One of the first high-end APU models is a12-9800, Quad core 3.8-4.2ghz,radeon R7 GPU 512 stream processors, thermal design power dissipation 65W. AMD says it can contend with Intel Core i5-6500.

In August, we compared the professional performance and Game Performance of Windows7 and Ubuntu10.04 on a Lenovo Mobile graphics workstation ThinkPadW510. Today, there is no change in Windows 7, Ubuntu has been upgraded to version 10.10, and the development of graphics card hardware and drivers is also changing, it is time to come again. The test platform is a set of 3 D Vision stereo notebook, the main configuration is Corei3-370M2.4GHz dual core

In Linux, the mouse pointer is invisible-Linux general technology-Linux technology and application information. The following is a detailed description. Some machines (more likely nVidia graphics card chips) may not see the mouse pointer after the new system is installed, but the mouse pointer exists and can be used, for example, if you right-click a program or a panel and click the mouse on it, you can see that the program or panel has a response. To display the mouse pointer, you can modify/et

if you have used OpenGL before, you have to write vertices and fragment shader in person (in DirectX, vertex and pixel shader). You will be glad to hear that. the FX file places all the shader code in one place. there are many different pixel shader statement blocks in the FX file to support multiple target configurations) for example, pixel shader 1.1 corresponding to Ge

The following video cards support Double Precision Floating Point: NVIDIA geforce 200 series, 400 series, 500 series graphics cards; amd radeon HD 5800, 5900, 6900 series. The radeon 6900 series does not yet support the official dual-precision floating point number (cl_khr_fp64) extension, so this program also supports cl_amd_fp64 dual-precision floating point extension, w
NVIDIA's public version. As NVIDIA's current next-high-end model, gtx770 is not a strikethrough version of gtx780 in terms of hardware configuration, but is equipped with the gk104 display Core Used by GTX 680, in addition to the high frequency, the memory size is similar to that of gtx680. This gtx770 looks like an "Upgrade" of gtx680 ".

In operations such as image browsing and web page browsing, the advantages of multi-touch are obvious, fast and practical, it provides more cool desktop management and window switching than Windows Vista. In other words, all the features are at your fingertips. This is really great.
