Hardware Accelerated Blu-ray Playback Comparison
All three platforms we're talking about here support hardware Blu-ray acceleration, but how much of an offload do they provide? To find out we looked at CPU utilization while playing all three types of content (MPEG-2, VC-1, H.264) with a Core 2 Quad Q9450 on the Intel chipsets and a Phenom X4 9950 BE on the AMD/NVIDIA platforms. Because of our CnQ issues we've provided data with it both enabled and disabled. Intel's EIST is always enabled.
The breakdown of video decode offload is as follows: AMD offers the best in terms of CPU offload, followed by NVIDIA, then Intel with the G45. Remember that the G35 has no hardware decode support, so that's the reference point.
With CnQ enabled Intel takes the lead; however, this isn't a recommended configuration.
The same holds true for MPEG-2 and H.264 playback: AMD's 780/790GX offer the most CPU offload, followed by the GeForce 8200/8300 and then G45. Turn on CnQ and Intel takes the lead.
All of these numbers are low enough that the chipset you pick shouldn't matter - as long as you have hardware acceleration you're golden, but let's look at power consumption to see the impact of the CnQ issues on the AMD platforms.

A fair comparison? Don't think so! A AMD processor with a 140 Watt TDP and a Intel processor with a 95 Watt TDP?? I wonder why the intel chipsets seem more power efficient? If you are testing the performance, ok seems fair, but power efficiency should be measured with two processors with the same TDP. I am convinced that if you did the same test with a AMD 4850E the AMD would beat the crap out the intel versions on power consumption. But yet again, that would not be fair. So keep in mind that this review is not to be taken al to seriously!axiomhk - Tuesday, October 28, 2008 - link
Hi, what amazes me is that it seems no reviewers of the AMD IGP chipsets have caught the serious 2D issues referred to here:http://forums.amd.com/game/messageview.cfm?catid=2...">http://forums.amd.com/game/messageview....9&th...
However, the only channel that we consumers / mere mortals have to put pressure on AMD is to send feedback to the Catalyst team. Nothing seems to get done and there is not even any acknowledgement that this issue exists across the HD3200/HD3300 IGPs no matter which manufacturer.
The 3D performance is hyped up and that's all very well when the chipset has shown that it can deliver, but in fact many users will spend a lot of time on 2D activities which truly suck. This makes a lot of users regret their purchase.
What the renowned sites such as anandtech and tomshardware can do is try to reproduce the issues, then use their direct contacts to try to see if this issue is being addressed and update the parent article accordingly. Is it possible? Many thanks. GM - Hong Kong.

"The keyboard is not available after drive recognition until the Windows startup routine"Try a different keyboard, or a PS/2 keyboard. I had the same problem with two MSI 750a boards and some Razer USB keyboards. No keyboard until Windows. I had to fix a BIOS problem and had to borrow a keyboard - Logitech G15 USB keyboard worked fine.

Is this not a bit ODD to Compare a $260 to a Lowly Under performing [B}$173 CPU... Geezs This is Grossly inaccurateThink about the BOOST to Post Processing and It differs a Whole Lot to the Post processing capability

Yeah, it would have made more sense, IMO, to use lower end processors like AMD 4850E or Intel E5200/7200 which is what most people would use in a HTPC.But if you want to do encoding on your HTPC also, I can see the need for a quad core. But not for your average "movie box".

Really, this thing came out like 6 months ago it seems and finally we get some video benchmarks on anandtech. I know it has been commented that it did not work right for months because the video drivers were terrible but I can not believe it really took that long. When I had to get a HTPC, I just bought an Athlon BE and a 780G board. Much cheaper and adequate. Which in hindsight the P45 may have performed better, an Intel CPU and a Core 2 CPU would have driven the price up quite a bit.Kreed - Tuesday, October 14, 2008 - link
Gary, what are you hinting at with the following statement?"That leaves the Intel G45. If you are an Intel fan, this is your only real IGP choice... for the next few days at least."
Are you suggesting that Intel might be releasing a new IGP over the

Oops, i didn't get to finish the comment. Here's the comment in full:Gary, what are you hinting at with the following statement?

The NVIDIA MCP7A (GeForce 9300/9400 IGP) boards supposedly launches today. They're sockey 775 boards. I'm pretty sure AnandTech will have a review up soon.http://www.silentpcreview.com/forums/viewtopic.php...">http://www.silentpcreview.com/forums/viewtopic.php...

AMD 780G and 790GX have 8 stream processors (5-way) for a total of 40 possible ops per clock... NOT 10
