I have a intel cel.-D 3.2 ghz/ 533 mhzFSB/512 kb L2Cache. I am on a limited budget, but I need a little more CPU speed. Any suggestions?

CPU's of different designs can not be compared with Ghz ratings. After all a 2.2 Ghz Athlon 64 was faster then a 3.0Ghz P4. I7 is far faster per clock then anything on the market(More or less).

Do you know what board you have? If it is a LGA 775 with a new enough chipset and power system, it can run a core2 duo/quad. Those work destroy a Celeron 351(if that is what you have).

You can get allot of info on your cpu and board from CPU-z

As much info as you have on the system will help....

As far as CPU's go your Celeron D is slower than almost every current generation of processor. I would say as long as you don't upgrade to a Atom or AMD E series your CPU will be a lot faster than what you have right now.

To help you pick what is best for your budget it would be better if we knew where you are from (Country), what your budget is, and what you currently have for a computer (All specs or computer model).

Fastest CPU that supports is a Pentium D 950 if updated to the 0312 BIOS. This would you a dual core CPU which would speed up your system a bit. But even this cpu is slower than a $60 Phenom II X2 550 or a Pentium G series from Intel. A Phenom II or Pentium G would require a new Motherboard, Memory, PSU, and Case.

But again this is all dependent on what you are willing to spend on an upgrade.

Each generation appears to be about 40% faster than the previous for the same clock speed based on what I've observed across the past few generations. Upgrading from a 3.2 GHz CPU means you'd need 2.3 GHz to get matching speed for a single generation forward, 1.6 GHz for 2 generations forward.

A Pentium 4 570J can be bought for very little and it sure is a big improvement over your current CPU. Note that you need a good fan to keep them cool.

When we first released the Intel® Core™ 2 Duo processors I bought a Intel Core 2 Duo E6400 at 2.13GHz and came here on Tom's to see how it was benchmarking agianst the Intel Pentium Extreme Edition 965 3.73GHz. Come to find out that the Intel Core 2 Duo E6400 processor would outperform the Intel Pentium Extreme Edition 965 in 16 of the 20 benchmarks that they ran at the time. So yes a lower rated processor can outpreform a faster rated one if the lower one has a better microarchitecture.

It depends on the micro architecture.

There was a time about 10 or so years ago when the AMD processors would outperform similar Intel processors when both were running at the same clock speed. AMD started naming their processors differently so consumers could compare them more favorably with Intel. Since that time Intel has improved considerably and has far surpassed AMD processors. I bought my first core2duo processor about 3 years ago. Since that time Intel has brought out 2 more generations of CPU's, each generation will run about 15% faster then the previous generation, if you set them at the same clock speed. But then the other big evolution is that each generation of new processor will run at a faster clock speed than the previous generation.

Depending on what you are doing, a processor with more cores can improve your performance too. Going from one core to 2 cores is a big improvement. For a power user going to 4 cores is another improvement, other people might not see as much improvement.

I have found a

get a c2d, it would be a lot faster than your current one

Intel Core 2 Duo. They are not compatible with your motherboard. I suggested a $20 upgrade (Pentium 4 3.8ghz 570J ), caqde wrote that the Pentium D 950 is the fastest supported CPU ($30-$40 on eBay). Better processors require a new motherboard and memory. What's your budget? That would help us make appropriate recommendations.

I guess I was wrong, the pentium D is the best you can use with that motherboard. you should be able to buy one for less than $50 online.

It won't kill it, but it won't work unless you buy a new motherboard. If you do, then you should consider a much better motherboard/CPU combination.

I replaced the factory processor with the one recommended, Pentium 4 3.8ghz 570J , and all that would happen is the fans came on.

It all comes down to performance per clock and almost all modern cpus are noticeably faster than any thing your board supports with very few exceptions.

I suggest you try to hunt down a cheap Pentium D 945 or at the very least a pentium d 820. They are both dual cores but i/o will take a performance hit but will still blow away what you have right now. A extreme edition Pentium D 840 has hyperthreading so it is quad threaded. Two cores but four total threads.

Don't bother with single core cpus unless that is all you can manage.
