Notes

Everything has been tested from the ground-up to provide consistent results across the processors.

Ryzen 3rd Gen were tested on an Asus X570 Crosshair VIII motherboard that provides PCIe 4 continuity across the platform.

Meanwhile, Ryzen 7 2700X and Ryzen 7 1800X, the champion AM4 processors of their generation, are run on an MSI X470 board, befitting how readers are likely to use them. Each processor was run with its correct memory speed.

We've sought to compare AMD's AM4 socket to Intel's LGA 1151 - the two key mainstream solutions on the market today - and have therefore run a trio of Core processors on a Z390 motherboard.

The reasons for Core i9-9900K and Core i7-9700K are clear: they are the price competitors to AMD's reviewed 3000-series duo, and we've also included an 8th Gen part for older comparisons. We've run each Intel processor at its correct per-bin speeds, which for the Core i9-9900K means a higher power target than 95W.

Though AMD shoehorns in a 12C/24T processor in the mainstream platform, we believe it fair not to include Ryzen Threadripper and Core-X at this juncture. Those comparisons are most apt when the Ryzen 9 3950X surfaces in September.

Last but not least, the use of an Nvidia GeForce RTX 2080 Ti Founders Edition card ought to reveal any low-resolution gaming weaknesses in any processor.
