Samsung Touts 4 GHz Memory for Graphics Cards
Getting more speed is always nice - and Samsung is about to break the speed barrier yet again, pushing GDDR4 chips to 4 GHz and beyond. At the International Solid-State Circuits Conference (ISSCC), Samsung presented its new GDDR4 memory chips that operate at about 40% higher speed than GDDR4 was initially estimated to, but use more power.
4 GHz GDDR4 memory chips are only "available" in 512 MB capacities and were manufactured using 80 nm process technology. They were designed for a power supply voltage of 1.4 V - 2.1 V, reports PC Watch web-site. The data rate of 4 Gb/s (4 gigabit per second, or 4 GHz) was achieved with devices operating at 2.0 V, which is higher than Samsung's current-generation GDDR4 chips that can function at up to 1.9 V officially.
GDDR4 memory at 4.0 GHz delivers bandwidth of 16 GB/s and if such chips were used in today's graphics cards that have 256-bit memory bus, this would result in peak data bandwidth of 128 GB/s, two times more than the ATI Radeon X1950 XTX (the only graphics card on the market that uses GDDR4) can offer. For tomorrow's graphics boards that will have 512-bit memory access Samsung's new chips would give peak memory bandwidth of 256 GB/s, which is nearly three times more than 86.4 GB/s that the currently highest-performance graphics card - NVIDIA GeForce 8800 GTX - has.
Are we beginning to enter the era when GPU memory will be clocked many times higher than our CPUs?

hehe jk
edit: oops I did'nt notice the double post. The difference is the rock-out headbanger icon shows that I am very excited about this indeed hehe.
