NV34 DX9 compliant?

Courtesy of Beyond3D vis way of nVidia's quarterly conference call (which doesnt seem to have made it's way on the net as yet)

Nothing terribly new besides this one point which seems to add credence to the idea that the low end NV34 will be fully DX9 compliant contrary to Digit-Life recent claims. The mere code name of NV 3X would certainly seem to imply that it's dirivative of the DX9 compliant GeForce FX.
Then again, the ocde name may not necessarily mean much... afterall the NV31 is supposedly a higher performance part then the NV31 despite the lower naming.


Of note is that they are currently ramping up three new products at TSMC, one of which is most likely to be NV30 (GeForce FX 5800) and its likely that the other two are the NV31 and NV34 range said to be announced at CeBit. The GeForce FX range will be brought all the way down from the high end $300-$400 top end to the $99 entry point. This low end point is assumed to be filled by the NV34 product and the mainstream parts will be filled by NV31 based products. However, given that this is described as GeForce FX, and DX9 parts were referenced to a number of times in the conference call, this would appear to be some level confirmation from NVIDIA?s management that they are moving away from the GeForce 4 Ti/MX differences to a single DirectX9 platform from top to bottom.

That the NV31 will be fully DX9 compliant is fully expected of course, as they'll need something to compete in the midrange against ATi's R9500 series which has been on the market for awhile now.

I sincerely hope that the NV34 will be DX9 as well though.... it's disturbing that DX8 still isnt even the lowest common denominator on the low end as yet, let alone DX9. All of their competitors have PS/VS shader capable boards whereas nVidia is left resting on the laurels of the tired GF4 MX line.

Skipping DX8 entirely and jumping directly to DX9 would be quite interesting indeed, it would be a huge boon to the software market in creating a larger installed base of DX9 boards. At a minimum it should propel usage of light PS into the common game.

It may also serve to help push ATi into releasing the RV350 earlier then expected, The RV350 is likely all but finished, just as the RV250 and RV200 cores were finished months before actual release.

It would seem reasonable that they would leave out hardware VS and allow the CPU to handle that, as for now the processor is still quite capable of effectively emulating VS quite well.
The Xabre route of hardware PS, and software VS would seem to make considerable sense on the low end as a means of reducing cost while still maintaining base DX 8/9 compliancy.

<pure speculation>

if NV31 and NV34 aren't DX9 parts, they would sure look bad in 3dMark03... probably worse than the 9500/9000 parts that they are supposed to compete with ;)

Hmmm... I'd surely want to discredit the valididy of 3dMark03 if I knew my mainstream parts were going to perform poorly on the 3Dmark bench vs ATI...

</pure speculation>

It would be on reason too dscredit 3DM2003, but I suspect they would do so in any case simply because all of their present graphics cards are easily beaten out by the R9500 non-pro.
It doesnt look good to have the 'high end' GF4 Ti 4600 beaten out by the 'lower midrange' R9500, and have "No Supported" come up whereas the 9500 is quite capable of rendering the tests.

I wonder if their going to continue recommending 3DM2001 as a measurement of how beneficial a graphics card upgrade is as they presently do.
