Programmable Encoding Anyone?


That's right, NV4x includes a dedicated programmable video processor. The video processor is made up of an address, scalar, vector, and branch unit. The vector unit is a 16 way SIMD (a single instruction can operate on 16 different pieces of data at once) vector unit.

We don't have anything to test this thing with right now, but there is a whole lot this thing can do, including inverse 3:2 pulldown (conversion from interlaced TV format to progressive format better suited to computer monitors), colorspace conversion, gamma correction, MPEG 2 MPEG 4 WMV9 DiVX decoding and encoding, scaling, frame rate conversion, and anything else you'd like it to do for you.

This a very exciting feature to be included on the GPU. It essentially means that anyone with an NV4x chip including the video processor will be able to stream video all over the place, do very fast encoding, and offload a lot of work from the processor when it comes to video processing. Also, it could really help in multimedia and PVR style systems by lowering the necessary CPU power to something more affordable (that is, as long as this functionality is included across the board on NV4x chips).

This could actually really help even the playing field between Intel and AMD if it catches on ...

    I'd like to see benchmarks of Painkiller in the upcoming NV40 vs R420 tests...

    Am I the only one who thinks Nvidia's Nalu is the MOST bone-able cartoon out there?

    Oy, get the KY!

    Did any reviews try and overclock the card? Is it not possible with the test card?

    Would have been better if it had a coax cable TV input + TV tuner. For $500, I would expect a graphic card to include EVERYTHING imaginable.

    Shinei #37,

    "Speaking of DX9/PS2.0, what about a Max Payne 2 benchmark?"

    MP2 doesn't use DX9 effects. The game requires DX9 compatability, but only DX8 compliance for full effects.

    Xbit-Labs has a ton of benches of next-gen titles as well, and is worth checking out. NV40 certainly redeems itself in the HL2 leak. :)

    Anybody happen to know if it's possible to use a second (old) PSU to run it, you can pick up cheap 235 watt PSU's and would be helped with both extra connectors and power.
    I'm not sure it won't cause 'sync' problems though as a small difference between the rails of 2 PSU's would cause one to drain the other if the card's connectors aren't decoupled enough from the AGP port.

    Agrre with you Trog #59 on the venting. Also with DX9.0c having fp32 as spec., does this mean that FX series cards redeem themselves? (As the earlier DX9 spec was fp24 which was'nt present on the FX gpus causing a juggling act between fp16 and fp32 to match performance and IQ). Still, full fp32 on the FX cards might be too slow.

    What's with all the cheesy comments before the benchmarks? Anyone?

    "what mobo and mobo drivers were used? i hear that the nforce2 provides an unfair performance advantage for nvidia"

    The test was on an Athlon 64 3400+ system, so i doubt it was using an Nforce2. But ya, i agree, the system specs were short. More details are required.

    Derek, what was that Monitor you used?

    Thanks!
