Benefits and Disadvantages of Multiple Graphics Cards.
One of the most common causes of poor performance is the GPU support being turned off due to unstable drivers. This causes the game to revert to software rendering, which can cripple performance on low-end devices. The Google Chrome browser provides some diagnostics you can use to check for this on Windows, Mac, Linux and Android devices.

Besides the big difference on the maximum theoretical bandwidth between the CPU and GPU, we were still curious about the real-life performance impact on games by using a PCI Express 3.0 against a.

The GPU-Z can support leading GPU brands such as Intel graphics, AMD, ATI, and NVIDIA, allowing users to validate and document the performance of their product. The software has a simple, user-friendly interface through which it displays information on GPU performance, including default clocks, overclock, and 3D clocks (if available).

GPU Boost continuously monitors power and temperatures, helping your GPU use every bit of performance without exceeding safety or comfort limits.

The CPU (central processing unit) has been called the brains of a PC. The GPU (graphics processing unit) its soul. Over the past decade, however, GPUs have broken out of the boxy confines of the PC. GPUs have ignited a worldwide AI boom. They’ve become a key part of modern supercomputing. They’ve been woven into a sprawling new hyperscale.

Kepler is the codename for a GPU microarchitecture developed by Nvidia, first introduced at retail in April 2012, as the successor to the Fermi microarchitecture. Kepler was Nvidia's first microarchitecture to focus on energy efficiency. Most GeForce 600 series, most GeForce 700 series, and some GeForce 800M series GPUs were based on Kepler, all manufactured in 28 nm.

The Graphics Processing Unit (GPU), found on video cards and as part of display systems, is a specialized processor that can rapidly execute commands for manipulating and displaying images. GPU-accelerated computing offers faster performance across a broad range of design, animation, and video applications. This means you get a big performance boost: Illustrator runs faster and more smoothly.
