Leak: ATI Radeon 4800 Gets 480 Stream Processors

[homerdog]

Come on guys, since when did we start adding the framebuffers together on multi-GPU solutions? It's two duplicate 1GB framebuffers, not one 2GB framebuffer. Unless something has changed with the way ATI does multi-GPU...

As for this whole chipset address limitation argument, that's ridiculous. As Scotteq pointed out, the MCH is only responsible for system memory i.e. the stuff that goes into the slots.

I really don't know anything about this but what if there are two 256bit memory controllers one for each 1gb of ram ? Would that be considered 2gb of ram?

It would be considered 2gb, the way the GX2 and X2 are now considered 1gb. There may be 2gb total in the 4series X2, but each GPU will only be able to access its own 1gb via its own 256bit bus.

Simply put, for dual GPU cards take the amount of VRAM that is written on the box and divide it by 2. That is how much VRAM the card can actually use.

When ATI says that it will be 1.5X faster than previous, I supose they know what they are talking. So 4800 is not so much faster than current Nvidia offer. But should a little bit faster, so the 1GB + 1GB memory is indeed relevant solution because some games can actually be playable at higher resolutions.
What this allso means is that Nvidia has to make some real GPU release in near future, so we can actually see a little bit faster GPU:s in near future.

That 800 million transistors count allso means that these will be more expensive to produce that previous generation, so even we get more expensive graphic cards, or there is thinner profit margin, because there is not any development in production part. Same 55nm as before.

The 4850 512MB GDDR3 should retail for $229, the 4850 512MB GDDR5 will set you back about $249-269. The big daddy, the 1GB GDDR5 powered 4870 will retail between $329-349.

When it will become available the 4870 X2 will hit the market for $499.

Those one GPU units prises seems to be somewhat possible, but that X2 seems to be too low. If you compare 3870 and 3870 X2 the price is allmost double, so $600 or even more is what I am expecting it to be. So we are back in "normal" highend prices...

Seriously, anyone looking at DX10 PCI-E 2.0 card should not be running 32bit xp....or even 32bit vista for that matter. The system memory limit for 32bit OS's is 2gigs, 64bit OS's will take as much memory as you can throw at them, there is no OS limit, only limited by what is actually available.

As for intel limits, i don't know for certain but it wouldn't suprise me at all if they are limited to 8gig since from their point of view 32bit stuff is all anyone should need because 32bit stuff is all that they are capable of doing well.

But these ATI cards...are intended for use on AMD systems....AMD chipsets with AMD cpus...which if anyone bothers to compare benchmarks, both real world, and synthetic it's painfully clear that the cpu's of the same clock speed AMD are about 30% cheaper then intel with little or no performance difference. The only intel cpu's that have a staggering gain are the flagship chips that cost $1000+, and still don't surpass 30% performance lead over AMD's $200 chips in real world apps. Those $1000+ chips have marginal performance gains over almost identical intel chips that cost half the price. Though intel still FAILs horribly when it comes to memory performance, as even 750mhz DDR2 on an AMD system beats out intels fastest setups.

By my reckoning the 4870 should be about twice as fast as the 3870.

3870 had 320 shaders @ 775 - 320 * 775 = 248,000
4870 has 480 shaders @ 1050 - 480 * 1050 = 504,000

It also has twice the texture units - so long as nothing else bottle necks it i reckon it will be a good deal quicker then the 3870x2. But i dont think it will be mind blowing. Thats said if it is well priced, doesn't make much noise, or use much power (should be a given) it should be a very solid product. It will be the best card around until nVidia crah AMD's party and launch the 9900 series.

4Gigs, which includes addresses for the system as well as RAM. Depending on configuration a given computer may have roughly 3GB of addresses laft over once the rest of the system has been handled.

Current consumer offerings from MSFT are set up for 128GB of address space.

You're confusing hardware and software - The hardware is, and has been for quite some time, fully 64 bit capable.



