Intel Celeron 5205U vs AMD Ryzen 3 PRO 5450U
Intel Celeron 5205U
► remove from comparison
The Intel Celeron 5205U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Celeron 4205U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at only 1.9 GHz (no Turbo) and don't support SMT / HyperThreading (so only 2 threads). More information on Comet Lake and all the models and articles on it can be found here.
The integrated graphics adapter is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 4205U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster and costlier Core i3/i5/i7 processors).
Performance
While we have not tested a single system powered by the 5205U as of August 2023, it's safe to expect the chip to be about half as fast as the Core i3-10110U (Comet Lake, 2 cores, 4 threads, up to 4.1 GHz). Which is nothing to write home about, really, as of mid 2022.
Power consumption
This Celeron has a default TDP, also known as the long-term power limit, of 15 W. Intel officialy allows laptop manufacturers to reduce that value somewhat, 12.5 W being the lower limit, resulting in lower clock speeds and lower performance. Unlike most Comet Lake family processors, Celeron 5205U is fairly likely to actually stick to that limitation as its cores are not Boost-enabled.
Last but not the least, this CPU is manufactured on an old, as of late 2022, 14 nm Intel process making for subpar energy efficiency.
AMD Ryzen 3 PRO 5450U
► remove from comparison
The AMD Ryzen 3 PRO 5450U is a processor for thin and light laptops based on the Cezanne generation. The R3 5450U integrates four of the eight cores based on the Zen 3 microarchitecture and is the slowest U-series processor of the Cezanne generation at launch. The cores are clocked at 2.6 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (8 threads). The chip is manufactured in the modern 7 nm process at TSMC.
The PRO CPUs offer additional management and security features. The 5450U is otherwise identical to the Ryzen 3 5400U.
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.
Performance
While we have not tested a single system built around the 5450U as of August 2023, we are fairly confident the chip is a little faster than the Ryzen 3 5300U and its four Zen 2 cores running at clock speeds similar to what the 5450U has. Naturally, your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.
In addition to the four CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics card with 6 CUs and up to 1600 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache (same as the old 4800U) can be found on the chip.
The TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor (most chips are configured higher than 15 Watt). That means the chip is intended for thin and light laptops (but with fans).
