Subpixel rendering is a method used to increase the effective resolution of a color display device. It takes advantage of each pixel 's composition of individually addressable red, green, and blue components adjacent on the display matrix, called subpixels , and uses them as rendering units instead of pixels.
Eric's Pixel Expansion (EPX) is an algorithm developed by Eric Johnston at LucasArts around 1992, when porting the SCUMM engine games from the IBM PC (which ran at 320 × 200 × 256 colors) to the early color Macintosh computers, which ran at more or less double that resolution. [5]
Metal is a low-level, low-overhead hardware-accelerated 3D graphic and compute shader API created by Apple, debuting in iOS 8. Metal combines functions similar to OpenGL and OpenCL in one API. It is intended to improve performance by offering low-level access to the GPU hardware for apps on iOS, iPadOS, macOS, and tvOS.
Mac OS X 10.4 Tiger supports the GMA 950, since it was used in previous revisions of the MacBook, Mac mini, and 17-inch iMac. [35] It had been used in all Intel-based Mac minis until the Mac mini released on March 3, 2009). [36] Mac OS X 10.5 Leopard contains drivers for the GMA X3100, which were used in a recent revision of the MacBook range. [37]
New state object to enable (mostly) the CPU to change states efficiently. Unified shader model enhances the programmability of the graphics pipeline. It adds instructions for integer and bitwise calculations. The common shader core [48] provides a full set of IEEE-compliant 32-bit integer and bitwise operations. These operations enable a new ...

The fifth generation 3DMark. Like 3DMark03, it is based on DirectX 9 but all of the graphics tests require a minimum hardware support of Shader Model 2.0. [11] While the tests only make use of Shader Model 2.0, by default the highest compilation profile supported by the hardware is used, including 3.0.
The coarse, low-resolution graphics display mode works differently, as it can output a pattern of dots per pixel to offer more color options. These patterns are stored in the character generator ROM and replaces the text character bit patterns when the computer is switched to low-res graphics mode.
