When Apple introduced its newest M2 Professional- and M2 Max-based MacBook Professionals final week, the corporate boasted about efficiency positive factors (as much as a 20 p.c uplift for the CPU, as much as 30 p.c for the GPU) and improved battery life. Sadly, it seems that one space of efficiency has taken a step backward for M2 Professional-based MacBook Professionals, no less than for the $1,999 base mannequin with a 512GB SSD.
A number of stories affirm that the SSD on the 2023 14-inch MacBook Professional (M2 Professional, 512GB) is considerably slower than the one discovered within the 2021 14-inch MacBook Professional (M1 Professional, 512GB). The primary phrase concerning the efficiency downgrade got here from @ZONEofTECH, who in contrast the 2 programs. The M2 Professional system scored 2929 MBps write and 2703 MBps learn utilizing the AJA System Check Lite benchmark. Its M1 Professional-based predecessor scored 3450 Mbps on the write check and 4081 MBps on the learn check.
BREAKING: We’ve simply found that the bottom 14” M2 Professional MacBook Professional (512GB) is significantly slower than the earlier 14” M1 Professional mannequin. Apple is probably going utilizing single SSD modules once more (like the bottom 256GB M2 Air and M2 MacBook Professional). Extra testing to come back. pic.twitter.com/3kMiHVDxaFJanuary 24, 2023
In his tweet, @ZONEofTECH opined, “Apple is probably going utilizing single SSD modules once more (like the bottom 256GB M2 Air and M2 MacBook Professional).”
Additional affirmation got here this afternoon from Mac-centric web site 9to5Mac, which additionally seen slower efficiency with the brand new base mannequin MacBook Professional. The publication used the Blackmagic Disk Velocity Check on the 2023 MacBook Professional (M2 Professional, 512GB) and recorded writes of 3154.4 MBps and reads of 2973.4 MBps. For comparability, the 2021 MacBook Professional (M1 Professional, 512GB) readily available put up larger numbers at 3950.8 MBps and 4900.3 MBps, respectively.
Given the efficiency degradation, 9to5Mac determined to open the case on the brand new MacBook Professional to see if the chip configuration had modified in comparison with the earlier era. “Certain sufficient, the place the 512GB M1 Professional MacBook Professional had two NAND chips seen on the entrance of the motherboard and one other two on the again, the M2 Professional MacBook Professional had just one seen on the entrance of the board,” the publication wrote. “There may be probably a second NAND chip instantly opposing this, because the M1 had.”
In response to iFixit, the 2021 MacBook Professional’s 512GB SSD is break up amongst 4 128GB NAND chips. Its 2023 MacBook Professional counterpart as an alternative makes use of two 256GB NAND chips in parallel. That might account for the efficiency lower for the brand new MacBook Professional.
Apparently, this efficiency downgrade extends to the 256GB variant of the 2023 Mac mini with the M2 SoC. When Apple introduced the M2- and M2 Professional-based Mac minis final week, the corporate additionally diminished costs for the bottom mannequin. The M1 Mac mini had a beginning value of $699, whereas the brand new M2 Mac mini dropped that value to only $599.

Now, we all know how Apple was capable of obtain no less than some of these price financial savings: it skimped out on storage efficiency. The 2020 Mac mini (M1, 256GB) makes use of two 128GB NAND chips in parallel and achieves 2733 MBps write and 2854 MBps learn with the Blackmagic Disk Velocity Check, in keeping with Twitter consumer @t4bl3r0n3. Conversely, the 2023 Mac mini (M2, 256GB) sees its outcomes roughly halve to 1431 MBps and 1482 MBps, respectively. Brandon Geekabit additionally confirmed these storage efficiency drops in a YouTube video.
If all of this sounds acquainted, Apple carried out the identical SSD switcheroo with the bottom model of the MacBook Air (M2, 256GB). Utilizing slower SSDs on the 2023 MacBook Professional and 2023 Mac mini may affect file switch efficiency and general system efficiency. As well as, any functions that exhaust the obtainable bodily reminiscence would want to fall again to the SSD for digital reminiscence. The Mac mini would probably be impacted extra by paging out to the SSD, provided that the bottom 256GB storage configuration solely comes with 8GB of RAM.
Apple’s determination to decrease storage efficiency in alternate for a $100 value reduce on the entry-level Mac mini is considerably comprehensible. Nonetheless, the step backward in storage efficiency on the $1,999 MacBook Professional is much less defensible. For purchasers paying high greenback for a “professional stage” machine, you would not anticipate storage efficiency to take such a dramatic hit.
