AMD FX-9590 and FX-9370 Review: Socket AM3+ Platform's Swan-song
The FX-9000 CPUs require a special AM3+ mobo with a proper VRM circuit to provide sufficient power without overheating. You can not use a standard AM3+ mobo without overheating the VRM circuit and causing it to throttle the CPU frequency and performance.
Yes you might run a few benches but the VRM circuit will overheat and could easily fail if you use an AM3+ mobo that isn't specifically approved for the FX-9000 series CPUs.
The FX-9000 requires a top of the line HSF such as the Aegir SD128264 with a second fan, Noctua NH-D14, Phanteks PH-TC14PE or the Thermaltake Frio. If you're dumb enough to use water cooling you'd want a Swiftech 220 or better.
In addition socket AM3+ is EOL in Q1 of '15 but the FX name and discrete CPUs live on contrary to all the errors in this story.
The lowered price makes these attractive if you already have an FX-9000 approved AM3+ mobo and top 5 tower cooler. Otherwise it's a financial stretch for most folks. For those who don't understand these are just "halo" products to show that AMD's Vishera CPUs are very capable, which they are even when overclocked by the factory.
I use a 95W AMD FX8300. When overclocked to 5GHz, I am not seeing much increase in the power consumption at all. I have to say, objectively speaking, that intel has a very strong edge with the latest i5 and i7 series CPUs, out of the box. But not everyone uses the same hardware configuration. That's why we have some who are very knowledgeable enthusiasts who have experimented with a wide array of hardware configurations with many hours of testing with different settings. It takes alot more to convince someone like me so I have read so many reports and reviews over the past 15 years just to get as much data as possible when i make a decision to buy something. And finally, I bought my first FX CPU in October 2013.
One thing that I noticed about a good comparison with games and comparing FPS. When someone uses a high end video card setup, maybe Crossfire or SLI, it takes the load off the CPU. So all the FPS scores in this review are pointless. Because the video configration in this setup was lacking if you want to build a good high end gaming machine. Like I said, I have an FX8300 95W processor. I witnessed this CPU at work while running 2 video cards in Crossfire with the FX8300 overclocked to 5GHZ. The total system wattage only increased slightly and when you do the math the conclusion was the CPU never even exceeded 125W. Well, I was so impressed by this system's performance I had to get an FX8300. Not only was it doing well as far as power consumption but the i7 4700k system it was being compared to was running at stock clocks with the same crossfire setup and only 2 out of 7 games did the 4700k rival the FX8300 in FPS. The guy who was doing this test told me not to place any emphasis on the FPS test because he said any enthusiast who knows how to build a rig should know that the GPU takes the brunt. Now, he said he can squeeze more frames out of the 4700k by overclocking it. SO I wanted to see. In order to beat the FX8300, he was causing the 4700k to consume alot more power. And in the end what we had were 2 high end systems that performed near equal, and power consumption with both CPUs was pretty comparable. Any differences were not worth mentioning. So basically if you do not look at the WHOLE picture when configuring a system, or doing a review, you are only going to convince those who do not know that much
All enthusiasts who have broad knowledge of system hardware integration are keen on some important details when building a rig. It's said that if you want to equal the performance of the i7 4700k with the comparable FX CPU, you have to overclock the FX CPU about 600mhz over top of the intel CPUs current clock rate. When it comes to overclocking, AMD seems to have the edge. Because some people have taken FX8350 to 5.2Ghz or more while using commonly used high end cooling products. In order to get your i7 4700K within 600mhz of this overclock, it would need to go to at least 4.6 GHz. Well that about squeezes what most 4700K CPUs have in them because they are known for being limited overclockers. Intel insists on using paste for the transference of heat between IHS and the die. If you want to risk damaging your CPU, you can remove it and solder the heat shield to the die or be smart and pay an experienced person to do it for you. This will add another $100 to the cost of your CPU, give or take.
In fact, so many people selling i7 4700K CPUs on EBAY as "NEW OTHER" because of how inconsistent these processors are. Enthusiasts buy the 4700K new, try to overclock it only to find out they got weak cores that do not overclock well. Alot of 4700K CPUs can't even exceed 4.2GHz without massive heat problems and system lock ups. And that should also be something to consider if you want to build a high end system with a nice overclock. Some people have gone through 4 or 5 4700K CPUs just to get 1 that overclocks to 4.4 to 4.6 GHz. Honestly I may not even consider trying a second time if it did not work the first time. And I won't settle for a limited processor. Making such a statement that AMD is out of the high end PC market is such a narrow minded way of looking at things . If you think about how consistently well FX CPUs can be overclocked, many will consider it best to chance an FX CPU and get to 4.8 or 5GHz or even higher instead of risking the chance of getting one of the many 4700K Dudds that are out there.
I am in no way trying to compare the processors in the same way this review compared them. These things I am mentioning were all factors that were important to enthusiasts when deciding which platform was best and this is something that is equally important to me.
At the end of the day, nobody has to run an FX processor at clock rates so high to get performance that will be more than adequate to handle any game or program you throw at it. When someone wants to show one platform is better than the other, that is just is the agenda they have. If a system with a 4700k will give me 100 FPS while running a high end game, using total system wattage of 250W I am going to be happy. If I have to run my FX8300 at stock clocks or restrict my overclock some in order to keep my system wattage comparable, it will not make my system inferior. Even if my system only gave me 85 FPS in this scenario, I do not know one person who will complain with 85 FPS with a high end game running at a high resolution. You just cannot claim a benchmark makes a CPU better when so many other things can be done to make both platforms more competitive. And in the end, there will be several scenarios to make both winners in many tests. It's is the versatility that won my vote. Intel required too much effort and money to make it versatile for overclocking. Not to mention to risk of getting one of the Dudds.
So, keep the reviews coming, because there are still some "wanna be enthusiasts" that will be easily swayed by a benchmark. But once all are on board, and more and more programs are designed around multicore architecture, the benchmarks programs will have to follow suit and then we may see that an 8 core FX CPU was never worst than an Intel i7 CPU. Perhaps FX CPUs are ahead of their time. Real world performance has always been more than fast enough and even FX Quad core has managed to integrate with other good hardware with the end result being a system that can handle ANYTHING you throw at it. People try to make them seem like they are not even competitive and that is the mindset of those who are biased. Do not ever discount an AMD FX Series Processor. Instead, learn more about ways to take advantage of how versatile and powerful it really is. And never worry about getting a Dudd
