View Full Version : MSI Introduces Turbo Button To GeForce 8600GT

MSI unveiled its latest graphics card, NX8600GT Twin Turbo, which adds a little twist to what would have been just another GeForce 8600GT Graphics card.

The new addition is a simple button which would switch the graphics card to "Turbo Mode" immediately when pressed.

Comparing to last generation of NVIDIA GeForce GPU, the GeForce 8 family use unified shader processing unit, aka Stream Processors, to simultaneously handle 3D modeling/pixel rendering in a more flexible way. These Stream Processors execute instructions and mapping textures at about 2.x times of default GPU core clock. If the ratio of Stream Processor clock (aka Shader Clock) over GPU core clock is raised, the performance of graphics card can be boosted right the way without generating too much heat.

In order to enjoy benefits of this unique tweaking skill, vBIOS on the graphic card must be re-flashed on the PC platform today. Users will violate the warranty agreement and could highly possible damage their graphic card product if they were not familiar how to re-flash vBIOS.

For the hard-core gamer, MSI launched the NX8600GT Twin Turbo which has two separate vBIOS on-board carrying two dedicated GPU/Shader/Memory clock settings. Users only have to press a hardware button on the bracket, and then the new (higher) clock setting can be applied without re-flashing the vBIOS chip. Also, these two vBIOS chips give extreme enthusiast a Die-Hard workability (another vBIOS chip as spare) if they want to tweak the vBIOS to find out the ultimate performance parameters between Shader clock and GPU core clock.

With the stock speed profile, the NX8600GT Twin Turbo operates at 540 MHz core, 1400 MHz memory and 1450 MHz shader clock. Pressing the turbo button raises the clock speeds up to 580 MHz core, 1600 MHz memoryand 1508 MHz shader clock. MSI claims that switching to turbo mode yields a 20 percent performance boost in 3DMark06.

I'm just envisioning a whole slew of RMA's requests coming from people not happy with their OC's, and/or killing thier cards with rediculous settings.

And how much more would it cost? You might as well just get a better base card.

I haven't seen a turbo button since the days of the 486.

I never even knew there were such things.

Well I have a turbo button on my usb pc controller. At least they are semi decent overclocks tough. I doubt though they will be worth the price premium over a regular 8600GT.

Well, actually whats the point of having a turbo button to boost your GPU's power when you can just overclock the card and let it run at your desired speed the whole time? :S

If it also ups the voltage a bit, could make things more interesting. :)

I could see using if for low power modes. If you were building a HTPC you could lower the default clocks in the bios and make the card run cooler and silent. Then if you wanted to play a game on it, hit a button and it will run a lot faster.

i remember this old pc from my school which had the turbo button... with turbo it would be 66mhz... without it would be a whopping 9mhz :super:

If NVIDIA fully supported this it might actually be a cool idea, IF they
put it on higher end cards.

I never even knew there were such things.

Back in the day I had a 486 DX2-66 mHz computer. It was so fast that a lot of older DOS programs wouldn't run properly, especially older games, as they would run too fast to be usable. In order to play those older games, I had to unpress the turbo button which slowed the processor down and allowed me to use older software.

It also had an ATI VGA Wonder Videocard with a whopping 1MB of Video RAM and could do 1024x768@256 Colors. The card was a VLB card, which is basically a jerry-rigged ISA Bus with an additional connector slot at the end. In terms of length, it dwarfs even today's 8800 Ultras.

a bios switch would be very handy ,well done msi

What a gimmick, just about everyone would always have it pressed!
