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:

If there are 1,000 people, with 71% being Nv users - that means 710 of them are Nvidia, and the rest are divided between SiS, Intel, S3, and ATI.
lets say half of them crashed (dead split, 50% of that entire group) - funnily enough, more of the crashes will be caused by nvidia since there ARE MORE NVIDIA SYSTEMS TO CRASH.
WHY cant you get that? jesus...
AND if I remember crrectly intel has less crashes than either nvidia or ati. the article basically praised intel onboard drivers. as well as intel chipset drivers (as the article never stated that they polled users with addon graphics only) meaning that nvidia chipsets and amd/ati chipsets are in there as well.
Basically ALL of you read the article wrong. and somehow you're all thinking that the article was on add on graphics only, quite funny as intel DOESN"T SELL ADD ON GRAPHICS and was included.
90% of the computer users on vista have onboard graphics, meaning that it has as much to do with chipset drivers as it does vga drivers. seriously get off that article because all it is is Microshaft blaming everyone else for it's own mistakes.
Anyway 512bit and gddr5? that means a lot of bandwith. What for? Gddr3 is cheaper, 0.8 gddr3 with 512bit memory interface would make some sense, but very fast ram AND 512 bit make no sense at all.
But it would be really a surprise if we would get a cheap card with (1gb) gddr5 and 512bit :D
If we HAVE to talk about Vista crashes and Nvidia drivers in a thread about new HD4000 cards, at least let's do it with real numbers. Here you have actual market share figures:
www.xbitlabs.com/news/video/display/20080403230057_ATI_Begins_to_Fight_Back_Market_Share_from_Intel_Nvidia_JPR.html
Here's a resume: Intel's average for the year is around 40%, ~30% for Nvidia and ~19% for Ati.
Now I have to say that I agree a bit with newtekie. Even though he is using bloated numbers, what he said has sense. You have to take into account that most Intel IGP users are not doing anything stressful enough to get a crash related to graphics. The chances for Office, Mozilla or Emule to cause graphics related crashes are not very high, mefinks. Anyone with more "ambitious" needs will use a discrete card, even if it's only for watching movies on the PC, or they will use Ati/Nvidia integrated graphics instead of Intel IGP.
You can't use bold numbers in this situation since the use that people give to their machines is most relevant than the graphics adapter itself. Overclocking, driver changes, hardcore gaming, benchmarking/stressing the card, all of them are risk factors that could eventually lead to crashes. None of them are going to happen in an Intel IGP.
I would apply the same about Vista. Amongst people using Vista there's a bigger chance to find Ati/Nvidia discrete cards than on XP machines. The last time I heard a Vista and graphics card related news (aside the Vista crashes one), it was about Vista increasing the number of discrete graphic cards sold.
Those two facts take Intel out of the ecuation IMO. So that leaves us with Ati vs. Nvidia crash numbers. Here Nvidia has ~66% of market share, but there were reports that Nvidia was selling way more DX10 high-end cards (before RV670, but a year selling "only" Nvidia 8 series leads to lot of users), while Ati was selling more low-end and integrated graphics. If you look at the charts, you can see that Nvidia+Ati sold 52 millions of graphics adapters in Q4 2007 and in the next link we can see they sold 31 million discrete graphics on the same timeframe:
www.xbitlabs.com/news/video/display/20080404234228_Shipments_of_Discrete_Graphics_Cards_on_the_Rise_but_Prices_Down_Jon_Peddie_Research.html
Almost half of the cards are integrated, where Ati was selling more. Again there's a low risk factor between people using integrated graphics. We can easily conclude then that between the risk factor crowd the number of Nvidia cards is a lot bigger than what pure market share would suggest.
In the end what I mean is that Nvidia causing more crashes is purely stadistics at work and has nothing to do with driver quality. None of te companies offer better drivers than the other.
The specs here are from the exact same source as the claim that the 4870 was going to be the first mass produced GPU to run at 1GHz(TG Daily), and they are probably just as full of BS.

About the crashes in Vista:
The numbers MS released are only related to the amount of crashes Vista had when Vista was released. So that's only Q1 2007 maybe Q2 too.
These are the numbers:
Rank Graphics Supplier Q1'07 Market Share - Q4'06 Market Share
1 Intel 38.7% - 37.4%
2 Nvidia 28.5% - 28.5%
3 AMD 21.9% - 23.0%
4 VIA Technologies 6.4% - 6.7%
5 Silicon Integrated Systems (SiS) 4.3% - 4.5%
6 Others <1% <1%
So claiming there where 2x more nVidia cards in that period and that's why there are 2x more crashes is ridiculous. Even ATI is not too far off nVidia. ATI's market share used to be bigger in the previous quarters. Some of those people upgraded too to Vista. So as i said, the statement that there are much more nVidia cards can't stand. I have first hand experience with the initial Vista drivers for 8800GTX. U really didn't have to go into a game to experience crashes. It could even crash or blue screen because of Aero or standby. So you shouldn't divide up IGP and discrete GPU's.
why don't we all wait till a reliable spec or a bench show up
it's a waist of time reading all the posts...fans from both sides arguing for nothing
I think the 4xxx series will be great. Certainly a lot better than the 3xxx series, esp. with DOUBLE the texture units. That is a bottleneck solved. So heres to the benchmarks :-) :toast:
HD.3870.3Dmark06=12,590 vs. HD.4870.3Dmark06benchmark.leak.html=21,223 :D
Thanks
Intel graphics is just handed out, pretty much free, as part of the transaction when buying an Intel based PC.
I think we will be back to AMD at the mid-range and NV at the top in no time. This chip isn't going to really blow past the current top stuff, even in CF. And NV certainly isn't just sending its engineers to posh parties and skipping out on R&D for a new GPU.
