The Apple M2 is a System on a Chip (SoC) from Apple that is found in the late 2022 MacBook Air and, MacBook Pro 13. It offers 8 cores divided in four performance cores and four power-efficiency cores. The big cores offer 192 KB instruction cache, 128 KB data cache, and 16 MB shared L2 cache (up from 12 MB). The four efficiency cores are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. The efficiency cores (E cluster) clock with up to 2,4 GHz, the performance cores (P cluster) with up to 3,5 GHz and therefore higher than the M1 cores. The architecture should be similar to the A15 (iPhone 13) with Avalanche and Blizzard cores.
The chip features a unified memory architecture for the CPU and GPU cores and supports up to 24 GB LPDDR5-6400 for a bandwidth of up to 100GB/s.
According to Apple, the M2 offers a 18% higher CPU performance at the same power consumption level compared to the Apple M1. In our tests, the MacBook Pro 13 with active cooling was able to reach the 18% in Geekbench Multi. In other benchmarks we measured 12 to 15% gains compared to the M1. Therefore, the performance is now near the M1 Pro with 8 cores. The passively cooled MacBook Air may however suffer from throttling in longer load scenarios.
Furthermore, the SoC integrates a fast 16 core neural engine with a peak performance of 16 TOPS (for AI hardware acceleration), a secure enclave (e.g., for encryption), Thunderbolt / USB 4 controller, an ISP, and media de- and encoders.
The Apple M2 includes 20 billion transistors (up from the 16 billion of the M1) and is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is rated at 20W what we also measured under CPU load.
The AMD Ryzen 9 5950X is a high-end 16-core, hyperthreaded (SMT) Vermeer Series desktop processor. With 32 threads, the new flagship offers as many threads as the AMD Ryzen 9 3950X. Introduced on October 8, 2020, the Ryzen 9 5950X is the fastest 16-core processor and is specified at 105 watts TDP.
The Ryzen 9 5950X runs at 3.4 GHz to 4.9 GHz (single core). Wen all 16 cores are loaded, up to 4.5 GHz are still possible.
The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen 2, because now a CCX consists of up to 8 CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity fabric should now reach clock rates of up to 2 Ghz, which in turn allows a RAM clock of 4,000 MHz without performance loss.
Performance
The average 5950X in our database matches the Core i9-12900K, the Core i9-12900HX and also the Ryzen Threadripper 2970WX in multi-thread performance, making this Ryzen a great processor for pretty much any task imaginable as of mid 2022.
Power consumption
This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 105 W. It will, however, happily consume much more than that as long as the cooling solution is able to handle the heat - even before one starts considering the possibility of overclocking the thing.
The Ryzen 9 5950X is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
