Nvidia RTX 3080 Breakdown

The GeForce RTX 3080 Ti and RTX 3080 graphics cards deliver the ultra performance that gamers crave, powered by Ampere—NVIDIA’s 2nd gen RTX architecture. They are built with enhanced RT Cores and Tensor Cores, new streaming multiprocessors, and superfast G6X memory for an amazing gaming experience.


Just introduced in the above, it is designed for rapidly manipulate and alter memory.

Video Memory

Video memory capacity varies from 2 GB to 32 GB and even larger in modern times. Since the video memory needs to be accessed by the display circuitry and the GPU, it usually make use of high-speed or multi-port memory like VRAM (video RAM), WRAM (Windows RAM) and SGRAM (synchronous graphics RAM).

Video BIOS

Video BIOS contains a minimal program for the initial setup as well as control of the graphics card. It might also contain info on the operating speeds, memory timing and voltages of the RAM (random access memory), graphics processor and other information which can be changed.

RAMDAC (RAM digital-to-analog converter)

The RAMDAC is a kind of RAM chip which regulates the functioning of the graphics card. It converts digital signals to analog signals for computer displays which adopt analog inputs like CRT (cathode ray tube) displays. Since digital computer displays become more and more popular, the RAMDACs are beginning to disappear from video cards.

Motherboard Interface

Motherboard interface is a connection system between motherboard and video card. With the time goes by, there are many different motherboard interfaces, such as S-100 bus, PCI, USB, PCI-X and PCI Express.

Output Interfaces

The following are the common connection systems between the graphics card and the display device.

1. VGA (video graphics array) (DE-15)

VGA is also called D-sub or VGA Connector. It is an analog-based standard for CRT displays.

2. DVI (digital visual interface)

DVI is a digital-based standard special for displays like flat-panel displays (LCDs, HD TV displays and plasma screens) and video projectors.

3. VIVO (video in video out) for S-Video, composite video & Component video
4. HDMI (high-definition multimedia interface)


HDMI is a compact video/audio interface. It can transfer compressed or uncompressed digital audio data from an HDMI-compliant device (source device) to compatible digital audio devices, digital TVs, computer monitors or video projectors. It can also do the same transmission to the uncompressed video data. Actually, HDMI is a digital replacement to the analog video standards.

5. DisplayPort

DisplayPort is a digital display interface to connect a video source to a display device. It can also transfer audio, USB and other sort of data. The DisplayPort is designed to replace VGA, but finally it is compatible with VGA to complement it instead of replacing it.

Heat Sink

A heat sink is a copper pipe used to dissipate the heat which is produced by the GUP. Usually, there is a fan equipped to cool the sink as well as the GPU. Not all graphics cards get rid of the heat by heat sink. For instance, some old cards use liquid (water) to cool themselves. Yet, most modern graphics cards have heat sinks.
