In the Geekbench benchmark database, a test of a certain platform with a 48-core AMD Epyc 7643 processor, a representative of the Milan line, has appeared. And this CPU performed very well, earning 5850 points in a single-threaded test (frequency – 2.3-3.6 GHz, maximum with all working cores – 3.45 GHz), and in a multi-threaded test – 121,080 points! True, the amount of RAM turned out to be decent – 384 GB.
For comparison, a platform with two 28-core Xeon Platinum 8276 CPUs and 192 GB of RAM in the same Geekbench earned 4913 points in a single-threaded test and 112,457 points in a multi-threaded one. But even if we level the memory size to the same 384 GB, Intel still loses: two 28-core Xeon Platinum 8280 scores 5048 points in a single-threaded test and 117,171 points in a multi-threaded one.
And now some calculations. TDP and cost of one Xeon Platinum 8280 – 205 W and 10,000 dollars, respectively. TDP Epyc 7643 – 225W The price of the new AMD product is still unknown, but the current 48-core model – AMD Epyc 7642 – costs about $ 7,700. Even if we assume that the Epyc 7643 will cost one and a half times the current model, it will still be half the price of the Xeon Platinum 8280, consume half the energy, and at the same time provide even greater performance.
