Imagination Technologies is preparing a new high end GPU, but what makes this GPU different however is that it is designed around the principles of real time ray tracing (Life Like 3D) instead of rasterization (Cartooney 3D).

The new GPU is called the "PowerVR RTX" and is not to be confused with the "PowerVR Series 6", a rasterization based architecture which is also currently in development.

4gamer.net has the inside scoop on the "PowerVR RTX" -

I see nothing when I follow that link but a website without any content.

What? It doesn't support CUDA or PhysX! :eek: [/sarc]

This is great if it means another player in the graphics card game. I hope they can come up with something marketable. :thumbsup:

Didn't I just mention this possibility in the competition thread? :eek:

Wouldn't that be cheating? Lets just hope they dont have a driver team that works closely with developers, that would also be cheating. Lets not hope they make a profit , that might also be cheating. :)

Wow ..., they couldn't have picked a sh ttier time to enter the mobile market with the new APU's around. What a waste of resource's.

Sounds like their gambling on "OpenCL" and "OpenRL" (new API for Raytraceing). Its definatly intresting.

They might even have a small edge with the RayTraceing (compaired to Nvidia and AMD). The demo video was not spectacular, but showcased the new tech off alright (enough to make me think, "hmmm" maybe games need this).

If they have engineering samples, that can do roughly ~3x performance of a CPU when it comes to raytraceing, how much is that? what can CPUs do when it comes to raytraceing atm?

Its not about mobile, it sounds like its for high-end users, that want to do raytraceing.
Maybe even mainstream gameing (on a pc), with raytraceing.

From the article it looks like professional workstation use is the first goal, then a move to high end desktops. I think it'll be a while before RT becomes standard on home computers. The 'ol way of doing things still has a lot of life left in it, especially when considering performance.

so what uses Ray Tracing in the consumer space? is this aimed at enterprise rendering? movie industry etc?

So, which is more efficient - Ray tracing, or rasterisation/rasterising/whatever?

The thing about RayTraceing is that its photo realistic.
You can have a beam of light mimic real light. How light bends going through glass/water ect, reflections ect ect.

You need insane amounts of compute power to do it (currently its very in-efficient/demanding).

Im not saying its prettier, because that depends on whats done with each tech.

Currently however it takes something like 4 x Intel Westmere EX processors
(10 cores, 20 threads each = 80 cpu threads). To mimic light in a semi-real time photoshop pic of a chess-board in 3D.
So 80 CPU threads, to be able to "turn" a flat still picture of a chess board.

Ray traceing isnt "viable" currently, for the things we do with 3D games.
Itd be so "demanding" on the system, you would have to settle for "less" or "worse" than we currently have from 3D games.

Whats needed is a breakthrough in ray-traceing, or for super computers to become a common house hold item. Before that happends, Ray traceing for 3D gameing is a pipe dream.

I have to wonder if this is some kind of stock scam to lure gullible investors based on magic new technology. Intel was taking the ray tracing approach with Larrabee and failed miserably.
