Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It’s worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card’s memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering — AF). It is measured in millions of texels applied in one second.

Zotac GeForce GTS250 AMP! Edition, Cont’d
Zotac’s card also has the standard dual-DVI output setup, along with an S-video output. HDMI and VGA are options with included adapters, but a component video adapter is missing.
Now, let’s look at the stock clock speeds. While the core clock speed is technically overclocked from the reference speed of 738 MHz, it’s only overclocked by 12 MHz. The shader overclock is a little more inspiring with 54 MHz over the reference 1,836 MHz, for a total of 1,890 MHz. The memory is also pushed 50 MHz over reference to 1,150 MHz (2,300 MHz DDR).
In keeping with Zotac’s simple formula, it has included the most basic overclocking utility I’ve ever seen: its Firestorm overclocking software. This, ladies and gentlemen, is a good thing, because at the end of the day an overclocking tool’s purpose is to raise the clock speeds. It doesn’t need to be semi-transparent, it doesn’t need to look like it came from the year 2050. It just needs to work. And this one does.
The core overclock we achieved was typical for a GTS 250. We made it to 812 MHz on the core, and the shader clock was upped a little to 1,930 MHz. The memory made it to 1,219 MHz, for an effective 2,438 MHz data rate.
