AMD Ryzen 9 5980HX vs AMD Ryzen 5 4600U
AMD Ryzen 9 5980HX
► remove from comparisonThe AMD Ryzen 9 5980HX (in leaks also known as R9 5980H is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5980HX integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.8 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in the modern 7 nm process at TSMC. The "X" in the name indicates the overclocking capabilities of the CPU.
The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.
With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 9 5980HX should be clearly faster than the lower clocked Ryzen 9 4900H.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics card with 8 CUs and up to 2100 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache can be found on the chip.
Power consumption
This Ryzen 9 series chip has a default TDP, also known as the long-term power limit, of 45 W. Laptop makers are free to change that value to anything between 35 W and 54 W, with clock speeds and performance changing accordingly as a result. Either way, a powerful cooling solution is a must for a CPU like this.
The R9 5980HX is built with TSMC's 7 nm process for higher than average, as of late 2022, energy efficiency.
AMD Ryzen 5 4600U
► remove from comparisonThe AMD Ryzen 5 4600U is a processor for thin and light laptops based on the Renoir architecture. The 4600U integrates six cores based on the Zen 2 microarchitecture. They are clocked at 2.1 (guaranteed base clock) to 4 GHz (Turbo) with SMT / Hyperthreading support (12 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.
With two less cores, the Ryzen 5 4600U is clearly slower than the Ryzen 7 4700U and 4800U in multi threaded workloads. However, it should still beat the fastest 15 Watt Ice Lake Intel Core i7-1065G7 (4 cores, 3.9 GHz). Thanks to the 4 GHz Boost clock, the single core performance should be similar. Therefore, the Ryzen 5 4600U is a very fast 15 Watt CPU and clearly faster than the old Ryzen 7 3700U.
In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and up to 1500 MHz. 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 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).
