AMD’s CEO Lisa Su shipped the virtual CES 2021 keynote this 12 months. The business made a number of announcements in the course of the occasion, such as the start of its Ryzen 5000 cell processors and a preview of what we can count on when third-technology Epyc, codenamed Milan, debuts afterwards this 12 months.

The Ryzen 5000 cell family members will introduce some targeted advancements to specific SKUs, but it is a bit of a combined bag, relying on which segments you are intrigued in. Consumers looking for better electricity, better overall performance laptop chips in the 35-45W vary could be happier than these in the slim-and-gentle markets.

A Bifurcated Refresh

There is a vary of new chips in the 35W-45W TDP segment, branded as the “HX”, “HS”, and “H” households. The new HX CPUs are for overclocking and allow for a better TDP than typical — these are detailed as “45W+” chips.

HS CPUs now have the exact turbo clock as H-family members CPUs, but a decreased base clock and a decreased TDP over-all. These chips are rated for 35W as an alternative of 45W. All of these CPUs are primarily based on the Zen 3 architecture, which indicates they should really supply the 1.19x IPC improvement AMD demonstrated with the Ryzen 5000 series on the desktop, as perfectly as attributes like the expanded L3 cache.

The “U” family members, even so, incorporates far more rebadged Ryzen 4000 areas than it does Ryzen 5000 series chips. You can tell which is which due to the fact the Zen 2 chips have significantly less than 50 % the cache.

Only the Ryzen 7 5800U and Ryzen 5 5600U are primarily based on Zen 3 the 5700U, 5500U, and 5300U are all Zen 2-primarily based CPUs. According to AMD’s slides, the 5600U is quicker in single-threaded code than the 5700U but modestly slower in multi-threaded code.

There doesn’t look to be a refresh on the built-in GPU aspect of issues, although AMD could have tweaked clocks or effectiveness in a method that enhances overall performance. The company’s overall performance promises exhibit little uplifts for even the Zen 2-primarily based areas in CPU workloads, likely thanks to approach node tweaks and other very low-degree optimizations. All of AMD’s disclosures concentrated on the CPU aspect of the equation, which implies the GPU isn’t modifying significantly.

This doesn’t mean the Ryzen Cell 5000 family members won’t raise battery lifestyle and over-all system effectiveness — AMD promises up to 17.5 hours typical usage and up to 21 hours of movie playback for the Ryzen 7 5800U — but it indicates these advancements will come on the CPU aspect of the equation.

And a Bit About Epyc

AMD also briefly demoed its approaching third-technology Epyc CPUs, codenamed Milan. We do not count on any extraordinary main count expansions this cycle, and the new chips should really drop in as replacements for the former technology, as far as system assist is anxious. The business did not have significantly to exhibit — just the effects of a single benchmark boasting a twin-socket Epyc geared up with two Milan 32-main CPUs was 46 p.c quicker than an equivalent system outfitted with Xeon Gold 6258R 28-main chips. In single-socket overall performance, AMD claimed a 68 p.c variance with the exact Xeon system when operating in a single socket.

AMD’s Milan and Intel’s Ice Lake Xeons will slug it out against just about every other afterwards this 12 months, but without the need of far more details, we simply cannot say significantly about AMD’s promises. All round, it is excellent to see Zen 3 come to cell, but the crystal clear concentration this 12 months is on expanding AMD’s skill to compete for better-conclude gaming notebooks in the 35-45W+ TDP vary, as opposed to concentrating on the ultra-very low-electricity marketplace. Ideally, we’ll see a far more total refresh of the full system following 12 months, with the presumed arrival of Zen 4.
