What is the difference between the Intel 60-core Xeon Phi processor and the CPU used by ordinary PCs

According to Intel, Xeon Phi is not an ordinary processor, but a co-processor, which means that Xeon Phi is a co-processor that helps the CPU share the amount of calculation like a graphics card. For the coprocessor, 60 cores are not too much. The GT640M LE that my laptop is equipped with has 384 CUDA cores. Of course, the capacity cannot be compared with Xeon Phi. So if the home computer is a co-processor, the 60 core actually already has it. If the CPU has 60 cores, it does not seem to be in the short term. After all, home computers are not suitable for highly parallel computing, and the number of processor cores will not be quickly increased to this number. Intel Xeon ProcessorXeon Phi first came from a project called Larrabee from Intel, and it was aimed at the popular GPGPU at the time, especially CUDA. Although the x86 single processor has very powerful computing power, it is expensive to build. It is very uneconomical for tasks that have a huge amount of calculation, such as scientific computing, but can be split into many parts for parallel computing. Larrabee's idea is similar to parallel computing solutions such as CUDA, which uses a large number of relatively weak computing power processors to perform parallel tasks.Compared with ordinary x86 CPUs, the biggest difference is that Xeon Phi exists as a coprocessor, that is, such machines generally need to be equipped with another Xeon, such as these sold by SGI (SGI with Intel Xeon Phi Coprocessors). However, Intel's manual claims that Xeon Phi can be found by IP addressing and can run Linux systems independently, which is different from ordinary coprocessors. In addition, Xeon Phi is connected through the PCI-e interface.The instruction set used by Xeon Phi is also different from that of ordinary x86 processors. There is an article saying that Xeon Phi is not compatible with x64 in binary code, but now Xeon Phi also claims to be able to run Linux, and it may be partially compatible. Xeon Phi has 61 cores, each of which has a low clock speed of 1.2GHz, which is lower than the low-voltage version of the CPU used in notebooks. Each core has 4 threads. Xeon Phi's floating-point computing power is also much stronger than ordinary CPUs, claiming to be up to 1.2 TeraFLOPS.Xeon has a more powerful memory controller: Xeon processors definitely support ECC error correction in memory controllers, and higher-end processors can also support ECC REG; if you think Xeon (E5 or higher) can support three Channel, four-channel memory can also be particularly similar, then the advanced i7 \ i9 processors of the X79 / X99 / X299 platform also support this function (because they are equivalent to E5);More powerful PCI-E Controller: In fact, this is more understood as the number of integrated PCI-E channels (especially E5 and above), but home LGA2011 / 2066 processors also have so many channels (because they are equal to E5 );Multiple operation. Xeon specific series can support dual-channel (two CPUs are placed on the same motherboard inserted into the dual-CPU socket), four-channel or even 8-channel operation, and household product lines do not support this function. This E5-2xxx (support dual Channel), E5-4xxx (support four channels) \ E7-8xxx (support eight channels).
