[Tilt, TyTN II, MDA Vario III General] undac:
haven't seen much about the specifics before so I dug up some facts:

It's most likely an Imageon 23xx based co-processor. None of the Imageon products that are on ATi/AMDs site match Qualcomms specs though.

The closest one I can find is the Imageon 238X.

Qualcomms says in their PDF that: "The MSM 3D feature set improves performance even higher than published specifications while reducing power usage"

From what I think I'd say it's a Imageon 2380 or 2388 product that they have clocked higher than the official specs. (Just a hunch)

here are some quotes about the minimum baseline of what we can expect:

"[...]the Imageon processors provide features such as 3D gaming, Video/Image capture (MMS), and MPEG 4 playback."

and

"[...]JPEG encoding/decoding[...]"

ie it's confirmed that his could indeed also speed up the camera functionality: both stills and video.

It doesn't seem to have a native Direct3D Mobile driver. So instead we would probably need a wrapper (and an Open GL ES driver) as seen in the LG KS20.

"With support for ultra low-power SDRAM"

This memory is actually on-chip.

It also supports up to 16 megabytes of external, but yet dedicated, low power SDRAM. (We have no idea how much, if any such memory there is)

It's confirmed that there is some dedicated VRAM but we have no way of talling how much or if it's on-chip or external. In any case it means that we would get some more free memory (even in regular apps) as the framebuffer would be stored in VRAM instead of regular RAM if we had the proper drivers.

It also has a mandatory 384 KB SRAM (ie enough for 320x240 @ 16 bpp in 2D at least)

"The highly optimized Imageon™ architecture enable low cost, low power system designs by lowering CPU utilization thereby extending battery life thus eliminating the need for high powered CPU's and/or larger batteries."

and

"[...]and minimize overall power consumption resulting in longer battery life. [...]"

and

"Enhanced PowerPlay™ power management technology for longer battery life"

As expected enabling hardware acceleration decreases energy consumption (instead of increasing it like the good folks of pocketnow.com tried to imply)

And from Qualcomms specs this is what we can expect:

It supports hardware acceleration of:

DirectDraw, JSR184, GDI, Open GL ES Common 1.0 and a select few instructions of 1.1, BREW Render2D, uiOne 3D and Direct3D Mobile Shader Model 2 (though most probably through a wrapper only but from what i've read it's efficient and almost transparent)

To put it in perspective Open GL ES 2.0 is the latest GL spec and Direct3D Mobile Shader Model 3 is the latest D3D spec.

It's a fixed function 3D pipeline (ie not programmable). Roughly comparable to DirectX7 for the desktop platforms.

(The document also has some sweet info on Qualcomms upcoming 1 Ghz chipset.

It supports DX9 and some DX10 functionality (Direct3D Mobile Shader Model 3). Open GL ES 2.1 etc.)
