AMD FX-9590chat_bubble_outlineFrom real comments

The most repeated complaint is that the FX-9590 runs so hot it functions as a room heater, especially in winter, and requires serious liquid cooling to remain stable. Several users specifically joked about it heating an entire room.

@riusu8672

I never was able to keep this bad boi cool. I recall being gifted an h80i by one of my best friends and i could not get her past 4.7ghz sadly I was not an intelligent as i am with lowering voltages. I had to disable to boost to keep it from trying to go past 4.7 also as someone else mentioned indeed it was a great heater lol I still have my fx 9590 and its asrock motherboard and ram set, i have used it as a back up when my main pc had some issues with past motherboards.launch

I remember these. Fuck that. The power draw of these cpus made me skip the entire generation. Went from AMD Phenon II X6 to Ryzen but that was a 95 to 65 watt drop. Those 95XX's where known to be space heaaters in your room. \n\nFun chips thou! 👍Everyone that had one loved it, you would get one that OC the shit out of it, i mean anywhere from 25-30%! But not at those wattages. Your boy say how much juice those muthafuckas where suckin down and was like 💀💀\n\nI'm good on this generation.launch

That cpu paired with a R9 295x2 would make for a nice home heater in the winter :)launch

Many users benchmarked a manually overclocked FX-8350 against a stock FX-9590 and found the cheaper chip matched or beat it, arguing the 9590 was just a marketing-driven factory overclock not worth the premium.

@jotabe1984

no point in using an Fx9590 in any case whatsoever...\n\nan Fx8350/70 might be a lot more reasonable... you get almost the same performance for 1/2 the power consumption.\n\nthat being said, in my old rig (fx8350 w/Asus saber 990fx mobo + 2x8gb Kingston HyperX Fury 1866) when y switched the GPU from an Rx 570 4gb to an Rx 580 4gb i saw almost no real gain in most games, proof that the CPU was already at it's peak.\n\nThen i switched PC but retained the Rx 580 4gb, that was paired with an R5 1600 w/32gb DDR4 3200mhz. MAN the GPU gained 10 to 15% in performance in most tittles (true, many of these being Dx11 \"arcade\" games like War Thunder or World of Tanks) and that gain came just from the power of the Ryzen.\n\nNowadays R5 1600/1600af/2600 can be purchades very very cheap, A320/B350 motherboard are extremely cheap... you can build an AM4 platform with 32gb of Ram + at least 1 nvme SSD (at gen3 speeds but without problem and way faster than SATA3) + SATA SSD on a tight budget, looking for used parts... and you'll still retain the upgrade path of going Ryzen 5000 series later on.\n\nshure, AM4 is a \"past thing\" but still very valid for the present and for a couple years to come... AM3+ is a legacy platform that can't be called gamer in 2025. and i say it after using an Fx8350 from 2016 to early 2024, so i do love the Fx series that did served me well... but it is time to let go the Bulldozer familylaunch

@jotabe1984

man...\n\nAll Fx83xx series are the exact same CPU... they have only different clocks due to sillicon lotery/Stability test result during quality control.\n\nFx9590 was in essence the same CPU as the Fx8350. The fact that you get lesser results with a CPU clocked higher only talks about you messing the OC configuration. Nevertheless it is not some big of an issue... the fact is that most users wouldn't overclock their Fx8350 anyway since they coulnd't to it safely on cheap mid-range 970 boards with barely enough VRM to feed the 125w CPU.\n\nand for the high end users... an Fx9590 (that was nothing else than a factory-overclocked Fx8350) was pointless anyway since they could get about the same results of a regular Fx8350. 100 to 200mhz wasn't going to make such a big difference.\n\nAnyway. The Fx 83xx cores were a really bashed mainstream CPU lineup. Nevertheless they are still decent 13 years after release. Which is insanely impressivelaunch

It shouldn't have disappointed anyone. All of the sources at the time made it clear that the 9370 and 9590 were just factory overclocks of the same Piledriver 8-cores like the 8350. Based on some of your benchmarks, it looks like they toyed with the microcode on these parts to keep them stable at high clocks. That's the only reason they should lose to an 8350 at 4.8.\n\nI just ran my 8350 at 4.85 GHz and called it a day. I recognized the 9590 as just AMD marketing wanting to sell the first-ever 5 GHz processor.launch

@StaelTek

i will NEVER buy an FX-9000 chip. its basically an factory overclocked FX-8350 with a huge pricetag.\nhere in denmark the 9370 costs as much as an i5 4690K. the FX-9590 costs more than the i7 4790K. that overprice imo. that you can buy an 8350 and overclock it to an 9370/9590 with up to 50% off.launch

Reports include VRM throttling under sustained load, one chip's cores progressively dying until it became unusable, and general instability at stock settings without careful tuning and adequate motherboard power delivery.

