Computer CPU Selector

Buying a computer; be it a desktop or a laptop, can be challenging. Apart from the obvious factors such as Look & Feel, Size, Weight, Price, Freebies, there’s the confusion about what is the performance of the CPU we are buying and how does it stack up against the computer that we know we cannot afford.

Fortunately, CPUs from Intel, AMD and VIA are regularly bench-marked by a common industry software called ‘PassMark’. PassMark CPU scores are now commonly accepted and published by technology sites.

While PassMark scores (Available here) are organized beautifully into categories, I wish it was available in a spreadsheet format which I could download, manipulate and print as per my requirement.

So here it is, a Google Spreadsheet that lists all the CPUs listed on CPU Benchmark, with the respective PassMark scores. Please note that this document is current as on 31-Aug-2012. The document may/may not be updated by me.

Click here if you want to open the spreadsheet in a new browser window. You can download the spreadsheet in different formats to your computer. The options are available in the ‘File’ menu.

A final word of advice: Apart from the raw computational power of the CPU, other factors that make a significant difference in the day-to-day performance of your computer are:

  • RAM: Minimum 4GB RAM is recommended for Windows 7/Vista (64-bit OS). Maximum 3GB RAM is recommended for computers using 32-bit OS.
  • HDD: Faster Solid State Drives (SSD) are recommended for Windows 7/Vista. If not SSD, HDDs with 7200 RPM spindle speed deliver better performance than HDDs with 5400 RPM spindle speed.

Other factors to consider are:

  • Screen size & quality: Go for a screen size that makes for comfortable display and reduces the need to squint. Also check for glare (reflection of lights on the screen) which is a common issue with glossy screens. Check the horizontal and vertical viewing angles. Most budget laptops feature screens that drastically change colors/brightness if you view the screen at an angle.
  • Keyboard & Touchpad quality: Ensure that the keyboard is comfortable to type on and the keys you use frequently are of appropriate size. Check if the touchpad tracks your finger movement smoothly and if it can handle accidental brushing of the touchpad with your palm (Palm Check).
  • If you are likely use the laptop for audio-video conferencing, check the quality of video from the webcam in dim lighting conditions. Also check if the laptop accepts the pins of a headset.

Happy shopping!

  1. Hello,
    Rajib I play a lot of games and mostly the latest ones, and I would like to play them with all my friends. And to do that these games are asking me to port forward, then again i browsed internet learned to edit registry tried to forward port but was unsuccesfull. And tried a lot, watched a lot of tutorials too but no results. The again we can join in other people’s games from our games, and later when we host a game nobody can join in these games. We all are having Beam Telecom Internet Connections-1 mbps which is enough for our gaming needs, and pretty good pc rig’s with latest graphic cards too all running mostly windows-7 Ultimate and Windows 8 Release Preview. If any possibility of contacting please let us know, my e-mail:[email protected]!!!!!!!!!

    • Dear Savi,

      If the Beam cable wire is directly connected to your computer, then you need not do any port forwarding. Port forwarding should be done on a router (if you are using a router to distribute the beam internet throughout the house).

      More often than not, it is Windows Firewall / Antivirus Firewall that blocks incoming/outgoing connections of the games and you should have a look at this first.

      To understand port forwarding better, consider this:
      – You have three computers in your home, connected to a router, which in turn is connected to your ISP.
      – Your gaming computer is running Counter Strike in Server mode and it is waiting for incoming connections from your friends.
      – You give your Internet connection’s IP address to your friends as the location of the server. You can use to determine your IP address.
      – When your friends try to connect to the IP address, they actually connect to the router. The Counter Strike clients attempt to talk over ports 27030 – 27039. Since your router does not provide any service on these ports, the client chatter is simply discarded.
      – So, you proceed with setting up port forwarding on your router. You say that any chatter received over TCP port 27030 – 27039 should be forwarded to computer with internal IP address of (assuming that it is the IP address you have assigned to your computer. Use ‘ipconfig’ to find out).
      – Now any chatter received over Counter Strike ports is not discarded by the router, it is simply forwarded to your computer for handling it. On your computer, the Counter Strike server receives these data packets and establishes gaming sessions with your friends.
