AMD Ryzen Processors

AMD’s CPUs for desktop PCs based on the Zen architecture are known as Ryzen. Epyc is the name given to the Zen server CPUs.

The first generation began in 2017 with a string of noteworthy victories that erased the previous years’ bulldozer blasphemy. Above all, having more cores than the competitors gave the desktop PC industry a fresh lease of life. The AMD Ryzen processors use the AM4 socket, which supports DDR4 memory. Pin compatibility exists with all prior CPUs.

AMD released the second generation in the spring of 2018. The Ryzen 2000 increased clock speed owing to 12nm production and internal advancements, closing the gap with Intel even more.

The third generation was released in July of this year. For the first time, the Ryzen 3000 outperformed Intel at the same clock speed. With the addition of sophisticated 7 nm fabrication cores, certain models could no longer be avoided. In addition to the 12 cores for the AM4 socket, 16 cores have been added, bringing the mid-range platform up to par with the high-end market.

The Ryzen 4000, the first model to be released in laptop PCs, will debut in 2020. The code name for the APU is Renoir.


The AMD Ryzen Series is discussed in this video.

AMD’s Ryzen CPUs are a low-cost alternative to Intel CPUs in many circumstances, and they’re particularly popular among gamers. The price/performance ratio is favorable, and the platform’s kinks have been substantially smoothed out. It’s critical to choose the proper motherboard when building an AMD computer. The chipset is its most important component, and AMD presently supplies six distinct chipsets to mainboard makers.

Chipsets are categorized into three groups. According to AMD, “A” chipsets are for beginners, whereas “B” chipsets are for the middle class. The X series is designed for the most discerning consumers. The chips are now available in three generations. The “300s,” i.e. the A320, B350, and X370, are part of the first generation, which began in 2017.

AMD introduced the second generation in 2018, with the models B450 and X470. The third generation, which includes the current top model, the X570, debuted in 2019. It is AMD’s first self-developed Ryzen CPU chipset; the previous ones were made by ASMedia.

The new gold standard is B450.

The bulk of Ryzen consumers should choose for boards with the B450 chipset. As the better of the two mid-range versions, it has all of the essential characteristics for a solid business PC or a reasonably priced gaming PC. The product range is extensive, and there are several boards for space-saving PCs (Mini-ITX, ATX), as well as a fair price. If you don’t need AMD StoreMI, the somewhat less expensive B350 would suffice. However, keep in mind that the older 300 chipsets use more power. As a result, a pricing advantage at the moment of purchase might become a disadvantage over time.

The X570 with PCIe 4.0 stands out among the X chipsets. This enables the creation of ultra-high-performance computers. NVMe SSDs, which can transmit about 5 Gigabytes per second in reality, are now available; the maximum speed is 8 Gigabytes per second. The Radeon RX 5700 comes with an accompanying graphics card (GPU), allowing you to design a system entirely based on PCIe 4.0. However, appropriate boards are only 165 dollars (as of April 2020), and the rest of the components are likewise costly. For contrast, X470 boards start at 115 dollars, while X370 boards start at 65 dollars.

The owner may utilize PCIe 3.0 x16, two mechanical PCIe 2.0 x16 slots, and one PCIe 2.0 x1 connection all at once for expansion slots. Due to the limited number of FCH lanes, Gigabyte had to split the final three slots. The holes were filled by two M.2-M key interfaces, one of which works at 32 GBit/s through the CPU/APU and the other at 16 GBit/s via the chipset. In the storage section, six SATA 6 GBit/s ports have been installed.

Four USB 3.1 Gen1s, two USB 3.1 Gen2s, one Gigabit LAN (Intel I211-AT), and the typical audio connectors are all available on the I/O panel with pre-mounted panel. The DVI-D and HDMI 2.0 graphics outputs may be utilised if an APU is plugged into the socket. Internal headers may be used to add two more USB 3.1 Gen1 and four USB 2.0 connections. A nice onboard sound solution was implemented using the Realtek ALC1220 and some audio capacitors.

The high power consumption, both at idle and under load, is, on the other hand, a disadvantage. However, if no overclocking is used, a lower VCore may compensate. Some RGB LEDs have been put on and beneath the board, and the whole illumination may be optionally expanded using two RGB headers.


Finally, the price determines whether or not the Gigabyte B450 AORUS Pro is worthwhile. If WLAN is a concern, Gigabyte also provides an identical model with a WLAN-ac module. Aside from the high power consumption, the Gigabyte B450 AORUS Pro has shown to be a reliable motherboard.
