Blu-ray Playback Quality and Performance

We expected Intel's G45 to be the holy grail of HTPC chipsets; unfortunately, driver limitations kept it from fulfilling that role. While the verdict is still out on what G45 may become, Intel's track record with taking care of the HTPC space with its chipsets hasn't been great, as Intel's own blogger will readily admit. (Who, by the way, is an excellent addition to Intel. While the message he carries may not be the most popular within Intel, his understanding of the market is top notch - promote this guy!)

Thus we turn to NVIDIA's GeForce 9300 for hope. Prior to today, your best bet for a solid HTPC solution was to buy an Intel G45 or P45 based motherboard and stick a Radeon HD 4550 in a vacant PCIe slot for proper HDMI, HDCP and 8-channel LPCM support without any issues. Does NVIDIA's GeForce 9300 change that?

An astounding yes.

The Blu-ray decode quality of the GeForce 9300 is identical to the GeForce 8200, which in turn is identical to the G45 and AMD's 780G - as you'd expect. The comparison below is the one we used from Part 2 of the IGP Chronicles:


AMD 780G

We've also got full hardware decode for MPEG-2, VC-1 and H.264 on the GPU itself, which results in very low CPU utilization numbers while playing back Blu-ray and other supported HD content:

VC-1 Blu-ray Playback: Dave Matthews Concert BD

MPEG-2 Blu-ray Playback: Crank BD

H.264 Blu-ray Playback: Simpsons BD

H.264 Blu-ray Playback: Simpsons BD

The Motherboards: Available Today Blu-ray Power Consumption

    I switched from a Pioneer Elite to Integra DHC-9.9 and to me it seems like the Pioneer sounds better. Pioneer during its speaker setup also setup EQ to compensate for room modes. I did not see Integra do that.

    I wish you said atleast one sentence on why you would go from Pioneer to DTC 9.8.
    Better sound?

    I have never fully understood "PureVideo". It is my understanding that this is only supported by a handful few players, like the awfully buggy PowerDVD that simply won't run on my system (PowerDVD no longer support SCSI DVD-ROM).

    Funny, Windows Media Player and PureVideo works fine for me?

    The performance for Ethernet CPU usage seems rather poor. In fact all of them are bad, as Intel should be in the region of single digit percentage shown in other website.

    One interesting point i realize while reading, i hope to share with their reader.
    Is that measuring the few percentage difference with low CPU resoource usage playing H.264 Full HD isn't very important at all... Why?

    Because the difference between 15 - 25% , while 10% looks like a lot, the most important factor is POWER CONSUMPTION. While most people would think lower CPU usage and therefore lower power usage. In this article it turns out while Geforce has the lowest power consumption while using most CPU resources.

    And how many people use their CPU for other heavy task while watching Full HD Movie?

    I cant wait to see these being refreshed next summer, with 40nm, more die space because memory and most northbridge move to CPU, we should be able to put more then double the shader inside?

    I know the focus is on Blu-ray and progressive source material, but most people stil have SD DVDs and 1080i TV broadcasts that they want to play back on their HTPC.

    Adequate deinterlacing, detail enhancement and noise reduction have been the missing pieces of the puzzle for all other IGPs except the 780G + Phenom combination, but that has other issues.

    What about the 9300/9400? Does the increased GPU power allow for better processing?

    If it doesn't, there is one other check missing on your list, in my opinion.

    So is this the article that was supposed to come out analyzing the 780G, 8200, and G45? You know, months.... and months.... and months ago? I'm glad you guys waited until nVidia released a competative product before releasing this article. Otherwise I would have bought a 780G motherboard months ago.

    I wish you guys wouldn't use the Sony BDU-X10S in your testing. I've owned this drive and it just sucks. Had problems on both Intel and NVIDIA chipsets.

    As for the data transferring problem, I had the same problem recently on my Badaxe2 motherboard. I was moving my hard drive from my Geforce 8200 system to Intel G45 system but first needed to copy recordings to another hard drive so that I could format the hard drive. My desktop has a Badaxe2 is running Vista x64 and I too randomly experienced pauses when copying 500GB of data. Not sure if it is related but it might just be a Vista thing.

    Hi Anand/Gary,

    In your next installment, can you please find the slowest usable CPU that plays Bluray smoothly and also test Speedstep with it? Using a quadcore is really overkill and kind of defeats the purpose of GPU DXVA. The 8200 w/ a 4850e cannot utilize CnQ to playback BR. I'd like to see whether a 9300 w/ E5200 or E7200 and Speedstep enabled can play BR smoothly.

    Thanks.

    Nice LL Cool J reference in the article description!
