8-Core and 12-Core Mac Pro has eight memory slots. The more interesting 'find' here is that the Apple 48GB memory kit has about 1/3 less memory bandwidth than the OWC 6 X 32GB 192GB memory kit! Moreover, mixed sizes not matched up drop things even more (4 X 8 GB + 2 X 32GB). OWC Memory 1333MHz DDR3 PC3-10600 240 Pin Quad-Core and 6-Core Mac Pro has four memory slots. This should not surprise, given 6-channel memory on the Mac Pro, versus 2-channel memory on the 2019 iMac 5K. But note that the per-core memory bandwidth on the 8-core iMac 5K (16 virtual cores) is about 1.5GB.sec, whereas it is 2.5 GB/sec for the Mac Pro. It joins OWC’s 2GB and 4GB kits for the Mac Pro, which are available for 469 and 974 respectively. The 2019 Mac Pro just stomps the 2019 iMac 5K for memory bandwidth. The memory is manufactured to Apple’s Mac Pro specification, and includes heat spreaders. Tested using the stress command of diglloydTools MemoryTester. But starting at 16 cores, memory bandwidth is more and more of a factor (when all the cores are going full-tilt). 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. $2049 OWC 56.0TB OWC ThunderBay 4 RAID 5 Four-Drive HDD External Stora… in All Other Categoriesĭoes memory bandwidth matter for real world applications?įor memory intensive computations, memory bandwidth can have a measurable effect on performance. For example, the 2019 Mac Pro especially with 16/24/28 CPU cores needs all the bandwidth it can get. 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 5+ 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.

Configurations of 5, 7, 9, 10, and 11 DIMMs are not supported. Mac Pro supports up to 12 DIMMs installed in configurations of 4, 6, 8, or 12 DIMMs. Mac Pro can use either RDIMM or LRDIMM, but they cannot be combined.
