This article isn't properly part of the three-part series about PC Performance Basics, Video Card Basic Information, and the abbreviated Video Card Ranking List for everyday use. It is supplemental, and the listing is split apart, where my shorter list combined generational cards into series groupings for simplicity's sake, and because that seems to be the way that game developers were listing the cards that they supported.
Multiple generational ladders
The fact is too many people still fail to consider that the numbers in video device names are not all in a single ladder. There are four separate ladders, actually. The n100 / n200 /n300 trio are almost always onboard chips and those progress up the generational ladder at the very bottom end; none of them has ever even reached the (current) Low Quality business graphics level. An HD 4200 is at the very top of its own extremely short little ladder (in case this is unclear in any way, onboard = inadequate). In the past, n300s were actual cards, and a few are cards with that number, again, more recently.
Next is the business class parts, with the rest of the n300s, n400, n500 performance numbering in the names. They are too slow and too limited for games, but are superior to onboard chips. As time passes, and the new generations arrive, the Low End does move, but much more slowly than the High End does. That 4200 IGP does equal the four year old Low End cards (7300 GT, X1300 Pro), and surpasses the five year old Low End (X300, 6200 A -- you will also note the "n200" / "n300" there. The IGPs then weren't anywhere close to Low End four years ago, and "Low End" was a bit broader). nVIDIA's G210 is a business card. These cards were never meant for games, although current ones can usually handle the older games from five years ago or so.
A Mainline Gaming card has an "n600" in its name and a Medium sized ladder. These cards do improve somewhat more each generational "year" than is true for Low End Cards; some years there are also "n700" cards that sit up near the border between Medium and High End. The better Mainline cards tend to stay just about two generations behind the High End cards' baseline performance, but with a reduced screen resolution capability due to a narrower memory bandwidth.
The Geforce GT 220 is near the bottom of Mainline, the Geforce GT 230 and GT 240 are somewhat above the 220, and the Geforce GT 250 is on the borderline between Mainline and High End.
The tallest ladder belongs to the High End cards, which can leap up several rungs at a time some years. They have an "n800" or "n900" performance code in their names, or in the case of the Geforce 200s, a GTX60, GTX75, GTX80, etc. It is only when we are dealing with these most expensive, fastest cards, that the "newness" of one compared against another means anything.
In the listing that follows, you will see that the different generations' members scatter out and are intermixed. Just because a card is "new" simply has no real meaning.
I will add a more lengthy version of the video card rankings lists that hasn't been simplified / compressed at the high end to make the list shorter.
Continued, Next Message.
