Intel Apple Glen Test System Specs - Intel Core i3-2120 (3.30GHz) - x2 4GB G.Skill DDR3 PC3-10666 (CAS 9-9-9-24) - Intel DH61AG (Intel H61) - OCZ ZX Series 850w - Crucial m4 256GB Software - Microsoft Windows 7 Ultimate 64-bit - Intel Graphics Media Accelerator 15.22.50.2509 LGA1155 Test System Specs - Intel Core i7-2600K (3.30GHz) - Intel Core i3-2120 (3.30GHz) - x2 4GB G.Skill DDR3 PC3-12800 (CAS 8-8-8-20) - Asrock Z68 Extreme4 (Intel Z68) - Asrock Z68M-ITX/HT (Intel Z68) - OCZ ZX Series 850w - Crucial m4 256GB Software - Microsoft Windows 7 Ultimate 64-bit - Intel Graphics Media Accelerator 15.22.50.2509 AM3 Test System Specs - AMD Phenom II X6 1100T (3.30GHz) - x2 4GB G.Skill DDR3 PC3-12800 (CAS 8-8-8-20) - Asus Crosshair IV Extreme (AMD 890FX) - Gigabyte GeForce GTX 580 SOC (1536MB) - OCZ ZX Series 850w - Crucial m4 256GB Software - Microsoft Windows 7 Ultimate 64-bit - Nvidia Forceware 280.26 The Asrock Z68M-ITX/HT allows the Core i3-2120 to utilize DDR3-1600 memory whereas the Intel DH61AG limits the memory frequency to 1333MHz. As a result, the DH61AG saw a maximum read bandwidth of 16GB/s whereas the Z68M-ITX/HT reached 19.9GB/s – a 24% difference. Although the slower DDR3-1333 affects memory bandwidth performance, it has nothing to do with L2 cache performance. Unsurprisingly, the Core i3-2120 delivered similar results on both the Intel DH61AG and Asrock Z68M-ITX/HT.
