Upgrade rMB 2015 -> 2017: expected speed increases and 4k?

[sufs]

Hi,

I have a 2015 rMB that has been totally awesome. Just got myself a 4k usb-c monitor, and it runs perfectly on 30hz no issues. With High Sierra the animations are super smooth as well (even when running both screens).

I do some web-development, and this has been my main work horse for several years, but I'm starting to feel that things like Webpack etc. takes just a tad more time than I appreciate when developing.

How much faster would an entry 2017 rMB be than a entry level 2015?

I love that its fanless and portable, but the base MBP 13" is also compelling. In either cases, I would get 4k @ 60hz, right?

You can get 4Kp60 with your 2015 if you have the right dongle.

The MacBook (2015 and later), MacBook Pro (2016 and later), and iMac (2017 and later) support these resolutions and refresh rates over HDMI 1.4b when using the USB-C Digital AV Multiport Adapter with macOS Sierra 10.12 or later:

• Up to 1080p at 60Hz
• 3840 x 2160 at 30Hz

These computers also support 60Hz refresh rate over HDMI when used with a supported HDMI 2.0 display, HDMI Premium Certified cable, and a compatible third-party USB-C to HDMI 2.0 adapter.

The 2017 base has made huge performance gains over the base 2015 - that said, if you plan to use 4k/60hz frequently, I would personally lean towards the 13-inch MacBook Pro (especially if you want to use USB 3 devices while using the display.)

It not huge different compare as 15 and 17.

About 20% performance up compare as 2015-2017 base model to i5 512GB.
If you require fast machine, get MBP13 or up.

Actually, it's about 25% to 40% depending upon the benchmark comparing 2017 m3-7Y32 vs 2015 m-5Y31.

Cinebench R15 2017: 264 (+25%)
Cinebench R15 2015: 211

Geekbench 4 2017: 7000 (+43%)
Geekbench 4 2015: 4900

But yeah, if you want more performance, get a MacBook Pro. Not only does it have more performance, it also has more sustained performance. OTOH, the good news is that the 2017 MacBook also has a 16 GB option now.

Those benchmark have restricted may not refer of real case especially for programming.
Cinebench is Rendering test cannot be fully use of CPU (many scene for programming such as reindexing on IDE can draw more power that Cinebench ), and Geekbench 4 is short burst test.

If you're talking software development then the 2017 may (or may not) have a huge advantage since it has a 16 GB option.
