Another Double Decker Woah! Shared memory – The video chipset on the motherboard uses some of the system RAM for the video memory. The NV2 used the same rendering method and was never completed. Video memory may be used for storing other data as well as the screen image, such as the Z-buffer, which manages the depth coordinates in 3D graphics, textures, vertex buffers, and compiled shader programs. While CPU and power supply makers have recently moved toward higher efficiency, power demands of GPUs have continued to rise, so the video card may be the biggest electricity user in a computer.

Shared and dedicated I would guess are on the circuit board usually not the best.

This is usually because the video card has a very thick cooling system. The NV40 was powerful, but its million transistors limited fabrication yields and increased the price, so the two cards built from it, the GeForce andhad only moderate success.

Dedicated vs Shared Memory. Used but working card. Hi Sheldon, The “shared” memory means that the integrated video uses the same RAM memory that all your other applications use. The video RAM settings of the virtual machine will not affect this. The graphics card is in itself a small PC dedicated to o/bb applications, independent of the rest of the PC, the only link being the information passing through the port graphic and food.


Some problems of this standard are electrical noise, image distortion and sampling error evaluating pixels. You May Also Like. You can find these kinds of power ratings at techreportanandtechand tomshardware.

The machine I built, which runs Ubuntu 7. The name, type and amount of video memory the card has will be listed. Sheldon, I have been in your shoes before, and admittedly confused by the options. These require a RAMDAC, but they reconvert the analog signal back to digital before they can display it, with the unavoidable loss of quality stemming from this digital-to-analog-to-digital conversion.

o/g All binary grousing aside, larger numbers means that it has faster video RAM. This table column provides the video outputs included on the standard configuration for this video card. Discrete memory means the memory is separate and, indeed, it has to be on the graphics card, where else? DirectX This table column gives the version of DirectX that this video card was designed to support. Mv Late High Flyer Out of the way!

So, for example [an extreme example], o/h you have meg of system memory e. The more the video card has the better the graphics specially for games or graphic intensive applications such as PhotoShop which is used for picture manipulation ob how the pictures look and other effects that can be applied to them.

Low idle power consumption, moderate power consumption under load, and low production costs complements of what the company called its Sweet Spot strategy meant economical gains for ATI already vgw of AMD by this point. Some FX cards had a bit bus instead of bit and a slower memory clock frequency MHz instead of MHz.

Included is the video card and the dongle which provides output to two DVI displays. In the current world of multiple video standards you have to find out specifically what resolutions, color depths and refresh rates each card supports.

While normally I only recommend Mac 128/2556, I understand your budget situation.
