In 1988, the first dedicated polygonal 3D graphics boards were introduced in arcades with the Namco System 21 and Taito Air System. IBM introduced its proprietary Video Graphics Array (VGA) display standard in 1987, with a maximum resolution of 640×480 pixels. In November 1988, NEC Home Electronics announced its creation of

624-403: A fixed amount (e.g. for address generation unit ). One way to implement a barrel shifter is as a sequence of multiplexers where the output of one multiplexer is connected to the input of the next multiplexer in a way that depends on the shift distance. A barrel shifter is often used to shift and rotate n-bits in modern microprocessors, typically within a single clock cycle . For example, take

702-416: A four-bit barrel shifter, with inputs A, B, C and D. The shifter can cycle the order of the bits ABCD as DABC , CDAB , or BCDA ; in this case, no bits are lost. That is, it can shift all of the outputs up to three positions to the right (and thus make any cyclic combination of A, B, C and D). The barrel shifter has a variety of applications, including being a useful component in microprocessors (alongside

780-657: A highly customizable function block and did not really "run" a program. Many of these disparities between vertex and pixel shading were not addressed until the Unified Shader Model . In October 2002, with the introduction of the ATI Radeon 9700 (also known as R300), the world's first Direct3D 9.0 accelerator, pixel and vertex shaders could implement looping and lengthy floating point math, and were quickly becoming as flexible as CPUs, yet orders of magnitude faster for image-array operations. Pixel shading

The most common implementations of this are ATI's HyperMemory and Nvidia's TurboCache . Hybrid graphics cards are somewhat more expensive than integrated graphics, but much less expensive than dedicated graphics cards. They share memory with

1092-522: A specific use, real-time 3D graphics, or other mass calculations: Dedicated graphics processing units uses RAM that is dedicated to the GPU rather than relying on the computer’s main system memory. This RAM is usually specially selected for the expected serial workload of the graphics card (see GDDR ). Sometimes systems with dedicated discrete GPUs were called "DIS" systems as opposed to "UMA" systems (see next section). Dedicated GPUs are not necessarily removable, nor does it necessarily interface with

1170-603: A variety of imitators: by 1995, all major PC graphics chip makers had added 2D acceleration support to their chips. Fixed-function Windows accelerators surpassed expensive general-purpose graphics coprocessors in Windows performance, and such coprocessors faded from the PC market. Throughout the 1990s, 2D GUI acceleration evolved. As manufacturing capabilities improved, so did the level of integration of graphics chips. Additional application programming interfaces (APIs) arrived for

1248-538: A variety of tasks, such as Microsoft's WinG graphics library for Windows 3.x , and their later DirectDraw interface for hardware acceleration of 2D games in Windows 95 and later. In the early- and mid-1990s, real-time 3D graphics became increasingly common in arcade, computer, and console games, which led to increasing public demand for hardware-accelerated 3D graphics. Early examples of mass-market 3D graphics hardware can be found in arcade system boards such as

1326-712: Is commonly referred to as "GPU accelerated video decoding", "GPU assisted video decoding", "GPU hardware accelerated video decoding", or "GPU hardware assisted video decoding". Recent graphics cards decode high-definition video on the card, offloading the central processing unit. The most common APIs for GPU accelerated video decoding are DxVA for Microsoft Windows operating systems and VDPAU , VAAPI , XvMC , and XvBA for Linux-based and UNIX-like operating systems. All except XvMC are capable of decoding videos encoded with MPEG-1 , MPEG-2 , MPEG-4 ASP (MPEG-4 Part 2) , MPEG-4 AVC (H.264 / DivX 6), VC-1 , WMV3 / WMV9 , Xvid / OpenDivX (DivX 4), and DivX 5 codecs , while XvMC

Technologies such as Scan-Line Interleave by 3dfx, SLI and NVLink by Nvidia and CrossFire by AMD allow multiple GPUs to draw images simultaneously for a single screen, increasing the processing power available for graphics. These technologies, however, are increasingly uncommon; most games do not fully use multiple GPUs, as most users cannot afford them. Multiple GPUs are still used on supercomputers (like in Summit ), on workstations to accelerate video (processing multiple videos at once) and 3D rendering, for VFX , GPGPU workloads and for simulations, and in AI to expedite training, as

1482-757: Is often used for bump mapping , which adds texture to make an object look shiny, dull, rough, or even round or extruded. With the introduction of the Nvidia GeForce 8 series and new generic stream processing units, GPUs became more generalized computing devices. Parallel GPUs are making computational inroads against the CPU, and a subfield of research, dubbed GPU computing or GPGPU for general purpose computing on GPU , has found applications in fields as diverse as machine learning , oil exploration , scientific image processing , linear algebra , statistics , 3D reconstruction , and stock options pricing.

