Investors are gearing up for Nvidia's (NASDAQ: NVDA) fiscal 2027 second-quarter earnings, which will be released after the market closes on Aug. 26. Nvidia's fiscal year begins in late January or sometimes early February, so it is fairly close to the calendar year. In fiscal 2026, most of which occurs in calendar year 2025, Nvidia's data center division generated nearly $194 billion in revenue. According to Visible Alpha, Wall Street consensus estimates expect data center revenue to be nearly $368 billion in fiscal 2027 and nearly $531 billion in fiscal 2028. While the focus will and should be on the GPU business, investors should not overlook Nvidia's central processing unit (CPU) business, which is fairly new.
