AMD Ryzen 9 4900HS vs Intel Core i7-9700K
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.
Intel Core i7-9700K
► remove from comparison
The Intel Core i7-9700K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3.6 - 4.9 GHz and it needs a new Z390 based mainboard.
Thanks to the two additional cores, the performance in multi-threaded applications is even better than the old Core i8-8700K with 6 cores and Hyperthreading. As a high end desktop CPU, the i9-9700K is suited even for very demanding applications and perfect for 3D gaming.
The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).
Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to 200 Watt and higher.
