Thus in any memory-intensive operation and even forgetting clock speed and thermal throttling, the 2019 iMac 5K always has an edge with its CPU cores getting faster access to memory (also, the iMac is not subject to thermal throttling and has a higher base clock speed). The 2019 MacBook Pro tests as nearly identical to the 2018 MacBook Pro.īoth the 20 MacBook Pro have about 17% less usable memory bandwidth than the 2019 iMac 5K.

With only 8 CPU cores it is not likely to be an issue and not much with 12 cores. And if disk I/o is involved then memory bandwidth falls by the wayside. But many applications require only modest bandwidth, since a great deal of computation is done relative to memory access. Does memory bandwidth matter for real world applications?įor memory intensive computations, memory bandwidth can have a measurable effect on performance. Memory bandwidth is especially important for more CPUs and/or fast ones because it can constrain how quickly data can be accessed by each CPU core. These figures represent what is possible with sustained memory access for 10+ minutes. This test in effect forces the effects to be seen of both thermal throttling (extended intensive CPU usage), and the loss of Intel Turbo Boost (all CPU cores maxed-out). Not to be confused with memory or CPU specifications-this is the real deal, what an application actually has available to it. This page uses the mt stress command of diglloydTools MemoryTester to evaluate available real-world memory bandwidth by a real application.
