Author Topic: celeron 2.4 gig?? (Read 288 times)

as i was surfing the other day, i saw a celeron 2.4 gig processor for like 70 bucks. I have a 1.8 gig p4 on sd133 memory (400mhz bus) , so I am curious if anyone has any idea if the xtra gigahertz of a smeleron would make up for the smaller cache, ie will the 2.4 gig celeron run the game faster than a 1.8 p4?

I assume the p4 is going to be faster, but have not heard much about how the new stepped celeron runs.
thks for any info

Is your P4 a Willamette (Socket 423) or Northwood (Socket 478)? (I don't think Intel made 1.8 GHz Willamettes, but PC133 Sdram i845 boards for Socket 478 aren't that common.) The short answer is that the 2.4 Celeron would be better than a 1.8 Willamette overall, but probably no better than a 1.8 'A' type Northwood.

The Celeron processors at 1.7 GHz to 2 GHz are Willamette derived Socket 423 CPUs that offer absolutely miserable performance.

The 2.1 GHz and up Celerons are Socket 478 models derived from Northwood P4s (basically they run on a 400 MHz FSB and only have 128 kB of L2 cache). This means that best case they can offer similar performance to a 'A' type Northwood P4 (the 400 MHz FSB models), but because of the extreme reduction in cache size they usually don't perform very well compared to their P4 cousins. The reduced L2 cache size can really hurt performance in many games and other apps.

The biggest bottleneck I can see with your system is that it's using PC133 Sdram.

well, the cpu is a socket 478. I checked the cpu id using intel's cpu utility and it definitely is a 478. The system is an HP (freebie from work) that can take up to a 2.4gig, but yea the ram is the old pc133 and can't be upgraded. I don't really NEED a new cpu, but sure would love some xtra power. I fear a faster cpu may not help much due to the memory bandwidth.

Thanks for your insight

....for 100 bucks less I had to check out the new celery's. Hmm, come to think of it the new p4's with hyperthreading............

your 1.8gig P4 will thrash a 2.4gig Celeron....
