As reported, Advanced Micro Devices plans to introduce its new Radeon R9 and Radeon R7 300-series products in the second quarter of the year. While the new product line will carry new model numbers, it will include graphics processing units that will not be exactly new.
The Radeon R9 300-series lineup will consist of seven graphics adapters: Radeon R9 370/370X, Radeon R9 380/380X, Radeon R9 390/390X as well as dual-chip Radeon R9 395X2, reports 3DCenter. In addition, AMD intends to introduce Radeon R7 360/360X graphics boards for entry-level market segment.
The top-of-the-range Radeon R9 390/390X as well as the R9 395X2 graphics adapters will be based on the code-named “Fiji” graphics processing units. The new GPUs feature GCN 1.3 architecture, up to 4096 stream processors and will rely on high-bandwidth memory from SK Hynix.
The high-performance Radeon R9 380/380X will be powered by the code-named “Grenada” graphics chip that will be a revamped version of the “Hawaii” GPU. The novelty will sport 2816 stream processors, 512-bit GDDR5 memory bus and will offer performance comparable to that of the Radeon R9 290/290X. It is unclear whether the chip will feature any architectural improvements over existing GPUs.
The Radeon R9 370/370X will rely on the code-named “Tonga” graphics processing unit with up to 2048 stream processors and 256-bit memory bus.
The Radeon R7 360/360X will use code-named “Trinidad” graphics chip with unknown specifications and GCN architecture.
All-in-all, only AMD Radeon R9 390/390X graphics card will feature an all-new graphics processor with improved architecture and considerably higher performance compared to chips that are available today. All other graphics boards in the lineup will be powered by GPUs that are similar to those, which are already on the market.
