Limitations due to die size and power consumption since Intel Xeon is still on the ye olde 14nm++ process.
Also since Xeon dies are monolithic, unlike AMDs chiplet design, means that increasing the size of certain components on the die, like cache for example, increases the risk of defects wich reduces the yields, making them unprofitable.
- rbanffy 6y agoTrue, but the ARM ones have just 32MB for up to 80 threads. I wonder if we could get numbers for L3 misses and cycles spent waiting for main memory under realistic workloads.
- dragontamer 6y agoThat information changes with every application. Literally every single program in the world has its own cache characteristics. I suggest learning to read performance counters, so that you can get information like this yourself! L3 cache is a bit difficult for AMD processors (because many cores share the L3 cache), but L2 cache is pretty easy to work with and profile. General memory-reads / memory latency is pretty easy to read with various performance counters. Given the amount of latency, you can sorta guess if its in L3 or in DDR4.
- greggyb 6y agoFYI, 'ye olde' is actually using the letter 'y' to represent an Old English 'thorn' character. The thorn character represents the 'th' sound. Printing presses gained prominence in non-English speaking regions earlier than in English speaking regions. The 'y' was substituted for the 'thorn' due to some amount of similarity in shape. Thus, 'ye olde' would be pronounced 'the old'. 'Ye' is just a different form of 'the' from a time when 'y' represented 'th'. So, 'the ye olde' would be read as 'the the olde'.
