However, because the Core i3 is the low-end Nehalem variant, most of these features are disabled or not relevant - the Core i3 is a dual core processor and Turbo Boost is disabled, but hyper-threading is enabled. The Core i3 is the slowest variant of the Nehalem based processor.
The fastest Core 2 Duo desktop processor has a speed of 3. You might therefor expect that the Core 2 Duo would have the edge - particularly when you consider that the Core 2 Duo costs almost three times as much if you buy it individually - but in fact the Core i3 is faster, and often by no small margin.
The Core i3 is faster even in single-threaded applications, but the performance gap really widens in multi-threaded applications. This is because the Core i3 has hyper-threading, which turns the two real cores into four virtual cores. Windows works with the Core i3 as if it is a quad-core processor. These results remain true in the mobile space, as well.
Core i3 processors punch at least Mhz above their weight in single-thread applications, and are virtually always faster in multi-threaded applications, no matter the clock speeds of the Core 2 Duo and Core i3 processors you are comparing. A look at the technical specifications of the Core i3 processors automatically puts them into a negative light when it comes to power consumption.
Another feature found on the i3 that is not available on other equivalent dual-core processors is hyperthreading. Hyperthreading provides efficient resource utilization and allows multiple threads to run parallel in each core. Intel claims that HT processors like the i3 retain their responsiveness even when running complex applications like video editing software. The biggest contributor to the leap in performance of the i3 from other dual cores is its move from the 45nm architecture used before to the 32nm architecture.
The smaller width allows for more transistors within the same silicon chip; hence the inclusion of the DMI and the GPU. It also means less power consumed and less heat generated while performing better and faster than its predecessors.
Power consumption is now becoming a more important benchmark in processors due to many people moving away from traditional desktops into the more mobile and battery-operated laptops.
The i3 is a dual-core processor. The i3 is on the 32nm architecture while dual cores are on the 45nm architecture. Cite APA 7 , l. Difference Between Dual Core and i3.
