Table schema:
CREATE TABLE table_name_71 (gpu_frequency VARCHAR, frequency VARCHAR, sspec_number VARCHAR)

Question: What is GPU Frequency, when Frequency is 1.67 GHz, and when sSpec Number is SLBX9(A0)?
SQL: SELECT gpu_frequency FROM table_name_71 WHERE frequency = "1.67 ghz" AND sspec_number = "slbx9(a0)"
