Test Setup

Since we have so many cards here to test, we wanted to keep things fairly simple, rather than have a large number of games and resolutions in our performance graphs. We chose two games which offer a good example of the current generation of gaming and tested the cards with benchmarks from each of them. The games we chose are Battlefield 2 and The Elder Scrolls IV: Oblivion. We chose to run our gaming benchmarks at 1280x1024 and 1600x1200 resolutions. We also kept AA and AF off, and sound was disabled. Here is the testbed we used for our performance tests:

Performance Test Configuration
CPU: Intel Core 2 Duo E6300 (1.86GHz/2MB)
Motherboard(s): Intel D975XBX (LGA-775)
Chipset(s): Intel 975X
Chipset Drivers: Intel 7.2.2.1007 (Intel)
Hard Disk: Seagate 7200.7 160GB SATA
Memory: Corsair XMS2 DDR2-800 4-4-4-12 (1GB x 2)
Video Cards: Various
Video Drivers: ATI Catalyst 6.10
NVIDIA ForceWare 91.47
Desktop Resolution: 1600 x 1200 - 32-bit @ 60Hz
OS: Windows XP Professional SP2

    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.] Reply

    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. Reply
