ARM is irrelevant, that's just the instruction set.
#GEEKBENCH 4 REVIEW FOR MAC OS X X86 (64 BIT) FULL#
Also it'd vastly depend how fast the CPU can switch to full turbo mode (for servers that doesn't matter at all) If both fits the CPU caches - the results are supreme, if not - horrible compared to the former. They compress just 450KB of text as a benchmark - even the dict size is greater then the input. The workload uses the LZMA SDK for the implementation of the core LZMA algorithm. LZMA features a high compression ratio (higher than bzip2).The LZMA workload compresses and decompresses a 450KB HTML ebook using the LZMA compression algorithm. The algorithm uses a dictionary compression scheme (the dictionary size is variable and can be as large as 4GB). Integer WorkloadsLZMA CompressionLZMA (Lempel-Ziv-Markov chain algorithm) is a lossless compression algorithm. The tests are very short, no power or thermally limited. Geekbench is a horrid benchmark.The amount of info on how they run the tests is extremely limited (mostly what lib they opted to use). It will be interesting to see how much performance they can get when they are on a level playing field when it comes to power and cooling constraints. >In the face-off against a Cortex-A55 implementation such as on the Snapdragon 855, the new Thunder cores represent a 2.5-3x performance lead while at the same time using less than half the energy. Apple's "little" cores were a new design in the A13, and compare very well against stock ARM cores on a performance per watt basis.
I think performance per watt is going to be just as important as overall performance. In SPECfp2006 the A13 is still roughly 15% behind. This year, the A13 has essentially matched best that AMD and Intel have to offer – in SPECint2006 at least. Last year I’ve noted that the A12 was margins off the best desktop CPU cores. The difference is a little bit less in the floating-point suite, but again we’re not expecting any proper competition for at least another 2-3 years, and Apple isn’t standing still either.
In the mobile space, there’s really no competition as the A13 posts almost double the performance of the next best non-Apple SoC. >Overall, in terms of performance, the A13 and the Lightning cores are extremely fast. SPEC is a better cross platform benchmark, since it's an industry standard and was designed just for cross platform testing.
