We typically don't recommend buying previous-gen chips, but all three of these chips are available at (or near) all-time low pricing while we're in the unforgiving grip of a silicon shortage. That makes them solid alternatives if you're looking to upgrade a current system, or even build out a new platform with previous-gen gear.
For comparison, both the current-gen eight-core AMD Ryzen 7 5800X and the eight-core Intel Core i7-11700K weigh in at $399 when you can find them in stock near MSRP, meaning that the three chips in today's Amazon Prime Day deal are ~$150 cheaper for the same number of cores. That means you'll pay roughly $34 per core for the previous-gen chips while the more modern chips weigh in at $50 per core.
Naturally, the previous-gen eight-core chips aren't as fast as the newer models, but you can reference our CPU Benchmark hierarchy for a crystal-clear view of the performance deltas between the newer and older chips. Here's a snippet of how that breaks down for each chip, with the scores in each category being relative to the fastest chip on the market in each category (higher is better):

Intel Core i7-10700K: was $320, now $260 at Amazon (opens in new tab)
The Core i7-10700K's $260 price tag marks a new low for the eight-core 16-thread processor that operates with a 5.1 GHz boost and 3.8 GHz base clock. This chip makes a cost-effective upgrade if you already have a 10th-gen processor, but be sure to check pricing on newer alternatives before pulling the trigger.

Intel Core i7-10700KF: was $301, now $240 at Amazon (opens in new tab)
The Core i7-10700KF's $240 price tag marks a new low for the eight-core 16-thread processor that operates with a 5.1 GHz boost and 3.8 GHz base clock. This model comes without integrated graphics and makes a cost-effective upgrade if you already have a 10th-gen processor, but be sure to check pricing on newer alternatives before pulling the trigger.

AMD Ryzen 7 3700X: was $307, now $279 at Amazon (opens in new tab)
AMD's eight-core 16-thread Ryzen 7 3700X is at near all-time low pricing for Prime Day, marking the only AMD chip we can find with a substantial discount. This chip ticks at 3.8 GHz under heavy load and boosts to 4.6 GHz. It also comes with full support for PCIe 4.0.

Overall, the Core i7-10700K looks to be the better pick based purely on performance alone. However, remember, this chip doesn't come with a bundled cooler, whereas the Ryzen 7 3700X does. Additionally, the Ryzen 7 3700X supports PCIe 4.0 while the 10700K uses the slower PCIe 3.0 spec.

Cinebench R23 is cross-platform testing software that allows you to assess the hardware capabilities of a device such as a computer, tablet, server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant. The test scene contains no less than 2,000 objects and more than 300,000 polygons in total.
