Should I upgrade from 4790k to 9900k or wait for intel 10nm process?

I’m running on a z97 and I’m overdue for an upgrade. I’m running a 1080ti and want to make sure I’m not bottlenecked. I’m not usually anywhere near 100% when gaming so I’ve put it off till now.

I’m playing games at 1440p so generally my gpu is taxed far more than my cpu.

I hear that 10nm is coming out during this summer or in q4 of 2019. Opinions welcome.

Hi,
Doubt it will get much better quad to 8 core

That’s what I figured too. But I was looking at some benchmarks and somehow they were getting 33% improvement over the 4790k...maybe it’s the memory difference from ddr3 to 4?

No. There is no point in upgrading for games that don't exist yet and there are no games that a 4790K cant handle.

By the time you really need it, there will be better options.

You would get slightly better average FPS with a newer CPU but the difference would be pretty small, probably not even enough to notice.

Is there any gaming performance improvement going from ddr3 to ddr4?

I did notice that in COD WWII my cpu was going to 100 and my memory was making out though.

Which CPU's were they comparing when you reference this 33% gap?

Depending on the the game and how large of a gap between memory speeds, you're probably not going to see much more than a 3-5% from memory alone (maybe larger gaps in cpu heavy games like MMO's and some RTS style games upwards 5-10%).

You can probably hold over until Intel decides to actually revamp their architecture, get Zen 2, or wait for whatever platform comes out with PCI-E 4 and DDR5, especially if you're primarily gaming at 1440p.

I believe they were using 4790k, and the flagship of every generation for the z series chipsets, all the way up to 9900k. They might have been using 1080p, and from what I understand, at the lower resolutions, you’re more cpu bound than gpu bound.

If they're testing both cpu's stock, theres a large discrepancy between stock boost clocks for say your 4790k vs a 9900k. In your case, you've overclocked to 4.7ghz so vs a stock 9900k your all core turbo will actually be 100mhz faster while your single core turbo will be 300mhz lower (or 200mhz cant remember 9900k single core turbo). So the difference, at least at 1080p, with your PC vs their test system will be a significantly smaller gap (<10%) due to slight IPC differences and much smaller differences in clock speeds.

Like everyone has pretty much stated, no reason to upgrade your CPU if all you're doing is gaming @ 1440p atm. The only reason would be if you needed more cores/threads for productivity software or say streaming.

That’s what I figured too. Thanks for confirming. I’m not doing anything productivity related.
