A Geek’s Post

Firstly please look at the snapshot below.

cachemem

Hmm.. Maybe to most of the people won’t understand what the heck is this about. It’s actually showing the transfer rate between the Memory, L1 and L2 Cache memory (what?)

Nah, keep it short, everyone probably know what the RAM is and the Caches are a different, faster, more expensive type of RAM resides inside/near the CPU. I upload the screenshot here just to short you how crazy the transfer rate is!

Look at the Read rate of L1 Cache: 52489 MB/s! How fast is this?

Compare to your Streamyx line of 1Mbps, the transfer rate of the L1 Cache is equal to 52489 x 8 = 419912Mbps! 400 thousand times faster than your TM Nut’s Streamxy line!

The latency is the respond time of the memory: 0.9ns. (Don’t know what is ‘ns’?) 0.9ns = 0.0000000009 seconds. Okay. Get the idea how fast it respond?

Normal home user should have around 250GB of hard disk storage, with this kind of transfer rate, the poor hard disk will be filled up in 4.8772 seconds.. If the hard disk is that fast LOL. Poor hard disk..

Yup! My Core 2 Duo E7300

Wow!!! So great!

Eek..maybe you misunderstood my means, I just want to show you the transfer rate. The rate only useful for CPU's calculations, the overall computer speed still much depend on the slowest memory such as the hard disk and RAM. Err..Don't know I'm not pro also. Ask teck siang!
