A Guru3D fact
One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. For example, a graphics processor that runs at 600 MHz executes 600 million cycles per second. Each computer instruction requires a fixed number of cycles, so the clock speed determines how many instructions per second that processor can execute.

Well my friends, let's get this article started, as usual .. in-depth.

The Radeon X1800 GTO is of course a product of the latest X1000 family of ATI GPUs. The X1800 GTO series is priced at a rather affordable 189 USD. The reference X1800 GTO core you'll find on this new graphics card is running at a tact frequency of 500 MHz accompanied by it's memory running at (2x500MHz) 1 GHz. You'll notice that HiS has overclocked the card a teeny weeny bit for you at default towards 520 MHz on the core.

$ffffffffff ATI specific display adapter information
$ffffffffff ----------------------------------------------------------------
$0900000000 Graphics core : R520 (12tmu)
$0900000002 Memory bus : 256-bit
$0900000001 Memory type : DDR3 SGRAM
$0900000003 Memory amount : 256MB
$0900000004 Core clock : 519.750MHz
$0900000005 Memory clock : 495.000MHz (990.000MHz effective)
$0900000006 Reference clock : 27.000MHz

Memory then, it's GDDR3 memory and there's 256MB of it. Do you recognize the X1800 XT specifications already? More significantly .. do you recognize the X1800 XL already ? Correct, it's the exact same core. So I would not be rather shocked to see the GTO work with an XL BIOS, and I'm sure a couple of buyers will definitely try that out as it looks like this product comes from the same line. So yeah .. correct .. it's the same chip yet is has less pixel pipelines active. The product is equipped with 256MB 256-bit memory, is armed with eight Vertex processors and furthermore utilizes the entire feature set that the entire X1000 family of products entail.

Some miscellaneous features:

  • Ultrathreaded Architecture with fast dynamic branching
  • 12 Pixel Shader Processors
  • 8 Vertex Shader Processors
  • 512-bit ring-bus memory controller
  • 256-bit memory interface
  • DX9 Shader Model 3.0 support
  • Simultaneous support for HDR and Anti-aliasing
  • Avivo video & display feature set
  • H.264 playback acceleration
  • Two dual-link DVI outputs
  • Full 10-bit display processing & output capability
  • CrossFire support
  • Single-slot PCI Express board configuration

Alright, let me commence the usual blurbs.

The GTO of course has super duper support for Shader Model 3.0 as it finally became important in the industry and we now see broad support for it.
