If there’s one thing we don’t know about the new MacBook Pro besides what it looks like on the inside, it’s its performance over the previous generation. Well, both of those questions have been answered, and while the CPU shows little improvement in speed, both the flash storage and the Intel Iris integrated GPU perform up to twice as fast.
The new MacBook Pro with Retina display has not only undergone a major upgrade to become a much more affordable computer, but now also enjoys the benefits of Intel’s new Haswell family, such as low power consumption and a revamped Intel Iris integrated GPU .
Well, at MacWorld they’ve decided to put it to the test and compare it to the Intel HD 4000 of the older 13-inch Retina MacBook Pro, and it comes out quite well. The tests used have been Cinebench and Unigine Valley Benchmark, where this new computer shows a performance around 50% higher .
In some cases it not only triples the performance, but it also triples it, compared to the GPU mounted on the old Ivy Bridge. The differences at the CPU level however, are not as great, and are 10% more powerful . Even on the basic 13-inch model, MathematicaMark 8 showed only a 1% improvement over the same model with an Ivy Bridge processor.
In terms of PCIe port performance of the new SSDs, the 256GB model was 33% faster than the same capacity disk in the previous generation, in a test of a 6GB file copy. Surely in moving small files the difference will be almost zero, and you only notice it when high transfer rates are needed .
As a second test, they tested the Blackmagic Disk Speed Test on the three 13-inch models and found that the 512 GB model was more than twice as fast as the basic 128 GB model , with a speed of 710 MBps and 316 MBps, respectively. This is a matter of logic. Let’s think that an SSD is an internal RAID, therefore the more memory chips the disk has, the more work can be divided and the higher speeds can be reached; and now that SATA no longer makes a bottleneck, we can see speeds like that.
However, the reading speeds in the current models were almost the same: 700 MBps vs. 734 MBps . However, the old models (early 2013) were around 400 MBps, considerably less than the new Retina.