1716-457: Is the case with Nvidia's lineup of DGX workstations and servers, Tesla GPUs, and Intel's Ponte Vecchio GPUs. Integrated graphics processing units (IGPU), integrated graphics , shared graphics solutions , integrated graphics processors (IGP), or unified memory architectures (UMA) use a portion of a computer's system RAM rather than dedicated graphics memory. IGPs can be integrated onto a motherboard as part of its northbridge chipset, or on

1794-531: The ALU ). The very fastest shifters are implemented as full crossbars, in a manner similar to the 4-bit shifter depicted above, only larger. These incur the least delay, with the output always a single gate delay behind the input to be shifted (after allowing the small time needed for the shift count decoder to settle; this penalty, however, is only incurred when the shift count changes). These crossbar shifters require however n gates for n -bit shifts. Because of this,

1872-609: The GeForce 256 as "the world's first GPU". It was presented as a "single-chip processor with integrated transform, lighting, triangle setup/clipping , and rendering engines". Rival ATI Technologies coined the term " visual processing unit " or VPU with the release of the Radeon 9700 in 2002. The AMD Alveo MA35D features dual VPU’s, each using the 5 nm process in 2023. In personal computers, there are two main forms of GPUs. Each has many synonyms: Most GPUs are designed for

1950-517: The Intel Core line and with contemporary Pentiums and Celerons. This resulted in a large nominal market share, as the majority of computers with an Intel CPU also featured this embedded graphics processor. These generally lagged behind discrete processors in performance. Intel re-entered the discrete GPU market in 2022 with its Arc series, which competed with the then-current GeForce 30 series and Radeon 6000 series cards at competitive prices. In

2028-465: The PowerVR and the 3dfx Voodoo . However, as manufacturing technology continued to progress, video, 2D GUI acceleration, and 3D functionality were all integrated into one chip. Rendition 's Verite chipsets were among the first to do this well. In 1997, Rendition collaborated with Hercules and Fujitsu on a "Thriller Conspiracy" project which combined a Fujitsu FXG-1 Pinolite geometry processor with

2106-522: The Sega Model 1 , Namco System 22 , and Sega Model 2 , and the fifth-generation video game consoles such as the Saturn , PlayStation , and Nintendo 64 . Arcade systems such as the Sega Model 2 and SGI Onyx -based Namco Magic Edge Hornet Simulator in 1993 were capable of hardware T&L ( transform, clipping, and lighting ) years before appearing in consumer graphics cards. Another early example

2184-616: The Video Electronics Standards Association (VESA) to develop and promote a Super VGA (SVGA) computer display standard as a successor to VGA. Super VGA enabled graphics display resolutions up to 800×600 pixels , a 36% increase. In 1991, S3 Graphics introduced the S3 86C911 , which its designers named after the Porsche 911 as an indication of the performance increase it promised. The 86C911 spawned

2262-412: The motherboard by means of an expansion slot such as PCI Express (PCIe) or Accelerated Graphics Port (AGP). They can usually be replaced or upgraded with relative ease, assuming the motherboard is capable of supporting the upgrade. A few graphics cards still use Peripheral Component Interconnect (PCI) slots, but their bandwidth is so limited that they are generally used only when a PCIe or AGP slot

2340-465: The rotation and translation of vertices into different coordinate systems . Recent developments in GPUs include support for programmable shaders which can manipulate vertices and textures with many of the same operations that are supported by CPUs , oversampling and interpolation techniques to reduce aliasing , and very high-precision color spaces . Several factors of GPU construction affect

