AMD to Launch New Single-GPU Card This Summer, to Take on GTX 780 Ti
AMD is reportedly working on a new single-GPU graphics card SKU to compete with the likes of GeForce GTX 780 Ti, and perhaps even take a swing at the GTX TITAN Black, since it's not too far ahead of the GTX 780 Ti at single-display gaming. The new SKU will be more than just a clock-speed bump, it will leverage HBM (high-bandwidth memory), a cutting-edge new technology that relies on stacking multiple DRAM dies with dedicated memory paths into a single package, cutting down on power-draw, thermals, and PCB real-estate.
The first kind of HBMs to hit the market are 8 Gbit 4Hi, which will interface with the GPU over a 128-bit wide path, which means there will be just four memory packages on the card (since the "Hawaii" silicon features a 512-bit wide memory bus), with improvements in the area of power-draw and heat output. The memory could be clocked higher, too. Sadly, memory bandwidth is not the prime-mover in VGA performance, and AMD will have to offer higher GPU clocks for the card to stand a chance against NVIDIA's high-end single-GPU offerings. As for the name this card would bear, we get a sense of deja vu about how NVIDIA launched the single-GPU GeForce 7950 GTX alongside the dual-GPU 7950 GX2, replacing the 7900 GTX. And so, it wouldn't surprise us if AMD named it Radeon R9 295X.
