AMD Ryzen 3 4300U vs AMD Ryzen 5 3500U vs AMD Ryzen 5 4600HS
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).
AMD Ryzen 5 3500U► remove from comparison
The AMD Ryzen 5 3500U is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.1 GHz to 3.7 GHz with a Radeon RX Vega 8 iGPU with 8 CUs (512 Shaders) clocked at up to 1200 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. In Chromebooks, AMD calles the APU AMD Ryzen 5 3500C, but the specifications (and performance) are the same.
The Picasso SoC uses the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12 nm process allows for higher clocks at similar power consumption.
The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.
AMD states that the Picasso APUs are about 8% faster than the predecessors. Therefore, the Ryzen 5 3500U should be ahead the Ryzen 5 2500U (2 - 3.6 GHz) and nearly on par with the Ryzen 7 2700U (2.2 - 3.8 GHz). The performance in our tests depends a lot on the used TDP settings and cooling system. Looking at our Cinebench R15 loop you see a huge difference on the sustained performance, but not as high as for the Ryzen 7 3700U. The average Ryzen 5 3500U for example is even slightly faster than an average Ryzen 7 3700U in our tests (performance rating). Compared with Intel CPUs, the 3500U is on par with a Intel Core i5-8265U (Whiskey Lake Quad-Core 1.6 - 3.9 GHz).
AMD Ryzen 5 4600HS► remove from comparison
The AMD Ryzen 5 4600HS is a mobile SoC for big laptops based on the Renoir architecture. The 4600HS integrates six of the eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (12 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 similar named Ryzen 5 4600H, the 4600HS is the power efficient version with a TDP of 35 Watt (10 Watt less).
Due to the two deactivated cores and the slower Turbo clock speed, the Ryzen 5 4600HS should be significantly slower than the Ryzen 7 4800HS. The old top model Ryzen 7 3750H is still clearly slower due to the four Zen+ cores. Compared to the competition, the Intel Core i7-8850H (6-core Coffee Lake 2.6 - 4.3 GHz) should offer a similar performance.
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 35 Watt (default). Although the TDP is 10 Watt lower than the Ryzen 5 4600H, the chip is still intended for big and relatively heavy laptops.
