System Benchmarks
Power Consumption
Power consumption was tested on the system as a whole with a wall meter connected to the OCZ 1250W power supply, while in a single MSI GTX 770 Lightning GPU configuration. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, which is suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.
While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.
The added power draw of the FX-9590 is quite clear, showing 350W for the full system during a heavy CPU load. However, the idle power draw of the CPU is similar to that of the FX-8150.
Windows 7 POST Time
Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows 7 starts loading. (We discount Windows loading as it is highly variable given Windows specific features.) These results are subject to human error, so please allow +/- 1 second in these results.
The FX-9590 afforded a shorter POST time than the FX-8150, although both are north of 16 seconds.
Rightmark Audio Analyzer 6.2.5
The premise behind Rightmark:AA is to test the input and output of the audio system to determine noise levels, range, harmonic distortion, stereo crosstalk and so forth. Rightmark:AA should indicate how well the sound system is built and isolated from electrical interference (either internally or externally). For this test we connect the Line Out to the Line In using a short six inch 3.5mm to 3.5mm high-quality jack, turn the OS speaker volume to 100%, and run the Rightmark default test suite at 192 kHz, 24-bit. The OS is tuned to 192 kHz/24-bit input and output, and the Line-In volume is adjusted until we have the best RMAA value in the mini-pretest. We look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.
USB Backup
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 240 GB OCZ Vertex3 SSD with a SATA 6 Gbps to USB 3.0 converter. Then we transfer a set size of files from the SSD to the USB drive using DiskBench, which monitors the time taken to transfer. The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the WinRAR test. In an update to pre-Z87 testing, we also run MaxCPU to load up one of the threads during the test which improves general performance up to 15% by causing all the internal pathways to run at full speed.
The increase in CPU speed of the FX-9590 gives a measured improvement in standard USB copy times – saving 4.3 seconds over the FX-8150 for USB 2.0 transfers. However using XFast USB eliminated that difference completely. For USB 3.0 transfers, using the Etron controller put a consistent advantage on the side of the FX-9590.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line. So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled. If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks. Having a bigger buffer and correctly implemented system drivers obviously helps in this regard. The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - less than 500 microseconds usually gets the green light, but the lower the better.
In a surprising twist, it would seem the FX-9590 has a disadvantage for DPC latency. I would have expected the faster processor to have the lower result, but one might speculate that the BIOS is tuned more for the mainstream processors such as the FX-8150. The chipset might also be geared more to the FX-8150 as it was the earlier generation compared to the FX-9590.

the fx series does need to go down in watts, which only comes in a die shrink from what i know. but the thing it has going for it are 8 cores, which intel doesn't even have in their consumer or enthusiast cpu's. u have to go xeon to find an intel 8 core cpu. my theory that amd is not updating the fx series or their chipsets is probably due to the backlash of the of fx series. i forgot when the the fx-8150 came out but it was negative. i don't think amd wants to have another repeat of that so amd is putting their cards back in the deck. they're softly announcing this and that about apu's... and hoping the marketing of apu will be enough to garner positive feedback. bring the image back. that is all it is, i think. what the hell is an apu, anyway? oh, it's the future. this is what amd wants ppl to know. but, we know that apu is not the future. it's just a stop gap for amd. it's just a fancy acronym.i don't think the low performance of amd fx cpu compared to an intel part is also solely amd's fault. i think software developers/coding can also be attributed to it. i mean, if you have this and that code built for intel chips since they're inside (i hate to say it) most of the pc's in the world, then of course, intel will have a lead from the get go. for example, windows 8 is suppose to be better for amd fx cpu's than windows 7. now dig deeper into how programs are run and make it so that an fx chip will shine as much as an intel chip, then we probably have a very well optimized program, which in the real world is probably a unicorn program. so, this unicorn program puts both amd and intel chips thru its paces, equally and optimally and fully. and i think that unless an intel chip has a specific function that makes it run faster (i forgot what it is), then an amd fx 8-core chip with its more logical, fully functional, real cores of 8 will probably be better than intels 4 cores with hyperhtreading. intel has patents for those specific, specialize tasks though and this is why intel is hard to beat and why amd loses to them.
this is why amd is waiting b/c 1)amd knows intel's roadmap and 2)they have apu's and consoles as stop gap 3) they'll return to the desktop performance cpu when the tide, the program/software/patents or whatever it is has leveled out so that amd can put out a competitive product that is truly innovative. and not just tick and tocks 4) the cpu fabs are probably too expensive right now for amd to jump in and do a die shrink (not sure tho; maybe intel has a hand in that too? idk)--like why is intel the only cpu company doing die shrinks every year and half? sounds weird to me. and it's closest competitor is just sitting back. weird right? anyway, im out of theories, i think.
oh, you'd think amd would just put 8 core kaveris without an igpu, right? but, no. i think amd is still not sure the performance gain with that will be enough to wipe out the negativity of the fx-8150 debacle. so, amd is just not doing it.
what do you guys think of my theories?

