Leadtek Quadro FX 1800 Review (Part 2)

Quadro FX 1800 - a professional workstation video card

Slightly over a week ago we showed you Part 1 of the Leadtek Quadro FX 1800 video card review here, now we'll continue with Part 2. If you haven't read Part 1, we suggest you do, and if you have no idea what Quadro is (compared the the more popular GeForce), then we suggest you read the primer which is mentioned in Part 1, and where to look for it. Now let's continue!

Energy

It's a small world after all...

Energy is a big issue in today's world. From global warming to climate change and fossil fuels and green alternatives, energy efficiency is a important element for our current state of survival if we're to go further without screwing up the planet even more - conspiracy theories aside about how the greenhouse effect is just a phase of the Earth. So it comes no surprise that today's electronic devices focus heavily on their power consumption and the Quadro is no different.

Unlike the GeForce, which is designed for 3D games and thus won't be taxed at it's full potential for hours (unless perhaps inside a cyber-cafe!), the Quadro might be used for hours on an end, especially since it's designed for work while the GeForce is for play. Think about it - what do you spend more time on? Working or playing? Well if you're a professional gamer it's out of the question!

Look! No power ports!

So it becomes obvious that the Quadro needs to factor in electricity savings as well and boy does it! At first glance you'll notice the Leadtek Quadro FX 1800 does not have any PCI Express pin power requirement at all! On the other hand, the GeForce GTX 285 needs a whopping dual 6-pin PCIe power plugs from your PSU (Power Supply Unit)! Keep in mind only high-end PSUs above 600-Watts or so MAY have dual PCIe power connectors so you may also have to buy a new PSU if you're using the GeForce 285!

You'll need DUAL 6-pin PCI Express power plugs from your PSU!

So how much power DOES the 285 consume as compared to the energy-efficient Leadtek Quadro FX 1800? To measure this, we'll need to use what's called a Plug-In Power Monitor, which basically shows how much electricity (measured in Watts) is being drawn from the electrical socket to be used by the computer which is having the respective card installed in it.

37Watts more while running - and that's only idle! So you can imagine what happens during intense full usage like being taxed by 3D processing! Now multiply that by the minutes, hours, days, weeks and months you'll be using a 285 as compared to this Leadtek Quadro FX 1800 and you'll soon be running up a huge bill that you could save were you running the Quadro instead!

Here's the YouTube videos from BrickGamers Channel where you can see the power difference when the Leadtek FX 1800 and 285 powers up. Both are running on the same platform, so the differences you see in Watts being consumed shows directly how much is used:

Thermals

The side-effect of energy is heat and once again this can be seen in the Leadtek Quadro FX 1800 as compared to the 285. Notice how much cooler the 1800 runs compared to the 285:

Extra power consumption aside, all these extra heat also spells cooling, which means you need to spend more power to not only cool the card, but also the insides of your computer casing, to prevent other components from heating up and overall slowing down your whole machine. So what you have here is both extra power consumption in terms of running the 285 as well as cooling it. This is yet another aspect where the Quadro shines in and is worth that extra cost.

Part 3 we'll look at the gaming aspects of the Quadro FX 1800. While it's not a gaming card, it's good to see just how much it can do so you do get to also play some games on it after working!

Intel Core i5

As mentioned previously, Intel will be coming out with their new processor (CPU), the Core i5. It is now out, designed to work on desktop boards powered by the equally-new Intel P55 chipset (board controller). These new boards will also work with the new Core i7. But wait, this new Core i7 is not the same as the older Core i7! Confused? Read on.

This new Core i7 differs from the previous Core i7 in a two ways:

• Old i7 is a LGA1366 socket CPU, supports triple-channel DDR3 memory, on desktop boards powered by Intel X58 chipset
• New i7 is a LGA1156 socket CPU, supports dual-channel DDR3 memory, on desktop boards powered by Intel P55 chipset
  

As you can see, the new i7 is the same as the i5, whereas the old i7 works by itself. As also mentioned previously, Intel did this so owners of existing dual-channel DDR3 memory (RAM) on desktop boards powered by the Intel 4-Series chipset (like the P45) wouldn't have to waste their RAM.

The new Intel Core i5 processor. The new Core i7 processor looks just the same too!

Plus, now that you have two CPU types to select from, you have even more choices depending on your needs. But what's the difference between the new i7 and the new i5 then? Hyper-Threading. The new i7 has HT, while the new i5 doesn't have HT. The old i7 has HT too, by the way. As you can see, this makes the CPUs available from high-end (old i7), middle-range (new i7), and mainstream (new i5). But what is HT?

The new Intel Core i5 processor in its new LGA 1156 socket on a new Intel P55 board

HT is basically a feature where a single CPU core can function as a quasi dual-core, albeit not as fully-functional as a full-fledged dual-core. So the old i7 and new i7, both being quad-cores with HT, you effectively have quasi octo-cores, while the new i5, being quad-core without HT, is just a quad-core. Again, just to remember, the difference between the old i7 and new i7 is the number of RAM module sticks it supports.

