NVIDIA also tells us that GPU Boost (at least initially) will not be available in mobile GeForce 600 series parts. It can’t be disabled, but users will still be able to overlcock their GPU-they’ll just have to account for the Boost clock, which will always be some percentage above the base clock. We should also point out that GPU Boost doesn’t preclude overclocking. And if you’re playing a game that’s doesn’t result in significant GPU power consumption, the GeForce GTX 680 will likely be running closer to its peak GPU Boost clock than its base clock most of the time. Reference cards have a default GPU Boost clock of 1058MHz.
The majority of the time, however, while gaming, it will be clocked higher than that. With GPU boost, with those games and applications that run at a lower power profile, power / clocks can be boosted automatically and dynamically to increase performance.Īs we’ve mentioned, the GeForce GTX 680 has a 1006MHz base clock. NVIDIA looked at that gap between peak power and unused power in certain applications and called it the “Boost opportunity”. But when you do that, you leave power and performance on the table for applications that don’t consume as much power. Traditionally, GPU clock speeds were set based on the most stressful applications and conditions. GPU Boost essentially looks at power being consumed by games / applications and adjusts the GPU accordingly, taking into account environmental conditions like GPU temperature. Like those technologies, GPU Boost automatically boosts GPU clock speed to increase performance. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device.In addition to introducing a new graphics card based on new GPU, NVIDIA is also unveiling a number of new features and capabilities coming with the GeForce GTX 680, namely GPU Boost, Adaptive VSync, TXAA, NVENC and Bindless Textures.Īs you can probably surmise by its name, GPU Boost is somewhat akin to the Turbo Boost and Turbo Core technologies in today’s Intel and AMD processors.
This device has no display connectivity, as it is not designed to have monitors connected to it. The GPU is operating at a frequency of 719 MHz, which can be boosted up to 758 MHz, memory is running at 900 MHz (3.6 Gbps effective).īeing a mxm module card, the NVIDIA GeForce GTX 680M does not require any additional power connector, its power draw is rated at 100 W maximum. NVIDIA has paired 4 GB GDDR5 memory with the GeForce GTX 680M, which are connected using a 256-bit memory interface. It features 1344 shading units, 112 texture mapping units, and 32 ROPs.

Unlike the fully unlocked GeForce GTX 680 Mac Edition, which uses the same GPU but has all 1536 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 680M to reach the product's target shader count. The GK104 graphics processor is an average sized chip with a die area of 294 mm² and 3,540 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GK104 graphics processor, in its N13E-GTX-A2 variant, the chip supports DirectX 12. The GeForce GTX 680M was a mobile graphics chip by NVIDIA, launched on June 4th, 2012.
