We think this is really nasty to the customer, as customers can be easily deceived. The problem is that the reference models we got for reviewing were running at the top clock speeds and other Radeon HD 2600 and HD 2400 boards you will find at the market may be running at lower clock rates and thus achieving a lower performance. And for Radeon HD 2400 they allow the manufacturer to set any clock rate they want. The second problem is that AMD there are two basic versions of Radeon HD 2600 XT, one using GDDR4 memories running at 2.2 GHz (1.1 GHz DDR) and another using GDDR3 memories running at 1.6 GHz (800 MHz DDR). According to AMD, Radeon HD 2600 XT will reach the market 2 weeks after its paper launch, so if everything goes fine we should see this video card on the stores by the end of the next week. Unfortunately this is an old habit from ATI that AMD still couldn’t get rid off yet. All we got was a paper launch on June 28th, 2007 announcing the two families, however we are already in July and no sign of these cards on the market. During AMD’s technical sessions to present Radeon HD 2000 to the media in April, they said that Radeon HD 2600 and Radeon HD 2400 would be available in late June. There are two big problems with Radeon HD 2600 XT – and, for that matter, also with other members of the Radeon HD 2600 and HD 2400 families.įirst, it isn’t available on the market yet.

On our ATI Radeon HD 2000 Series Architecture article you can find a more in-depth explanation about this. On NVIDIA side, this unified architecture is used on GeForce 8 family – of course implemented differently inside the chip. It also means that instead of using separated shader units for each kind of shader processing (pixel, vertex, physics and geometry) video cards from this family use a unified shader architecture, where the shader engines can process any one of these tasks. What this means is that they will support the next generation of games to be released starting this year. The main difference between Radeon X1000 and the new Radeon HD 2000 families is the adoption of DirectX 10 on Radeon HD 2000 family.
Check it out.įigure 1: AMD reference model for ATI Radeon HD 2600 XT. In this review we will compare Radeon HD 2600 XT to GeForce 8600 GT and also to several other mid-range boards from both ATI and NVIDIA. Radeon HD 2600 XT is the new mid-range video card from AMD/ATI, supporting Shader 4.0 unified architecture (i.e., DirectX 10) and competing directly with GeForce 8600 GT from NVIDIA, both costing around USD 150.
