According to the latest report it appears that upcoming Ellesmere and Baffin Polaris GPUs might not be as fast as we actually expected but should do well in the performance and mainstream market segments due to their high power efficiency.

According to a latest report from Techpowerup.com, citing industry sources, the upcoming Polaris GPUs based on AMD's 4th generation Graphics Core Next architecture will mostly cover performance and mainstream market segments.

The larger chip, Ellesmere, could feature 32 Compute Units (CUs) and not 40 as rumored earlier, adding up to a total of 2048 Stream Processors, if CU consists of 64 Stream Processors (SPs). Further details suggest that it packs around 5.5 TFLOPs of single-precision compute performance which is higher than Hawaii-based GPU with 2816 Stream Processors, making it significantly faster.

According to the report, the TDP of the larger Ellesmere GPU should not be higher than 150W, which is a significant improvement over 250W on the Hawaii-based graphics cards, which will allow AMD to make a graphics cards with a single 8-pin PCI-Express power connector.

The rest of the specifications will include 256-bit memory interface and 8GB of GDDR5 or GDDR5X memory with first SKUs featuring 7Gbps GDDR5 memory.

The smaller Polaris chip, aka Baffin, could pack only 14 CUs, which adds up to 896 Stream Processors. This chip should replace AMD's Tobago-based Radeon R7 360 graphics card but could offer performance of a Trinidad-based R7 370. With single-precision compute performance of 2.5 TFLOPs and 50W TDP, it should be a good mainstream graphics card.

According to the same report, graphics card with smaller Polaris-based Baffin GPU could end up with 4GB of GDDR5 memory and a 128-bit memory interface.

Hopefully we will hear more about upcoming Polaris-based SKUs at either a dedicated event ahead of Computex 2016 or at least during Computex 2016 show.
