XFX R7 240 Core Testing:
Testing of the XFX R7 240 Core will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.
The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The NVIDIA comparison cards will be using the 330.58 drivers while AMD-based cards will be using the Catalyst 13.11 beta drivers.

- XFX R7 240 Core: Core 1015MHz, Memory 1300MHz
The memory overclock results were incredible; I expected to hit a ceiling much sooner. Pushing much further than this rate would cause instability. Everything was stable throughout testing, I had wondered if some form of ECC was aiding overclocking — multiple tests showed increases of scores even with the clock rates. XFX under-clocked the memory and there is the higher speed IC H5TQ2G63BFR-12C rated for 1000MHz. Maybe it is just a very good bin, the memory timings could be loose, and memory voltage could also be factors. Nonetheless the big boost of memory bandwidth really helped waken this little card up along with a 235MHz core overclock over the Boost speeds. To sum it up, the core speed increased over 30% over Boost speeds and memory 62.5%! The R7 250 reviewed before is the fully unlocked Oland XT core with six compute units, and 1GB GDDR5 memory with more bandwidth. Oddly, the XFX Oland-based graphics cards can only be had with either 1GB of GDDR5 or 1-4GB of DDR3. With the overclock settings it will be neat to see how the XFX R7 240 Core stacks up in comparison to the other cards.
Maximum Clock Speeds:
Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for thirty minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were re-run until they passed a full hour of testing.
