It is difficult to compare Ryzen 7 with Core i7, as they are not exactly Apple to Apple. It is just like you won't compare Toyota Corolla with Honda Civic for just the performance.

I used HP Pavilion Gaming Desktop to measure as it is the only desktop in the market that offer both choices. To compare, I align the configuration as close as possible between Ryzen 7 with Core i7. For Core i7 (10700), HP is selling it for $1,050. For Ryzen 7 (3700X), HP is selling it for $980. Based on publicly available benchmark data, Core i7-10700 has the benchmark of 17591 and Ryzen 7-3700X is 22740. So using Ryzen 7 will have almost 30% improvement in benchmark and yet $70 cheaper. So number-wise, it is a no brainer to picky Ryzen 7 over Core i7.

But does that mean you have to pick Ryzen 7 over Core i7? Not necessary. FWIW - the availability of Core i7 is overwhelming over Ryzen 7, which includes any used and refurnished computers (desktop/laptops). So with a performance trade-off, you may be able to save big on i7 over Ryzen 7.
