AMD® FX™-770K

The AMD FX-770K is a desktop processor with 4 cores and 4 threads. It launched in Dec 2014. Clocks run from 3.5 GHz base to 3.9 GHz boost. It uses the FM2+ socket. Rated TDP is 65 W.

The AMD FX-770K scores 1,478 in single-core performance and 3,225 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,183 for overall performance, 4,165 for productivity performance, 4,434 for creator performance, 3,104 for engineering performance and 5,240 for gaming performance. Its multi-core throughput works out to 806 per core, 806 per thread and 50 per watt. Its computed efficiency index is 271. Its performance index is 27, so its overall performance is 73% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the AMD FX-770K scores 18,437 in integer math, 5,312 in floating-point math, 54,466 in compression, 922 in cryptography, 219 in physics simulation, 2,014 in vector SIMD, 12 in the prime sieve and 5,949 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 69% below in integer math, 88% below in floating-point math, 76% below in compression, 92% below in cryptography, 80% below in physics simulation, 87% below in vector SIMD, 82% below in the prime sieve and 74% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The AMD FX-770K has 4 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 3.50 GHz and boosts up to 3.90 GHz.

The AMD FX-770K is a desktop processor and belongs to the AMD FX family. It launched in Dec 2014.

The AMD FX-770K has 448 KB of L1 cache and 8 MB of L2 cache. That adds up to about 8.4 MB of cache, or 2.11 MB per core.

The AMD FX-770K has a 2-level cache hierarchy: L1 at 448 KB and L2 at 8 MB. L2 is the largest level and makes up about 95% of the cache listed here.

The AMD FX-770K uses the FM2+ socket.

The AMD FX-770K has a rated TDP of 65 W.
