AMD Socket AM4 Processors / CPUs
After more than four years of development, the new "Zen" microarchitecture for desktop processors heralds AMD's starting point in the longer quest to reclaim the high-end desktop segment. The task of living up to all the hopes and expectations of the PC enthusiast crowd has fallen to the manufacturer's cutting-edge processor design: Ryzen. At the tip of the spear with which they intend to (re-)conquer the world of high-performance CPUs stands the Ryzen 7 series that has - thus far - impressed with its multitude of innovative features.
The Features of the Ryzen 7 Processors:
- 8 "Zen" cores with very low Thermal Design Power (TDP)
- 16 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 memory cache: 4 MB L2 & 16 MB L3
- Highly-efficient 14 Nanometer-FinFET manufacturing process
- AVX2 Instruction Set Extension for complex vector calculations
- Multiple AES units for fast, reliable data encryption
- Modern AM4 platform with extensive range of features
- Unterst&Supports energy-efficient DDR4-RAM (Dual-Channel)
AMD Ryzen 7 Processors for Gamers, Enthusiasts and Professionals
The AMD Ryzen 7 processors from the "Summit Ridge" generation come with eight physical CPU cores that, thanks to Simultaneous Multithreading (SMT) are each capable of processing two threads simultaneously. This results in the number of logical cores being doubled with an additional eight virtual cores to make 16 effective cores. Precision Boost also adjust the clock rate in realtime according to the precise needs of the application - irrespective of whether this is against the backdrop of gaming or applications - and the clock rate increases in fine 25 MHz steps while remaining within TDP specifications.
The chip microarchitecture operates at lower temperatures and noise levels than any of its predecssors and has been specially optimised for high clock frequencies, thereby drastically improving energy efficiency. The impressive performance specifications of the Ryzen 7 range of processors show that AMD has effectively utilised the time invested in research and development. Ryzen 7 CPUs offer extremely good Instruction Per Clock (IPC) performance in both classic single-thread applications as well as in parallelised multi-thread applications.
Ryzen CPUs are being manufactured utilising the new 14 nm FinFET process with stacked transistors (also known as 3D transistors). The massive reduction in the scale of components enables the inclusion of a total of 4 MB L2 Cache and a full 16 MB Level 3 Cache onto the processor die. Intelligently controlled cache buffers and "Smart Prefetch" algorithms enable the highly-efficient branch prediction for flawlessly smooth data access.
Overclocking Ryzen 7 Processors
AMD's Ryzen 7-CPUs are equipped with a revolutionary automatic-overclocking feature known as Extended Frequency Range (XFR) which is capable of drastically increasing the processor's clock frequency significantly higher than the factory default, provided sufficient cooling is available. As soon as the processor's integrated sensors detect additional cooling capacity, a Ryzen CPU will independently adjust its clock rates according to capacity of the installed cooler. This means that the active user intervention is not necessary. Depending on whether the processor is bundled with a comparatively small boxed-cooler, a larger (dual-) tower cooler, more performance-oriented AiO coolers, custom water cooling or even extreme liquid (LN2) cooling, XFR affords users unlimited clock frequencies in the premium and enthusiast ranges depending on the cooling performance.
As an aside all AMD Ryzen CPUs arrive "unlocked" and are available, as was the case in models from times paste such as the "Black Editions" and "K"-variants, with unlocked multipliers to allow overclockers to reach relatively high clock frequencies with ease and manually via the BIOS or UEFI, or by way of software tools that come with their respective motherboard such as the X370, B350 or X300 series. Adequate cooling must be provided in order to ensure maximise increases in clock frequencies.
Ryzen 5 Processors
Featuring the exact same feature set as the AMD Ryzen 7 CPUs, AMD’s Ryzen 5 series of processors also deliver amazing performance. Consisting of Quad Core and Six Core designs as standard, both with Simultaneous Multithreading technology, Ryzen 5 CPUs are unlocked and ready for overclocking - taking the already incredible high clock speeds to a new measurement of performance. Proving to be highly efficient in power-consumption and energy management when increasing clock speeds and voltages for additional performance, Ryzen 5 sets a new standard for Quad Core CPUs as the bare minimum for gamers, with SMT taking things that much further.
Where software and game engines specifically designed to take advantage of multiple cores and threads will demonstrate the maximum performance offered by Ryzen 5 CPUs, gamers can expect a dramatic increase in performance compared to prior generation processors thanks to the architectural improvements of the CPU design. These advancements in Multi-threaded compute bold well for the future of the Ryzen series of processors. Built from the ground-up both in terms of the physical makeup of the CPU and the benefits being shown in modern software suites - as well as game engines, Ryzen 5 processors will continue to see drastic optimisations as time goes on, with the latest software taking full advantage of the Multi-threaded design.
