PowerColor Outs an Overclocked Radeon R9 270 OC Graphics Card

Along with other AMD partners, PowerColor has elaborated its own version of Radeon R9 270 adapter. The PowerColor Radeon R9 270 OC is differentiated from rival products by an improved cooling system and factory overclocked frequencies. Its release is scheduled for late November and the retail price won’t hit over $180.



To begin with, this graphics card is naturally based on AMD Curacao Pro GPU, developed under 28 nm technological process. It consists of 1280 current processors, 32 ROPs and 64 TMUs. The core runs at 930 MHz frequency and is able to gain 955 MHz frequency on overclocking. The incorporation of GDDR5 memory (2 GB) with 256-bit bus interface ensures some striking bandwidth of 180 Gb/sec; this provides for the support of gaming applications with high resolution. Memory chip operates at 1400 MHz nominal frequency but might gain the index of 5600 MHz of effective frequency on overclocking.

AMD Officially Introduces Radeon HD 7790 Graphics Card

An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.



Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD …

Sapphire Outs Nitro Series of Gaming Videocards

Sapphire is about to launch a new series of gaming graphics cards, entitled Nitro. The family counts three models: Nitro R7 370 4G D5, Nitro R9 380 4G D5 and Nitro R9 390 8G D5. Since the models take different GPUs as the basis, they are targeted diverse market segments, taking into account as budget-oriented gamers so spendthrift enthusiasts.



Sapphire Nitro videocards are distinguished by two major features. First of all, they employ a top-notch hardware base consisting of solid-state capacitors and Black Diamond ferrite chokes. Second of all, their cooling system boasts the implementation of a molten heatsink, supplemented by a new coating framework and a kit of fans, based on dual ball-bearings. The fans are equipped with IFC-II intelligent system that halts their rotation on low GPU temperature, ensuring noiseless operation.


Sapphire Nitro R7 370 4G D5 is the most cost-efficient solution within the series. It relies on AMD Radeon R7 370 GPU, running at 985 MHz …
