The i7-950 is a first generation Core processor which is now three generations and four years old. The 950 was included in the group test as a reference for how fast processors were back in 2009. This particular generation of processor heralded the 4 core 8 thread configuration that Intel has been kitting its top end processors with ever since. In terms of real world performance based on single core horsepower (most applications are still unable to make use of multiple cores concurrently), with a PassMark Single Thread score of 1320 the i7-950 is approximately 50% slower than its modern day equivalent, the i7 4770K[Feb '12 CPUPro]

MORE DETAILS

The Core i3-3225 Ivy Bridge processor offers both superb real world performance and excellent value for money. For raw single threaded performance the i3-3225 scores 28% lower than the i7-3770K but costs less than half as much. At first glance one might assume that I am crazy for recommending a puny Core-i3 over the mighty Core-i7's but for real world consumer use there is simply no point in having 4 cores and 8 threads, they will hardly ever be used. All of the third gen Ivy Bridge Core-i3s are superb but the i3-3225 sports the slightly more 3D capable HD 4000 Graphics vs the HD 2500 offered on the other models. For real-world performance in an energy efficient package with modest on-board graphics, this is a superb choice. For most use cases including: email, surfing, watching movies, listening to music and office apps, this processor will deliver almost as good an experience as any other processor on the market. [Jun '13 CPUPro]
