Like the superheroes of old, the AMD Phenom II streaks out of the night to lay waste to your enemies with three 2.8GHz cores having L1 and L2 caches for each core and 6MB of L3 cache to be shared to handle really heavy loads or large data sets.

Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB/s of bandwidth. Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 memory controller delivers an amazing 37GB/s of processor-to-system bandwidth. This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores.

You'd think that all of this power would be too hot to handle. Think again. AMD's Cool'n'Quiet 3.0 technology works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.

  • newegg AMD64 Triple-core Technology AMD64 is designed to enable simultaneous 32- and 64-bit computing with no degradation in performance. With Triple-Core technology, three complete processor cores on a single die run at the same frequency to deliver exceptional multi-tasking power, allowing users to surge through the most demanding processing loads, including advanced multitasking, critical business productivity, complicated visual design and modeling, serious gaming, and visually stunning digital media and entertainment.
  • newegg Integrated DDR2 and DDR3 DRAM Memory Controller The AMD Phenom II X3 Triple-Core processor is integrated with DDR2 and DDR3 DRAM memory controller capable of supporting registered and ECC DRAM. The integrated memory controller changes the way the processor accesses main memory, resulting in increased bandwidth, reduced memory latencies, and enhanced processor performance.

5 out of 5 eggsOverclockers Dream

Pros: AMD Overdrive took it to 3.5Ghz using my Coolermaster RR-H101-22FK-RA also purchased here. Core temps. running at 39.1
Price to performance ratio can't be beat.

Cons: No sticker in the box.

Other Thoughts: Never tried the fan but had planned on overclocking from the get-go.

5 out of 5 eggsGood deal at the time...

Pros: Able to unlock all four cores on an Asus M4A785-M m-atx MB. So far so good and seems stable. Like the unlocked multiplier feature for the future. When I bought the cpu the price was down at 119 so I got a good deal at the time!

Cons: Cheap heatsink and also compared against an i7-920, Q9550-S, and i5 processor at same frequency the above mentioned processors according to TomsHardware beat it in performance by a sizable amount and with less power wattage usage per mhz compared to the AMD Phenoms. Also the the X4-925 2.8ghz is going for $25 dollars less right now....

Other Thoughts: Despite performance rankings and power usage when I bought it at $119 made it a great deal and value per dollar spent. Can only guess that the X4 is cheaper because too many people are buying the X3s and unlocking the 4th core. Go figure....

5 out of 5 eggsAwesome

Pros: I just recently built my own machine and decided to use the 720 as my CPU because of the low cost (at the time) and the performance. This thing is leagues beyond my old athlon64x2 3800. I run high powered programs all at the same time and I experience no slow downs at all.

Cons: Dinky fan
stock thermal paste

Other Thoughts: I have not tried to OC this thing yet, as I don't want to mess around with the OC'ing abilities until I get a new cpu cooler. I purchased this when it was $ it is almost $40 more.

5 out of 5 eggsUnlocked 4th core

Pros: Runs cool. Idles at about 33C in my system. Noticeable jump in performance from old system. Unlocked the 4th core via BIOS with no problems.

Cons: Came with poor non-heatpipe fan/heatsink. My server which has a Phenom 9600 came with the heatpipe fan/heatsink. Will be swapping them sometime in the future. Wish it was still $119 when I bought it.

Other Thoughts: Purchased this and a Gigabyte GA-MA785G-UD3H for an upgrade from a Core 2 Extreme QX6700 (quad-core 2.66GHz) and Asus P5N32-E SLI. While the clockspeed isn't much higher, the 45nm architecture and low temperatures makes it easier to run harder and faster. CPU-Z views chip as a "Phenom II X4 20" Incredible performance upgrade for $220.

5 out of 5 eggsVery pleased with performance

Pros: Easily unlocked fourth core on Asus M4A78T-E mobo. Runs fine at 3.0 GHz with fourth core doing some video work, have not yet pushed up the frequency very far and stability tested it (system has only been assembled for a few days). Great price/performance tradeoff if you're willing to risk not having that fourth core be available.

Cons: None found to date.

5 out of 5 eggsGreat Chip!

Pros: Excellent value, especially of the fourth core can be unlocked. I was able to unlock the fourth core with zero problems on a Gigabyte GA-MA790GPT-UD3H motherboard. I've been running it with 4 cores at 3.2 GHz for two weeks now with no stability problems.

Cons: Not as fast as the core i5/i7 from Intel, but plenty fast for most users.

Included heatsink/fan was pretty cummy looking (small, aluminum only). I re-used the heatsink/fan from my previous build, which was a better copper heatpipe design that came with an Opteron 180 chip.

Other Thoughts: All in all, a great value. If you want to overclock, I'd suggest ordering a separate heatsink/fan with a better design.

5 out of 5 eggsSmokin Fast

Pros: AMD Quality, 4th Core unlocked @Vstock, Decent stock Cooler, Runs cool with stock cooler w/ 3 or 4 cores running even cooler with a Zalman. I haven't Played around with overclocking yet, but through my research most of these 720's will run around 3.2 @Vstock with stock cooler and around 3.8 with a slight V bump on aftermarket cooling.

Cons: doesn't cook breakfast ;)

Other Thoughts: AMD is notorious for taking a perfectly good CPU and Locking it to sell as a slower processor to meet demands. I remember back in the day of the Athlon Xp CPU's of them taking Xp2600 CPU and locking and selling them as a Xp1700. They stopped making CPU's under the Xp2600 but the demand was extremely high for the slower processors. I bought 3 of those and each was a OC machine. Taking them from 1466mhz stock up to 3400mhz running them on Air cooling. Any way there is no guaranty that every 3 core CPU can be unlocked and run stable, It would be a good bet that it can be. Most of your SB710 and SB750 boards will have the options to unlock the cores. I did it with a ASUS M4A785TD-V Evo . It took all of 10 sec. to do. AMD may not be as Fast as Intel but you get alot more bang for your buck with AMD. Will post back with my OC later. Buy Buy Buy

5 out of 5 eggsBest processor I have worked with

Pros: Works perfectly. Easy-to-OC Black Edition. 2.8GHz stock speed. Managed to unlock my fourth core. Haven't noticed any stuttering in CPU-intensive tasks.

Cons: I had a little bit of a hard time figuring out how to get it out of the box. It was really well put together. Not much of a con.

Other Thoughts: Used on Asus M4A785-M Motherboard. Runs flawlessly.
