Truth about Videocards/GPUs

Ex. AMD Radeon HD 677/ Nvidia GeForce GTX 780

  • The first digit is the generation (2nd Important)
  • The second digit is the performance indicator (Very Important)
  • The third digit is a refined performance indicator (Least Important)
  • The forth digit is often just 0


Performance indicator numbers: 
(red number)
1: Intergrated graphics product, very low performance
2: Low performance
4-3: Low-Mid performance
5-6: Midrange performance
7-8: High performance
9: Ultra High performance

Examples:
High Performance ang AMD Radeon HD 6770 at Nvidia Geforce GTX 770.
Low-Mid Performance ang AMD Radeon 6470 at Nvidia Geforce 530

So when it comes to performance. the higher the second number the better.
So AMD HD 5000 series… 5450<5550<5570<5670<5750<5770<5830…
if combined AMD HD 4000 series… 4350<5450=4550<5550<5570=4670<5670<575…

not only memory is important to look at you also need to check other like:
(red as the most importantand green as second most important.)

Architecture
Pipelines
Pixel/Vertex Shaders
Core Speed (here you could know if you could overclock it. Nvidia has base boost feature)
Shader Speed
Memory Speed
Memory Bus Width ( 64bit/128bit/256bit etc.)
Memory Type (GDDR5/4/3)
Memory Size (ng GPU) (here we usually look at which we should not.  the 2GB 1GB…)
Technology
Power Consumption
DirectX Support (11 up)
OpenGL Support
Physx Support ( Nvidia only)

The Popular Axxo Secrets on how to RIP DVD

Ripping a DVD to xvid or divx avi is really quite easy, if you have the right tools. You’ll first need to download DVD decrypter and auto gordian knot (autogk). DVD decrypter allows you to rip the raw DVD video and audio data off of your disk drive, decrypt the CSS protection, and finally remove any other protection schemes, such as Macrovision. AutoGK is a package of codecs and a GUI interface that will take the raw DVD data through an AV processing pipeline to produce a single windows video file.

Step 1: RIP

Put in a DVD and launch DVD Decrypter. Choose IFO (Information File) mode:
( Figure 1 )

Now make sure you’ve selected a destination for your files:
( Figure 2 )

Now you need to find which program chain to rip (PGC). Pick the one that’s the longest, or in the case of a TV dvd, the episode you want to rip:
( Figure 3 )

Everything’s set up. Just click the green arrow and wait about twenty minutes, after which you will have a set of files which look like this:

VTS_01_0.IFO
VTS_01_PGC_07 – Stream Information.txt
VTS_01_PGC_07_1.VOB

The whole ripping process shouldn’t take more than 5 minutes.

Step 2: ENCODE

Launch AutoGK and select the first .vob that you just ripped as an input file, and set an output file name:
( Figure 4 )

Now you need to select audio (choose the first one) and subtitles, if any:
( Figure 5 )

If you’re ripping a TV, set the preferred size to 350MB, if you’re ripping a movie, choose either 700MB or 1400MB, depending on your preference:
( Figure 7 )

Finally, click on advanced settings and choose MP3 VBR 128kbs:
( Figure 8 )

Then click “add job” and “start.” After all this, you’ll have a log that looks like the following:
