AMD Ryzen 7 5700U vs AMD Ryzen 5 4600U
AMD Ryzen 7 5700U► remove from comparison
The AMD Ryzen 7 5700U is an APU of the Lucienne product family designed for leaner laptops. The Ryzen features eight Zen 2 cores clocked at 1.8 GHz (base clock speed) to 4.3 GHz (Boost) as well as a Vega 8 iGPU. Thread-doubling SMT tech is enabled in this CPU for up to 16 concurrent processing threads.
In spite of what its name may suggest, Ryzen 7 5700U is not a Zen 3 part, meaning this is a Ryzen 4000 series mobile processor in disguise. Nevertheless, the CPU is manufactured on the modern 7 nm TSMC process and its performance as well as energy efficiency figures are very strong compared to what Intel currently has to offer in this segment.
The Ryzen 7 features 8 MB of Level 3 cache. Its built-in memory controller is designed to work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. Unlike the desktop Ryzen 5000 processors, Ryzen 7 5700U does not support PCI-Express 4.0, meaning those speedy NVMe SSDs will be limited to read/write rates of 3.9 GB/s.
The Ryzen gets soldered directly to the motherboard (FP6 socket) and is thus not user-replaceable.
Ryzen 7 5700U is one of the fastest U-class CPUs of 2021. As such, it trades blows with Intel Core i7-1260P and AMD Ryzen 5 4600H in multi-thread benchmarks, the latter being a much more power-hungry part. The Ryzen 7 will meet the needs of power users without breaking a sweat.
In addition to its eight CPU cores, Ryzen 7 5700U features the Radeon RX Vega series graphics adapter with 8 CUs (= 512 shaders) running at up to 1,900 MHz. This iGPU trails behind the 96 EU Intel Iris Xe Graphics G7 in synthetic benchmarks, yet its real-world performance is good enough for many games released in 2020 and 2021 at reasonable resolutions (up to Full HD 1080p) and low to medium quality. As the Vega has no VRAM of its own, it is paramount that fast system RAM is used.
The graphics adapter definitely supports UHD 2160p monitors at 60 Hz, and will gladly HW-decode AVC, HEVC and VP9-encoded videos. There is no AV1 support here though.
This Ryzen is manufactured on the 7 nm TSMC process for a very decent energy efficiency. Ryzen 7 5700U has a default TDP of 15 W that can be changed to anywhere between 10 W and 25 W by and OEM. The chip won't look out of place in super-slim laptops of all sizes (with an active cooling solution, if possible) as well as mini-PCs and portable gaming consoles and other fancy things.
AMD Ryzen 5 4600U► remove from comparison
The AMD Ryzen 5 4600U is a processor for thin and light laptops based on the Renoir architecture. The 4600U integrates six cores based on the Zen 2 microarchitecture. They are clocked at 2.1 (guaranteed base clock) to 4 GHz (Turbo) with SMT / Hyperthreading support (12 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips.
With two less cores, the Ryzen 5 4600U is clearly slower than the Ryzen 7 4700U and 4800U in multi threaded workloads. However, it should still beat the fastest 15 Watt Ice Lake Intel Core i7-1065G7 (4 cores, 3.9 GHz). Thanks to the 4 GHz Boost clock, the single core performance should be similar. Therefore, the Ryzen 5 4600U is a very fast 15 Watt CPU and clearly faster than the old Ryzen 7 3700U.
In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.
The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor. That means the chip is intended for thin and light laptops (but with fans).
