When I bought my 32GB of RAM for my Mac Mini, I spent $288 on 32GB of 2666MHz DDR RAM. But at the low end? If Apple is shipping ECC RAM with the entry level unit, it probably won't buy you much in terms of either stability or performance. Some Xeon motherboards can work with either ECC or non-ECC sticks, but we don't know that about the new Mac Pro.ĮCC becomes quite valuable for stability, especially at very high speeds and with terabytes of RAM in use.
My bet is that it's the 2666MHz stuff.Īpple states that the Mac Pro supports up to 1.5TB of ECC RAM, but it doesn't specifically call out whether the base 32GB RAM array is ECC RAM. That said, Apple does not specify whether the base model is shipping with 2933MHz RAM or the slower (and cheaper) 2666MHz RAM. The memory will simply drop back down to four-channel mode and run as if the machine was designed as a four-channel box. While the system won't derive the performance benefit of six channels of data moving at once, there's no real performance penalty either. Therefore, in six-channel memory, you would get the best performance with six matching sticks.īut the base Mac Pro ships with four sticks. In quad-channel memory, you get the best performance by matching sets of four sticks.
Generally speaking, if you have dual-channel RAM, you get the best performance by matching pairs of sticks. This might seem odd, because there are four DIMMs on a six-channel architecture. The Intel W-3223 processor in the base Mac Pro can only address 2666MHz memory, even though the machine itself is built for 2933MHz RAM. Base memoryĪccording to Apple, the base Mac Pro ships with four 8GB sticks of DDR4 ECC memory. If you're going to be stuck with one CPU for the life of this very expensive box, you'd probably be better off with a Core i9-9900K rather than the relatively weak Xeon W-3223. It's unfortunate, therefore, that Apple didn't say whether the base model CPU can be upgraded later. If it was, the Core i9 would have been a higher-performing model for most tasks at that performance level. Undoubtedly, the Mac Pro motherboard wasn't designed to optimize for the lower-end Xeon chip in the entry-level machine. The i9 is also $500, instead of the Mac Pro's base W-3223, which lists for $750. According to their GeekBench scores, the i9 beats the Xeon W-2123 and Xeon W-2145 in both single and multi-threaded performance. In terms of the more consumer-level Core i9 chipset, the most comparable model is the i9-9900K, which also runs at 3.6MHz and has eight cores and 16 maximum threads.
The closest performing shipping model with eight cores and 16 threads is the 3.7GHz W-2145. Of the Skylake processors, the 3.6GHz W-2123 is probably the closest in performance, but that has only four cores with up to eight threads. Our best opportunity is to compare similar Skylake Xeon W processors. Apple is including the $450-cheaper W-3223 in the base model Mac Pro.īecause this processor has just been announced, we don't have good benchmark numbers. But I carefully cross-checked all the detailed specs provided by Apple with Intel's processor specs, and those other sites are wrong in their estimations. Note: You may find that some other deconstructions of the Mac Pro's pricing online have guessed that the base Mac Pro will include the more expensive W-3225. It seems to benefit mostly high-end use, but the comparatively weak and slow W-3223 model may actually incur a performance penalty if those extensions are enabled. That said, the exact benefits (and performance cost) that come from use of the AVX-512 extended chipset are somewhat controversial. This extended chipset provides some advantages for scientific and machine learning applications. This is a pretty low-end processor, but it does support Intel's AVX-512 instruction set.
That's the W-3223 model, which is priced at $749. Intel conveniently announced Cascade Lake the day after the WWDC announcement of the new Mac Pro.Ĭascade Lake does have a 3.6GHz chip, with a Turbo Boost up to 4.0GHz (although max Turbo Boost is listed as 4.2GHz). There are no 3.5GHz Xeon W chips in the Skylake line. So, which processor is this? According to Wikichip, it's not a Skylake Xeon W. Apple states that the processor on the base machine is a 3.5GHz Intel Xeon W processor with eight cores, 16 threads, Turbo Boost up to 4.0GHz, and a 24.5MB cache. I spent a lot of time digging through the specs for the processor. What businesses need to know (TechRepublic).iPadOS: Improved Safari, multitasking, new homescreen.
