Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Dual-ported video RAM (VRAM) is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters. Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Both the iPhone 8 and 8 Plus were supplied with iOS 11 on launch, [25] [27] and support iOS 12, iOS 13, iOS 14, iOS 15 and iOS 16. Apple announced that the iPhone 8 and 8 Plus, as well as the iPhone X, would not support iOS 17 due to hardware limitations. [35] However, the devices still receive security updates.
Graphics DDR SDRAM (GDDR SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) specifically designed for applications requiring high bandwidth, [1] e.g. graphics processing units (GPUs).
The second-generation iPhone SE's camera hardware is the same as the iPhone 8, but adds Portrait mode, Portrait lighting, Smart HDR, extended dynamic range for video up to 30 fps, stereo recording and cinematic video stabilization. The iPhone 12 and 12 Pro series brought Night Mode to all camera lenses, including the TrueDepth camera. It also ...
As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14] The M3 Pro and 14-core M3 Max have lower memory bandwidth than the M1/M2 Pro and M1/M2 Max respectively.

1: 32-bit is really (8:8:8:8), but the final 8-bit number is an "empty" alpha channel. It is otherwise equal to 24-bit colour. Many GPUs use 32-bit colour mode instead of 24-bit mode merely for faster video memory access through 32-bit memory alignment. VGA= 864 [ 352 (0160h)] also appears to select 1280 ×800 (8-bit) for various laptops' displays.
