Memory bus width != CPU Bitness

Those two numbers describe totally different things.

For GPUs the bitness number is usually used to describe the width of the memory bus that is how much data can be “transported” concurrently.

For CPUs the bitness describes the size of the data that can be processed at any given time. With AVX, CPUs can handle data vectors that are up to 512-bit long.

GPUs are in fact 64-bit processing units, the largest data type they are designed to handle are 64-bit double precision floating-point numbers.

The 14700K is not really a refresh of the 13700K, it has an additional 4 E-Cores, it really is the only improved CPU among the K SKUs on the 14th gen.

So if OP uses multi-threaded applications a lot, the additional E-Cores on the 14700K might be worth the difference in costs. In gaming, besides the 2 APO games, 13700K and 14700K perform more or less the same, the difference can be gained by slightly oc’ing the 13700K.

Second gen AMD HW ray-tracing still has a worse performance impact than Intel first gen HW ray-tracing. No need to talk about Nvidia here, as they are miles ahead. Either AMD is not willing to expend more resources on RT or they aren’t able to improve performance.
