The IGP Chronicles Part 2: AMD 780G vs. Intel G45 vs. NVIDIA GeForce 8200

General Performance Showdown
We've already compared the two most important aspects of these chipsets. Now it's time to look at the general usage performance of the platforms to make sure you're not sacrificing anything in going with one over another.
PC Mark Vantage does a very good job of testing actual application throughput in various categories and providing consistent platform results. We can see that our Intel G45 and AMD 790GX/NVIDIA GF8300 platforms are an even match with each leading in a variety of test suites. The 780G platform trails slightly thanks to lower than average scores in the Communication and Music test suites. However, the average user will never notice the difference in performance on these platform configurations, unless you realize that our Intel system configuration costs about $90~$120 more than their AMD/NVIDIA counterparts.

If you multiply it all out that gives Intel a throughput of 8 instructions per clock for G35, 10 for G45, 10 for NVIDIA's GeForce 8200 (where two are transcendental operations) and 40 for AMD. In terms of worst case throughput however, AMD falls down to 8 per clock (assuming the compiler can't feed the hardware 4 shader ops + 1 transcendental per SP) as does NVIDIA. This worst case rarely happens, but it is definitely worth noting.10 for nvidia => 8 for nvidia
AMD falls down to 8 per clock => to 10 per clock

wow finally a video playback comparison :-) TYI have a question one of you may be able to answer ?
In the "Hardware Accelerated Blu-ray Playback Comparison"
(CPU usage) the 780 beat the 790 in 3 of the 6 tests!
With the 790 using up to 9% MORE CPU usage, and in the
other 3 tests. The 790 beat the 780 by only .3% (well within a margin of error)
Up to 9% MORE CPU usage is A LOT!
I want to buy the 790 but this is a disappointment!
Dose anyone know why the 790 uses so much more CPU then the 780.
Is it's HD Acceleration sub-par ?
Heck in the "Crank DB" test all the cards beat the 790.
Please help TY

Do we know if the Radeon HD4xxx cards support output at 1080p/24fps?I did some googling and can't find anyone who can verify this

"do we know if the Radeon HD4xxx cards support output at 1080p/24fps?"this is exactly what I want to know also.

I just received a 4670 today to plug into my old PC that i'm slowly converting into an HTPC. In the display modes 1080p/24 is natively listed, but i'll have to get my blu ray drive in before I can truly verify that it works. Sure seems to have support though.Calin - Tuesday, October 14, 2008 - link
An Intel processor and chipset with an AMD discrete cardSkCom - Tuesday, October 14, 2008 - link
testing amd ddr 2 and intel ddr 3 is not fer test and amd made the 780 790 for usage with cheap cpu SEMPRON so why use phenom and rise the w power when simply can do the chep cpu psu ram and stillwatch HD movies surf and dissant gaming price perfom AMD 1 CHAMPION

Checked twice, can't find any punctuation in this post. I have no idea what you are trying to say.fic2 - Tuesday, October 14, 2008 - link
Apparently using a Sempron takes away your ability to punctuate, spell check or make much sense.Clauzii - Tuesday, October 14, 2008 - link
He says that by using a Sempron CPU (lower watt than Phenom), it would still be a nice machine for most people, and still be good for movies.
