Geekbench investigates up to 30% jump with Intel's iBOT — performance gain attributed to newly-vectorized instructions

Geekbench investigated a potential 30% performance boost with Intel's iBOT, attributing the increase to newly-vectorized instructions. Testing on an Intel Core Ultra 9 386H showed a 5.5% improvement in both single and multithreaded performance. While some subtests saw no benefit, others like object removal and HDR processing showed significant performance gains. iBOT reduced scalar instructions by 62% while increasing vector instructions by 1,366%, leading to improved performance through SIMD. Despite some downsides like a startup delay, this investigation sheds light on the potential of vectorized instructions for enhancing CPU performance.
