The paper uses the Value Added Intellectual Coefficient VAIC^TM model, a widely used model to measure the Intellectual Capital efficiency of the banks within Gulf cooperation Council (GCC) using a 5  years period data set from 2007 to 2011. Three value efficiency indicators, Human Capital Efficiency (HCE), Capital Employed Efficiency (CEE) and VAIC^TM, where used in the analysis. The data set was divided into conventional and no-conventional (Islamic) banks. The results of the rankings of the GCC banks for the last two years (2010-2011) show that for VAIC^TM, which expresses the intellectual ability and indicates the value creation efficiency of all resources (the sum Capital Employed Efficiency indicator and Intellectual Capital Efficiency), the two top performers for conventional are Qatar National Bank followed by First Gulf Bank ( a UAE bank) and for the non-conventional ( Islamic) banks the two top performers are Masraf AlRayan ( a Qatari Bank) followed by AlRajhi Bank and Investment Company ( a Saudi bank).  However, the results of ranking based on Human Capital Efficiency (HCE), an indicator which measures how much VA is created on each monetary unit invested in HC, shows that  the two top performers for conventional are Commercial Bank of Kuwait followed by First Gulf Bank ( a UAE bank) and for the non-conventional ( Islamic) banks the two top performers are Masraf AlRayan  followed by AlRajhi Bank and Investment Company. And the ranking result based on Capital Employed Efficiency (CEE), an indicator which shows how much VA is created on each monetary unit invested in Capital Employed ( Physical and Financial), shows that  the two top performers for conventional are Oman housing Bank followed by Mashreq Bank ( a UAE bank) and for the non-conventional banks the two top performers are Qatar Islamic Bank followed by AlSalam Bank ( a Bahraini Bank).
