first to review
dont be prejudiced by negative reviews


With negative reviews floating all around the internet about the FX Bulldozer one may think this is trash and a complete waste of money which is totally not true .

The performance hiccup materializes beacause the scheduler in windows 7 is not optimized to distribute load across modules
and microsoft has already released an incomplete patch to overcome this situation and will surely be completely fixed in the coming months .

Even in the current situation , the processor performs no less than the intel sandy bridge processors and which makes this a great eight core processor with the required fixes expected shortly .

8150 or the 8120 FX ?

If you plan to buy a Bulldozer 8 core buy the 8120 over the 8150 because the 8150 is just a binned processor with a higher tested core frequency . With the Rs 2000 odd saved you can buy a good after market cooler like the cooler master hyper 212 plus to overclock it to achieve similar performance of 8150 and even go beyond with liquid coolers like the corsair h60

The 8150 and 8120 processors are collectors edition chips and hence come in a nice TIN BOX and like all FX series processors come with their multiplier unlocked to achieve easy overclocking .

To achieve best performance you can buy gigabyte ud3 or ud7 990fx chipset motherboards or asus m5 990 fx chipset motherboard


If your sole purpose is to game then disable some cores in the bios which lets u overclock the remaining good ones even higher and also save power.BF3 runs smoothly at 75 to 80 fps with 6950 on a 990fx chipset motherboard .

If you are still a little shaky then wait for the next revision of these processors expected in first quarter of 2012 ...

enjoy the amd fx multi core performance and remember there is nothing wrong with the hardware only that software has to be optimized to take advantage of the new module based architecture ...

Internet reviews HATE AMD for some reason..

I have been using the FX 8120 for quite a while. Initially i was apprehensive to go for an AMD build or stick to the costlier Intel build. I decided to go for the FX build.

I had checked reviews and benchmark test results on several review websites.. they scared me.. it seemed that the FX series was hardly performing better than the older PHENOM X4s!! yet I took a gamble and built my system.

My mobo isnt powerful.. BUT, the 8 cores are really showing off their potential.. I am a freelance graphics artist and video editor. I am running aftereffects, PS and other intense apps without the CPU breaking a sweat.

My only problem is that the CPU overheats after 4 hrs long video rendering times.. but, i did expect that and it is also nothing that an after market cpu cooler cant fix :)

Real bravo to AMD for a fine job!

now, if only the pesky, intel-inclined review sites can stop posting biased reviews for AMD!

@Varun water cooling kit only for fx8150 with cardboard packaging ... tin box does not have water cooling

The water cooling system is only available on their flagship processor the 8150 which comes in a normal cardboard packaging and not with the one which comes in a tin box

Flipkart only has the tin box edition which is the collectors edition and comes with a traditional heatsink and fan

The water cooling system for the FX Chips is manufactured by Asetek.
Asetek were one of the first companies to offer closed loop water coolers and are also the original manufacturer behind popular water cooling kits like the Corsair H50 and H70 and the Antec Kuhler 620 and 920

But anyways you can always buy this and add a corsair h50 water cooling which is cheap and a great performer especially if you are overclocking and you should without any worries

a decent all rounder...along with being future safe!!

its very decent processor which will not disappoint any one in any field. Windows 7 index rating for this is 7.5 so you can imagine how powerful it is along with this the performance to price ratio is also quite high. till date the intense games or softwares use at most 4 cores so in some benchmark results shows that it lags behind. but it beats its competitor when there is any software or games which use more no. of cores.

without even overclocking it shows a great and satisfying performance.

the only problem is with the stock fan and heat sink. they are really useless. it reaches around 65C when playing games in ultra resolution graphics and at ideal its around 45C.Amd has said that max temp should be 61-62C.Buying a liq cooled or some good cpu heat sink will definitely do.

Why people and benchmark say fx 8120 is slower than Intel i3,i5,i7 technology?

(Sorry for bad english)
According to benchmark report AMD FX 8120 is slower than Intel i5 or i7 processor (In most cases).But people forgot that 3.1 ghz 8 core not equal to (3.1×8=24.8) 24.8 ghz.The eight core means this processor run 8 program at 3.1 ghz speed in same time.But,in present time most program and game not compatible to take advantage of a 8 core cpu.In benchmark time when same program running on fx 8120,i5 2500 k and i7 2600 k the fx 8120 used only 45%,the i5 2500 k used 100% and i7 used 90%.The i5 and i7 architecture is small better than fx 8120 so,i5 and i7 is small time faster than fx 8120.But in case of multi tasking the fx 8120 is more better than for its 8 core technology.
When future program and game compatible with 8 core technology,fx 8120 is faster and better than all i3,i5 and i7 technology.
And not forgot the feature of overclocking technology of fx 8120.In normal heatsink and fan system the processor goes upto 4 ghz (Without overheating).And with liquid cooler system its speed goes upto 5.5 ghz.
For those I said amd fx 8120 is also better than intel i3,i5 or i7 technology.
So go ahead with AMD technology in cheaper price with Best Performance.
The AMD FX 8120 is better in performance than i3,i5 and i7 (In case of liquid cooling system overclocking).And it is also good for multi tasking (Normaly,for its 8 core technology).

awesome processer i was in a tight budget dont know what 2 buy then i say many negative reviews about it
i bought it because my friend said to buy
actually iam intel fan guy

1.awesome processor
2.flawless multitasking
3.if u are a gamer it is the best choice in budget
4.inbuilt graphics which is better than intel hd graphics
5.good processor for heavy gamers and vedio editors
6.worth for its price
7.easy to overclock (but needs a very good cooler)
8.overclocking goes till 5.8 ghz in my pc

1.needs a very good cooler for overclocking and better perfomance
2.not an 8 core perfomance just gives a 6 core perfomance
3.does not works good if u r a heavy gamer and playing for more than 3 hrs up ur electricity and more bill end of the month

best processor for your moneys worth.

i wont compare it with an i5 or i7 or such. i bought it for the specs it mentions and it does deliver!! it also gets a rating of 7.5 (out of 7.9) in windows 7.
you have all the reasons to consider this cpu.... worth every penny u pay.

World class Performance.....

Earlier I have i3+AMD 7770 (Primary Graphics)+Nvidia 250 GTX (As Physx card) . I was thinking it is enough for gaming but when I Played BF3 really I was disappointed with performance..even in medium setting.

Then I decided to replace with i7 or i5 but price was too high but when my friend told me about AMD fx processors then I finally decided to replace whole machine with AMD even I saw a lot of rumors and bad blog about AMD but I know all was wrong because I was already used AMD 7 years back which has beat PIII in same line.

Now I have AMD fx 8120+AMD 7770 Graphics+ Low-end asus 760 motherboard. When I played, found, BF3 is now working like any think, So smooth in ultra setting..same thing with FC3 and NFS run in ultra. I am telling you guys take it and do not believe on rumors about AMD...You will get world class performance in cheap price..
