AMD 780G changes the graphics game

AMD RELEASED THE 780G chipset yesterday, and it is going tochange the graphics game. The firm has done the seemingly impossible - made anintegrated graphics part that does not immediately draw ridicule from all sides.It is actually good.
The main trick AMD pulled out of the hat is to change the specs on what anIGP (Integrated Graphics Part) is. In the past, you took the lowest end of yourlast generation GPU and cut it in half to make the IGP. Gaming was awful, itbarely got out of it's own way, and was on the receiving end of howls oflaughter from anyone involved.
780G made the laughs stop. AMD decided to take a full GPU and put it on thechipset, so what you have is a full Radeon HD24xx (RV620) on board, videoacceleration, 3D and all. In the integrated GPU world, this means that the chipswill blow all comers out of the water. In my testing, they do, handily, but moreon that in a bit.
There are two variants, 780G and 780V, with the V standing for Value, orlower-end part. The graphics core on the G is labeled Radeon HD 3200, the V isthe 3100. The main difference between the two is the clock speed, G is 500MHz, Vis 350.
Both have enough features to choke a horse, 12 USB2 ports, six SATA witheSATA support, HDMI, DVI and display port, along with 22 PCIe2 lanes. The G hasUVD andHybridCrossfire as well, the V has those fused off. The one thing lacking is RAID5support, and that comes in Q2 with the SB750, the replacement for the SB700.
The 780G does very well in the checkbox feature list, it basically hits themall, but if performance is a dog, so what? Luckily, 780G is a performancemonster. We have one, a Gigabyte GA-MA78GM-2SH to be exact, and it looks likethis.

This one has it all, including the up-and-coming display port. My setupincluded 2G of Corsair XMS2 DDR2/1066 and the new AMD 45w 4850e CPU. On theaccessories side, we have a Lite-On DVD-R, a Western Digital 500GB RE2 HD andit was powered by a PC Power and Cooling Silencer 750W PSU in ATI red ofcourse.
Due to the limited time before CeBIT, there were only a few tests we couldrun, some of which fell flat. Sadly, due to AMDs decision to make all the coolnew features, Hybrid and CrossfireX, Vista only, these could not be tested. Alltesting was done on XP SP2, the broken, malware-infested OS was not used.

How well did it do? Right out of the box, no tuning at all, it hit 1197 on3DMark06. Before you sniff that you can beat that with a 8800GTX, well, keep inmind that this is a $89 CPU on a sub-$100 board. Think about that, four-digit3DMark06 scores for under $200, that is amazing.
Swapping out the 4850e with a Black Phenom 2.3, the score jumped to 1535.This particular CPU was able to hit 2.8 pretty easily, so with a bit of tuning,that score would go way up. By way of comparison, the 4850e with an HD3450 GPUplugged in, no Hybrid, hit 1739.
All of the combos played several HD-DVDs including the Dolby sampler andSerenity through Cyberlink PowerDVD Ultra without a hint of stutter or problems.The 780G + 4850e is about the cheapest way to HD we have come across in a longtime.
One of the most important questions on anyones mind lately is power, and theflip side of that, noise. The 780G does very well here, it is 100 per centpassively cooled so it is totally quiet, only HD noise and case fans to disturbyour pe ace.
Power draw is commendably low. One technical caveat though, the PCP&C PSUI have is a fairly high efficiency model, one of the best ones we have used.That said, PSU efficiency is not just related to the PSU, but also toutilisation. The closer to 100 per cent load you are, the higher the efficiency.At low loads, the efficiency of any PSU is pretty bad.
Because the PCP&C PSU is a 750W version, the wattages shown below aregoing to be pretty heavily skewed by PSU losses, a normal occurrence. Allnumbers were measured at the wall with an Exetech power meter, with max drawseen listed. If you put in a much lower draw PSU, these numbers would all dropsignificantly.
Back to the parts, how well did the 780G do? At idle with a 4850e, it pulled50.1W. Adding a 3450 took it to 67W, and a the Phenom brought the total to76.1W. These numbers are among the lowest we have ever seen.
For 3DMark06, basically full load, they drew 99.5W, 119.1W and 162Wrespectively. Under HD-DVD playback, the entire system not including theexternal MS HD-DVD drive drew 98.2W, 100.7 and 128.6W respectively.
The 3DMark numbers are insanely low, sub-100W for four digits of score issimply unheard of. The HD-DVD numbers however are too high. This is not to saythey are bad, far from it, just that there was a problem with my testing. Thebest explanation we have is a driver problem, the UVD/Avivo did not seem to beworking on the 780G GPU but it did work with the 3450.
This caused high CPU utilization, 80-90 per cent on the 4850e and 20 per centon the Phenom. Normally we would question if it worked at all, but several othertesters we talked to did not have the same problems we did, so this seems to beour problem, not ATIs.
With a more efficient PSU and the driver problems worked out, you could getperilously close to 50W under full HD playback. If so, that puts it at or aroundthe power draw of a stand-alone player, and is quite possibly cheaper as well.
Moving back to performance, there is much more to the 780G than just stocknumbers. Most integrated chipsets are roundly laughed at by anyone with a clue,and flat-out ignored by OCers. The 780G is not one that you would be wise toignore.
It is supported by the ATI overdrive utility, so OCing is a simpleproposition for almost anymore. 780Gs will OC like mad, 1GHz is not out of thequestion with a simple fan on the northbridge. We have seen one hit almost1100MHz with no exotic cooling, and if you can't hit 800, you aren't trying.
At those dizzying speeds, the 780G will hit almost 3000 in 3DMark06, with anon-OCed 3450 beside it, you can hit 4500. Think about that, under $250 for 4500in 3DMark, low-power use and full fanless HD playback. What more an you ask for?
In the end, AMD did right with the 780G. It set the bar so high that Inteldoes not have a prayer of a chance to catch it with the G35/45 - not a chance.Intel may have the CPU speed crown, but on the platform side, AMD creams them.
If you look at the total system, the 780G + 4850e is one hell of a mediacentre box. If you pick the right mobo, there is little this chipset can not do.You can run it fanless, put in a fanless 3450 GPU for light gaming, and get itall for a pittance.
If you are looking for a media centre, this combo should be at the top ofyour list, it really is that good. The only problem is a lack of Linux driversfor the media acceleration side of things, but with luck that will come soon. Inthe meantime, there's not a better all-round box for your living room.

Although this is impressive, I feel AMD and ATI wasted their time with this, unless Crossfire compatible cards can connect to this video. THEN I say this was a very smart choice. Get this to work with XP and that'll be even better. I blame ATI why this isn't Linux compatible. AMD should be researching more on getting faster speeds. Other than their quad cores, they aren't very far behind at all. Intel seems to be wasting their money on getting more cores in one die (even quad core seems unnecessary except for server use) so AMD should be using this moment to their advantage. ATI is also very close to beating NVIDIA, and for their price and power usage, they are winning. AMD/ATI are so close, I expect more than this.
