| Captain_Yuri said: The videos you have listed aren't very good examples of the issue at hand. I'll admit, partially would be my fault since I should have actually listed the videos. Yes Ray Tracing is primarily GPU bound but DF has noticed that many aspects are in fact CPU bound to the point where a 3600 can't hold 60fps. Of course, the fix is just to turn down a couple RT settings and a 3000 series can go well above 60FPS but with a 5800X3D, that shouldn't be needed. There is no doubt that 3600 can get over 60fps in many modern titles, especially without RT. But the point I am trying to make is when we really start pushing the CPU with next generation settings, that is where it starts to struggle. Now I am not saying it's a bad CPU, this problem is also happening with old Intel CPUs like 10th gen and such. Because the problem with the modern PC industry is the GPUs generational jumps are far exceeding CPUs to the point where a lot of the CPUs are becoming the bottleneck even at higher resolutions and a lot of it has to do with ST and the games don't seem to scale up much more than 8 cores. Also you are acting like a 5800X3D can't do multitasking when infact, a 8 core 16 threaded CPU can do very well at multitasking. There are certainly tasks that having more cores than that would help in. I bought my 5950x because I need to use virtual machines for work and I like to test configs before deploying them. That is something that having more cores over ST will help with. But even then, you can deploy 5-6 virtual machines before a 5800X3D would start to struggle. For me, it's not so much that 3000 series are obsolete but more so that 5000 series is simply a better pairing and will also be cheap when Ryzen 7000/RTX 4000 comes out. Anyway I think it's time to move on since my road trip is coming up so I'll agree to disagree. |
I guess you didn't watch the video?
Even digital foundry shows they went from 38fps to 58fps by dropping RT ray tracing resolution from very high to high, which again proves my prior point that Ray Tracing is GPU bound, not CPU.
They also state you get an extra 20% more performance by dropping Ray Tracing geometry from very high to high.
These are GPU bound settings, not CPU.
Now when they are comparing Ray Tracing object draw distance, that has a CPU impact due to the extra CPU load in regards to A.I and scripting, the others really don't.
And Digital Foundry also state that CPU's with "Greater core counts and speed" should just dial it up. That would include the 3900/3950X.
But if you turn all the Ray Tracing settings to very high and push the game to 4k, then it doesn't matter if you have a 3600 or 5800X3D, you are going to be GPU bound first and foremost.
It's about achieving "good enough" performance where it is acceptable... And one game being outlier isn't a trend that is industry wide either, especially when I threw a ton of games out into the open in my prior post to prove that point.

Far from it. But the 3900/3950/5900/5950X leave the 5800X3D in the dirt as far as multitasking is concerned. You can double your performance.
I don't disagree that the 5000 series is a better buy, if your motherboard supports it, I wouldn't even consider the 3000 series if that support exists, but the point is to get a performance improvement for the lowest dollar cost in the short and long term, the 5800X3D isn't always going to be the right answer.
| JEMC said: Well, it doesn't happen often but I'll have to correct you. It looks like they learned from the X570 chipset and have gone back to ASMedia to develop the new ones: https://www.tomshardware.com/news/amds-multi-chiplet-x670-x670e-strategy Here's how AMD’s new chipset architecture works. The base chiplet for X670 and X670E is known as the Promontory 21 (PROM21) chipset, which is built by 3rd party supplier ASMedia. One of these chips comes in a 19x19mm FCBGA package featuring a maximum power rating of 7W. |
That is why I said "correct me if I am wrong" because I was honestly clueless and didn't have the time to look it up before I made the claim. :P
But thank you for the clarification.
I think ASMedia are the better option the x570 seems to be a solid chipset.
