Is the 4670-256 card reliable or should I run away?

Friends, I'm from Russia. Now I want to buy try imac (acquaintance with the system). You need to type text, watch web pages, watch movies. Home office 10-15 hours a day, work from home while the whole world is sick. They offer me a 2010 model (508) and they say that the 4670 card is very good. I read that 2011 is sick and the 6970 card is dying. Tell me, is the 4670 card also dying quickly? 3-5 years work every day. Thank you

Dedicated GPU MXM boards being discussed:

  • The 2010 iMacs either have an AMD Radeon HD 4670 or Radeon HD 5670
  • The 2011 iMacs have either an AMD Radeon HD 6750M or Radeon HD 6770M.

So what is the deal? There are lots of reports of the boards dyeing!

Lets look at this in a different way… back in 2009 & 2010 when these systems where being designed what where the types of applications being used? Mostly simpler text type of apps and in the gaming space graphics text blocks were still being used like the original DOOM game, over time better graphics were used with each generation of the game.

But! the amount of CPU & graphics processing was increasing! So older systems just couldn’t keep up with the added load. Just like pushing anything beyond what it was designed to support something has to give! Thats the core issue here as any iMac can be pushed too hard. History of DOOM (1993 - 2020) So clearly the iMac was not intended to be a serious gamer system. Maybe simple card games and watching video’s was its limit.

There is still another issue and that is lack of maintenance! You change your cars oil out and replace the air filters so your engine lasts. So do you dust out your system cleaning the fan blades and heatsink fins so the required cooling air is able to get through? After five or six years clean off the old thermal paste from the CPU and GPU chips refreshing it with the proper thermal paste and pads?

So between the age of the system and the lack of maintenance these old systems have their limits! So look asa getting your system serviced so its clean and the thermal paste has been refreshed so it is effectively able to cool. And clearly don’t play DOOM games or other heavy graphics stuff as you system is just not able to support them.

Last point, I strongly recommend you install a good thermal monitoring app like TG Pro to help in both monitoring your systems heat but when needed boost its cooling as well when needed!

So you need to think through how are you planing on using your system, and respects its limitations. And of course take care of it! cleaning it and monitoring its heat levels.

If I understand you correctly, the machine is a translation, then if I need to watch a 720p movie, type text, watch the Internet page and monitor the temperature, then the 4670 card will be alive for 3-4 years?. 2011 year 21.5 (map 6750) is also good if the service and temperature are cool? What should be a comfortable temperature for the cards 2010-2011

@Николай Н - Clean the dust out is #1 and then clean and replace the thermal past and pads on both the CPU and GPU heatsinks #2. For #3 install TG Pro to watch your temps it will tell you when it's getting to warm.

All four boards had there limits, the more powerful HD 6770M needs more more monitoring as the fan may not kick in soon enough. And HD 4670 & HD 5670 can overheat and break down sooner than the HD 6750M.

@danj In terms of the risk, I call FUD on that to a point. I run Affinity Photo and Designer on my 2014 15" Iris rMBP, and it's not dead (Iris+dGPU was a lot more back then, and still is). If this was a big issue, would my system not be at risk of a bad CPU connection or running slow since it pulls double duty? I never redid the thermal past either, but I got it from an ITAD.

However, I took the bottom off and blew some canned air through the heatsink and fans when I took posession. I also blow canned air though on occasion with the cover in place as well. Next time I open it, I will probably redo the thermal paste as it's now 7 years old.

@danj thank you, thank you. I'm thinking of buying 2011 21.5 (6750m)

@danj Will the 2012 gt 640 be much better and more reliable than the 2011?
