AMD Ryzen 7 5700U vs AMD Ryzen 7 4980U vs AMD Ryzen 7 4800H
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.
Long-term performance sustainability of a mobile CPU tends to depend heavily on cooling system performance as well as TDP settings of a laptop. That said, Ryzen 7 5700U is one of the fastest U-class CPUs of 2021. As such, a 5700U will outshine any U-class Intel CPU, beating certain H-class Intel processors such as the Intel Core i5-11400H in the process. AMD Zen 2 is a fairly mature architecture, and eight Zen 2 cores are a force to be reckoned with, even at a 15 W TDP.
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 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 15 W TDP that OEMs are free to change to anywhere between 10 W to 25 W. 4980U is a good fit for ultraportable laptops but is unlikely to play well with passive cooling solutions.
AMD Ryzen 7 4800H► remove from comparison
The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The CPU also has 8 MB of L3 cache and a Vega series integrated GPU. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads.
Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance. Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.
A 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s.
The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir processor family hub for more information on these CPUs.
Long-term performance sustainability of any mobile CPU tends to depend heavily on cooling system performance as well as TDP settings of a laptop. That said, the average 4800H in our database beats the Intel Core i7-10875H with ease, approaching the realm of Intel Core i9-10980HK. The Ryzen's single-core performance does not look quite as impressive though as it can trail behind Core i3-1005G1 (a dual-core Ice Lake part) in certain tests. This is not really important as most modern apps will gladly load as many cores as they can get access to.
Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The iGPU's underlying architecture is fairly old as of 2021, yet its 448 shaders will let you play many games of 2020 and 2021 as long as you stick to reasonable resolutions and presets. F1 2021 runs well at medium quality, 1080p resolution, to give you an example. A Vega 7 can be as fast as a GeForce GTX 1050 Max-Q, or as slow as an 80 EU Iris Xe; this depends on the benchmark as well as on cooling system performance and TDP settings of a laptop as mentioned above. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.
The Vega definitely supports UHD 2160p monitors at 60 Hz. This iGPU is capable of hardware decoding AVC, HEVC and VP9-encoded videos. There is no AV1 support here.
Ryzen 7 4800H has a default TDP of 45 W which can be changed to anywhere between 35 W and 54 W by an OEM. The chip is a good fit for gaming laptops as well as portable workstations, with high-performance cooling solution being pretty much a necessity. AMD Ryzen 7 4800HS is a 35 W edition of Ryzen 7 4800H designed for leaner, less power-hungry systems.
