With the Ryzen processors, AMD has introduced extra auto-overclocking features: [5] Precision Boost tries to run the processor at the highest frequency allowed at any moment, constrained by cooling and power supply. It changes frequency in 25 MHz increments. Extended Frequency Range unlocks default boost ranges for systems with better cooling.
The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
These adjustments provide the two common methods of overclocking and underclocking a computer, perhaps combined with some adjustment of CPU or memory voltages (changing oscillator crystals occurs only rarely); note that careless overclocking can cause damage to a CPU or other component due to overheating or even voltage breakdown.
The Zen 5-based Ryzen 7 9800X3D has a 500 MHz increased base frequency over the Zen 4-based Ryzen 7 7800X3D and allows overclocking for the first time. [ 28 ] Ryzen AI 300 APUs, codenamed "Strix Point", features 24 MB of total L3 cache which is split into two separate cache arrays. 16 MB of dedicated L3 cache is shared the 4 Zen 5 cores and 8 ...
[5] [6] This is surpassed by the CPU-Z overclocking record for the highest CPU clock rate at 8.79433 GHz with an AMD FX-8350 Piledriver-based chip bathed in LN2, achieved in November 2012. [7] [8] It is also surpassed by the slightly slower AMD FX-8370 overclocked to 8.72 GHz which tops off the HWBOT frequency rankings.
Ryzen uses the "Zen" CPU microarchitecture, a redesign that returned AMD to the high-end CPU market after a decade of near-total absence since 2006. [5] AMD's primary competitor, Intel, had largely dominated this market segment starting from the 2006 release of their Core microarchitecture and the Core 2 Duo. [6]
But a modern CPU (having overclocking potential) can work at 2.5 GHz (even if it is designed to work at 2 GHz) flawlessly without giving any problem of stability. To keep running overclocked CPU at 2.5 GHz or even at higher speeds (by increasing FSB) we need to slow down memory clock so as to achieve a stable system.
The Ryzen family is an x86-64 microprocessor family from AMD, based on the Zen microarchitecture.The Ryzen lineup includes Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper with up to 96 cores.
