There are some differences, but real world applications, especially in the gaming space, are minuscule. You do almost touch on another important point; it’s hard to get benchmarks because you’re not going to find a processor that was made for both. Basically a single gen of intel is all we get. FWIW that gen showed a roughly 5% performance on a typical game, and 10% on a known memory intensive game. That’s 3 frames at 60fps, or ~7 frames at 144, and this assumes you actually need that last bit of performance.
