With NVIDIA’s upcoming Maxwell graphics cards AMD wants to make some noise and is working on two cards, the R9 280 and R7 265. Of course these cards are nothing really new, just rebrands of older cards.
The first card the R9 280 will be the 6th card in AMD’s R9 Series. It will be based on the 28nm “Tahiti” silicon, with a configuration identical to that of the Radeon HD 7950. So the card will feature 1792 stream processors, 112 TMUs, 32 ROPs, and a 384-bit wide memory interface that holds 3 GB of memory.
The card could have clocks of above 800 MHz for the core and 5.0 GHz (effective) for the memory. That will work out to 224 GB/s of bandwidth. Given that the MSRP of AMD’s R9 280X is $299 AMD could price this card at a sub-$300 price.
The R7 265 is going to be setup to compete with NVIDIA’s GTX 750. While you may think that this card would be based off the same “Bonaire” silicon that the R7 260X is based on, it is actually based on a cut down version of the “Curacao” silicon that is used on the R9 270 and R9 270X. This card will feature a configuration similar to the Radeon HD 7850 with 1024 stream processors, 64 TMUs, 32 ROPs, and a 256-bit wide memory interface.
The clock speed is expected to be 900 MHz and the memory at 4.8 GHz (effective), that works out to 153.6 GB/s of bandwidth. AMD will most likely target the $149 – $159 segment with the R7 265.
