The difference between MediaTek's mt7688 and mt7628

MT7628andMT7688The two routing module chips are bothMediaTekDevelopment, MT7628K is a complete solution for entry-level routers, including integrated DRAM, L-shaped PCB, 5V/0.6A power supply and eCos software. MT7628A is for smart routing and IoT gateway applications, can be plugged into DRAM, and expands the support and loading of different applications based on Linux SDK and OpenWrt SDK. MT7688 can handle more complex or data-intensive smart home devices, such as IP projectors and home monitoring systems. Many users do not understand the difference between mt7688 and mt7628, and they can't tell which one is better, mt7628 or mt7688?
MT7628K/N/A is a 2x2 11n platform for N300/AC750/AC1200 routers and repeaters.
MediaTek MT7628 family is the new generation of 2T2R 802.11n WiFi AP / router (system on chip). MT7628 can improve RF performance, reduce power consumption, and optimize the overall bill of materials (BOM) cost, making it the most cost-effective 2x2 11n solution. The MT7628 family integrates 2T2R 802.11nWiFi transceiver, 580MHz MIPS? 24KEc? CPU, 5-port high-speed Ethernet port physical layer (Ethernet PHY), AES128/256 security engine, USB2.0 host, PCIe host, and multiple slow input and output (I/O) to connect different sensors. MT7628A can connect to the external dynamic random access memory (DRAM) of 11ac synchronous dual-band router. Router mode provides 5p FE switch, which is mainly designed for routing applications. On the other hand, IoT mode supports 1p FE and many slow input and output (I/O). Users can add an 802.11ac chipset to build an 802.11ac simultaneous dual-band IoT gateway. The MT7628K has 8MB of built-in memory and provides an eCos turnkey solution for small routers, repeaters, IoT bridges, storage and audio applications. The functions provided by the MT7628N are roughly the same as those of the MT7628A, the only difference is that the PCIe and IoT modes of the MT7628N are mainly designed for the N300 router.
MT7688A is a 1T1R 802.11 b/g/n wireless network platform designed for signal repeaters, storage, audio applications, and IoT gateways.
MediaTek MT7688 family chips integrate 1T1R 802.11 b/g/n wireless transmission functions, using MIPS?24KEc?/580MHz central processing unit (CPU), 5-port high-speed Ethernet switch or single-port ultra-high-speed Ethernet PHY, as well as USB 2.0 host controller, PCIe, SD-XC, I2S/PCM and a variety of slow I/O device interfaces. MT7688 has dual operating modes, of which MT7688K has built-in 8MB memory, which can provide industrial electronic turnkey mode for mini routers, signal repeaters, IoT gateways, storage, audio applications, etc. This chip can be expanded with a set of 802.11ac chipsets to establish an 802.11ac dual-band wireless IoT gateway.
MT7688A provides IoT device mode, which supports more peripheral interfaces: including eMMC, SD-XC, SPI slave, 3 UART ports, PWM and more GPIO. Various devices and bridges equipped with MT7688A have passed the Apple smart home platform HomeKit extension technology certification.

I believe that with the above knowledge about the difference between mt7688 and mt7628, the question of which one is better, mt7628 or mt7688, will be easily solved.
