@mittens02132 Intel and AMD each have their own naming conventions, and their processors each have their own strengths and weaknesses. So it's easiest to first compare CPUs from the same manufacturer and go from there. In general:
Intel: Celeron < Pentium < i3 < i5 < i7
AMD: various A-series < Ryzen 3 < Ryzen 5 < Ryzen 7
However, it's not a perfect comparison for various reasons. Processors keep getting more powerful, so a newer low-end CPU might be stronger than an older mid-range one. A desktop i5 is more powerful than most laptop i7 models, and not all i5 models (for example) are created equal.
There is a lot of info about processors and their capabilities, but very little of it is relevant to you. The most important factor in determining how well a given computer will run Sims 4 is the graphics card, of course provided the other components are adequate. In your price range, you're looking at getting a graphics chip that's integrated into the processor. So it's best to choose the processor with the fastest graphics chip.
Luckily, this is fairly straightforward. The Intel CPUs that come in the laptops in your price range have at best an Intel UHD 620 graphics chip. The AMD Ryzen 5 2500U and 3500U have a Vega 8 graphics chip. The Vega 8 is almost 90% faster in gaming than the UHD 620, although it does vary somewhat by game. The gap in Sims 4, at least the base game, is smaller than 90%, but the gap is still significant enough to make this an easy call.
