According to TechPowerUp, industry sources have informed some interesting specifications of the next two GPUs that AMD will launch the market, graphic Polaris 10 Polaris 11 , both based on the fourth generation of graphics architecture Graphics Core Next.
Although this leak comes first hand from one of the most important sites worldwide hardware must catch it with tweezers, as always, for there is nothing confirmed by the manufacturer. According to report, and we already knew, AMD is preparing two GPUs, one for midrange and one for the so-called industry performance (not high-end, eye).
Ellesmere GPU performance will be the sector and will according to the source with 32 CUs (Compute Units) and not 40 as previously thought. Assuming that each CU has 64 Stream Processors, this gives us that AMD graphics Polaris “Ellesmere” will have 2048 Stream Processors, yet these graphs have a power of 5.5 TFlop / s according to AMD.
While Hawaii AMD graphics have a TDP of no less than 250 watts, the new chips will have as much a TDP of 150 watts, which would allow AMD to put a single power connector 8-pin, as it has done NVIDIA its new generation, and as it did already in the R9 Nano AMD. According to the source, these graphic Polaris will have 8GB of GDDR5 / GDDR5X memory with a 256-bit bus, something we already knew well.
The “small” Polaris chip as techpowerup says, the midrange is called Baffin (as I have explained above). In this case count, according to the source, with only 14 CUs, ie, 896 Stream Processors nothing else. It would be the successor chip Tobago (Radeon R7 360) and a similar performance to R9 380 is expected, more or less. The good part of these graphs is that in theory will have a TDP of only 50 watts and will not need additional power connector.
