So i'm wondering AMD fx9370 claims 200-220TDP and fx8350 is 125TDP.
I wonder is it true?
If the fx9370 runs at 4.7ghz is it really 200-220TDP or lower? How much watts does it consume at 4.7ghz?
tdp is thermal output not power draw, tdp is calculated for worst possible scenario at stock specifications
As soon as you start overclocking any chips on the market, the specs the manufacture labels them with generally no longer have much accuracy. The 8350 will get hotter and consume more power, and the 9370 will get hotter and consume more power. That's really all there is to it.
The TDP is very rough, and is moreso related to heat output for CPU cooler and motherboard requirements (for example you can't use the FX 9370 or 9590 on the 970 motherboards or a couple of the low-end 990 boards). The 9370 will consume more than the 8350, but it's not gonna consume 220W on its own unless you overclock it... but you'll pretty much need a $50+ cooler even running at "stock" speeds.
Here's a review from Hardware Canucks:
http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/62166-amd-fx-9590-review-piledriver-5ghz-17.html
Notice the FX 9590 only consumes about 70W more than the FX 8350, even though it has a 95W higher TDP. And naturally being clocked 300MHz lower, the 9370 will consume a little less than the FX 9590. I can't give you an exact estimate, but I'm gonna guess the 9370 consumes around 40-50W more than the 8350.
Thanks for the reply guys :)
Correct me if i'm wrong, a 9370 would consume about 70w more than a 3770k?
Assuming a stock 3770k consumes 120w while gaming.
Is it worth to buy a fx9370 to replace my 8350/3770k just for the fun of it =X
My reason of thinking of buying it is, they chip is binned and would run at 4.7ghz without OC'ing and if i find its too hot, could i DECLOCK it to 4.0ghz like a 8350?
You're wasting your money. You can OC the 8350 to 4.7 .
+1 if you allready own a FX8350 its point less to upgrade.
The only benefit if you search right you could get a FX9370 with a AMD liquid cooler kit.
But in the end a FX8350 can be easy clocked to 4.5ghz without heat issues.. you would not realy feel the real time performance diffrence between 4.5ghz and 4.7ghz or whatever.
Well, maybe OP is too lazy to OC (and all the baggage that comes with it)...then a FX9000 series would be the right thing to go for.
All comments are very true!
Guess i'm really an AMD enthusiast, i got myself a 3770k last week and somehow i'm slightly moody aboutthe change and want to switch back to AMD as i see no difference in applications.... its like 0 performance increase (i expected some change) so wrong =X Benchmarks say Intel > Amd in single core apps but my god i can't tell the difference when i use both.
Its like i'm finding some sort of reason to switch back to AMD, which is that AMD liquid cooler with the AMD
logo and the (9xxx) printed at the back of the chip =X.
Regarding power usage, i surfed around to check for the power consumption and can only find Nicolas11x12TECHX doing FX vs Intel benchmarks. (http://www.youtube.com/watch?v=7td96oyniyk).
Seems that: (Stock speeds)
3770k
Idle: 60
load: 132
4770k
Idle: 88
load: 186
8350
idle: 97
load: 227
8350 @ 4.8ghz
idle: 151
load: 315.
Say if i disable turbo on the 9370 and clock it to 4.0ghz i would theoretically be getting this results idle: 97
load: 227?
I seen alot of forums say for a 9xxx series chip, you'd need 1000w PSU, is that true?
I did some calculations and figured i'd be using around 550w with a gtx780.
What do you think the watt would be?
Well, on Pistol's build she has an 850watt PSU and she has a FX9590.

edit: As far as power consumption goes, there's a
- AMD Cool'n'Quiet
- C1E Support
- Core C6 State Support
feature too which does wonders for power consumption and heat. The only time I don't use this feature is when I'm gaming (to which I turn the power option to High Performance in Windows which disables CPU parking). You could try that before downclocking because Windows will do it for you automatically.
1000W psu for a FX9590? haha Thats offcourse just bullshit.
Power numbers in benchmarks are numbers for a complete system not just a cpu.
650W psu will be more then enough.
The system will maybe draw 450W max
also the video of NicollasX12 is funny, he excaly using one of the most terrible motherboards you could possibly get for an FX8350. it will get throttled, so those benchmarks are realy not accurate.
Maybe. I have tried three different 8350 CPUs and none of them would be stable over 4.6 GHz. Boot and run yes, but not AVX stable.
The good chips are sold as 9370/9590s, the runts of the litter become 8320/8350s.
Edit: I mean to write "only one of them". My current 8350 can run at 4.8GHz, although at 1.56-1.58 Volts. Backed off to 4.6GHz and have very cool and quiet system instead at 1.48-1.5 Volts. It can do 4.4GHz at 1.4V, stock is 1.36V and I have had it stable at 4GHz and 1.30V. I use CnQ and C1E, at idle it sits at 2GHz and 1.0V.
I refuse to believe that you did a stable OC or had a decent motherboard to begin with,If my 8320 which is the lowest binned CPU is 100% stable and doesn't break a sweat at 4.5ghz with the hyper 212 how in the world couldn't you manage to get 4.6 from 8350's . WTF?
+1 The 8350 hits <200w tops,at 100% usage.
you're just lucky is all
even before the 9xxx there were many 8320s that couldn't push past 4.0, there's nothing that says it has to be able overclock past it's stock clocks
Silicon lottery is nuts these days... know one guy whose 4670K wasn't even stable at 100MHz over the stock turbo speed haha... talk about a waste of money on a K chip :P
Yeah motherboard plays a big factor, there are a lot of AM3+ boards that won't support the eight core chips, and there are a ton of boards that have terrible power saving features. I've also found my fair share of benchmarks showing the FX 8350 drawing LESS than a 3770K in idle states. Typically it appears the 8350 will draw around 60-70W more than the 3770K/4770K under load at stock... for the 9370 you can probably expect it to draw maybe 120W more than a stock 3770K/4770K, or again ~70W vs an overclocked i7.
Although I thought that a 990FX Extreme 3 is fine for an FX 8350? (It's certainly far from the best board in terms of power efficiency lol)
Can't wait to install these two bad boys :D!
I think i'll de-clock it to 4.0GHz like my 8350 and off turbo as im jsut afraid it'll consume too much power :)
well Asrock 990FX Extreme 3 4+1 powerphase and cheap crappy vrm´s...
So no its not realy great lol ☺
haha nice, no not underclock, just tune that baby up ☺
Crosshair V Formula Z can handle that without any pain.
