TechPowerUp writes AMD is also developing the Radeon R9 280, another card based on the 28nm Tahiti GPU. The R9 280 reportedly features an identical core configuration to that of the Radeon HD 7950, with 1792 stream processors, 112 TMUs, 32 ROPs, a 384-bit memory bus and 3GB GDDR5 memory. Pricing is expected to be under $300.
The Radeon R9 280 could be clocked above 800 MHz on the core, and 5.00 GHz (GDDR5-effective) on the memory, which works out to 224 GB/s of memory bandwidth. Given that the R9 280X is still on paper a $299 SKU, AMD may intend the R9 280 to be priced within the sub-$300 segment.
The actual retail price may be higher though depending on demand from cryptocurrency miners.
