Xeon or i7, what's the difference?

[marat85]

Hi, is there any difference between these two processors in terms of performance:

1. Intel Xeon E5-1620 v2
Clockspeed: 3.7 GHz
Turbo Speed: 3.9 GHz
No of Cores: 4 (2 logical cores per physical)
Typical TDP: 130 W
Single Thread Rating: 1956
CPU Mark: 9495

and

2. Intel Core i7-3770
Clockspeed: 3.4 GHz
Turbo Speed: 3.9 GHz
No of Cores: 4 (2 logical cores per physical)
Typical TDP: 77 W
Single Thread Rating: 2069 (+5.7%)
CPU Mark: 9299 (-2%)

Is there any real life difference in computing performance between these two processors?
The only noticeable difference I can spot so far is that the Xeon is 1.68 times hotter than the i7, why so? What makes the Xeon so much hotter if they both have the same number of cores and performance scores as well?

The difference is minimal but the reason the Xeon is hotter is due to the higher TDP.

- Xeon support ECC memory.

- Xeon is more an industry platform / server platform.

The TDP is higher because the Xeon E5-1620 is a Sandy Bridge-era processor, and manufactured with a 32nm process. The i7-3770 is an Ivy Bridge processor manufactured with a 22nm process, so needs less power. (Ivy Bridge is a die shrink of Sandy Bridge - same design, just shrunk down from 32nm to 22nm, with a few minor bug fixes and performance improvements.)

That particular Xeon also lacks integrated graphics, using the space for additional L3 cache (10 MB vs 8 MB on the i7).

In real world use, ie gaming, I'd rather have the cooler running CPU if prices are about the same. For most average users Xeons make sense only if the particular Xeon can be had at a great price. The typical user knows what an i7 is, and so is more likely to buy one. Not as many know about Xeons, so sometimes they are sold for much less.

The Xeon E5-1620v2 and i7-3770 both Ivy Bridge with 22nm process... yet the difference in TDP is huge...
