Which one should I BUY ??? AMD RYZEN THREADRIPPER or INTEL CORE i9-7900X ??

yeah thats true.. but according to previous processors.. AMD was not up to the mark... thats why I'm confused between Intel and AMD

Ryzen is not FX. It nearly matches Skylake-E IPC clock for clock (at most 5-10% behind) and the cores utilise a similiar SMT design as Intel.

With Threadripper, you will get more cores for the same price. 16C 32T compared to 10C 20T. And you will also get a higher stock clock of 3.4 GHz compared to 2.9 GHz.

I also assume you do not want to overclock as you want the most reliable performance. For reliability, both CPUs are exceedingly good, at stock.

The only downside is that Ryzen is usually RAM limited and cannot reach high frequencies in excess of 3200 MHz. However, you will be hard pressed to even fully utilise the bandwidth of Quad Channel 2400 MHz RAM!

Get the Threadripper 1950X. And pair it with a good Zenith Extreme board and 4 sticks of FlareX 3200/3466 or Trident Z 3200c14.

And then pair it with a GTX 1080 Ti or an OCed RX Vega 64. Currently the best gaming setup for 4K.

The 1950X has 60% more cores than the 7900X, and it doesn't even beat it by 30%, on average. In some tasks, the 7900X comes on top, especially anything that makes use of AVX-512.

They cost the same. Well actually the 7900x costs more despite its performance deficit. So what...in your opinion, is an acceptable loss percentage for a processor that costs $100(10%) more than the competition? 25%? 20? Are you suggesting people should pay more for less because the slower product has fewer cores?

Ugh the misinformation here is mind-blowing.

PCI-E Lanes
Threadripper has 64 lanes and the i9-7900x has 44 via the CPU itself. But the x299 Chipset (Intel) provides another 24 PCI-E lanes.

Winner: Intel

Base Clock Speeds
Someone here innacurately stated that the i9-7900x base clock is 2.9GHz. It is actually 3.3GHz.

Overclocking
The i9-7900x is an overclocking monster (just cool it well which isn't THAT hard - I'll get to that later). It will OC past Threadripper all day long. Higher clock speeds are good for gaming. More cores are good for multitasking and multi-threaded workloads (i.e. Editing).

Adobe Premier

The caveat to the above in your particular use case is that Adobe Premier actually performs better on Skylake-X than Threadripper, even though it has less cores. Premier prefers clock speeds vs. threads. This could change in a future update to the software of course, so there's no good answer here.

Cooling
There is A LOT of talk about this. I currently own an i9-7900x. I was going to go with Threadripper but my use case is gaming/streaming so the higher clock speeds for gaming and the extra cores for streaming made this CPU the perfect fit for me. That being said, I took all necessary precautions to ensure I cooled it properly. I bought my CPU from siliconlottery.com so it came delidded and the shitty TIM (Thermal Interface Material) provided by Intel was replaced with liquid metal. Buying from Silicon Lottery was the SAME price as buying the CPU from Newegg. I paid $969 + shipping. The only difference is your 3 year warranty from Intel is void by delidding but SL gives you a 1 year warranty. Honestly, I have NEVER had to replace a CPU so I'm not concerned. In addition to delidding it, I used Thermal Grizzly Kryonaut thermal paste and an Alphacool Eisbaer 420mm AIO. I currently have my i9-7900x OC'ed to 4.8ghz and with Prime95 for 1 hour, temps reached 69C. When gaming at 1440p w/ everything at ultra and streaming at 1080p60, 6k bit rate, temps never go above 53C. My previous i7-4930k OC'ed to 4.5Ghz would reach 55C while gaming and 65C while gaming/streaming. So in conclusion, proper planning eliminates the cooling issues for literally no extra cost. You would be buying a good AIO cooler anyway for Threadripper (Seriously, don't cheap out on cooling your ONE THOUSAND DOLLAR PROCESSOR).

Also, for those interested, my BIOS settings for my OC are:
XMP profile for RAM (32GB G.Skill TridentZ RGB) 14-14-14-34 3200Mhz
Baseclock: 100
Voltage: 1.225
AVX: -3
AVX 512: -5

Blanket Statements
Some dude here posted "only buy 7900x if you refuse to buy AMD". Bro, shut up. When choosing parts that cost $1,000 USD, there are a lot of things that should influence your decision. I am brand agnostic but the Intel offering didn't cost me anymore and is perfect for what I wanted to do. If I was editing in Blender all day, I would go Threadripper - no question. It's all about use case.
