The pixel shaders are divided into вЂњquads,вЂќ as they are in most modern graphics architectures (this leads to greater cache efficiency). Not included on the graph is the X1300 HyperMemory part-this is a really low-cost (about $79) version of the X1300 that includes 32MB of 1GHz memory and uses PCIe access to main system memory to operate like a 128MB graphics card, albeit sacrificing some performance. If you want the top-dog X1800 XT, you need to wait a month. The two low-end X1300 models and the X1800 XL are the only ones you can go buy. But look closer: Only three of those six cards are shipping now. ThatвЂ™s actually a lot to digest, and in a way itвЂ™s very impressive that ATI is unveiling an entire lineup of graphics cards on the same day. HereвЂ™s a list of the various products, some broad technical details, their estimated prices, and ship dates:

The Radeon X1000 series, as itвЂ™s known, features a top-to-bottom line of products from $99 to $549, though not every single SKU is shipping today.

Now that R520 is finally here, how does it stack up? WhatвЂ™s so special about the new architecture? Read on as we take you through the most dramatic change in PC graphics architectures in a very long time.Дelaying the R520 has had the negative effect of giving archrival Nvidia a big head start, but it also gave ATI the opportunity to launch an entire family of graphics products at once. This unfortunate error gave Nvidia a big head start, and an opportunity to compete with ATIвЂ™s new graphics products by driving down prices.

After several chip revisions, the design bug was finally found and fixed, and in the next revision the clock speed shot up well over 100MHz.

This circuit was repeated many times throughout the chip, and when the R520 came back from the fabrication plant and wouldnвЂ™t run up to full speed, ATI struggled to figure out why. A tiny flaw in a small circuit-a few transistors out of hundreds of millions-held things up. The truth is, it was a simple circuit bug. Others said the new architecture was just a dud, a вЂњbetter in theory than in practiceвЂќ design much like the GeForce FX. Conspiracy theorists claimed that the companyвЂ™s design work to make chips using a 90nm process was the problem. What was the hold-up? HavenвЂ™t we been hearing rumblings about ATIвЂ™s R520 chip for half a year? The truth is, ATIвЂ™s new high-end PC graphics was supposed to ship in the May/June timeframe, but the chip wasnвЂ™t working quite right.