@nicolasbertoncello-ys7ul

I got a 9590 back in 2015, i used it till summer 2020, when i swapped with a friend of mine i7 4790, i had so much issue with the 9590, it suddenly started diying a year later the purchase, i also got the same motherboard u used for testing the ROG Crosshair V formula Z, it was the only thing that saved that nuclear reactor from exploding, i had over the year as the cpu was continually diying, manually disable cpu cores so that it was slower but stable, until it became a dual core cpu… rest in peace dear friendlaunch

@danielwillmott1163

Yeap I have theee of them upgraded from 8350 …. Your power vrm can throttle it if it gets too hot also the cpu must be cold or it throttles down way before it gets unreliable both these issues must be resolved first before you see it being faster than the 8350 in most stuff I did notice it was faster even over locked it once well one of them the other two wouldn’t go any higher …. My daily. Is still a 9590 with windows 11 and 32gb ram 6700xt and 8.5gb off nvme ssd (4x980pro and 970pro) with a nvme pciexpress card the 4x980 is in raid 0 and with hp omen thread optimiser its fantastic !!!! ❤ you have to use hp thread optimiser on this gpu for modern games or it stutters bad I believe the problem is 4 cores are full cores and the other 4 don’t age good floating point unit either way it’s much better with the tread optimiser I don’t need to upgrade it yet as the new gpu gave it much more life it’s the highest scoreing pc on 3d mark with 6700xt and fx9590 well was when overclocked last time I checked 5 months agolaunch

@TheDarkWizard

I've owned this processer gave the PC to my brother, the info you have listed is kind of wrong its an 8 core processer but what you didn't realize its 4 core plus 4 logical processors. It is actually an 4 Core CPU with 4 Logical processors. It does Throttle a lot so heat due to the 220W TDP will make it run hotter causing Throddling. To keep it cool you have to have the Case cool, an 360 Fan that paired with liquid cooler to get that thing to stop that. Only way you will get Acturate testing results.launch

A asus sabertooth board like mine would be a better choice just because the cpu power delivery capacitors run cooler allowing for that 5ghz overclock. The board you have is fine for stock settings but usually wont allow for a 5ghz overclock without crazy vrm temps. Mine hit 86 degrees Celsius max at 5ghz using prime 95 for 2 hours. For gaming the vrm wont reach past 75 degrees Celsius. That's at 5ghz and not stock for the temps. At stock the vrm temps wouldn't go past 75 degrees Celsius. Edit: Luckily since patch 1.5 cyberpunk will actually run better on these fx CPU's.launch

Commenters note the chip draws around 200-220W, calling it a power hog compared to contemporaries, with one user citing it as the reason they skipped the entire generation when moving from Phenom II to Ryzen.

@Trueflights

running a 9590 @5ghz, and no problems here. it is a beast of a chip. A bit of a power hog (its only 200w not 220w) and a bit warm if you run turbo or overclock any higher than that, but 5ghz is plenty for just about anything out there.\n\nThey come as a bare chip though, no HS or anything, but that is ok since you would never want to use a stock cooler on a chip like this anyway.launch

just keep in mind that most people who buy 3770k and 4770k i7 chips overclock the daylights out of them while keeping there voltages low and at higher clock speeds my 4.8ghz 3770k beats out the 9590 benchmark while remaining cool. the 9590 requires at least a 240 closed loop it puts out so much heat where as intel chipsets have the same or better performance with less heat. that said i own both amd cpu's and intel and use them depending on what tasks im using them for. and my video cards are AMD with EK waterblocks, so im not an intel fanboy i play both sides of the isle but i think amd went too far with the 9590, too much heat too much power consumption for the performance it gives. if you tried overclocking it to 5.5 as some have said you would burn through the motherboard backplate and melt your system.launch

Several commenters state Intel chips like the overclocked 3770K/4770K or even a 2600K outperformed the 9590 while running cooler, making the AMD chip a weaker choice for pure performance.

@AKATenn

The first 5ghz CPU did fail, it had the ipc of a core2 processor when 2nd generation i7 cpus were out and had more than 30% more IPC... 3ghz 2600k could outperform the fx chips running at 5ghz.launch

I think the 8350 is a great cpu but AMD really messed up with this 9590 cpu, I feel really bad for the people who bought into all there pre-release hype and spent 7 or 800 dollars on it. In the tests the 4770k outperformed it in every single test and the 4770k is far from being the top end processor, Isn't it about number 5 in the Intel top 10? I was surprised by the temps, weren't we originally told it would only work with some motherboards because of the TDP and temps it put out? The temps looked fine to me. The 4770k's the hot one. Like you said if I was doing an AMD build and money was not a factor I'd still go with the 8350 and a watercooler for overclocking it.launch

Users note not all AM3+ boards support the FX-9000 series, stock settings often don't work without both 8-pin and 4-pin CPU power connectors, and a high-end board like the Sabertooth 990FX is needed to unlock its potential.

@MereMortalsAttempt

There is something wrong with your setup. If you get a Asus Sabertooth 990FX R2.0 motherboard you can run 32GB of DDR3 2400MHz ram with the 9590 no problem. That MSI board is terrible. Also, add a Noctua D15 and a fan to the backside of the motherboard. You can overclock the 9590 to 4.9ghz all cores and you will see a decent difference from the 8350… that said FX processors were a long way off from intel at the time even running the hell out of them. if you’re going to build an FX based machine in 2024 at least go full send with the madness 😁launch

I'm currently selling my FX 9590 and Asus Crosshair V Formula-Z mobo. You can't just slap these CPUs in any AM3+ board. You have to look at the CPU support list of the mobo because not all of them support the FX 9000 series. Also these chips don't operate correctly with stock settings. These chips need both the 8-pin and the 4-pin CPU power molexs connected to the board to obtain the stock frequencies. Disable Turbo clock and set it to 4.7 GHz or higher with your own tuning on the NB and HT.launch
