Choosing the right CPU

[anMori]

Hi!

 

I´m building myself a high end machine primarely for professional 3D work and secundary gaming for which I´ve narrowed down my choice for a suitable CPU on the following cores:

 

Intel Core i7-8700K (6 x 3.70 GHz / 4.70 GHz)

Intel Core i7-7820X (8 x 3.60 GHz / 4.30 GHz)

AMD Ryzen 7 1800X (8 x 3.60 GHz / 4.00 GHz)

 

Potentially also an AMD Ryzen Threadripper 1920X 12x 3.50GHz 

 

I´ve done my homework and looked up various arguments regarding cores/compatibility/price and the i7-8700K seems to be a good bet being intels latest relase however it´d be a great help to hear more opinions on this.

Especially when it comes to:

 

-Is Coffee lake that good to justify a 8700K instead of a 7820X? 

 

-Higher clock speeds = good for gaming and number of cores = great for a multi tasking oriented work environment (many programs active at the same time) 

 

-If your programs only support 4 cores but you run multiple at the same time, do they still benefit from an 8 core in terms of being able to be split between them?

 

-Intel/AMD compatibility experiences by fellow 3D guys

 

-AMD experiences so far with the new ryzen lineup

 

Looking forward to any input you can give me!

1. The 8700k runs really hot, if you're fine with that the ipc is slightly better than the 7000 series, but more cores will be far more beneficial than the small ipc improvement where those cores are put to use.

2. higher clock speed*ipc=good for gaming, but otherwise you've got it

3.yeah, works out something like that

4&5. I'm not the droid you're looking for

@CyracusThanks for the reply! Good to know it heats up quite a bit. I´ll consider water cooling in that case. Kinda tempted to go for the 8700 right now as intel is the safest bet in terms on compatibility and 6 cores also seem sufficient for multi tasking.  

 

Got a weird gut feeling about AMD but I´m happily proven wrong in that matter.

 

Would that make sense?

 I have a good feeling about AMD, Intel's been messin up lately. I reckon the coffee lake we got was Intels backup plan
