Intel’s most popular family member is more adaptable than ever and unlocked. The 2nd generation Intel Core i5-2550K processor delivers an even better automatic performance increase with Intel Turbo Boost Technology 2.0 and is overclocking-enabled for the flexibility to set your systems specs the way you like.

FULLY UNLOCKED FLEXIBILITY AND FREEDOM With its fully unlocked multiplier, the Intel Core i5-2550K processor allows full control over the processor core/turbo and DDR3 ratios as well as power and current limits for the best possible overclocking results. Intel’s cutting-edge 32nm micro-architecture with 2nd gen Hi-K+ metal gate process delivers the 2nd generation Intel Core processors with higher performance at lower power, thus better overclocking capability. (Intel P67/Z68 Express Chipset required for core and memory overclocking)
INTEL TURBO BOOST TECHNOLOGY 2.0 More 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 and graphics 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 CACHE Intel 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 DDR3 MEMORY CONTROLLER Integrated memory controller enables two channels of DDR3 1333 MHz memory, resulting in up to 21 GB/sec memory bandwidth. Plus the memory controller's lower latency, efficient prefetching algorithms and higher memory bandwidth delivers amazing performance for data-intensive applications.
INTEL ADVANCED VECTOR EXTENSIONS (INTEL AVX) Intel AVX is a new 256 bit instruction set extension to SSE and is designed for applications that are Floating Point (FP) intensive. Intel AVX improves performance due to wider vectors, new extensible syntax, and rich functionality. This results in better management of data and general purpose applications like image, audio/video processing, scientific simulations, financial analytics and 3D modeling and analysis.
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.

N/A 1/9/2013 5:06:49 PM Tech Level: 5/5 Ownership: 5/5 Verified Owner	Rating: 5/5Speedy thing Pros: Fast beyond believe, especially when clocked up. People have said that they were able to overclock this to 5.0GHz, though I haven't tried. I got it to 4.4GHz, and was content with that, so it's clocking speeds are great. It works wonderfully with both Linux and Windows(7 and 8), so there are no OS requirements for it to work well Cons: No integrated graphics. Usually not a problem, but I was having trouble with my video card awhile back, and that made it a little difficult to figure out what was wrong at first. Other Thoughts: I picked it up about a year ago for $240 bucks, definitely worth the price tag. Too bad I got it before they ivy bridge series.. 1 out of 1 people found this review helpful. Did you?

zach 11/11/2012 10:18:17 AM Tech Level: 3/5 Ownership: 4/5 Verified Owner	Rating: 5/5Great! Pros: Works great. Overclocks 4.5ghz without touching voltage. Antec cooler, only get 68C for a max temp on prime95. Cons: Should be cheaper IMO, compared to the 2500k they seem to run about the same OC so there is no advantage there.

bhamil 11/9/2012 2:05:39 PM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Great CPU! Pros: Fast processor, runs cool under high loads, no onboard graphics. Cons: None! Other Thoughts: I bought this CPU in February to rebuild and upgrade my old AMD Phenom computer. I have been very happy with this processor's performance. I have no problems with having multiple programs running, and have no lag. Great processor! Did you find this review helpful? Thanks for the valuable feedback you provided!

Spagnacious 9/30/2012 9:52:18 AM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5SMOOTH OPERATOR Pros: Clocked to 4.7Ghz on 1.356Vc with 36c/67c (Idle/Load). Low end closed loop cooler worked just fine. Lots of myths is right, I STILL can't find a verified opinion about whether this baby has an active or inactive (read contributes to heat) IGP (GPU) circuit. Cons: Intel isn't giving us a price break, even with the lack of GPU because they know that us Geeks know it is a winner. On the other hand Intel isn't a philanthropic organization. Other Thoughts: If you are not a big-time Gamer, Folder or looking for a "Trophy" chip, this is one SMOOTH puppy! I run 3 2560x1600 displays on 2 cards with no hiccups.
