Cache of this SoC works at 2 GHz frequency, there are 16 KB L1i, 16 KB L1d, 512 KB L2 per core, and shared 4 MB L3 cache. L3 cache has 4 segments (1 segment per block of 4 CPU cores), each of 1 MB with 32-way associative. Cache uses directory-based cache coherency protocol. FT-1500 also has: [11]

All eight cores share 4 MB L3 cache, and the total transistor count is approximately 855 million. [9] The design was the first Sun/Oracle SPARC processor with out-of-order execution [ 10 ] and was the first processor in the SPARC T-Series family to include the ability to issue more than one instruction per cycle to a core's execution units.

The read bandwidth when a single Lion Cove core accesses the L3 cache has regressed from 16 bytes per cycle with Redwood Cove to 10 bytes per cycle for Lion Cove. Despite this lower bandwidth in reading and writing data, the latency of Lion Cove accessing L3 data has been reduced from 75-cycles to 51-cycles in Lunar Lake. [ 8 ]

The L3 Infinity Cache has been lowered in capacity from 128 MB to 96 MB and latency has increased as it is physically present on the MCDs rather than being closer to the WGPs within the GCD. [20] The Infinity Cache capacity was decreased due to RDNA 3 having wider a memory interface up to 384-bit whereas RDNA 2 used memory interfaces up to 256-bit.
