At 333 MHz, it has a peak pixel fill-rate of 1332 megapixels per second. It operates at a clock rate ranging from 160 to 333 MHz, depending on the particular chipset. It is a 4 pixel per clock cycle design supporting DirectX 9 pixel shader model 2.0. The 3D architecture of the GMA 900 was a significant upgrade from the previous Extreme 3D graphics processors. The GMA 900 was the first graphics core produced under Intel's Graphics Media Accelerator product name, and was incorporated in the Intel 910G, 915G, and 915Gx chipsets. Intel has begun working on a new series of discrete (non-integrated) graphics hardware products, under the codename Larrabee. Intel used the low-power PowerVR MBX designs in chipsets supporting their XScale platform, and since the sale of XScale in 2006 has licensed the PowerVR SGX and used it in the GMA 500 IGP for use with their Atom platform. While GMA performance has been widely criticized in the past as being too slow for computer games, the latest GMA generation should ease many of those concerns for the casual gamer.ĭespite similarities, Intel's main series of GMA IGPs is not based on the PowerVR technology Intel licensed from Imagination Technologies. Many of the advantages of the new GMA architecture come from the ability to flexibly switch as needed between executing graphics-related tasks or video-related tasks. The 4th generation of GMA combines fixed function capabilities with a threaded array of programmable executions units, providing advantages to both graphics and video performance. However, with the introduction of Intel’s 4th generation of GMA architecture ( GMA X3000) in 2006, many of the functions are now built into the hardware, providing an increase in performance. The original architecture of GMA systems supported only a few functions in hardware, and relied on the host CPU to handle at least some of the graphics pipeline, further decreasing performance. Later, Intel integrated the i740 core into the Intel 810 chipset. The GMA line of GPUs replaces the earlier "Intel Extreme Graphics", and the Intel740 line, which were discrete units in the form of AGP and PCI cards. 6.2 Comparison of performance between Intel's GMA 3100, software rendering based Swiftshader and the Geforce 8 series.6 Microsoft Windows performance reviews.
