XCC每个Tile的整合IP加速单元,都能支持QAT、DLB、IAA和DSA,所以每种设备最多都是4个;MCC架构的QAT和DLB每插槽最多2个,DSA和IAA只有1个。 写到这里,Intel和AMD(如上图)谁的Chiplet架构更好呢?应该说各有各的优点,感觉AMD的CPU die + I/O die比Intel XCC更灵活一些;而Intel MCC的内存访问、I/O性能一致性...
SemiAnalysis的首席分析师Dylan Patel透露,这次Bug是关于计时问题,根源是产品设计缺陷,主要影响双路、四路型号,6月中旬就已经停止出货了。 Intel四代至强分为三种版本:MCC以为中等数量核心,单芯片设计,最多32核心;XCC意为超多数量核心,四芯片整合封装,36-60个核心;HBM就是在XCC基础上增加了HBM2e高带宽内存,最多64GB。

As you may know, the Uncore Performance Guide is available for Intel's 4th and 5th Gen Xeon Scalable products, but it only covers XCC (Extreme Core Count) models. My question is:Will the Uncore Performance Guide for XCC also apply to MCC (Middle Core Count) products? I look forward...
We’ve seen SKU sheets like the one above ever since the original Xeon Scalable launch, but this one has many extra details that are worth mentioning. To start, the core configuration will either be listed as XCC or MCC. XCC represents CPUs with multiple “tiles” inside, while MCC is a...
Moreover, The 5th Gen Intel Xeon processors come in different die packages to cater to various computing needs. The XCC package offers up to 64 cores, providing the highest performance for the most demanding tasks. With a single monolithic die, the MCC package supports up to 32 cores, balanc...
Intel has launched its 4th Gen Intel Xeon scalable processors (Sapphire Rapids), the Intel Xeon CPU Max Series (Sapphire Rapids HBM), and the Intel Data Center GPU Max Series (Ponte Vecchio). They are purpose-built to improve data center performance, efficiency, security, and capabilities for...
