nFORCE PLATFORM PROCESSING
ARCHITECTURE
The NVIDIA nForceTM Platform Processing
Architecture has been designed to address the
needs of today's most demanding users--all of
whom expect unmatched system and memory
performance, stunning 3D graphics, awesome
3D audio, and fast broadband and networking
connections.
To achieve this previously unattainable level
of performance and reduce overall system
latency, it was necessary for NVIDIA to depart
from "traditional" PC platforms and create an
entirely new architecture. In redefining the PC
to deliver unmatched system performance, the
nForce's revolutionary new system architecture
includes:
-- a distributed platform processing design;
-- patent-pending system, memory and
networking technologies for the most efficient
processing and performance;
-- integrated GeForce2 3D graphics and
Dolby
TM
Digital 3D audio.
To achieve this level of unmatched system
performance, nForce is comprised of two
platform processors: the nForce Integrated
Graphics Processor (IGP) and the nForce Media
and Communications Processor (MCP).
nFORCE IGP
The nForce IGP redefines system and
graphics performance. The core of the
nForce IGP is comprised of the
TwinBankTM Memory Architecture; a
Dynamic Adaptive Speculative Pre-
processorTM (DASP) to help boost CPU
performance; an integrated GeForce2
GPU for an uncompromised 3D visual
experience; and the AMD Hyper-
TransportTM, a high-performance I/O
bus interface
.
TWINBANK MEMORY
ARCHITECTURE
TwinBank's patent-pending, dual-
independent, crossbar memory controller
allows the CPU and the graphics and audio
sub-systems to access TwinBank's 4.2GB/sec.
of memory bandwidth simultaneously,
allowing users to run multiple applications
concurrently, all without any performance
degredation. Fully scalable, with support for
DDR-266MHz system memory technologies,
TwinBank delivers up to 30% more peak
memory bandwidth than comparable dual-
channel-based RDRAM solutions.
DYNAMIC ADAPTIVE SPECULATIVE
PRE-PROCESSOR(DASP)
NVIDIA's DASP technology dramatically
enhances CPU performance well beyond
other X86 architectures--even those with
substantially higher "published" core
frequencies. DASP applies a patent-pending,
intelligent, pre-processing technology to store
application instructions and data before they
are needed, substantially eliminating the
bottlenecks that occur between memory and
the CPU, and graphics and audio subsystems,
thereby boosting overall system performance
.
GEFORCE2 GPU
Transmitting huge amounts of geometry
data across the AGP bus to create rich,
real-time 3D images and animations
consumes valuable system bandwidth.
Leveraging its success in the graphics world,
nForce integrates the graphics power of the
award-winning GeForce2 GPU. With its
second generation transform and lighting
capabilities, per-pixel shading operations, a
fill rate of up to 350M pixels per second and
an internal 8X AGP interface, the integrated
GeForce2 trounces the graphics performance
of all other integrated graphics solutions.
And, because the entire platform architecture
is scalable, power users have the ability to
override the GeForce2 with even more powerful
NVIDIA GPUs, such as the GeForce3.
AMD HYPERTRANSPORT
With other platforms, the lagging performance
of the PCI bus interface constrains overall
system performance. nForce utilizes AMD's
HyperTransport I/O bus to deliver the highest
continuous throughput--800MB/sec. between
the nForce IGP and MCP platform processors--
ensuring information is relayed through the
entire platform as quickly as possible.
