A top to bottom GPU refresh
Nvidia today splashed the mobile market with more than half a dozen new GPUs comprising the company's GeForce GTX 800M Series. This is a top to bottom release, meaning the new GPUs range from entry-level (GeForce 830M) all the way up to what Nvidia claims is the fastest mobile graphics chip in the world, the GeForce GTX 880M. The new releases join Nvidia's already available 820M GPU.
According to Nvidia, the new GPUs are 30 percent, 40 percent, and even 60 percent (in some cases) faster than its previous generation of mobile GPUs, and none more burly than the 880M. Nvidia's flagship part is based on Kepler (not Maxwell) and features 1,536 CUDA cores and 128 TMUs. It has a core clockspeed of 954MHz and supports up to 4GB of GDDR5 memory clocked at 5,000MHz (effective) on a 256-bit memory bus.
This release isn't solely focused on speed, however, as Nvidia points out that its Battery Boost technology is one of several new feature additions. This one in particular is supposed to be able to deliver up to twice the gaming battery life when enabled.
"Here’s how it works: instead of your notebook pushing every component to its max, Battery Boost targets a user defined frame rate, such as 30 FPS. The driver level governor takes over from there, and operates all your system components, including CPU, GPU, and memory at peak efficiency, while maintaining a smooth, playable experience," Nvidia explains in a blog post .
More details on the GeForce 830M, 840M, GTX 850M, GTX 860M, GTX 870M, and GTX 880M are available on Nvidia's website .
