AMD Ryzen 7 4980U vs AMD Ryzen 3 4300U

AMD Ryzen 7 4980U

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.

Architecture

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.

Performance

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.

Graphics

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.

Power Consumption

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 3 4300U

► remove from comparison

The AMD Ryzen 3 4300U is a processor for thin and light laptops based on the Renoir architecture. The 4500U integrates four cores based on the Zen 2 microarchitecture (quad core CPU). They are clocked at 2.7 (guaranteed base clock) to 3.7 GHz (Turbo) without SMT / Hyperthreading support (4 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. Compared to the faster Ryzen 5 4000 CPUs (e.g., Ryzen 5 4600U), the Ryzen 3 only offers 4 cores and lower Turbo clock speeds.

Thanks to the new Zen 2 cores, the Ryzen 3 4300U should offer a similar performance as the Ryzen 5 3500U. For an lower mid-range CPU, the performance is quite good and sufficient for most demanding tasks.

In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 5 integrated graphics card with 5 CUs and up to 1400 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB of 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 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor. That means the chip is intended for thin and light laptops (but with fans).
