AMD Extends AM5 Platform Support Through 2029AMD pledged to support its AM5 desktop motherboard platform through 2029, giving users a longer upgrade path without requiring a new motherboard.The company positioned the move as a value proposition for PC gamers and enthusiasts who want to upgrade processors over time while keeping existing hardware, the Verge reported on Monday.Alongside its platform commitment, AMD introduced refreshed versions of older processors.The company unveiled a “10th Anniversary” edition of the Ryzen 7 5800X3D for AM4 users and launched the Ryzen 7 7700X3D for the AM5 platform.By extending the life of proven gaming chips, AMD aims to attract both existing customers and users considering a transition to the AM5 ecosystem.NVIDIA Challenges AMD In PC Processor MarketHuang described the product as a reinvention of the personal computer, with AI assistants becoming the primary way users interact with their devices.AMD Technical AnalysisAdvanced Micro Devices stock traded lower by 3.40% in Monday’s premarket session. The move came as traders cut exposure to high-beta names, even as index futures stayed modestly higher.Nasdaq futures rose 0.10%, while S&P 500 futures gained 0.19%. That makes AMD’s weakness look more stock-specific than part of a broader market sell-off.AMD remains in a strong uptrend after a sharp multi-month rally. The stock is trading 12.7% above its 20-day SMA of $440.11 and 108.7% above its 200-day SMA of $237.58.The trend setup is still positive. AMD’s 20-day SMA is above its 50-day SMA, and the stock has stayed supported since a golden cross formed in July 2025.However, momentum looks stretched. AMD’s RSI is 76.08, after first moving into overbought territory in May. RSI readings above 70 often signal that a stock may be due for a pullback or sideways trading.AMD has gained 350.23% over the past 12 months. That keeps the longer-term backdrop constructive. Still, the stock’s wide gap above key moving averages may leave it vulnerable to sharper shakeouts.Traders will likely watch whether AMD can hold above its rising 20-day and 50-day moving average zones. A hold above those levels would help keep the broader uptrend intact.
