Sounds pretty cool, look forward to seeing the 2.0Ghz benchmarks. What the hell is the VT-310? Ahh it is a dual processor board that is why the CPU benchmarks are better. It had much better CPU scores. I also wish there were more real world testing as opposed to all the synthetic benchmarks, but what can you do....
So your missing some mpeg2 or mpeg4 benchmarks, right? Well under Windows I couldn't get any codec installed that was supporting the CN700, even that good old mpeg2 codec that comes with PowerDVD 4.0 and supported the CLE266 and CN400 wasn't supporting the hardware acceleration in that chipset. CPU load under Windows and epiOS was around 25% for mpeg2 and mpeg4 but it was all done be the C7 cpu!......Performance:Well, compared to the C3 the C7 is a big step forward for VIA. You can immediatly feel the performance increase on your desktop and of course you can easily check it with some benchmarks. Even though it is only offering the performance of the Pentium III @ 800Mhz the EPIA EN15000 is twice as fast as the EPIA M10000!......Just to give you an impression the consumption of the EN board is way below the M10000 and it's twice as fast.
I think the results speak for themselves! The DB1500 built around the Geode NX 1500 (with 1GHz) processor beats out each and every competitor from VIA, and most of them by quite a margin. The memory scores show a comfortable 50% lead compared to the latest Mini-ITX boards by VIA (EN15000, SP13000, VT-310). On the CPU side of the equation the DB1500 also has a confortable advantage over the brand-new EN15000 (with the C7 CPU) while also staying in front of the VT-310. Therefore AMD's single 1GHz chip performs better than two 1GHz VIA C3 processors!
Looking at benchmark results is one thing, testing a system to check it's real-life performance another. I used my DB1500 extensively for several weeks to see how it would fare against other Mini-ITX solutions I've used in the past. I didn't experience any significant slow-downs when using the DB1500 in what I consider to be a normal work-environment (Firefox with several tabs, OpenOffice Writer, Trillian and Winamp5). When the system did feel slow it appeared to be mainly due to the limited about of RAM (I'm using the 256MB stick that came pre-installed with the board, minus 32MB for the integrated video) and not because of the processor. We all know WindowsXP likes a fair amount of RAM for itself so I guess everything would be a smooth ride with a 512MB stick.
One of the buzz-words these days is "high-definition" content so I did a quick check to see how the board performs with different types of content. I headed over to Microsoft's WMV HD Content Showcase where I downloaded two short videoclips and watched them on this system. The content was available in a resolution of 1280 x 720 (720p) or 1920 x 1080 (1080p) @ 24fps and I used WMP9 for my testing.
Speed_720.wmv: The task-manager showed around 95% CPU usage throughout the clip which turned out to be smooth most of the time. Some stutters were observed in very high-speed scenes and at the very beginning while the video is still being loaded.
Speed_1080.wmv: Content like this video encoded at 1080p was absolutely unwatchable and I was indeed reminded of the much quoted slide-show.
Based on this limited experience I would say that the DB1500 system is probably quite capable of handling 720p content. With the NX1500 CPU increasing the amount of RAM available to the system should help to smooth out the slight stutters, some software optimisations might achieve that same thing. The NX1750 processor (running at 1.4GHz) shouldn't suffer from any of these limitations. With regards to 1080p materials it is quite safe to say that one would need a significantly more potent processor (not available for this platform) or different platform altogether (Pentium-M / CoreDuo comes to mind) to handle it.
