On the day of the long awaited launch of the Radeon RX series we can finally talk about the specifications of the new GPU Polaris that have been the focus of a recent presentation. The RX 470 and RX 480, both united by the chip Polaris 10, respectively, with uncompromised 1080p and 1440p, all against a very good relationship between price and performance. The chip Polaris 10 of 470 approaches the 5TFLOP power with 32 compute units, from 4 to 8GB of GDDR5 memory, 224GB / s of bandwidth, auxiliary power connector 6-pin and the obvious FreeSync support. Instead the Radeon RX 480, designed to cope easily with the titles for Oculus Rift and HTC Lives, aiming higher, exceeding on paper 5.8TFLOP with 150W TDP, 36 compute units, from 224GB to 256GB / s bandwidth , up to 1266MHz for the core clock in boost and up to 8Gpbs as regards GDDR5 memory.
Unfortunately AMD did not comment about several details that we are required, pending the complete specifications that will come no doubt starting today, to fill the gaps with the rumors that speak of 2304 stream processors for the RX 480 and 2048 for RX 470. apparently the RX 480, now available in 4GB and 8GB versions, will be available in several models, more or less bold, but everyone should be able to get about 1500MHz overclock with only the auxiliary connector 6 pin and without modifications. To go further you will need to look at custom equipped with auxiliary connector 8-pin or two connectors that promise to fully exploit the advantages in terms of consumption and implicit in the use temperatures of the manufacturing process to 14 nanometers.
AMD has also made mention of the Radeon RX 460, the low-end solution that is based on the chip Polaris 11 and has been designed for eSport and free to play not too exorbitant. The specifications speak of 2TFLOPS of computing power, 16 compute units and 896 stream processors accompanied by 2 or 4GB of GDDR5 memory. Among other innovations, we find a more understandable nomenclature to facilitate the understanding of the hierarchy of models, support for DisplayPort 1.4 with HDR, 4K encode / decode for all RX and architecture designed to grow with the evolution of next generation libraries.
The evolution of GCN technology includes more asynchronous computing capabilities, enhanced priority management, a new controller for memory, more control over the allocation of resources dedicated to shaders, geometry engine perfomanti more and more colored delta compression, similar to NVIDIA Pascal, to reduce the load of data. According to information available, we can verify in the coming hours, the prices are expected to start by the RX 460 2GB $ 99 to get to the RX 480 $ 299 custom designed to achieve very high frequencies. With the changeover we can expect, in addition to the unavoidable increases of the first days, the classical conversion one by one with the addition of a good 20%. Ultimately we are talking about 110 Euros for the cheapest solution, approximately 145 for the RX 460 4GB, of at least 165 for the RX 470 4GB and nearly 200 for the 8GB. As for the RX 480 instead we can expect to pay € 220 for the 4GB version, 250/260 Euros for the reference Radeon RX 480 and 350 for custom pumped.
