input on CPU choice on new PC build
I know there are threads that address this in some measure but I am building a new pc for the office and I am trying to choose between AMD and Intel for CPU.
I was planning on using this LINK but came across this LINK AMD chip on sale. It looks like a beast and for a great price........ but I would have to buy a graphics card. What do you think? Is a beast like the AMD preferred?
I am planning a M.2 SSD drive as well as 16gb of Ram. I am going to buy tomorrow and then saw this sale......not sure which direction to go.

What ever your decision, never buy Celeron - it will bottle neck.
AMD was always better with mathematical processing on lower power consumption. I don't know about the new Ryzen though. I used AMD in the past for programming purposes.
Intel is better if you don't have a dedicated Graphics Card and don't mind about power consumption. In the past Intel was always more stable.
As a user that used both AMD and Intel, I would recommend going with Intel. The new Ryzen could maybe be competition. I ask myself one question, why the $130 discount on Ryzen. This always display a huge red flag. But then, who knows?

CPU benchmarks => https://browser.geekbench.com/processor-benchmarks shows Intel having 46 models that are faster than the fastest AMD Ryzen.
AMD Ryzen 7 2700X has a benchmark of 4821 that is 22 % slower than 6167 for an Intel Core i7-8086K so a computation task of 10 minutes on the Intel Core i7-8086K takes 12.8 minutes on the AMD Ryzen 7 2700X

A fairer comparison is Ryzen 7 2700X 3.7 GHz (4820) vs i7-8700K 3.7 GHz (5881); about 18% difference. The 2700X is the successor to the 1800X; which is why the 1800X would be discounted.

Thanks for the input. I went with the i5 8400, 2.8 Ghz base - 4Ghz Turbo. Seems to be more than capable to handle Logos.

I agree (along with an SSD!).

I went with a M.2. Incredible read/write speed. Dave, you seem to know a bit about pc’s. Given my processor would you add a GPU or would it not be worth it? If you would add one, what specs?

It's not a 3D app, so it isn't necessary for Logos. With an i5 on my laptop (and on previous ones), I haven't noticed any difference when I forced Logos to use the GPU. So don't get a GPU unless you are into serious gaming or graphics work.

This is not true. At least “was always better” wasn’t true. What’s the time period you’re talking about?
Notable factors:
-
Recent advance in 10 nm process in AMD CPU makes it having better power consumption, but this isn’t true until very recently, like a year ago. In fact, AMD was pressing towards 7 nm because they were trying to catch up with Intel in 2018 IIRC. But unfortunately Intel’s 10 nm process, supposed to be out a lot earlier, then on 2018, was further delayed to 2019. (People define the nm processes differently, Intel’s 10 nm is more like AMD/Samsung/Qualcomm’s 7 nm.)
-
Since you’re talking about “mathematical processing”, these are relevant too:
- Intel’s vectorization unit is much wider, e.g. currently AVX512 is 512 bit wide, and for some CPU there’s 2 such units per core, but AMD only has 256 bit IIRC. This translate into more FLOPS, e.g. 512 comparing to 256 will be double amount of FLOPS.
- Intel’s compiler, MKL library, etc.: these will generally gives a better performance, sometimes much better performance on Intel’s CPU comparing to not using this and is with AMD (e.g. FFTW with GNU compiler on AMD.)
