Results: 3DMark And Aliens Vs. Predator
Although it's theoretically able to serve up playable frame rates across our entire benchmark suite (at the right resolution and settings, of course), AMD's Radeon HD 7660D integrated graphics processor wasn't designed to compete against the company's own discrete GPUs. That usually means choosing between higher graphics quality or resolutions.
In 3DMark, the limitations of integrated graphics mean using the Entry preset. And as you can see, memory bandwidth has a big impact on this synthetic's overall score.
Stepping up to 3DMark’s Performance preset generally imposed a slide show upon us. Nevertheless, the terrible frame rate was still sped up slightly by faster system memory.
We're putting Aliens Vs. Predator on the same page as 3DMark, since I'm using the benchmark version of this utility. It's still based on a real game though, so we're including the numbers from this one in our overall gaming performance chart.
AvP exhibits huge performance gains favoring higher memory data rates at the most entry-level settings. Unfortunately, those image quality presets look pretty awful compared to other, more modern titles.
Still devoid of luscious graphics, but with far fewer jagged edges, enabling anti-aliasing and anisotropic filtering in AvP knocks AMD's APU to its knees. We get playable performance at 1280x720, but you'll probably want at least DDR3-1866 to help performance as much as possible.
The question is ... does the performance with higher speed memory continue to scale as the *SIMD Engine Array* is over-clocked.
Inquiring minds would like to know ...
Individuals who would use faster memory for gaming are likely to want to push their mid/high range card to the limits, do you plan on doing a similar piece for AMD CPUs as you did in the Intel article "Does Memory Performance Bottleneck Your Games?"
Also, I would like to see a Nvidia card at play as well. Maybe a 650 Ti or 660 Ti? In addition, it wold be nice to see the memory scaling difference between AMD and Nvidia GPUs in a single review.
It's back to looking at better GPUs and CPUs for better performance.
Bpttleneck hierarchy has always been GPU>CPU>RAM.
The CPU has always been more reliant on the RAM than the GPU but an APU is basically a GPU+CPU in one, so RAM is more important, but as we've seen, only up to DDR3-2133. After that diminishing returns skyrocket.
The more you know... /rollseyes/
still, 15 gb/s out of ddr3 2400 ram is just sad. i expect amd to improve in the next gen apus. the igpus deserve the extra memory bandwidth.
i wonder how cpu overclocking (along with igpu and ram oc) affect the games like skyrim, starcraft and f1. those seemed more memory sensitive.
