[Major issue] R7 370 yields 133 FPS in Tesseract, while R9 285<br>
unexpectedly yields 111.81 FPS in Tesseract<br>
<br>
R7 370: 1996.8 GFLOPS<br>
R9 285: 3290 GLOPS<br>
<br>
I would like this forum thread to identify the cause of the major<br>
issue. So the question is:<br>
<br>
*** What might be causing R9 285 to perform worse than R7 370? ***<br>
<br>
(I don't have access to R7 370 nor R9 285. My current answer to the<br>
question is: I don't know.)<br>
