Its an AMD Quad-Core A10-8700P APU with Radeon™ R6 Graphics. From reviews processor is similar in speed to i5 but the graphics card allows some game usage.
Some reports of WifI issues but bios/intel driver reported to have solved this.
Was looking for i5 laptop for my daughter but figured this was comparable to the £300 models advertised but with better build quality.
