HARDSPELL - DX10 is universalizing: G86/G84 complete test! (April 18, 2007)

I found it's very hard to access this site. So I will post the CPU usage charts in page 16 to 26. (Downloading one picture took more than 500 attempts for an hour using FreeDownloader!)
  • Test Setup

    • CPU:
      • AMD Athlon 64 X2 3800+ (dual-core) 2.0GHz
      • Sempron 2800+ (single-core) 1.6GHz
    • Motherboard: ASUS M2N32-SLI Premium (Socket AM2)
    • OS: Windows Vista
    • VGA card:
      • GeForce 8600GTS 675/2000MHz
      • GeForce 8600GT 540/1400MHz

      • GeForce 8800GTX 575/1800MHz
      • GeForce 7900GS 450/1400MHz
      • GeForce 7600GT 560/1400MHz

Wow!

Look at the 8800 gtx.

Can we assume similar results with XP this test setup in Vista? Or:

"Pure Video HD acceleration for the GeForce 8600 GTS and GT is ONLY available for Windows Vista"

is that the same thing as h264 acceleration?

Almost surely yes once the XP driver is released in June. The video engine of Geforce 8800 series is the same as Geforce 7 Series. In particular 8800 lacks the H.264 bitstream processor and there is no way for it to compete with 8600/8500 in H.264 decode.

The new Video Processor (VP2) integrates the inverse transform process in HD (MPEG-2, VC-1, H.264) decode and the AES-128 decryption engine was added. However from the viewpoint of offload from the CPU, the second generation PureVideo HD engine is almost a synonym for the new H.264 bitstream process engine. That is the reason why there is no big difference in VC-1 decode between 8600/8500 and 8800/7x00.

Those numbers are really encouraging... but as someone mentioned earlier I am waiting to hear how the video quality holds up. I think anand stated in their initial review of the 8 series cards that they are going to be running their hqv benchmarks later.

Which is good although hqv places too much emphasis on bad edit handling and not enough on black level, contrast ratio, detail and color accuracy.

There are several 8500 cards that support HDCP. Here is one:
GIGABYTE GV-NX85T256H GeForce 8500GT

I think I'm going to pick this one up!

well i pulled the trigger and ordered up a gigabyte 8600gts for my new htpc (also got a core 2 duo 6600). should have everything hooked up and running by next weekend.

OK, since i couldn't wait for the fanless version of the 8600 gts (which by the way appears to be underclocked), i'm now wondering about aftermarket cooling in case the stock cooling system is to loud. I wonder if anyone has gleaned any info about this. would the thermalright 8800 cooler work?

Anyone know how well the passive cooling works on the Gigabyte? Does its performance match its fan brother? How about overclocked?

XFX GF 8600GT PV-T84J-UDD3 HDCP Capable **
** Requires other compatible components that are also HDCP capable

Driver 158.18 vista 32 bit

HDCP not ok :

7950GT is ok in this PC.

Has someone this card or another 8600 with HDCP working ok ?

"The XFX 8600 GT XXX won't really be able to take advantage of the PureVideo HD benefits though since it does not support HDCP."

http://www.legitreviews.com/article/486/3/

"XFX did not enable HDCP and HDMI support, which is optional on the GeForce 8600GT."

http://www.realworldbenchmarks.com/a...3&pagenumber=2

"The rear of the XFX 8600 GT XXX Edition shows the key features. Our review sample package does have an error on it that we should address. The 8600 GT has the option to support HDCP playback and the box currently states that the card is HDCP Capable. This is actually an error that XFX plans to have fixed for the retail and e-tail launch later today."

If this is true, you'd better return it.

I'm also considering the AMD/ATI R600 coming out this month. Apparently it will have the audio on the HDMI output. But I have no idea on the pricing that will be offered.

You can find the update on cyberlink website
PowerDVDUltra.2605n_DVD070306-02.exe

some complete tests are available on an asiatic website just search with google "windvd 8.0.8 8600"


So does this mean I need to UPDATE PowerDVD Version 7.3 in order to take advantage of my new 8500 GT (In Transit) features?


Any info regarding Update Benefits / Requirements would be Very Much Appreciated.

Hello,

I made the update before testing, but I think that the update is required,

Yeah, me too. Looking at the layout of the 8500/8600 it probably should be the same as the 8800, but you never know what bugs NVidia felt compelled to add.

HAving just received my 8500GT (Gigabyte passive HDCP) I can say there is a definate improvement in video quality. The color depth is definately superior to the 7xxx part I was using before.

I also saw a drop in VC-1 CPU by roughly 20%, I am not seeing any change in x.264 but that's probably a problem on my end I would imagine. Any thoughts here? I am using FFDshow for h.264 playback, so I am assuming I won't get any hardware acceleration there, or?

Are you running xp or vista? supposedly xp support for the h.264 acceleration won't be out until june...

Doesn't look like they tested the hd capabilities at all. The review is almost entirely game-based, which doesn't really help for those of us just interested in the card from an htpc point of view.

It does say at the beginning that "A deeper look at the G84's video processing capabilities will also follow", so hopefully there should be something soon.

From a gaming point of view however the results are rather disappointing.

The test results @ the top of this page used PowerDVD that may boost your H.264 acceleration?

I have an 8600 GTS on XP SP2. The DirectX capabilities on XP only claim MPEG-2 support. But this is done in the drivers. The CPU utilisation is insanely high for MPEG-2 decoding. SD MPEG-2 takes as much CPU as HD MPEG-2 used to take with the 7600 GT. The deinterlacing is better, but I don't think it's done on the card. Most of the CPU utilisation is in the kernel so the drivers are doing the decoding but 'tis not being done on the card.

For example 1080i HD MPEG-2 on my machine (Sempron 3400 (2.0 GHz), XP SP2, 1.5 GB DDR400) with the 7600 used to take around 40% CPU on average with the nVidia Purevideo decoder. When the 8600 GTS is put in, SD MPEG-2 (576i25 PAL MCE recordings, DVR-MS MPEG-2) take 40-45% of the CPU. The deinterlacing is better but 'tis definitely not being done on the card even though the Purevideo decoder reports that 'tis in DXVA modes A/B.

His tests were on a Core2 Extreme. When talking hd content I'd like to see something on the lower end, like an x2 4400+.

I am looking at the 8600gts for my new HTPC setup. Someone mentioned the AMD/ATI R600 cards are due out this month. Anyone know the date these new R600 cards hit the street? Might help with my decision to stick with the 8600gts or not. Thx
