PhysX in Warmonger: Fail
Cryostasis is a title due out this year, unfortunately there is no playable demo. Just a tech demo. Next.
Metal Knight Zero, MKZ for short, was another game on NVIDIA’s list. Once more, no playable demo, just a tech demo. We need real games here people, real titles, if you’re trying to convince someone to buy NVIDIA on the merits of PhysX.
Warmonger, ah yes, now we have a playable game. Warmonger is a first person shooter that uses GPU accelerated PhysX to enable destructible environments. Allow me to quote NVIDIA:
The first thing about Warmonger is that it runs horribly slow on ATI hardware, even with GPU accelerated PhysX disabled. I’m guessing ATI’s developer relations team hasn’t done much to optimize the shaders for Radeon HD hardware. Go figure.
The verdict here (aside from: I don’t want to play Warmonger), was that the GPU accelerated PhysX effects were not very, well, impressive. You could destroy walls, but the game itself wasn’t exactly fun so it didn’t matter. The realistic cloth that you could shoot holes through? Yeah, not terribly realistic looking.
Look at the hyper realistic cloth! Yeah, it looks like a highly advanced game from 6 years ago.
Warmonger itself wasn’t a triple A first person shooter, and the GPU accelerated PhysX effects on top of it weren’t going to make the game any better. Sorry guys, none of us liked this one. PC Gamer gave it a 55/100. Looks like we weren’t alone. Next.

Yeah, I don't know why they're playing this off as an RV770 overclock. RV790 is indeed a respin of RV770, but hey if nV can get by with 1000 different variants on the same GT200... Why not mention the benefits/differences between the RV770 and the RV790? Disappointed.SiliconDoc - Monday, April 6, 2009 - link
I guess they didn't mention the differences ? Tell you what, when ati gets 999 more rebrands and catches up with their competitotr, we'll call it even, ok ?In the mean time, the 4870 crossfires with the 4980, and soon enough we'll have the gamer joe reviewers that downclock the 4890 and find it has identical results to the same clocked 4870 - at that point the red roosters will tuck their flapping feathers and go home.
I know, it's hard to see it coming, when all you can see is s tiny dot of red, in a sea of 1000 choices of green. rofl

According to info at other sites, the 4890 has 3 million more transistors (959 instead of 956, very little difference). It also has a somewhat larger die due to tweaks made to allow the higher clocks.Go to Firing Squad or Xbitlabs review, both have an certain ATI slide that explains the small changes in detail.

" Because they’re so similar, the Radeon 4870 and 4890 can be combined together for mix-and-match CrossFire, just like the 4850 and 4870. "I guess it's not a rebrand.

Thanks guys, good read.The piece on PhysX kinda mirrors my thoughts on it - its not worth basing a GPU purchasing a decision on it because it affects so few games. If you design your game around PhysX, you end up making a gimmicky game, if you design a good game and think of good ways to let PhysX enhance it, you can make something good like Mirror's Edge.
The way I think about PhysX is based on Amdahl's law, which says that overrall speedup of a CPU from an enhancement that affects only a certain class of application is affected by the amount of time spent using that certain class of application. In the case of PhysX, the amount of time spent using it is generally extremely low, and when it is used the effect isnt always noticeable or worth having.
NVidia's marketing tactics leave a lot to be desired frankly, although I'm not naive enough to say AMD never tries a little marketing manipulation themselves.

Why on earth would you compare a newly released Nvidia driver to that of an ATI driver from December last year and a Hotfix at that? The latest ATI drivers have had substantial improvements in a few games and surely they would have sent you an up to date driver with the 4890 review sample- somethings not right there. Also, where was the overclocking comparisons? (some reviews stating 1ghz core 4890 no problem). What about Temps and Stock cooling fan noise?7Enigma - Thursday, April 2, 2009 - link
I'm a bit disappointed with the ATI card. That is pretty much the Sapphire Vapochill model with increased core (actually it's a slightly slower memory setting). At least the GTX 275 is something different.bill3 - Thursday, April 2, 2009 - link
Wow lol..both cards are just rehashes. Calling the Nvidia card "something different" is a hell of a stretch.. it's just their same other cards with various clocks twiddled for the trillionth time.If anything the ATI card brings more to the table, as it offers much more clock headroom (1ghz is said to be well within reach) due to it's redesign, while the Nvidia card is nothing at all new intrinsically (aka it will overclock similar to the 285). Too be fair Nvidia's better clock-capable models (285) just came out a couple months earlier instead of now.
