Intel Pentium 4 HyperThreading-Spezial: Benchmarks in multitasking scenarios

Multitasking With Flask

I bought a new film in the store, which was immediately saved in the archive on the home hard drive t must be included in the appropriate conversion to MPEG4 format? We have already been able to show that converting to the required format with FlaskMPEG with Hyper-Threading is much faster, but converting a complete film still takes time. But playing or working while Flask is running in the background has been a game of patience or not possible at all. Can Hyper-Threading Technology help here?

and Quake 3

Flask and Quake 3 Arena
  • Normal:
    • Without load
      353,6
    • P4 3.06 HT an
      213,9
    • P4 3.06 HT off
      204,3
  • Max:
    • Without load
      301.6
    • P4 3.06 HT an
      204,8
    • P4 3.06 HT from
      179.7

In Quake3 Arena and Flask running at the same time, the Pentium4 can increase its performance in 'normal settings' by almost 5 percent through Hyper-Threading. Under 'Max Settings' it is even enough for an increase in performance of almost 14 percent. But of course the additional load does not remain without effect on the performance. However, this would also be presumptuous.

and 3DMark2001

Flask and 3DMark2001 SE
    • Without load
      13,099
    • P4 3.06 HT an
      8.434
    • P4 3.06 HT from
      6.883

In 3DMark2001 SE, the Pentium4 can increase its performance by 22.5 percent through Hyper-Threading and thus achieves 122.5 percent of a similarly clocked Pentium4 without Hyper-Threading. Nevertheless, the result is more than 35 percent behind the 3DMark2001 SE performance achieved without additional load.

and UT2003

Flask and UT2003
  • Flyby:
    • Without load
      162,3
    • P4 3.06 HT an
      80,3
    • P4 3.06 HT from
      54 , 9
  • Botmatch:
    • Without load
      75,9
    • P4 3.06 HT an
      32.7
    • P4 3.06 HT from
      28.2

Certainly the offered performance drops quite sharply when Flask and UT2003 are running at the same time, but with Hyper-Threading you can get almost 36 frames per second more here in the flyby, which is a performance increase of 46 percent compared to one 3.06GHz Pentium 4 without Hyper-Threading. In the botmatch, in which the processor has to do a much more important and complex job, the performance with Hyper-Threading still increases by almost 16 percent.

and Comanche4

Flask and Comanche 4
    • Without load
      62,2
    • P4 3.06 HT an
      31,4
    • P4 3.06 HT off
      30,4

Comanche 4 must be included additional load will lose almost 50 percent of its performance and even Hyper-Threading can only help to a noticeable increase in performance to a limited extent. The performance of Comanche 4 increases by a little more than three percent when Hyper-Threading is activated.
