Video Card: 1GB/DDR5 or 2GB/DDR3

Fri Jul 05, 2013 8:05 am

I am looking for HD7750 and wondering if I should get one with 1GB/DDR5 or 2GB/DDR3. Any advice is appreciated.

Definitely 1GB DDR5 for any card that will never be playing games above 1080p resolution.

What are you using this card for? Is the lack of PCIe power connector, lower power consuption, and/or card size important?

This 7790 is the same price ($100) as the 7750's you've linked and will be more than twice as fast. I don't have any direct comparisons, but the 7770 is ~18% faster than a 7750 and the 7790 is ~85% faster than a 7770. (those are rough numbers since the game settings and games tested aren't the same for the 7750 and 7790) Irregardless, the 7790 is obviously better performance for the same price as a 7750. The 7790 only uses about 30W more under load than the 7750 as well.

Summary: 7790 offers ~2x performance of a 7750 with only ~25% higher power consumption.

It appears that one with 1GB/DDR5 is better choice.

Softwares I will be using is Photoshop/Illustrater CS6 and 3DXMax 2012. I also do video capturing and editing using Roxio and ArckSoft. I never play game. I thought HD7750 would be adequate for the above. The PSU is Corsair CX430M so that HD7790 can be used but do I really see difference using HD7790 with 30W more power consuption?

I can't comment on how much quantitative difference you'll see between a 7750 and 7790 in the programs you're using, it may not be a ton. I do know that hardware acceleration (OpenCL/OpenGL) is being used more and more in such programs. System power consumption with a 7790 uses 50W idle and 115W load and the 7790 Bonaire GPU has finer grained power management so it will theoretically be more power efficient through the entire range of usage (comparatively speaking). At idle the difference would be minimal, so unless the GPU is constantly being pegged in a 24/7 usage, you probably won't notice much difference on your power bill (just turn off a single light bulb somewhere and you'll save more energy). Again....for the same price :-?

If the 7750 is preferable for the lower power usage and you've got decent airflow through your case, this passively cooled 7750 would give the added benefit of silence.
