AMD Ryzen 5 7530U vs AMD Ryzen 7 4980U

AMD Ryzen 5 7530U

The AMD Ryzen 5 7530U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers 200 MHz higher boost clock for the CPU cores compared to the old Ryzen 5 5625U (but a slower base clock speed). The R5 7530U integrates six of the eight cores based on the Zen 3 microarchitecture. The cores are clocked at 2 (guaranteed base clock) to 4.5 GHz (single core boost) and support SMT for a total of 12 threads. The chip is manufactured in 7 nm at TSMC.

Performance

The average 7530U in our database is in the same league as the Ryzen 5 5625U, Ryzen 7 4800U, Ryzen 7 PRO 5850U, Core i5-1335U, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 37 W, the VivoBook 15X OLED M3504YA is among the fastest laptops built around the 7530U that we know of. It can be roughly 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 7 (now only called Radeon Graphics) integrated graphics card with 7 CUs at up to 2 GHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Power consumption

This Ryzen has a default TDP of 15 W (also known as the Power Limit 1).

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

The 4980U is the fastest U-class Ryzen 4000 series chip. As such, its clock speeds are 200 MHz higher (both the base one and Boost one) than what the Ryzen 7 4800U has.

It is thus hardly surprising that the average 4980U in our database is in the same league as the Ryzen 7 5800U and also the Core i7-1260P, as far as multi-thread benchmark scores are concerned.

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 default TDP, also known as the long-term power limit, of 15 W; much like it is with other U-class Ryzen 4000 chips, AMD is fine with laptop makers (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, as of mid 2022, energy efficiency.