2418-483: The 1970s, the term "GPU" originally stood for graphics processor unit and described a programmable processing unit working independently from the CPU that was responsible for graphics manipulation and output. In 1994, Sony used the term (now standing for graphics processing unit ) in reference to the PlayStation console's Toshiba -designed Sony GPU . The term was popularized by Nvidia in 1999, who marketed

2496-594: The 1970s. In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scanned out on the monitor. A specialized barrel shifter circuit helped the CPU animate the framebuffer graphics for various 1970s arcade video games from Midway and Taito , such as Gun Fight (1975), Sea Wolf (1976), and Space Invaders (1978). The Namco Galaxian arcade system in 1979 used specialized graphics hardware that supported RGB color , multi-colored sprites, and tilemap backgrounds. The Galaxian hardware

Specialized processing cores on some modern workstation's GPUs are dedicated for deep learning since they have significant FLOPS performance increases, using 4×4 matrix multiplication and division, resulting in hardware performance up to 128 TFLOPS in some applications. These tensor cores are expected to appear in consumer cards, as well. Many companies have produced GPUs under

2652-422: The 3D hardware, today's GPUs include basic 2D acceleration and framebuffer capabilities (usually with a VGA compatibility mode). Newer cards such as AMD/ATI HD5000–HD7000 lack dedicated 2D acceleration; it is emulated by 3D hardware. GPUs were initially used to accelerate the memory-intensive work of texture mapping and rendering polygons. Later, units were added to accelerate geometric calculations such as

2730-698: The CPU for relatively slow system RAM, as it has minimal or no dedicated video memory. IGPs use system memory with bandwidth up to a current maximum of 128 GB/s, whereas a discrete graphics card may have a bandwidth of more than 1000 GB/s between its VRAM and GPU core. This memory bus bandwidth can limit the performance of the GPU, though multi-channel memory can mitigate this deficiency. Older integrated graphics chipsets lacked hardware transform and lighting , but newer ones include it. On systems with "Unified Memory Architecture" (UMA), including modern AMD processors with integrated graphics, modern Intel processors with integrated graphics, Apple processors,

These chips were essentially previous-generation 2D accelerators with 3D features bolted on. Many were pin-compatible with the earlier-generation chips for ease of implementation and minimal cost. Initially, 3D graphics were possible only with discrete boards dedicated to accelerating 3D functions (and lacking 2D graphical user interface (GUI) acceleration entirely) such as

3042-573: The PS5 and Xbox Series (among others), the CPU cores and the GPU block share the same pool of RAM and memory address space. This allows the system to dynamically allocate memory between the CPU cores and the GPU block based on memory needs (without needing a large static split of the RAM) and thanks to zero copy transfers, removes the need for either copying data over a bus (computing) between physically separate RAM pools or copying between separate address spaces on

This hardware-accelerated video decoding, in which portions of the video decoding process and video post-processing are offloaded to the GPU hardware,

3744-403: The barrel shifter is often implemented as a cascade of parallel 2×1 multiplexers instead, which allows a large reduction in gate count, now growing only with n x log n ; the propagation delay is however larger, growing with log n (instead of being constant as with the crossbar shifter). For an 8-bit barrel shifter, two intermediate signals are used which shifts by four and two bits, or passes

In 1984, Hitachi released ARTC HD63484,

4680-581: The motherboard in a standard fashion. The term "dedicated" refers to the fact that graphics cards have RAM that is dedicated to the card's use, not to the fact that most dedicated GPUs are removable. Dedicated GPUs for portable computers are most commonly interfaced through a non-standard and often proprietary slot due to size and weight constraints. Such ports may still be considered PCIe or AGP in terms of their logical host interface, even if they are not physically interchangeable with their counterparts. Graphics cards with dedicated GPUs typically interface with

4914-519: The one in the PlayStation 2 , which used a custom vector unit for hardware accelerated vertex processing (commonly referred to as VU0/VU1). The earliest incarnations of shader execution engines used in Xbox were not general purpose and could not execute arbitrary pixel code. Vertices and pixels were processed by different units which had their own resources, with pixel shaders having tighter constraints (because they execute at higher frequencies than vertices). Pixel shading engines were actually more akin to

