The latest news about AMD Radeon R9 300 Series is orienting from the foreign media chiphell. One of the forum user has shared the 3D Mark 11 Extreme Score of AMD Radeon R9 300 graphics card which is most probably R9 390X. The Graphic card from AMD next-Gen camp has allegedly obtained 8121 points. The current single-core High-End Graphics card AMD Radeon R9 290X obtained 4611 points and on the other side GTX 980 scored 5735 points. So the counted performance of R9 390X in comparison with the current Single-core High-End Graphics card boost upto 50-60%. Really too exaggerated, may be the use of HBM memory is the reason behind such massive results.

The pervious news coming from the an unconventional source confirmed the use of HBM in 300W Graphics card. Leak comes from the LinkedIn profile of Linglan Zhang, Director of Systems Architecture at AMD and Physical Design Engineer at ASIC.

From the Zhang’s profile we have found the following:

hbm-01-600x260

New memory has a much higher bandwidth and lower power consumption with respect to the currently used GDDR5. If you refer to 300W TDP, we suspect that AMD Radeon R9 390X was that top model. Is weaker models will also be equipped with a memory HBM? That, unfortunately we don’t know about this case, but the result we have seen from the above shots are amazing. Lets wait and see when AMD will release the rabbit from their hat.
