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.

  • newegg 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)
  • newegg 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.
  • newegg 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.
  • newegg 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.
  • newegg 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.
  • newegg 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.

5 out of 5 eggsAwesome CPU

Pros: This processor is amazing. It's fast out of the box, you can obviously ramp it up beyond belief without ever using water cooling. This quad core chews through everything. Installing was a breeze, booted right up. I love it.

Cons: I'm going to put this just as many others do and it IS a valid complaint - the included cooler is so-so at best, and terrible at worst. Yes, it works, but beyond that it doesn't do much.

Here's my reasoning - the K series chips are Intel's chips made to go faster and all that jazz - we know this. It's unacceptable that the included cooler keeps it at barely OK levels at normal speeds. If you purchased a Corvette, you don't need to do ANYTHING to it - it's fast right off the lot. The included radiator(s) keep the engine more than cool. You can make the Corvette do 2-3x the speed limit with ease and it's not going to overheat. Chevy isn't dumb and realizes people will do this with their sports car, even though you can't legally go over 75mph just as this chip 'shouldn't go over 3.8ghz.

Other Thoughts: I can't say it enough, this processor is a beast. I love it, never a bottleneck in my system. I got mine from a local brick and mortar store on a fire sale. I could have spent approximately $50 for an i7-2600 (not the K) but I figured my needs don't require hyperthreading and the extra cache wasn't worth it when I could get more RAM or a much better FX card.

5 out of 5 eggsSpeedy 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..

5 out of 5 eggsGreat!

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.

5 out of 5 eggsGreat 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!

5 out of 5 eggsSMOOTH 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.
