5 out of 5 eggsGreat Workstation Chip

Pros: Low Cost. Small power draw. works well

Cons: a few generations old.

Other Thoughts: This chip makes for a great workstation chip. I am running it on an AM1 ASUS board with 4 gigs of ram. 64bit Windows 7 Runs flawlessly with Chrome, Microsoft Office, and Microsoft SBA, which are used on a daily basis. computer is fast, stays cool, and best of all, the entire cost of the build was about $100 (not including a case). you cant ask for much more than that. happy me, happy employee, happy boss.

5 out of 5 eggsAwesome little chip.

Pros: I got this on sale for $27.99. This is a great value even with the prices going up to $36. For a dedicated use, this cpu will do great.

Cons: When you install the heatsink you'll see that the actual metal that makes contact with the heat plate of the chip is not big enough to cover the whole thing. And the compound is spread to the size of a quarter even though the chip is bigger.

So get a separate CPU cooler.

Other Thoughts: I just finished installing Arch Linux on my build with this CPU, and 4 GB of RAM and a 500GB laptop hard drive I had lying around.

I'm running AFP (Apple File Sharing), SMB (Windows File Sharing), Avahi (Network Discovery), SSH. Normally I use 27MB of RAM.

I tested Plex running on my Note 3, iPad Mini 2, and Web Interface running on my MacBook Pro 13" Retina.

ALL running at the SAME time. All 3 devices playing (2) 720p mkv, (1) YIFY mkv. The poor thing had all 4 cores peaking at 96% (AVG 60%), but it did it without a hitch with a peak of 347MB of RAM

Admittedly I'm using it with a super low footprint OS, but I used some live CD USB's of Linux distros as well and ran fine.

Windows 8/10 for sure will run great, those guys run great on low end parts now (with 4GB of RAM minimum).

5 out of 5 eggsGreat little low-power APU

Pros: Cheap! (For a quad-core). I got three of these APUs for a Jackson each from NeweggFlash on a special deal.

Overclockable! I've built two rigs with these so far, one with an Asus AM1M-A with BIOS 1201, and one with an ASRock AM1B-ITX with BIOS 1.60 (Love that Internet BIOS update feature!). Both rigs overclocked to 125 BCLK (1.625Ghz), using a SATA6G SSD connected to the AMD SATA controller in AHCI mode. Using 4GB Gskill DDR3-1600 RAM, overclocked to 1666.

Cons: I also cut myself putting the heatsink mounting pins into the heatsink. It required quite a bit of force, and my large fingers glanced off the sharp aluminum fins on the heatsink when it finally pushed through, giving me a small cut. Surely, they could have come up with a safer heatsink mounting mechanism. I rate the AM1 stock heatsink lower than both the S775 and AM2/AM3/FM2 heatsink mounting mechanism.

Other Thoughts: These seem a little sluggish without the overclock. (Stock speed is 1.3Ghz) Look up this APU on cpubenchmark dot net , compare the single-threaded score to other popular CPUs, like the older E5200, and the newer G3258. You'll find that it's quite a bit lower. But for the price, and low power consumption, it's worth it.

5 out of 5 eggsGood Deal, Impressive Low Cost APU

Pros: Surprisingly powerful for only 25 watts and 1.3Ghz

Cons: Only supports single channel memory config ='( I bought 2 x 2GB sticks thinkinG iwas going to have 4GB of dual channel RAM, but instead its 4GB single channel due to lack of dual channel feature in memory controller on the APU.

5 out of 5 eggsBargain Build - Plays Lightweight Games OK

Pros: Impressed with what this APU can run at just 25 watts and 1.3Ghz. It also does quite well with multitasking. Heatsink came with 1 of 2 locking pins missing. Contacted AMD directly and they shipped me a new heatsink with both pins 2nd day air express. Thanks AMD in A+ customer service. I only expected the 1 pin that I was missing and they shipped me a whole new heatsink complete with pins. Saving the original heatsink for years down the road when this ones fan fails and I can swap heatsinks and pins to put the other one in its place =) I built this system with the Gigabyte mATX motherboard.

Cons: Only Single Channel Memory only by design.... found this out after I bought the 2 x 2GB RAM sticks. I should have just bought 1 x 4GB stick. I bought 2 sticks thinking dual-channel memory config in mind for build, but read later that the Kabini doesnt have dual channel support, so its single channel only.

Other Thoughts: Plays Hearthstone perfectly fine. World of Warcraft ran better after I installed a PCIE video card since the HD8250 is kind of weak. Had to run wow on low settings. Without video card just on APU's integrated GPU it streamed netflix and other content flawlessly. No stutter or long load times etc. I am impressed with it as it is. But for gaming, I would only run lightweight games or lower the video settings to boost performance as I have. Flash games on FB run flawless as well on just integrated video.

