For the purpose of HTPC reviews (in particular, HQV benchmarking for discrete GPUs), we have set up a dedicated testbed with the following configuration.

HTPC Benchmarking Testbed Setup
Processor Intel i5-680 CPU - 3.60GHz, 4MB Cache
Motherboard ASUS P7H55D-M EVO
OS Hard Drive Seagate Barracuda XT 2 TB
Secondary Drive Kingston SSDNow 128GB
Memory G.SKILL ECO Series 4GB (2 x 2GB) SDRAM DDR3 1333 (PC3 10666) F3-10666CL7D-4GBECO CAS 7-7-7-21
Video Cards Various
Optical Drives ASUS 8X Blu-ray Drive Model BC-08B1ST
Case Antec VERIS Fusion Remote Max
Power Supply Antec TruePower New TP-550 550W
Operating System Windows 7 Ultimate x64
.

This is the same configuration that we had for evaluating the GT 430 last fall. Windows 7 was updated to SP1, but that has little bearing on our HTPC benchmarks.

Each hardware configuration has an associated OS image which was created / restored as necessary using Clonezilla. This ensures that we do not end up with conflicting drivers while evaluating GPUs from different companies on the same base testbed. Read on for the results from benchmarking the four candidates with the HQV clips

    A great review. Provides all the answers one could wish for and even gives some further hints.
    I sure hope you have something like this lined up for llano.

    If I may suggest a couple or three things:
    Perhaps you should also mention reclock - it will solve most 23.976 and similar problems... It's not like many will detect that the video is running 1/24000th faster. Plus it's insanely easy to use.
    I understand you couldn't just post full blown images for space problems, but those thumbnails require too much work too. Is it possible to display a popup of sorts when one mouse-overs those thumbnails?
    Also a vertical line showing 60FPS in those DXVA tests would be great :)

    I will pass on your request(s) to the person in charge of the graphing engine :) Reply

    What might have been a nice option is to see what sound levels the cards produced. Even it was only for the GT430 and the HD6570. I know that the decibels can differ between manufacturers but it would have been nice!
    For the rest a very nice detailed review between HTPC cards. I was deciding which card to buy so this helped a great deal! I was only looking between the HD6450 and the HD6570 but the GT430 is a better option than the HD6450.

    HDMI Audio is purely digital, there is no diference based on what card you use.

    It depends on the audio decoder, and your receiver at the other end of the HDMI link, the HDMI sound card on those cards does not change the audio.

    I think I did not use the right word, as I meant the levels of decibel the fan of the cards produce and not the audio too and through speakers.
    All reviewed cards have a fan on them and since most of the HTPC setups are in the living room it would have been nice to know which of the cards are most silent.

    Though we considered cards with fans in this review, we made it a point to note that the same configuration (GPU model + DRAM bus width + operating frequencies) can be obtained with passive cooling from other vendors.

    For example, the 6570 has a passively cooled model from HIS with the same config and Zotac has a passively cooled 430 too. Other vendors have also demonstrated passively cooled models in Computex.

    Firstly, a truly informative article. Very high quality.

    The fact that none of AMD, Intel and Nvidia can lock onto to the correct frame rates is unforgiveable. It is not as though these frame rates have changed over the last 6 months. It should not be necessary to be an advanced HTPC user and delve into custom creation of frame rates.

    I really hope that the representatives of AMD, Intel and NVidia are hanging their heads in shame at such basic errors - sadly I doubt they care.

    The mistake is rather with Microsoft. Video playback speed should be adapted to the refresh rate of the grafx card. There is a software called Reclock doing that. Then, for example 23,996 Hz can be run with a monitor refresh rate of n times 24 Hz. (The same with audio, because bit-perfect transmission only works with synchronization.) In the end and for most sources, the RAMDAC needed only (multiples of) 24, 25 and 30 Hz. In any system, one of its parts should be the clock master, while the other parts serve. Reply

    Excellent review, Ganesh! Your HTPC insight/reviews have been missed. Reply
