GPUs are specialized processors that efficiently handle graphics calculations to complement general-purpose CPUs. GPUs can also accelerate complex computations using GPGPU. For example, the NVIDIA GTX 780 Ti from 2013 had over 5,000 GFLOPS of computational power, making it one of the fastest GPUs, compared to earlier supercomputers like India's fastest in 2003 with 1,000 GFLOPS. When choosing a graphics card, factors to consider include display resolution, the GPU's power, amount and type of memory, cooling design, and factory overclocking.

2. Umm.. GPU??
GPU : Graphics Processing Unit
CPU : Central Processing Unit
GPU complements CPU which performs general
processing, by more efficiently handling Graphics
Calculations.
Can also accelerate Video transcoding, Image
processing and other complex computations using
concept of GPGPU (General-purpose computing on
Graphics Processing Units).
Eg. CUDA (Compute Unified Device Architecture).

3. THEN AND NOW
Intel ASCI Red/9632 : 2,379 GFLOPS
- Fastest Supercomputer (World), 1999
PARAM PADMA : 1,000 GFLOPS
- Fastest Supercomputer (India), 2003
NVIDIA GTX 780 Ti : 5,046 GFLOPS
- Fastest GPU (General), 2013
GFLOPS : Giga FLoating-point Operations Per Second.
A measure of computer performance.

4. Memory is the boss? NO!
GTX 680
(2GB)
GT 430
(4GB)
Memory : 2GB
Memory : 4GB
Price : Rs. 41,195
Price : Rs. 4,520
Computation power : 3,090 GFLOPS
Computation power : 269 GFLOPS

5. WHICH GRAPHIC CARD SHOULD I
BUY?
Deciding factors:•
Display resolution (computation power required).
•
The underlying GPU (computation power you can
get).
•
Amount, Type of memory (DDR3/DDR5).
•
Factory overclock (extra power at same price).
•
Cooling design.

Liquid Cooling.

Air Cooling : Axial, Centrifugal.

Axial : More efficient cooling. Blows waste heat
inside cabinet.

Centrifugal : Lesser efficient cooling. Blows waste
heat outside cabinet.
