Over the years, advanced manufacturing technology has been the killer of Intel, but now it is in awkward situation. The 10nm process has been delayed for three years, and it will continue to wait until the mass production in the second half of 2019.
In contrast, the opponents are leaping forward. Taiwan Semiconductor Manufacturing Co., Ltd. and Samsung Electronics Co., Ltd. are all investing in mass production in the 7nm process. AMD also used 12nm, which surpassed Intel for the first time.
Although the technologies of different homes are not directly comparable, Intel’s technology is indeed relatively advanced, but it is hard truth that it can be accepted by customers.
The 12nm used by AMD's Ruilong 2nd Generation is actually an optimized upgrade of GlobalFoundries 14nm, some similar to Intel's 14nm+, 14nm++.
AMD said 12nm greatly improved the transistor performance, the maximum operating frequency increased by 200MHz, while the full-core frequency is reduced by about 50mW, the same frequency power consumption decreased by 11%, the same power performance increased by 16%.
Seen from the product specifications, the second-generation Ruilong did achieve a significant increase in frequency while keeping power consumption constant or slightly increasing, and multi-core acceleration was also higher.
GamerNexus compared the frequency/voltage curves of the Ruilong 7 1700, Ruilong 7 2700X two generations of products, confirming that the 12nm effect is indeed quite obvious.
The minimum voltage of the 1700 at the full-core 3.5GHz frequency is 1.069V. At this time, the internal core temperature is 49°C, and the EPS12V circuit current is 7A, corresponding to a power consumption of 86W.
The 2700X requires only 0.906V, reducing it by as much as 15%. The temperature is only 39.8°C, the current is reduced to 5.6A, and the power consumption is about 69W, saving 20%.
As the frequency increases, The 2700X is always stable at lower voltages, 1.162V at 4GHz and 1.406V at 1700, still 15% worse.
Further up, 1700 with the original radiator can not run, The 2700X can continue to reach 4.1GHz with a corresponding voltage of 1.244V.
The next step is to replace the 2700X with a better Tt heatsink that can go all the way to 4.2GHz. At this point, the voltage is still only 1.381V, which is 2% lower than 4GHz 1700!
However, after the frequency exceeds 4.1 GHz, the 2700X performance is not very stable, and it occasionally crashes. It is unclear whether the overclocking limit has been reached or the physical condition of the test sample has been solved.
In any case, with the new process and optimized architecture, the second generation of Ruilong has lower operating voltage, corresponding lower power consumption and heat, and is also more advantageous for overclocking.
