That is, of course, what we do here, as we stick solely to testing XPS 13 and XPS 15 laptops. We won’t rehash all of that, but we will say the test is far more relevant when it’s kept on the same CPU microarchitecture. While Geekbench has been controversial at times, it’s mostly only when enthusiasts try to point to it as proof that a tablet chip is as fast or faster than a desktop chip. While both POV Ray and Cinebench hone in on CPU performance while rendering or ray tracing, Geekbench 4 tends to be a little more general and relies on a large list of algorithms that its maker, Primate Labs, considers relevant to processor performance. The 8th-gen Core CPU did well in single-threaded POV-Ray as well. This is, again, a very good showing for the new 8th-gen Core i7-8550U chip. Because both CPUs have the same boost clock of 3.5GHz, we’re not surprised. Note how the 6th-gen quad-core Core i7-6700K actually falls in line just behind the dual-core Core i7-7500U. The result places the new 8th-gen Core i7-8550U in a good place, just behind the Core i7-7700HQ in the XPS 15. Like Cinebench, the POV benchmark can use a single compute thread. The 8th-gen quad-core Core CPU sticks close to 7th-gen quad-cores in POV-Ray multithreaded tests. We again see the 8th-gen quad-core Core i7-8550U easily blowing away the older 7th-gen dual-core and hanging with the much hotter 45-watt quad-cores.
It’s been updated and moved to x86, of course, and it’s still a valid performance benchmark. Next we ran POV-Ray, a ray-tracing application that literally dates back to the days of the Commodore Amiga. The higher 4GHz boost clock of the new 8th gen Core i7 gives it a leg up over the 7th-gen CPUs. Given that the vast majority of applications people use rely far more on single-threaded performance than multi-threaded performance, this result is more important than it might seem. Cinebench R15 clearly shows that boost speed can pay off. Okay, what’s really going on here? Well, if you look at the detailed specs in the Intel ARK chart (or click this to see them) you can see that the new Core i7-8550U has a higher turbo boost speed of 4GHz, compared to the 3.8GHz boost speed of the Core i7-7700HQ. You’d think it would be the Core i7-7700HQ in the newest XPS 15, but no, it’s the new Core i7-8550U in the XPS 13. IDGĭayum: Look at that 8th-gen quad-core CPU hanging so close to its beefier 7th-gen predecessor.Ĭinebench R15 also allows us to test performance of the application in single-threaded tasks, so we threw the switch and ran all five laptops through the same task. What does this mean? It simply means, dayum: Intel’s new 8th gen is fast. Anyone who thought Intel couldn’t pull off a quad-core in a 2.5-pound laptop has to eat their wordss as the Core i7-8550U simply destroys the 7th-gen Core i7 dual-core CPU, and for the most part hangs surprisingly well with the much hotter 45-watt quad-core chips in the two XPS 15 laptops.
