FAQ about AMD Epyc, Ryzen and Zen 3 Processors

What is new with AMD Ryzen and Zen 3?

As AMD was intensifying its competitiveness vs Intel, AMD decided to go for an aggressive development cycle and use a 7nm process. With just under 20% more Instructions Per Cycle, it is a serious upgrade for most use cases, busines & consumer. The higher clock speeds help in particular for a set of use cases in the mainstream computing space.

What is Smart Access Memory and do I need it?

AMD Smart Access Memory is intended to optimize the use of AMD Ryzen processors to use the full capability of the graphics card memory. Within a traditional deployment, Windows will only let a particular amount of VRAM be used at any given time. AMD Smart Access Memory uses PCI Express in order to remove these limitations.

Will memory performance increase with AMD Ryzen / EPYC and Zen3?

With AMD showing us that this is the last series of processors that use DDR4, we know that AMD has taken some steps to optimize memory performance. Memory overclocking on this line of processors has become extensive. Fabric overclocking has become quite a feature among the use cases that require memory overclocking. While AMD has been slower and BIOS settings were not the cleanest upon initial release, 2021 releases have shown that this can now be done with ease.

Which Ryzen processor is best for Hosting Companies and Data Centers?

With the focus of power/performance ratios as well as power cost optimizations in a traditional deployment, AMD has used Zen 3 to attack the Data Center and hosting market in a way which it never had before. The improved Instructions Per Cycle and the 20-45% power reduction metrics at the TDP level make it an impressive and outstanding choice for hosting companies & data centers.

What will come after Zen 3 for AMD?

The rumors around Zen 4 are somewhat spare and fairly unreliable. Some of the implications suggest Zen 4 will have support for Quad Channel DDR5. With Zen 4 being years away if rumors to be relied on, we suggest all use cases take the added performance of the Zen 3 line. Given its relative performance to the competition and enhanced power efficiency benefits, we think it’s a great time to take up the Zen 3 line.
