Why stop at synthetic benchmarks? why not add a wiki stub saying "And its 100% better folks, fact proof positive" and a link to the inquirer?

In any case in actual games the 4850 preforms about as well as a 9800gtx, and since the 280 is, in crysis, over 40% faster than a 9800x2, I doubt the 4870 will be coming near it.
But I'm almost sure that for price-performance, AMD will be better.
 


okay then why intel is working on nehalem, when there is no need to release it. And why would nvidia want ati to get back up ? Competition - less money for Nvidia.

Just looking at these specs 4870 would be very close to 260gtx. 260gtx is really a good match for 4870. It's bandwidth is very similar and spec wise it kind of balances out. Bilinear fillrate is what you consider low quality fillrate for older games but FP 16 blending fillrate is what you would call higher quality for use with HDR. The games today have a bit of both so expect 260gtx to have higher performance in older games and higher max fps but I expect 4870 to have higher performance in newer games and better minimum frame rate and even surpass 280gtx in games like GRID that consist of HDR in the entire game.. Pixel fillrate is very helpful in higher resolutions and AA but RV770 has much better AA performance than Nvidia this time around not to mention more efficient with their ROP as witnessed by 4850 that has higher color fill than 9800gtx with less bandwidth. We weren't that shader limited in the first place. shader help but the biggest gains are usually scene by fillrate.

 
2 interesting points:

1) newegg had several brand 4850s at $179 after rebate, and even one at $169 for a day or two. Not anymore though. A couple lucky bastards must REALLY have gotten a steal.

2) it will be interesting to see when the 9800GTX+ actually hits the market in quantities. The last I saw is that it won't see retailers until the end of July. With that kind of reasoning, perhaps ATI should just "release" their 4870X2 now.

My completely uninformed WAG is that the 4870 will be about a third of the way past the GTX260 to the 280.
 


Actually I've got a q9450 but the only reason I didn't get an 4870x2 is because when I play a game that isn't good at Crossfire it performs as good as the single gpu card and the same with the 9800GX2, I just want guaranteed top performance in most games regardless of SLI/Crossfire compatibility.
 

If the x2 outdoes a GTX280 in most games, since most games work with cf/sli, then its the way to go, and when it doesnt, youll have to live with killer performance better tha n anything BUT the g280, to me its a nobrainer
 

Supposedly the 4870x2 connect the 2 gpus in a new way, does not use bridge, shares ram, and scales like a single gpu.
 


A significant price cut on the GTX200's will likely have to wait until the 55nm versions come out or Nvidia will be losing money on each card. Remember that even if Nvidia was having a 100% yield rate it is still costing them well over $100 per GPU before it is even put on the PCB due to the massive size of each chip and the high cost of wafers. In reality however, Nvidia likely has a yield rate of far less that 100% and hence is probably not making a huge profit on each of the GTX280's right now despite the extremely high retail cost.

 



Intel is working on Nehalem because the Core arcitecture, while good, is eventually going to hit a wall. Basically, its time for an update, as well as the fact that the FSB is really, really, really getting on in years, Nehalem doesn't need an FSB anymore, which is mainly why intel is making it.

And no, Nvidia never did want ATI to get back up, they underestimated them and thus, screwed up on the final lap. :kaola:
 
Im afraid to say, but i dont think that Nahalem will improve on Core 2 for single threaded apps. And that is what counts the most because most apps are single threaded.
 


I believe you are very close, as usual. I believe the 4870 will tie the GTX260 in older games and get higher performance in newer ones. Where heavy AA is used I believe the 4870 will beat the GTX280 half the time. Somewhere between your opinion and mine will be the almost assured performance of the 4870, atleast that is what it would seem.
 


I'm pretty sure that Nehalem will have much higher clocks than that, according to most of the "news". Also there is no way that I will ever believe that benchmark is accurate, or even ever MADE. I highly doubt nehalem has been benchmarked by anyone other than Intel considering it is half a year or more away from the market.
 

I think we might be in danger of overhyping the cards, to the point where they dissapoint, kinda like how the 280 was overhyped...yea. But still, here to hoping the well-rounded 4870 beats the 260! which it was never meant to do. We are hopeful because the 200s dissapoint.
 



Post of the day. Here's your award: http://www.youfail.org/ 😀

Did I ever say that Nehalem was going to kick ass? I merely said that Nehalem is going to replace the Core series, and get put the FSB to rest.
How does that count as trolling? :heink:
 


Obviously you didn't read the whole thread, I was responding to this gentleman several posts above.



Is it still trolling? 😗
