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 …

Haswell processors for laptops will consume up to 57 W, desktop - up to 100

Intel provides with three graphics levels: GT1, GT2 and GT3. Desktop processors won’t receive graphics performance higher than GT2, but mobile processors will be able to boast of with GT3 class. Support of PCI Express 3.0 for Haswell processors will be quite usual characteristics, but at the memory controller little progress is seen — yet provides dual-channel DDR3-1600.



By energy consumption Haswell desktop versions will be divided into models with values of 35, 45, 65 and 95 watts of TDP level. For mobile processors the values are ​​37, 47 and 57 W. Finally, ultra book processors with built-in system logic will be filled by TDP level not more than 15 watts. It is assumed that this will enable them, among other things, be in standby mode up to 10 days without charge.


The desire of Intel to compete with AMD in terms of performance integrated in graphics processor, will add some work to companies producing cooling systems for laptops. The developers report about …

Zalman Debuts with Reserator 3 Max Dual Liquid Cooler

Zalman has officially launched a new liquid cooling system, Reserator 3 Max Dual, firstly introduced at CES 2014. It is peculiar by the support of all up-to-date CPU sockets for AMD and Intel platforms, as well as by outstanding performance. With the aim to enhance heat dissipation effect, the company supplements the model with a proprietary Zalman ZM-STG2M thermal grease.



Zalman Reserator 3 Max Dual consists of a waterblock with a copper base, two connecting hoses, two heatsinks, and a pair of 120 mm fans. The base of the waterblock boasts an improved framework; it has got a flanged coating that promotes for the acceleration of heat dissipation. Both heatsink sections are nickel-plated. The heatpipes implemented within their framework resemble a maze; this allows liquid to employ the maximal dispersion area.


The incorporated 120 mm fans are equipped with a long life bearing and a bright blue LED. Their operation is adjusted by means of PWM technology, so the rotational …
