Notes
We have nine of the best IGP-enabled CPUs from current and recent generations prepared for our comparison. All have been tested from the grounds up on Windows 8 using the latest drivers, providing a generational overview between Trinity and Richland (AMD) and Sandy Bridge, Ivy Bridge and Haswell (Intel).
Intel processors tend to be dearer than AMD's APUs - for example, the Core i7-4770K commands a retail price of £270 while the A10-6800K just £110. We have thus also included a third-generation Core i3-3225 into the mix, costing the same £110, though would have chosen a fourth-generation Haswell chip if a price-comparable model had been available. The two price-equivalent chips have been highlighted in the ensuing graphs.
Aside from required motherboard changes, all platforms were tested using the same hardware and reference coolers, though please note that the AMD A10-5700 and Intel Core i3-3225 had to be run with memory reduced to 1,866MHz - they simply wouldn't boot with the G.Skill RAM set to its default XMP profile of 2,133MHz.
