Pentium 4 HT vs Sempron 3400+

Which CPU is faster the Pentium 4 540J 3.2GHz with HT (socket LGA775, Prescott core) or the Sempron 3400+ 1.8GHz (socket AM2, Manila core)? Couldn't find any good reviews comparing the two. FYI both are 90nm CPUs.

  1. I'm sure the P4 cause it's almost 2x the clock speed.
  2. That was in the time when Hypertreading was as useful as wet toiletpaper on those chips.

    Like above said comparing those all chips is all about the clock speed as that was in the days when it was still GHZ wars not core wars like we get today. So who ever got the higher clock on his cpu would have the advantage
  3. well the sempron is a K8 (athlon 64 architecture) which is better then the pentium 4s so they don't have the same clock for clock performance.

    Not necessarily true. The Clock for Clock speeds on the AMD chip were much better than what intel offered at the time. And Athlon XP's and 64's walked all over pentium 4's for years.

    That was back when a 2.0Ghz Athlon 64 out performed a 3.0Ghz Pentium 4. AMD stopped the GHZ war and improved IPC while Intel just kept throwing more clock speed at the P4. :lol:

    Oh really?

    Intel Pentium 4 540 / 540J 3dmark 03 score 799
    AMD K8 Sempron 3400+ (rev. F2, 59W, CW) ->741
    AMD K8 Sempron 3400+ (rev. E6, socket 754) -> 645
  7. Please don't use 3dmark as a benchmark lol, completely Intel biased and remember it's the socket AM2 sempron I'm comparing.
  8. But... It's still a Sempron. If this was a Celeron vs Sempron it would be fairly clear the winner would be AMD. However, the Sempron is a discount-class processor while the P4 was their mainstream workhorse. I'm not a CPU wiz by any means, but based on that logic alone the P4 should outperform the AMD.

    Using the link that gnomio provided you can select other benchmarks, and going off of the SiSoft Sandra floating point test, the Intel WHOOPS THE CRAP out of the Sempron. I have a feeling this has to do with the instruction sets, and doesn't the Sempron lack a math co-processor like the Celeron's did?
  9. Hey don't beat on the Sempron 64 remember it's just a smaller cache version of the Athlon 64.
  10. In this case the P4 is probably faster. Remember that measuring with todays programs both are slower then slow. If this was an Athlon 3400 or 3500, I'd bet the AMD chip would be faster. If your into OCing then use the Sempron. It should OC a good deal better.
  11. Sempron was also lower clocked. The Athlon 3400+ was at 2.4Ghz (or 2.2) and the 3200+ was at 2.0Ghz or 2.2 depending on the socket and that would have been the competitor to the 540j
  12. I'd go with the Sempron since it uses less heat and if you want to use a 64-bit OS you have to use it. The Pentium 4 540J runs hotter and lacks 64-bit instructions.
  13. Best answer
    Both chips are terribly old and you probably won't notice much of a day-to-day improvement of one versus the other. Intel, back during that time frame, had a slight edge in media encoding while AMD pretty much was better in everything else.

    That being said, the Pentium 4 was a "mainstream" CPU of the era and the Sempron a budget chip. AMD had an advantage back then, but the Sempron's clock speed is simply so low that it won't really beat the Pentium 4. It would eat a Celeron of the time for breakfast, though.

    The Sempron will be a lot cooler running, but the P4 will generally give better performance. If you were comparing an Athlon 64 to the P4, though, the Athlon would walk all over it.

  15. P4 it is, I have a better mobo for it any ways lol.
