Rendering and Scientific

CineBench 11.5

This rendering benchmark based off of the Cinema 4D engine is a terrific indicator for multi-threaded processing.

If we first look at the single threaded results, you'll see that the new Jaguar core running at 1.5 GHz is about 75% slower than the Ivy Bridge core running at 1.9 GHz or so.  Powering on all the cores (two with HyperThreading on the 3227U, four on the A4-5000) we see the difference in performance is only 21% - the advantage of four cores versus two cores with HT. 

POV-Ray 3.7

POV-Ray has long been the poster child for multi-threaded processing and rendering.

Another good showing for the A4-5000 here though of course it is slower than the Core i3-2105 desktop part.

Euler 3D Fluid Dynamics

This fluid dynamics simulation is very CPU and memory intensive.  From the benchmark source website:

The benchmark testcase is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes. Figure 1 shows the CFD predicted Mach contours for a freestream Mach number of 0.960.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. Our benchmark score is reported as a CFD cycle frequency in Hertz.

The Euler3D fluid dynamics testing results show good scaling from 1 to 2 to 4 threads of processing (81% and 61% jumps respectively) on the Kabini / Jaguar architecture.

Dirt3 looked like it was stuttering ; )

It was pretty smooth in playing it today.  Even Bioshock at 720p kind of impressed me.

Could have been YT playback or capture causing a stutter; anything really with streaming video!

I currently have a Windows 8 desktop system running on an E-350 that I am using as a home server and I'm quite happy with it. These chips are good for laptops, obviously, but can also be well suited, IMO, to low powered home servers. I'm not running a ton of stuff on mine, just some software raid like stuff (drive bender), some offsite backup software, FTP server etc. But there is a market for low powered devices. The challenge when you are using it like I am, primarily as a NAS with a bunch of redundancy on it, is getting enough sata ports, or expansion slots that you can add sata cards into.

I don't find myself using a laptop a ton anymore with my tablet, but a cheaper device with this level of performance would be easier to justify, for those times I do want/need more than the tablet.

whats the transistor count ? and how come the xbox is talking 5 billion transistor count ? on the same-ish technology ? and yet is still based on jaguar cores ? much larger die with ramped up graphics portion and 8 cores ?, or are the PS4 and xbox counting hyper threading cores, as extra cores ? or are they completely different jaguar core apus as yet unseen ? that wont be released to the public ?

xbox1/ps4 have stronger and bigger gpu

Ivy Bridge Ultrabook reference battery capacity isn't 66.8WHr.
It's 49Whr,right?
