But, the tipster also pointed out that the clock speed will be dependent on the manufacturing yield of the SF2P process from Samsung Foundry. As per the leak, Samsung needs to have manufacturing yields higher than 65 to 70 percent to attain the targeted performance. But since there has been no official announcement about the specifications, the info can be considered a rumour.Leak points to higher performance targetThis recent one is in stark contrast to the previous benchmark table of Exynos 2700, which leaked from Geekbench.The new chipset, which has the part number S5E9975, was released with a 10-core CPU design. Based on the listing information, it was designed with one core from Cluster 1 running at 2.30GHz, four cores from Cluster 2 running at 2.40GHz, one core from Cluster 3 running at 2.78GHz, and four cores from Cluster 4 having the highest clock speed of 2.88GHz.The new leakage of 4.2GHz speed is much faster than the above benchmark speeds.Development reportedly progressing smoothlyThis latest leak comes after remarks made by Samsung System LSI Business about their chip development.As per a recent report, Park Yong-In, the President of Samsung's System LSI Business, while giving an internal briefing at the company, revealed that development for the next generation mobile processor Exynos 2700 is already underway. The executive was quoted as saying that the development process is "going without any problems."
