CineBench R11.5 Benchmarks

Maxon CINEBENCH is a real-world test suite that assesses the computer’s performance capabilities. CINEBENCH is based on Maxon’s award-winning animation software, Cinema 4D, which is used extensively by studios and production houses worldwide for 3D content creation. Maxon software has been used in blockbuster movies such as Spider-Man, Star Wars, The Chronicles of Narnia, and many more. CINEBENCH Release 11.5 includes the ability to more accurately test the industry’s latest hardware, including systems with up to 64 processor threads, and the testing environment better reflects the expectations of today’s production demands. A more streamlined interface makes testing systems and reading results incredibly straightforward.

The CINEBENCH R11.5 test scenario comprises three tests: an OpenGL-based test that models a simple car chase, and single-core and multi-core versions of a CPU-bound computation using all of a system’s processing power to render a photo-realistic 3D scene, “No Keyframes”, the viral animation by AixSponza. This scene makes use of various algorithms to stress all available processor cores, and all rendering is performed by the CPU: the graphics card is not involved except as a display device. The multi-core version of the rendering benchmark uses as many cores as the processor has, including the “virtual cores” in processors that support Hyper-Threading. The resulting “CineMark” is a dimensionless number only useful for comparisons with results generated from the same version of CINEBENCH.

What a nice, linear set of results! CINEBENCH really uses all the threads it can, and the more threads a CPU can dispatch, the better it’s going to do on this test.

In single core rendering, the i7-3820 at 3.6Ghz runs faster than all but the i7-3960X. This is a little strange, considering the i7-3960X runs at 3.3GHz. Perhaps its due to the massive 15MB of L3 cache on the $1k CPU. Multi-core rendering shows no surprises. The i7-3820 is the fasted quad-core on the chart. That’s pretty good, considering its price isn’t much higher than the i7-2600K.

Intel’s Ivy Bridge Lineup Leaked to the Web

March 5th, 2012
Share

There’s been a lot of talk about Intel’s Ivy Bridge platform lately, and specifically whether or not the Santa Clara chip maker’s new CPUs are being delayed until summer. Conflicting reports abound, but one thing we do know is that Ivy Bridge is right around the corner. Thanks to a leaked slide that’s made its way to the Web, we’re also privy to some unannounced details regarding Ivy Bridge.

CPU-World stumbled upon a flipbook PDF file listing a full lineup of desktop and mobile processors from January through April 2012, including third generation Core i5 3xxx and i7 3xxx Ivy Bridge chips.

Missing from the processor list (see partial list above) are Core i3 3xxx Ivy Bridge processors, though word on the Web is that those will be shipping in May or June. The original document (which has since been pulled offline), did, however, detail the existence of Ultra Low Voltage (ULV) Ivy Bridge processors not previously disclosed, including Intel’s upcoming Core i7 3667U (2.5GHz, 25W TDPand Core i5 3427U (1.8GHz, 17W TDP) CPUs.

AMD Launches New Bulldozer CPUs At Substantially Higher Clockspeeds

February 28th, 2012
Share

Ever since Bulldozer’s less-than-spectacular debut, enthusiasts and investors have watched to see if the company would follow up with faster chips that improved overall performance. That’s finally started to happen; AMD announced two new chips today — the quad-core FX-4170 with a 4.2GHz base clock speed / 4.3GHz Turbo mode, and the six-core FX-6200 at 3.8GHz stock / 4.1GHz Turbo.

Both of the new parts are clocked ~15% faster than the FX-4100 and FX-6100 and may offer a slightly faster integrated memory controller as well; rumors indicate that the IMC is clocked at 2.2GHz, up from 2GHz. The new chips are reportedly based on the B3 stepping that’s been in the works for months; current Bulldozer parts are all based on the B2 stepping.

It’s good to see AMD pushing Bulldozer’s clock speeds higher, but there are two indications that the benefits of doing so will be fairly limited. The first is that AMD wasn’t able to hold the 95W TDP mark for either the quad-core or hexa-core variants; both the 4170 and 6200 carry a 125W TDP. The second is that while baseline clocks jumped quite a bit, Turbo Mode core speed didn’t. The 4170’s TM clock is 13% higher (compared to a 16% higher baseline clock) while the 6200’s Turbo Mode is a modest 5% higher than its predecessors.

What this suggests is that AMD has modestly improved power consumption in the CPU’s standard operating voltage, but hasn’t pushed the core’s absolute headroom much higher. This fits with the rumors around AMD’s upcoming 8170; that core is expected to debut a baseline frequency of 3.9GHz (up ~8% from the FX-8150) with a maximum full-load Turbo Mode of 4.2GHz (7% higher).

Pricing on the FX-8120 has also been cut as of these launches, though AMD didn’t provide information on how much. In the wake of Bulldozer’s launch, the FX-8120 and six-core 6100 variants were compared unfavorably with AMD’s older six-core X6 1090T and 1100T. AMD appears to have killed retail shipments of these older parts; neither the 1090T or X6 1100T are widely available, and prices have gone up significantly compared to the 1100T’s $180 price tag six months ago.

The FX-4170 and FX-6200 are showing up online for ~$140 and ~$180, compared to $109 and $149 for the older FX-4100 and FX-6100 parts. The most important achievement of these new parts is that they should at least achieve performance parity with AMD’s older 45nm chips. At 4.2GHz, the FX-4170 is clocked 17% faster than the old Phenom II X4 975 Deneb, while the only hexa-core Phenom II X6 left in stock at NewEgg is the Z6 1045T at 2.7GHz. If the 8170 launches at the expected clock speeds, it should be able to match/exceed the X6 1100T in a similar fashion.

