Want a processor with dramatic performance gain at low operating voltage? The new Intel 22nm 3-D Tri-Gate transistors technology employed in the Intel 3rd generation Core processor makes your dream come true with an incredible leap in combination of performance and power efficiency. The 3rd generation Intel Core i5 processor delivers even more performance automatically when you need it and now a better visual PC experience built-in. With Intel Turbo Boost Technology 2.0, the 3rd generation Intel Core i5 processor increases your PC’s speed automatically for your demanding applications. It also includes new built-in graphics with DirectX 11 support and a rich set of new features for a stunning and seamless visual PC experience with no additional hardware required. That’s visibly smart performance with a boost. Moreover, the 3nd generation Intel Core processor with alpha suffix “S” that indicates “Performance Optimized Lifestyle” has a lower TDP of 65W, ideal for both performance and energy conscious users.
Intel Revolutionary 22nm transistors technologyTransistors have now entered the third dimension. Intel brings 22nm 3-D Tri-Gate transistors (the core of microprocessors) to its third generation Core processors Ivy Bridge. Intel's 3-D Tri-Gate transistors are an important innovation needed to continue Moore’s law and deliver an unprecedented combination of performance and power efficiency. By forming conducting channels on three sides of a vertical fin structure, Tri-Gate transistors can have multiple fins connected together to increase total drive strength for higher performance. The new 22nm 3-D Tri-Gate transistors can deliver up to 37% performance increase at low voltage and more than 50% power reduction at low voltage.
Intel Turbo Boost Technology 2.0More intelligent, energy-efficient, and dynamic than previous generation, Intel Turbo Boost Technology 2.0 gives you accelerating performance when you need it. It delivers an even greater automatic speed increase by allowing processor cores to run faster than the base operating frequency for demanding applications if the processor is operating below power, current, and temperature specification limits.
Intel smart cacheIntel Smart Cache Technology dynamically allocates the shared cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from faster, more efficient cache subsystem resulting in significantly reduced latency for frequently used data and improved performance.
Integrated memory controllerIntegrated memory controller enables two channels of DDR3 1333/1600 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. Plus the memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
Built-in visualsThe visual features built into the 3nd generation Intel Core processor family deliver everything you need to enjoy a stunning and seamless visual experience. Intel Quick Sync Video and newly-added Intel Advanced Vector Extensions (AVX) make media processing incredibly fast. New built-in Intel HD Graphics with DirectX 11 support delivers discrete 3D graphics performance without the needed cost and power of a discrete graphics card, and features Intel Clear Video Technology that enhances video playback, image quality, and color fidelity for a premium visual experience. What’s more, add another dimension to what you see on your PC with Intel InTRU 3D technology which supports stereoscopic 3D Blu-ray playback in full 1080p resolution over HDMI 1.4 and premium audio.
Intel Virtualization Technology (VT-x)Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.

Pros: * Low Power usage
* Runs cool
* Perfect price point
Cons: * Didn't notice a large real world performance increase over previous i5s.
Overall Review: I purchased the i5-750 back in January of 2010 for $200. 2 and a half years later I purchased the i5-3450S for $200. Both CPUs sold for the same amount considering when they were brought to market and that's impressive. I've never benchmarked either CPU; instead I gauge performance in applications and gaming to see if I can recognize a noticeable difference. I didn't really notice much of a increase, but that's not a bad thing. The i5-3450S uses less power, runs cooler and the cores aren't as stressed as the old i5 (according to Windows Task Manager). I would equate it to buying a newer model of the same car you have now. There are small improvements, but it's not going to be a world of difference. The computer industry as a whole seems to be slowing down. My old i5 still has plenty of power to run every program/game on my computer perfectly. If you buy this CPU you won't need to upgrade for at least 3 years or so. Your GPU on the other hand...
Pros: This is a true quad core and only 65 watts. drops down to 1.6ghz at idle using almost no power.
Using as a media server, HTPC, and low power gamer.
Cons: Stock heatsink, it fits in my mini case but at idle it sits @ 40C
thermaltake slim X3 would work, just not with my MB (blocks airflow) going to try silverstone nt07

Overall Review: I bought an i5 setup to replace the process in my WHS. Used to be a PII-x4 945 system that drew 100w at idle. With this processor and a P8H67-M Pro the system draws only 65W!!!! AMAZING.
Pros: runs cool, tears through handbrake, turbo boost is great for times when single threaded applications need it
Cons: i have this weird issue that turbo kicks in and won't turn down without reboot. i believe either do to need of a BIOS update or some funky glitch
Overall Review: the i7 3770 is faster in handbrake but its only noticeable in huge batches of encoding. also, speed is somewhat limited by hard drives so the i5 is a better deal to me. downside could be the HD2500 but i use a passive gpu as even the near bottom GPU is still above the HD4000 for most anything

Pros: You can overclock this to a degree. The standard turbo boost multiplier on this is 35. I can ramp it up to 39 (3.9 Ghz) on my Asus mobo. I can also probably increase base clock from 100mhz to 110 etc, but I'm not overclocker savy enough to try.
This appears to be the same CPU as the i5-3450 with just a lower default clock rate. Extra power savings in idle mode maybe?
Runs very cool, even on 39x, I've yet to see it past 55C.
Cons: The fan on does not have a good PWM curve. At 0% speed setting the fan speed is 1000 rpm, at 100% its 1990 rpm. Ok, but at 40% speed setting its 1021? At 50% its 1029? At 60% its 1250, 70% 1450, 80% 1560, 90% 1850. I had to adjust the CPU fan speed temperature curves to accomodate the fact that 0-50% fan speeds are all the same.
Pros: * Low Power usage * Runs cool * Perfect price point
Cons: * Didn't notice a large real world performance increase over previous i5s.
