Specifically to the Roman processor, that is, the separation of CPU and IO core, CPU part has 8 8 core modules, a total of 64 cores, IO core is manufactured by 14nm process, integrated with DDR memory controller and other chips.
The 64-core 128-threaded Roman processor will undoubtedly be the king of the new generation of processors in multithreading performance, but how often will the processors be when the number of cores increases? It is also important that this issue affects the single-core performance of AMD EPYC and even Ryzen Ryron processors.
Recently, there are 32-core, 64-thread QS chip test data on SiSoftware. It shows that the baseline frequency of 64-core Xiaolong processor is 1.4 GHz, accelerating 2.2 GHz, which is very low.
However, it is reported that the actual frequency of AMD 64-core processors is not so low. The base frequency will reach 2.35 GHz and the acceleration frequency will reach 3.2 GHz. The acceleration frequency is similar to that of the existing EPYC 7601 32 core processors, and the base frequency will be higher.
What does this frequency mean? Although the basic and acceleration frequencies are still very low compared with desktop processors, you should know that this is a 64-core 128-threaded super-core processor. AMD's 32-core processor's TDP is 180W at present, while the second-generation EPYC's TDP has increased by 50% to 240W, but it has 100% more core, and the basic frequency is higher, so the energy efficiency of the new-generation 7Nm processor is very high.
Not to mention the comparison with AMD, compared with Intel's 56-core processors, although the frequency of 2.6 to 3.8 GHz is much higher, the power consumption of TDP is 400W, much higher than that of 240W Roman processors. It can be seen that the role of the 7Nm process on AMD 64 processors is great.
