Product Descriptions

NVIDIA Tegra 4i is based on the Tegra 4 architecture and it brings the Tegra 4 super phone  experiences into the mainstream smartphone, and integrates NVIDIA’s LTE i500 SDR modem,  all on a single chip. Tegra 4i includes ARM’s newest and most efficient core— the Cortex-A9 r4 CPU— in a quad-core implementation at 2.3 GHz with a fifth battery saver core, and is half the  size of the competing quad-core integrated LTE mobile processors. Tegra 4i’s new CPU was designed by ARM with help from NVIDIA and sets new standards for  efficiency and performance while being 2x the performance of the previous revision of CortexA9 found in Tegra 3. Tegra 4i delivers super-fast Web browsing and quick load time for apps,  along with great battery life. 

Benchmarking CPU Performance Benchmarks are typically used to evaluate the performance of a device or a design such that  the benchmark results correlate well with the real world performance of the design. Therefore  when evaluating the performance of a CPU architecture, it is essential to ensure that the  workloads used to benchmark the performance of the CPU is similar to those presented by real  world applications and programs.  Over the years several benchmarks have been developed to evaluate the performance of  CPUs. Two of the well-known benchmarks that have been used for CPU benchmarking are Dhrystone MIPS and Coremark. Dhrystone MIPS, also known as DMIPS, is a synthetic  benchmark that was developed about 30 years ago primarily intended to be representative of  CPU integer processing performance.
