And when the client was in my home office, 65 feet away and separated by three insulated interior walls, the Killer NIC was more than 25 mbps faster. When the client was in the same room as the router, 9 feet away with no walls in between, it was 10.7 mbps faster than Intel’s component. The two adapters traded places on the 2.4GHz frequency band, but when the Killer Wireless-N 1202 won, it won by a significant margin. I also used the Asus RT-N66U to compare the adapters’ TCP-throughput performance, using JPERF (the Java front end to the TCP-throughput benchmark iPERF). The Killer NIC delivered similar performance when I switched the clients over to the router’s 5GHz network-slightly less than 2 milliseconds-but Intel’s card registered a much higher average ping of nearly 8 milliseconds. What’s more, GaNE measured one-and-a-half times more jitter with Intel’s card than it did with Qualcomm’s.

GaNE reported an average ping time for the Killer Wireless-N 1202 of about 1.5 milliseconds, and an average ping of nearly 4 milliseconds for the Intel card. I then performed six runs of the GaNE benchmark. I set up the two wireless clients about 9 feet from the router in the same room, so no walls stood in between, and I connected them to the router’s 2.4GHz network. The GaNE benchmark, which measures latency and jitter, shows the Killer NIC to be the superior Wi-Fi adapter for latency-sensitive applications such as online games. I used my longtime favorite 802.11n Wi-Fi router, a dual-band Asus RT-N66U, for these tests. The tool measures latency between two networked PCs by sending a 100-byte packet on a round trip over the network every 50 milliseconds (100 bytes is the typical packet size on gaming networks, and 50ms is the typical interval between packets on the same). This way, both client adapters are subject to the same environmental conditions-an important variable when you’re benchmarking wireless performance. GaNE measures real-time performance from two wireless clients at once, recording the results on a third computer that’s hardwired to the network.

Qualcomm offered to allow us to examine the program’s source code to ensure that there were no shenanigans. To evaluate each card’s ability to combat network latency, Qualcomm provided me with its Gaming Network Efficiency (GaNE) benchmark to measure ping (the time required for a packet to make a round trip on the network) and jitter (undesirable deviations in signal timing). The Killer Wireless-N 1202 is certainly inexpensive enough: I’ve seen it selling online for as little as $35 (Intel’s card is street-priced at about $30).

You can also purchase one of these cards by itself and upgrade your existing notebook, provided that the system has an available Mini PCIe slot to host the card (a common feature on better notebooks). Some gaming-laptop manufacturers, including Alienware, offer Killer NICs as standard equipment, while others offer the adapters as added-cost upgrades. Both also support two spatial streams for a maximum physical link rate of 300 megabits per second. Robert Cardin We benchmarked two otherwise identical Alienware laptops: one outfitted with a Killer Wireless-N 1202 NIC (left) and the other with Intel’s Centrino Advanced-N 6230 (right).īoth NICs are dual-band adapters that can connect to an 802.11n router on either the 2.4GHz or 5GHz frequency band.

To demonstrate its prowess in this area, the company sent me two identical Alienware notebooks, one equipped with Qualcomm’s Killer Wireless-N 1202 and the other with Intel’s Centrino Advanced-N 6230. Gamers are always hunting for a competitive edge, and the folks at Bigfoot Networks-now a part of Qualcomm Atheros-have long promised to deliver network interface cards that perform better with online games and other latency-sensitive applications.
