Kepler states that core-for-core, AMD’s Zen 5 core is more than 40% faster than Zen 4. He states that this performance is achieved in the SPEC benchmark but doesn’t explicitly state if the figures are based on integer or floating-point metrics. Considering that Integer-based performance helps more since more applications use it, it will be great for both single and multi-threaded workloads.
