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 7 7840S is a fast high-end laptop processor of the Phoenix series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache. The processor is exclusively available in Lenovo laptops but the specs are similar to the regular Ryzen 7 7840HS.
The performance of the R7 7840S is only slightly below the fastest model, the R9 7940HS, as the clock speed difference is only minimal (e.g. -100 MHz / 2% slower single core boost). Therefore, the CPU should also perform slightly higher than the old top model Ryzen 9 6980HX (8 Zen 3 cores with up to 4.9 GHz) at 54W TDP and Ryzen 9 6980HS at 35W TDP. Compared to the higher end Dragon Range series, the 7840HS should be similar to the Ryzen 7 7745HX (also 8 Zen 4 cores, max 5.1 GHz, 55W TDP, 32 MB L3).
The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.
The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured in the modern 4nm process at TSMC. The TDP can be configured between 35 and 45 Watt.
The Apple M2 Pro is a System on a Chip (SoC) from Apple that is found in the early 2023 MacBook Pro 14 and 16-inch models. It offers all 12 cores available in the chip divided in eight performance cores (P-cores) and four power-efficiency cores (E-cores). The E-cores clock with up to 3.4 GHz, the P-Cores up to 3.7 GHz (mostly 3.3 GHz in multi-threaded workloads and 3.4 GHz in single threaded).
The big cores (codename Avalanche) offer 192 KB instruction cache, 128 KB data cache, and 36 MB shared L2 cache (up from 24 MB in the M1 Pro). The four efficiency cores (codename Blizzard) are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. CPU and GPU can both use the 24 MB SLC (System Level Cache).
The unified memory (16 or 32 GB LPDDR5-6400) next to the chip is connected by a 256 Bit memory controller (200 GB/s bandwidth) and can be used by the GPU and CPU.
Apple states that the M2 Pro has a 25% higher performance than the M1 Pro in Xcode compiling.
The integrated graphics card in the M1 Pro offers all 19 cores.
Furthermore, the SoC integrates a fast 16 core neural engine (faster than M1 Pro), a secure enclave (e.g., for encryption), a unified memory architecture, Thunderbolt 4 controller, an ISP, and media de- and encoders (including ProRes).
The M2 Pro is manufactured in 5 nm at TSMC (second generation) and integrates 40 billion transistors.
