Power Consumption, Temperatures, Noise and Overclocking

Although Gainward GTS250 2048MB uses the same PCB and components as Palit GeForce GTS 250 1GB, we measured its power consumption on our special testbed one more time. The testbed was configured as follows:

  • Intel Pentium 4 560 CPU (3.6GHz, LGA775)
  • DFI LANParty UT ICFX3200-T2R/G mainboard (ATI CrossFire Xpress 3200 chipset)
  • PC2-5300 SDRAM (2x512MB, 667MHz)
  • Western Digital Raptor WD360ADFD HDD (36GB)
  • Chieftec ATX-410-212 PSU (410W)
  • Microsoft Windows Vista Ultimate SP1 32-bit
  • Futuremark PCMark05 Build 1.2.0
  • Futuremark 3DMark06 Build 1.1.0

According to our standard methodology, the 3D load was created by means of the first SM3.0/HDR test from 3DMark06 running in a loop at 1600x1200 with forced 4x FSAA and 16x AF. The Peak 2D mode was emulated by means of the 2D Transparent Windows test from PCMark05. We got the following results:

Everything proved up to our expectations and we didn’t see any significant differences between the results obtained on Gainward GTS250 2048MB and Palit GeForce GTS 250 1GB: this GeForce GTS 250 model consumes a little over 80W in 3D mode, which is way below the readings taken off Radeon HD 4850. I would like to mention one more time that using two power connectors seems to be unjustifiably excessive for the current power consumption readings of G92b chip.

The thermal readings were also quite logical:

As you see, there is not that much difference from Palit GeForce GTS 250 1GB and the overall cooling efficiency is way higher than by the reference Nvidia cooling solution. Only the owners of small cases with poor ventilation should worry about possible overheating, because as we have already said before, Palit cooling solution doesn’t take hot air outside the system case.

The noise readings are also similar to what we took off Palit GeForce GTS 250 1GB and are overall pretty low. The cooler is almost noiseless even in an open testbed, and we couldn’t hear it all inside our system case equipped with a relatively noisy power supply unit. At least this is what you get once the operating system and drivers are loaded, because until then the fan rotates at maximum speed and generates quite a bit of noise.

Even an overclocking attempt undertaken for Gainward GTS250 2048MB bore almost the same results as we got during Palit GeForce GTS 250 1GB overclocking, at least during GPU overclocking part:

We managed to raise its frequencies to 800/1984 MHz without losing stability. The memory overclocked a little better and worked stably at its nominal frequency of 1200 (2400) MHz. We considered the obtained frequency gains to be significant enough to affect the performance in contemporary games that is why we decided to test Gainward GTS250 2048MB in overclocked mode as well.