On certain motherboards, AMD's IGPs can use dedicated sideport memory: a separate fixed block of high performance memory that is dedicated for use by the GPU. As of early 2007 computers with integrated graphics account for about 90% of all PC shipments. They are less costly to implement than dedicated graphics processing, but tend to be less capable. Historically, integrated processing

5382-437: The wide vector width SIMD architecture of the GPU. Barrel shifter A barrel shifter is a digital circuit that can shift a data word by a specified number of bits without the use of any sequential logic , only pure combinational logic , i.e. it inherently provides a binary operation . It can however in theory also be used to implement unary operations , such as logical shift left , in cases where limited by

5460-471: Was capable of manipulating graphics hardware registers in sync with the video beam (e.g. for per-scanline palette switches, sprite multiplexing, and hardware windowing), or driving the blitter. In 1986, Texas Instruments released the TMS34010 , the first fully programmable graphics processor. It could run general-purpose code, but it had a graphics-oriented instruction set. During 1990–1992, this chip became

5538-504: Was considered unfit for 3D games or graphically intensive programs but could run less intensive programs such as Adobe Flash. Examples of such IGPs would be offerings from SiS and VIA circa 2004. However, modern integrated graphics processors such as AMD Accelerated Processing Unit and Intel Graphics Technology (HD, UHD, Iris, Iris Pro, Iris Plus, and Xe-LP ) can handle 2D graphics or low-stress 3D graphics. Since GPU computations are memory-intensive, integrated processing may compete with

5616-517: Was during this period of strong Microsoft influence over 3D standards that 3D accelerator cards moved beyond being simple rasterizers to become more powerful general purpose processors as support for hardware accelerated texture mapping, lighting, Z-buffering and compute created the modern GPU. During this period the same Microsoft team responsible for Direct3D and OpenGL driver standardization introduced their own Microsoft 3D chip design called Talisman . Details of this era are documented extensively in

5694-569: Was followed by the Maxwell line, manufactured on the same process. Nvidia's 28 nm chips were manufactured by TSMC in Taiwan using the 28 nm process. Compared to the 40 nm technology from the past, this manufacturing process allowed a 20 percent boost in performance while drawing less power. Virtual reality headsets have high system requirements; manufacturers recommended the GTX 970 and

5772-488: Was originally announced at AMD's CES 2017 presentation on 5 January 2017, alongside the Zen line of CPUs. Vega targets increased instructions per clock , higher clock speeds , and support for HBM2 . AMD's Vega has new memory hierarchy with high-bandwidth cache and its controller. Support for HBM2 featuring double the bandwidth-per-pin over previous generation HBM . HBM2 allows for higher capacities with less than half

5850-737: Was released on 14 August 2017. It included the RX Vega 56 and the RX Vega 64, priced at $ 399 and $ 499 respectively. These were followed by two mobile APUs, the Ryzen 2500U and Ryzen 2700U, in October 2017. February 2018 saw the release of two desktop APUs, the Ryzen 3 2200G and the Ryzen 5 2400G, and the Ryzen Embedded V1000 line of APUs. In September 2018 AMD announced several Vega APUs in their Athlon line of products. Later in January 2019,

5928-498: Was the Nintendo 64 's Reality Coprocessor , released in 1996. In 1997, Mitsubishi released the 3Dpro/2MP , a GPU capable of transformation and lighting, for workstations and Windows NT desktops; ATi used it for its FireGL 4000 graphics card , released in 1997. The term "GPU" was coined by Sony in reference to the 32-bit Sony GPU (designed by Toshiba ) in the PlayStation video game console, released in 1994. In

6006-426: Was the precursor to what is now called a compute shader (e.g. CUDA, OpenCL, DirectCompute) and actually abused the hardware to a degree by treating the data passed to algorithms as texture maps and executing algorithms by drawing a triangle or quad with an appropriate pixel shader. This entails some overheads since units like the scan converter are involved where they are not needed (nor are triangle manipulations even

6084-484: Was widely used during the golden age of arcade video games , by game companies such as Namco , Centuri , Gremlin , Irem , Konami , Midway, Nichibutsu , Sega , and Taito. The Atari 2600 in 1977 used a video shifter called the Television Interface Adaptor . Atari 8-bit computers (1979) had ANTIC , a video processor which interpreted instructions describing a " display list "—the way
