AMD Ryzen 7 4700U Mobile Processors with Radeon Graphics

The AMD Ryzen 7 4700U is a 64-bit octa-core mobile processor for thin laptops. Its cores are based on the Renoir architecture with only 8 threads; there’s no support for simultaneous multithreading (SMT). All its eight cores operate at a base clock speed of 2.0GHz that can turbo boost up to 4.1GHz. With eight cores in total, the processor is able to carry out more advanced tasks such as handling high-resolution videos and graphic-heavy games without draining the battery, making the devices capable and efficient. Furthermore, this octa-core processor allows these thin and light laptop devices to have shorter load times.

This chip is manufactured using the modern 7nm TSMC’s FinFET technology which greatly improves its performance and power efficiency per Watt. The TDP of this mobile processor is rated at 15W which means you can easily use the chip in thin notebooks up to 14 inches diagonally. However, this nominal TDP can be configured as low as 10W and as high as 25W, especially if the thin laptop device with an efficient cooling system.

The processor features integrated Radeon Vega 7 graphics that can run up to 1600MHz. Additionally, the Ryzen 7 4700U is based on the Zen 2 microarchitecture, which is the successor of Zen, and features a doubled L2 (4MB) and L3 cache (8MB) amount per core and a doubled prefetch for branch prediction. The microarchitecture also supports PCIe version 3.0 which is used to communicate between the chipset and storage devices or other components. The chip also supports a dual DDR4 memory channel that operates up to 3200MHz as well as an LPDDR4 memory controller that runs up to 4266MHz RAM thus saving on power consumption for laptops.

In terms of performance, Ryzen 7 4700U (8×2.0GHz) is 26.98% faster than the Ryzen 5 5500U (6×2.1GHz). The 7 4700U is a 0.1GHz higher turbo boost than the 5 5500U and scores 0.43% higher than 5500U in single-core performance according to Cinebench R20. When compared to Ryzen 7 4800U, it is 4% slower because it doesn’t support SMT and it has a lower 0.1GHz turbo clock speed.

Note: This generation also supports AMD’s Precision Boost 2 technology which allows better tracking of performance states of individual cores while driving frequency up with AVFS (automatic voltage frequency scaling).
