With 956 million transistors compared to 666 million for the RV670 (Radeon HD 3850/70) — both engraved at 55 nm — let’s see the variations in power consumption at the power supply (which includes, just as a reminder, the power consumption of the entire computer and the 20% lost by the power supply).
Consumption at idle has increased significantly, which is not a pleasant surprise – a total increase of 22 W (approximately 18 W attributable to the graphics card) for the same usage level (more or less nil), which is pretty disappointing, especially since it puts the 4850 back behind the GeForce GTX 200 for consumption at idle, which is a highly appreciated strong point of existing AMD cards. At idle, the frequencies of the 4850 drop from 625 MHz (GPU) and 1000 MHz (memory) to 500 MHz and 750 MHz, which is a much less aggressive throttle-back than on the GT200.
On the other hand, under load, running Test Drive Unlimited, the increase compared to the 3870 was no more than 12 W for a performance that was 26% better in this specific case, which is very good (and that’s despite the slight overclocking of the Asus test board, remember). Note also that the consumption peak we measured for the card (still running Fillrate Tester) was only 270 W.
But admittedly, again the 9800 GTX + did as well, and that cancels out AMD’s advantage. Note that the G92’s change to a 55 µm process does result in a slight reduction in power consumption, both at idle and under load (up to 8 W), which is predictable given the very slight increase in frequency. We should also underline the fact that in this specific test case (Test Drive Unlimited at 2560x1600), the 9800 GTX +’s performance/watts ratio was 11% better than the HD 4850’s.
$450 in Best Buy for a GTX 260.
And the 4850 is pretty close to the 280.
Ouu the 4870 is going to give Nvidia a run for there money
for the first time in a while.
P.S. +1000 -> 2222
MaxSmoothedFrameRate=62 in the Engine.GameEngine section
"it was unavailable due to the sloppy handling of this launch"
Seriously? AMD can't control if their retail partners screwed the pooch on the release date, because they were so anxious to get people this great product. They made sure the product was readily available well before the launch date.
They should be praised for not having a paper launch, not told that it was a sloppy launch, very poor form saying that.
Hell i went to best buy and bought 2 4850's on sunday, when the cards weren't even supposed to be available yet, the guy told me "they have been in stock for over a month in the back, they aren't supposed to be available yet but i can get two for you." Were the AMD police supposed to come and smack best buy on it's hand and keep me from giving them profits?
Sorry if i'm ranting, just put the blame where it belongs.
In french, but the graphs talk by themselves. Ho, and if you want a short translation = impressive and incredibly more efficient than Nvidia (if you compare the size of the GPU, yes it's A LOT more efficient)
