“CPU ray tracing has received tremendous speed ups in the past decade, with works on acceleration structures, traversal algorithms, and packet (or frustum) traversal. While these advancements brought ray tracing into the real-time area, the speed is still generally not acceptable.
PowerVR presents a solution, which proposes to place a small dedicated hardware ray traversal engine (RTE) directly on the GPU die.
The RTE has been confirmed to run at frequencies above 2GHz and can fit into an area less than 15mm2, achieving performance of over 1000 million rays per second.”
UPDATE: As pointed out by Tomas in the comments, the article is apparently a hoax. Too bad, but thanks to Tomas for clearing this up!
All the numbers in the hoax article (2 Ghz, 15 mm2, 1000 million rays/sec) are pulled straight from the paper by Tomas Davidovic entitled "Performance Considerations When Using a Dedicated Ray Traversal Engine" (http://www.davidovic.cz/wiki/lib/exe/fetch.php/school/davidovic_wscg2011/davidovic_wscg2011.pdf)
except that the paper mentions 100 million rays/sec for the RTE instead of 1000 million rays/sec.
Very pathetic journalism, this article would fit much better at a site like semi-accurate where you know beforehand you're reading trash).
