MagyarApple M3 Max 14-Core vs Intel Celeron 5205U
Apple M3 Max 14-Core
► remove from comparison
The Apple M3 Max 14 core CPU is a system on a chip (SoC) from Apple for notebooks that was introduced towards the end of 2023. It integrates a new 14-core CPU with 10 performance cores with up to 4.06 GHz and 4 efficiency cores with 2.8 GHz. There is also a more powerful 16-core variant with 40 GPU cores.
Thanks to the higher clock rates and architectural improvements, the processor performance is also significantly better than the M2 Max in benchmarks and can keep up with the fastest mobile CPUs.
The M3 also integrates a new graphics card with dynamic caching, mesh shading and ray tracing acceleration via hardware. In the cheaper model, 30 of the chip's 40 cores are used and support up to 5 displays simultaneously (internal and 4 external).
GPU and CPU can jointly access the shared memory on the package (unified memory). This is available in 36 and 96 GB variants and offers 400 GB/s maximum bandwidth (512 bit bus).
The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (compared to 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now also supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded. Like its predecessor, the Max chip offers two video engines and can therefore encode and decode two streams simultaneously.
Unfortunately, the integrated WLAN only continues to support WiFi 6E (no WiFi 7), unlike the small M3 SoC thunderbolt 4 is also supported (max 40 Gbit/s).
The chip is manufactured in the current 3nm process (N3B) at TSMC and contains 92 billion transistors (+37% vs. Apple M2 Max).
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.
