An alleged screen capture of the ATI version of Rydermark (saved and reposted to preserve metadata)

An alleged screen capture of the NVIDIA version of Rydermark (saved and reposted to preserve metadata)

A difference map of the two images
"Rydermark developers" make bold claims which turn out to be nothing more than a Photoshop hoax

It would appear The Inquirer was quick to jump the gun on a story accusing NVIDIA of lying about full DirectX 9 support. The story accused NVIDIA of not allowing developers to use 24-bit or 32-bit shader precision. Instead it claims NVIDIA forces developers into using 16-bit shader precision as the technique is faster. This is a problem as DirectX 9 compliancy requires 24-bit shader precision or better.  "Rydermark" is not a commercially shipping application yet, and has had very little information published to confirm its authenticity.

The original story lacked any type of physical evidence and The Inquirer claimed its sources were developers for the program. Images allegedly proving that NVIDIA forces developers into using 16-bit shader precision were posted on The Inquirer. The posted images compared a rendered scene in Rydermark 2006 between ATI and NVIDIA graphics cards.

It turns out the images "proving" NVIDIA’s wrongdoings were nothing more than poorly done Photoshopped images.  The NVIDIA rendered image appeared to have blurrier water while the ATI rendered image had sharper water detail. However, the ATI rendered image just didn’t look right with poor cut offs and a creation date three minutes after the NVIDIA rendered image.  A difference image of the two JPG files can be seen to the right, with the outline of the modified  area clearly visible in the ATI image.  This would suggest the NVIDIA image was the original source image, and that the ATI version was modified afterwards.

A difference of the metadata from both images reveals that the NativeDigest delimiter is identical for both images, but has two different InstanceIDs.  This would be consistent with an image that was modified and saved twice.  In the author's defense, images that are created and saved on his computer have distinct metadata tags that are very easily identifiable.  These are not present in the two images supplied by The Inquirer for "Rydermark" -- suggesting the images may not have been modified by the author.

There’s been an outcry of The Inquirer images on various forums including Ace’s Hardware, AnandTech and Beyond3D.

Update 07/19/2006: The Inquirer has posted something resembling a rebuttal to this article. Incredibly, a user from the forums managed to track down some of the stock art used in the screen renders, and believes the entire image is actually fraudulent.

They started it out in the english speaking world though, in fact they got it out of the confines of that french site where it would probably have stayed.
That's the strength and weakness of the inq, they aren't afraid to speak out, and they don't sign NDA's, and they are the only ones that don't AFAIK.
So if you keep a grip on your senses and check the stories they bring out yourself then you have a fine site to read and feed your curiosity.

True, they dug it up, but the origin of the rumour is still x86-Secret.

I generally find The Inquirer to be very good at reporting news and rumours and not stating things as absolute fact if they don't have confirmation for it from sources. The no-NDA policy is something I applaud. A lot of people also state that The Inquirer is wrong in more cases than they are right, yet no one provides numbers or facts showing just that. (I can agree with the lack of spell checks, though, that even irks me, and my native tongue is Swedish.)

Although in this case, the look of the screenshots doesn't leave much to the imagination. It's pretty evident that there's something funny going on. Hopefully it'll be rectified as soon as possible.

X86-Secret clearly stated that the technology of "Reverse HT" is planned for K10 and considering that they were talking to an AMD engineer when they obtained that info, I would say that it's better than just a rumour. Also note that the idea behind "Reverse HT" is not new as both AMD and Intel have been talking about the possibility of this well before all those recent stories appeared - you can find a lot on it in their long-term roadmaps and their technology research section - note that "Reverse HT" or "Anti HT" are just "make-up" terms; look for speculative threading or cluster multithreading instead.

The Inquirer, OTOH, pushed the "Reverse HT" as something already found in K8 and even managed to get some estimates of the performance too. How did they do that? I wonder. This has all been proven to be false by X-bit labs and the Inquirer, themselves.

DailyTech does not sign NDAs.

So if you have access to some information through Anandtech (covered by an NDA), you can post it on Dailytech?

Didn't think so.

DailyTech and AnandTech are two separate companies. We do not share information, or anything else for that matter.
