look at the x850XT PE beating the 7800GTX in the last graph BF2 1600x1200 with AA/AF...strange indeed...

 

[coomar]

the last time they did rome: total war, i guess its hard to benchmark accurately for

still pretty good

Ok, in the very first graph for Battlefield 2. Did anyone notice the X850XT scores?
Check this out.

Battlefield2 Pure speed (no AA no AF)

1024x768............90.7
1280x1024..........82.6
1600x1200..........54.5

Battlefield2 4xAA 16XAF

1024x768............89.3
1280x1024..........72.5
1600x1200..........61.3

Anyone else notice something wrong with this?
They are trying to say that the X850XTPE is faster with 4XAA and 16XAF than without it here. Someone please tell me I am reading this wrong.

I'm not discrediting X-bit because I generally like their reviews. I think they may have made an error though.

should email them

does look very wrong tho :thumbsup:

 

[theMan]

yeah, i noticed that too. its also strange that it was beating the 7800gtx sli. weird...

 

[imported_Kensai]

They're not unleashing the full potention of a 7800GTX SLI...
20X15 @ 8X AA, 16X AF is where we see some changes. I believe you can force 16X AA too.

 

[Pabster]

No way the X850XT puts up that kind of figure @ 16x12 with AA/AF enabled. Definitely an error.

 

[Polish3d]

Yeah weird... anandtech shows 39fps or something for the x850...still one would expect the GTX to do a tad better for the price, although it must be said that battlefield 2 doesn't seem to like AA at forced resolutions (or maybe at all.)


For me, going simply from 2aa to 4aa with nothing else changing (everything on ultra high except dynamic shadows and MSAA) causes a huge drop in FPS literally from 99.9 to 60-70fps

 

[Polish3d]

You know, when you involve AA @ 1600, the GTX really doesn't do that much better than the 6800 ultra... which pisses me off for the money. I'm actually going to sell my GTX for a better card once a decently better one comes out... The GTX is a very fast card but for the price I paid I would like more than a 30% increase over the 6800 ultra when AA gets involved.

I agree...I don't think the 7800 GTX is bottlenecked (with BF2), it's just not performing up to par with last gen's increases (not surprising because it's only been a year). AA@1600 isn't that stressful (relatively). I'll wait for something better too, hopefully that will be the R520. I'm not going to get a card until it will max-out transparency AA, 16x AF, and still play at 100 FPS. Though I haven't seen it tested, I doubt even the 7800 GTX can perform that feat at 1280x1024. That and that only will make me be happy with my $300-400 purchase. I'm preaching to the choir. I'm just sick of slowdowns. I want a card to last me a while. Pick up the pace, ATI.

 

[CP5670]

lol, now I don't feel so bad for having a lowly 6800 GT.

I think the 7800 GTX is much better with high resolutions than AA. Maybe it's because the memory still isn't much faster than the previous generation? There aren't any 19x14 or 20x15 tests in this roundup, where the GTX really pulls far ahead of everything else.

Hey, I have a 6800NU.

About AA: That may very well be the case. I'm not sure if memory bottlenecks AA, or if it's the GPU itself. SSAA (Supersampling AA) puts most stress on the memory because it has to render at a very high resolution, and then the GPU blends pixels. Note that SSAA is basically a higher resolution.

 

[ddogg]

yup definetely they've made some errors in those benchmarks. have to give them props though for conducting such a big test.

That's what I expect too, for a top-end card to perform w/ all things maxed out at high resolutions at ~100fps, because if it only gets 60fps, well wtf is going to happen when newer games come out 3 months later.

Although I have a hard time believing Bit-Tech's benchmarks because they show 89fps while anandtech's show 39 for the same settings.

 

[Polish3d]

Perhaps that's why there is such a huge disparity between 2aa and 4aa in BF2 for me...maybe...

I hit my 99.9 fps that I expect at 1680x1050 High quality MSAA with 2x anti aliasing, but at 4AA, I drop to around 70... 30% is a huge drop for that it seems

 

[xtknight]

60 FPS still feels very jerky to me...I demand at least 75 in any game I play. 100 FPS avg is definitely preferable, so I have some headroom for intensive scenes. And don't give me the "your eyes can only see 60 FPS" BS.

Hey no problem. Your eyes are just different from everyone elses on the planet, but you go with your bad self!!

[CP5670]

I don't care much about the average but really want minimums of at least 60 in any FPS. It's interesting that even two 7800 GTXs can't come close to that in FEAR on just 1024x768 without AA.

It seems that the 6800/X800 generation of cards take a huge hit above 16x12 but the 7800s don't, which to me is the main attraction of those cards. I know that 16x12 with 4xAA/8xAF is frequently faster than pure 20x15 on my current card, although I far prefer the latter setting.

About AA: That may very well be the case. I'm not sure if memory bottlenecks AA, or if it's the GPU itself. SSAA (Supersampling AA) puts most stress on the memory because it has to render at a very high resolution, and then the GPU blends pixels. Note that SSAA is basically a higher resolution.

Does the standard MSAA work in a similar way?

From what I've (tried to) read, it sounds like the same thing, I'm not sure what's different. All forms of AA involve blending pixels though.

 

[Kalessian]

I think it's interesting that 7800GTX SLI is MORE than twice as powerful as a single 7800GTX in that last D3 bench. I would not have imagined that the whole could be more than the sum of its parts.

7800GTX:.......7800GTXSLI:
57.6.................125..4

I don't really see what the issue is. It's well known that memory bandwidth is not what holds back game performance these days. I mean, the numbers seem a bit high overall, but AA/AF these days should put a minimal hit on FPS with modern cards.


EDIT: Ok, that explains it. They're not testing above 16x12. 7800 Series isn't being pushed yet. Still CPU limited.
