Sapphire HD 7970 GHZ Edition 6GB Toxic Edition

SAPPHIRE Technology has just announced its HD 7970 6 GB TOXIC Edition graphics card boasting the highest clock speeds in its class and believed to be the fastest single GPU graphics card in the world.

The SAPPHIRE HD 7970 6 GB TOXIC Edition is based on the latest HD 7970 GHz Edition GPU from AMD, together with a host of industry first and exclusive features to deliver maximum performance. Its unique 6 GB frame buffer is a World first for a consumer graphics card and makes the TOXIC Edition ideally suited to multi-screen gaming as well as providing the extra memory required for demanding professional applications such as content creation, video editing or rendering.

Performance is also World leading. By default, the HD 7970 6 GB TOXIC Edition runs at 1050 MHz and with PowerTune Dynamic Boosts rises to 1100 MHz on the engine with the memory clock at 6000 MHz effective. By pressing the new SAPPHIRE exclusive Lethal Boost Button, the beast is unleashed, boosting the core clock speed to 1100 MHz with PowerTune Dynamic Boost to an industry first of 1200 MHz on the engine while the memory is further overclocked to 6400 MHz effective. The fan profile and PowerTune limit is also changed to performance settings. In addition, users will be able to individually tune the card with SAPPHIRE TriXX, the company's free to download software tool that allows key parameters to be adjusted for maximum performance.

This astonishing performance is achieved partly as a result of a completely new power control system developed by SAPPHIRE - the Lethal Power Suite. The Lethal Power suite consists of many premium design features. These include a new 8 phase power design for the GPU VDDC, with an additional one phase each for VDDCI and MVDD. The design uses a brand new double sided Black Diamond Choke for the first time, as well as DirectFET technology and all on a 12 layer PCB to ensure the board runs fast and stable. (The double sided Black Diamond Choke design reduces the temperature around the power design portion by 40 degree Celsius in lab test when compared to the reference PCB design.)

Cooling a card with such extreme performance demands a special solution - and the SAPPHIRE HD 7970 6 GB TOXIC Edition has it - with a new implementation of SAPPHIRE's World acclaimed Vapor-X technology. The Vapor-X cooler on the TOXIC Edition is based on a new vapor chamber designed especially for this model. Heat is carried away by four heatpipes (2 x 8 mm plus 2 x 6 mm), and finally dispersed by two 90 mm fan with aerofoil blades and dust repelling bearings.

The Vapor-X cooler easily handles the heat generated from Toxic HD 7970 even when it is running at over 1200 MHz. Additional peace of mind for the user is provided by another new feature - the PCB Temperature LED: The SAPPHIRE HD 7970 6 GB TOXIC Edition has a built in onboard LED for users to monitors the PCB temperature.

Based on AMD's Graphics Core Next architecture, the SAPPHIRE HD 7970 6 GB TOXIC Edition supports all the latest demands of multi-screen applications, multi-threaded Application Acceleration with stream processing, fast HDMI support for high resolution and stereoscopic 3D displays and all the Direct Compute features incorporated in the latest operating systems. But with its exciting feature set the SAPPHIRE HD 7970 6 GB TOXIC Edition is able to deliver all this with the highest levels of performance ever achieved from a single GPU.

The SAPPHIRE HD 7970 6 GB TOXIC Edition is a limited edition product that will be available to order from SAPPHIRE etailers and retailers from 17th July 2012.

AMD HD 7800 series

 The HD 7800 series also brings the much vaunted Graphics Card Next architecture to replace the aging VLIW4/VLIW5 designs of previous generations. Feature wise, the HD 7800 series has the same selling points that we've seen from new AMD cards over the last two months, including improvements in process/power efficiency, flexible multi-monitor configurations. We are told that we will not see actual retail cards until 19th March (2 weeks from this post). The consolation is that there will be an impressive array of custom AIB board designs/bloat when it does hit the shops.

A shorter version of the 7850

AMD 7870

 The 7870 GPU core is clocked at 1000MHz, 11% higher than the HD 6870, and the GDDR5 memory operates at 1200MHz (4.8GHz DDR), which is 14% higher than the HD 6870. The HD 7870 is paired with a 256-bit wide memory bus providing a theoretical bandwidth of 153.6GB/s or 14% more memory bandwidth than the HD 6870. While the HD 6870 typically came loaded with a 1GB frame buffer, the 7870 has been upgraded to 2GB. We've found that when using multi-monitor setups at extreme resolutions, the larger buffer of AMD's cards provide a significant advantage over Nvidia's, which are limited to 1536MB for the most part. he HD 7870's core configuration also differs from the 6870’s. The new card carries 1280 SPUs, 80 TAUs and 32 ROPs, up 14% from 1120 SPUs and 43% more TAUs from just 56. Like the Radeon HD 7970 flagship, the HD 7870 adopts the 28nm design process and is also PCI Express 3.0-compatible. The new interface spec doubles its predecessor's bandwidth to 32GB/s. Unfortunately, no current processor or chipset supports this technology, so we'll have to test it down the road. To feed the card enough power, AMD has included a pair of 6-pin PCI Express connectors -- the same setup you'll find on the HD 6950 and GTX 570 and other demanding boards.

Naturally, the HD 7870 supports Crossfire, though there is just a single connector meaning it is only possible to pair two cards. The only other connectors are on the I/O panel. Our reference sample has a dual DL-DVI connector, a single HDMI 1.4a port and two mini-DisplayPort 1.2 sockets.

All HD 7870s can support a max resolution of 2560x1600 on up to three monitors. With a multi-stream hub using the mini-DisplayPort 1.2 sockets, the card can power up to six screens.

AMD 7850

The core clock frequency has been lowered from 1GHz to 860MHz which has reduced the compute performance from 2.56 TFLOPS to 1.75 TFLOPS, a 32% reduction. At 860MHz the new Radeon HD 7850 is clocked 4% slower than the HD 6870 and 11% higher than the HD 6850.The GDDR5 memory still works at 1.2GHz, which is effectively 4.8GHz DDR. Because the memory bus is still 256-bit wide the bandwidth remains at an impressive 153.6GB/s, which is 20% greater than the old HD 6850.AMD has also kept the card's capacity at 2GB which is the same amount of memory that can be found on the older Radeon HD 6970 and HD 6950 graphics cards. Where the Radeon HD 7850 really differs from its bigger brother is in the core configuration. The HD 7850 has been downgraded to include 1024 SPUs and 64 TAUs (down from 1280/80), while the ROPs remain at 32.At least on this reference board, the Radeon HD 7850 uses the exact same cooler as the HD 7870. Note however that the Radeon HD 7850 lowers its load consumption to 130 watts, 26% less than the HD 7870. The Radeon HD 7850 is a PCI Express 3.0-compatible graphics card just like the HD 7870. The HD 7850 doesn't require but a single 6-pin PCIe power connector. This means Crossfire setups only need a pair of 6-pin PCIe connectors from the PSU, which is a very mild requirement.Finally the same I/O panel configuration has been used: a dual DL-DVI connector, a single HDMI 1.4a port and two mini-DisplayPort 1.2 sockets. All HD 7850 graphics cards support a max resolution of 2560x1600 on up to three monitors. With a multi-stream hub using the mini-DisplayPort 1.2 sockets, the card can power up to six screens.
