Reviews

The Radeon R7 series

AMD Radeon R7 260X

AMD-Radeon-R7-260X-Specifications
Just as I reported earlier, the 260X is a HD 7790 rebrand. It packs a Bonaire GPU with 896 Stream Processors, 56 Texture Mapping units and 16 ROPs. By default it comes with 2GB GDDR5 memory with a 128-bit interface. Card is clocked at 1100 MHz and 6500 MHz for core and memory respectively. This model is now available for $139.

AMD Radeon R7 250

The 250 is equipped with an Oland XT GPU, which has 384 cores. The card is clocked at 1000/1050 MHz making it quite fast in comparison to 240. The R7 250 has 1GB or 2GB memory depending whether you prefer GDDR5 or DDR3 modules. The R7 250 is now available for $89.

AMD Radeon R7 240

AMD-Radeon-R7-240-Specifications
The slower variant of the Oland GPU (PRO) packs less cores — at 320. It’s also clocked lower than the 250 — at 780 MHz with boost. This card is available in at least four variants, all differing in memory configuration – you may choose up to 4GB memory. The cheapest R7 graphics model is now available for $59.

The Radeon R9 series

 

AMD Radeon R9 270X

AMD-Radeon-R9-270X-Specifications
Equipped with the Curacao XT, the R9 270X will offer 1280 Stream Processors, 80 Texture Units and 32 ROPs. You can get it with 2GB GDDR5 memory across a 256-bit interface. This card is clocked at 1050 MHz for core and 5600 MHz for the memory.

AMD Radeon R9 280X

AMD-Radeon-R9-280X-Specifications
Currently the fastest R9 graphics card is obviously the 280X, a HD 7970 rebrand. It packs a Tahiti GPU with 2048 Stream Processors, 128 TMUs and 32 ROPs. The clock depends on the manufacturer, but according to the official slide it should oscillate around 1GHz. Even the TDP has not been changed dramatically — 250W.

According to Anandtech, you will be able to connect both HD 7970 and R9 280X in CrossFire, so if you were going to replace your Tahiti card then there is no need. Additionally it is said that AMD will no longer advertise base clock specifications. This is quite disappointing and seems misleading, but maybe AMD will explain their decision to do so soon.
