amazon Sapphire HD 7950 OC 950MHz Edition reviews

The Sapphire HD 7950 OC 950MHz Edition is overclocked with GPU clocking that is clocked higher than the standard clock speed of the Radeon HD 7970 (AMD’s most advanced single GPU). This graphics card supports PCI Express 3.0 and comes with the Sapphire TriXX Utility for quick and easy overclocking.

Design

The Sapphire HD 7950 OC 950MHz Edition is equipped with an AMD Radeon HD 7950 graphics processor (code Tahiti Pro) with the new GCN (Graphics Core Next) graphics architecture and 22nm manufacturing technology. Compared with the old VLIW4 graphics architecture applied on the Radeon HD 6900 series GPU, the GCN architecture enhances the multi-threading capabilities of the GPU, which can better harness the power of processing multiple graphics pipelines at once without significant influence on performance.

Of the graphics card manufacturers overclocked so the Sapphire HD 7950 OC 950MHz Edition GPU operating at the default clock frequency up to 950MHz; Up to 18.75% higher than the standard clock speed of the Radeon HD 7950 GPU (800MHz) and even with the Radeon HD 7970 (925MHz) GPU. In addition, Sapphire HD 7950 OC 950MHz Edition is equipped with 3GB GDDR5 with 1,250MHz clock and 384 bit memory interface.

Unlike some graphics cards equipped with the GPU Radeon HD 7950, Sapphire HD 7950 OC 950MHz Edition requires two 12V power supply lines, one 8-pin PCIe and one six-pin PCIe (equivalent to the Radeon HD 7970 GPU). As recommended by the manufacturer, users should choose 550W or more power supply to ensure the power needs to meet the entire system.

Sapphire HD 7950 OC 950MHz Edition is 275x42x115mm and weighs about 780g. The Dual-X cooling system incorporates two 80mm cooling fans to ensure efficient heat dissipation as well as minimizing the noise generated during operation.

In addition, Sapphire HD 7950 OC 950MHz Edition also supports 3D display technology based on AMD HD3D technology. Support for DVI, DisplayPort 1.2 and HDMI 1.4a, and AMD Eyefinity technology allows up to four monitors to be displayed simultaneously for up to 4096×2160 (4K Support) play game, video resolutions or work with multiple applications at the same time.

Sapphire HD 7950 OC 950MHz Edition supports the next-generation PCI Express 3.0 (PCIe gen3) interface, DirectX 11.1 graphics library, OpenGL 4.2 and OpenCL 1.2. The card also supports CrossfireX technology, ready for game configurations, multiple graphics cards.

In addition to the usual accessories such as the CrossFire Bridge, DVI to VGA converter and two power cables (VGA Molex Power Connector) Sapphire HD 7950 OC 950MHz Edition also comes with Mini-DP to DP converter, HDMI to SL- DVI and HDMI 1.4a cable to output video signals through all monitor interfaces, TV support.

Performance

To test the power of the Sapphire HD 7950 OC 950MHz Edition graphics card, Test Lab uses a test configuration built on the Z77 BMC chipset, Windows 7 Ultimate 64 bit SP1 and the driver included. card. The tests include CineBench R11.5, 3DMark 11, Heaven DX11 Benchmark v3.0 and some DirectX 11 games like DiRT 3, Alien vs. Predator 1.03 and Crysis 2. The tests result in an average of three runs.

Overall test results show that the Sapphire HD 7950 OC 950MHz Edition easily conquered all tests under the Test Lab scenario built with the highest level of graphics. In particular, the power of AMD’s high-end monolithic graphics processor (Radeon HD 7950) has been pushed up to a higher limit by Sapphire, resulting in some tests of Sapphire HD 7950 OC 950MHz Edition also. The Sapphire HD 7970 OC (equipped with Radeon HD 7970 GPU) is no less impressive.

In the DirectX 11 multi-threaded graphics processing experience based on the 3DMark 11 engine, the test configuration reached 7,714 points with performance configuration, resolution 1280×720 and reached 2,587 points with Extreme configuration, resolution 1920×1080; The Sapphire HD 7970 OC graphics card is 4% and 6% lower than the Sapphire HD 7970 OC.

With the Heaven Benchmark, the graphics performance is pretty much similar to 3DMark 11, but it’s mostly about Tessellation technology, one of the most prominent technologies in the DirectX 11 graphics library. The graphics card is far beyond “standard” 30 fps; Both in Ultra mode with the highest graphics setting (tessellation: extreme, shaders: high, 8xAA and 16xAF). Compared to the Sapphire HD 7970 OC lower about 3.7% – 4.1%.

Similar to the DirectX 11 games are DiRT 3, Alien Vs. Predator 1.03 and Crysis 2, Sapphire HD 7950 OC 950MHz Edition still demonstrate the power of high-end graphics cards. Even with Crysis 2, one of the games is classified as a “hardware killer” today, the test results at 1600×1200 resolution and Extreme graphics quality is slightly better than the Sapphire HD 7970 OC.
