These drivers open up a can of joy for sure. Yesterday NVIDIA provided us with internal Beta test-drivers. The 2400 XT is good, yet IQ wise is significantly less than that Radeon 2600 series. Meanwhile, ATI's Radeon HD 2600 XT almost scored a perfect 100% on everything HD related. On the other side, huge props to ATI-AMD though as from day one of the release they had this working perfectly. It's all about driver development which for months now has been NVIDIA's biggest Achilles heel.
I'm absolutely certain that NVIDIA will get this ball rolling though as we noticed exactly the same with the original HQV tests (DVD). The poor HQV-HD results however did raise my eyebrows as that was definitely a disappointment. See they added new dedicated core logic (VP2) in their video processors, exactly for this stuff. We hardly spot noise reduction, and the film-tests where simply disappointing from a quality perspective, moiré effects everything was just not looking good.īut I assure you over time NVIDIA's drivers will enable a better score and this yield a better result, and VC-1 although not fully accelerated really isn't a big issue as rumors claim. ATI kicked butt NVIDIA's results however disappointed big-time. With the current drivers it's not post-processing the content as the way it's meant to be played back. Now it's save to say that both mid-range competitors have excellent VPU's (video processing unit) in their new mid-range products. Amazing stuff, both AMD-ATI and NVIDIA have done a great job here. Truly amazing, as when you disable GPU acceleration our CPU (C2D 6800- 2.9 GHz Dual Core) would show an average of 40% CPU utilization with peaks towards 50%.
At certain intervals during the decoding stage we noticed a CPU load stage of 0% while it was decoding and displaying Pan's Labyrinth at 1920x1080i at a dope 20-25 Mbit/sec bitstream. there's no way I can describe you how well both 2400, 26 cards can cope with it. When we take a deeper look at h.264 decoding then literally. ATI is definitely the winner in this segment. When we peek at VC-1 decoding there's definitely some gain with NVIDIA's PureVideo HD compatible products yet the Radeon Avivo HD in combo with a HD 2600 XT card was showing extremely impressive results. A PC with a Core 2 Duo E6600 for example would achieve a CPU load of roughly 30-40% during that decoding process. Even if you wouldn't use the graphics card as accelerator. Apparently our test-system in combo with PowerDVD does not have a problem accelerating HD content at all. It's impressive to see what today's cards are capable of when decoding, accelerating and enhancing HD content.
