Context: CREATE TABLE table_269920_17 (l3_cache__mb_ INTEGER, model VARCHAR, qpi_speed__gt_s_ VARCHAR, speed__ghz_ VARCHAR)
Question: What is the maximum L3 cache of the processor whose speed is 2.00 GHZ, has a QPI speed of 4.8 gt/s, and is model e5504?
Answer: SELECT MAX(l3_cache__mb_) FROM table_269920_17 WHERE qpi_speed__gt_s_ = "4.8" AND speed__ghz_ = "2.00" AND model = "E5504"
