ok I asked a question a good while back about this and was told that a core i7 has little to no bennifit over a core i5 in gaming. and that it was only marginably better in video recoding/encoding.

how true is this, is because (and I wish I bookmarked where I read this) but I seen charts and such that if my memory serves right that clearly the core i7 has a lot better performance then a core i5 even in gamming.

I am aware that the i7 is factory clocked higher but this was with both cpu';s running at the same speed. so has something changed? is the i7 going to be a good bit faster then a core i5 in gaming when both are overclocked too the same speed?

also although the new core i5 4690k has a slower stock speed it easily overclocks to 4.4ghz is that true?

It is however beneficial if you have multiple programs running at the same time. I am, for example, usually running scientific calculations in one thread at the same time while I game, and have a browser and some background things running. In my case the difference is huge. If you only game on the machine, there is little difference except the clock difference. In CPU bound games, that might make a small difference.
 
Very little benefit in MOST games. About 2-3 fps increase. A few select games can make use of the i7's Hyper-Threading technology and those few games will see a bigger improvement.

The i7 is always better and faster than the i5 regardless of category -- gaming, video editing, etc.. But it's not better by enough to warrant a $100 premium cost. And not many games support Hyper-Threading to make it a worthwhile purchase. It's a bang for buck type of deal.

And yes, 4.4Ghz overclock is easy to hit.
 
As it stands now, an i5 is perfectly sufficient for gaming, even with so-called multi-threaded games such as Watch Dogs. Good gaming performance is just as much down to good development as it is to good hardware. The caveat is that in the next few years, games may start to utilise multiple threads properly. The trouble is, nobody knows.

Benchmark results will always favour the i7 because the software can make use of the extra threads.

Overclocking is never an exact science. Identical processors on the same motherboard, with the same cooler in the same conditions can yield different results. Some processors are just more flexible in their overclocking than others.

The bottom line is you pick your hardware depending on your use - if you're gonna be doing 3D rendering for example, an i7 will be hugely better than an i5 - because that kind of software can fully make use of the additional power of the i7

There is not a single game on the market that is limited to a large enough degree by an i5 4690k to warrant buying an i7 , as long as you have a good GPU and ply on high, such that most of the processing is done in the gpu. Physx might be a problem if you run it as software, so if you want physx, get a nvidia GPU.

These benchmarks: http://www.techpowerup.com/reviews/Intel/Core_i5_4670K_and_i7_4770K_Comparison/8.html show that even in the highly cpu dependent BF3, this only amounts to about 5 fps. My guess is, the difference is smaller if you run it on a modern gpu.

Update: Found another one: http://www.ocaholic.ch/modules/smartsection/item.php?itemid=1061&page=4 Here you can see the difference is minimal with a good GPU on high.
 


In general, games that aren't graphically demanding tend to require more out of the processor, but it's relative and will still vary from game to game.

For example, if a game uses three cores then a dual-core Pentium will struggle. If you play the same game on an i5, the performance will be noticeably better. If you then step up to an i7, you won't see any improvement as the game only makes use of three cores.

MMOs will play just fine on an i5.

Reply specifically to the Physx part - if you are wanting to use a AMD graphics card i would recommend the i7 over the i7 for the Physics score as shown here http://

Otherwise if you are getting nVidia which has Physx built in go for the i5.

it is higher clocked, that is the sole reason i'm getting the i7, if it wasn't clocked so high i'd be just like you taking in the consideration an probably getting the i5 because all i really need it for is simulating flight simulator and sims3/4 for my niece and general everyday use.

with the benchmarks i've seen, and videos on digitalfoundary, and tek syndicate and other reliable youtubers......... lesser than 2%, even lesser than 1% i most cases........

I found these links a good read. I am at the point now of deciding i5-i7. The links provide the clear cut answer.

maybe now it isnt, but on the next months and years you will get the difference between a i5 medium/high specs for a high/ultra specs

Really good replies here, glad I went for the i5 4690k over an i7 , would of been a great waste of cash , which I have now put into the gfx and bumped up to a gtx 770 4gb through the extra budget :) thanks guys you've confirmed my theories.

One question though, I haven't done a build in quite a long time, and I'm a bit confused at the memory speeds stated on this cpu, it says 1333/ 1600 ? why is this, the M Board I am buying is a z97 and can take up to 3200, can I go higher or am I limited to 1600 b'cause of the cpu?

what about if I plan on using 2 maybe even 3 radeon 280x graphics cards would the i7 be worth the extra in a multi gpu setup I recently heard that multi gpu's can use the extra cores/hyperthread

hmm one of my favorite games guild wars 2 I believe is cpu bound exspecialy when playing world vs world I wonder thouh if cpu bound games if it will matter a lot there or not?i5 vs i7

i ran guild wars 2 on a 2600k at 4.6ghz and a 3570k at 4.5ghz no difference i never saw guildwars 2 using more than 4 threads and my fps was still gpu limited even with a amd r290

When it comes to video editing my i7 4790k takes about fifty percent less time than my previous i5-760. A HD video that took four hours to convert is now reduced to just two hours. But waiting two hours for the damn conversion to finish is ridiculous. How i wish i had bought an octacore! Games don’t stress the system as much as video and photo editing. By photo editing i mean the 3D rendering in Photoshop. A good video card and a simple quad core can run any game without issues.
