Sony VAIO Pro 13: Exceptionally Portable

Sony VAIO Pro 13: Performance

In most areas, the performance of the VAIO Pro 13 is more than sufficient. Loading up Windows and common applications, surfing the web, and even video encoding (especially with an application that supports Quick Sync) are all plenty fast. There are faster laptops out there, certainly, but they don't have anywhere near this level of portability. Here's our standard selection of performance metrics, and you can see that the VAIO Pro 13 is basically in line with other Ultrabooks. Note that most of the other Ultrabooks have used Core i7 ULV processors, so here the VAIO Pro 13 is at a disadvantage. The cores specs for the tested laptops are listed in the table below, and additional benchmark results are available in Mobile Bench.
 

In our general performance graphs, here we get another results showing that Haswell isn't really any faster than Ivy Bridge in most tests (unless it has a GT3/GT3e iGPU, or in specific tests that leverage the new instructions). Move to the 3DMark results and the VAIO Pro 13 doesn't really look so hot. It's now clearly slower than the Core i7 Ivy Bridge Ultrabooks, which isn't something I'd expect from 20 EUs. Either Intel actually has slower EUs in Haswell than in Ivy Bridge, or Sony is curbing performance of the iGPU to keep within their desired thermal range. Our gaming results continue this trend:

Other than in StarCraft II: Heart of the Swarm and Tomb Raider, the VAIO Pro 13 ends up being slower than every other Intel Ultrabook that we've tested. The Acer V7 isn't technically an Ultrabook, though it's close enough in many respects, but we can see just how much even a moderate dGPU adds in terms of performance. We also have some results for Crystalwell (i7-4750HQ) in Mobile Bench that we're not including here, and GT3e is much faster as well (though the Clevo W740SU doesn't do all that well in the battery life department). Perhaps GT3 would help the VAIO Pro 13, but several games seemed to have issues maintaining higher iGPU clocks – Metro for instance showed cyclic higher/lower performance during the benchmark runs. It's mostly a moot point, though, as outside of light gaming the HD 4400 simply isn't fast enough to handle a lot of games.
