Part 4: Avivo HD vs. PureVideo HD

Resolution Benchmarks: 1080p vs. 780p

First off, since we noticed smoother playback on the GeForce 8200 at lower resolutions, let’s examine the CPU utilization difference between 720p (1280x720) and 1080p (1920x1080):

Now we’re getting somewhere. While overall CPU utilization didn’t drop that much, note that the CPU utilization is much more consistent at the lower 720p resolution. As a result, we’re not seeing the dropped frames and skipping performance.

Let’s compare this to what happens to the Radeon 3200 when we lower the resolution:

There doesn’t appear to be any CPU spiking at the higher resolution with the Radeon 3200. As the resolution is dropped, CPU utilization lowered a bit. But playback appeared skip-free at either resolution.

Based on CPU utilization, it looks like the GeForce 8200 can decode the demanding H.264 content just fine, but it seems that as the resolution is raised past 720p there’s a bottleneck happening somewhere else and playback suffers.

Frankly, this is a serious blow to the integrated GeForce 8200’s potential as a home theater PC platform. While it’s true that it was able to play back two of the three titles we tested at the 1080p resolution, it’s a pretty serious limitation that resolution potentially has to be lowered to 720p for demanding titles, especially since the Radeon 3200 displays no such limitation.

With this in mind, we are curious as to how these platforms will perform with CPUs that are slower than the 4800+. Are either of these system viable HTPC platforms with cheaper, single-core processors?

    Don't the 780G chips have hybrid technology? It would have been great to see what kind of performance difference it would make to add a discrete card with a 780G chip. Motherboards with integrated graphics cost about the same as those without integrated graphics, and so I would choose an integrated graphics + a discrete graphic card for hybrid performance.

    Wao, you should update this article part 5 in tuesday when NDA 9300 lift out. 9300 vs 790GX. Does this NVidia VGA also defect?

    Nice job Don !
    Interesting seeing the theoretical HQV difference being a realistic nil due to playability (does image enhancement of a skipping image matter?)

    I'll be linking to this one again.

    Next round HD4K vs GTX vs GF9 integrated, complete with dual view decoding. >B~)

    Great article, specially liked the decrypted video benchmarks as I was indeed expecting a much higher difference.

    Also was expecting that the single core handled it better as I use a old laptop with pentium M 1500mhz & ATI 9600 as a HTPC and it plays nearly all HD media I trow at it smoothly (Including 1080P) trough ffdshow. Notice the files are usually Matroska or AVI and the codecs vary but usually are H264.

    I admit since its an old PC without blueray or HD-DVD I have no idea how the "real deal" would perform, probably as bad or worse as the article says :P

    I have a gigabyte GA-MA78GM-S2H m/b (780G)
    I just bought a Samsung LE46A656 TV and I have the following problem:

    When I connect the TV with standard VGA (D-SUB) cable,
    I can use Full HD (1920 X 1080) correctly.

    If I use the HDMI or DVI (with DVI-> HDMI adaptor) I can not use 1920 X 1080 correctly.
    The screen has black borders on all sides (about 3cm) and the picture is weird, like the monitor was not driven in its native resolution, but the 1920 X 1080 signal was compressed to the resolution that was visible on my TV.

    I also tried my old laptop (also ATI, x700) and had the same problem.
    I thought that my TV was defective but then I tried an old NVIDIA card I had and everything worked perfect!!!
    Full 1920 X 1080 with my HDMI input (with DVI-> HDMI adaptor).

    I don't know if this is a ATI driver problem or a general ATI hardware limitation,
    but I WILL NEVER BUY ATI AGAIN.
    They claim HDMI with full HD support. Well they are lying!

    That's funny, bit-tech had some rather different numbers for HQV tests for the 780g board.

    http://www.bit-tech.net/hardware/2008/03/04/amd_780g_integrated_graphics_chipset/10

    What's going on here? I assume bit-tech tweaked player settings to improve results, and you guys left everything at default?

    What about the image enhacements in the HQV test posible with a 780G and a Phenom procesor?, would this mix stand up in front of the discrete solution chosen?.
    This one could be an interesting part V in the articles series.

    Guys...I own this Gigabyte board. HDCP works over DVI because that's what I use at home. Albeit I go from DVI from the motherboard to HDMI on the TV (don't ask why, it's just the cable I had). I don't have ANYDVD so, I know that it works.

    As for the guy having issues with HDMI with the ATI 3200 onboard, dude, there were some problems with the initial BIOS. Update them, update your drivers and you won't have a problem. My brother has the same board too and he uses HDMI and it works just fine. Noob...

    Yes I own GeForce 8300 IGP... I can confirm it does frame skips in just normal high quality DVD, i hate it... watching some stops... I test using ATI HD2600 external, wow it moves flawlessly and more vibrant, I regret my mobo, I should have bought ATI

    Why did not test the 780g and 790gx boards with side port ram?

    HQV is, unfortunately, somewhat subjective - but I don't know how they could have gotten these scores. Ati told me directly that their low-end cards won't provide any HD enhancements. That was some time ago, and bit-tech aren't a bunch of incompetents, so it's hard to say exactly what's causing the diffrence here.

    I don't believe the quality will change with faster processors - I tested a Phenom 9500 and didn't see any diffrence. But I'll run a proper test and let you know.

    "In this author’s opinion, motherboard manufacturers would much better serve their customers by offering an HDCP enabled DVI output with a DVI-to-HDMI adapter, instead of HDMI outputs."

    Wow. You seem to be REALLY missing the point here. The whole point of this is for HTCPs, and the nice thing about HDMI is that it can send both video and audio to your tv over the cable. If they had a DVI port on the motherboard and you had to use an HDMI adapter, you would have no sound. Doing it the other way around though ensures that people who use it for an HTCP like it is intended get their sound, and those who want to use a monitor buy a DVI adapter. You didn't even seem to mention or test the capabilities of sending audio over HDMI!

    I don't complain about my laptop not having a DVI out, and when I want to hook it up to my friends 32" HDTV all I have to do is plug in a simple HDMI cable. If I wanted to run and LCD at home I'd buy an adapter.

    I have found that even slow CPUs can playback H.264 AVI files; something's going on when playing back a blu-ray, probably the encryption. I was hoping the AnyDVD HD benchmarks would expose this but that's not what we saw. I'll be digging into it further in a future review for sure.

    That is really bizarre... are you sure it works? Have you played back protected Blu-ray or HD DVD's over the DVI cable?

    During my testing it didn't work at all, and then when I checked around I was led to understand HDCP wasn't supported on the DVI out of that board.

    Well, I'll disagree with you that these boards will ONLY be used for HTPCs, as I've stated I believe that these value-priced boards would be attractive to a whole lot of people with decent monitors who would like HD playback.

    As for sound, you can certainly play it back over the integrated sound chip instead of HDMI, so I don't think "you would have no sound." is an accurate discription.

    CnQ on? Why not test 8450e as well? 8200 doesn't work well with Athlon 64 X2, but it seems to work better with Phenom. I don't have blu-ray so I can't confirm how it perform with Phenoms.
