Onboard GPU Performance
We can’t discount the built in GPU as well, especially with the new Iris 6200 GPU seeing the biggest improvements in the move to Broadwell. So I did run the i7-5775C through our benchmark suite and along with that I have added a few new tests as well. To start off my testing I ran the 5775C in Cinebench R11.5 and R15. This time testing using the OpenCL setting to test the graphics performance rather than compute performance. The results are the average FPS that it was capable of rendering a video. As you can see the 5775C dominated in this test. Not only did it out perform the i7-4790K, but it also put over 20 FPS on the AMD A10-7850K when it was paired with a matching dedicated GPU for crossfire.
Next I ran it through 3DMark Fire Strike on the performance setting. This time around it didn’t outperformed the crossfired AMD but it put 300+ points on the next closest CPU. For comparison this is closer to what you would expect from an HD 7750 or similar, they aren’t exactly replacing dedicated GPUs here, but the performance is finally reaching a point where you can trust it in most games with things turns down where in the past onboard could only play a few Facebook games.
Next I ran through both the older Unigine Heaven Benchmark 4.0 as well as the Valley 1.0 benchmark as well. I still consider these to be synthetic benchmarks because they aren’t a specific game, but being based on the Unigine engine they are a great way to see how the 5775C will perform in Unigine based games. It’s no surprise that once again it topped the charts, even against the CPU paired with a dedicated GPU. The FPS numbers aren’t all that impressive because these tests are run on the Extreme and Extreme HD settings for easy duplication, but with the performance doubling over pervious Intel designs I am impressed.
F1 2013 is a little dated, especially now that they just released F1 2015 but it is still a great benchmark to compare the performance between all of the onboard GPUs. It is known for being a little AMD favored when compared to Nvidia cards so it’s no surprise that the A10-7850K pulled ahead here a little more than in previous benchmarks. A small win for Intel though is to finally be able to say this game is completely playable where past CPUs were struggling.
In Bioshock Intel went from a rough 15 FPS on the i7-4790K to a more than playable 37 FPS on the i7-5775C that gave the 7850K with the R7 250 in crossfire a run for its money.
The same happened in Tomb Raider as well with the crossfired setup and the 5775C well above everything else and well into the playable range as well. This is of course tested at a medium setting, but it is still a great game that I would never think could be played on an onboard GPU.
In Hitman the 5775C struggled a little. It still out performed every other onboard GPU but it didn’t pull the huge lead that they had in most of the other tests. That said when you keep in mind the jump to 15FPS from 6-7FPS it is an amazing improvement over the Haswell CPUs.
In Sleeping Dogs the i7-5775C is once again well ahead of all of the other onboard GPUs with a respectable 43 FPS.
I also included my results from GRID Autosports where I ran the benchmark at both Medium and Ultra settings. Clearly ultra isn’t ideal for the i7-5775C but the medium settings put us right up close to 60 FPS in a new game and frankly even at medium settings the game looks great.
