AMD reluctant to disclose information about the new generation of graphics cards from Polaris, but some of the information and so enters the network - the latest example is a partial specification Polaris models 10.
Editors from the Phoronix site, noticed, that the latest graphics drivers for Linux has changed the code marks (Device ID) данных конструкции – так вот последние значения были переименованы в Polaris 11, Ellesmere and has become a model Polaris 10. Drivers also revealed information about the memory subsystem – Polaris 11 a memory GDDR5 128-bit, а Polaris 10 GDDR5 256-bit.

A little later, it became clear, что в базе SiSoft уже есть устройство с маркировкой Device ID 67DF – зарегистрированное именно как Polaris 10. This design has been equipped with a graphics system 2304 stream processors (grouped into 36 CU blocks) and 8 GB GDDR5 memory, 256-bit, and the clock frequency is checked instance 800 MHz for the core and 6000 MHz for the video memory.
Раскрытая карта скорее всего является инженерным образом новой Radeon. However, it is not known, будет ли применено подобное ядро, It is quite possible that it was a stripped-down version, и непонятно какая память будет присутствовать GDDR5 или эффективная GDDR5X. Записи в драйверах предполагают также существование эффективной структуры, which could be based on the kernel with 40 The CU (2560 stream processors).

Теоретически производительность карты будет находиться между нынешними моделями Radeon R9 380X и Radeon R9 390. But it is worth remembering, it is based on the new architecture, which should provide significant performance gains – It may be so, that the theoretical worst spec, its performance will be better than the Radeon R9 390. That is the conclusion pushes demonstration of the potential of the accelerator in the game Hitman на конференции GDC 2016.
