| What is a MHz ? |
| 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 valuable 220,- to 249,- USD. The X1800 GTO core you'll find on this new graphics card is running at a tact frequency of 500 MHz accompanied with it's memory running at (2x500MHz) 1 GHz. Speaking about memory, 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 ?I would not be rather shocked to see the GTO work with an XL BIOS. But I'm sure a couple of buyers will definitely try that out. It looks like this products comes from the same product 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, it 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 support for Shader Model 3.0 as it finally became important in the industry and we now see broad support for it.
Quite a sight isn't it ? The PowerColor X1800 GTO.