"but the thing it has going for it are 8 cores, which intel doesn't even have in their consumer or enthusiast cpu's."I stopped reading right there. If you think 8 cores in a 4 module FX CPU are comparable to 4 cores in Intel mainstream CPUs or 8 cores in Intel enthusiast CPUs, you should go back and read up on the architecture differences. The fact that an Intel 8 thread CPU (core i7 with 4 cores and HT) usually beats any FX CPU with 4 modules should be warning enough that you shouldn't draw any conclusions based on that.

Ive read up on bulldozer architecture. 4 modules with 2 logical and physical cores = 8 cores. Intels hyperthreading arent physical cores but software driven. so an OS sees an i7 with 8 cores even tho 4 of those cores are virtual. AMD has 8 physical/logical cores. Each module or 2 cores do have to share FpU, l2 cache (i think) and another thing. So, the cores are hampered by this but it doesnt take away the fact that there are 8 cores there. And i know its slow even though it has more cores than intel. But by refining it and better software optimization, i am wishing AMD to at least compete with intel enthusiast x99 chipset in the future with half the price. Why? Bc i cant afford intel. Simple as that.mapesdhs - Tuesday, August 12, 2014 - link
Sorry it's not an 8-core at all, not when it has to share resources split int vs. fp. Hence whythis very article shows again and again the older 4770K beating the 959 on threaded loads,
with 60% less power consumption. Convincing yourself that AMD's "8 cores" marketing has
any kind of sensible basis is as bad as believing MHz is an equally useful metric, or MIPS.
Intel's real, old, 6-core, the 3930K, utterly demolishes the 9590, for less power, etc. If you're
on a budget, buy a used 3930K, it'll leave AMD's chips in the dust, and there are plenty of
low cost X79 boards these days, especially on the used market (Gigabyte UD3 only cost me
55 UKP).

Noob, 2x ALU per unit DOES NOT equal 2 FULL CPU cores! The ONLY "edge" AMD has gained by this, frankly, AWFUL architecture, is in marketing, because they can somehow LEGALLY call each unit 2 CPU cores - when they do not function as such at all! In fact, HyperThreading provides better real world performance that doubling APU's when the architecture involved has much higher IPC as well as a DEDICATED minimum of 168 GB/s to L3 cache per core, at stock speeds!AMD calling a 4 unit CPU an 8 core machine is essentially the same as intel calling a 4 core i7 an 8 core CPU! HyperThreading is NOT software! read more about CPUs bro.

you said intel has no non xeon 8 core cpu's. But haswell-e will have 8 core/16 thread. I currently run an i7-980x gulftown x58 system and will be replacing it with 8 core haswell-e. video production speed should sky rocket.mapesdhs - Tuesday, August 12, 2014 - link
That depends on what you're doing, which app, where the bottlenecks reside, etc.If you've already oc'd your 980X then you're starting from a pretty good baseline,
so don't expect HW-E to be that much better (NB: I have a 990X, a couple of 3930Ks,
4820K, seveal 2700Ks, etc.)
What really will help for you is the newer I/O provision, ie. SATA3, PCI Express, M.2, etc.
The non-Intel SATA3 controllers on X58 boards were pretty awful, especially Marvell.
And of course you can at least double your max RAM, which might be holding you back
somewhat if you're a heavy AE user.
