New audit the Polaris AMD chips use less energy


Currently, the engineers Radeon Technologies Group (a division of AMD) is a difficult choice: continue to work to improve Polaris Polaris 10 and 11 energy efficiency of GPUs or to throw all their forces to develop GPU Vega. According to the resource WCCFtech before the advent of high-end chip solutions to Vega and 10 mid-level graphics cards based on Vega 11 we are waiting for the release of new revisions Polaris 10/11 with significantly lower power consumption than that ” summer »GPU.

the Polaris 10

The foreign colleagues believe that the baptism of the new chip revision will be the actual issue (and not “paper” announcement ) Radeon E9550 graphics cards and Radeon E9260. The first is an analog model Radeon RX 480 graphics adapter and consumes only 95 watts, and the second – an analogue Radeon RX 460, is also not too demanding to power (50 watts). It is noted that Radeon E9260 not only more economical third table RX 460, but operates at a higher frequency in the boost-mode – 1.4 GHz compared to 1.2 GHz, which in turn significantly affects the “clean” performance ( 2.5 teraflops against 2.15 teraflops in FP32-calculations).

The emergence of new revisions the GPU 10 Polaris and Polaris 11 in the consumer segment will occur first in the segment of mobile PC, where every watt important. Fruits of “growing up” 14-nm process technology Samsung / GlobalFoundries, apparently overshadowed the old 28-nm graphics cards on chips Antigua (Tonga) and Strato (Bonaire).

Prior to energy-efficient desktop counterparts Radeon RX 480/470/460 will get the least. Depending on what tactics will choose AMD – a decrease in energy consumption without altering the frequency or increase performance while preserving TDP-rated – we will witness the release of a «green» Radeon RX (eg, with a prefix LP – Low Power), or something like Radeon RX 485/475/465 . In the second case, by the way, should be useful crystals Polaris 11 with all 16 multiprocessor clusters comprising a total of 1024 stream processors, 64 texture units (TMU), 16 rendering units (ROP) and 128-bit memory bus.

“Second Youth» Polaris 10 and Polaris 11 will cost AMD is not cheap, but at the same time fans of the brand Radeon happy experience in a new video card, and there are already to Vega 10/11 at hand …
