Radeon R9 390 is a High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.
It equips a GPU Codenamed Grenada PRO which has 60 Compute Units activated and thus offers 2560 Shader Processing Units, 160 TMUs and 64 ROPs. The Central Unit is clocked at 1000MHz.
The GPU accesses a 8GB frame buffer of fast GDDR5, through a 512-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1500MHz.
With a rated board TDP of 275W, it requires at least a 750W PSU with one available 6-pin and one available 8-pin connectors.
Radeon R9 390 8GB competes with GeForce GTX 970 and is essentially a Higher Clocked Radeon R9 290 with the addition of twice as much video memory (8GB against 4GB).
It proves to be slower than GeForce GTX 970 at resolutions up to 1920x1080 but takes the lead beyond that.
However, the lack of DirectX 12.1 Support paired with the enormous Power Consumption (almost twice as much as GeForce GTX 970) and the Gimmicked 8GB Frame Buffer, makes it an extremely uncompetitive product.
Radeon R9 390 is best suited for resolutions up to and including 2560x1440. We recommend a Very Strong Processor and 8GB of RAM for Optimal Performance.
can i buy this without any problems ?
also would this be enough to run any new game out there ? i know silly question, but i need to be sure.
Can i use this GPU with 500 watts PSU?
Can I Buy it with no issues ?
can i upgrade my current gpu to this without bottleneck
im looking for a new gpu and i could use some help, the once im potentaily thinking about buying would be the 7990, the gtx 970 or r9 390, all of them i could get for around 300 to 350 buckoronies, ty for reading :)
I got this card and performance wise is awesome. I got a question; what is the temperature limit for this card? I was just wondering this so I can keep eye on.
Thinking about getting the r9 390, anyone know if it´s a soldid upgrade? Cheers!
will this be able to run on my corsair cx 750?
Hi, I am thinking up upgrading with this card as well as getting 8 more gigs of ram. Will my cpu be bottlenecked with this addition?
