ASUS VivoBook 14 Family Explained
One reason buyers find the ASUS VivoBook 14 confusing is that ASUS uses the same VivoBook branding across multiple processor generations and hardware platforms. Models such as X1404VA, X1404V, and M1407KA share a similar design but target different users and budgets.
The X1404VA represents the traditional entry-level platform, typically paired with Intel's Core i3 or earlier Core i5 processors for everyday productivity. The X1404V refreshes the same chassis with Intel's newer Core 5-120U (Raptor Lake Refresh), providing more CPU cores, improved multitasking, and stronger Iris Xe graphics, but without a dedicated AI processor (NPU).
The M1407KA is a much larger platform upgrade rather than a simple refresh. It moves to AMD's Ryzen AI architecture, introducing an XDNA 2 Neural Processing Unit (NPU) capable of 50 TOPS, qualifying it as a Microsoft Copilot+ PC. It also adds DDR5 memory with expansion support, a taller 16:10 display, dual USB-C ports, HDMI 2.1, Wi-Fi 6, Bluetooth 5.3, and a Full HD IR webcam, making it the most feature-rich VivoBook 14 in this comparison.
ASUS follows this strategy to cover multiple price segments with a familiar product family. Instead of redesigning the laptop every year, the company updates the internal platform Intel for mainstream productivity and AMD Ryzen AI for next-generation AI computing allowing buyers to choose the level of performance and features that best fits their needs without changing the overall VivoBook experience.
