XFX R7 250 Ghost 2.0 Testing:

Testing of the XFX R7 250 Ghost 2.0 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.

Overclocking:

  • XFX R7 250 Ghost 2.0 : Core 1125MHz, Memory 1300MHz

With this new architecture I didn't know what to expect with overclocking. I had some guesses — quickly finding out that this card would go quite high! Voltage control is not unlocked with any software that I tried, so I set power limit to +20, and with stock voltage I managed 1125MHz on the core. The default core speed is 1000MHz with 1050MHz boost speed. That is an easy 12.5% increase in a few minutes versus stock (non-Boost) speed. The memory was 1125MHz stock (4.5GHz effectively) and without any voltage increases was able to climb to 1300MHz (5200GHz effectively). That is an increase of roughly 15.5% over stock speeds.

Using MSI Afterburner with unofficial overclocking allowed me to push the card higher than the AMD-imposed maximums. As with other graphics cards overclock settings the fan speed was set to 100% where applicable (the R7 240 was fan-less). Temperatures were only slightly affected and stability wasn't a problem unless clocks were pushed much further than these settings. Testing with these overclocked speeds was completely stable.

 

Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for 30 minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were rerun until they passed a full hour of testing.
