Performance problem with a rtx 3070 and ryzen 2600

[Luca1469]

So, i was looking on a ebay equivalent in my country and i found a well-priced rtx 3070, at 350$.

I bought it and 2 days ago it arrived. I didn't have much time to test it because I went on vacation yesterday, but still managed to install it in my pc and run some games and a stress test.

In valorant I got only 165 fps with no frame drops but still I was expecting more. Next, I tried Fortnite and I got a little over 100 fps, but with big frame drops (sometimes to low 40s). And then I ran FurMark and the gpu ran fine, with no frame drops or artifacts, no crashes, everything normal.

So rn I don't know if I have a cpu bottleneck or if the gpu has some problem of some sort.

Right now my config is:

-Palit GamingPro Rtx 3070 OC

-Ryzen 5 2600

-32gb 3200mhz (but i disabled XMP bc they weren't stable so they are at 2666mhz) G.skill Ripjaws

-600W PSU( I don't remember the brand rn)

-Gigabyte 450M DS3H

-1 Tb Samsung evo m.2

Before the 3070 I had a gtx 1660 and I had in valorant 120 fps and in fortnite 60 and again, with big drops.

Ryzen and RAM/FABRIC Speed is a HUGE factor in Ryzen performance, especially in the early years of Ryzen.

The Ryzen Fabric is tied to Ram speed, slower ram = slower fabric = slower CPU performance and worse gaming performance.

Your limiting the RTX3070 by a few factors all tied together, which you still saw with your GTX1060 being likely RAM/Fabric bottlenecked as well.

Spoiler

Getting XMP 3200Mhz to work would be a big deal for your currently owned KIT, its not just speed, but timings, XMP is TUNED somewhat, stock 2666Mhz without XMP is going to have horrible performance at whatever timings the board gave it while training memory before the boot process.

Heaps of video's have been made by mainstream reviewers about slower ram on Ryzen / faster ram on Ryzen. I'd suss them if curious.

MinFPS (The Drops you experience) will be greatly improved when its all balanced properly with faster ram/fabric speeds.

The CPU can only do so much as is, but your RAM/Fabric situation makes it worse limiting performance further.

While the ram can have some influence I think the more fundamental problem is that CPU generation is relatively weak by current standards. I think if you can move to a 3600 or higher CPU that could help, and may also help the ram run at its rated XMP speed as the memory controller improved between those gens.

 

Assuming the ram is 2x16GB and of similar age to the rest of the system, I'd guess it is dual rank so would be a harder load for the memory controller too.

I don't know why people still mix Intel/nVidia and AMD in this day and age where they are actually at war and building system specific features that are not interchangeable. You bought a good AMD processor, buy a good AMD video card, not an inferior nVidia overhyped and overpriced GPU.

 

But the first thing striking me is you want to run brand new hardware on an antique PSU. 600W is sooo 2012 Under Powered.

When you buy a PSU you mark up 2x to 3x the total Watt consumption to account for Peak Power Demand.

 

But for people who think 165fps is bad, how do I explain anything ?

yeap 3600 has zero issues with a 3070, but a *checks notes* 2600? Oof... 

btw here in europe it seems a 5600/x is much cheaper than a 3600 now (for some reason)  so 5600 would be a much better upgraded (if applicable)

Well...the 3600 isn't even enough for my 3060 in all games. Heavily cpu-bound titles like BF2042 (due to the high player-count) can reveal a slight bottleneck and my 3060 will only be at 90%, which should be worse for the 3070. I mean I don't play that anymore, so it doesn't matter to me. And basically all other titles I play don't see any bottlenecking at all, but I just wanted to share that it is close. 

 

Just saying so OP doesn't buy a used super cheap 3600 and then wonders. Definitely go for the 5600 due to the amazing prices anyways.

there are surely a few cpu bound games (like msfs afaik) which are cpu bound, but overall for most games there arent any issues... Warzone was close but not even that was cpu bound (got like 150-190fps at 1080p, 1440p wasn't a lot worse, 160 max or so)

 

and yeah thats what im saying a 5600 would be better obviously.
