AMD Ryzen 9 4900HS vs AMD Ryzen 7 4980U vs AMD Ryzen 7 4800HS
AMD Ryzen 9 4900HS► remove from comparison
The AMD Ryzen 9 4900HS is a mobile SoC for big laptops based on the Renoir architecture. The 4900HS integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4.3 GHz (Turbo) and support SMT / Hyperthreading (16 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
According to our information, the Ryzen 9 4900HS is only slightly faster than the Ryzen 7 4800HS. The CPU is clocked 100 MHz (base and boost) higher, but the gains greatly depend on the cooling and TDP settings. Compared to Intel chips, the i9-9980HK top model should be comparable. That means the Ryzen 9 4900HS should be able to handle all demanding tasks and gaming. Compared to the similar named 45W-version, the Ryzen 9 4900H, the 4900HS is differs in 100 MHz boost and 300 MHz base clock.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with most likely 7 CUs. 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 35 Watt (default). That means the chip is intended for big and relatively heavy laptops. The Ryzen 7 4900HS is the 35 Watt version of the R9 4900H with a 10 Watt lower TDP.
AMD Ryzen 7 4980U► remove from comparison
The AMD Ryzen 7 4980U is a Renoir family processor designed for certain Microsoft Surface systems. 4980U has eight Zen 2 cores clocked at 2.0 GHz (base clock speed) to 4.4 GHz (Boost) with thread-doubling SMT tech enabled for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to that AMD promises a 2x improvement in performance-per-Watt over Ryzen 3000 series mobile CPUs.
The Zen 2 microarchitecture has brought a sizeable per-thread performance boost compared to the outgoing Zen+ parts. Renoir product family is also the first to introduce 8-core ULV processors to laptop market, keeping power consumption within reasonable limits. This AMD processor family is very impressive from most perspectives. One of the disatvantages to keep in mind is the lack of PCI-Express 4 support, meaning these blazing-fast NVMe SSDs will be limited to 3.9 GB/s tops.
Ryzen 7 4980U is designed to work with quad-channel LPDDR4 memory at up to 4,267 MHz. 8 MB of Level 3 are present in this chip. The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir hub page for more information on the product family.
4980U is the fastest ULV Ryzen 4000 series model. As such, its clock speeds are 200 MHz higher (both the base and Boost) compared to the older Ryzen 7 4800U. We fully expect the new Zen 3 based Ryzen 7 5800U to be even faster thanks to the new architecture. In the meantime, 4980U proves to be nearly as fast as an i7-10870H in multi-core benchmarks while bending the knee to older Intel CPUs, such as the i5-8300H, when under single-thread load.
In addition to its eight CPU cores, the Ryzen 7 also features the Radeon RX Vega 8 graphics adapter with 8 CUs (= 512 shaders) at up to 1,950 MHz. This iGPU is compatible with FreeSync and DirectX 12 and is able to HW-decode AVC, HEVC, VP9-encoded videos (no AV1 support here). Vega 8 is capable of outputting UHD 2160p60 video signal to several monitors and, similar to Intel's Iris Xe (80 EUs), is good enough for a bit of light gaming on the go, provided one is content with sub-1080p resolutions and low/medium quailty presets.
The APU has a default TDP, also known as the long-term power limit, of 15 W; much like with other Ryzen 4000U processors, AMD is fine with laptop manufacturers (Microsoft, in this case) changing that value to anything between 10 W and 25 W. The 7 nm TSMC process this Ryzen 7 is built with makes for above average energy efficiency. All in all, Ryzen 7 4980U is not just powerful; it's also anything but a power hog.
AMD Ryzen 7 4800HS► remove from comparison
The AMD Ryzen 7 4800HS is a mobile SoC for big laptops based on the Renoir architecture. The 4800HS integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 2.9 (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT for a total of 16 threads. 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. The 4800HS is the 35 Watt version (-10 Watt) of the Ryzen 7 4800H.
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 dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB of L3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.
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. 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.
This Ryzen 7 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are allowed to change to anything between 35 W and 54 W with clock speeds and performance changing correspondingly. The CPU is built with TSMC's 7 nm process for very decent energy efficiency.
