[SOLVED] CPU performance question

[hrissker]

Hello, it has been quite some time since I have posted here, so please forgive me if my format is somewhat off. I have a question regarding the performance upgrade that I would see in 4k gaming. I plan to upgrade from an I7 9700K to the upcoming 13th gen processors, most likely a 13700k, but I am just in awe why CPU's havent advanced much in this timeframe, my 9700k is 14 nanometers and the upcoming gen is half the size, why am I not going to see a 40 % increase in performance or at least IPC ? How much of an upgrade will the 13700k be when comparing IPC or clock rate ? thank you all so much, I have missed this forum.

I will also have an rtx 5090 ti when it comes out, I imagine it will be able to send data to the CPU fairly quick.

Oh and if i may ask, what happened to the users MouseMonkey and SR71 ? they were always answering so many questions.

The first thing to point out is process node size (what they call 14nm or 7nm) isn't actually the size of the transistor, or anything else in the chip at all. That stopped meaning anything tangible around 28nm.

With regards to how much performance you could expect to see, if we went by https://www.cpu-monkey.com/en/compare_cpu-intel_core_i7_9700k-vs-intel_core_i7_13700k you could expect the i7-13700K to be around 40-50% better in single core tests, 60-70% better in multi-core tests.

SR71 is Dark Lord of Tech now. MouseMonkey is not around anymore.

What is with the giant white space between the first part of your post and your last sentence?

13th gen isn't "upcoming", it's been here since October.

Based on the Passmark benchmarks the 13700k is likely, on average, around 52.3% faster single core performance and around 223% faster multithreaded performance. 60-70% doesn't seem accurate based on the numbers I am seeing when correctly using the formula for percentage increase between the multicore scores of the 9700k and 13700k. I'm sure it also greatly depends on WHAT you are running and how well that application or game is optimized for threaded performance.

Either way, as hotaru.hino indicated, the process node size has little to nothing to do with how performance has scaled from generation to generation except in the broadest of terms. Going from the 9700k to the 13700k will be like going from a bicycle to a crotch rocket.

40% is not a bad guess.
13th gen not only clocks higher, but does more work per clock.
Run the cpu-Z bench on your 9700K.
You should see a single thread score of about 566:

If you look on the chart, 13700K scores 864.
The single thread performance is more relevant for games.

You have it a bit backward. It is the cpu that sends frames to the graphics card, and hopefully, the card can display what if is getting quickly.

I have no idea what happened there. Thank you, always wondered what the forums would look like.

Exactly.

 

[hrissker]

Exactly.

Ah it has been awhile. lets hope that the 13th gen is a big leap, and isnt cancelled as the rumors suggest.

 

[Darkbreeze]

What do you mean cancelled? As I said, 13th Gen parts have been available since October of last year. We are already looking forward to 14th Gen Intel parts probably sometime in Q3 of this year. There is nothing to "hope" for because the parts are already in the wild, reviewed and we've been answering questions on them for nearly half a year now. Plus, I already gave you a link that shows the performance difference between what you have now and the 13th Gen parts.

13th gen has been out for over half a year now... been a hot topic around here for a while. Not sure why you think it might be canceled... it's literally out in the wild already!

Dammit... I knew I should have got a new mobo and 13th gen with my recent 4090 purchase. 😆

Seriously though... I didn't see the point for 4K gaming.

I know this topic is solved but I remember you! I stopped posting here for quite some time as well. Just wanted to say that as you get more versed in the current hardware, the more you are going to see just how much CPUs have changed (Intel E-cores, AMD 3D V-cache). It's actually an exciting (if somewhat pricey) time to get back into the swing of things. Welcome back.

Hi, it has been awhile, im trying to learn, it seems somewhat more difficult these days with all the information out there.
