Socket 478 Celeron 2.6GHz CPU
Understanding the markings on a CPU can make the difference between buying a CPU that’s optimal for your motherboard or buying one that’s slower. Even among CPU’s rated at the same clock speed there can be large differences.
The 2.6GHz CPU pictured here is a good example of a CPU that at first glance appears snappy, but is slower when compared to other CPUs.
The first indication this CPU is slower than others is the Celeron marking. Wikipedia describes Celeron CPU’s in this way:
Celeron processors can run all IA-32 computer programs, but their performance is often significantly lower when compared to similar CPUs with higher-priced Intel CPU brands.
Right after the 2.60GHz marking is the CPU’s level 2 cache, in this case 128kb. The cache controls how much information is being passed between the RAM and CPU. A 128kb cache is a very small amount of bandwidth. Consider that a Intel Pentium G620 Dual-Core Socket LGA1155 CPU has 512MB Level 2 cache and a Level 3 cache of 3MB, 128MB of L2 cache is minuscule (there is no level 3 cache on the CPU pictured).
The next number beside the cache, the 400, is the bus speed. If your motherboard only supports a front side bus speed of 400MHz then this CPU might suit your needs. But even among Socket 478 motherboards many support faster bus speeds ranging from 533 to 800MHz. If you own a Socket 478 motherboard with an 800MHz bus speed it’s better to opt for a CPU with an 800MHz bus speed.
The model of the CPU is next, SL6W5. Google SL6W5 and lots of web sites chock full of information for the CPU comes up.
This is most of the information you really need to know looking at CPUs. Most chips since early Athlon list at least clock speed, level 2 cache size and bus speed, but if you don’t see any of these you might want to check those “other numbers” on CPU archival sites like cpu-world.
Just a quick note that I have added a new link to the web site with a list of movies we own. The meta-data is not all correct because I used imdb lookups to determine much of the information.For example, some movies have more than 1 DVD or Blueray, but I’ve just indicated 1. Despite looking very nice and having a lot of movies, IMDB actually isn’t that fantastic when it comes to DVD information lookups (scraping). I found DVDEmpire to be a better resource, but only found this over 100 movies in to my collection lookups. More on DVDEmpire and the process in another post.
I’m not terribly fond of the template and will likely change it, but for now it’s a good start.
Yes there’s no telling for taste in movies. Some of these guys were so cheap that I just bought them for something to watch. Now that my time is a lot less I’m not watching as many movies.
This list is really for family and close friends, but feel free to comment (here) otherwise. The movie list isn’t integrated well into the web site, but it might be possible to make the pages behave better.
