Grab a GN Coaster Pack & support all our testing efforts! Our review & benchmarks of the Intel Core i9-13900K CPU includes testing vs. the AMD Ryzen 9 7950X, R9 7900X, Intel i9-12900K, and more. The 13900K CPU is brand new from Intel, but sockets in both Z690 (backwards compatible) and the new Z790 boards -- though there shouldn’t be much difference between features. The 13900K can run with DDR4 or DDR5 and will likely be the last true consumer platform on DDR4. AMD AM5 is already fully committed to DDR5.

This error doesn't change any of our conclusions nor does it change that the CPU does d
