Sapphire R7 370 Nitro Testing:

Finding out how the Sapphire Technology R7 370 Nitro performs 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 be testing the cards at their stock speeds to see how they stack up and will test each one to find the maximum stable overclock. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. A resolution of 1920 x 1080 will be used for the performance measurements.

 

Testing Setup:

Comparison Video Cards:

  • ASUS R9 270 Direct CU II
  • Sapphire R7 370 Nitro
  • ASUS GTX 950 Strix
  • MSI GTX 950 Gaming
  • EVGA GTX 950 SSC

 

 

Overclocking:

  • Sapphire R7 370 Nitro: Core 1050MHz, Memory 1495MHz

Sapphire's R7 370 Nitro comes with modest clock speeds of 985MHz on the Pitcairn style core and 1400MHz, or 5600MHz effective, on the 4GB of GDDR5 memory. At these speeds, there is some more meat left on the table for the overclocker looking for a bit more FPS. One thing I found up front is during some of the tests and games the applied overclock would simply not apply, yet in others the overclock would apply as soon as the driver sensed a 3D load. It is most likely a driver related problem as it manifested itself on the 15.5 beta and 15.7 driver used for this review.

That being said, in the games where the overclock applied there was an increase in performance. Without the ability to bump the voltage to the core, I had to manage the current flow to the card by using the power limit. Depending on how aggressive you are with it, you can throttle the clock speed when applying this setting. By sticking at +16%, I was able to keep the core clock speed at 1050MHz throughout my testing; a 65MHz increase that adds up to a core clock increase of around 6.5%.

Overclocking the memory yielded a more generous 95MHz for a final clock speed of 1495MHz, or roughly the same 6.5% boost in speed seen on the core. To make sure this speed stayed stable, I adjusted the fan speed to 100% and in the process welcomed more than reasonable temperatures. There is a little bit of core clock available, but you will need to fight for it and do the detailed testing to make sure the clock speed you apply sticks in each game.

 

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.
