Processor tops charts with 5.6CoreMark/MHz per CPU
Imagination Technologies has announced that its MIPS P5600 has entered the CoreMark chart straight at the top with a record-breaking score of 5.6CoreMark/MHz per CPU, beating the previous top score held by ImgTec's own MIPS proAptiv processor. The result has been certified by EEMBC, the long-standing embedded processor benchmarking consortium that designs and maintains CoreMark.
To put this result into perspective, a MIPS P5600 CPU delivers 20% more performance than its direct competitor while being significantly smaller in area, even scoring higher than Intel’s desktop line of CPUs. For example, an Intel Core i7-2640M processor achieves 14513.79CoreMark at 2.8GHz, or 5.18CoreMark/MHz - 7.5% lower than the latest result for MIPS P5600.
MIPS P5600 features a series of improvements over previous generation proAptiv CPUs, including enhanced fetch efficiency, reduced L2 cache latency and pre-fetching; additionally, improvements in cache replay and memory disambiguation contribute to gains in performance for a wide variety of real world-applications (e.g. memcopy performance).
This level of performance efficiency will offer a welcome boost to MIPS-based embedded processors used for power-sensitive applications such as mobile, home entertainment, networking, automotive and many others.
Importantly, these outstanding results have been achieved using the latest off-the-shelf GCC compiler. Customers can access this high-performance toolchain either as source from partners or packaged in SDKs from Imagination.
This approach is in contrast with some of ImgTec's competitors, who achieve their best benchmark scores with expensive, closed-source toolchains. Instead, Imagination Technologies is focused on building an open ecosystem that delivers performance quickly and painlessly, an important consideration for reducing time-to-market in mobile and embedded applications.
