AMD Ryzen 5 Processors
After more than four years developing AMD's new "Zen" microarchitecture, the beginning of 2017 has seen the retaking of the high-end segment of desktop processors. The chip manufacturer has brought to bear a new, cutting-edge Ryzen processor design that has lived up to all the hopes and expectations of PC enthusiasts. The important mid-range of the series is represented by the Ryzen 5 range of processors, a range that has received universal critical acclaim and impressed with its extremely attractice price-to-performance ratio, particularly for gamers.
The Features of the Ryzen 5 Processors:
- 4 or 6 "Zen" cores with very low Thermal Design Power (TDP)
- 8 or 12 threads thanks to Simultaneous Multithreading (SMT)
- Very high single- and multi-thread performance
- High Base Clock with Precision Boost Turbo function
- Automatic overclocking function (XFR)
- Unlocked multiplier for manual overclocking (unlocked CPU)
- Large unified cache memory: 3 or 2 MB L2 & 16 or 8 MB L3
- Efficient 14 nm FinFET manufacturing process
- AVX2 instruction set extensions for complex vector calculations
- Multiple AES units for fast and reliable data encryption
- Moderne AM4 platform with extensive features
- Supports energy-efficient DDR4-RAM (Dual-Channel)
AMD Ryzen 5 Processors for Gamers, Overclockers & Professionals
The AMD Ryzen 5 processors from the "Summit Ridge" generation come with four or six physical CPU cores which, thanks to Simultaneous Multithreading (SMT), are capable of processing two threads simultaneously meaning that the number of cores is effectively doubled to eight or twelve. Precision Boost adjusts the clock frequency in real time according to the processing load - irrespective of whether this takes place in games or in applications - and increases its frequency in accurate 25 MHz increments while remaining within TDP range.
The chip architecture operates at lower noise levels while producing less heat than any of its predecessors, resulting in drastic improvements in terms of energy efficiency. The impressive performance specifications of Ryzen 5 CPUs demonstrate the extent of the time, research, and development that has been invested. Ryzen 5 CPUs offer very good Instruction Per Clock (IPC) performance in both single-threaded applications as well as highly parallelised multi-thread applications.
Ryzen CPUs are manufactured with a 14 nm FinFET manufacturing process with stapled transistors (also known as 3D transistors). This striking reduction in scale has resulted in space being freed up on the processor die, thereby permitting the integration of a total of 2 MB Level 2 Cache and a full 16 MB Level 3 Cache into the centrepiece of the PC. Due to the intelligently controlled cache buffer and thanks to the "Smart Prefetch" jump-prediction algorithms, Ryzen is capable of ensuring instantaneous data access and swift compute performance.
AMD's Ryzen 5 CPU Overclocking
The AMD Ryzen 5 series of CPUs is equipped with the revolutionary auto-overclocking feature known as Extended Frequency Range (XFR), allowing the processor's frequency to be increased far in excess of its factory-determined limits in respect to maximum boost clocks, as long as sufficient cooling is available. As soon as the CPU's integrated sensors register additional cooling capacity, Ryzen CPUs independently adjust their clock frequencies in accordance with the cooling solution. Direct control on behalf of the user is therefore no longer necessary. Depending on whether CPU temperatures are being maintained by a comparably-small air cooler, a large (dual-) tower cooler, a more capable AiO or custom water cooler, or even extreme liquid cooling options like LN2, XFR affords access to premium- and enthusiast-level clock frequencies tailored to the degree of cooling performance provided.
All AMD Ryzen CPUs are "unlocked" and come with - as was the case with the "Black Editions" and "K" variants of earlier product ranges - an unlocked multiplier that allows overclockers to attain relatively high clock rates in a virtually foolproof manner. The aforementioned overclocks are easily achievable via manual alterations to the BIOS or UEFI, or by means of software tools designed for increasing the maximum factory-set boost clocks. Both an overclocking-friendly chipset such as the AMD X370, B350, or X300, as well as additional 3rd party cooling is necessary.
