The AMD Radeon HD 7970 review from Overclockers highlights the 28nm Tahiti GPU and Graphics Core Next (GCN) architecture as a major leap, offering roughly 20% better performance than the HD 6970 and surpassing the GTX 580. The card boasts exceptional overclocking, with the core hitting 1125 MHz on stock voltage to match the dual-GPU HD 6990. However, the reference model carries a high launch price and features a loud blower-style cooler. Additionally, limited third-party voltage control at launch and high operating temperatures were noted as potential drawbacks.

The WSGF review of the AMD Radeon HD 7970 highlights the card as a significant milestone, praising the 28nm GCN architecture for delivering exceptional Eyefinity 2.0 multi-monitor performance, which is 43% to 46% faster than the HD 6970. Key advantages include superior widescreen rendering, 3GB of VRAM, and ZeroCore technology that reduces idle power to under 3W. Conversely, the review notes a high $549 MSRP, limited launch availability, and slow developer adoption of PCIe 3.0 and DX11.1 as drawbacks, along with minor in-game loading issues. Despite these, it is lauded as the fastest single-GPU card of its time.

The Guru3D review celebrates the AMD Radeon HD 7970 as a highly impressive flagship launch that firmly establishes AMD's competitive edge for the holiday season. Built on an innovative 28nm architecture codenamed "Tahiti," the card introduces a massive 3GB GDDR5 frame buffer on an upgraded 384-bit memory bus, intentionally optimized to handle high-resolution gaming and multi-monitor Eyefinity setups smoothly. In terms of raw performance, the card easily outperforms NVIDIA's existing lineup, proving to be 20% to 40% faster than the GeForce GTX 580 in modern, demanding titles. Guru3D highlights its massive overclocking headroom—effortlessly hitting 1050 MHz on the core without any voltage modifications—along with exceptionally low idle power consumption (12W) and a highly efficient 6th-generation vapour chamber cooling solution that keeps noise levels firmly in check. However, the launch is not entirely without flaws. Reviewer Hilbert Hagedoorn notes that the initial launch functions primarily as a "paper launch," with actual retail inventory expected to trickle out over the following weeks. While the power management is incredibly efficient under standard loads, multi-monitor setups suffer from a relatively high 45W draw, and...

The TechPowerUp ASUS Radeon HD 7970 CrossFire review highlights extreme 2560x1600 gaming performance from the 28nm "Tahiti" dual-GPU setup, featuring ASUS-specific GPU Tweak software and enhanced aesthetics. Key advantages include AMD’s ZeroCore technology, which drops the idle secondary card to just 1 Watt, though the setup commands a high $1,100 price point. Conversely, the review notes significant cons regarding launch-day driver instability, with missing CrossFire profiles for major titles like Batman: Arkham City and Skyrim, while Battlefield 3 suffered scaling issues at high resolution.
