AMD’s 5 GHz Turbo CPU in Retail: The FX-9590 and ASRock 990FX Extreme9 Review
by Ian Cutress on August 9, 2014 8:00 AM ESTThe AMD FX-9590
The analysis in this review shows that even a year after the OEM release of the FX-9590, and almost two years from the architecture coming to market it remains AMD’s performance part. If power consumption is not a concern, as a CPU compute and an AMD gaming CPU (especially when considering SLI) the FX-9590 is the best choice at stock speeds. On that basis alone, it makes sense that AMD should actually release it as a retail part, assuming they have enough stock. One might argue that a user could buy an FX-8350 and overclock, but if our sample CPUs were anything to go by, a user needs a fair bit of luck. The FX-9590 guarantees a 5.0 GHz turbo with a warranty.
With the retail release of the CPU, that warranty might be based on using the water cooling provided for the lifetime of the CPU. One might argue that AMD had trouble finding enough dies that could reach the frequencies and voltages for the FX-9590, and hence the delay combined with selling the SKU in select markets only.
The FX-9590 is the same Piledriver architecture as the FX-8350, which in turn was used in the A10-5800K/A10-6800K APUs, codename ‘Trinity’ and ‘Richland’ respectively. Since then, AMD has launched the Steamroller architecture modifications in the form of Kaveri APUs. The difference between a PIledriver APU and a similar frequency Steamroller APU, if we put aside the move from 32nm SOI to 28nm SHP, is around 10% for CPU performance. If that was shifted into a four-module, eight-thread CPU, it would surely be AMD’s performance part. The issue here is that AMD has almost discarded the high CPU performance arena in favor of integrated graphics. From Trinity to Kaveri, the IGP inside those APUs has improved considerably, indicating where AMD is investing its research dollars.
AMD clearly still cares about the performance market, otherwise this retail FX-9590 with water cooling would have never been pushed through to retailers. The high power consumption, the lack of a modern chipset, and the comparison to Intel CPUs in single threaded benchmarks are the main barriers to adoption. If AMD is to return to the performance market, the power consumption has to be comparable to Intel, or if it is slightly higher, the chipset has to offer something Intel cannot. Any suggestions for what that feature should be should be submitted on a postcard/in the comments.
ASRock 990FX Extreme9 Conclusion
One of the big issues surrounding AMD motherboards is their price sensitive nature. With an Intel based product, a $250-$400 motherboard is common enough to signify the expense in research or extra features. Because the AMD ecosystem, even in the high performance segment, is a cost sensitive market there is little room to move. For example, this year sees the first overclocking based motherboard for AMD APUs since the AM3+ era. So at $170, the Extreme9 could arguably be described as ‘limited’ compared to Intel standards.
The motherboard itself has specified support for 220W CPUs, something other motherboards either fail to mention or advise against completely. The native SATA 6 Gbps ports were ahead of Intel at the time, plus ASRock adds in another SATA 6 Gbps controller for good measure.
The eight USB 3.0 ports makes the Extreme9 have more USB 3.0 ports than almost every other 990FX/AM3+ motherboard ever released. This is combined with plenty of legacy support, such as separate PS/2 connectors, a PCI slot, an IEEE1394 port and an IEEE1394 header. The Intel NIC is paired with a Realtek ALC898 codec, with the PCIe layout aimed at 3-way GPU users for both Crossfire and SLI.
Aside from an updated chipset, if we were building a high-end AM3+ motherboard in 2014, I would insist on WiFi support and an upgraded audio codec to the ALC1150 at the minimum. We cannot get around the lack of PCIe 3.0 support, although moving the CPU modules from Piledriver to Steamroller along with the IO support might help with that. If we are being greedy with what we would like, I would add in M.2 support as well.
There is plenty to speculate if AMD had kept updating their high-end performance CPU line, even if the socket was not updated. As it stands, users who want SLI either look back to 990FX or invest in Intel. Users who want high multithreaded CPU performance either look back to 990FX or invest in Intel. Users who do not want processor graphics either look back to 990FX, buy an APU with the graphics disabled, or invest in Intel. AMD clearly does care about the performance market, or at least someone senior in the company does.

