AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTMetro 2033
Paired with Crysis as our second behemoth FPS is Metro: 2033. Metro gives up Crysis’ lush tropics and frozen wastelands for an underground experience, but even underground it can be quite brutal on GPUs, which is why it’s also our new benchmark of choice for looking at power/temperature/noise during a game. If its sequel due this year is anywhere near as GPU intensive then a single GPU may not be enough to run the game with every quality feature turned up.
Metro ends up being an even better test for the 7800 series than Crysis was. At 1920 the 7870 ties the GTX 580 while taking a 17% lead over the GTX 570 and a much smaller lead over the 6970. The 7850 on the other hand is slightly behind the 6950, but is itself tied with the GTX 570 and well ahead of the GTX 560 Ti.
Interestingly, in spite of being built from the same architecture the 7950’s lead decreases some here. At 1920 it’s now only 13% ahead of the 7870, though in all likelihood it’s just enough of a difference that the 7870 isn’t going to be fully playable at these settings. As it turns out the gap between the 7870 and 7850 ends up being larger, with the 7870 enjoying a 17% advantage.

Enjoy, now go and buyImSpartacus - Monday, March 5, 2012 - link
Yeah, I'm trying to figure out if a 7850 could go in an Alienware X51. It looks like it uses a 6 pin power connector and puts out 150W of heat.While we would lose Optimus, would it work?

optimus is laptops only. You do not have optimus with your desktop.ImSpartacus - Monday, March 5, 2012 - link
The X51 has desktop Optimus."The icing on the graphics cake is that the X51 is the first instance of desktop Optimus we've seen. That's right: you can actually plug your monitor into the IGP's HDMI port and the tower will power down the GPU when it's not in use. This implementation functions just like the notebook version does, and it's a welcome addition."

In reality, if I owned an X51, I would wait so I could shove the biggest 150W Kepler GPU in there for some real gaming.
But I'm sure the X51 will be updated for Kepler and Ivy Bridge, so now wouldn't be the best time to get an X51.
Waiting games are lame...

Wrong. Read a review.....The bigger issue will be the orientation of the PCIe Power Connector I expect. I have a tightly spaced HTPC that currently uses a GTX 570 HD from EVGA because it was the best card I could fit in the Antec Fusion enclosure. If the PCIe power plugs were facing out the side of the card and not the back I would have not been able to use it. I expect the same consideration will apply to the even smaller X51kungfujedis - Monday, March 5, 2012 - link
he does. x51 is a desktop with optimus.http://www.theverge.com/2012/2/3/2768359/alienware...

EA really screwed AMD over with Battlefield 3. There's basically no reason to consider a Radeon card if you plan on heavily playing BF3, especially since most other games like Skyrim, Star Wars, Rage, etc, all run excellent on any $200+ card, with anything $300+ being simply overkill.The obvious best card for Battlefield 3 is a Geforce GTX 560 TI 448 Cores for $250-$280, basically identical in performance to the GTX570 in BF3. Even those on a budget would be better served with a low-end GTX560 series card unless you run resolutions above 1920x1200.
If I were AMD, I'd concentrate on increasing Battlefield 3 performance with driver tweaks, because it's obvious their architecture is superior to nVidia's, but these 'exclusive' titles are tainted.

screwed how? only the 7850 is slightly lagging behind, & historically BC2 was consistently a little faster on nvalso BF3 has a large consistent boost since feb14 drivers (there was another boost sometime in december, benchmark3d should have the info for both)

@ SamusBF3 isn't an Nvidia "exclusive", they made sure to remain vendor agnostic and participate in both IHV's vendor programs. No pointing the finger and crying foul on this game, it just runs better on Nvidia hardware but I do agree it should be running better than it does on this new gen of AMD hardware.

In the reviews here SHOGUN 2 total war is said to be the very hardest on hardware, and Nvidia wins that - all the way to the top.--
So on the most difficult game, Nvidia wins.
Certainly other factors are at play on these amd favored games like C1 and M2033 and other amd optimized games.

Once again, on the MOST DIFFICULT to render Nvidia has won.
