more than the top EPYC 9004 Genona chips

All of AMD’s disclosures suggest Zen 4c won’t clock above 3GHz, as expected

Zen 4c is unique in offering identical IPC to Zen 4, but AMD is hurting its customers by ignoring the differences
