They Did It! Official Release of AMD Radeon HD 7990 ‘Malta’

Much rumored reference graphics adapter from AMD has been recently officially introduced. As it was suggested before, Radeon HD 7990, codenamed ‘Malta’, employs two Tahiti XT2 GPUs, each of which contains 128 TMUs, 32 rasterization blocks (ROPs), and 2048 current processors (GCN architecture). Smooth work of both graphics cores is synchronized by means of PLX PEX8747 controller that supports 48 lines of PCI Express 3.0. Nominal clock frequencies ascribed to GPUs operation equal to 950 MHz, but Turbo mode enables the increase of frequencies up to 1000 MHz.



Video memory is represented by GDDR5 memory modules, the overall capacity of which equals to 6 GB (3 GB per each graphics core). Memory modules utilize 384-bit bus and run at 6000 MHz frequency with bandwidth of 288 Gb/sec per core. The incorporated PCB accommodates a single CrossFireX socket for the creation of various graphics configurations, including Quad-CrossFireX. Video interface panel boasts the availability of …

Zalman Introduces Highly Efficient FX70 Passive Cooler

Zalman, a renowned South Korean designer of various hardware solutions, has recently introduced its latest CPU passive cooler, entitled FX70. The new-entry features 110x140x158 mm dimensions and comes without any fans. However, if there is a need to cool down CPUs with the TDP level higher than 80 W, the customer is free to enhance the facilities by adding two 120 mm fans. The latter are fixed to the heatsink by means of four brackets.



Zalman FX70 is an optimal choice for the following platforms: Intel LGA 2011/1366/115x/775 and AMD FM2/FM1/AM2/AM2+/AM3/AM3+. This cooler fits in any mid-tower ATX and larger PC chassis. The cooler’s framework consists of a copper base, pierced by six nickel-plated heatpipes, and of fifteen heatsink plates with an offbeat design, codenamed Twist; they are called to dramatically improve the process of heat management.


Fanless framework is regarded to be an advantage due to three reasons. First of all, pure heatsink provides absolutely no …

Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).



Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).


To continue, GeForce GTX 770 …
