Results: Tomb Raider And Metro: Last Light
While we're able to run Tomb Raider at 1920x1080 using on-die graphics, we had to drop the quality settings as low as they go (except for keeping FXAA and 8x AF turned on).
Again, we see that HD Graphics 2500 aren't viable in a 3D workload like this. Also again, there's plenty of data in Chris' Core i7-4770K review to show that neither HD Graphics 4000 or HD Graphics 4600 can overtake A10-5800K. So, A10-6800K is probably safe unless Intel decides to enable its GT3/GT3e configuration on the desktop. The company currently has no plans to do this.
Mapping frame rates out over time simply gives us a little extra detail.
Although the variance between subsequent frames appears low in general, we found this title to suffer from noticeable stuttering. Perhaps it was simply a result of lower overall frame rates giving the perception of less-smooth performance.
Metro: Last Light is easily the most demanding title in our suite, requiring us to drop the graphics details to their lowest settings and dial the resolution back to 1280x720. Fortunately, the game still looks good at those settings.
A demanding benchmark sequence pushes frame rates under 20 at times, despite decent averages from the A10 APUs. The discrete Radeon HD 6670 doesn't do any better, and Intel's HD Graphics 2500 isn't viable at all.
As you can see, the APUs manage to maintain frame rates in excess of 30 for much of the test, but are pushed under 20 FPS in several cases. It's tempting to say that you'll see better real-world performance from this title, though we know taxing sequences like the built-in benchmark are when gamers most commonly decry the inability of their hardware to perform.
Variance between subsequent frames isn't bad, but we simply cannot get around the fact that the experience in this title suffers from frame rates that are simply low.
