AMD Radeon R9 M295X gets benchmarked in Apple iMac 5K

Apple recently announced their all-new 27-inch iMac which comes with rather impressive 5K display having mind boggling 5,120 x 2,880 pixels. The new iMac comes with the yet-to-be-released AMD Radeon R9 M295X graphics chip as an option. One thing is clear that the GPU must be powerful enough to be selected to drive Apple’s 5K iMac but we are yet to see some real benchmarks of this new graphics chip. However, a YouTuber, Danny Winget, got a full spec’d iMac 5K which comes with the R9 M295X and put it to test.

Even though the YouTuber was not really interested in depicting the raw performance of the GPU used in the iMac however he did run the OpenGL test of CineBench R15 which gives a fair idea about graphics card’s performance. However, since this particular version of CineBench is not widely used so we don’t have other data points to compare the results of R9 M295X but we found results of GeForce GTX 770 and GeForce GTX 780M which can be compared to the results taken from the iMac review video.

According to the video, the iMac 5K with R9 M295X managed to score 105.63 FPS in the CineBench OpenGL test whereas the GTX 770 scores 98.78 FPS and the GTX 780M scores 92.59 FPS in the same test. It is quite impressive that the R9 M295X has beaten the GTX 770 which is a high performance desktop graphics card from last generation as well as the GTX 780M which is flagship mobile graphics card from last generation. We would still hold out to make final judgements until some detailed reviews of R9 M295X surface but for now, it has not failed to impress.

The Radeon R9 M295X is, reportedly, based on Tonga XT architecture and comes packing 2048 stream processors. It has 800 MHz core clock along with 4GB of GDDR5 memory running at 1375 MHz on a 256-bit wide interface.
