AMD unveils Radeon RX 500 – faster and more efficient than RX 400 GPUs
At last! AMD revealed the new Radeon RX 500 graphics cards for which there were so many rumors. The latter were pretty accurate, the new GPUs are based on improved variants of the Polaris chips found in previous series – RX 400. The improvements are in terms of higher efficiency of the 14nm FinFET manufacturing process. This allows higher frequencies and lower energy consumption. Additionally, the RX 500 series will feature 4 GPUs which are expected to conquer the world of budget graphics cards.

The most powerful of these is Radeon RX 580 which is offered in variants with 4/8 GB GDDR5 and 256-bit graphics memory bus. The latter works at effective 8 GHz. RX 580, as well as its smaller sister RX 570, are based on a Polaris 20 chip, which is almost identical to Polaris 10 (to be found in RX 480). Additionally, RX 580 features 2304 stream processors positioned on 36 computing units, 144 TMU and 32 ROPs. You may wish to know that the core’s base frequency is 1257 MHz, while the boost frequency is 1340 MHz. On the other hand, the smaller RX 570 will come with 2048 stream processors, 32 computing units, 128 TMUs and 32 ROPs, while the frequencies will be a tad lower – 1168/1244 MHz base and boost speeds respectively. And the memory will work at a lower effective frequency as well – 7 GHz. Another similarity here is the options for either 4 or 8 GB GDDR5 memory.
Next on our list is RX 560 which is a direct successor to RX 460. The new model has 1024 stream processors and 16 computing units. Additionally, the operational frequency here is 1175 MHz and you can have 1275 MHz in boost mode. And the memory is operating at the same frequency as in the RX 570. It is realized on a 128-bit bus and has 4 GB of capacity. Two times less than that is the memory of the smallest GPU – RX 550. The chip, placed on the GPU, has 512 stream processors and 8 computing units. The GPU is ticking at up to 1183 MHz and is a low-budget alternative to integrated graphics cards.

By when can we expect these to be put into laptops? I heard the Lenovo Legion Y520 will have the RX560.
