===Integrated graphics solutions=== '''Integrated graphics solutions''', '''shared graphics solutions''', or '''Integrated graphics processors (IGP)''' utilize a portion of a computer's system RAM rather than dedicated graphics memory. Most are integrated into the motherboard, though exceptions include AMD's IGPs that use dedicated sideport memory on certain motherboards, and [[accelerated processing unit|APUs]], where they are integrated with the [[central processor unit|CPU]] die. Computers with integrated graphics account for 90% of all PC shipments.<ref>[http://www.anandtech.com/mb/showdoc.aspx?i=3111&p=23 AnandTech: Β΅ATX Part 2: Intel G33 Performance Review<!-- Bot generated title -->]</ref> These solutions are less costly to implement than dedicated graphics solutions, but tend to be less capable. Historically, integrated solutions were often considered unfit to play 3D games or run 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.<ref>{{cite web | url = http://www.xbitlabs.com/articles/chipsets/display/int-chipsets-roundup.html | title = Xbit Labs: Roundup of 7 Contemporary Integrated Graphics Chipsets for Socket 478 and Socket A Platforms | author = Tim Tscheblockov | accessdate = 2007-06-03 }}</ref> However, modern integrated graphics processors such as [[AMD Accelerated Processing Unit]] and [[Intel HD Graphics]] are more than capable of handling 2D graphics or low stress 3D graphics, having improved performance that they can match or exceed that of older dedicated graphic cards, although they are still far less capable than current generation dedicated GPUs. As a GPU is extremely memory intensive, an integrated solution may find itself competing for the already relatively slow system RAM with the CPU, as it has minimal or no dedicated video memory. IGPs can have up to 29.856 GB/s of memory bandwidth from system RAM, however graphics cards can enjoy up to 264GB/sec of bandwidth over its memory-bus. Older integrated graphics chipsets lacked hardware transform and lighting, but newer ones include it.<ref>{{cite web | url = http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/Integrated_Graphics_Solutions_white_paper_rev61.pdf | title = Integrated Graphics Solutions for Graphics-Intensive Applications | author = Bradley Sanford | accessdate = 2007-09-02 }}</ref><ref>{{cite web | url = http://www.techspot.com/news/46773-amd-announces-radeon-hd-7970-claims-fastest-gpu-title.html| title = Integrated Graphics Solutions for Graphics-Intensive Applications | author = Bradley Sanford | accessdate = 2007-09-02 }}</ref>
