AMD Radeon HD 7970 Recensie | 118 Gegevens vergelijking

The TechPowerUp review of the AMD Radeon HD 7970 highlights the debut of the 28 nm "Tahiti" GPU and Graphics CoreNext (GCN) architecture, offering over 30% faster performance than the HD 6970 while consuming less power. Key advantages include 3 GB of GDDR5 memory on a 384-bit bus, PCI-Express 3.0 support, and ZeroCore Power technology for reduced idle consumption. Drawbacks noted in the review include high fan noise from the reference cooler under load, elevated power draw during multi-monitor use, and a steep 549 USD launch price. Additionally, the architecture's 32-ROP count was considered a limiting factor in scaling despite the high-bandwidth memory configuration.

The AMD Radeon HD 7970 introduces the brand-new Tahiti GPU architecture, which utilizes a 384-bit memory interface paired with 1,375 MHz GDDR5 memory to deliver an impressive 264 GB/s of bandwidth—roughly 100 GB/s more than the previous generation. Equipped with 2,048 ALUs running at a 925 MHz core clock, the card manages 3.8 TFLOPS of single-precision processing power. A major engineering advantage is the implementation of AMD's ZeroCore technology, which significantly slashes power draw to just 15 W during typical Windows idle and completely powers down the GPU and cooling fan when the monitor turns off. Furthermore, it debuts support for the high-bandwidth PCI Express 3.0 standard and offers improved multi-monitor setups by restructuring the video output layout, replacing a secondary DVI port with two mini-DisplayPorts and an HDMI port. Despite its robust mathematical performance, the Radeon HD 7970 suffers from notable drawbacks regarding early market viability and thermal acoustic design. The launch functions as a disappointing "paper launch," with physical card supply painfully restricted and unavailable for immediate consumer purchase. On the hardware side, the redesigned cooling fan features...
