Abstract: When XGI Technology announced the Volari line of graphics processors for the desktop and mobile market on September 15th, the collective response from the PC community was..."Wha...?" |

BroadBahn Memory Architecture
Memory Architecture is XGI Technology's
proprietary memory architecture. According to XGI, it uses compression
algorithms to increase the amount of data flowing between the GPU and the
according to the company, the Broadbahn memory architecture consists of 4x32-bit channels
carrying data to and from the DRAM. Internally, the
card uses four separate buses, as you can see in the diagram above, each capable
of accessing the four memory channels independently.
Essentially then, each separate memory-requiring component of the
card has a 4x32 bit channel to the memory. XGI claims that this provides and
effective 512-bit internal memory channel, increasing efficiency.
The Volari V8 processors
take advantage of XGI's BroadBahn memory architecture, leverage compression-based algorithms to
the ultimate end of effectively doubling the
amount of data flowing to and from the DRAM. This helps optimize 3D
rendering, image processing and media streaming applications.
is another one of XGI's newly christened technologies. Again, no other specifics are
available, but if you reverse engineer the paragraph below, it sounds like the
Volari GPUs clock themselves down to save
power when handling less demanding applications.
"Not all processing
environments are created equal. The blistering demands imposed by full screen 3D
applications will tax your GPU for all it's worth, leaving weaker processors in
the dust. When it's time to pour on the muscle, V-Drive is like a short of pure
adrenaline in the heat of the battle. V-Drive™ ratchets up processing power in
perfectly timed response to computational demands, effortlessly delivering full
frame graphics with flawless execution. Shift in to V-Drive™ and experience the
ultimate in high-speed performance."
