Core i7 3770K  vs FX 8350 

And because Ivy Bridge chips like the Core i7-3770K are intended for more middle-of-the-road users, they come loaded with integrated graphics systems that can drive up to three independent displays and support HDMI 1.4a and its associated high-quality audio, in addition to InTru 3D (for stereoscopic 3D) and HD video conferencing.
Core i7 3770K

It's hard to imagine any desktop PC user ever needing more performance than the new Intel Core i7 3770K serves up.

The CPU is not the only variable when it comes to frames, sorry. Also, you're*
Can It Beat 5960X
i5 has 1st gen processor and 5th gen processor. u mean amd's best processor like (fx 9590/8350) can't beat 1st gen i5. it's absolutely nonsence. FX 9590/8350 can beat any 3rd gen i5+4th gen (i5 4440/4460/4590) easily. u can check benchmark.
- You're. - , my - On YouTube. - Two - CPUs. - played. - I'm not an AMD - I - an extra
Actually , it can make a significant difference . Just look at the more cpu demanding games : if i can only use 4 cores , amd may be a bottleneck because amd cores are weak. Just look at crisis 3 with an amd cpu vs intel cpu.
I got my i7 3770k for 100$ , and i run it a 4.9 ghz . It beats any amd processor i can think of.
Linux, so light.
CPU will not effect FPS that much at all, your GPU will. People call Intel users fanboys, but don't understand CPU's at all!
Actually Benchmarks that I have done puts the intel at over 25% faster per core, clock speed mean nothing if CPU is slower. If the program runs over 4 cores AMD will be faster, otherwise i7 is 25% faster!
And 25% slower cores in GFlops and actual performance, so 4 Intel cores = 5 AMD cores and hardly any game uses more then 4 cores so you are wasting 4 cores and sitting with 4 cores with 25% less speed in Battlefield.
i7 has 25% faster cores, so unless the program uses more then 4 cores and the CPU power used is also more it will be slower.
Almost every benchmark puts the i7 ahead and the i7 3770k was pretty cheap a few years back (20-30 bucks difference between it and a FX 8350). People say that reviewers lie but the bottom line is that the intel CPU is 10% faster at most tasks. Most of the benchmarks above use all the CPU cores, however most real World applications use 1-4 cores and in a 1-4 core game such as battlefield the i7 creams the AMD as it is 25% faster per core. Unless you open 2 Visual Studio's, 2 SQL server studio's, Android SDK, Skype, Outlook, 2 different Web Browsers, 2 Windows Media players and Star Citizen at the same time the i7 will be faster.
Your so stupid, My IQ went down by 10 just from reading that. on youtube there is a video comparing these to cpu's together and guess what? There was only a 3-5 FPS difference on each game played, He also showed how he could render a video while playing ArmA 3 with the AMD 8350 where as on the other hand.. the 3770k couldn't, I ain't a AMD fanboy i use intel myself, but paying a extra 150 quid is not worth an extra 5 FPS
By the way I used the same ram and video card in both machines
I think it is funny. I have a i7 4770. It runs ok. But here is the catcher. I just bought a amd fx-9370 16gb ram radeon r9 290x 4gb gddr5 Kingston 120gb ssd 3tb hd liqtech 240 liquid cooler roswill 850wt extreme edition psu. I play games such as cod aw at highest settings. Ok the i7 was at 110fps which is GOOD. But the so called underdog amd was pushing a mind blowing 190+fps. So intel can kiss my A@$
to have a AMD processor is like to have a Nissan GTR with a brick under the throttle pedal, (the brick is the software), software must be optimized to take all the power from the cpu, untill that moment, intel will win anytime PD: i have a phenom II X6
at the end of the day, everyone is going to laugh at you for having an AMD processor because AMD is for homos
sorry for the spelling fails guys.
Well i i think the price makes the fx 8350 the winner. and the i7 is better for gaming wereas the fx 8350 excells at productivity task. or so i have been told. i ended up buying the fx 8350 and i am very pleased with the preformance. the only problem i have with the fx 8350 is the tempreature. it is hard to keep it cool. but what do you expect with 8 cores jammed into such a small space. but if you have the money the 17 would be the way to go.
Man I want to spend 130 more so I can get 5 more frames! POWER TO THE DERP!
God damn fights just over fucking processor brands!!?!?!?
AMD is better than Intel because AMD 8 and Intel 4 core and AMD 4ghz to 4,2ghz and intel is 3,5 and cant more then you alone choice
The difference between 199 and 229 is not 100 bucks. Having a budget is a valid point but it will not mean you can out perform Intel which is what most people here seem to think.
intel is 100 bucks expensive. If u are a gamer and u are on a budget. Im sorry to say that amd is a king. Cos it is 100 bucks cheaper. And u still get good performance and crazy speed over the amd.
Sorry guy that is a flat out lie. I can tell you that because I own both an 8350 fx, 4670k and a 3770k and a pentium g3220 which is a dual core with no HT. I played crysis 3 on all the beefiest settings and 1 core was at 100 and the other was at 80%. Now, lets say crysis was only able to utilize 2 cores max, that would mean that on an amd system both cores would be at 100% and there would be considerable performance degradation as AMD's IPC is about half of intels. Now luckily crysis can utilize more than 2 cores but all benchmarks still show that IPC is king and that AMD has consistently lower minimum and maximum frame rates compared to intels. Its just fact. Get over the fan boy stage.
