The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14CPUPro]
The A10-5800K features integrated Radeon 7660D graphics which are approximately 10% more powerful than the HD 4600 graphics found on several of Intel's Haswell CPUs. With its four cores the A10-5800K is able to handle multi-core workloads reasonably well but it is far less able to handle single and dual-core tasks. Comparing the i3-4130 and the A10-5800K shows that the i3-4130 is approximately 20% better at handling single and dual core workloads. Single core speed is by far the most important requirement for general desktop computing. Overall the A10-5800K provides an all in one solution with relatively strong integrated graphics but there are better performing alternatives available for the same money. [Mar '14CPUPro]
