AMD has announced its new 4000-series mobile APUs at CES2020.
The new 4000 series chips are built on the Zen 2 architecture using AMD’s 7nm FinFET process. They have more cores, a higher operating frequency, and more powerful integrated GPUs compared to their predecessors.
|Model||Cores/Threads||cTDP(Watts)||Boost/Base Frequency||GPU Cores||L2/L3 Cache (MB)|
|AMD Ryzen™ 7 4800H||8C/16T||45W||Up to 4.2 / 2.9 GHz||7||12|
|AMD Ryzen™ 5 4600H||6C/12T||45W||Up to 4.0 / 3.0 GHz||6||11|
|AMD Ryzen™ 7 4800U||8C/16T||15W||Up to 4.2 / 1.8 GHz||8||12|
|AMD Ryzen™ 7 4700U||8C/8T||15W||Up to 4.1 / 2.0 GHz||7||12|
|AMD Ryzen™ 5 4600U||6C/12T||15W||Up to 4.0 / 2.1 GHz||6||11|
|AMD Ryzen™ 5 4500U||6C/6T||15W||Up to 4.0 / 2.3 GHz||6||11|
|AMD Ryzen™ 3 4300U||4C/4T||15W||Up to 3.7 / 2.7 GHz||5||6|
These new APUs are designed similarly to AMD’s desktop processors, with eight cores split between two CCX units communicating over the infinity fabric. As a result, the new 4000 series chips now have more L3 cache and support faster memory of up to 4266MHz.
These new mobile APUs also support AMD SmartShift technology, which dynamically transfers power from the Ryzen processor to the Radeon Graphics and vice versa to give users an extra boost in performance to whichever component is being leveraged the most.
