Today Intel shared some information on the graphics capabilities and IGP model names for Haswell, which will launch a month from now.
Dubbed “Iris Graphics”, there will be many models across desktop and mobile markets, and performance varies wildly between them. In fact, there are so many CPU and GPU SKUs that it might be hard to keep track of it all – this is nothing new for either CPU manufacturer of course.
On the PC side (which includes mobile), you have GT1, GT2, and three variants of GT3. GT1, 2, and the 15W version of 3 will still be referred to as “Intel HD Graphics” while the full power version of GT3, and the eDRAM version of GT3e will wear the Iris and Iris Pro monikers.
Where exactly all these models will sit, we aren’t 100% sure yet, because the full Haswell 4th Gen Core lineup has yet to be officially announced. However, Intel did share some performance results, using the real components that will be released next month:
This graph details the 4770K which presumably will directly replace current top Ivy Bridge part 3770K. What about the 4770R, which is even faster? We can only speculate now, since nothing is official yet, but it most likely refers to the highest end BGA (socketless) version that scared everyone when it was first discovered. Interestingly, Intel is saving the best GPU performance for these all-in-one systems.
So for us, the component you’ll want to pay attention to is the 4770K, which boasts around 1.75X the performance of 3770K and its HD Graphics 4000 IGP in 3DMark 11.
That combo scores around 800 in 3DMark 11, which puts the 4770K at around 1400 or so. This puts it well within reach of the current top dog IGP, AMD’s Trinity A10 5800K, which scores around 1500 in 3DMark 11. Now the 4770K will likely be well over twice the price of the A10 5800K, but its CPU performance and power consumption is expected to be significantly better.
This is all based on one score of course; we won’t know the full story until we get one in house, and test it with real games, using frame time measurements. But if Iris can perform as well as Trinity, Intel may have finally reached the point where its integrated graphics solution is viable for 720p gaming. It’s just too bad that the real gaming solution will only be available as an all-in-one solution.
