The first Puget Supermicro X13 performance benchmarks for the Intel Xeon 3465X 28-core CPU reveal that it is barely faster than the 13900K. This is concerning since the 3465X is a $2900 USD CPU while the 13900K can be bought for around $570 USD.
Intel Xeon 3465X Vs 13900K
The Intel Xeon 3465X has 28 cores and all of them are performance cores. There is no hybrid architecture so no efficiency cores. It also has 56 threads, a base clock speed of 2.5 GHz, and a boost clock speed of 4.8 GHz. The 13900K is the top-tier consumer CPU that Intel is offering right now. It has 24 cores in total but 8 of them are performance cores while 16 are efficiency cores. It has 32 threads and can boot to 5.8 GHz.
Testing both of these CPUs in Cinebench R23, the Xeon chip has a lead of 11452 which is not much keeping in mind that it has 20 more performance cores and is $2330 USD more expensive. You can check out the performance difference in the benchmark below:

It is worth mentioning that both CPUs consume more than 300W. It is not surprising that the Intel Xeon 3465X loses to the AMD Milan chip with 64 cores but while the Intel CPU was running at 374W the AMD chip only took up 287W.
It is also worth mentioning here that Puget limits power to their 13900K. By default, boards run the i9 CPU at more than 300W which gets the CPU an R23 score of more than 40,000, with decent cooling. So the 3465X is not really all that fast at more than 300W.
