Intel Core 2 Duo T6670 vs Apple M2 Pro 10-Core vs Intel Core 2 Duo P7450
Intel Core 2 Duo T6670
► remove from comparisonThe Intel Core 2 Duo T6670 is an entry level laptop processor based on the Penryn core. It offers only 2 MB level 2 cache and a mediocre clock rate of 2.2 GHz. Compared to the similar T6600, the T6670 offers Virtualization VT-x and a higher maximum temperature of 105°C.
Apple M2 Pro 10-Core
► remove from comparison
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. 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 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.
The performance of the M2 Pro 10-Core should be similar to the old M1 Pro with all 10 cores. 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 old M1 Pro 8-core should be noticeably slower.
The integrated graphics card in the M1 Pro 10-core offers all 16 of the 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.
Intel Core 2 Duo P7450
► remove from comparisonThe Intel Core 2 Duo P7450 is a dual core processor for laptops. It features 2.1 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but Trusted Execution and Virtualization (VT-x) are disabled.
The P7450 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 800 MHz to save power (in idle mode).
