EQUITY RESEARCH USA | Semiconductors Semiconductors 1Q21 CPU Share: AMD Gains 300bps in Servers + Links to Related Research Notebook ARMageddon 5-May-21: Cloud Instance Analysis - May 7, 2021 Mar'21: AMD Regaining / Datacenter Reaccelerating Key Takeaway 30-Apr-21: Semis on Fire: Q121 Mid- According to Mercury, in 1Q21, AMD gained 300bps and 150bps of CPU revenue share Earnings Season Takes QQ in dual servers and notebooks, respectively. On a YY basis, AMD gained 685bps of server revenue share. We expect AMD's server share gains exceed 150bps/qtr as it ramps 28-Apr-21: AMD Q121: Share Gains its 7nm Milan CPUs through 2021 and its 5nm Genoa CPUs in 2022. Separately, ARM Accelerate now accounts for 6% of notebooks. Reiterate Buy on AMD, and ARM plays MRVL and 16-Apr-21: Semis on Fire: Chipaggedon + NVDA. an NVDA A-Day Analogy Our Key Takes from the 1Q21 Share Analysis: 2-Feb-21: AMD 4Q20 Share Analysis: 1) AMD Server Share Gains Accelerated to 300bps in 1Q21, from an average of ~100bps/ Server Share Gains Continue qtr over the past four quarters to 11% on a revenue basis. We expect AMD share gains 26-Jan-21: Expect Continued Share Gains - to exceed 150bps a quarter for the next 4-to-8 qtrs. Reiterate Buy 2) Notebook ARMageddon: ARM is now 7% of total NB unit share, split 55/45 between 27-Aug-20: AMD+XLNX: A Match for the Apple MacBooks and Chromebooks. Edge 3) ARM in Servers: Mercury Research shows ARM servers at 0.6% share, but concedes INTC: A Butterfly Flaps Its Wings in 2005... it may be undercounting ARM servers. Our analysis suggests that ARM CPUs are now 19% of available instances at AWS. The 4th Tectonic Shift in Computing: To a Parallel Processing / IoT Model 4) Desktops: AMD lost 120 bps QQ on unit share but was flat QQ on rev share, suggesting it continues to move upmarket. In 1Q21, ARM makes up 0.6% share in desktops. Our Top Picks: We believe investors are underestimating the inflection of the ARM ecosystem in the computing market. Our top ARM plays are MRVL, NVDA, and AMD. For AMD, our 4- to 5-year EPS power is $7.40 assuming a 50% share and alternatively a 2- to 3-year EPS power of $4.90 assuming a 30% market share.

Within AWS, Graviton instances have increased to 19% of total CPU instances available as of Mar-21, up from 1% in the Jun-19Q and 18% in Feb-21. Graviton's share gains at AWS have come at the expense of INTC, which has seen its CPU instance availability decline to 64% of total in Mar-21 from 88% in Jun-19.
