ATI Radeon HD 4800 Series Video Cards Specs Leaked
Thanks to TG Daily we can now talk about the very soon to be released ATI HD 4800 series of graphics cards with more details. One week ahead of its presumable release date, general specifications of the new cards have been revealed. All Radeon 4800 graphics will use the 55nm TSMC produced RV770 GPU, that include over 800 million transistors, 480 stream processors or shader units (96+384), 32 texture units, 16 ROPs, a 256-bit memory controller (512-bit for the Radeon 4870 X2) and native GDDR3/4/5 support as reported before. At first, AMD's graphics division will launch three new cards - Radeon HD 4850, 4870 and 4870 X2:

just a random guess
:laugh: i did this shot a few minutes ago :D Today is 2008. april 25. :D The regular user goes to nvidia.com for the newest official, don't searches the net for betas and modded inf drivers. (what nvidia drivers are there anyway? beta, modded inf beta, official beta, whql, official whql :eek: :twitch: )
I had a 7900gt for almost 2 years before my hd3870. There was a 9 months period with no official whql forceware. 9 months! There was a lot of betas though, all of them ended with BSOD (i tried them).
Now i'm with ati for 2 months now, and had no driver issues from cata8.1 to cata8.4.
I just like to get a new driver every months.
and out of all the only one that i had fun with was the 8800 gts g92 , all others except 9800 gx2 wud play fine but have weird problems now and then ............. the 9800 gx2 was WELL if i put it in words nv fanbois will be all over my rear end so ill leave it to your imagination , back to hd 3870 x2 and happy .
9800GX2 Vista 32bit driver.:confused:
And yeah, although off topic, the number of Vista crashes does not give an accurate measurement of which driver is more prone to failure. For a pool of 100 people submit a driver crash report over one week's time of time, 70 are Nvidia users and 30 are ATI users (A rough installment base). You can draw from that data that 70% of crashes were caused by Nvidia, even though both companies are suffering a 1 crash per week ratio, therefore invalidating the 30% vs 70% argument. A proper example would be if 100 people submit driver crash reports over one week's time and 140 of them are Nvidia users and 30 of them are ATI, then you can say Nvidia's crash ratio is 2 per week while ATI's is still 1 per week. The key to this example is that the number of users needs to be given before hand and possibly also unique crash counts.
Longer time between releasing probably saves your avg joe dipshit from problems. I can see them going to the website 3 times a month installing new drivers without actually uninstalling (cleaning) the old ones (which is definitely partly Nvidia's fault and ATI, etc) and causing mayhem.
If you're smart enough to be updating drivers (properly), then you probably don't need to go to the official sites to get them (I know I never do).
i bought a 3870 brand new not long after release for $250, nice to see that the next top model (4870) will be over $300++
and yes, MSRP says a LOT about what the card will do with respect to previous releases.
After running dual 1950 PROs, I've become a believer in Crossfire's ability to improve gameplay with higher resolutions; so I'm aiming solely at a minimal dual-GPU card.
two dual-GPU cards, preferably :D
Again, though, based on these specs, it looks like the GPU market is going to become a stomping ground between the two companies again - and we haven't seen that in all it's glory since ATI rolled out the X1900/50 series.
Did AMD's marketing make any claims like that? Reading the original article I see, "while the 4870 will be the first mass-production GPU with a clock speed higher than 1 GHz. Prototype RV770 boards were clocked at about 1.05 GHz." Right off the bat the reference to prototypes should be a bit of a redflag for anyone looking to take that claim to heart. Especially when he referred to final clocks (albeit in reference to the 4850) not being specified in the previous sentence. It sounds like buddy @ tgdaily might have heard the prototypes were clocked at 1.05 GHz, realized the benchmark that sets and ran with that.
I could see your point if this was something that came directly from AMD, and if they did I'll go find a crow and some salt, but I was under the impression that AMD has overall been pretty damn tight lipped (this new article seems to echo that) about these new cards and reading that article I'm not seeing any reason to think that the info came direct from AMD. The only "from AMD" thing reported there seems to be that they'd be rolling out a significant number of products in May, and even among that it goes on to say "sources now confirmed that the introductions will include desktop ... graphics parts." which points towards Dirk not specifying that. "We'll be releasing a product in May... I won't say what it is but it will be first mass-production GPU with a clock speed higher than 1 GHz" doesn't sound quite right heh...
Likewise, I'm not sure I'd place stock into leaked specs (actually it's kind of funny, if I remember correctly when leaked specs of the 9000 series were posted I could have swore you argued against their validity), especially from a source that seems to contradict itself within a weeks time. Stuff like this should be an indicition of where things are headed but I wouldn't assume leaked specs to be 100% for any upcoming products from any company.
EDIT: Its all bullshit:
www.hardware-infos.com/news.php?news=2008
See this? This is "their sources" Its evidently not from AMD Moreover, see what fudzilla says about the source:www.fudzilla.com/index.php?option=com_content&task=view&id=6994&Itemid=1
Note, fudzilla seem to be NEVER wrong. They are always correct and them actually going that that info is bull says a lot. Which means this news article is to be taken with a grain of salt...
512bit mem bus anyone?
