I have been looking for new hardware for a while. I pre-ordered the 2080Ti, great GPU. Not great for the money, but even if it is just a 20% performance gain, its enough for me as I mainly want it for VR gaming and to play around with DXR.
But I keep being unsure how much to spend on the rest of the computer. Right now I have a 6700K, its about 3 years old now and I am pretty sure its quite the bottle neck for this monster GPU.
I found this article which makes some good points about what CPUs to get... but it seems to argue mainly about value for the money. Not so much about what is gained by going for the pricier CPUs. https://www.pcgamesn.com/best-cpu-for-gaming-2019
This article seems to turn the other article on its head: https://www.pcgamer.com/best-cpu-for-gaming/
It puts the 9900K at the top... the 9900K is the CPU I figured to be pretty perfect for my GPU. First I was looking at the Threadripper CPUs, so... the 9900K is less pricey than that. I use my PC for much more than gaming though.
I play around with some hobby game development, general software development, web development, machine learning with TensorFlow, make videos of some games and game development tests and experiments and of course gaming which includes PC VR gaming and development. So I am not only looking for the gaming benefits. Which is why I also first considered the Threadripper series. But one of the main reasons I have not even considered AMD the last many years, is that Intel just seems way better when it comes to power efficiency. Looking at Threadripper, they seem very power hungry. I am not sure if having more cores means they will be better at scaling up and down in certain situations? Or does f.ex. the 250W of the 2990WX mean its constantly using way more power than a 95W 9900K?
So... it seems to come down to these choices:
9900K, 2700X, 9700K, 2920X or 2950X.
The 2700X is the cheapest. It actually provides both 8 cores and 16 threads unlike the 9700K. The 9700K has a higher clock rate. 2700X is 105W while the 9700K and 9900K both are at 95W. The 2700X has 20MB cache while the Intel ones have 16MB. Also the AMD is 12nm while Intel is 14nm. But that does not seem to matter much, since the AMD one uses more power and has a lower clock-rate anyway?
2920X is about 150 dollars more than the 9900K. It seems to have a lot of pros and cons... 12 cores, 24 threads and 3 levels of cache. One level having 32MB, another with 6MB and a third with... is it around 1MB or 1GB? Seems... unreal to have 1GB of cache? Also not sure what it means to have all these levels of cache? Does it help with the power consumption in any way?
So I am interested in these higher core count CPUs, but not if it means the whole PC will just generally throw power out the window even if I am just looking at Facebook or watching Youtube. I mean, I am mostly happy with even what my 6700K provides, but sometimes I do feel the rig wants to do more, but the CPU is being in the way. Now and then it also begins to cool at a much higher level than I experienced previously, which I am pretty sure is because the CPU is forced to run at full usage to keep up with the GPU... and probably still failing.
Which also brings me to another topic. Water cooling? Is it noisy? I see many pages suggest regular fans if you do not plan to over-clock, and I generally do not over-clock. I also know that it varies a lot how much noise different fans can generate... but is water cooling generally more or less silent?
Another factor to add to the list, is what you get with these CPUs, as it seems AMD and Intel CPUs might not provide the same features from their motherboards. AMD seems to have more... not sure if it is RAM or hard disk features. I saw some video from Linus Tech Tips about that.
Oh... and another thing to add. This CPU benchmark list:
My current CPU is at 11109 points.
Compared to: 2950X at 25458 points 2920X at 21929 points 9900K at 20166 points 2700X at 17276 points 9700K at 17254 points
Prices at the store I am looking at are: 2950X for 1090 dollars or 23,36 points per dollar 2920X for 800 dollars or 27,41 points per dollar 9900K for 650 dollars or 30,95 points per dollar 9700K for 515 dollars or 33,50 points per dollar 2700X for 410 dollars or 42,13 points per dollar
So... looking at it only like this, it sure seems the 2700X is the best value for the money.
Annoying, seems the forum ignores my line breaks for readability with the benchmark and price comparisons.
