(While most Phoronix readers should already be well aware, the reported CPU frequency differences in the system table just come down to the different CPU scaling driver on the different kernels and reporting base vs. Turbo frequency; along with the other reporting differences just come down to how the different drivers/kernels expose their information but it was all maintained during testing.

Nvidia has released some new information surrounding their upcoming 64-bit Tegra K1 variant, codenamed 'Project Denver', discussing the architecture of the chip while also making some bold performance claims.

Diving deeper into the Denver CPU cores, and Nvidia has revealed some info on the architecture being used. Each Denver core uses a seven-way superscalar microarchitecture that's capable of seven operations per clock cycle at best, leading to high throughput when conditions are ideal. During typical usage patterns it's unlikely you'll achieve seven operations per cycle, but it's impressive nevertheless.
