It won't be more than a week or two before AMD will unleash its new Ryzen 3000 processors and the X570 platform. We're bound to see some accidental leaks beforehand I guess. The first one starts today as a Ryzen 7 3800X has been spotted. 

The eight core Ryzen 7 3800X  CPU shows a base clock of 3.8 GHz and a boost of up to 4.5 GHz. From the looks of things, memory was not configured right, at only 2133 MHz - nonetheless, the results are impressive. The test platform had an 3800X paired with a X470 motherboard and achieved a single-core score of 5406, the generic score was 34059 points. If you give the  Core i9 9900K with DDR4 set at the same speed all equal then it scores about 1% better in single-threaded performance (has a higher boost of 5.0 GHz), however, in multiple threads, there is a win with close to 5% in favor of AMD. Digging a little further shows a 9900K with ddr4-2666 memory to performs more than 14% better on a single thread and half a percent better in the multi-core test.

These tests, of course, and Geekbench in general, say very little, but do show an indication of what we can expect. 

AMD Ryzen 7 3800X surfaces in Geekbench, performs roughly similar to Core i9 9900K
