Grammar corrections desperately needed!

I just did a whole lot of grammar cleanup over at the R600 article, and now it looks like the same guy who butchered the English language over there wrote most of this article, too. The frequent references to cards that were released exclusively in China, plus the particular nature of the mistakes (most notably the frequent omissions of "a" and "the"), leads me to believe that the author was Chinese. I'm too tired to deal with this crap. Can someone take care of this, please?

RELEASE DATE

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)[reply]

--may, 2008. The link i provided is to Nordic hardware but its all over the place. Fuds got it, expreviews got it, everyones got it.

hd 4950 article

The article Hd 4850 should probably merged into here. Ant6n (talk) 19:54, 26 June 2008 (UTC)[reply]

That article now redirects to Radeon R700 -- Imperator3733 (talk) 05:11, 27 June 2008 (UTC)[reply]

IT IS RELASED !!!!=

Anyone is changing sites ?? this isn't actual state of article.... chipset has been relased (HD RADEON 3870, 3850)... —Preceding unsigned comment added by 83.25.74.8 (talk) 19:32, 6 February 2008 (UTC)[reply]

--No, the HD3XX0 series is the R600 family. The R700 chipset is unreleased. —Preceding unsigned comment added by 75.157.29.18 (talk) 07:37, 16 March 2008 (UTC)[reply]

regarding the use of ATI alias

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. --203.218.208.248 (talk) 16:04, 8 June 2008 (UTC)[reply]

Released (for real this time)

Per this article and [1]. 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 Alfador^Talk|@ 03:46, 20 June 2008 (UTC)[reply]

Yeah, this page needs updating. —Preceding unsigned comment added by 4.246.84.25 (talk) 22:31, 20 June 2008 (UTC)[reply]

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)[reply]

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. Basterisk (talk) 07:22, 21 June 2008 (UTC)[reply]

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)[reply]

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)[reply]

RV770 LE = "HD 4750"

Specs (Updated): 640 SP/32 TMU/12 ROP/256-bit GDDR3/550 MHz Core/993 MHz Memory --203.218.111.161 (talk) 11:47, 5 September 2008 (UTC)[reply]

New Pictures?

i was just thinking that we could add/improve a picture on this page.Xavier The Second (talk) 16:24, 23 December 2009 (UTC)[reply]

My Edits are Valid

ATi is ATi, AMD is AMD.

Sure, AMD acquired ATi in 2006, BUT AMD does NOT make the GPUs. ATi does. AMD is a CPU company, not a GPU one, and they merely Slapped their Logo on recent GPUs: Nothing more.

I will proceed to Correct these Pages, For I do not want False information to be shown. — Preceding unsigned comment added by 174.117.204.241 (talk) 12:18, 1 June 2011 (UTC)[reply]

And we will continue to revert it. AMD bought ATI thus AMD is designing these chips, ATI was just left as brand name. --Denniss (talk) 17:07, 1 June 2011 (UTC)[reply]

-Incorrect, ATi is Still ATi Regardless. ATi is still designing these Chips, AMD is just Slapping their Logo on recent Graphics cards: Nothing more.

As i said, ATi is ATi, AMD is AMD. Regardless of the Buyout.

I will now Edit these pages back to their true state.

Also, I wrote that ATi is a "Subsidiary of AMD". So, I acknowledged that ATi was Acquired by AMD. However, ATi is still indeed making these Graphics Card. Not AMD. — Preceding unsigned comment added by Spartanmastah (talk • contribs) 19:34, 1 June 2011 (UTC)[reply]

No, ATI is not a subsidiary of AMD, what was formerly known as ATI is now a division inside of AMD named AMD Graphics Product Group. --Denniss (talk) 20:26, 1 June 2011 (UTC)[reply]

Yes, ATi is a subisdiary of AMD. and it is only known as the AMD Graphics Product Group Internally Regardless of Name change or not, ATi: is still ATi

I will once again change it back to it's true state — Preceding unsigned comment added by Spartanmastah (talk • contribs) 20:32, 1 June 2011 (UTC)[reply]

Spite?

Are you editing these Pages out of Spite now?, I thought you were a Respectable Man.
