Evidently the x86 tax is more noticeable on small phone-like cores but the tax doesn't magically vanish for big cores (only reduces the amount by a factor of about 2x or 3x). This is the reason why a 90W ARM SoC is able to offer 80--90% of the performance of a Haswell 140W Xeon. It is not because those companies have alien engineers working in the microarchitecture. It is not because they rely on an advanced SOI foundry process beyond Intel bulk strengths. It is the ISA advantage.

Intel didn't kill the old RISC guys because the "ISA doesn't matter". Intel killed them by a mere question of volume and basic market dynamics. Intel attacked all them with cheaper high-volume products and people started to buy the chip that provided a 80% of the performance at 50% cost. The small volume guys found they couldn't sustain RD costs at same rate than Intel could and were finally killed. More about this below.

You don't have to look at how poor the baseline is, but at the evolution rate and the time that takes to caught. There was an excellent paper presented at SC13 that studied such matters, it won a best paper award (SC13, November 17 - 21 2013, Denver, CO, USA. ACM 978-1-4503-2378-9/13/11)

The first figure in the papers plots the evolution of performance of the first vector computers against old RISC guys (MIPS, alpha, HP, SPARC,...) and against x86 (AMD/Intel). The Figure 2a compares vector vs commodity and 2b compares commodity vs ARM. The new processors always start from what you call a "crap baseline", but evolve a much faster rate (2--4x faster) and in few years caught the old processors in performance and replace them.

Given the trend discussed above, it is reasonable to consider whether the same market forces that replaced vectors with RISC microprocessors, and RISC processors with x86 processors, will replace x86 processors with mobile phone processors. That makes it relevant to study the implications of this trend before it actually happens.

We are not arguing about the superior energy efficiency of mobile processors, or about fundamental energy efficiency advantages of RISC vs CISC instruction sets. We agree that energy efficiency and performance are two axes in a design space, and that currently HPC and mobile processors have different targets, but this is subject to change at any time.

We do argue that the higher volume of the mobile market makes it easier for its vendors to amortize the costs of a new design, enables multiple vendors to survive and compete, and leads to faster product evolution, lower prices, more features, and higher performance.


In fact, AMD also knows that ARM will win over x86 and this is why it is now an ARM license.

ARM is a winner because has (i) ISA advantage (efficiency), (ii) volume/cost advantage (commodity hardware), and (iii) ecosystem advantage (no monopoly, customization, and so).

Apple has shown how a dual-core 1.3GHz phone-rated TDP processor is able to compete against quad-core ~1.5GHz tablet-rated TDP processors from AMD and Intel in raw performance. And "no", the reviews were not centered around Geekbench.
