We are discussing price difference and performance gain, don't change subjects. The FX6300 costs on avarage almost half of what the 6600K does, and with a little overclocking you can get the same performance and shift the cost elsewhere (better gpu, higher speed ram, whavever).
Im in the US. Why would i care about other countries prices? Anyway. The FX6300 is only 89.99USD$ here. Theres no need to buy CPU's or PC hardware on amazon when there are others stores selling it for cheaper prices.
I'm in Spain. Amazon.es links: -FX 6300: https://www.amazon.es/AMD-FX-6300-Procesador-Socket-Full/dp/B009O7YORK/ref=sr_1_1?ie=UTF8&qid=1461319234&sr=8-1&keywords=fx6300 95€ which is about 107$ -i5 6600K: https://www.amazon.es/Intel-BX80662I56600K-Procesador-Skylake-socket/dp/B010T6DCBS/ref=sr_1_1?ie=UTF8&qid=1461319247&sr=8-1&keywords=+i5+6600K 233€ which is about 262$ Checks out for the rest of europe.
In what country? In japan? Here in the US, the 4690K is at 199.99USD$ at microcenter, and the i5 6600K at 209.99USD$.
Pulling the prices from amazon, half a year later, the FX 6300 stands at 95€ and the 4690K stands at 247€. That's a 152€ difference, definitely not exaggeration.
Actually the FX isn't bottlenecking my 970 in the least.
There is no i5 with 8 threads in existance.
Not even the i5 4690K is 140$ more than the FX 6300. That is exaggeration
Now try using a 970 or 980 with those CPU and see how the FX will bottleneck those cards.
So? and after market CPU is cheap
sure... here.. http://cpuboss.com/cpus/Intel-Core-i7-4790K-vs-AMD-FX-9590
which one is better between i7 5960x and fx 9590? will you please help me to select...
"Yes the Intel 3570k is faster but is it a $100 faster?? NO!!" - it is right comment. I buy AMD FX-6300 because is cheaper and able to use to all typical apps (ie. cad apps too) and games (my comp. costs 500 usd) . If someone need to play with nevest games or use proffessional graphics/music soft must achive not only cpu but everything else for real money.
Here's a screenshot btween 2 cpus that i own. As you see, intel performs better even at multicore tasks, not just in single cores! As you can see, If i overclock my i5-750 to an almost equal frequency (4,1 GHz) with my FX-6300 (4,3GHZ) it performs much better!! I cant imagine the newer i5-3570K overclocked at he SAME frequency with the FX-6300 how much better will perform!!
intel is better just in single cores and by a little....amd is the winner, for the price....it´s money better invested....
you must be an intel user....
There are no 4 core hyperthreaded i5 CPUs.
the main question is"what if i only have 100$ to spend on cpu" which would win then ?
intel i5 3570K has 4 cores and 8 threads no 4 as you described!
If you overclock the fx 6300 to 4,7 Ghz, it will hardly reach 170 watts. That isn't a reason to buy a 1600 watt psu instead of a 650 one... Only if you want to install dual 295X2, but that is another story ;)
FX beats i3 only in multythreaded benchmarks, loaded 6(!!) cores at once. Most people don't load so many cores at the same time, i3 is better at quad core applications and MUCH better at dual\single core apps. Also, you ever wondered why they showed so few gaming benchamrks in this video? see more and you'll see what I mean. Also, 4-th gen i3 consumes about 25 watts less on idle, which means it's a signficantly cheaper processr than FX 6300
errr https://www.youtube.com/watch?v=aXPK9doyMLg
this is not about compairing a 6core to a 2core cpu. it is a compairsion between 2 low-end CPUs. no matter how many cores they have. and in the low-end amd is way better than intel. BTW: technically the fx6300 isnt even a full 6core CPU. Its more like a 3 Core CPU because every core module has only one floating-point-coprocessor which is important to gaming.
I am using pc for gaming and video editing, and so far from my experience, intel beats amd, especualy in these 2 cpus. I have both cpus, fx 6300 is slower in gaming and video editing for me. Example i need more then 60minutes to render 2hr mpeg2 video file, but i5 3570k does the job for 40-50minutes. That is a big difference when i have to edit 10+ hrs. of video material. Plus in games i play WoT, BF3 BF4 and some few more, also i5 beats this fx, games run much smoother. That is just me experience, i dont know was it because i maybe bought bad amd cpu, bad factory made, or bad mobo (asus A97 chipset) but i saw this as a waste of money. Haters, relax. ;P
Don't forget a good power supply. You dont want your overclocking to go bad.
