AMD ATI Chips Comparison Table

Main Specs

With more and more graphics chips being released every day, it became very complicated for the user who does not follow the video card market to know the differences among all AMD (ATI) graphic chips on the market today. To facilitate knowing and understanding the differences among major AMD (ATI) chips, we have compiled the following table.

It is important to note that beginning in 2007, both AMD (ATI) and NVIDIA started referring to the memory clock of their video cards with the real clock rate used. In the past, manufacturers referred to the memory clocks with double their real clock rate, because DDR and subsequent technologies (DDR2, GDDR3, etc.) allow the memory chip to transfer two data per clock cycle. So, a video card with a memory chip running at 500 MHz would be referred to as having a 1 GHz memory. We are still referring the memory clocks with the DDR naming convention – i.e., double the real clock rate – on cards with memories based on DDR or subsequent technologies.

In 2010, AMD, which bought ATI in 2006, stopped using the brand, ATI.

† From the Radeon HD 3450 on, the video card is based on the PCI Express 2.0 connection, which doubles the available I/O bandwidth from 2.5 GB/s to 5 GB/s if a PCI Express 2.0 x16 slot is used.

†† Based on the PCI Express 3.0 connection, which increases the available I/O bandwidth to 8 GB/s if a motherboard or CPU with a PCI Express 3.0 controller is used.

* AMD/ATI doesn't set a default memory clock for this video card; the specs depend on the video card manufacturer. So, you must be careful when comparing video cards using this chip.

** This video card uses two graphics processors in parallel (CrossFireX mode). The specs published are for just one of the chips.

On video cards from Radeon HD 2400 and HD 2600 series, the video card manufacturer can use a different clock for the memory (usually lower, thus achieving a lower performance compared to the reference model); the clock rates published here are the official ones.

As for the DirectX version, check the table below:

8.1	1.4
9.0	2.0
9.0c	3.0
10	4.0
10.1	4.1
11	5.0
