The E6750 is a 2.66Ghz CPU that was introduced in Q3 2007. That means that single core performance went up only 8% per year on average.<p>Compared to the improvements we made in the decades before that, that&#x27;s really poor.<p>I have a i7-2600k (quad core 3.4Ghz, 95W TDP, HT) that was introduced in 2011. Five years later, it still is not significantly slower than recent CPUs by Intel unless they take advantage of new CPU features. It sold for around 250€ back then. Today, for 250€ you can buy an i5-6600k (quad core 3.5Ghz, 91W TDP, no HT).
The only big improvement in the i5-6600k is the GPU (which I don&#x27;t use).
