Eurocom Panther 5D Notebook Review: Faster Than Your Desktop

Testing For Thermal Throttling

System Throttling

Running Prime95 and FurMark at the same time places a very high load on any system, with both the CPU and GPU drawing maximum power while also generating maximum heat. The Panther 5D's CPU is rated for up to 150 W and the each of the GPUs are at least 100 W. Add in 25-50 W for the desktop platform components and you're looking at 400 W or more. Obviously, that's significantly more power than most notebooks draw, and the reason why Eurocom needs to offer dual power adapters. If the system can't get more than 400 W from its supplies, or isn't able to dissipate that amount of heat efficiently, it will throttle the CPU, GPU, or both in order to honor its thermal and electrical specifications.

Synthetic Heat Run

In order to really push the Panther 5D to its limits, we fully load its Core i7-3970X CPU and both GeForce GTX 680M GPUs. The goal is to tax the machine until its internal and external temperatures plateau. The only reason to end a run early is a hardware failure.

In the chart above, you can see the load and temperatures for the CPU and both GPUs.

The CPU took 12 minutes to heat up both of its big copper sinks enough that the fans were spinning at their highest rotational speeds. You can see the slight dip between the 12- and 14-minute mark where the amount of air being drawn in momentarily pulled temps down a bit.

At the 60-minute mark, I shut down FurMark to alleviate the GPU load, dropping them to idle. The CPU temps were unaffected. It was not until I also shut down Prime95 at 65 minutes that the thermals started to relax.

The two CPU fans are on the right half of the computer. When they both kick in, the amount of air they move is startling the first time you feel it.

After close to 20 minutes, the CPU hit 90 °C and throttled down to 3.4 GHz. It stayed at that clock rate for most of the remaining run.

You can see the CPU's clock rate through our run in the chart above.

The first GPU is located next to the GPU, and it sits in the middle of the machine. Its air intake is third from the left. Cooling that graphics processor is naturally a little more difficult, so its temperatures were a few degrees higher than the second GPU, situated all the way to the right.

With that said, neither GPU ran particularly hot during our test, even though they were both fully-loaded for an hour. In the 70-minute graph, you can see a slight dip in their temperatures, which was caused by lifting the machine to measure heat on the desktop under it.

Both GPUs maintained their minimum clock rate during testing.

We saw power drawn from the wall peak at 464 W. Allowing for 10% losses at the power adapters, this means that the Panther 5D was dissipating more than 400 W. Even the power adapters themselves heat up quite a bit. It's naturally important to keep everything around Eurocom's machine well-ventilated if it's under a demanding load.

Then again, we didn't see temperatures spike so high in any real-world workload we through at the Panther 5D.

    I want the satisfaction of just dropping this monster on someone's desk, and say

    "personal server: DEPLOY!"

    Great for individuals that moves around often (i.e LAN parties, get togethers, etc) IF the hardware can be kept cool AND if the fan doesn't sound like a space rocket taking off. However, one will need a deep pocket to afford something like this.

    Sure it's better than my desktop, but it's also three times more expensive!

    now this is how you're meant to play crisis 1-2-3 right by any one with an iMac.

    the main people i can see needing this bad boy is division commanders on a battlefield as well as NSA hackers and CIA spies and Drone operators

    you guys didn't review the sound volume :(
    but what i really wanted to see was the effects of ocing the gtx 680Ms :P

    Great article. Puts my 17.3 inch laptop to shame.

    Finally I can have high end desktop performance on the go.

    I once had a Desktop Replacement laptop, huge monster that required a large AC adapter, was loud and heavy. These things are NOT portable, they are heavy to lug around and completely impractical for mobility. They are for people who, for whatever reason, do not want a desktop +monitor at their house. These are just desktops that are easier to transport around.

    This seems more for bragging rights. Sure some people will NEED this... For a portable gaming system with 3 power-bricks, etc... why not get customized AIO? Or simply brink a small (SFF) case with keyboard and 20" display which would weight less? If you're gaming anyway - you'll need a mouse. The keyboard looks crappy, the numeric keypad is up against the main keys.

    Lets see, a SFF setup parts:
    PC: 5 = SFF-PC, keyboard, mouse, monitor, 2 power cords.
    5D: 7 = 5D Panther, Mouse, 2 power cords, 3 power bricks/converter.

    In return, you get a much better keyboard... then when broken, its a $10~150 replacement...

    It may be fast, but it sure look ugly. If i compare this notebook to a car, it will be a Mitsuoka Orochi.

    awesome photography. i enjoyed looking at the parts.