So there you have it. Decide on how much power you need, and then you can go get the right type of CPU to meet your needs. The new i5 with 4 cores and dual RAM, the new i7 with 8 'cores' and dual RAM, or the old i7 with 8 'cores' and triple RAM. New i5 and new i7 need P55 boards, old i7 needs X58 boards.

Crash, Boom, Bang?

If you haven't heard by now, Microsoft has re-named its Web search engine from Live Search to Bing, in an attempt to make it more "user-friendly". However, this "new" search engine got into a little trouble recently when it was found to be selective of the type of results to show depending on the search being queried. Want to know more?

In particular, it was sensitive towards searches that would highlight the "bad" side of Microsoft. This came to be known via here, and a screen capture here proved the point, especially since it has now been changed to reflect no "censorship", as seen from here. Just to be fair, Google was put to the test as well, as seen here. Well, it's good to see Microsoft redeem itself than to deny!

Leadtek Quadro FX 1800 Review (Part 1)

Few weeks ago we mentioned here that we'll be coming out with a review on the Leadtek Quadro FX 1800 video card, designed for professional usage on workstation computers. Now we follow up with the Quadro's performance. If you need a primer about this, we suggest you read our initial post to get a better basic understanding before we proceed further in the tests.

As mentioned before, a Quadro is different from a GeForce, which is designed for gaming in mind, but this isn't so apparent when the price of a Quadro is higher than a GeForce. For comparison sake, let's take the most powerful single-GPU GeForce out there, the 285. Based on Google Product Search, we can see the GeForce 285 costs around USD300, while the Quadro FX 1800 costs about USD400. So what do you get extra or better for the higher costs it asks?

Bandwidth

Let's start with something simple - the bandwidth. The slot that the Quadro sits in, PCI Express 2.0 interface, supports up to 5GBps (the older PCI Express 1.0 slot only supported up to 2.5GBps).

Quadro makes full use of this PCIe 2.0 slot by hitting the 5GBps limit (red arrow above), while the GeForce 285 only uses up to 4.6GBps (red arrow below) of the slot's 5GBps limit.

You might ask - "Wait! What's that 12GBps in the 285 under Device to Device Bandwidth, where the Quadro only got 2GBps?" Good question! That's the internal bandwidth on the card itself, not between the card and the mainboard.

A GeForce needs this speed because in games, it's all about fast scenes so the GeForce has to process things quickly inside the card. In Quadro however, the card needs to quickly update the display during complex 3D work, so it needs to get back to the user faster - hence the faster bandwidth between the card and the computer.

That doesn't make any sense? Think of it this way - when you're playing a game, you're moving about in a 3D world, the card has to visualise this world as you move so it needs to quickly do "behind the scenes work", basically processing the scene ON the card.

Now when you're doing 3D work, you're manipulating a 3D scene, so the card needs to update the object fast - this means it has to continuously feedback 3D objects to the user manipulating it. Let's move on.

2D Wireframe @ 3D Programs

Performance Test is a tool that comes with Intel X58 Desktop Boards, designed for the Intel Core i7 quad-core desktop processor with integrated triple-channel DDR3 memory controller. Intel bundles the full version 6.1, although PassMark (which makes Performance Test) now has version 7.

PT 6.1 shows that the Quadro performs better for 2D Graphic Lines and Shapes, as well as 2D GUI (Graphical User Interface). This is exactly what Quadro is designed for in 3D work.

That doesn't make sense either? Think of it this way - while you're working with 3D objects, the wireframe of these objects are basically 2D lines making up the 3D object. Now onto it in action.

For this, we'll need a real-world scenario the Quadro card is designed for - a 3D program. While there are many options out there, with AutoDesk's Maya being the leader, it also costs around USD3,500. So let's turn to the most popular Open Source (free) 3D program currently - Blender.

To see Quadro at work, we'll need to load a 3D model into the program. Like 3D programs, most models aren't free either, but since Blender is free, there are some free Blender models out there. To stress the Quadro, we'll use a complex 20MB 3D model by Dennis Bailey and Eric M Clark of the fictional starship Enterprise from the science-fiction franchise Star Trek.

This is how it looks like once you've opened the Blender model file (called Blends) in Blender:

If you render the 3D model, it will look like this:

Now to see Quadro at work, you've got to see how Quadro renders 2D lines in a working environment, in this case, while you're manipulating a model. To show you this, we have to record a video of the model being manipulated, and we took a snapshot of the video during it too:

This is the Quadro FX 1800.

This is the GeForce GTX 285.

Here are the videos of each card using Blender so you can see for yourself what we mean. Feel free to pause these videos at the above screen capture image positions to see it for yourself. It is advisable to toggle the HQ (High Quality) button in these YouTube videos to see it clearer.

