Vastly more CPU threads
6 more CPU threads. More threads result in faster performance and better multitasking.
Higher GeekBench result
Higher GeekBench result. This is a cross-platform benchmark that measures the performance of the CPU. (Source: Primate Labs, 2015)
Considerably faster CPU clock speed
4 x 2.8GHz
2 x 1.3GHz
4.31x faster CPU clock speed
Vastly faster GPU clock speed
400MHz faster GPU clock speed. The graphics processing unit (GPU) has a higher clock speed.
Uses hyperthreading technology
Many of Intel's processors use hyperthreading, which means that each core of the processor can work on two threads at once instead of most processors which work on a single thread per core. This means you can have significant performance gains in certain applications.
Newer version of DirectX
Newer version of DirectX. DirectX is used in games, with newer versions supporting better graphics.
Appreciably bigger L3 cache
4MB bigger L3 cache. A larger L3 cache results in faster CPU and system-wide performance.
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
AVX is used to help speed up calculations in multimedia, scientific and financial applications, as well as improving Linux RAID software performance.
Has Intel Quick Sync Video
This allows very fast video transcoding times, for example when ripping a DVD or Blu-ray to your computer.
