Today Intel is releasing a number of new affordable Core i5 and Core i3 desktop processors, which are the first ever to include a built-in GPU. They are also the first processors to be manufactured using the 32nm design process making them even more efficient than existing products. So get ready as we show you exactly what they are all about...

The new Core i5 6xx and Core i3 5xx series of processors are now amongst the fastest dual-core processors money can buy. Even some quad-core processors fell victim to the Core i5 661, as it defeated the AMD Athlon II X4 620 in virtually every test. The AMD Phenom II X2 550 also struggled to keep pace with the Core i3 540 in most tests.
