Before we get into game testing we wanted to analyse the performance of the onboard Killer NIC.
Firstly, we need to discuss Latency V Throughput. Latency is commonly refered to as ‘Lag’. This is a measurement of delay for a network packet or series of packets. Latency is a good measure of the real speed of your network or Internet connection – low numbers indicate fast networking.
Throughput is different, because this is a measure of bandwidth, basically how much data can be delivered to its destination. This is often the system by which consumer Internet connections are classified and priced.
It is important to understand that Latency does not measure Throughput. 30Mbps might seem like its a service ‘speed’ but in actuality its explaining what bandwidth is available to a connection. Standard networking devices are designed to maximise throughput. They are not however designed or optimised to lower latency for online games.
When you play a game online you might think its using 8mbit of your bandwidth, but in reality you will often find its hovering around 25-100kbps. Sometimes if you are playing a game and you notice lagging, its not that your connection isn’t handling massive amounts of data its that the packet delays are causing lag and therefore game responsiveness.
The Game Networking DNA Technology that is utilised in the BigFoot Killer Nic product is tuned to reduce latency, therefore optimising the gaming connection you experience when online. Subsequently it would make sense that with this technology you could experience smoother game play while the machine is multitasking in the background.
Installing the card is a straightforward enough process, you insert a CD and install the driver – before driver installation Windows 7 reports the product as a PowerPC based product.
Interestingly, We had a standalone KillerNic 2100 installed before we used this card, but the Visiontek product requires a special driver available on the Visiontek software disc.
Driver installation only takes a few minutes and the firmware on the card is updated. This is a similar procedure to the standalone product.
It is important you don't turn the machine off during this installation or the onboard NIC could get damaged.
The standalone software suite available from the Bigfoot Networks website works fine with the onboard NIC, highlighting all the options available to the end user. This software really is excellent.
The first test we decided to use was the Game Network Efficiency (GANE) Test, which is in place to simulate real world network performance for online PC games. This test is used to create a gaming load on a Windows PC as well as transmission of gaming network traffic over a local network. This test is also designed to test two network cards at once making direct comparisons between both at the same time.
The setup is a little complex, but ill describe it in a step by step manner.
Firstly you connect the host (listen/server) PC to a gigabit switch through the standard onboard gigabit ethernet connection. The Killer 2100 is then installed on the other test PC and it is connected to the gigabit switch via both the Killer Network gaming card and the onboard NIC.
On the server PC we then configure the properties of the onboard network card to have a static IP address. We then adjust the subnet mask to 255.255.255.0. The test PC is then configured in a similar manner, but we assign different static IP’s to both the onboard NIC and the Killer 2100. Again the subnet mask is set to 255.255.255.0.
On the main test PC we then go into advanced via the IPv3 properties window. We then uncheck the ‘Automatic Metric” box and set the metric value to “1″. Both cards need this applied as the NIC uses it to send network traffic. If we leave this setting at ‘automatic’, Windows does not alternate between the NICs and instead will send all the traffic through one card rendering the test useless.
The next stage is to run GANE on both the server/listen PC and the main test rig. GANE measures then compares latency between two network cards installed on any PC. This is handled by a procedure of sending 100 byte packets over the local network on a round trip, every 50ms. Kitguru has selected 100bytes as the packet size because this is a good real world representation of a standard network packet. We want to run this size specifically to test Bigfoot's claims that many network cards are not optimised for this ‘game’ related data packet size.
While we set up the server PC we also need to run a game benchmark on the main PC and in this case we will use Resident Evil 5 in DX10 mode with the built in benchmark at maximum settings on our screen at 1920×1200 resolution. While we are running this, we are sending packets between both NICs on the main PC to the receiving (listening) PC. This mirrors a real life situation of playing a game online while transmitting data back and forward.
Adapter 1 is the Killer Nic and Adapter 2 is the motherboard solution. The results above show that the Killer 2100 is 4.0 faster than the motherboard solution and delivers a result with almost 25 times less jitter. On a lesser solution this can actually be as high as 35 times faster with 120 times less jitter!
Our average UDP ping was 0.000287643 on the Killer 2100 and it was 0.003075006 on the onboard solution. Our average mean ping was 0.232525 on the Killer 2100 and 0.921490 on the onboard solution. The worst case scenario is more critical as it could cause lag online. The onboard solution is 5.287735 while it is 0.355063 on the Killer 2100 … massive differences. Bear in mind this is obviously over a very tight local network, but when heading online to game on a server thousands of miles away this will increase, exponentially.
Thats a pretty good product, especially if you need a new gfx and your onboard lan is crap (like mine). I have a HD5770 already and I like it, I only game at weekends and ive found its fine, even with the newer engines on my tv.
Nice product, I like the cooler design, its rather funky looking. HD5770 is a good card, slightly overshadowed by the 460, although with the recent price drops to under 100 quid, its one of the finest value products on the market.
How would I get this into the UK: wouldnt customs be costly?
Finally a good review of this. no one else reviewed it ! Dont know how you guys do it being a Uk site, but kudos!
I want a replacement for my 5450 and I need a good lan card, been waiting for this for ages. just ordered it of newegg as it was 15 bucks less than Dells page which I had my eye on for a month.
thanks!
Yeah I saw Dell are selling this for $205 in the states. 15 bucks less on newegg, which is great.
Didnt powercolor do something similar? im sure its available in UK ?
HD5770 was a great board, its a bit long in the tooth now, although after seeing this one, I can see visiontek are offering something a little different, which is very cool. Like it.
They need to offer the Killer nic on something like a 6950 or 6870,.
I bought one of these for WOW and its transformed my clan games. love it.
Any ideas if they plan to bring this out in any other of their range? I like the idea, but the 5770 wont do what I need.
Great idea, id love to try the Killer NIC myself, but id be downgrading my card. and I dont fancy another slot gone for the dedicated card.
6970 and 6950 please chaps 🙂 Wonder why sapphier or XFX dont do it.
hello kitguru,
question, when if your GTX560 review going to come up? Also could you compare it to the EvGA FTW 460 or OC a GTX460 to those levels.
