KEPLER - THE WORLD'S FASTEST, 
MOST EFFICIENT HPC ARCHITECTURE

Get 3x the performance with the NVIDIA® Kepler, the world's fastest and most efficient high performance computing (HPC) architecture. With innovative computing technology and features, it is applicable to a broader range of scientific computing applications and makes hybrid computing more accessible for application developers and researchers.

Kepler's break-through performance is made possible by:

SMX
Delivers more processing performance and efficiency through this new, innovative streaming multiprocessor design that allows a greater percentage of space to be applied to processing cores versus control logic

 

 

Dynamic Parallelism
Simplifies GPU programming by allowing programmers to easily accelerate all parallel nested loops – resulting in a GPU dynamically spawning new threads on its own without going back to the CPU

 

Read the Dynamic Parallelism White Paper

 

Hyper-Q
Slashes CPU idle time by allowing multiple CPU cores to simultaneously utilize a single Kepler GPU, dramatically advancing programmability and efficiency
