I can benchmark 2015 m3 vs 2017 i7
- Thread starter Ynk
- Start date
- Sort by reaction score
My CPU load test of choice is the distributed.net RC5 project (https://www.distributed.net/Download_clients)
My 2015 m3 achieves 14.3M keys/second steady state with 2.0GHz and 82 degree CPU temperature
My 2017 i7 achieves 24.4M keys/second steady state with a 2.5 - 2.6 GHz throttle and 94-97 degree CPU temperature
The palm rests are not warm at all on either machine, the 2015 is only slightly warm on the bottom - the 2017 is definitely a lot warmer but I wouldn't describe it as hot just warm.

When I bought the 2015 I knew it was going to be a big compromise, the CPU is quite limited and the GPU performance generally poor even just for basic tasks/web browsing. Moving to the 2017 I'm really happy, it finally has enough grunt for my daily needs and the general responsiveness (especially with 20+ Safari tabs open) is so much better. Will be keeping the 2017 for sure and selling off my 2015

What are your thoughts on the 2nd generation keyboard?

How would one go about selling a 2015 that still has AppleCare?
You're running the OGR workload not RC5. Add the following lines(or replace) in your .ini config file (same directory as the application):
[misc]
project-priority=OGR-NG=0,RC5-72
[triggers]
pause-on-no-mains-power=no
[display]
progress-indicator=rate
Could you please try to run the Intel Linpack benchmark on both machines? You can download the benchmarks from https://software.intel.com/en-us/articles/intel-mkl-benchmarks-suite
(you need to double click to unpack m_mklb_p_2017.3.019.tgz, and then open Terminal - or again double click - to run the benchmark "runme64" in /m_mklb_p_2017.3.019/benchmarks_2017/mac/mkl/benchmarks/linpack )
I've been running the Feb 2017 benchmark on MBA mid 2013 with a 1.3GHz i5 and MBA Early 2015 with a 2.2Ghz i7, and got the following numbers for the 10,000 size:

When you say 2015 "M3" which Core-M are you referring to? Core-M 1.1, 1.2 or 1.3? I'm assuming the 1.1?
Unless I'm mistaken, there was no M3 option back then - that branding came with the 2016 model - so I'm just wondering as I'm interested in the 2017 i7, currently using a 2015 Core-M 1.1.
