As of mid 2022, the Ryzen is fast enough for nearly all apps and games you could possibly throw at it, and that will continue to be the case for at least a year and a half more. The average 4800HS in our database is an impressively fast CPU that isn't afraid of picking fights with Intel Core i9-10980HK and Core i7-11850H, as far as multi-thread performance is concerned. See our hub page on the Renoir Processors for more information. Furthermore, 8 MB of 元 cache can be found on the chip. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics adapter with 7 CUs at up to 1,600 MHz. The 4800HS is the 35 Watt version (-10 Watt) of the Ryzen 7 4800H. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. They are clocked at 2.9 (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT for a total of 16 threads. The 4800HS integrates all eight cores based on the Zen 2 microarchitecture. If the cooling system is insufficient, our the environment doesn't allow sufficient heat transfer, then temperatures will not drop.The AMD Ryzen 7 4800HS is a mobile SoC for big laptops based on the Renoir architecture.
Throttling the CPU just gives whatever cooling systems are in place a better chance at actually being able to remove the amount of heat being generated in a timely enough manner to prevent buildup and allow temperatures to eventually decrease. Assuming there's sufficient cooling for the heat being produced, or more appropriately there's enough airflow to move the heat away from the system, it will eventually start to cool. If not, temperatures will continue to rise unabated.
That means there's still heat being introduced into the system that needs to be removed in some way. It's still not producing a zero amount of heat (unless it completely shuts down), just less. Whatever temperature is set as some maximum will be the point where the CPU starts to dial back on its power budget/do less work in order to produce less heat. A heat source sitting out in the middle of the Sahara desert will take much longer to cool than one placed in a deep freeze. That process takes time, dictated by the steepness of the gradient. There's a lot of science involved here, but there's essentially a gradient and heat moves from areas of high temperature to areas of lower temperature.
Even in the best case scenario, temperature won't just drop immediately. I am just simply using Ryzen controller to limit the CPU temperature to 85 and its not working but i saw it on YouTube videos! People do that and their temperatures are at 80 85 90 whatever they set their limit to and the CPU clock speed or TDP automatically lowers according to the set temp limit!įirst, never trust anything you see on YouTube.
