IGP Performance
As we suspected, the extra 4 EUs of the Intel HD 4600 Graphics don't make it much faster than what we already had with the HD 4000 Graphics. The 25% increase in EUs and the slight bump in operating frequency allowed for 27% more performance in Medal of Honor Warfighter at 1440x900.
However even at this modest resolution using medium quality settings the HD 4600 Graphics only spat out 21.8fps, which is still slower than AMD's flagship APU. Even when compared to two and a half year old low-end discrete GPUs this is very poor performance. The Radeon HD 6750 for example provided twice as much performance.
Meanwhile current generation low-end graphics cards such as the Radeon HD 7770 and GeForce GTX 650 Ti retail for around $100 and provide 3 - 4x more performance.
Metro Last Light is the perfect example of how a modern video game will run on these integrated solutions using relatively low-resolutions and in-game quality settings. Again the Intel HD 4600 Graphics was slower than the Radeon HD 7660D of the AMD A10-5800K.
Max Payne 3 is very playable on low-end discrete graphics cards when using the medium quality settings, the Radeon HD 6750 (2.5 year old product) averaged 58.2fps at 1440x900. The Intel HD 4600 Graphics on the other hand couldn't provide half as much performance with just 24.5fps. The AMD A10-5800K was able to provide playable performance at 1440x900, albeit barely.
