Just so you know, I have an Intel Core i7-3770K 4.2 GHz! Which CPU is overall better? I only care about performance (power consumption and temperatures are not important what so ever)!

The pentium 4, it has a higher clock (on the same architecture) + hyperthreading.

While there are a couple different models of the Intel® Pentium® 4 2.8GHz (which socket is it? what is the cache?) that can give a little performance boost in the end the Intel Pentium 4 would be better than the Intel Celeron® because of the larger cache size.

Both answers are wrong. The Celeron 420 will easily beat out an ancient pentium 4 ht at 2.8ghz. Its not even that close. Also the pentium 4 takes like 3-4x more electricity then the celeron. celeron scores 456 vs 336 of p4 at 2.8ghz.

To put it into perspective an i7 3770k at 4.2ghz takes similar electricity under 100% cpu load to a pentium 4 2.8ghz ht and your 3770k is about 20x faster.

Heck 1.6ghz pentium m's released when p4s were around destroyed p4's at 1/4 of the power consumption.


Oops! Sorry I didn't realize that the celeron 420 was Conroe. Seeing as he didn't care about power consumption or temperatures, but there still is hyperthreading in play here giving you two threads, but the clock rate is irrelevant I would say that this could be a wash.. I don't know that it's worth the switch. If you want to upgrade get something that is still Conroe/Wolfsdale based.

I remember using a 1.3ghz pentium m system and 1.5ghz pentium m system and a 1.6ghz p4 and 2.66ghz p4 and the pentium m destroyed it and you could not hear it on and had 10 hour battery life in a laptop and played games better even the desktop with 1.6ghz p4 had a lot faster graphics card games like need for speed underground the 1.3ghz pentium m was 2x better then a 1.6ghz p4 and the 1.3ghz pentium m at similar time in 2003-2004 took 1/5th of the electricity. Not only that flash games like teagames ran so much better on a 1.3ghz pentium m then a 2.66ghz p4 and 1.6ghz p4, about 3x faster and was in fluid motion and p4 systems struggled watching videos on pentium m breezed past it.

Now considering intel had technically a 5x better performance per watt cpu's when pentium 4's were released nowadays we are looking at close to over 50x better performance per watt then pentium 4's.

I currently have an i5 3317u in my laptop and it is about 6x faster gflops wise then a 3.8ghz p4 ht and takes 1/8th the electricity to run so close so around 48x better performance per watt then an intel p4 at 3.8ghz. Quite impressive though.

Yes, a 1.6 GHz Intel Centrino (Pentium M) eats 3.2 GHz Pentium 4s for breakfast! I have already visited cpubenchmark.net to make a comparison, but I also know that some CPUs aren't ranked correctly. For example: Intel Core i7-3940XM = 9,820 points / Intel Core i7-3770K = 9,630 points (this is not correct, because those CPUs are exactly the same, the only difference is that the Intel Core i7-3940XM is for laptops and the Intel Core i7-3770K - for desktop systems, everything else is the same)! Another example: Intel Core i7-995X = 10,374 points (Gulftown, 32 nm, 6 cores, 3.6 GHz ~ 3.86 GHz) / Intel Core i7-990X = 9,364 points (Gulftown, 32 nm, 6 cores, 3.46 GHz ~ 3.73 GHz) - a 1010 point difference only for 0.13 GHz higher clock speeds! If you are wondering why I want to know which CPU is better, the Celeron 420 or the Pentium 4 HT 2.8 GHz, here's what happened. My Intel Pentium 4 HT 2.8 GHz broke because of an electric shock which destroyed the motherboard and PSU as well (it was caused by an overclocking failure). I had to buy a new motherboard (with the same socket as the previous one - 775; it was also second hand), 1 GB DDR2 (the previous RAM worked but was DDR1, incompatible with the motherboard), a new PSU and a new CPU (the guy from the shop only had a 1.6 GHz Intel Celeron 420 CPU from the 775 LGA processors). He only told me that it was a 1.6 GHz Celeron and at first this shocked me, but when I found out at home that it was an Intel Celeron 420, I redeemed faith in it. All I want to know is if the new Celeron 420 has higher overall performance compared to my dead Pentium 4 HT 2.8 GHz.

notebookcheck is good benchmark test. Old processor can be seen ticking off archived cpu's. Also tick the cpus you want to compare and click on restrict near the top. Also click on the benchmarks you want.

This thread shows various systems gflops:

This is cinebench pure cpu benchmark:

The celeron 420 is a lot faster then a pentium 4 2.8ghz ht. Don't worry about that at all. Not only that the heat given out will be very cool vs a pentium 4 that will be like summer in an air conditioned room. A pentium 4 is like an i7 3770k running at 5ghz heat output wise vs a celeron 420 is like a low clocked core i3 desktop heat output wise.

Thanks! I am very happy that I got myself a better processor! It was very hard to tell if the Celeron 420 had higher performance or not, because both it and the Pentium 4 HT 2.8 GHz failed to play HD videos above 720p properly with my GeForce 6200 TurboCache 256 MB which survived the electric shock!

I have just overclocked my Intel Celeron 420 to 3.0 GHz! It beats the Intel Pentium 4 HT 2.8 GHz for sure now! I can even watch videos in 1080p Full HD without any problems what so ever!
