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 …

Announcement of video card Gigabyte Radeon HD 7970 Super Overclock

The efforts of Gigabyte engineers culminated in the release of the Radeon HD 7970 Super Overclock, also known as GV-R797SO-3GD. This is a monstrous construction with height of 64 mm (3.5 expansion slots) and a cooling system WindForce 5X. As well as preparing to be released GeForce GTX 680 SOC, the new adapter uses a five high-speed (> 4000 rev / min) fan size of 40 mm, copper evaporation chamber, and five copper heat pipes.

WindForce 5X – is one of the most expensive VGA-coolers, except for models with water blocks and liquid cooling system. It will allow to overclock Gigabyte GV-R797SO-3GD up to frequencies of 1155/7620 MHz. However, neither the temperature nor the noise performance of video card can be considered satisfactory: 85 degrees under load and 91 ° C for overclocking with increased voltage, and 8000 rpm in a heavy-duty (1185 MHz, 1.375 V) explains the situation.

Printed circuit board Radeon HD 7970 SOC is reinforced with five polymer capacitors NEC / …

Athlon II X2 221 and 198 Sempron X2 (FM1) appeared in the systems HP

It is well known that part of hybrid processors AMD for platform Socket FM1 have a non-working graphics power, so for their release the market brands Athlon and Sempron are used. Last fall, it was reported about the upcoming appearance in the sale of dual-core chip Athlon II X2 221 and 198 Sempron X2, but information about its actual release appeared only now. This hitch is not surprising, given the fact that these processors are still used only on computers in the collection of HP brand for the Chinese market.

Sempron X2 198 (2.5GHz) was seen in the budget desktop HP Pavilion p6-1152cx, p6-1159cx, p6-1230cx and p6-1231cx. This CPU includes two core architectures AMD K10.5, 2x512 KB cache of second level and dual-channel DDR3-1600. The TDP level is 65W.

Athlon II X2 221 clock frequency is 2.8 GHz. Other characteristics of processor are the same as in the lower Sempron X2 198. Both models support 64-bit code, virtualization, AMD-V and instructions even SSE4a. Athlon II X2 …
