3Digest: April 2007


Monthly drivers report and popular 3D
accelerators comparison

Monthy 3Digest is the project of iXBT.com and Digit-Life.com dedicated to informing you about the performance of a large number of graphics cards under Windows XP in the past month.

This issue is dedicated drivers released from the 15th of March 2007 to the 15th of April 2007. Traditionally our 3Digest informs you about the best price/performance ratios available in the market. Another very important part of any 3Digest is cards' 3D graphics quality shown on the example of a wide selection of games.

It's our 83th issue of 3Digest.

April 2007

We have added test results for GeForce 8800 GTS 320MB, GeForce 8600 GTS, GeForce 8800 Ultra, and overclocked GeForce 8800 GTX.

Attention! This digest contains benchmarking results for PCI-E cards only! The final AGP benchmarking was conducted in March 2006!

Archive (videocards, information on which is no longer updated)

3. April 2007 news and matters

Added a number of new graphics cards (marked "NEW").

4. Summary charts of graphics card performance with the latest drivers available at the moment of testing in April 2007

All willing to see the complete results in Excel 2003 format can download this RAR 3.0 or this ZIP archive.

If you are familiar with 3D graphics, you will be able to draw all the conclusions yourself after looking at the charts provided. Those interested in our judgement of test results should see reviews dedicated to specific GPUs (see our 3D graphics section). And for newbies and those who has just started choosing a graphics card we'll provide some more detailed explanations.

First of all, you should take a look at our brief references of modern graphics card series and their respective GPUs. Note clock rates, shader support and pipeline architecture.

Reference for ATI RADEON X1300-1600-1800-1900 series

Reference for NVIDIA GeForce 7300-7600-7800-7900-8800 series

Secondly, in our 3D graphics section all newbies can read about the basics of 3D (this knowledge will be required anyway, because you'll surely try to adjust some game settings: textures, lighting, etc.) Besides, newbies should read separate reviews dedicated to new products. There are just two GPU vendors: ATI (recently merged with AMD under its brand) and NVIDIA. Thus, all information is generally separated in two parts.

Thirdly, let's see the charts and make conclusions.

Attention! Due to some technical issues some test results became interchanged. Tests of GeForce 8800 GTS 320 / 640MB at 2560x1600 were conducted separately. And due to a mistake in input of numbers for SOME tests the results of 8800 GTS 320MB became interchanged with those of 8800 GTS 640MB and vice versa. We emphasize, this is ONLY about 2560x1600 and SOME tests. All other results are in their right places. We'll fix these errors next digest. Note that we've already fixed them in test result tables.
