Comment Re:doesn't look like much now, but... (Score 3, Insightful) 160

I recall the same experience... Prior to seeing Wolfenstein3D, I had graduated from Intellivision to the Nintendo NES, and that constituted my main gaming exposure, other than some early versions of Flight Simulator. Wolfenstein3D blew me away with the graphics possible on a computer, and I probably jumped out of my seat a number of times as the immersion was like nothing I'd seen before. A lot of games with impressive graphics since then, but nothing like that first impression... Kind of a cool experience, yields a different sort of appreciation I think compared to that of younger gamers who have a more modern sense of graphics expectations.

Submission + - EVGA Adds GeForce GTX 670 To Nvidia Graphics Lineup

I.M.O.G. writes: "Filling the gap between mid-range graphics cards around the $250 mark and high-end excess that costs upward of $500, EVGA has added a $420 GeForce GTX 670 to NVIDIA's stable of graphics cards. Based on the company's latest GK104 GPU, this GTX 670 offers equivalent performance to the flagship GTX 680 with similar power consumption and a cheaper price tag. The value proposition is strong with this one, although as the Overclockers review points out, the temperatures on this run a touch on the warmer side."

Submission + - Why Is Ivy Bridge Hot?

I.M.O.G. writes: "PC enthusiasts with Ivy Bridge engineering samples, and reviewers at large have come to the consensus that Ivy Bridge is a slightly warmer chip than it should be. An investigation from Overclockers.com found common thermal paste between the CPU die and the Integrated Heat Spreader by removing the IHS of an Ivy Bridge Core processor. Typically on modern Intel processors the IHS is soldered to the die enabling more effective heat transfer."

For people familiar with Intel's Tick-Tock cadence - this should not come as much surprise. Some people may have gotten caught up in marketing and expected more, but this is a "Tick" which brings a process shrink, power savings, and a modest performance increase. It is just about delivering that, though perhaps on the softer side of things.

Sandy Bridge was a Tock - a BIG performance improvement. Haswell should be a Tock - a BIG performance improvement.

On the tick, they set more modest performance goals, and focus on getting the process shrink right and tuning things up. On the tock, they should knock our socks off. So maybe Ivy Bridge is disappointing, but perhaps familiarity with their product development strategy helps to manage expectations

Submission + - Intel Launches Ivy Bridge Desktop CPUs

I.M.O.G. writes: "Intel continues its tick-tock cadence today, releasing their Ivy Bridge architecture bringing their process to 22nm and introducing their tri-gate transistor design. In a process shrink of this nature, clock for clock performance increases are typically moderate over previous architectures. In most all benchmarks, Ivy Bridge is scoring between 3-5% better than Sandy Bridge when compared at the same clock speeds."

I.M.O.G. writes: "Full instructions for how people can attempt CPU Frequency World Records on Bulldozer. I haven't seen anyone with a top 20 world record score share exactly how they did it, so I wanted to be the first to explain how it is done."

Submission + - AMD FX CPU Reviews (overclockers.com)

I.M.O.G. writes: "Today AMD lifted embargo on their most recent desktop AMD FX architecture, code named Bulldozer, whose CPU frequency record Slashdot recently covered. The fruition of 6 years of AMD R&D, this new chip architecture is the most significant news out of AMD since the Phenom II made its debut. The chips are available now in all major retail outlets and top tier hardware sites have published the first Bulldozer reviews already. Without spoiling the news, expect a mixed bag of opinions."

1.9V lifespan would be measured in minutes or hours, not days or weeks. At room temperature, 1.9V would damage the processor almost immediately, if not kill it.

In fancy demonstrations and testing like this, the main magic comes not from voltage, but from super conductivity within the processor at the cold temperatures. The cold also increases the lifespan of the chip when using exorbitant amounts of voltage. This doesn't matter to most people or maybe even the poster I'm replying to, but I'm mentioning it here for the general knowledge of anyone who may be interested in speaking accurately about this.

Ultimately though, its the cold that raises the frequency ceiling - sure the voltage helps, but with super-cooled temperatures alone the frequency ceiling is raised even at default voltage./p.

In regards to frequency scaling for Moore's Law, that came to an end in 2004 essentially. It's one topic wikipedia has right if you want to read the details. These days, moore's law only holds true for transistor density, which is why everything is multicore, power efficiency, and integrating more features on chip - there are extra transistors they can fit on the chip and they are finding more things to use that die area for.
