AMD Radeon R9 285: the Radeon R9 285 is based on a new Tonga GPU. Its still built on the 28nm node from Global Foundries and features bit of a re-design applying the latest architectural improvements. A big focus of the Tonga GPU is actually power efficiency. Tonga retains the basic technologies of the Radeon lineup such as Mantle, TrueAudio and XDMA for CrossFire support. The GPU actually has 2048 shader processors running over 32 compute units with 128 texture memory units. The initial consumer graphics card based on Tonga now is the Radeon R9 285, it has 1792 activated stream processors making it perform at GeForce GTX 760 and Radeon HD 7970 level performance levels but with better thermals and lower power consumption. Performance wise this product is going to sit in-between the 280 and 280X. Most of the cards will have two 6-pin power PEG (PCI Express Graphics) headers to give the tweaking experience a little more room next to the 4+2 PWM phase power design. Overall a great card to play the latest games with whilst offering a good memory size versus good price versus the Full HD / 1080P monitor resolution. The R9 285 is armed with 2 GB @ 5.5 Gbps / 256-bit to get you a little more leash with resolutions and image quality settings. The reference clocked products will run with clock freqeuncy up-to 918 MHz on its 1792 shader processors. The card has been designed to be a nice match for Full HD gaming, up-to 1080P. AMD however is positioning the card as a great alternative for 2560x1440 gaming, The specs are fairly similar to the regular 280, 1792 shader processor running up-to a core frequency of 918 MHz. The 2 GB GDDR5 graphics memory runs on a 256-bit wide bus. R9 285 (Tonga) Stream Processors 1792 Clock Frequency up-to 918 MHz 3.29 TFLOPS compute performance 2 GB memory at 5.5 Gbps / 256-bit 190W TDP PCI-E 3.0 API - DirectX 12 / OpenGL 4.3 / Mantle
