EXPERIENCES NEEDED (CPU change)

[shadowsite]

Hello everyone, hope you have a nice evening!

I am currently running an xt7900xtx with an I7 9700K at stock speed (3.6Ghz).

I now got the opportunity to upgrade it to an 7800x3d and wanted to ask:

Will the CPU upgrade immensely boost ym FPS in games or will the change be minor?
Basically the cost of the upgrade would "only" be 170€, but I wouldn't want to do it if the upgrade is really smoll.

Maybe someone was in the same position since the 9700K was kind of the allrounder a few years ago, so I guess many people will have in their system (or had it in theirs).

Thanks for all suggestions :D

Edit: I did do some research, but I couldn't find anything regarding an upgrade from the 9700K

it will be a massive upgrade in games that were CPU bound.....yes its worth the upgrade to go to the best gaming CPU on the market right now.....

I am aware of different "versus" sites, but we all know that these don't reflect the truth really.

I had hoped someone who made the exact same change (very specific, I know) could give some experiences with this :)

When it comes to the Ryzen 7 9700X vs 7700X and 7800X3D, the amount of screwing AMD faced was universal, not just from Microsoft, but also from their own marketing and independent outlets it seems.

Watch this also if you use W11.

Overall wouldn't the 7800x3d be an upgrade to PCIe 4.0, I never used the I7 9700K but it's 3.0 correct.

Depends on what resolution you are running. If it is 4K then in most games no.

Would say for 170 euros it`s well worth it to modernize the system even if it doesn`t necessarily boost all the games.

The i7-9700K is definitely going to bottleneck that GPU, considering it was in the same performance class as Ryzen 3000 series which had bottlenecked the 2080 Ti, which is only around 6750-XT or RX 6800 level performance. Any time the CPU's performance becomes the major bottleneck in the system, that 7900-XTX will underperform.

You need a new motherboard and probably new RAM as well, especially if you're interested in Ryzen 7000 or 9000 series as AM5 doesn't support DDR4. 7800X3D is still currently the best for gaming performance until the 9800X3D launches later this year or early next year. 9900K won't make much of a difference as it was essentially just a better binned 9700K but with HyperThreading, your only option is to move to a newer CPU socket.

Make sure your PSU is up to the task as well, for a 7800X3D I would suggest a 750W when paired with that GPU at minimum, ideally at least 850W for most configurations

Thank you verym uch for that detailed answer!

As for my resolution: I play in Ultrawide (3440x1440).

Do I get that right: If I upgrade to a 7800x3d, I NEED new DDR5 Ram?

You need a new motherboard and new RAM because the CPU doesn't support DDR4, and you can't just put any CPU into any socket, you're not just talking about buying a new CPU here, it requires replacing several components because they just aren't all compatible with each other

Socket AM5 has 1718 pins, your motherboard is Socket LGA1151 which has 1151 pins, and the chipset you have only supports Coffee Lake processors (8th and 9th generation Intel)

Intel supports DDR4 with their latest socket if you get a DDR4/D4 version of a motherboard but at this time, it's just not worth it as the 7800X3D is faster, and because of potential problems with Raptor Lake CPUs over 65W, and if your DDR4 is too slow anyway (i.e. common DDR4-3200), it's just going to slightly hold it back even more

I went from a 9700k to a 7800x3d with my RTX 3080 playing 1440p 270hz, pretty much 2x or more my fps in every game I play. Given I play competitive settings (low everything, sometimes 4:3) on every game I play it was hugely noticeable and sometimes even 3x my fps

I wouldnt even question it aside form the fact that the 9800x3d will be set to release relatively soon so Id keep an eye out for that although it would be most expensive than buying a 7800x3d now.

EDIT
You will need to buy a new motherboard, ram and probably CPU cooler if you dont have the AM5 bracket lying around so its compatible for the new cpu, its a pretty substantial upgrade.

its gen 5 with main 16 slot and one M.2 slot supporting gen 5 IF he is on a X670 motherboard or higher chipset....lower end mothers like a 650 will only have 8 lanes of gen 5 with most motherboard makers using it for 2 M.2 slots with the main 16 slot only being gen 4 for the GPU

so depending on motherboard it could be gen 5 as the 7800x3d supports it....

I don't have the sort of personal experience you need, but perhaps I can help you on the research front:

170€ for a 7800x3D is a good price assuming it's a functional chip from a trustworthy source, esp. considering how new stock climbed back up in price, and the only way up to go on your existing platform would be the 9900k so I think you should jump at the opportunity. I don't even think the price will drop below that even if rumors of arrow lake processors in October turn out to be true.

And yeah, there's a whole reddit thread about this. Everybody who posted there is very happy with the in-game perf. uplift. One person reports personal G.P.U. utilization jumping from 80% to 100%.

Also you're having trouble because the 9700k was already three generations old by the time the 7800x3D was out. It's pretty rare for a C.P.U. that old to still be of relevance to its original market segmentation position, and esp. not an Intel part since intel boards usually only support a couple of generations of C.P.U.

If you watch the Gamer's nexus review of the 7800x3D though you'll get the sense of how much better it is because although they don't necessarily include a 9700k, they do include a 10900k. A 9700k isn't going to be better than a 10900 any way you slice the cake, so when you see a jump from 207.3 F.P.S. to 385.9 in Shadow of the Tomb Raider, you know you're gong to be in for a pretty massive upgrade. In fact, the 1% lows on the 7800x3D are 222.8, which is higher than the average framerate on the 10900k. As for Cyberpunk 2077, we're seeing a pretty similar story. It's a jump from 132.3 to 193.7, with 145.4 in the 1% lows.

This will be an absolutely tremendous upgrade.

I just recently changed my gaming setup from a 9700k to a 7800x3d.
It is a great upgrade you will notice it.
That video card you have is wasted on a 9700k.

Don't use Userbenchmark for CPU comparison especially between AMd and Intel, userbenchmark has been shown/proven to be biased against AMD. With the 7800X3D + RX 7900XTX, OP should see improved overall framerate, plus more consistent 1% lows, so OP should get a more consistent gameplay experience overall.

I'd noticed better or more consistent 1% lows and higher max framerate when I went from a 5900X to a 5700X3D (with a MERC310 RX 7900 XTX + 32GB RAM). So, a 7800X3D would give OP a better gaming experience (assuming OP has a a high refresh rate monitor to go with a high end system).
