Hardware and Models

The Killer NIC comes in 2 models; the K1 and the M1. Both models contain a Freescale PowerQUICC processor, 64 MB RAM, a single Gigabit Ethernet

The primary difference between the models is that the M1 has a stylized metallic heat sink

, and a processor running at 400 MHz, while the K1 lacks a heat sink, and runs at only 333 MHz. Currently performance differences between the cards are limited, although it is believed that future programs designed for the cards will be capable of utilizing the increased processing power of the M1.

Flexible Network Architecture

The Flexible Network Architecture is a framework used to create and run Flexible Network Applications. These applications run on the embedded Linux operating system, and are accessed through a driver interface within the host computer's OS. Aside from that, they use a very little of the computers resources, instead handling processing on the cards CPU. Bigfoot Networks has released a Software Development Kit

Reception

Early reactions to the Killer NIC centered on price, with its initial MSRP of $280. This led to widespread skepticism and speculation that the product was merely attempting a money grab, hoping to cash in on the "bling" aspect of enthusiast computing. However, using a F.E.A.R. benchmark IGN

 found that the Killer NIC increased framerate from 15.41 to 23.5 frame/s. While recognizing the potential for real performance gains, they also noted that the test systems were already struggling with the game, and that having a higher-end machine in the first place could offset the gains made by the Killer NIC. This supposition was supported by Anandtech

's findings, which showed some real, but much less dramatic gains. IGN declined to rate the card with a score, saying that more testing with other games would be needed. They remarked that the potential performance gain with the Killer NIC was probably higher than upgrading a $300 video card from one generation to the next. Anandtech noted that the people who would stand to gain the most benefit from the Killer NIC, the low-end users, would also be the ones least likely to pay $280 for a network card.
