NVIDIA GeForce GTX 285 in Tri-SLI Tested

Unlike the GTX 295, we can install three of the GTX 285 cards into a compatible system and what you essentially end up with is three cores. And while this is less cores than a Quad-SLI GTX 295 setup which only offers two cards but a grand total of four GPUs, the performance on a GTX 285 is superior to a single core on the GTX 295.

With the help of Inno3D, ASUS and GIGABYTE, today we'll be having a look at how a Tri-SLI setup performs and what kind of performance improvements we get as we slot in not only a second card, but a third.

Looking over at Newegg, you can pick up the ASUS ENGTX285 for $399.99 at the moment, with the other two being similarly priced. Obviously times this by three to end up with your Tri-SLI setup.

Since we've looked at two of the three cards already, with the ASUS scheduled for a better look sometime next week, we won't go into any detail on the particular brands of cards we're looking at today.

With everything said and done, let's have a look at the test system and a closer look at the GPU-Z information we have on hand to make sure everything is working. Then there's only one thing to do and that's to benchmark the cards through our real world and synthetic games and applications.

Above you can also see that we're using the stock clocks on the cards. Today we'll simply be looking at the performance of adding the extra cards across our Vista benchmarks. With everything said and done, let's get stuck into the benchmarks and see if Tri-SLI is working a bit better than how it's been in the past.

It doesn't come as any real surprise that across the board we see good gains with the GTX 285 SLI setups. Adding a third card into the mix gives us a good boost in performance under the intensive Extreme preset.

Under PT Boats we can see adding a second card into the mix yields a performance increase at 2560 x 1600. While Tri-SLI gives us no extra performance, it's good to see it doesn't go backwards.

World in Conflict is a real-time strategy video game by Massive Entertainment and to be published by Sierra Entertainment for Windows (DX9 and DX10) and the Xbox 360.

The game is set in 1989 where economic troubles cripple the Soviet Union and threaten to dissolve it. However, the title pursues a "what if" scenario where, in this case, the Soviet Union does not collapse and instead pursues a course of war to remain in power. It is an intensive new game is sure to put plenty of stress on even the latest graphics cards and we use the built-in benchmarking for our testing.

Left 4 Dead uses the latest version of Valve's Source engine, with improvements such as multi-core processor support and physics-based animation to more realistically portray hair and clothing, and to improve physics interaction with enemies when shot or shoved in different body parts. Animation was also improved to allow characters to lean realistically when moving in curved paths.

Rendering and artificial intelligence were scaled up to allow for greater number of enemies who can navigate the world in better ways, such as climbing, jumping or breaking obstacles. Lighting has been enhanced with new self-shadowing normal mapping and advanced shadow rendering that is important to convey information about the environment and player actions.

Under the most intensive settings in Left 4 Dead we can see that adding a second card yields a good performance increase, while a third offers only a small one.

Power Consumption Tests

Using our new PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly known as to our readers, we are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into AC wall socket).

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD ROM or many cooling fans.

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

NVIDIA GeForce GTX 285 in Tri-SLI Tested

It doesn't come as any surprise that the more graphics cards we add, the more power is needed. A Tri-SLI setup us tipping almost 700 Watt at load, while a SLI one is just over 500 Watt. The idle wattage also jumps up as we add another card into the mix.

Final Thoughts

NVIDIAs SLI technology has come a long way; with modern day games it isn't plagued with the same issues that we saw only months ago. Does this mean that Tri-SLI is the best option? - No, not really. But SLI is a great option and manages to offer some serious power.

Two things have made SLI good today, though; one is that the drivers have become better and better with every release. NVIDIA deserve a good pat on the back for that. The other is thanks to Intel who has implemented SLI into the X58 chipset. It was good to see that NVIDIA learnt to swallow its pride and realize that the best thing for them and their technology was to let Intel implement SLI into their chipsets.

But while there's some serious performance on offer here, there still continues to be a huge list of cons to a setup like this. Price is one of the biggest and the other thing is that unless your CPU is clocked high, be it by overclocking or buying a top of the line i7, you're just not going to get the performance that you should be getting out of the setup.

Then there is of course the heat that comes out the back of your case which is simply huge and in a small area you're really going to be feeling it. We also have some serious power getting sucked up, meaning a decent power supply is a must.

Sure, the list of cons are big, but if you look at the pros such as performance, more performance and then a little bit more performance again, it's not hard to accept a Tri-SLI setup with open arms; because as mentioned, it offers great performance.

As a quick reminder, the ASUS EN285GTX sells for $399.99 at Newegg.

This is a good, stable and very fast setup that's going to cost a small fortune. The thing is, though, if you have the money, want the power and just love gaming, you're not going to be disappointed!
