'''IBM 8514''' is a [[graphics card]] manufactured by [[IBM]] and introduced with the [[IBM PS/2]] line of personal computers in 1987. It supports a [[display resolution]] of {{resx|1024x768}} [[pixel]]s with [[256 colors]] at 43.5&nbsp;[[Hertz|Hz]] ([[Interlaced video|interlaced]]), or {{resx|640x480}} at 60&nbsp;Hz ([[Progressive scan|non-interlaced]]).<ref name="os2museum">{{cite web|url=http://www.os2museum.com/wp/?p=1850 |title=The 8514/A Graphics Accelerator |publisher=OS/2 Museum |date=2013-05-09 |access-date=2014-06-19}}</ref><ref name=":0">{{Cite web |title=8514A |url=http://www.walshcomptech.com/ohlandl/video/8514A.html |access-date=2022-10-26 |website=www.walshcomptech.com}}</ref>  8514 usually refers to the [[display controller]] hardware (such as the 8514/A [[display adapter]]).<ref name=":0" />  However, IBM sold the companion [[CRT monitor]] (for use with the 8514/A) which carries the same designation, 8514.

The 8514 uses a standardised [[API]] called the "Adapter Interface" or AI. This interface is also used by [[XGA]], [[IBM Image Adapter/A]], and clones of the 8514/A and XGA such as the [[ATI Technologies]] [[ATI Mach|Mach series]] and [[8x8|IIT]] ''AGX''. The interface allows computer software to offload common [[2D computer graphics|2D-drawing]] operations ([[line-draw]], [[color-fill]], and block copies via a [[blitter]]) onto the 8514 hardware. This frees the host [[CPU]] for other tasks, and greatly improves the speed of redrawing a graphics visual (such as a [[pie-chart]] or [[CAD]]-illustration).

The 8514 initially sold for $1290 for the adapter and $270 for the 512{{nbsp}}KB memory expansion (equivalent to ${{Inflation|US|1290|1987|r=-2}} and ${{Inflation|US|270|1987|r=-1}}, respectively, in {{Inflation/year|US}}).{{Inflation/fn|US}} The 8514/A required a [[Micro Channel architecture]] bus at a time when [[Industry Standard Architecture|ISA]] systems were standard.

==History==
The 8514 was introduced with the [[IBM PS/2]] computers in April 1987. It was an optional upgrade to the [[Micro Channel architecture]] based PS/2's [[Video Graphics Array]] (VGA), and was delivered within three months of PS/2's introduction.

Although not the first PC video card to support [[hardware acceleration]], IBM's 8514 is often credited{{by whom|date=December 2016}} as the first PC mass-market [[fixed-function]] accelerator. Up until the 8514's introduction, PC graphics acceleration was relegated to expensive [[workstation]]-class, graphics [[coprocessor]] boards. [[Coprocessor]] boards (such as the [[Truevision TGA|TARGA]] Truevision series) were designed around special CPU or [[digital signal processor]] chips which were programmable. Fixed-function accelerators, such as the 8514, sacrificed programmability for better cost/performance ratio.{{citation needed|date=December 2016}}

Later compatible 8514 boards were based on the [[Texas Instruments]] [[TMS34010]] chip.{{citation needed|date=December 2016}}

Even though the 8514 was not a best-seller, it created a market for fixed-function PC graphics accelerators which grew exponentially in the early 1990s. {{citation needed|date=December 2016}}

The ''[[ATI Mach series|ATI Mach]] 8'' and ''Mach 32'' chips were popular [[Clone (computing)|clones]], and several companies (notably [[S3 Graphics|S3]]) designed graphics accelerator chips which were not register compatible but were conceptually very similar to the 8514/A.<ref name="google">{{Cite news |last1=Córdova |last2=Zelnick |date=June 11, 1991 |title=$520 Adapter Marries 8514/A, TIGA Graphics |pages=58 |work=PC Magazine |url=https://archive.org/details/bub_gb_LNhQLiJ8TgQC/page/n67/mode/2up}}</ref>

The 8514 was superseded by IBM [[XGA]]. 

The [[Video Electronics Standards Association|VESA]] Group introduced a common standardized way to access features like hardware cursors, Bit Block transfers ([[Bit blit|Bit Blt]]), off screen [[Sprite (computer graphics)|sprites]], hardware panning, drawing and other functions with [[VESA_BIOS_Extensions#VBE/accelerator_functions_(VBE/AF)_(August_1996)|VBE/accelerator functions (VBE/AF)]] in August 1996.

==Output capabilities==
The 8514 offered:
*'''{{resx|640×480}}''' graphics with 256 colors out of 262,144 ([[List_of_monochrome_and_RGB_color_formats#18-bit_RGB|18 bit RGB]]); text mode with 80×34 characters;
*'''{{resx|1024×768}}''' graphics with 256 colors out of 262,144 (18 bit RGB); text mode with 85×38 or 146×51 characters;

Latter clone board offered additional resolutions:{{citation needed|date=December 2016}}
*'''{{resx|800×600}}''' with [[High color|16-bit]] and [[Color depth#True color (24-bit)|24-bit color depths]]

In the late 1980s, several companies cloned the 8514/A often for the ISA bus. Notable among those was [[Western Digital]] Imaging's ''PWGA-1'' (also known as the ''WD9500'' chip set), the [[Chips and Technologies|Chips & Technologies]] ''82C480'', and [[ATI Technologies|ATI's]] ''[[ATI Mach series|Mach8]]'' and later ''Mach32'' chips. In one way or another, the clones were all better than the original with more speed, enhanced drawing functionality and overall improved video mode selections. Clone support for non-interlaced modes at resolutions like 800×600 and 1280×1024 was typical, and all clones had longer command queues for increased performance.
