Product Overview Improved on-board graphics
Perhaps the biggest improvement is in the area of embedded graphics. With this new generation of CPUs the graphics are now known as HD 4600 and with the change of name comes about a significant improvement in performance, especially for 3D games and applications. Furthermore, up to three separate displays can now be driven simultaneously, reducing the need for a discrete graphics card where triple-head monitors are required.

Guide to suffix variants
The single-letter suffix on each model of processor denotes whether it can be overclocked (K), or is low-power (S) or ultra-low power (T). Note that 'power' in this context refers to electrical power, not computational power. We recommend S or T suffix processors where cool-running / energy saving is required, or K-series processors where maximum performance is desirable and sufficient cooling can be provided accordingly. Features Variant performance comparisons
In terms of computational performance, Intel don't provide official figures for their processors because so much depends on other hardware such as motherboard, type of memory, etc. So instead, we would suggest that potential customers refer to real-world empirical performance benchmarks such as those published by Passmark and quoted in the specification table below. These allow a simple comparison to be made between the different variants of processors and are based upon the averaged results of many users' PC systems across the world. An opinion about the relative performance differences between each model of processor can therefore be quickly formed.

Core i5 / Core i7 differences
In essence, Core i5 processors are designed to be more affordable, lower performing versions of the Core i7 parts. There will certainly be some overlap in performance between the highest-end i5 processors and the cheapest i7 versions, but in essence the Core i5 range has a smaller cache (6MB rather than 8MB), a fewer maximum number of threads (4 not 8) and the omission of Hyper-Threading (HT Technology).

New 4th Generation CPUs
New 4th Generation CPUs
Date Issued: 9th May 2014

Intel launched a bevy of Haswell Core processors last June. Presented in a LGA1150 form factor and therefore physically different to the LGA1155 Ivy Bridge processors of the year before, new chipsets were also launched to support these new chips.

Date Issued: 1st Jun 2013

With PC and mobile converging quicker than ever before, Intel needs to reassert its presence in portable devices with an architecture that can scale across multiple platforms. That quest begins with the introduction of the fourth-generation Core processor family, codenamed Haswell.

Rated 5 out of 5 by Optimal processor I've select this processor for power consumption. In essence it's the same as other same class processors with TDP set at 45W. In my books that is optimal performance at very cool temperature. Used it both for work and games and have nothing to complain about. 14 December 2015
Rated 5 out of 5 by Fantastic Processor This particular processor model fills a strange niche; it's low-energy, but has extremely good performance, which is going to limit who is interested in it. Most people looking for low-energy have modest needs, so an i3 is often plenty, while those looking for high performance don't often care about going with a 65W or higher TDP value. Where this processor really shines however is in. small form factor systems for professionals, where you still need plenty of CPU performance for running modest workloads or a lot of multi-tasking. Anything that is space-constrained but requires strong performance will benefit from this processor's impressive performance. I opted to pair mine with an Akasa Euler passively cooled thin Mini-ITX case (also available on Scan); the Euler recommends 35W as the upper limit, but this processor seems to run well enough with a bit of throttling under heavy load (and the case becomes an extra radiator for the room). Even in these conditions the performance really can't be faulted, as it can handle Handbrake encoding on all eight logical cores. While no-one looking for serious gaming performance should settle for integrated graphics, the HD4600 on this processor is also worthy of note; it still outperforms the HD5000 (only Iris branded parts are better), and can easily handle modest titles like Civilisation V and Beyond Earth, plus it does a good job of running Skyrim at HD resolutions; especially with the CPU clout to back up these processor-bound titles. It can even run unreasonably demanding tasks like Second Life (albeit with of the really high-end shaders turned off) without complaint. So, while it can be a pain to get since it needs to be ordered in especially (and I did encounter additional delays beyond the initial estimate), this is a very capable processor for the amount of power it sips. It flies through both single-threaded and multi-threaded workloads without lagging all that far beyond more power hungry models, and it could make a great processor for a powerful, but small form-factor, gaming system, if paired with the right GPU. 09 November 2014

Answer: 
Yes, you do need a third party cooler. It comes in a tiny match box. OEM means that it's for computer builders. RETAIL will come with a cooler, OEM comes only with processor and no cooler.
It's great if you planning to put something more efficient/silent or water cooler. I've used AIO similar to this one: LN61965.
Compared to stock Intel Cooler than you would pay for in RETAIL box, this gives me at least 10 degrees lower CPU and much quieter oepration.
