First, that 7th-gen Core i7 in the HP Spectre x360 13 is indeed faster in lighter loads, outpacing the Surface Book i7 and the Core i5-equipped MacBook Pro 13 with Touch Bar. Moving on to the single-threaded performance in GeekBench 4.01, there are a few patterns we can discern. GeekBench 4.01 single-threaded performance The PC laptops win a moral victory in GeekBench 4.01, but they virtually tie with the MacBook Pros. For MacBook Pro 13 fans that might be something to crow about, because we’re talking about a Core i5 MacBook Pro 13 vs. The Surface Book i7 and MacBook Pro are pretty much dead-even. On the dual-cores, the redesigned HP Spectre x360 13 again shows the newest 7th-gen Core i7’s clock speed advantage over the Skylake models. It’s just more proof that if your tasks really need a quad-core chip, pay for it. Like Cinebench R15, you can see the quad-core XPS 15 and MacBook Pro 15 step away from the dual-core laptops. The first result we’ll look at is the multi-threaded performance. Within the same micro-architecture, however, I think it’s pretty kosher, especially when running the newest 4.01 version of the popular test. I also have a score to report for the MacBook Pro 13 with Touch Bar, as I cribbed the performance of the version with Core i5-6267U and Iris 550 from Macworld’s review. Experts may disdain its cross-platform results between ARM and x86. GeekBench 4.01 multi-threaded performanceĪnother popular cross-platform benchmark is Primate Lab’s GeekBench. The MacBook Pro 15’s Radeon Pro 450 is competent, but the Surface Book i7 and XPS prevail. Maxon’s Cinebench R15 can also measure OpenGL performance. Some MacBook Pro reviews have said the graphics don’t measure up in games, while in “work”-related tasks, they rules. The MacBook Pro 15, with its Radeon Pro 450, finishes in a firm third place. Unexpectedly, the GeForce GTX 960M in the XPS 15 finishes just ahead of the GTX 965M in the Surface Book i7. The last band is the graphics performance of the discrete-GPU laptops. The results make me wonder whether this isn’t some driver optimization that Intel put into Kaby Lake but not Skylake. I really expected the Iris 540 laptops to come out in front. The pair of 7th-gen Kaby Lake laptops from Dell and HP are a good 25 percent faster than the 6th-gen Skylake laptops in OpenGL. Both are nearly dead-even, which validates this test for comparing OSX to Windows 10 performance. Both use Intel’s Skylake CPU and include “faster” Iris 540 graphics with 64MB of embedded DRAM inside the CPU. At the bottom is the new MacBook Pro 13 and an older Dell XPS 13 model. The results here break down into three bands. Our last Cinebench R15 test measures performance with OpenGL, a popular graphics API used for rendering professional CAD/CAM applications and a few games. Overall, there’s little difference in single-threaded loads. We switched Cinebench R15 into a mode where it measures single-threaded CPU performance. That Kaby Lake CPU is indeed pulling its weight. I would’ve expected the quad-core MacBook Pro 15 or Dell XPS 15 to lead the pack, but nope. The real shocker is how the HP Spectre x360 with a 7th-gen CPU comes out the clear winner. When running a test in single-threaded mode, the Core i7’s advantage with short burst loads shows up big-time. Once you heat them up, the clock speeds crank back. That’s because Core i7 chips in laptops excel at short, “bursty” loads. Its 7th-generation Core i5 CPU could hang with the Core i7 chips on heavier loads, but on lighter loads, it ends up being last. The surprise to many will be the result from the Dell XPS 13. It’s a valuable way to gauge how fast a laptop will be in applications or tasks that don’t use all the cores available. Cinebench R15 single-threaded performanceĬinebench R15 has an optional test that lets you measure the single-threaded performance. Its 6th-gen CPU is hanging right with the 7th-generation Kaby Lake CPUs in the new HP Spectre x360 13 and the new Dell XPS 13.Ĭinebench R15’s multi-threaded benchmark shows you the clear difference between quad-core and dual-core CPUs. The surprise is where the Surface Book i7 finishes. It’s basically the same as the last-gen XPS 13 with a similar Core i7-6560U. Among the dual-cores, the Core i5-based MacBook Pro 13 is last, but not by much.
