Memory Clock & Core Clock

[Zephik]

First off, what does those two terms mean to me? Second, What is better? High frequencies or Low frequencies? I was looking through graphics cards and only just now started to wonder about them. ...I'm slow, get over it lol

The core clock is how fast the GPU (Graphics Processing Unit) runs. The memory clock specifies how fast the memory runs and are the most important things when telling the performance of a graphics card. The memory type usually, DDR2 or GDDR3 are the most common, DDR2 memory is used in many low and middle end cards. GDDR3 is faster and more power efficient and can be found in some middle end but is mostly found in high-end cards. The memory interface is usually either 128-bit or 256-bit in the realm of graphics cards, this is how much data that can be pushed through the memory at any given time. 256-bit is better and will usually only be found on high-end graphic cards. The forthcoming nVidia 8 series is supposed to use GDDR4 memory which was just developed by Samsung, it will cut power usage by 40% and increase performance.

Hope this answer is what you're looking for.

That quote from Yahoo is a bit old. The nVidia 8 series already came out and they use GDDR3.

You want higher frequencies (you might be confusing this with latency).

Here are some good beginner guides from Tom's Hardware if you want to learn more:

if you wanna read less, think of it like this: latency is a measurement of delay and mhz is a measurement of speed. you want no delay, and top speed, but you settle for what they sell ya ^_^
