On forward P/E, Broadcom Inc. is actually cheaper at 36. 5x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Broadcom Inc. wins at 0. 73x versus Advanced Micro Devices, Inc. 's 11. 55x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

For long-horizon retirement investors, Marvell Technology, Inc.

(MRVL) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (+1581% 10Y return). Advanced Micro Devices, Inc. (AMD) carries a higher beta of 2. 30 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (MRVL: +1581%, AMD: +110. 9%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Technology sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: AAOI is a mid-cap high-growth stock; AVGO is a mega-cap high-growth stock; MRVL is a mid-cap high-growth stock; INTC is a large-cap quality compounder stock; AMD is a large-cap high-growth stock.
