The AMD Ryzen 5 4600U is a low-power mobile processor intended for thin and light laptops launched in January 2020. The 4600U comes with 6 integrated cores that simultaneously process 12 threads at a time, because of SMT support. The cores are clocked at a base frequency of 2.1GHz with a turbo boost frequency of 4.0GHz and an integrated Radeon Vega 6 graphics that has a maximum clock speed of up to 1500MHz; all operating at a default TDP of 15W.
This chip is manufactured using the modern 7nm TSMC’s FinFET technology which greatly improves its performance and power efficiency per Watt. The nominal TDP of this mobile processor, as mentioned above, is rated at 15W which means you can easily use the chip in thin notebooks or Ultrabooks up to 14 inches. 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.
Additionally, the Ryzen 5 4600U is based on the Zen 2 architecture, which is the successor of Zen, featuring a doubled L2 (4MB) and L3 cache (8MB) memory per core with a higher cache op hit rate, a doubled prefetch for branch prediction accuracy, clock and data gating improvements, low-power design methodology. Summarily, the Zen 2 architecture improves the overall performance and efficiency of the Ryzen 5 4600U, that is: the instructions per unit of energy is approximately doubled.
The chip’s Renoir design and build also supports PCIe version 3.0 which is used to communicate between the chipset and storage devices or other components. Furthermore, it offers support for 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.
The performance of Ryzen 5 4600U compared to Ryzen 5 4500U is relatively higher, although both are designed specifically to run the latest operating systems and applications. Both processors actually share similar features from the number of cores, TDP ratings to integrated graphics operating at the same GPU frequencies (1.5GHz).
The 4600U comes with a base frequency of 2.1GHz (200MHz lower than that of 4500U) and both have the same turbo frequency up to 4.0GHz. However, 4600U beats 4500U in single-core and multi-core performance tests because it supports simultaneous multithreading technology; processing up to 12 threads unlike 4500U which processes 6 threads only. With regards to gaming performance, both CPUs meet all the minimum requirements of all games with slight differences in specific gaming features.
