NVIDIA and ATI HDCP Compatible Graphics Cards Roundup

EVGA e-GeForce 7900 GS KO
The first card we have from EVGA is the e-GeForce 7900 GS KO. EVGA has always impressed us with its product quality and customer support, as well as its warranty policy.
EVGA e-GeForce 7950 GT KO
Secondly, we have the EVGA 7950 GT KO. Like the EVGA 7900 GS KO, the card looks very similar to the reference 7950 GT except with a few additions by EVGA to the heat sink.
The EVGA 7950 GT KO comes with a factory overclock of 560MHz on the core and 725MHz on the memory clocks. This isn't quite as much as the super clocked version of this card (which comes with a core clock of 600MHz), but it will help performance nonetheless. Like other 7950 GTs, this card comes with two standard DVI outputs as well as component out, and it requires a 6-pin PCIe power connector.
EVGA e-GeForce 7950 GX2
The last EVGA card we have is the 7950 GX2. These cards were formerly the highest performance "single slot" cards from NVIDIA, as our performance graphs will show later in the review. Of course, the 8800 GTX has now displaced the GX2 as king of the hill.
The EVGA e-GeForce 7950 GX2 looks very much like a reference 7950 GX2, except with EVGA's trademark black logo design on the heatsink. The e-GeForce 7950 GX2 came to us clocked at reference speeds, with 500MHz on the core and 600MHz on the memory clock. The EVGA e-GeForce 7950 GX2 has the same outputs as the 7950 GT; dual DVI ports and one analog video output.

I personally think this article was extremely on point with the direction of media components in general. I think there will be many people out there, like me, who are planning on the convergence of the Media Center PC & Gaming PC. Vista (Ultimate) will bring Media Center to the masses and why shouldn't you be able to play your favorite DX10 "Game for Windows" on your big HDTV as well?
This article is ahead of its time. HDPC/DRM/HDMI/DVI/BR/HD-DVD/HDTV is all in the early stages. In the future, you will be able to buy or rent your high-def movie by downloading it to your PC with DRM finally figured out. This review shows us that it is not all there yet, but gives us an idea who is doing what, and what we need to look for.
You mentioned in the beginning of the article that you were looking for feedback to see how interested your audience is on this subject... count me as 1.

HDCP is a joke... look at how hard it is to understand and get this stuff running... not to mention you have upgrade all your hardware?? lol and who watches movies on their PC anyway?? do you people really sit huddled over your keyboard watching movies?? Why not invest in some better equipment for the family room and watch movies they way they were intended....but the difficulty in setting all this up makes it even more important that hdcp has already been cracked... i wouldnt let the movie industry tell you your hardware isnt good enough to buy their content... just buy what you want and "work" around the issue later... the cracks are only getting better.... we'll see HD-DVD Shrink soon enough...

Careful - it's not safe to assume that higher bitrate content is more computationally difficult to decode than lower bitrate content. [In fact, I suspect they're weakly correlated the other way - lower bitrate is harder.]DerekWilson - Monday, November 20, 2006 - link
ahh ... very interesting ...it would make sense to me to say that both are true.
In the case where low bitrate means more aggressive high quality encoding, i absolutely see your point. But low bitrate can also mean lower quality (less information) at the same level of encoding -- in these cases lower bitrate will be easier to decode.
Thanks for pointing this out.

Hi Derek,Can you comment on HD audio formats like Dolby TrueHD and DTS-HD for the HTPC? I know Bluray has yet to use these formats but how about HD-DVD on the HTPC. From what I understand, you could get these formats outputted via analog output on your soundcard, but I'm interested in HDMI. I know some of the HDMI video cards you reviewed have SPDIF passthrough via HDMI, however SPDIF cannot carry Dolby Digital +, TrueHD, or DTS-HD, it will only output DTS or DD. I'm holding back on a HDCP video card because HD audio is an important part of HD movies.
Thanks.

p.13 "Both the 8800 GTX and GTS are fully HDCP compatible, and HDCP is enabled through both DVI ports" p.22 "Some of the cards, like the HDMI Gigabyte 7600 GS and ASUS EN7600 GT, were only able to play our Blu-ray movies over HDMI and not through the DVI port. Conversely, we found that with our MSI NX7600 GT Diamond Plus, the Blu-ray content wouldn't play through the HDMI connection but it would through the DVI port."OK, so which cards (other than the 8800s) could do HDCP over both ports?
----
p.19 "The end result is that an NVIDIA card with more pipelines that is better at 3D performance will not necessarily be better at video decoding."
In other words overclocking (say) a 7600 is likely to give as good or better HD video results than using (say) a 7950GX2?
----
p.20 "In the future, we could see power consumption go down with acceleration enabled. As graphics hardware is better suited to processing video than a CPU, efficiency should go up when using hardware acceleration."
The results for the 9750GTs already seem to show this 147W average non-accelerated >> 142 for EVGA & PNY (although Gigabyte > 148W).

...can we get it added to these results just for comparison?Also, you don't happen to know when that'd be, would you? :)

I noticed that in the cpu utilisation tests you said it was around 51% for no acceleration - was this because the player software is single threaded and so only used one core?Also, is click encoded in h264, or mpeg2 like the initial bluray discs?

Now that the Xbox 360 HD-DVD drive is available and is proven to work with a PC, any chance on doing another round-up "real soon now" using HD-DVD? I'd really love to see the numbers for VC1 and H.264 decoding.Still amazed that the lowly X1600 card spanked all Nvidia cards but the G80 boards in CPU utilization.
Good job guys.

BTW, the new releases from Fox on Blu-Ray use the H.264 codec. Behind Enemy Lines, Fantastic 4, etc. I think Behind... is already out.
