PENTIUM D question why isnt there hyperthreading

i recently bought a pentium D CPU 3.40GHz and it says 2 core 2 threads (according to cpuz) but task manager only shows 2 cores i was wondering if its supposed to be dual or a quad core like

More about pentium question isnt hyperthreading
  1. LoL one thread per core and modern Pentium D line has no hyperthreading.
  2. The "D" means dual.
  3. Hi :)

    The honest answer is..its too old....cpus have moved on fast in the last few years....

    All the best Brett :)
  4. When we released the Intel® Pentium® D processors it was throught that they wouldn't need hyper-threading because they would have a second core. Before long we would release the Intel Pentium Processor Extreme Edition 965 that would would have hyper-threading on both cores (this was the fastest of our Intel Pentium D processors at 3.73GHz). One of only three Intel Pentium D processors that would have hyper-threading. The other two are the Intel Pentium Processor Extreme Edition 955 and Intel Pentium Processor Extreme Edition 840 that both had hyper-threading.

  5. hyper threading would show as 2 cores 4 threads.

    Brett it was perfectly possible to get a P4 with hyperthreading.
  6. The Intel® Pentium® 4 3.06GHz 533 FSB was the first of the Intel Pentium 4's to have hyper-threading. Then most of the Intel Pentium 4 processors that had a 800MHz FSB would also have hyper-threading. Then the Intel Pentium Ds that I listed above. We would stop using hyper-threading during the Intel Core™ 2 Duo and Intel Core 2 Quad day but we would released it in the 1st generation Intel Core processors like the Intel Core i7-920.

  7. so why then would i need 2 threads, my last Pentium D said only one thread?

    also would any extreme edition processors work with my mobo i have the dell xps 400 Desktop W/ the 0YC523 model board
  8. don't know about that, but its telling you total threads and total cores, i.e. 2 cores giving you a total of 2 threads. might have been an update to cpu-z? or whatever you are using to see that?
  9. The Intel® Pentium® D was a dual core only processor. There were a couple Intel Pentium D that had hyper-threading (that I brought up above) and they would show a total of 4 threads. If a Intel Pentium D were showing only one core it would have to be due to a problem with the bios or OS not seeing the processor's core correctly.

  10. pentium Ds always had 2 or more threads. you either had the wrong cpu or read it wrong.
