Sony Vegas 12 Rendering
In Vegas Pro 12, we rendered three tests. The 720p and 1080p tests were with Sony's Benchmark files, and the Custom test is with our own video that uses transitions but no special FX. We performed three tests: CPU only render, CPU + onboard graphics, and CPU + the VisionTek R9 290.
Looking at our custom test first, the CPU only render took 988 seconds to complete. The CPU, an Intel Core i7-4770K, and its onboard GPU took just 463 seconds, and the CPU with the VisionTek R9 290 took just 449 seconds. Very basic video at 1080P does not show a significant improvement with the additional card.
Graphics intensive videos with heavy transitions, special FX, audio, and other accelerated functions are another story. The 720p and 1080p tests show nearly identical times regardless of the acceleration used, but here we see that the VisionTek R9 290 cuts through the FX and renders the video in less than half of the time. Even with the onboard GPU used to accelerate rendering time, the difference between CPU only and CPU + onboard GPU is very small.
Sony Vegas 13 Rendering
Now we're moving onto Vegas Pro 13, this time with an additional test at 4K. Here we see the VisionTek accelerated rendering of our basic video actually going much quicker than the CPU + onboard GPU. If your system only has a CPU in it, then adding an R9 290 will cut the render time nearly in half, even on a very basic video with a few transitions.
The same basic video, this time rendered in 4K, also shows a significant improvement in render times. For our custom and 4K test, we really wanted to show what it would be like for a novice video, something from your family that you might share or upload to YouTube.
Vegas Pro 13 takes greater advantage of our R9 290 GPU than Vegas Pro 12. In the professional tests at 720p and 1080p, the GPU assisted tests take even less time than before, and the R9 290 is a clear winner, besting the CPU + onboard GPU by nearly three times.
