ATI's Late Response to G70 - Radeon X1800, X1600 and X1300

Feature Overview
There are quite a few exciting new features being introduced with ATI's new X1000 series. Of course, we have a new line of hardware based on a more refined architecture. But at the end of the day, it's not the way that a company implements a dot product or manages memory latency that sells product; it's what consumers can do with the hardware that counts. ATI will not disappoint with the number of new features thtat they have included in their new top to bottom family of graphics hardware.
To provide a quick overview of the new lineup from ATI, here are the key featuers of the X1000 series.
Running on a 90nm TSMC process has given ATI the ability to push clock speeds quite high. With die sizes small and transistor counts high, ATI is able to pack a lot of performance in their new architecture. As the feature list indicates, ATI hasn't just waited idly by. But the real measure of what will be enough to put ATI back on top will be how much performance customers get for their money. To start answering that question, we first need to look at the parts launching and their prices.
Along with all these features, CrossFire cards for the new X1000 series will be following in a few months. While we don't have anything to test, we can expect quite a few improvements from the next generation of ATI's multi-GPU solution. First and foremost, master cards will include a dual-link TMDS receiver to allow resolutions greater than 1600x1200 to run. This alone will make CrossFire on the X1000 series infinitely more useful than the current incarnation. We can also expect a better compositing engine built on a faster/larger FPGA. We look forward to checking out ATI's first viable multi-GPU solution as soon as it becomes available to us.
Rather than include AVIVO coverage in this article, we have published a separate article on ATI's X1000 series display hardware. The high points are a 10-bit gamma engine, H.264 accelerated decoding and hardware assisted transcoding. While we won't see transcoding support until the end of the year, we have H.264 decode support today. For more details, please check out our Avivo image quality comparison and technology overview.

- Fabbed on TSMC's 90nm process
- Shader Model 3.0 support
- Fulltime/fullspeed fp32 processing for floating point pixel formats
- New "Ring Bus" memory architecture with support for GDDR4
- Antialiasing supported on MRT and fp16 output
- High quality angle independent Anisotropic Filtering
- AVIVO and advanced decode/encode support

Where is the AA info and AF info on each test?You list 4x AA for the High End cards at 1600x1200. What about other levels of AA, and various levels of AF?
What about other resolutions? and varying levels of AA and AF at different resolutions and how they compare image quality wise? Okay, so the X1600XT loses at 1280x960 with no aa or af. What about at 1028x764 with AA and AF on? And how does that compare image wise?
Where is the discussion of the results? You just throw out graphs at me, and don't do a real disucssion of them.
In otherwords, where is the rest of the review?
Peldor - Wednesday, October 5, 2005 - link
At this point, a fairly weak review from Anandtech, especially compared to the 7800GTX review when it appeared. Hot Hardware and Tech Report have a bit better coverage IMO.Looking at other reviews around the web, my conclusion is the X1800 cards are viable competitors in performance to the 7800 cards, but the street prices will have to come down near the 7800 cards to be a good value.
The X1600 cards look dead in the water when the 6600GT is under $150 and available in AGP and PCIe, while the 6800GT is far beyond it in the ~$250 segment.
The X1300 cards will only survive in the ~$100 and under market.
ATI is going to need that R580 sooner rather than later.

The format of the hardocp articles has grown on me, especially after reading there review + the anandtech + another.There are all kinds of AA and AF options for a reason. They look different. How do the affect peformance though? What works best?
That obviously varies by game, card and resolution. But anandtech and others just don't do the comparisons and I think that makes it difficult to compare. Especially when image quality differences between nvidia and ATI come into play with there various settings.

We will have tables of all the data with all the numbers we ran across all the resolutions with 4xAA and 8xAF up shortly.Quite a bit of data was collected and it has taken some time to organize. You are absolutely right to want more, and we are working on getting it out the door as soon as possible.
Thanks,
Derek Wilson

Derek,You really need to evaluate your situation at this website. You are listed as "author" of the "NVIDIA's GeForce 7800 GTX Hits The Ground Running" and "ATI's Late Response to G70 - Radeon X1800, X1600 and X1300" articles. Both of these articles are not up to Anandtech standards and have prompted numerous posts for readers to visit other websites.
I am a long-time reader of the site and am only posting this because I don't want to go anywhere else. I just don't believe that your articles have been up to snuff. The posts for proofreading, wrong labels, incomplete data, etc keep appearing and back up my opinion.
If Anand did not finish your mentoring, please let him know. I know that you put a lot of time and effort into this site, but the two biggest articles of the year for GPU's have left me shaking my head in dissapointment. Please work more with Anand, or do your own homework and read some of his old reviews. If you need another person, or co-author to help you ...please swallow your pride and ask for it.
Respectfully,
Jeffrey

What credentials do you have to make such an accusation? What indicators do you use to support such a statement? On the contrary, considering the time frame and the rush to provide us with information it is obvious for the coherent, that he has done a good job. Glad to see information provided that will futher support my next video card selection.erinlegault - Thursday, October 6, 2005 - link
That is exactly the point! He shouldn't be rushing. The Techreport and Xbit Labs and many others offer much more informative reviews.Do you want my credentials? It shouldn't matter a report is a report is a report. You don't have to have a PhD or be a CEO to have an opinion. Any person with a University or College degree knows how to write a report that is complete and accurate.
The fact of the matter is Anand's graphics reviews have been not up to par. Period.

lol.. the 'fact' is that this 'opinion' isn't up to 'my standards'sounds like a real fact, folks.. this guy is serios business

I absolutly hate obvious marketing fluff!"16 ultra efficient extreme pipelines"
Those pipelines are about as extreme as a peanut butter and jelly sandwich is extreme. Try harder next time Ati!
