Since publishing our annual graphics card roundup we've received several reader inquiries regarding the performance difference between GPUs sporting 2GB and 4GB. Therefore we've put together a clock-for-clock comparison of the GeForce GTX 960 and Radeon R9 380 using 2GB and 4GB cards. Also along for the ride is the previous-gen Radeon R9 290 4GB and the rebadged R9 390 8GB. So here's debunking the myth of VRAM once again.
Although the Radeon R9 380X is based on the latest Graphics Core Next architecture, at its roots you will find a graphics card that is almost four years old now, the venerable Radeon HD 7970. Debuting back in 2012, the 7970 ran for a cool $550 and was at the time AMD's flagship part. The R9 380X starts at $230, but does it deliver?
Based on the fully fledged Fiji XT, the Radeon R9 Nano gets the same 4096 stream processors as the Fury X, just in a much more compact package. The Nano measures only 6" (152mm) long, which is made possible by the Fiji GPU's modest power consumption and HBM technology. AMD hopes to enable 4K gaming in tiny Mini-ITX systems with the Nano.
