HD 7970 Overclocked to 1.26 GHz: 28 nm Tech Really Stretches Its Legs

Welcome to the first TechPowerUp news post of 2012! Read on for a couple of impressive overclocking feats with the HD 7970 graphics card.

It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest - excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.

VR-Zone have spent the New Year weekend overclocking this beast, having reached a whopping 1.26 GHz core clock speed with their HD 7970 - and decent benchmark improvements to go with it. Also, with the fan at 100%, the card never got above a very comfortable 68 degrees centigrade while running Furmark, which is amazing considering how this test is specifically designed to heat a graphics card to the max - but please see the update at the bottom of the article. The stock cooler may be noisy, but it's certainly very effective: an excellent result which will prolong the working life of the card.

Ivy Bridge Early Sneak Performance Peek: Any Faster Than Sandy Bridge?

Intel's Ivy Bridge line of processors are not due for release until spring 2012, but it looks like Chinese website Coolaler has scored a sneak peak at the performance level of Intel's 22 nm Ivy Bridge platform by testing an engineering sample of a quad core CPU. The screenshot shows CPU-Z & Task Manager (no HyperThreading) readouts, while the AIDA64 Cache & Memory benchmark has been run. The CPU used is a 2 GHz sample as shown by the photo, which CPU-Z reports as running at its 2.4 GHz turbo boost speed (20% overclock) on a Gigabyte GA-Z68X-UD7-B3 motherboard. Rough and ready verdict: about the same speed as the current Sandy Bridge, but with a significantly enhanced northbridge and graphics core. The AIDA64 scores are actually slightly lower than the current SB scores, but this is likely because the CPU is running unsupported and unoptimized due to a mobo BIOS that's not made for it and a benchmark that cannot measure its true performance. Note the memory speeds, which were run fast at 2134 MHz 6-9-6-24 CR2, further indicating lack of optimization, since these timings suggest somewhat better performance than what was measured.
