Listings for the Core i7-10510U and Core i5-10210U have appeared on Geekbench, although their scores should be no cause of worry for AMD. The chips are outgunned by not only the Ryzen 7 3700U and Ryzen 5 3500U but also the current crop of Intel Core i U series processors. Oddly, these 10th generation CPUs do not appear to be based on Intel's Ice Lake architecture either.
