Hi all - Looking for some guidance here.

Noticed that the Memory Score for my 2018 MacBook Pro (TouchBar, i5 quad core, 16GB RAM, 256GB SSD) is consistently lower than the 2017 MacBook Pro (no TouchBar, i5 dual core, 16GB RAM, 256GB SSD) for Single Core and Multi Core CPU Benchmarks.

I'm a bit surprised by this because I was expecting the 2018 MBP to be better in this aspect as well.

Is this something to be concerned about? Trying to understand what expectations should be had here.

Here are the details of the memory scores - Thanks in advance for any help here!

2018 MBP Single Core
- Memory Score: 3771
- Memory Copy: 4076 (11.3 GB/sec)
- Memory Latency: 3260 (132.8 ns)
- Memory Bandwidth: 4038 (21.6 GB/sec)

2017 MBP Single Core
- Memory Score: 3965
- Memory Copy: 4153 (11.5 GB/sec)
- Memory Latency: 4094 (105.7 ns)
- Memory Bandwidth: 3669 (19.6 GB/sec)

2018 MBP Multi Core
- Memory Score: 4351
- Memory Copy: 5278 (14.6 GB/sec)
- Memory Latency: 3616 (119.7 ns)
- Memory Bandwidth: 4318 (23.1 GB/sec)

2017 MBP Single Core
- Memory Score: 4464
- Memory Copy: 5460 (15.1 GB/sec)
- Memory Latency: 3976 (108.9 ns)
- Memory Bandwidth: 4098 (21.9 GB/sec)

    Oops! The last heading should read 2017 MBP Multi-Core, not Single Core

    Just an update here. I tested the 2018 i7 MBP (quad core, 16GB RAM, 256GB RAM) and noticed similar results. Sticking with my 2018 i5 for now.

    If anyone is curious, here are the tests:

    MacBook Pro (i5 13-inch Mid 2017)

    MacBook Pro (i5 13-inch Mid 2018)

    MacBook Pro (i7 13-inch Mid 2018)
