Difference between i7 4790k and i7 7700k?

[YourComputerGeek]

Hi,

     I considering giving my system a huge upgrade, i recently bought a GTX 1080 ti, but I'm afraid that my CPU will bottle neck it's performance! Any suggestions on what i should do? Is it worth to go from a  4790k to a 7700k?

Difference is gonna be 10%, max. It's not worth the upgrade.

Alright, what about ryzen by any chance? Idk tho, not a fan on how they over hype their products

It depends on what you're planning to do with your old CPU. If you plan on selling it and you have some money burning a hole in your pocket, I would say go for it since Kaby Lake has some minor IPC (instructions per clock) improvements over Haswell and the 7700k has a quite a bit higher clock speed as well. If you're keeping the 4790k, though, I wouldn't recommend spending about $350 (+the cost of a new motherboard and memory) just for those rather minor improvements.

Like other's said 10% IPC improvement with another 2-4% improvement via higher frequency capability.

 

The 1080 Ti will not get bottlenecked. Even core i5s will do fine in keeping up with that behemoth. Don't sweat it.

If you're planning on gaming only, I would stick with Intel. Ryzen is more aimed at content creators and streamers due to their higher core/thread count. Their lower clock speed will probably result in lower FPS in certain games when compared to a 4790k with a decent OC.

Correct me if i'm wrong, but more PCI lanes, the better for a card like the GTX 1080 ti?

If you're doing multi threaded stuff like video editing then sure, go for it, but if you're only gaming it's worse than a 7700k.

This would only be true if you had loads of other expansion cards in your system. The PCIe 16x slot physically can't utilise more than 16 PCIe lanes thus the PCIe 16x name.

Kaby lake and haswell have the same amount of pcie lanes from the CPU itself. Anyhow, x8 vs x16 still has no performance difference.

That really depends on the game. Some titles like BF1 really use a lot of CPU resources and can result in the GPU getting bottlenecked by the CPU (if you're playing at lower resolutions)

Yeah true true. However we've got to differentiate the difference between technical bottlenecking and bottlenecking that affects the gaming expereince. Bottlenecking at super high FPS I wouldn't consider a bad bottleneck.

I will be playing at 4k, will that start to see a bottleneck? But, i don't play BF4

If you're just playing games there's not a CPU you can buy that will give you a noticeably better experience than your 4790k even @ stock. I do recommend you overclock it if you can, hell it's free fps

At 4k you should be alright since the GPU will be busy enough rendering more than 60 FPS at that high of a resolution.

Overclocked 4790k to about 4.6GHz will give you about the same performance as 7700k on stock speeds, not really worth the upgrade.

I jumped ona Ryzen 1700 from a 4790k - Why?

 

I looked on ebay and the stuff I had was selling REALLY well. My CPU sold for £220, my board £90, my ram (2x 16gb kits) £155, and some other pieces I had lying around like a fan controller, mouse, keyboard and soundblaster Z - It totalled £540 ish - This basically paid for my upgrade albeit I had to throw money in for the ram.

 

Other reasons? Newer platform - I can run my m.2 drive at full speed (no room in my case with bottom radiator to use a PCI adapter) a newer platform, DDR4 and hell - LOTS more cores.

 

 

Initial gaming results is slower on benchmarks - mainly because my ram isn't officially supported by gigabyte (another issue with Ryzen, Ram is a bitch) so its running 2133mhz, a massive killer - however my chip is decent, 4 ghz @ 1.380v - although, gaming does feel smoother - don't ask me why, it just feels smoother.

 

I did some benchmarks in my build log of 4790k vs my ryzen build - you can go have a look if ya like, remember the Ryzen is massively gimped @ 2133mhz ram

Would you say it's worth what you did? Would you recommend it?

Depends on a few things:

 

a) Will you ever use the extra cores?

b) Are you willing to have sub par performance whilst waiting on updates and devs to implement Ryzen tech into their games?

 

 

However at 4k, you probably won't notice the difference anyway - i'm glad I changed, do I wish I went 7700k? At this time yes - but that purely down to how it all performs at this time - I know it will get better and the performance I have at 1440P is fine, its only when you look at charts that you wonder

 

as + the multithread performance is better than a $1000 6900k - that's what makes me smile lol
