Is intel's RdRand TRNG or PRNG?

I've searched the net for quite a while and couldn't find a definitive answer. I want to know the quality of random numbers generated by intel's rdrand instructions. How does it compare to IDQ's cards for example? Is it truly random or pseudo random?

Thanks

Please read John M's articles and code samples https://software.intel.com/en-us/articles/intel-digital-random-number-generator-drng-software-implementation-guide section 2.2 covers pseudo and 2.3 covers true