5 out of 5 eggsWonderful Processor

Pros: The reason I gave it 5 eggs is because I knew what I was paying for. The processor was $30 and free shipping. I was aware the speed at which it can processes applications: 1.3 GHz. It was purchased for my grandmother who only uses applications such as YouTube, banking, and Microsoft Word.

Cons: I would highly recommend against purchasing this product if you plan on working with any video over 720p. The on-board GPU in conjunction with the operating frequency of the CPU just can't handle it. It's a quad-core, however it is a lower end quad-core. It can handle multiple processes at once, but like I said I wouldn't recommend video such as 1080p.

Other Thoughts: I completely understand this is a budget CPU and as such it won't process many applications as fast as an Intel Core i3, i5, or i7 (obviously). I can almost guarantee with at least a 1.6 GHz - 2.0 GHz processing frequency, this would handle it no problem. If that's what you're aiming for, spend an extra $5 on the Athlon 5150 (was $15 more at the time of my purchase. Grandmother was looking for the least expensive combo possible as she makes very little money).

Best bang for the buck in terms of basic processing, you ask? Simple answer; yes.

4 out of 5 eggsNice for light work

Pros: Low cost. Runs web browser, email and office applications smoothly. Installed several Linux distribution with only one hiccup, see cons.

Cons: Does not wake from sleep in Linux on two different motherboards. Tried Mint Mate and XFCE, also PCLOS lxde and mate. Everything else worked. Not sure if having only 2Gb of RAM was the problem, don't see why that should cause problems since it uses less than 400 MB at idle.

5 out of 5 eggsLooking for an objective review? Read on...

Pros: - Low cost, CPU + Motherboard = $76.14.

- Allows for small form factor.

- Low power consumption.

- Power efficient, Quad core on 25W TDP.

- Solid performance on everyday applications and non demanding tasks.

- No need for discrete graphics.

- Low noise level, Inaudible fan.

- Can play some games (not it's intended use).

Cons: - Only 1.3 ghz of CPU clockspeed.

- Only 450 mhz of GPU Clockspeed.

- Can't play 1080p videos smoothly.

- Games are playable mostly on very low settings (Example: World of Tanks on 1440x900 resolution with low settings @ 30 fps).

- Push pin design on the fan/heatsink mounts, some will like it, some will hate it, but AMD fans will definitely hate it for life.

Other Thoughts: AMD Kabini was created to satisfy a very specific market, which consists mainly of consumers demanding for an upgradable and affordable platform. People living in countries with a very low average income will benefit of this. Now, why do I mention this?

Because I know many of you are considering the AM1 platform to use it as an HTPC to play 1080p videos and play games occasionally. For this, you might want to consider another platform. Something like the A-Series will do that job better. Videos @ 720p will play smoothly but stutters at 1080p. Games are playable only if you are willing to sacrifice quality over performance. You can try boosting the performance a bit with a faster memory module, but is it really worth it?

Now, are we expecting people living in countries that can barely afford 1 mpbs ADSL internet to be streaming 720p? much less 1080? Or play demanding games online? The answer is quite obvious, and again... Kabini was not made for that. This platform does offer a solid performance for everyday computing. If you are building a computer for a senior, for your kids or you just want to use it for text editing, web browsing etc. this will do the job.

One thing I really hated was the push pin design for the heatsink mounts. I have always hated them on my Intel builds and this one is not an exception. Check out the instruction booklet on how to install this, even though you have an idea of how this work; I almost broke one of the legs. The fan is very small, and it is enough to cool this little processor. Another advantage of having a fan so small is that you might be able to fit the motherboard in a very small mini-itx case, such as the M350. Now to the noise level.... what noise?

Now to the guy who said that the heatsink was so poorly designed that he cut himself trying to install it. Troll somewhere else.

All in all, I am pleased with my purchase. Some may suggest you to go for the Athlon variants, but if you look at some benchmarks, the performance gain by going for the next Athlon is not too much. If you are on a very tight budget, or just want to build a computer to cover the basics this is for you. Anything beyond that, look somewhere else.

4 out of 5 eggsIts ok

Pros: Only 25W TDP, low temps ,Quad core, onboard decent graphics, can even do 4k rez video.
We use this in our work PC. Its a little slugish for my standards even with an SSD. But hey for less then 40 bucks what more do you want.

Cons: Just a little slugish thats all, but its fine for surfing, email,word processing machine.

Other Thoughts: Semprons are the budget line of AMD and thats why this is a little slugish but hey its under 40$ and can do 4k rez video.
