Pros: Overclocking

Cons: Performance overlap with prior generation

Okay, This processor gets a lot of hate from all sides due to the stigma surrounding the BullDozer architecture. I upgraded from an A64 X2 6000+, and it is much faster than my previous system. It feels faster than my old Phenom 9950 @ 3.2ghz by a good margin as well.

Games play nicely on it, mainly due to the ludicrous overclocking (4.8 Ghz). I have a 3DMark 2011 score of P5251 (GTX 470) with a physics score of 4581.

Skyrim runs smoothly with all settings manually set to Ultra.
Crysis 2 maintains about 30fps on DX11 ultra (V-Sync on, more than likely due to lack of videocard muscle)
Far Cry 2 holds at 60fps (V-Sync)

Haven't got to test with Rage or Metro 2033 yet, will update when I get them installed and tested.

Pros: Good price point, awesome overclocking upside

Cons: runs a little warm on the higher clocks but still able to get respectable numbers.

Performed as well as my phenom II 955 or better and certainly overclocked better. Its a fun processor if you can get it for the right price.

Pros: Cool at stock. Much OC headroom

Cons: Weak at stock frequency, stock cooler a joke

I have beat this CPU to death with testing, benching, tuning, and stressing. Well, not quite to death. It still works fine. It's actually the longest I've owned a single CPU model in a while now, going on 9 months.

Two years ago, when I built my Thuban rig with a 890FX motherboard I was delighted to see that it was also going to support AM3+ CPUs. Naysayers kept trolling on about how the AM3+ CPU pins wouldn't fit, and how it needed a black colored socket, lol. I have had about half a dozen Phenom II CPUs to play around with by this point, so I was anxious to try the latest offering. But I wasn't about to invest into the $300 FX-8150. Instead I picked up the nerfed $100 model known as the FX-4100.

I was obviously not expecting this $100 quad core to exceed performance of my $170 mighty Thuban. but this was something new. Something I had to play with.

The first thing I noticed was that it ran extremely cool at stock. So cool, that it threw up erroneous temperatures in Core Temp. I couldn't get accurate temperatures until I juiced it with some overclocks. Too bad at the stock frequency it was seriously lagging the minimum FPS in Dragon Age. I ran a few quick benches like the CPU physics test in 3dmark11, and the linx FLOPS test. Sadly it was performing not much better than my unlocked Sempron 130.

Overclock time. Right away it was handling my 2x4BG of DDR3-1600CL9 much better than my Phenom IIs could, taking it up to 1800MT/s at CL8.Bandwidth improved, but apparently L3 cache latency is much worse. This particular chip clocked stable up to 4200MHz on stock voltage, and was still running cool, not breaking 35C with a Hyper 212+. With a healthy voltage bump I settled on 4500MHz for a 24/7 clock, since it was still cool at that speed, barely pushing 40C under stress. To hit 5000MHz I needed to use a much higher voltage to remain stable, and I was even able to stabilize 5125MHz, but stress temperatures at this point were 65C. I was able to push my CPU-NB to 3000MHz for my 24/7 clocks with a good voltage bump. I am currently running my RAM at DDR3-2000 CL8.

While performance at stock speed was downright sucky, performance improved quite a bit once things were tuned up. It's just about as fast as my old Phenom II 955 now, which I had paid about $160 for a few years back. So ok, meh I guess, lol. What is more interesting is that performance scaled even better when I tested around 5GHz. If AMD can patch up the leakage issues and deliver the next version of this chip at those clocks, they could have a real winner, much like the original Phenom progressed to the beloved Phenom II rev C3 and E0 steppings.

I'm giving it a 3.5 score. At the time, it cost about the same as the Phenom II 960T, a superior processor. It is also slower than intel chips at the same price when at stock speeds. This chip does have a lot of headroom though, and does improve performance when overclocked. At 4.5GHz, it was enough to enjoy my games at the highest settings without the minimum FPS falling off a cliff. But at stock speeds, it isn't any faster than my Athlon II x4s. You aren't going to get much use out of the stock cooler that came with this chip. Something like a Hyper TX3 would be plenty to overclock this though.

Pros: Inexpensive, 4 cores, Easy overclocking

Cons: None

I had placed a few of these in gaming builds earlier in the year. They seemed to perform very well in those gaming rigs, so I decided to replace my Phenom II x 4 and see how the Bulldozer fared in my personal rig. I have been using it for several months now, and I have to say I am quite pleased. Initially, at stock temps and with the stock cooler, the chip idled at 9-11c with a load temp of 30c (stock clocks 3.6-3.8GHz Turbo). Eventually I got around to placing it under water and now enjoy a 4.8GHz OC that is P95 stable (overnight) and the chip has yet to give me any issues. At this OC and under water, the chip now idles at 19c and ran 44c max during P95! This is one cool little chip - literally! My Phenom chip ran hotter than that at stock speeds (due in large part to the 125W factor). I have yet to challenge the depth of this chips overclock ability. I briefly had it clocked over 5GHz but P95 kept shutting down on one core. These clocks were achieved just by increasing the multiplier. I think with more adjustments - maybe with the voltage - I could undoubtedly get a solid stable 5GHz from this chip. I play Diablo 3, SWTOR, and a number of Steam games - all of which run flawlessly using this chip. I would strongly suggest trying this CPU for any new gaming build. Especially if you are on a tight budget - this is a no-brainer! thumbsupsmiley.png

Pros: Fast ,Cheap , Plays games at Max

Cons: Nothing

Love this Processor , Massive improvement from my Old Pentium E2160 For only £84. Plays games at max , fast and cheap. Does exactly what i need it to do ! smile.gif

Pros: speed/stability

Cons: none so far

simply... it is a inexpensive, very easy to overclock cpu. i easily overclocked mine to 4.5Ghz without extremely high temps. in my opinion, you cant buy a better performance cpu than this. intel and amd have there pros and cons but you just cant beat the price and speed of this.thumb.gif

Pros: Price for performance, OC'ing if needed

Cons: the feeling of wanting more..?

For me this upgrade was pretty big. I went from a Phenom II X3 720 (rushed buy do to burning up old CPU) stock to the 4100, which I plan to OC today when my cooling arrives. Paired with the 990fx seems to be a great matchup. I dont have any marked numbers to post as if I was solidifying my ranking but again AMD comes through in the price/performance platform. A friend of mine got the 6100 and we will both be OC'ing so hopefully I can put up some similar numbers.

Pros: Ran VERY cool(i think)

Cons: very slow..terrible ipc

Ok..so..i purchased an fx4100..because..i'd been waiting for bulldozer all year and wanted to stick something new in the $200 990fx Sabertooth mobo i have.I ordered it from Microcenter on release day..it arrived a week later kookoo.gif .OK..so I'm going to post what documentation i have of it..pics..short explanation..etc..In the end..i traded it for a 64gb Crucial M4.
