Where do you get games use 4 cores? Games in fact can run off of only 1-2 cores. But the higher cores you have and the more threads each core handle is the determining factor. The Problem with AMD is their gaming performance lacks in all tests. In fact a Ryzen 9-3950x PBO gets 129 FPS, where as an i7-9700K @ 5.1 gets 141 FPS. At base clocks though, Ryzen 9 3900x PBO gets 128 and i7-9700k 127. And I’ve never seen my i7-9700k run at base clock speed. When you open a game the i7 auto boosts itself (no overclocking done) to 5.1. So yea Intel beats the highest AMD processor in gaming. AMD is great for multitasking, Intel for gaming.
now if you’re on a budget get AMD, if not get Intel hands down. Just the 13 FPS in a game is like taking away a click or two here and there.
Have you ever played Ghost Recon Wildlands on a 4 core CPU? Or Shadow of the Tomb Raider? Or Battlefield V? Assassin's Creed Osyssey? These are just a FEW of the games that run far better on a 6c/12t processor than on a 4 core processor, with or without hyperthreading.
The claim of Intel being better at gaming is indeed true, but if you have ever seen a single unbiased review in your entire life, you'll know that Intel is better in VERY specific scenarios, and with a 120 or even 144 Hz monitor, you'll never tell the difference between an Intel chip and an AMD chip, let alone on a 60 Hz monitor. The fact of the matter is that the numbers you are claiming for showing Intel's superiority are very likely to be extremely biased - consider the very obvious bias that the 3950X is obviously running at its out of the box configuration, while the i7 has been overclocked on a very high-end liquid cooler to reach that 5.1 GHz figure. Along with that obvious difference, there's also the fact that the 3950X is a
16 core 32 thread processor while the i7 is a measly 8 core 8 thread. If you think comparing these two chips (with one being a $750 chip and the other being a $400 chip) is a fair comparison, you need help. The 3950X is obviously not aimed at gamers anyway.
My point being, any reasonable person knows that Intel being better at gaming is now only a thing that people say, but no one actually believes Intel is better for pretty much anything, except if you want to play less demanding eSports games with a 240 Hz monitor and an overkill GPU.
And also, an i3 is absolutely not a workstation CPU - it's the exact opposite. Do you even know what a workstation means? It doesn't mean a PC on which you do office stuff - a workstation PC is supposed to have high-end hardware for demanding things like video editing, animation, etc. An i3 is an entry-level gaming or office PC CPU, not a workstation CPU.
