The fact that both are equipped with a different processor makes it difficult to gauge exactly how processor-intensive Killer's network detection algorithms really are, yet even with a weaker Core i5 chip the increase in utilisation appears to be minimal. It's also worth noting that CPU utilisation on the Killer-based laptop was typically 1-2 per cent higher during real-world transfers. Performance between the two is comparable when transferring a couple of large video files. Copying 7GB of photos from each laptop to a NAS results in similar performance. Killer's throughput advantage in the synthetic tests doesn't necessarily translate to superior real-world performance. Killer's Wireless-AC 1535 continues to come out on top and though a wired connection will remain the preferred choice for performance users, 632Mbit/s via wireless has the makings of a useful backup. Switching to the UDP protocol sees wireless throughput increase on each band and on both cards. Performance on the 5GHz band is particularly impressive. We have the latest Wireless-AC adaptors from Intel and Killer on show, and it's the latter that has the edge in terms of TCP throughput. In an effort to keep our results as real-world as possible, we've tested in a home environment where there are half-a-dozen neighbouring WiFi networks competing for airwaves. Evaluating WiFi performance can be a challenge due to environmental factors.
