WebJan 24, 2023 · From AMD's ISSCC presentation, Bulldozer's L1D switched to using 8T, 0.294 μm 2 bitcells, compared to the 6T ones used in 45 nm K10. 8T means that eight transistors are used to store every bit, reducing storage density. But AMD needed 8T bitcells to improve performance at lower voltages, increase clocks, and reduce power usage.

WebAMD tried to move from a wide, high-IPC, low-clock design to a narrow, low-IPC, high-clock design. To make that work, they had to achieve both high clocks and high core counts while retaining reasonable prices. The Bulldozer family fundamentally needed a 50% clock speed advantage to keep up with the same number of Phenom II cores.
