  • newegg Intel Revolutionary 22nm transistors technology Transistors 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.
  • 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 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 memory controller Integrated 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.

5 out of 5 eggsGreat CPU

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

Other Thoughts: 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

4 out of 5 eggsGreat HTPC CPU

Pros: * The lower power usage allows it to run cool in my quiet HTPC even with the fans turned down low.
* Fast and responsive with Windows 7 / 8.
* Integrated GPU (HD 2500) is good enough for hardware assisted video decoding.
* For services that don't support accelerated video the CPU is powerful enough to decode on its own.

Cons: * For casual gaming the integrated HD 2500 GPU is not as good as the HD 4000. This is obvious but worth pointing out.

5 out of 5 eggsAwesome!

Pros: Very fast, low power. Come with heat sink.

Cons: Creates heat still? Nothing really

Other Thoughts: I can't wait for CPUs to be efficient enough to not need a fan, but this one is pretty good.

5 out of 5 eggsperfect for my needs

Pros: Using this CPU with the Intel BOXDB75EN LGA 1155 Intel B75 SATA 6Gb/s mother board, I was able to play DC Universe on line flawlessly, this was with no Graphics card. The CPU runs cool and quiet even with the stock fan. I dont over clock, and I am very content with the CPU performance.

Cons: The inability for the 4 cores to share a process seems bad, but I haven't see it run into any lag issues yet.

Other Thoughts: Hearing that awful crunch sound when installing the CPU brought back bad memories when I used to crack old AMD glass core CPUs. Don't worry, it's not a bad sound when you hear it installing this CPU

5 out of 5 eggsGood new start

Pros: I'm not an avid gamer but normal use for the first 5 min kept the temperature at 35 c (95 f) with the stock fan. The Stock fan was quiet as compared to other stock fans I've seen. So long as you dont force anything and take your time, the installation is easy.

Cons: none.

Other Thoughts: The Chip install was new to me. I never knew there was a horrid crunch sound made when the CPU was installed. It reminded me of the days when the old AMDs had that glass core and if you heard a crunch, you cracked the core. So to let anyone else know, that sound you hear when installing this, is normal. I'm still out on if having a smooth CPU is better than one with pins, but from a transportation and handling stanpoint, I can see why they went that way.

5 out of 5 eggsAwesome little chip

Pros: Ivy Bridge is a great step forward for Intel. I upgraded to this from a 1st Gen Core2Duo chip. I like that it's more efficient, less power draw means less heat, too. It combines with the rest of my build to add up to AMAZING boot times. Almost maxed out the Windows 7 ratings.

Cons: Stock cooler, I guess.

Other Thoughts: I haven't tried overclocking this thing, yet. I pushed the heck out of my old Core2Duo, but jumping from Socket LGA775 1.86GHz(x2) to Socket LGA1155 2.8GHz(x4) is a huge performance leap as it is!

5 out of 5 eggs

Pros: Speed, power draw, temperature

Cons: Price, motherboard price

Other Thoughts: 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.

5 out of 5 eggsFast for 65 watts

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

Other Thoughts: CPU i5-3450s
MEM GSKILL sniper 1866 4gbx2
HD OCZ 60gb ssd
HD2 WD 1TB black
HD3 WB 3TB USB 3.0
VCARD XFX FX-775A-ZNP4 Radeon HD 7750 (best low power single slot!!!)

5 out of 5 eggsUpgrade from i5-750

Pros: * Low Power usage
* Runs cool
* Perfect price point

Cons: * Didn't notice a large real world performance increase over previous i5s.

Other Thoughts: 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...
