Each EU contains 2 x 128-bit FPUs. One supports 32-bit and 64-bit integer, FP16, FP32, FP64, and transcendental math functions, and the other supports only 32-bit and 64-bit integer, FP16 and FP32. Thus the FP16 (or 16-bit integer) FLOPS is twice the FP32 (or 32-bit integer) FLOPS.
Intel has released production version drivers for 32-bit and 64-bit Windows Vista that enable the Aero graphics. Intel introduced DirectX 10 for the X3100 and X3500 GPUs in the Vista 15.9 drivers in 2008, though any release of DX10 drivers for the X3000 is uncertain.
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.
Nvidia's proprietary driver, Nvidia GeForce driver for GeForce, is available for Windows x86/x86-64, Linux x86/x86-64/ARM, OS X 10.5 and later, Solaris x86/x86-64 and FreeBSD x86/x86-64. A current version can be downloaded from the Internet, and some Linux distributions contain it in their repositories.
Core i5 processor with integrated HD Graphics 2000. Intel Graphics Technology [4] (GT) [a] is the collective name for a series of integrated graphics processors (IGPs) produced by Intel that are manufactured on the same package or die as the central processing unit (CPU).
A 64-bit channel was once proposed as an optional standard for AGP 3.0 in draft documents, [18] but it was dropped in the final version of the standard. The standard allows 64-bit transfer for AGP8× reads, writes, and fast writes; 32-bit transfer for PCI operations.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
32-bit x86 processors themselves have two legacy modes: real mode and virtual 8086 mode. Real mode causes the processor to mostly act as if it was an original 8086, while virtual 8086 mode allows the creation of a virtual machine to allow the running of programs that require real mode in order to run under a protected mode environment.
