Which cpu is better for gaming?

Just looked up benchmarks, I overstated, it's more of a 10% performance boost to IPC. So on average, the i5 7500 is 10% faster in quad, triple, dual, and single core workloads vs. the 4770.

You sure about 15% better single-threaded performance? I hadn't heard of that big a speed increase from Haswell/Broadwell to Skylake/Kaby Lake. Most of the reviews I've seen have put it closer to a 3%-6% performance increase. Both have a 3.4 GHz base clock speed. The i7 has a 3/4/5/5 turbo so 3.7-3.9 GHz. The i5 turbos to 3.8 GHz. So there's virtually no clock speed difference. And performance at single-threaded tasks should be virtually identical.

Hyperthreading is not like having extra cores. Hyperthreading allows unused parts of the a core to be used by another thread. Crucially, that means is (say) the floating point unit of a core is being used by a thread, it cannot be used by a hyperthreaded thread. So it's primarily tasks where lots of different things need to be done simultaneously which benefit from hyperthreading. In terms of real-life tasks that use the CPU this way, it's usually video rendering, file compression, and some games (have to read benchmarks for each specific game on i5 vs i7). So if you're going to be doing a lot of those tasks, you should prefer the i7.

Other advantages of Kaby Lake (i5-7500):

  • ■ Better integrated GPU if you don't plan to add a graphics card.
    ■ Supports USB-C natively. To add a USB-C slot to the i7-4770 (Haswell), you'd need to install an add-on card.
    ■ Hollywood studios have mandated that 4k movie streams use encryption based on new hardware in Kaby Lake. So if you plan to stream 4k movies to this computer (now or in the future), then Kaby Lake is the safer choice. (I'm opposed to this sort of blatant manipulation and up-sell by Hollywood and Intel, so I will avoid it and just use a dedicated 4k streaming device like a Roku. But I'm not gonna impose my politics onto you, and you should be free to decide for yourself.)
    ■ Less power consumption (84W TDP for the i7-4770, 65W TDP for the i5-7500).

So weigh that against the benefits of hyperthreading, and pick which you think is best.

@solandri Thanks for the big and detailed response, but dude, you make it sound like i want to do 100 procceses in my computer.
I just want to use it for gaming, thats it.

He assume that since it just for gaming, the extra thread and hyper threading are not neccesary.
