External Graphics Upgrade for Notebooks
3D Application and HD Video Playback Benchmarks
Specviewperf is a mixed bag, with the ViDock showing some impressive gains over the integrated chipset, on average, but a couple of rogue benchmarks are showing parity with the integrated chipset. It’s quite possible that these particular benchmarks are favoring the integrated graphics’ communication speed with the system over the ViDock’s ExpressCard interface.
When it comes to HD video playback at the 1920x1080 resolution, the ViDock Pro is absolutely invaluable. Since the integrated Radeon Xpress 1150 has no HD acceleration, CPU utilization stayed close to 100%, yet playback still stuttered and was unwatchable! Contrast this with the ViDock, which allowed for HD acceleration on the GPU, removing the lion’s share of the decoding and lowering CPU utilization to about 10%. More importantly, playback was as smooth as butter.
What we didn’t notice during the smooth playback of the film is that CPU utilization was occasionally spiking to 100% and then, just as quickly, dropping back to about 10%. While this is a puzzling result, we didn’t have time for more testing. As we said, it didn’t seem to affect playback quality, but it’s something we’ll definitely be investigating in a future ViDock review.
It is very important to note that only the ViDock Pro will offer this kind of HD video acceleration; the cheaper ViDock Business edition is probably not able to accelerate HD video to this extent.
Regardless of the CPU utilization playback anomaly, the verdict is in: benchmarks show that the ViDock Pro offers a major increase in gaming performance over an integrated Radeon Xpress 1150, a major increase in performance for most professional 3D applications, and the ability to play back HD video, where the integrated solution falls flat on its face.

a 6pack in thats a nice work around for 3d graphics on laptops. but at the 429 price tag plus the price of a 8600gt or a 3870.. thats getting pricy.Reply
its a valid option, but one that a normal user should think twice about.
nice write up -
crazyhandpuppet "If your integrated video chipset doesn’t support DHCP, or doesn’t accelerate decoding, it’s not going to play Blu-ray movies."Reply
Amazing how far DHCP has come over the last few years... Looks like it's already replacing HDCP :) -
cleeve Call of Duty 4 is so much easier on hardware, I prefer to concentrate on stuff that will really challenge it like Crysis and SupCom so we have a worst-case scenario.Reply -
piratepast40 There are several interesting points here. The fact that card compatability is dependant on chipset type is interesting but not really shocking. It's (sort of) similar to the hybrid SLI and Crossfire capability of the 780 series chipsets and the way the chipsets support specific GPU series. It sounds as though another header or bus type is needed to fully support the concept. The expresscard/USB bus was the holdup a year ago and it appears to still be the main bottleneck. I'm curious to see if AMD's PUMA platform or Intel's version (forgot the name) will show us something in this area. Am also wondering if one of the laptop OEM's might offer the external card setup for specific models of their computers. Will be interesting to see what others are doing. Haven't heard anything at all from ASUS since early last year.Reply -
spuddyt would it be possible to run crossfire/sli with two of these things? (largely out of curiosity, twould be insane to actuall sensibly do it...) That way wouldn't you have 2 seperate pcie 1x bandwidths to play with/Reply -
anonymous x aww, i wish the express card slot had enough bandwidth to suport a geforce 9800 cardReply
