I'm thinking about buying a computer and I narrowed it down to two. They pretty much the same in terms of hardware but one has Intel Core i7-980X six-core Extreme Edition [3.33GHz, 1.5MB L2 + 12MB shared L3 cache] processor and the other one is Two 2.93GHz Quad-Core Intel Xeon
So which processor is better, faster? In the Intel Core i7, processor speed is 3.33GHz, but the other one says, Two 2.93GHz, does that mean that it's processor speed is 5.86GHz? (2.93+2.93=5.86)
First, the easy question. No, you don't add speeds. Two cars going 50 miles per hour do not somehow make 100 miles per hour.
Unfortunately, you didn't specify which Xeons your talking about. I'm assuming you mean the X5670. If this is not the CPU you are talking about, let me know and I'll update my answer.
The X5670's cores are about 15% faster than the 980X cores. Plus, the dual-Xeon system has 8 cores and the 980X system has 6. So it's a win all around for the dual-Xeon system.
Whether or not this is worth the massive ($1,600-ish) cost difference, however, depends on what you plan to do with it.
