NVIDIA GeForce GTX 680 Bewertung | 118 Daten im Vergleich

The Overclockers Club review of the NVIDIA GTX 680 highlights the Kepler-based GPU as a fast and power-efficient single-GPU solution, boasting 1536 CUDA cores and a 195W TDP. Key advantages include impressive performance-per-watt, quiet operation, and the efficiency of GPU Boost technology, which allowed for significant overclocking to 1305MHz on the core. Conversely, the review identifies the 2GB GDDR5 frame buffer and narrower 256-bit memory bus as potential limitations compared to competitors. Additionally, memory overclocking headroom was limited, and some features like NVENC were not fully utilized at launch.

The TechPowerUp review highlights the NVIDIA GeForce GTX 680 as a landmark 28 nm Kepler release, offering superior performance-per-watt and beating the Radeon HD 7970 in gaming benchmarks. Key advantages include smart dynamic clocking, quiet cooling, and supports for up to four monitors. Conversely, the card lacks deep low-power states, resulting in higher idle power usage, and features limited, non-software-controllable voltage regulation on the reference design. Additionally, the 2 GB memory capacity was noted as potentially restrictive for a flagship, and the cooler emits a noticeable odor under heavy load.

The Legit Reviews NVIDIA GeForce GTX 680 Video Card Review marks the highly anticipated debut of the 28nm 'Kepler' core architecture (GK104), officially dethroning the aging Fermi-based GTX 580. Priced at a competitive suggested retail price of $499, the card delivers massive structural upgrades, tripling the CUDA core count to 1,536 and doubling the texture units compared to its predecessor. Operating at a base clock speed of 1,006MHz (with a 1,058MHz Boost clock) and featuring 2GB of GDDR5 memory across a 256-bit bus, the GTX 680 achieved a massive compute performance leap from 1,581 GFLOPS to 3,090 GFLOPS. Real-world benchmarks across major DirectX 11 titles like Battlefield 3 and Just Cause 2 cemented it as the fastest overall gaming graphics card at launch, outperforming more expensive competitor options. The primary pros highlighted in the review focus heavily on its class-leading performance-per-watt efficiency. Despite its staggering performance gains, the GTX 680 lowers its TDP to just 195W (requiring only two 6-pin PCIe power connectors), resulting in a monumental 119-watt decrease in peak power consumption compared to the GTX 580. Furthermore, its...

The AnandTech review concludes that the NVIDIA GeForce GTX 680Go to product viewer dialog for this item. successfully retook the single-GPU performance crown at launch, utilizing the 28nm Kepler GK104 architecture to deliver significant improvements in efficiency. Key pros highlighted include superior power efficiency, a quieter stock cooler, and advanced features such as GPU Boost and Adaptive V-Sync, which helped it outperform competition in major titles. However, the analysis on page 7 reveals that the 256-bit memory bus acts as a significant bottleneck in bandwidth-heavy scenarios, representing the card's main con. Specifically in Crysis: Warhead, the GTX 680 fails to outperform mid-tier competition, requiring manual memory overclocking to achieve marginal, 8% performance improvements. www4.anandtech.com
