Thanks to the new price reductions, the vanilla RADEON HD 7970 from AMD still remains attractive, can deliver quite good performances even at high resolutions as 2560x1440 and when overclocked it becomes a serious competitor even for the Nvidias' flagship, the GTX 680.
Next month AMD will introduce their latest family of graphics chips, called "Southern Islands," based on a completely new architecture and supporting the new PCI Express 3.0 protocol. The first model to be released will be the most high-end model, the Radeon HD 7970, codename "Tahiti," which will cost USD 550. Let's check its performance.
Armed with only our fists, we slayed the murderous fire breathing dragon and rescued the princess (actually the last HD 7970 to complete our 4-way quadfire feature). This time, we have also included 5760x1080 Eyefinity tests in Battlefield 3 and DiRT3, complete with videos!
Today we take a detailed look at the Radeon HD 7970 in the latest games, including Star Wars: The Old Republic and Batman: Arkham City. Added to that is GPU computing performance as well as 1080p playback tests and power, thermal and noise testing.
A few days ago we introduced you to the concept of of frametime tests, a more accurate way of gauging graphics card performance in video games. Today we are applying the new test for the first time, and with the new data we will compare the AMD Radeon HD 7970 GHz Edition to the Nvidia GeForce GTX 680.
Over six months ago AMD released the AMD Radeon HD 7900 series with the introduction of the Radeon HD 7970 'Tahiti' graphics card. This card became the flagship video card for AMD and has proven itself to winner. AMD recently announced the Radeon HD 7970 GHz edition, which is a newer version of the Radeon HD 7970. Read on to see what the changes are and if this card is right for you.
When it was released last December, the Radeon HD 7970 was the fastest single-GPU video card available on the market. However, the GeForce GTX 680, released in April, proved to be faster. To counter the faster GPU from NVIDIA, AMD first dropped the price of the Radeon HD 7970, and now is releasing a second version of the Radeon HD 7970, dubbed "GHz Edition," with higher clock rates. Was the increase of the clock rates enough to take the crown away from the GeForce GTX 680? Let's check it out.
AMD have had great success with their latest 7 series of discrete graphics cards. The HD7970 led the performance charts for some time until Nvidia released their flagship single GPU, the GTX680. AMD are attempting to answer the challenge with the HD7970 ‘GHZ’ Edition, earning the moniker from the enhanced default 1ghz+ core clock speed.
What do you do when you have a succesful high-end video card and your main competitor suddenly introduces an ever faster card? You go back to the drawingboard and think of a way to squeeze more performance out of your existing products. That's exactly what AMD did with the Radeon HD 7970, the end result of which is introduced today in the form of the Radeon HD 7970 GHz Edition. It's all in the name, this is a Radeon HD 7970 with a 1GHz GPU with turbo mode.
With a refined manufacturing process and a tweaked firmware/bios AMD are today launching a revised 7970 known as the GHz Edition, or XT2. We will be comparing that card to an overclocked, custom design GTX 680 and will dispense with the niceties, clocking our i7-3960X CPU at 5.0GHz and firing the resolution up as high as 5760x1080.
