Hope your french is good, but the graphs are in english anyways, not like its complicated


Bottom line from what I can see: it looks like the 4800 series best feature could be antialiasing scaling, if the 4870 outperforms the gtx260 with AA enabled then Nvidia could be in trouble :p

Parlez vous français?

If this card is $200 as rumored, ATI has a real winner on their hands...

I don't understand why it totally fails (along with the other Radeons at that) at AA in Bioshock and STALKER though. What's up with that?

I've been seeing the 4850 a lot. I want to see the 4870. The GDDR5 RAM, clocked at over 3 GHz if memory serves, should offer a nice boost. I also want to see what my AC accelero S1 does for it....

3870MHz DDR5 was the rumor (had to look it up. Odd for the ram to be clocked at that exact speed...)

I'm waiting for FSB's that have a frequency of 666 MHz. :whistle:

You'll be waiting a long time. Intel and AMD won't have them, you'll have to see what Via does.

Nvidia uses a hack to use AA in those. I'm sure later drivers would fix it though since it's using AA through ROP once again.
June 18, 2008 11:54:33 PM

Wow just wow. 4850 sometimes neck and neck with 260gtx and most results very close to 9800gtx 8800ultra performance. AA performance has been improved drastically and even better than 9800gtx or the ultra. I just wonder what higher clocked 4870 with GDDR5 would do.
June 18, 2008 11:58:09 PM

I wouldn't go so far to say the 4850 is going to be neck and neck with the gtx260 at high res/high AA -

However I do think the 4870 could best the gtx260

I hate to say this, but to me the 4850 is not a card to get that excited over from a high performance point of view; the 4870 however could be really awesome.

I'm just waiting to see if the 4870 CAN beat the gtx260 with 4x AA enabled or not; if it can consistantly beat it I might go with a 3x pci-e x48 board and dual up 4870s then add a 4870x2 later on this year.

If it doesn't though, i'm going gtx280 SLI :o

I think ATI has a second coming, the 4850 looks very promising. I just am hesitant to get that with the big brother 4870 coming soon. $229 for a 4850 and $449 for GTX 260. For the performance difference?.....Really? I think my 7900gs is ready to find a new home. :bounce:  .........I'm not a fanboy of any brand, my last pc was a AMD cpu and Nvidia GPU, this pc has an Nvidia card, for the time being and an Intel CPU.
June 19, 2008 12:05:16 AM

In couple of those benchmarks it sure does go neck and neck with 260gtx. We are talking about a card with 16 ROP and 256bit memory bus with gddr3 here. Performance is feat in itself. I would love to read what my usual sources of what improvements had been made.
June 19, 2008 12:07:02 AM

Ovaltine...(2) Two, GTX 280's will be the new thing responsible for Global Warming....give it time, make the educated purchase. :) 
June 19, 2008 12:21:27 AM

Now as long as they don't show any crossfire reviews I can still say my GTX 280 is the best. I wonder how it'll do against the 4870x2

4850 should be $199-249 not $299...4870 rumored at $299- 349

Don't you think that a 512mb card is going to bottom out at 1920*1200 + res with AA enabled?

and there might be jagged performance in crossfire at those details too

Anyways, maybe i'm wrong - maybe I just don't understand the physical logistics of it

AMD doesn't choke as much as Nvidia GPU goes far as how much vram it needs to do certain resolution. For AMD 512mb is plenty. Nvidia might need more than 512mb at times depending on the game.

The 23rd is taking too long to get here! Reading on here it seems Nvidia has more of a bandwidth problem that ATI does. Either way, I have a 20" monitor so a 4850 might be perfect for 1680x1050 with 4XAA
June 19, 2008 12:32:46 AM

I see, just architecture difference I suppose really huh

I guess that would explain 3870x2 doing well in WIC with AA enable 2560*
June 19, 2008 12:34:57 AM

looks like that will fit an x2 card plus 2 singles, but the SATA connectors are in the way

newegg's other stuff seems to be ddr3 boards which= money down the toilet lol

I guess I should research this more, although i've users lots of ATI cards i've never done a crossfire system

Yep, hurry up 4870 x2...if the 4850 is that good, then the 4870 x2 should be REALLY stout !

