The release of Mobile Ryzen 4000, like most events, affected the coronavirus pandemic, which delayed not only the availability as such, but also the first samples to be tested, so the release in mid-March was only formal – no tests, no availability. This has now been corrected by the NDA review, so a number of websites around the world have brought tests for the new Ryzen 7 and Ryzen 9, whose specifications can be found in the table below:

There is no point in trying to summarize and generalize all the measured results – each product is unique and in laptops even more than in the desktop, the performance besides the processor is very dependent on its cooling. So we will just list a few points of interest:
|CPU||CINEBENCH R20||BLENDER||MAX POWER DRAW|
|Core i9-9980HK||3 239||20:55||80 W|
|Ryzen 7 4800HS||3 933||20:42||54 W|
A simple table from the HardwareTimes website compares the Core i9-9980HK with the Ryzen 7 4800HS, which is not the most powerful product in the series, but the fourth in performance. Nevertheless, it has no problem to overcome the current top model of Intel, which is half the consumption. Intel's renowned mobile processors disappear forever, with the Core ix 9000H series, Intel had to go well beyond TDP, and the expected Core ix 10000H series would be extremely extreme.
As it is TDP for AMD Renoir? To some extent it depends on the settings of a particular product (laptop), so as an example we will take Asus Zephyrus G14 with 35W Ryzen with ComputerBase measurements:
|Silent (socket)||25 W||50 W||2.95 GHz||31-38 dB|
|Silent (battery)||15 W||20 W||2.40 GHz||31-33 dB|
|standard (socket)||35 W||65 W||3,25 GHz||31-44 dB|
|standard (battery)||20 W||25 W||2.90 GHz||31-37 dB|
|turbo (socket)||35 W||65 W||3,25 GHz||37-45 dB|
In the standard mode, the APU runs with a TDP of 35 watts, which means it consumes 35 watts in a long-term load and can only reach a maximum of 65 watts at a time. In the HardwareTimes test, however, it did not reach more than 54 watts. When running on battery power, TDP is reduced to 20 watts and peak one-time consumption to 25 watts. Quiet mode sets the TDP to 25 watts (with a maximum of 50 watts) and while running on the battery to 15 watts (a 20 watts maximum). Turbo mode does not increase the limits but the radiator speed, so higher heating or higher ambient temperatures will not limit performance. However, the minimum noise level increased by 6 dB. These figures indicate that 80 watts, such as the Core i9-9980HK, Ryzen 7 4800HS cannot even take theoretically.
What about low power consumption and battery life?
The Hardware Canucks editors tested the 35W Ryzen 9 4900HS, the most powerful 35W model, and found that the Asus RoG Zephyrus G14 lasted nine and a half hours in a web-simulating test. This is the result, which is more common for products optimized for minimum consumption and equipped with 10-15W chips.
The chapter itself is an integrated GPU. AMD u Renoir chose the path of further development of architecture Vega, which in the case of APU Renoir got to a similar level as the upcoming computational GPU Arcturus. Although the number of computing units has decreased, real gaming performance has increased incredibly – by about 2/3, although data throughput (DDR4-2400 -> DDR4-3200) has increased by only 1/2. There does not seem to be any new memory constraint Vegu in flight:
Although AMD has repeatedly outperformed Intel in the desktop world, in the mobile world, Intel has managed to hold its teeth-nails. Se Zen 2 but it is also over. Although we can expect with the release of the tenth series Lake Comet-H Intel will be able to regain some of the primacy, but given the current 80W power consumption of 45W models, it will be even more at the expense of power consumption, battery life and waste heat. Intel's offerings are now very compromise – the user can choose between processor power (at the expense of power) with 14nm models and graphics power (but at the expense of processor power) with quad-core 10nm models. AMD with APU Renoir managed to deliver cutting-edge processor and graphics performance while still reducing power consumption.