GeForce GTX 285

Memory Advantage

As you can see, Quadro does a very fine job (literally) to render accurate and precise 2D lines when you manipulate a 3D object in a 3D program, giving you exactly what you need, something which GeForce cannot deliver with its blurry and jagged 2D lines. This is also due to the faster memory the Quadro has which the GeForce lacks, as seen in these below shots of CPU-Z:

The GeForce GTX 285 has faster Core and Shader, but a slower Memory Clock than the Quadro FX 1800. This is also mirrored in Everest (formerly AIDA), an information tool:

There're also some other details there, like a faster Shader and Geometric Domain GPU Clock in the Quadro FX 1800 (550MHz and 1.4GHz) versus the GeForce GTX 285's 301MHz and 602MHz under Graphics Processor Properties.

Then under Memory Bus Properties, you'll find the Quadro's 800MHz Real Clock triumphing the GeForce's 100MHz while the Quadro's Effective Clock is 1.6GHz versus the GeForce's 200MHz. In summary:

Now do you begin to see what the extra USD100 is worth compared to the the most powerful gaming GPU? Next week we'll continue the review with Quadro's differences in Heat, Energy, and Power usage. Then we'll show you how the Quadro can also handle same games on the side!

640Kbps Should Be Enough For Everyone

The following comic is based on a true story

There is only a handful of people who know about this event which transpired, and we're happy to let you know that BrickTech is one of them :) As to who and what this refers to, we'll leave you to figure that one out ;) Rest assured, we swear upon our LEGO® plastic miniature figurines, it's the whole truth and nothing but the truth. Sometimes fact IS stranger than fiction.

By the way, if you didn't catch the relevance of this post's title, then you're not as old as us :P

Dual-Channel Core i7

The Intel Core i7 quad-core desktop processor will soon also come in a version with integrated dual-channel DDR3 memory controller

Don't do a double-take. You read that right. Intel Core i7 quad-core desktop processor with Dual-Channel integrated memory controller, not Triple-Channel. For those who know the Core i7, you'll know it supports triple memory modules, so to go backwards and support dual memory modules is a shocker! So why is Intel doing this?

Because the Core i5 desktop processors will be coming out, which comes with an integrated dual-channel memory controller, so offering the Core i7 with the same feature allows users to select from the middle-range Core i5 or the high-end Core i7 while keeping their current dual memory modules from the previous Core 2-class of desktop processors. Want to know more?

By the way, this is of course, assuming you were using DDR3 memory and not DDR2, as some previous desktop boards which supported the Core 2-class of desktop processors only supported DDR2 memory. If that's the case then you can also consider going for the triple-channel Core i7 since you'll be upgrading your memory anyway! This new dual-channel Core i7 is designed for users who already are using DDR3 memory, but want more power than the Core i5.

So what happens to the triple-channel Core i7? It will still be there as a top-end quad-core desktop processor, and for those who are willing to buy new triple memory modules, as well as need more memory, specifically if they're using an x64 (64-bit) operating system, which can use beyond 4GB of memory.

How would you know the difference then between a dual- and triple-channel Core i7? The triple-channel still maintains the LGA1366 processor socket while the new dual-channel Core i7 and i5 (as well as entry-level dual-core i3) will use the LGA1156 processor socket instead. That's right, there'll also be a Core i3 dual-core entry-level desktop processor for those who don't even need the power of the Core i5.

The new LGA1156 processors will be supported by desktop boards powered with Intel's P55 board controller (chipset), while the LGA1366 Core i7 processor will continue to be supported by Intel's X58 chipset. That's not the end of the Core i7 triple-channel class processors though. Intel will also release the Core i9, a six-core desktop processor for the Core i7 platform.

Stay tuned for more updates about these new processors if you're confused about them.

Internet Censorship

Those who have observed Malaysia's 12th General Election on 8th March 2008 will have noticed the Opposition won 5 states from the dominant Government via the Internet, which the Govt had little control over while they were controlling the mass media.

This was even mentioned by Vinton Cerf, Father of the Internet @ WCIT 2008 - which you can read more about him here in our previous post (at the bottom of that post). He mentioned about how the Internet has shown it plays an important role in politics, and it has even resulted in the world's first blogger to be voted into Parliament, which is Malaysia's case, is Jeff Ooi. So what has the Gov tried to do? Read on for more.

As a result, in order to work towards securing the 13th GE in 2012 from being lost, the Govt has begun to blog like the Opposition, and has recently decided to attempt to filter the Internet, just as how China tried with their Green Dam project.

However, as Jack of BrickGamers have said, if even the Middle Kingdom can give up (at least for now), perhaps it's futile for the Govt here to consider pursuing this when it actually contradicts the MSC (Multimedia Super Corridor) Bill of Guarantees, which prohibits Internet censorship to encourage foreign investments in the country.

So far the Govt has said the filter is only to censor pornography, but we all know power can be abused in the wrong hands once laws are laid down, and in anycase, it still violates the MSC's Bill.
