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.
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. All fan settings were left on automatic.
The AMD HD7750 reference board manages to maintain a 76c limit when loaded with Furmark, the synthetic stress test. This drops to 68c when gaming. The XFX HD7750 Black Edition has the most capable cooler in that specific range, dropping temperatures to 52c when gaming – a commendable result.
The tiny fan on the Sapphire HD7750 low profile card doesn't spin that quickly although the modest clock speeds and low voltage keep temperatures down to 61c when gaming.
The surprise result of the test was the HIS HD7770 GHZ Ed IceQ X, which peaked at 79c when gaming. This is higher than we would like, but we would assume that HIS have upped the voltage a little to maintain stability at the greatly enhanced clock speeds.
Wow, that Sapphire card is really good. I had imagined I would get a prodigy case later this year and get a small video card for it ,just for video acceleration and image quality.
This looks the card to get.
I admit, you got me there.
i was expecting the HIS or XFX to win this, but you focused on EXACTLY the right points. power consumption, noise, size, lack of power connector etc.
Great job from sapphire, exactly what i need for my system, im using onboard and it sucks so badly for HD video. people dont understand the IQ differences between Intel on a CPU and a dedicated AMD card like this. its night and day. especially for colours and noise reduction options in the panel.
A HD7770 or GTX460 is more than enough, even today, for 1080p gaming. people get a false idea that a 7970 or 690 is ‘needed’. those are three screen solutions now. save the money, pick up one of these cards, classic little cost effective beasts.
Not sure im a big fan of these cards, but the sapphire model makes sense. im still wanting the 660, just trying to make sure I dont cripple myself for next month as I need to eat too.
Some good overclocks, but I agree, why did they reduce the shaders from 800? typical fing stupid AMD at times. they could be doing so much better if they had people making decisions who understood the gamers.
I like the HIS card best im afraid, if they hit £99.99 count me in for my second system.
These aren’t good enough for 1080p gaming, I want 60 fps, sorry. but good pricing now for people without the cash for a £200 card,. thats the sweet spot.
Am I missing something?
They are releasing ‘new’ 7750’s at 900mhz+? havent they been out for months already? you guys reviewed many.
bonkers AMD move. just drop the price, dont re-release them with bios updates. seems XFX were left out of the loop. Nice black reference edition :p
I bought a Sapphire flex 6770 flex from the last generation and its still good. I dont use AA and I have my system into a 37 inch tv. runs well.
Dont get sucked into the hype of needing 120fps for gaming, its bollocks.
