OV7670 was released on August 15, 2005; OV2640 was released in the following year (2006).
Both sensors were initially designed for mobile applications.
Both sensors have build-in ISP and output YUV and RGB video format
What makes these two discontinued sensors more and more popular in recent years is their cost-effectiveness, successful integrations with MCUs, the growing trend of embedded systems, and the rise of machine learning and computer vision technologies.
OV7670 works right after the power is applied and no additional register settings are required，while OV2640 must do registers initialization to make it output any video.
OV2640 offers higher resolution and more importantly, it has an on-chip JPEG encoder, which offloads the processing power from low-end MCU and takes much less memory footprint on limited MCU internal RAM.
If VGA resolution at 30 fps is good enough for your project, OV7670 is usually a better choice because it’s way cheaper than the OV2640 camera.