Umm you KNOW that even stock clocked that the i7-3770K is better and faster in EVERY way, than the 9590 OCed to the max, right?You also know that while you saved, literally, a couple bucks on BUYING your hardware - you are going to spend, comparatively, hundreds of dollars more running it for even 2 years!
Oh then there is the effect that the HUGE power draw has on components - mobos, PSUs, video cards, RAM - because ALL of it gets effected by the insane heat - and certainly ALL of it will be effected if you short your PSU!
And i7-3770K at stock frequencies out performing this POS FX 9590 - is NOT synthetic! That is real world PROVEN speed! NTM, you can EASILY hit 4.7 GHz on any SandyBridge chip - which will not only yield MUCH better performance, but will suck less power and be more reliable as well! And you aren't even going to have to spend that much to buy a good Z77 board and an i5/i7 2500k/2600k (ASRock Z77 Extreme 4 runs right around $100 right now, and is FAR from any budget board, and in fact has more features than ANY FX board that could run this 220W POS!)
So pat yourself on the back, you saved a few bucks on hardware! BUT you completely sacrificed ALL performance, and ANY reasonable upgradability! Also, you will end up paying FAR more than you saved in power costs! (I am sure your power company will thank you for choosing an AMD space heater for a CPU!)
Well on that note, you may save a few bucks on heating, given you live somewhere that gets colder than 50 degrees (Fahrenheit) at some point in the year anyway.

LMAO! Cult - you are such an AMD fanboy NOOB! It is not a cult when PERFORMANCE and EFFICIENCY are the deciding factors!And again, you saved a few bucks when buying your already outdated POS AMD space heater - just wait til that power bill comes!
And if you seriously cannot afford an i5/i7 K processor, even a Sandy or Ivy Bridge, and a Z77 or newer chipset, what the hell good is faster ram and an SSD going to do you? None, unless your workload is entirely composed of highly multi threaded compression/encoding etc.
Have fun with your 220W space heater that has to compete against i3 CPUS! LMFAO!

Just another instance of AMD CHUGGING power and crapping performance! Combine this FLOP of a chip (220 W TDP - sweet Jesus! At STOCK) with an R9 290X (300 W TDP, again holy sh*t!) and you are up to over 500 watts TDP!Compare this to an Intel i7-5930K (140 W TDP) paired with a GTX 970 (148 W TDP) and you are ONLY at 288!
Not ONLY that, but the Intel is faster BY FAR at stock speeds, as well the GTX 970, while costing only $30 more - provides ~10%-25% frame rates in basically EVERY benchmark!
I just feel sad for AMD anymore... I am guessing they are too busy with owning ATI and TRYING to compete with SandyBridge and newer Intel products (My i7-2600K beats this FX chip at STOCK speeds in most benchmarks - and basically ALL gaming benchmarks! And that is not even mentioning that the 2600K easily hits 4.4 GHz on any decent mobo/chipset! Then there is the fact that the 2600K is THREE years old, only 95 W TDP - which will NEVER go above 125 even at the 4.7 GHz/102.3 Bclock OC I run!)
AMD should have realized this Chip's Architecture was DOA with the first PileDriver CPUs falling FAR behind the Phenom 2 1100Ts! And even now the 1100Ts generally have better gaming performance!
The REAL question is, WHY? Why have they not dropped this design and brought us a new one? I mean they could try it with limited releases to test it at VERY least, but I hear no word whatsoever about AMD being anywhere close to a completely new chip design!
I was a staunch "AMD Fan-boy" back in the Pentium 4/Athlon XP days! They WERE far better! Also back then ATI could actually compete in gaming!
Now? AMD is only good for budget gaming builds - parts like this FX chip are just about pointless - apart from people who already own a good socket AM3+ mobo. But buying this chip for a breand new build? That would be a HORRIBLE idea! Only the biggest fans of AMD would waste such money and power..
And AMD VideoCards - yes they have better compute performance - so yeah, if you are still GPU mining new Crypto's (Like VertCoin's Lyra2RE Algorithm) - buy an AMD GPU, but 2 or 3 if that is your goal! But even then, apparently the HD 7000 series are STILL the best miners, as they do not consume INSANE amounts of power and do NOT run at a "SAFE 95 deg C" (AMD's quote on R9 290X operating temp!) So, whereas Nvidia and Intel move forward with less power consumption, cooler temps, and better performance where it matters, it REALLY seems AMD is taking steps backwards!

So this motherboard suits basically for those who will overclock the processor, graphics and RAM.Honestly, I don't know why would any purchase a AM3+-based motherboard since we have to wait for eight months only to get some AMD Zen processors that are (at least on paper) much better than FX. So, I am thinking about the new motherboard and a new processor. Since Doom 4 will come out next year, will have to get something better than my current configuration, that is based on the ASRock 970 R2.0 (BTW, this is a pretty good MB, have bought it here - http://hardware.nl/asrock/970-extreme3r20.html almost two years ago and happy with it)

Do not buy from Asrock. You will be on your own.
I bought an Extreme9 just before Christmas 2015. Went to raid my 2 Crucial 512gb SSDs and computer would not see them. Called Asrock tech and they told me certain makes of SSDs are not compatible with Extreme9 boards. I explained that SSDs were much older and Asrock board should be backwards compatable. He gave me a short list of drives that were compatible and said I'd have to buy new drives. Asrock took no responsibility and were in no way helpful.

Where's the described M.2 Slot? Ctrl+F'ing the manual for M.2 doesn't shows up any point.