Corsair Hydro Series H100 Liquid CPU Cooler Review

February 21st, 2012
Share

I first ventured into liquid cooling for my computers way back, about a decade ago, for my Intel Pentium 4 “Williamette” and AMD “Duron” based test systems. This was when I was in high school and in my early years of reviewing computer hardware. Back then, the big players in the watercooling market were Danger Den and Swiftech. There were no pumps specific for computer watercooling, so most adopters of liquid cooling used fountain and pond pumps. For radiators, the main choices were the Black Ice series from HWLabs or car heatercores (I preferred Chevelle cores).

Soon after this time period, the liquid cooling market exploded with many new companies in the market and many more component options as a result. While I stayed more in the DIY/enthusiast end of the liquid cooling spectrum, I remember seeing many all-in-one liquid cooling kits appear. I always scoffed at them. They were never really good, with cooling performance not being remotely close to the top-end air coolers they were competing against, and price was always very high.

Today I’ll be looking at a modern version of an all-in-one liquid cooling kit, a class of product I used to dismiss. But it’s been a long time, and as with any other category of computer component, I’d expect this class to evolve for the better over time. Representing our first look at a modern all-in-one liquid cooling kit is Corsair’s H100 Extreme Performance Liquid CPU cooler. The highest end liquid cooler offered by Corsair, the word “extreme” is used by their marketing folks to describe it. We’ll see how that description holds true…

Build and Design

Corsair’s H100 is an all-in-one liquid cooling kit. It comes preassembed and prefilled with coolant (mixture of water and propelyne glycol), and consists of two main parts: the waterblock (with integrated pump) and radiator which are connected with flexible tubing. The H100 was designed to be simple to use with no maintenance required. Since it’s preassembled, installation is made easy as it only requires the mounting of the waterblock and radiator. Those familiar with the assembly of liquid cooling setups know that it’s more complicated than that. The H100 is Corsair’s attempt at bringing liquid cooling to the masses.

The waterblock, with its integrated pump, has an all black colour scheme. Its exterior is mostly all matte black plastic, except for the top which has a glossy insert. The top of the waterblock has a button that controls the speed of the fans that are plugged into it. Three speeds are selectable.

The fan controller integrated into the waterblock supports four fans. The side of the waterblock has four 4-pin PWM fan connectors. The cable coming out of the side of the waterblock ends in a 4-pin molex connector, supplying power for the waterblock and fans.

The other side of the waterblock has the inlet and outlet ports leading to the radiator. The connectors can be rotated as necessary, depending on how and where you install the radiator in relation to the waterblock.

The baseplate of the waterblock is copper. It’s smooth, but with faint-feeling machining marks. Thermal compound comes preapplied to the waterblock.

The radiator in the H100 kit is sized to support two 120mm fans. It’s entirely made of aluminum and is completely painted black. As mentioned earlier, the waterblock contains copper. Normally, in a pure water liquid cooling loop with mixed metals, galvanic corrosion will occur. Typically, aluminum will corrode and and build up on copper surfaces. In the case of the H100 this would be bad as it could lead to leaks in the radiator and clogging of the waterblock. What helps to slow down this corrosion is Corsair’s of propylene glycol additive in the liquid within the H100’s loop. Reassuringly, Corsair backs the H100 with a 5 year warranty, so users shouldn’t have to worry about corrosion for a while.

Intel at ISSCC Detailing Digital Radios and Solar-Powered CPUs

February 20th, 2012
Share

Intel’s presentations at the International Solid State Circuits Conference (ISSCC) this year are focused on one of the biggest problems facing modern CPU designers—how to improve power efficiency without sacrificing compute performance. Intel isn’t just tackling this problem through conventional process shrinks and smaller dies, however; the company detailed multiple new approaches. First up is Claremont, Intel’s first chip built to run on Near Threshold Voltage (NTV) technology.

The term “Near Threshold Voltage” refers to the amount of voltage required to switch a transistor from 0 to 1. Normally, the voltage variation between the two states is significant in order to prevent transistors from activating when they aren’t supposed to. An NTV processor is able to operate much closer to the On/Off point. The result is a significant level of power savings.

Claremont is a bog-standard Intel Pentium that’s been transplanted from its original 0.8µm process (that’s 800nm) to a 32nm architecture. Intel didn’t set out to label Claremont a solar-powered processor; the demo shot below was simply meant to show that the chip could run on extremely small amounts of power. The CPU’s operating parameters indicate such uses are an option; Claremont idles at 280mv at 3MHz and draws just 737mW of power at 915MHz and 1.2v.

For a pertinent example of why this matters, consider the tweaked graph below. The data is from our coverage of Medfield, Intel’s first smartphone processor, but we’ve updated the original with hard figures rather than simply showing a trend line. The reason power consumption increases so sharply as frequency rises, is because higher clock speeds require higher voltages, and raising voltage has a huge impact on power consumption.

It’s not clear yet if NTV would improve power consumption at maximum frequency or if its benefits are mainly confined to lower power modes, but the impact on mobile devices would be substantial. Much of what makes Medfield a huge step forward for Intel is the chip’s ability to minimize its power consumption and rapidly return to standby mode once computational tasks are complete. Smartphones spend the overwhelming majority of time — upwards of 90% — in standby or low-power modes, and that’s where NTV would deliver further improvements.
