Talk:Radeon HD 4000 series

message: I moved a lot of stuff from Radeon HD 2000 Series and Radeon HD 3000 Series into the new article TeraScale (microarchitecture). IMO Radeon HD 4000 Series is still based on TeraScale 1 but without several of the problems it had. A couple of the problems were sorted out in the driver AMD Catalyst but a couple were changes of the microarchitecture. If you look at  and search the web a bit, TeraScale is a family of microarchitecture implementing VLIW SIMD pardigms and there were 3 major version of it. I think
* TeraScale 1 = Radeon HD 2000 Series, definitely Radeon HD 3000 Series and probably also Radeon HD 4000 Series
* TeraScale 2 = Evergreen in Radeon HD 5000 Series
* TeraScale 3 = Nothern Island VLIW4 in some of the Radeon HD 6000 Series
Then TeraScale-family was replaced by the microarchitecture named Graphics Core Next. For Nvidia there also are articles: Tesla, Fermi, Kepler
and Maxwell. User:ScotXWt@lk 13:16, 6 July 2014 (UTC)

message: The article mentions R700 is meant to be released for 45nm, in 2009. But right in the begining states that will be out in 2008. Which one is true? Daniel de França (talk) 14:33, 28 January 2008 (UTC)

thread_title: IT IS RELASED !!!!=

message: Please note that ATI is no longer a company after the acquision by AMD Inc., instead it's now only a brand name instead of an individual entity.
The people who are doing the Radeon line is now belonged to a group in AMD, the AMD Graphics Product Group.
While it is a subsidiary in nature, the use of ATI alias is now only limited to product branding only. For example, the ATI Radeon Graphics Processors, the ATI CrossFire Xpress 3200 chipset for Intel processors, the ATI XGP Technology, the ATI CrossFire X technology and so on.

message: Per this article and .  I don't have the time to go through it all now but if no one gets info together in a day or two I'll take a crack at it.  I am for one quite curious to see the benchmarks on this card since it is only priced at $199 US.--Oni Ookami AlfadorTalk|@ 03:46, 20 June 2008 (UTC)
replies: text: The above information you've mentioned is about the "technical previews" of the Radeon HD 4850 products, and is not related in any way to the official release of such products. The official release date for Radeon HD 4850 product is June 25, 2008. While for the Radeon HD 4870 product, the release date is slated for July 8, 2008, there is no change to the official launch date. Thank you. --218.102.110.135 (talk) 03:21, 21 June 2008 (UTC)
replies: text: The 4850 appears to be for sale(not reserve) at every online electronics retailer that I've checked(Newegg, TigerDirect, ZipZoomfly).  I cannot verify though that the 4850 is in any stores yet, as I have not checked, but I would think that if at least TigerDirect is selling them on their website, then they are selling them at their outlet stores.

replies: text: In Hong Kong, they are in stores, even the Radeon HD 4870 products. But does that mean AMD has released them? No, I don't think so. --218.102.110.135 (talk) 14:45, 21 June 2008 (UTC)
replies: text: Regardless of whether the 4850s were officially released or not, this page is still based almost entirely on rumors and tech tabloids, and it should be updated. 67.173.76.220 (talk) 19:20, 21 June 2008 (UTC)

thread_title:  External links modified 

message: As of 4/1/2018 the paragraph "GPU interconnect enhancements" found at the end of the Architecture section has two (2) egregious lapses of editorial competence:
"Current generation of dual-GPU design also features an interconnect for inter-GPU communications through the implementation of a CrossFire X SidePort on each GPU, giving extra 5 GB/s full-duplex inter-GPU bandwidth. These two features increase total bandwidth for dual-GPU designs to 21.8 GB/s. At this point, the CrossFire X sideport interconnect has never been enabled in any available drivers."
It should go without saying that it is extremely poor practice to assume that the word "current" and the phrase "at this point" MEANS anything to the reader who may be reading this in 2018, 2020, or 2040. It is totally inappropriate and does not belong in an on-line encyclopedia article.
If someone wants to check back in the editing history (or happens to know (and have references for) the date at which these two statements were correct, then the paragraph should be edited to indicate that.  I am going to remove, unilaterally, the sentence starting with "At this point" and change "Current generation..." to "Subsequent generations..." although this is awkward construction, it doesn't make the gross blunder of assuming that things don't or haven't changed over the last 10+ years (and who knows how far into the future?).174.130.55.77 (talk) 22:42, 1 April 2018 (UTC)
