Summary: I wanted to build a passively cooled home theater PC (HTPC). When I looked at the benchmarks for comparable systems in my price range, this won hands down, with 25-45% performance edge and 35W opposed to 50+ watts. With the stock fan, I routinely run at 33-36C and rarely even approach the high 40s when really stressing the CPU.
Summary: I bought this because I wanted a cheap Intel CPU for a computer and what I got was pretty good. The fan included was also nice as it easily snapped into the motherboard. I've had no problems so far with this CPU despite running it at 100% 24/7 for work related purposes, it hasn't failed or overheated on me once.
Summary: I bought this for its performance and low power consumption. I am more than happy with the build that centers around this CPU, a Mini-ITX setup. Performance is on par with my old Core 2 Quad 8300..benchmark wise, but it feels way zippier in real use.
Summary: One of the distinctive features of the processor is Hyper-Threading technology. The Hyper-Threading allows this microprocessor to execute twice as many threads. The CPU supports AVX and F16C instructions, that appeared in modern CPUs not too far ago. Although these extensions are not widely used in programs yet, their support should improve in future apps. Power consumption of the CPU is lower.
Summary: Support ECC RAM. VT-x but not VT-d. 35 W TDP. Similar in performance to the the Xeon E3-1220L V2 processor, which adds VT-d and has a jaw droppingly low TDP of 17 W. However, the E3-1220L V2 is very hard to acquire, and about 2x as much money. For quiet, low power server builds, even with low end virtualization workloads, this CPU is hard to beat.
Summary: This CPU is rinning on a Mini-ITX in a not-so-normal PC... but anyway. I'm running Folding full throttle and it is only a little slower than my Xeon 3440. The i3-3220T is 2 generations newer, but geez, my Xeon is not that old! And this CPU runs way cooler and way faster than my i3-530, which actually is not a very hot CPU at all. I have never had a heat problem with an Intel CPU (well, not in years...
Summary: Powerful to run many 4GB virtual machines and not generating a lot of heat. I think there is no point buying i7 etc. I moved down from a Q9550 quad core 95Watt to this processor and i don't feel loosing any speed etc for most of the application. This processor run the whole day in a close cabinet and barely feel warm.
Summary: Got this last summer for a (relatively) low power HTPC build and have found it handles everything we've thrown at it. The on board graphics is more than adequate for viewing HD movies and is able to do transcoding in the background without skipping a beat. Recently migrated all the parts into a low profile case to keep the wires out of a new puppy's reach.
Summary: Meets all expectations. Using this with an Intel DH77DF, Kingston Value RAM 4GB 1600MHz PC3-12800 DDR3 Non-ECC CL11, and mini-logic 60WPS, running Win7. It is running cool (no overclocking). I have only has this up and running for two week, and have yet to measure power usage, but I expect it o be around 5W idle and 17W running Win7 MCE.
