AMD Ryzen 3000 processor gave an incredible boost to the company last year. Now AMD is intensifying the competition with its latest Ryzen 4000 series 8-core Mobile Processors codenamed “Renoir”. AMD is now stepping up their game against its rival Intel’s desktop and laptop processors.
AMD’s Ryzen 4000 series Mobile Processor codenamed “Veermeer” is expected to launch later in 2020
With AMD Ryzen 4000 series CPU and Nvidia’s Geforce GPU, this year is going to be a benchmark year for AMD. As many of the biggest games are expected to release latter half of this year. Ryzen 4000 is powered with AMD’s Zen 3 architecture, much more than its powerful and critically successful Zen 2 architecture unveiled last year.
As per AMD, this year’s Zen 3 architecture will be much more than a incremental upgrade from last years Zen 2. AMD’s latest silicon architecture is completely focused on 3 major features including higher efficiency, higher clock speeds and higher IPC agains.

The Zen 3 architecture is based on 7nm+ process technology and AMD has already confirmed that the company have already completed the design of the chip is expected to unveil in the Computex 2020 event in Taiwan. The event was pushed to September and later cancelled due to the COVID-19 pandemic situation.
The US based chipmaker initially released its first Ryzen 4000 series in CES 2020 early this year. where they showcased their new generation Mobile Accelarated Processing Units (APU) based on 7nm Renoir micro architecture with Zen 2 cores from its predecessor paired with their Vega graphics cores. The most attracted two processors from the line up were Ryzen 9 4900H and 4900HS CPU which will be drawn to the gamers. Both the chipsets are designed to take on Intel’s core-i9 processors which is considered as the top of the line in Mobile Processors.
In last few months many brands like Lenovo, Asus, HP and Dell have released their laptops with its low to high end chipsets from the Ryzen lineup. Lenovo Yoga Slim 7, Asus ROG Zephyrus 14, Dell G5 SE and HP Envy x360 series to name a few from the lineup.
Architecture
Ryzen 4000 series will use a combination of 2 architectures in the series. It will leverage the Zen 2 architecture in a different manner like the Ryzen 3000 series using the chiplet design. CPU cores are portioned into miniature chiplets and paired with a larger I/O die, the Ryzen 4000 Zen 2 mobile CPUs are built using a more traditional single monolithic die. Also it will be less noticeable in Mobile processors, hence it opted to integrate more elements — like LPDDR4X and low power audio into this monolithic dies design.

Ryzen 4000 series Zen+ design will be less power hungry since the I/O die won’t be present and require its own power also cache memory will be also reduced. Also the new design has reduced the process node size from 12nm to 7nm and other several architecture level of efficiency.
The 8-cores from the mobile processors are split into two CCX units with reduced L3 cache memory to 4MB per CCX from its predecessors 8MB cache from desktop processors. Also, AMD claims that with the 7nm design, the laptops will be greatly benefited from faster boot time, great battery life, smooth application performance and the latency has been lowered.
Performance
AMD’s Ryzen 4000 Mobile Processors are expected to deliver a major uplift in performance from its predecessor Ryzen 3000. Zen 2 design in 3000 series has delivered improvements of 15-20% in a single core threaded tasks and 25-30% in multi-threaded scenarios. AMD claims that compared to Intel, Ryzen 4000 can deliver much greater stability and consistency in performance as its mobile chip delivers two fold performance per watt.
In early test results released by AMD, the Ryzen chip on a Lenovo Yoga Slim 7 bested a comparable Intel Core i7-1065G7 system in web browsing and graphics activity, with battery life being comparable. In idle time, however, AMD’s system still loses by 7.5 hours when compared to Intel’s connected standby. We believe that AMD is still working on the optimization on battery improvements. A report from Notebook Check suggests that an unannounced and potentially shelved Lenovo Legion 5 gaming laptop could have double the battery life of a Legion 5 powered with Intel’s Comet Lake-H CPU.

AMD Ryzen 4000 U-Series Mobile Processors provide incredible responsiveness and portability, delivering disruptive performance for ultrathin laptops with a configurable 15W TDP. The 4800U provides up to 4% greater single thread performance and up to 90% faster multi-threaded performance and up to 18% faster graphics performance compared to the competition according to AMD. Strong multi-threaded performance up to 46% makes Ryzen laptops powerful mobile workstations.
With multithreaded performance, the 8-core, 16-threaded Ryzen 4800H design will give content creators serious power over laptops with a quad-core design.

Pricing and Availability
There was a earlier rumour that AMD Ryzen desktop processors release have been till 2021 due to lack of competition from its major competitior Intel Corporation. However, AMD has denied the rumours and clarified on its products roadmap and the Zen 3 is scheduled for a launch in 2020.
Since the chiplet architecture has been a huge commercial success for AMD and Zen 2 has proven its capability. We don’t expect any major price difference from the current pricing strategy from the AMD. As their products are currently winning over its rival Intel’s products and priced for its performance being offered.
However, we expect a price bump if the new SKU’s are adding more cores than the Ryzen 7 and Ryzen 9 processors as this will trigger higher demand for the product.
