Sorry to disprove...but..I currently have a crosshair V formula Z motherboard, with AMD FX 9590 and cooling it with cooler master v8 GTS and it rarely goes above 40 C. (Granted...the cpu is not OC at all..running 4.7ghz.....but still is being air cooled.
It's true, Turbo stays on most of the time with my Hyper 212 Evo. It's surprising yet true
the actual tests show 4790 as better than the 6700, what i want to know, is why am i seeing a 4790 in a "6700k vs a 9590" test? plus n.d in some and 0.0 on some, looks like it wasnt done, or wasnt done proper? am i right or wrong?
And a year later someone replys lol
It's easy to get 5GHz on air on the 9590.
You need more than one comparison for something to be conclusive.
Watch the 7350k - 7500 comparison by RandomGaminginHD. You're probably wrong.
Hyperthread = 30% of performance of a physical core.
Yes it can
That isn't true. I have the "volcano CPU" AMD-FX 9590 yet I can keep it cool with a Dark Rock Pro! 3 heat sink. It never goes past 50 degree's Celsius
Okay now you know that's a lie. The 9590 will kick your 3570k's behind all the time. Give credit where its due. Your i5 is good, but not that good. That i5, while having better single core performance, only has 4 cores (not hyperthreaded btw) clocked at 3.4 ghz stock. the 9590 has 8 (its really 4 modules with 2 cores per module) but the point is it has 8 threads. its going to complete all multithreaded workloads first. Gaming in DX11 will be better on the i5 because it doesn't ever really utilize more than 4 cores, and in that kind of workload where only 4 cores are used, having better single core performance is going to net better results. Here's the thing, you might be able to upgrade in the future but you're still on an outdated platform that hasn't had any new motherboards released for it in a long time. The 9590 has access to more updated motherboards. i have an asus aura am3+ mobo with usb 3.1 type a on it. Even though am3+ is outdated, at least it still has new motherboards with more modern connectivity. so while you have a better upgrade path along your generation of processors that you went with, the am3+ platform especially with a 9590, or even an 8350, will still hold up for a longer amount of time, especially in gaming since they are starting to utilize multiple cores in DX12 and Vulkan which means less overall money spent in the long run before you want to upgrade in generation of hardware. i have a 6350. while i do plan on upgrading to zen when it comes out, its still a viable processor. its not as fast as your i5 but it comes close. i plan on giving it to a friend once i do and I'm sure it wont be disappointing. its still snappy and i haven't had a single bit of lag while using it. and it sits at a nice and cool 52C at full load underneath the wraith cooler it came with. Just like yours, the fx line may be old, but it is by no means bad especially for the price.
It's possible if you have Noctua's NH-D14 or D15, also a few other dual-tower coolers like Phanteks can get away with it too. It's just what some people prefer over water
Hyperthreading makes the 6700k have as many cores as the 9590 does and at the same performance because even AMD's processors have shared cache for every 2 cores, which limits speed a lot.
hehe it took you long enough to realise that. I was a AMD fanboy myself since 2003, that is when i have built my first pc with an Amd Duron, Aopen motherboard, 256 mb of ram and Nvidia 440 mx with 64 mb of vram. And yes the year i said goodbye to AMD was 2013. I went to Intel i5 3570k and it's still beats FX9590 :D That's well invested money.
A funny and unfair comparison, have your opinion.
As someone who's spent a year with the FX-9590 and a week with the i7-6700k: -The 6700k runs hotter (celcius), idling at 23 degrees@11watts, prime95 65 degrees@60watts with stock clock & hyperthreading -> FX9590 idling 15 degrees@30watts prime95 52 degrees 160watts@5ghz. I use a pure copper 12mm thick waterblock, 2 radiators 2 pumps and a reservoir. So cooling is not an issue for both systems. To reach best potential I can't see how either systems survive without watercooling, I've never tried air cooling. -CS:GO with an i7 6700k I see the FPS counter jitter at 200fps-500fps -> FX9590 150-300fps Fraps maintains 120-140fps with i7 6700k | FX9590 70-120fps with jitterbug. -Blade & Soul in soulstone plains with ~30-40 players in one spot I get 20-120fps i7 6700k, 10-60fps with a 9590. A terribly optimized game to begin with. -Video rendering Adobe Premiere pro the i7 6700k is 2 minutes faster in rendering a video compared to an FX9590 -Adobe photoshop doesn't seem to use all 8 "cores" on either but the Intel i7 definitely feels faster. -Long term you will definitely pay more money through electricity bills from an FX9590 that will balance out with an i7 6700k. i7 6700k > FX9590 As an AMD Fanboy, I will admit the i7 6700k is better overall. Not every application will use 8 cores but most applications will use 1-4 cores in which windows is capable to switch between using 4 physical cores and 8 logical "hyperthreading" cores. I was an AMD enthusiast since the Phenom ii 1090t, going to the 4350 -> 6300 -> 8350 -> 9590. Goodbye AMD... for now :<
There's the GeekBench 3 (Multi-core). The 6700k is clearly better, but it's newer and quite expensive. I'm waiting for Zen tho :-)
but only problem is that u always need liquid cooling for the AMD, or u will wait to see liquid plastic. On Liquid Helium, amd reaches 8.4 GHz.
Basically all FX processors are known for their number of cores and their clock speeds and most importantly their overclocking capabilities. That is something being ignored here.
The FX 9590 can't run on air at all...
I believe this comparison is unfair as there are no benchmarks for multi-core performance - only single core. It is well known that AMD processors are usually best with multi-core performance whilst Intel processors are usually best at single-core performance, so comparing with only single-core benchmarks possibly optimises the results in Intel's favour.
you can use the Noctua NH-D14 for it or the silverstone silverarrow.
But why would you want to run it on air when the stock cooler is a water cooler?
The FX 9590 is more of a lie. 5GHz on AIR? My balls..
