Есть ли какие то ещё отличия GMA900 от 945? |
первый кушает до 128mb а второй 256.
оба семейства Intel® DVMT 3.0

GMA 900
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.
The 3D architecture of the GMA 900 was a significant upgrade from the previous Extreme 3D graphics processors. It is a 4 pixel per clock cycle design supporting DirectX 9 pixel shader model 2.0. It operates at a clock rate ranging from 160 to 333 MHz, depending on the particular chipset. At 333 MHz, it has a peak pixel fill-rate of 1332 megapixels per second. However, the architecture still lacks support for hardware transform and lighting and the similar vertex shader technologies.
Like previous Intel integrated graphics parts, the GMA 900 has hardware support for MPEG-2 motion compensation, color-space conversion and DirectDraw overlay.
The processor uses different separate clock generators for display and render cores. The display unit includes a 400 MHz RAMDAC, 2 25 - 200 Mpixel/s serial DVO ports, and 2 display controllers. In mobile chipsets, up to 2 18-bit 25 - 112 MHz LVDS transmitters are included.
[edit] GMA 950
The GMA 950 is Intel's second-generation graphics core, which was also referred by Intel as 'Gen 3.5 Integrated Graphics Engine' in datasheets. It is used in the Intel 940GML, 945G, 945GU and 945GT system chipsets. The amount of video-decoding hardware has increased; VLD, iDCT, and dual video overlay windows are now handled in hardware[citation needed]. The maximum core clock is up to 400 MHz (on Intel 945G, 945GC, 945GZ, 945GSE), boosting pixel fill-rate to a theoretical 1600 megapixels/s.
The GMA 950 shares the same architectural weakness as the GMA 900: no hardware geometry processing. Neither basic (DX7) hardware transform and lighting,[2] nor more advanced vertex shaders (DX8 and later) are handled in the GMA hardware.
[edit] GMA 3000
The 946GZ, Q965 and Q963 chipsets use GMA 3000.[3][4] The GMA 3000 3D core is very different from the X3000, despite similar names. It is based more directly on the previous generation GMA 900 and GMA 950 graphics, and belonging to the same "i915" family with them. It has pixel and vertex shaders which only supports shader model 2.0 features, and the vertex shaders are still only software provided. In addition, hardware video acceleration such as hardware-based iDCT computation, ProcAmp (video stream independent color correction), VC-1 decoding are not implemented in hardware. Of the GMA 3000-equipped chipsets, only Q965 retains dual independent display support. The core speed is rated 400 MHz with 1.6 Gpixel/s fill rate in datasheets, but was listed as 667 MHz core in white paper.[5]
Memory controller can now address maximum 256 MB memory and the integrated serial DVO ports has increased top speed to 270Mpixel/s. |

Dosaev, в аглицком я не силён.
128 и 256. это от оперативки для видео?
если да, то будет PCI внешняя видяха стоять.
на моём атоме 330
частота проца 1.6ГГц
Оперативка одим слотом 2Гига
SATA катастрофически не хватает, всего два
Стоит винт SATA от бука
Стоит SATA DVD привод тоже от бука.
(извратился врезать привод и картридер в место одного орбычного DVD привода)
на 6020 проц можно поставить 3ГГц
два слота, жаль что по одному гигу
SATA 4 что вполне хватает - для создания масива и просто подвешиванием дополнительного винта.. |
