As the first level of Intel’s Sandy Bridge processor family gave you the visuals you want built-in, the 2nd generation Intel Core i3 processor offers a fast, responsive, and visually immersive PC experience available to everyone. With the 2nd generation Intel Core i3 processor, you get built-in visuals that offer a rich and exciting set of capabilities for a stunning and seamless visual PC experience with no additional hardware required. Also featured is Intel Hyper-Threading Technology, which enables each processor core to work on two tasks at the same time, giving you smart multitasking performance that moves between applications quickly and without hesitation. This is where to start for visibly smart performance.

  • newegg Fully Integrated Microarchitecture on 32nm Process The Intel microarchitecture codename Sandy Bridge is an incredible leap in processor integration and manufacturing introduced in the 2nd generation Intel Core processor family. Manufactured entirely on Intel 32nm process technology, Sandy Bridge unifies processor cores, memory controller, last-level cache (LLC), and graphics and media processing. Such tight integration enables a host of performance and efficiency improvements, including fast access by cores and graphics to shared data in the last-level cache to accelerate graphics processing, fewer buses over which data and signaling must travel for faster processing, and more memory bandwidth for the cores to boost system performance.
  • newegg Intel Hyper-Threading Technology (HT Technology) Intel Hyper-Threading Technology delivers thread-level parallelism on each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on the multi-threaded software of today and tomorrow.
  • 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 Built-in Visuals The 2nd generation Intel Core processors integrate a suite of technologies built right into the processor that deliver stunning visual experiences. Intel Quick Sync Video is breakthrough hardware acceleration that makes fast work of creating, editing, synchronizing, and sharing your videos at home and on the internet. Built-in Intel HD Graphics 3000 enables superior mainstream gaming and 3D experiences – without the need for a discrete graphics card. Enjoy stunning visual quality and color fidelity for spectacular HD playback and immersive web browsing with Intel Clear Video HD Technology, plus the ultimate 3D visual experiences seamlessly from your PC with Intel InTru 3D Technology.
  • 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 eggsIntel 2105

Pros: Man I love this thing. I wanted to wait a while before I wrote the review to make sure it wasn't just the blazing speeds out of the box, and let me tell you something: IT IS AMAZING!!!! I love this dual core CPU, and for a good price, you get quality. After a few months this guy has held MANY applications opened, all CPU intensive too. You absolutely cannot go wrong with one of these CPUs, and with the speed you'll get, I doubt you'll feel different.

Cons: Can't have any cons on a product that doesn't perform sub par!

5 out of 5 eggsGood processor for an HTPC

Pros: Fast, solid, good price.
My HTPC runs smooth and never uses 100% of this processor.

Cons: None that I can think of

Other Thoughts: Using it in HTPC and it works great.

5 out of 5 eggsAmazing in HTPC

Pros: This is an amazing CPU for HTPC builds. You can't beat the price/performance ratio that the i3-2105 offers. I have this installed in a small form-factor mini-ITX HTPC build and it runs fast and quiet. It handles all of the common PC tasks very nicely, including over the air HD 1080p recording and playback of HD video. Highly recommended.

Cons: None.

5 out of 5 eggsWell more...

Pros: This little duel core has put out some power that I would have never expected to see, upgraded a budy of mine to a pc with this cpu, went from an old AMD Athlon x2 to this, and I'm impressed, Runs cool, Super Cool, and even for some "heavy" gaming this thing paired with a HD 5770, can run games like AION on max at 1600x900 with nothing lower than 45 FPS.

Cons: Disappointing that the price for this hasn't dropped all that much, but nothing to knock points off for.

5 out of 5 eggsVery fast in the price range

Pros: This is a great entry level CPU. On chip video will play games at moderate levels. I was impressed at the speed.

Cons: Video limited for newer games.

Other Thoughts: The on board GPU will not replace a nice graphics card. But it will do a nice job for an entry level machine or a young child.
