ASUS R9 280X DirectCU II TOP & R9 270 DirectCU II OC Testing:
As GPUs become more capable of pushing higher pixel densities, the use of panels supporting ever higher resolutions are hitting the market with prices dropping as better technology hits the market. Monitors supporting resolutions up to 4K are available, but can be pricey depending on the screen size you are looking for. If you look at some of the non-name branded parts, you can find some tremendous bargains at the 2560x1440 resolution and even find some deals on Ultra HD televisions that can be had as low as $700. I will be running six games through the UHD testing to see just what each card will do with high settings and reduced anti-aliasing levels. The test setup is the same as the one used for the balance of the GPU Testing with the exception of the switch to an ASUS PQ321Q 4K capable panel. The settings used for each game can be seen in OCC's 4K testing article.
Setting up the FCAT tools to be able to measure the output signal to the display creates some challenges in measuring the raw data just due to the screen size and is more along the lines of measuring the results when running a 5760x1080 resolution. You can take a look back at our introduction to FCAT for a more in-depth look at the technology and hardware required to pull these results. While FRAPS is a valid measurement for what it does, it does not give an accurate picture of what is actually hitting the screen. For that reason we choose to stay with FCAT as our method for capturing FPS and illustrating anomalies in performance from one manufacturer to the other. To capture the data stream going to the PQ321Q, the setup is a bit different than capturing the data at lower resolutions. Since we basically have a two-monitor setup with the UHD panel, we can hook up the hardware-based capture solution as indicated below to keep the data stream at a manageable level.

Comparing the performance of ASUS' R9 280X DirectCU II TOP to that of the Sapphire Toxic Edition R9 280X, shows that the clock speed differences between these two cards defines FPS performance at a resolution of 3840 x 2160. Depending on the game, the R9 280X DirectCU II TOP FPS results are either comparable or slightly lower.
