The performance of the R9 7845HX is significantly faster than the old top model Ryzen 9 6980HX (8 Zen 3 cores, 5 GHz max) thanks to the higher core count, improved architecture and higher clock speed. The 7845HX is the second-fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7900X. The cores clock from 3 (base) up to 5.2 GHz (single core boost). It offers 12 of the 16 cores based on the Zen 4 architecture that supports hyperthreading (24 threads). The AMD Ryzen 9 7845HX is a fast high-end laptop processor of the Dragon Range series. The M2 Pro is manufactured in 5 nm at TSMC (second generation) and integrates 40 billion transistors.ĪMD Ryzen 9 7845HX ► remove from comparison

The integrated graphics card in the M1 Pro 10-core offers all 16 of the 19 cores.įurthermore, 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 old M1 Pro 8-core should be noticeably slower. The multi-threaded performance should be slower, as the M2 10-core has two p-cores less (and 2 e-cores more) but the single-threaded performance should be better due to the faster clock speed and architectural improvements.

The performance of the M2 Pro 10-Core should be similar to the old M1 Pro with all 10 cores.

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. CPU and GPU can both use the 24 MB SLC (System Level Cache). 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. 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 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). It offers 10 of the 12 cores available in the chip divided in six performance cores (P-cores) and four power-efficiency cores (E-cores). The Apple M2 Pro 10-Core is a System on a Chip (SoC) from Apple that is found in the early 2023 MacBook Pro 14 and Mac Mini entry level models. Apple M2 Pro 10-Core ► remove from comparison
