The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this. These results are taken with the system built inside the Bitfenix Colossus .
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test.
The reference cooler on the GTS450 is actually the best performer on test today with temperatures never exceeding 60c when gaming. The Powercolor HD5750 Low Profile card delivers a good result with temperatures in the mid 60s when playing Crysis. The single slot XFX cooler maintains a higher ambient temperature but under load manages to keep the card running at the same temperatures as the lower clocked Powercolor solution.
Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.
We can see that a single slot cooler isn't without limitations as the XFX card takes 7 seconds longer than the Powercolor solution to return temperatures to the idle state. The eVGA solution is the quickest, scoring around 9 seconds under our stressed conditions.
It is really good to see lower end cards reviewed here, the high end boards are great, but I doubt many people can afford them.
That XFX board is great. looks like a bargain to me.
This market is really so friggin sweet right now. anyone with a semi decent sized monitor, this is all they need. im not a gaming fanatic so maybe people wouldnt agree.
Nah its a good point Tom. if someone has a 1920×1200 screen, a 460GTX is all they need, unless they want crazy performance. 1080p, or 1680 then the cards on test today are great. the low end is so strong right now, it has to be killing high end cards sales.
I actually might pick one of these up for my kid brother for christmas. we are all putting a system together for him. cant believe how good the performance is for the price.
XFX and Sapphire, only cards to buy IMO
450GTS is good but I dont think its a dominating product like the 460 was. its killed 5830, and even hurt 5850’s. The 450 is a good board but the overclocked ATI cards are really going punch for punch.
I like that single slot design. the powercolor card is different but the shape looks weird.
Fantastic review, loads of detail and useful info.
wonder how long it will be for other sites to copy the return to idle concept 😉
GTS450 is a good card but I agree, it isnt dominating like the 460 is. the price is good and I like evga, this would be my choice out of the three, mainly cause I dont like catalyst.
@ Tri Color – Catalyst is great now, not a problem, I wouldnt let the drivers put you off the hardware.
@ Stefan – nah, they still suck. my buddy has a 5850 and the cat alyst 10.8 broke his HDMI scaling and every time he boots up he has to fix it. same with Cat 10.9. they are still a poor driver compared to nvidia forceware.