As for the rest - Fanboi spew

Why don't you people understand the secret behind this?
They wanted us to buy a new product more often. Why do you care about whose faster or slower, how fast do yo want anyway? i got 7900 once. sure its "fast", well look here i got something "faster" now. You think this new AMD/ATI will not run "fast"? compare to what? your geforce? i'm sure it's fast and enough. And as for u geforce people go out and buy faster "geforce" next mounth.

pardon my english

I used to like ATI when Crossfire could make nvidias one card Drivers good go. Yet ,now nvidia has worked out sli hybrid & killing ati. I can see why with 5X redundancy, maybe it helped in CrossfireX when it first came out, yet if nvidia can stay stable, with more TOP End, its price/perf, Hey- Think of !.0 Crowd, Am I supposed to save it in doggie Bag, its so hot? Probably NOT.

He makes little sense and a lot of false statements... or at least he has on the forums.

 

[r352alit]

well i really don't care who's faster. what i really care is who's the cheapest among the highest price, who's the lowest power consume among the low power consume. And finally as long as i can play game and compatible with any game and OS i've use, i'll take that product.
The fact thats both, nVidia and Ati, release new product every 6 month is really really bothering. I mean any company thats release a new product every 6 month, thats doesnt sound they are good w/ their research departement, but they are really really out of money for cover their expenses. In this case, whos got bullied????

I do like the new series just because It seems like ATI got lucky with the 3700's series. They came with some issue's that now ATI is patching up and fixing and making them much better, I see a x2 for the Memory which would be cool to play games at high resolutions. I'm sure ATI will price competivly seeing as they have done with 3000's. In retrospect ATI is taking action and made some mistakes but is getting better.

I dont want 2GB GDDR5 (ok i want 😀) I want more Bit Interface! Why not MBit? Why not 512Bit? On ULTRA 8 Series from nVidia 384Bit brings more (with G80) than **** 9800GTX with G92 256Bit -.-

Memory bandwidth = DRAM frequency x memory bus width.

DRAM running at 2000MHz on a 256bit bus will yield the same performance as 1000MHz DRAM on a 512bit bus provided that the latencies are the same (which is not the case with GDDR4, but I don't know about GDDR5).

Large memory buses are expensive in comparison to faster DRAM chips.

 

[emergancy exit]

it looks like NVidea waits to have the "last word" they wait for ATI to come out with something, then nvidea trys to "kill it" then they wait again.

i dont think ATI has "single card solution" in mind. from what i have read ATI scales multiple GPUs beter that Nvidea so althogh 1 on 1 card comparisons between nvidia and ATI will put nvidia on top 3xATI vs 3xnvidia is probably where the compitition is most fierce ... and then ATI can bring it home by adding a 4th GPU for that extra muscle; something ATI can do cheaply where quad SLI will cost you your first born.

4x9800 and 4x3870 compitition is already very close and considering ATI comes very close for 2/3 the price who would you choose?

i cant wait to see theese new cards in action. the price is upped slightly but still less than Nvidia and is definently going to close the gap if not pass it.

on a side note 2gb video cards have been out for years as "workstation graphics" so all of the OS/chipset issues with mass graphics memory have been solved for a while now.

we are starting to workstation type performance being released in the mainstream market

 

[Guest]

So,, this is all well and good but im still wondering if i should buy the nvida 9800 gtx2 or wate for the a.t.i 4800x2 to come out. im not worried about spending a few mor dollars on either card. i justwant somthing thats going to be sharp and fast. so if anyone can direct me in the right diriction, please, some advice would be good.. oh and im a heating tech not a computer tech, so english please. thanks

[citation][nom]Andrius[/nom]What does one need a 2GB framebuffer for? F@H? 64xAA at 2560x1600? It's a waste of memory. XP 32bit will only have 1.5GB system memory left! And most current Intel chipsets have 8GB limits. 24 months from now when maybe something comes out that could use it's 2GB framebuffer it'll be just as obsolete as a 1GB version.[/citation]


Pfft who uses 32 bit anymore. i been using 64 bit for over a year now and there is no way in hell im going back to slow laggy 32 bit. BTW some of us do run every game we have at 2560x1600 i have a 30" LCD with that res. BTW next gen chipsets will be up as high as 24gigs memory considering the i think 4 and 8 gig moduals have come out a couple months ago. So hell look for 32 gigs in a system if the price stays low on ddr2 at least dd3 dont think it will happen for a bit. I run 8 gigs now and 1 gig on my video 😉 course its crossfire so tecnicly its only 512 meg buffer which kills me in high res and highest quality settings. If i wanted to play in cheap crappy low res graphics i would just get a ps3 or xbox but i got a computer to say wow everytime i play a game.
