SPECapc Lightwave

SPECapc (Application Performance Characterization) tests are fundamentally different from the SPECviewperf tests. While SPECviewperf tests incorporate code from the various test programs directly into the benchmark, the SPECapc tests are separate scripts and datasets that are run against a stand-alone installation of the program being benchmarked. SPECapc group members sponsor applications and work with end-users, user groups, publications and ISVs to select and refine workloads, which consist of data sets and benchmark script files. Workloads are determined by end-users and ISVs, not SPECapc group members. These workloads will evolve over time in conjunction with end-users' needs and the increasing functionality of PCs and workstations.

For this test, I ran the SPECapc "Lightwave" benchmark against a trial installation of Newtek's Lightwave 3D product. The benchmark, developed in cooperation with NewTek, provides realistic workloads that simulate a typical LightWave 3D workflow. It contains 11 datasets ranging from 64,000 to 1.75 million polygons and representing such applications as 3D character animation, architectural review, and industrial design. Scores for individual workloads are composited under three categories: interactive, render and multitask.

The benchmark puts special emphasis on processes that benefit from multi-threaded computing, such as animation, OpenGL playback, deformations, and high-end rendering that includes ray tracing, radiosity, complex textures and volumetric lighting. The test reports three scores: Animation (multitasking), Animation (interactive), and Rendering. The numeric scores represent the time it took to complete each section of the benchmark, in seconds, so lower scores are better.

I've found the SPECapc Lightwave 3D test to be an excellent indicator of overclock stability. In many cases, overclocked systems that will make it through every other benchmark here will crash in this test.

Here we see another application that Virtu can't handle, and another non-gaming application that benefits greatly from a discrete graphics card....at least for animation, where the Radeon 6850 configuration runs in less than half the time of the iGPU configuration. Overclocking the COre i7 2600k helps tremendously in the animation tests, more than doubling the overall performance.

The raw rendering test apparently uses only the processor, and here we see another example of the Z68 chipset-based motherboard beating the P67 system. Overclocking the Z68 system, though, only nets a performance gain of 12%, significantly smaller than we've seen in the other tests.

Will the time ever come, when you will be able to flick that switch on the front of your case that switches off your HD6990/GTX590 card,reverting back to using your integrated cpu graphics, for when you just want to surf the net?

Therefore saving you not only wear & tear on your fancy new amd/nvidia card but also electric, which lets face it, ain't cheap nowadays...

I reckon my idea could be the saviour of the desktop PC :o)

Why flip a switch? Let the computer do it for you. Granted, Virtual will not run in I-Mode with either of the dual-GPU cards you mentioned, but Synergy hopefully will with the 590.

Not much bad to say about these new boards. Intel has the cash to develop just about any idea they can imagine to see if it works. With gigantic resources to dip into, they are a force to be reckoned with.

# I miss the PS/2 connector(s)Olle P 2011-05-11 06:47
PS/2 is really the way to go to avoid lag/latency in the response when things heat up. (Plus I do use it!)

# RE: I miss the PS/2 connector(s)David Ramsey 2011-05-11 16:33
Technically, yes, but unless you type more than, say, 100 keys per second, you're never gonna notice the lower latency of PS/2. Its only real advantage is that it support n-key rollover, whereas I think USB tops out at 6 keys...still enough for humans. Cyborgs, aliens, and keyboard testing machines might want more...

# How much ram can it takeLong Rod Von Hugen Dong 2011-05-11 16:23
How many ram ports or whatever they are called does this have? Im hoping I can get 24 gigs in this (I think I need six ports). Yea mah friend found 24 gigs for 280 bucks :o seems like a decent deal.

# RE: How much ram can it takeDavid Ramsey 2011-05-11 16:30
There are four slots for RAM, as several of the pictures, including the one on the first page of the review, clearly show. With 4G DIMMs you could put a maximum of 16G in this motherboard. So you'll need an X58-based system to go any higher than that.

For what app or purpose. There is no app I know of that requires 24Gb let alone 12Gb of RAM. Transcoding? Video procesisng? Then you need a professional GPU.

I make some use of 12G of RAM on my Hackintosh, mainly because I run Windows 7 in a virtual machine pretty often while the Mac's doing stuff in the background. Actually, I don't think I've ever measured RAM use above 8G, but I think it could happen!

Personally, I like Corsair memory because of their hassle-free lifetime warranty...

# Is virtu really any good?Aditya 2011-05-12 07:09
I'm confused on how virtu will switch on the integrated graphics, I mean do you connect the board as well as the gpu connectors to the same monitor or do the on-board connectors let you switch between either solutions.

All your questions are answered in our separate article "Lucid Virtu Graphics Virtualization Technology". The quick answer is "There's only one connection, either to the motherboard or the graphics card depending on the Virtu mode you select."

What is the release date of the board-- when it becomes available in the market.

# compatibility of heatsinkdoc 2011-06-26 17:58
A quick question about the heatsink for the Z68 test system. What fan configuration did you use for the heatsink (i.e, Dual-pull or dual-push).

Also was there any clearance issues with the heatsink and the ram? Would you say that the ram had fairly tall heatsinks or not?
Would you say the ram you used is similar in dimensions to the G.skill RipjawsX?
Thanks

# RE: compatibility of heatsinkDavid Ramsey 2011-06-26 19:32
The fans for the Silver Arrow were set up as pull-push, actually. Putting the fan in front of the first set of fins would have blocked the first two RAM sockets. As it was, the first RAM socket was blocked by the heat sink.

On P67/Z68 motherboards I've used, the CPU socket is fairly close to the RAM sockets, and low profile memory would be a good idea. The G.SKILL memory I used wasn't low profile!

# RE: ASUS P8Z68V PRO Motherboarddoc 2011-06-26 22:56
Hmm, ok. Thanks for the reply.

So if you had the fans in pull-push, does that mean both fans were in the middle cavity of the Silver Arrow? (sorry just a bit confused on how you configured that)

I checked out the P8Z68V-PRO manual and it recommends installing RAM in the second/fourth slots, so I guess it wouldn't matter too much if the heatsink blocked the first RAM slot. (unless I planned to fill them all up).

Been thinking of getting G.SKILL RipjawsX, which I've checked are about 40mm tall, and the height of the Silver Arrow's base to the first fin is 40.87; it should just slip in.
Of course I'll probably have to position the fans left||centre instead of centre||right; or use a 120mm fan.

But thanks for the help.

I have not reviewed the ASRock board, but you really couldn't go wrong with the ASUS.

if you see here ##tomshardware.co.uk/asrock-z68-extreme4-asus-p8z68-v-pro-gigabyte-z68x-ud3h-b3,review-32188-2.html seems that asrock is better for more reason and asus have just 1% more performance that asus.. some one confirm this?

# CPU Fan CompatibilityDavid 2011-12-03 20:23
I bought the Zalman CNPS 9900 Max CPU fan, but the Backplate that connects to the motherboard does not fit this motherboard. Does anyone know of a good CPU cooling fan that fits the ASUS P8 Z68-V Pro OR a different backplate that fits both the fan and this particular motherboard?

Does the cooler's box specify that it supports socket 1156 or 1156? If so, it should fit. I don't have that specific cooler but I've used a couple of others and there was no trouble fitting them.
