PowerColor Radeon R9 295X2: High-End Adapter with Two GPUs

PowerColor has recently launched the most powerful in AMD’s Radeon series graphics card, entitled Radeon R9 295X2. The key peculiarity of the model is the availability of two GPUs, which are accompanied by a hybrid cooling system. Such remarkable specifications make the card an ideal solution for advanced gamers and overclocking enthusiasts.



PowerColor Radeon R9 295X2 employs PCI-e 3.0 x16 interface and incorporates a pair of AMD Hawaii XT GPUs (28 nm, GCN 2.0). Each processor features 2816 CUDA cores, 64 ROPs, and 176 TMUs. They operate at the maximal 1018 MHz clock frequency. Each GPU ‘cooperates’ with 4 GB GDDR5 memory (8 GB in total) with 512-bit rails. Its nominal clock frequency makes up 1250 MHz, whereas efficient frequency might reach up 5000 MHz.


This remarkable graphics card is furnished with a hybrid cooler. Both GPUs are taken care by a liquid-cooling solution of enclosed type, power circuits are taken care by air cooling. The latter consists of a fan …

Intel Claims Its Clover Trail More Efficient than Tegra 3

The stonewall in the tablet and mobile CPU segment is gradually mounting, with Intel and Nvidia increasing their influence and rivalry. Hence, Intel's developers claim that its latest tablet processor, two-core Atom Clover Trail, surpasses Nvidia's Tegra 3 in both performance and power consumption. To be precise, Clover Trail proves to be more efficient in a range of applications, but at the same time, it consumes power twice less than its counterpart. To exemplify such claims, Intel takes Imagination Technologies graphics that consumes less power than Tegra 3.



Numerous testing results conducted by Intel and some leading IT analysts demonstrate that Tegra 3 with four main cores and one additional core is slower that Clover Trail. Testing of performance and power consumption has been held on Microsoft Surface RT with Tegra 3 chip and Windows 8 tablet with Clover Trail chip. Nevertheless, Intel hasn't conducted any comparison in mobile OS from Google.

Asus to Start Shipping Radeon R9 290 DirectCU II OC Graphics Card

Next week Asus is going to start shipping its newest graphics card from Radeon R9 series. Codenamed Radeon R9 290 DirectCU II OC, it is based on an original PCB with black-and-red design and the incorporation of an exclusive DirectCU II cooling system. Plus, the availability of ‘OC’ in the codename implies the availability of factory overclocking.



Asus Radeon R9 290 DirectCU II OC takes GCN Hawaii core with 2816 stream processors as the basis. It operates at an overclocked 1000 MHz frequency. The model is equipped with 4 GB of GDDR5 memory (512-bit bus) that runs at an effective 5400 MHz frequency. Just for a comparison, etalon adapter from AMD runs at 947 MHz/ 5000 MHz for GPU/memory correspondingly.


DirectCU II cooler consists of a heatsink, four copper nickel-plated heatpipes (two of them feature 10 mm dimensions), and two high-performance fans: one ordinary and one CoolTech. The card receives power via 6+8-pin connectors and might require not less than 600 W PSU.