June 19, 2008 1:05:39 AM

Only problem I see is if everyone wants it then you will see higher prices than predicted and in that case I will end up with a new 8800GTS.
June 19, 2008 1:09:05 AM

not necessarily, you have to bear in mind that the 4800 series is not a hard card to physically produce; meaning the materials yielded well for them


This is why the price is lower to begin with

hey royal clown lol. 8800ultra has "ULTRA" which boosts even more than x. So according to theory it should be faster than 4850 lol. Alright. So how can a card with lower bandwit outperforam a card with a higher bandiwth at hgih resolutions and eye candy? Oo


Well say bandwidth is a tube like you say:

but the data the cpu can put out would then be the water, you could have a tube the size of a fire hose with a trickle or a much smaller tube that is gushing... which might actually be flowing more water...maybe it's like that.
June 19, 2008 1:33:50 AM

well yah, but what I am gettn at is say that the firehose is only gettn a few drops vs the garden hose on full blast see ?

Yeah i agree with you, but then that water should be really speedy :p  And every tube has a limit of amount of water it can let trough.

I saw some 4850's listed for right around $200. Claimed they were in stock too. I'm more worried about the 4870's price, especially early on. Hopefully ATI will be smart and try to keep the prices reasonable so they can gain market share and put NVidia's prices in free fall. I really like NVidia's answer to all this, a magical 9800GTX driver. Sounds to me they are going back to their old ways.

Haha, maybe. I wonder how much difference the faster ram would make. The FX-60 does have the bigger cache(s), though. It's hard for me to part with my FX-60, though. I like its name too much. All the current ones are too boring/conventional.

I see you have a 780G too, but with a card. I'm suprised how well the ATI 3200 graphics does in mine, especially with the major OC I've applied. Very power efficient too (especially compared to my gaming comp).

I remember reading something that may turn out important. Im not sure where I read it, Ive been reading alot lately , so dont ask, all I can say at the time I read it, I took it as gospel, and maybe somebody here will remember. Anyways, when they implemented the cf on the 3870, they used pci1, not 2, and they said theyd made a mistake by not using it. This could be that magic fix, or at least, in part, where the bridge chip has opened up the x2 cards

Yah, it has the cache, but the X2 has the archetectural tweaks , plus the extra core which can be used by newer games, and even if not directly, can slit up the OS duties and free more of the cpu time for your game !

yeah, i just wish that 780's worked with nehalems...lol; I love the chipset, friggin fast, and the 780 does game well with a card, I can Crysis on VERY high on my 17 inch, that's maxed EVERYTHING at stock speeds on everything.
June 19, 2008 2:41:57 AM

Outstanding performance with AA enabled! It is performing with 3870x2, 9800GTX, and the Ultra, which is pretty damn good for a ~$200 card.

If these numbers are right, ATI has definitely fixed their AA problem, and the 4850 is looking pretty sweet in Crossfire.

One thing to remember here. It comes close to the G260 a few times, but down the road, with either DX10.1 or DX11, this card will actually be outperforming the G260. Not bad for 200 bucks or less
June 19, 2008 3:15:08 AM

and awesome performance at 19x12
June 19, 2008 3:38:43 AM

Yeah this card is pretty good, nvidia is going to feel some pricing pressure. Low priced GPUs for everyone!

Not necessarily when you consider Oblivion raw performance which are shader heavy compared to 9800gtx. It just seems more efficient than Nvidia's big numbers with big everything.

2900xt and 3870 texel filtering rate was low but it's peak texel sampling rate was more than 8800 ultra. This number could have doubled with 4850 along with its filtering rates. It's AA performance is much better than Nvidia's AA numbers which has nothing to do with shader.

I don't disbelieve you, but why will this be so? Simply because the 4850 will have DX10.1?

Or is there something else about the specs that I'm not thinking about?
