Radeon R9 390 with 4GB of Memory Graphics Card Launched

Most recently, with the launch of NVIDIA GeForce GTX 960 displacement with 2GB video memory models with 4 GB, realizing that this is the absolute minimum for any modern video card. So did AMD, releasing Radeon R9 380 with 4 GB of memory on board. Now manufacturers of graphics cards introduced a new version of the Radeon R9 390. They kept the configuration "2560:160:64", but lost by exactly 4 GB of GDDR5.

It's quite interesting in its price range solution with good performance, based on the chip Grenada, the default was equipped with 8 GB of video memory with 512-bit bus access. But this volume is too big for even the Radeon R9 390X: tests showed Radeon R9 Fury X, even in 4K with proper compression techniques you can do to 4GB memory, Radeon R9 390 - clearly not the class map to use it in resolution 3840 x 2160. But the present cost of 8 GB of memory is effected and therefore, the price of the final product turns out less attractive.

Consequently, a return to 4GB - particularly so the size of video memory provided Radeon R9 290 and 290X - it is a very logical step. This step is accomplished by graphics cards manufacturers such as Sapphire, XFX and PowerColor. Perhaps for systems CrossFireX presence of 8 GB of memory, and plus - the performance of such a system is already sufficient for the games in 4K, but those who want to buy something more powerful than Radeon R9 380X, much more will be happy the price: if the official price of the ordinary Radeon R9 390 is $ 329. Due to the refusal to 8 GB of video memory AMD partners managed to reduce the cost of their decisions to $ 299 or even lower. GeForce GTX 970 NVIDIA, which is also equipped with 4 GB of video memory, there was a dangerous competitor.

But it should be remembered that the new driver AMD confirm a significant increase is not even on the latest architectures GCN: Grenada is a modified version of Hawaii, but the chip that was announced long before even the first generation of architecture Maxwell, in October 2013.

A number of new models Radeon R9 390 is already released, and, as shown by the first tests, new products are not inferior to Radeon R9 390X due to factory overclock and more aggressive profile of the frequency prescribed in the BIOS. At Sapphire Radeon R9 390 Dual-X OC, particularly will easy to switch the frequency of memory and memory bandwidth is increased from 320 to 384 GB/sec. While the other two solutions, PowerColor Radeon R9 390 4GB or XFX Radeon R9 390 Black Edition, have 6GHz. With regard to the comparison with the original Radeon R9 290, the data due to increased frequencies approach about 9-10%.
