Even though Far Cry 2 has its own built-in benchmarking tool with some flythroughs and “action scenes”, we decided to record our own timedemo consisting of about 5 minutes of game time. It involves everything from run-and-gun fights to fire effects. The built-in benchmarking too was then set up to replay the timedemo and record framerates

Metro 2033 (DX11)

Metro 2033 (DX11)


There has been a lot of buzz about Metro 2033 which has mostly centered on its amazing graphics coupled with absolutely brutal framerates on even the best GPUs on the market. For this test we use a walkthrough and combat scene from The Bridge level which starts at the beginning of the level and lasts for about 5 minutes of walking, running and combat. Famerates are measured with FRAPS and Advanced PhysX is turned off.

Unigine: Heaven v2.0 (DX11)

Unigine: Heaven v2.0 (DX11)


Unigine’s Heaven benchmark is currently the de-facto standard when it comes to simple, straightforward DX11 performance estimates. While it is considered a synthetic benchmark by many, it is important to remember that no less than four games based on this engine will be released within the next year or so. In this test we will be using a standard benchmark run with and without tessellation enabled at three resolutions,

8x MSAA Testing (BF: BC2 / DiRT 2)

8x MSAA Testing (BF: BC2 / DiRT 2)


In this section we take a number of games we have tested previously in this review and bring things to the next level by pushing the in-game MSAA up to 8x. All other methodologies remain the same.

BattleField: Bad Company 2 (DX11)
Note that 8x MSAA is enabled via the game’s config file for the NVIDIA cards since it is not a selectable option within the game menu

Core Temperature & Acoustics

Core Temperature & Acoustics


For all temperature testing, the cards were placed on an open test bench with a single 120mm 1200RPM fan placed ~8” away from the heatsink. The ambient temperature was kept at a constant 22°C (+/- 0.5°C). If the ambient temperatures rose above 23°C at any time throughout the test, all benchmarking was stopped. For this test we use the 3DMark Batch Size test at it highest triangle count with 4xAA and 16xAF enabled and looped it for one hour to determine the peak load temperature as measured by GPU-Z.

For Idle tests, we let the system idle at the Vista desktop for 15 minutes and recorded the peak temperature.


HD5870-MATRIX-75.jpg

Even without custom fan speed profiles, the revised heatsink on this card allowed for slightly better temperatures than a stock HD 5870 but without sacrificing the ability to exhaust hot air outside of the case. Would we give up this ability for temperatures closer to those of the Gigabyte Super overclock? Never.

One of the beauties of the ASUS setup is its larger fan being used in a progressive way to decrease temperatures while staying extremely quiet. Basically the fan size directly impacts the amount of air movement at a lower RPM range when compared to the reference fan.


System Power Consumption


For this test we hooked up our power supply to a UPM power meter that will log the power consumption of the whole system twice every second. In order to stress the GPU as much as possible we once again use the Batch Render test in 3DMark06 and let it run for 30 minutes to determine the peak power consumption while letting the card sit at a stable Windows desktop for 30 minutes to determine the peak idle power consumption. We have also included several other tests as well.

Please note that after extensive testing, we have found that simply plugging in a power meter to a wall outlet or UPS will NOT give you accurate power consumption numbers due to slight changes in the input voltage. Thus we use a Tripp-Lite 1800W line conditioner between the 120V outlet and the power meter.

Power consumption is right in line with what we were expecting considering the extra 1GB of memory and overclocked core which distinguish the Matrix. On the other hand, it was a welcome surprise to see idle power consumption so close to a stock HD 5870.

Overclocking Results

Overclocking Results


Up until this point, our results when overclocking HD 5870 cards have been decidedly mixed with several samples failing to get more than a 10% clock speed increase. Voltage did help the situation in a number of cases but we were still setting ourselves up for disappointment when it came to overclocking the Matrix.

To say we were surprised with the final clock speeds is a massive understatement. The most likely possibility is that we got one of those few diamonds in the rough that was helped along by a stringent binning process on ASUS’ part. Even without the iTracker software’s voltage tweaks the core speeds could be pushed above the 1Ghz mark and the memory burst above the 5Ghz barrier.

Bumping the core voltage proved to be a huge step in the right direction but we were unfortunately limited by the overall temperature of the card which reached about 95C when operating at 1078Mhz. Slightly loosening the timings and bumping the voltage on the memory allowed an additional 256Mhz which is once again nothing to sneeze at and goes to highlight the advantages of a large number of options in the iTracker software.

Conclusion

Conclusion


With a cluttered market staring at them in the face, ASUS really needed to pull a rabbit out of their hats if they had any hope of releasing a card which could differentiate itself from the competition. Their HD 5870 Matrix Platinum Edition has no problem setting itself up as one of the premier cards available on the market by sporting an extremely strong feature set and more than acceptable performance. There are some issues we will get into later but for the most part this card did impress us again and again.

One of the most outstanding aspects of the Matrix is its ability to seamlessly incorporate features that will actually benefit the end user. In this vein, the iTracker software distinguishes itself as one of the best manufacturer-specific monitoring and overclocking tools on the market. Not only is it leaps and bounds better than the anemic Smart Doctor ASUS included with past cards, the control it allows is simply unmatched. With it we were able to take the Matrix to overclocking heights which were jaw dropping.

When it came to performance, the results were often mixed. This is mostly because ASUS chose to keep the core clocks of their flagship product to relatively pedestrian levels even though our sample obviously had a lot left in its tank. We understand that properly binning cores and memory to run at high clock speeds on a retail product isn’t easy but 894Mhz isn’t what we would call class-leading. As such, framerates usually bridged the gap between Gigabyte’s Super Overclock model and a reference product. The 2GB of memory may also seem to be a standout feature but in most cases it is relegated to nothing more than a fancy marketing term with absolutely no performance benefits. There are times however where this extra memory is able to shine (Metro 2033 being one of these cases) and it really has to make us wonder about its possible benefits in upcoming DX11 titles.

No matter which way you cut it, $500 is still a lot of money for what boils down to a HD 5870 with a minor speed increase. This coupled with ASUS’ release of the non-Platinum version that retails for about $30 less makes the price of this particular card a hard sell. We’d go so far as to recommend you seriously look at the non-Platinum edition if it ever becomes widely available.

Another nit we have to pick is clock speeds. Yes, it’s only 6Mhz but while ASUS advertises the Platinum as having a 900Mhz core clock, this isn’t the case. They didn’t advertise it as “almost 900Mhz”, did they? Installing the iTracker software and selecting the “Gaming” mode will give you these mostly pointless 6 extra megahertz yet why this is done is something our reps at ASUS couldn’t answer.

To finish off this conclusion it should be mentioned that there’s no such thing as perfection in our eyes. Several products have come close and the HD 5870 Matrix can easily be counted among them. All of the lessons ASUS has learned through the years seem to have been flawlessly incorporated into this card and it shines as a result. It really is a technological tour de force and while it does have its rough edges, the ASUS HD 5870 Matrix still walks away with our Dam Good Award.


Pros:

- Good performance
- Closed system cooler means hot air exhausted outside the case
- Fail-safe overclocking through iTracker and Safe Mode BIOS reset
- Driver agnostic overclocking profiles saved to BIOS
- Quiet when compared to other custom HD 5870 cards
- Stunning looks
- 2GB of memory can make a difference in some rare cases


Cons:

- Not quite the advertised 900Mhz core speed unless you install ASUS software
- Price
- Low clock speeds when compared to the competition
