Results: CPU Performance
As mentioned, Google's Nexus 10 centers on Samsung's Exynos 5 Dual SoC, formerly referred to as the 5250. The chip couples two Cortex-A15 cores running at 1.7 GHz with ARM's Mali-T604 (the number four indicating quad-core) GPU. Samsung manufacturers the Exynos 5 Dual on its 32 nm high-k metal gate process, which it says results in 30%-lower power consumption than the Exynos 4 Dual manufactured using a 45 nm node. With that said, we're curious to see how it stacks up against Qualcomm's existing S4 Plus and Nvidia's upcoming Tegra 4 SoCs, both of which benefit from a 28 nm process.
We discussed the Cortex-A15 superficially on page two of Snapdragon S4 Pro: Krait And Adreno 320, Benchmarked. Briefly, though, the -A15 employs the ARMv7 instruction set, just like ARM's Cortex-A9 design. The company claims performance up to 40% better than its prior-generation design at a given clock rate, though. Technically, a cluster of four Cortex-A15 cores supports up to 4 MB of L2 cache. But Samsung only arms its Exynos 5 Dual with 1 MB.
Geekbench doesn't reflect real-world performance; however, it's an interesting synthetic that helps demonstrate the relative performance of dissimilar platforms. According to our results, the Exynos 5 Dual's two Cortex-A15 cores deliver 80%+ more performance than the dual-core Cortex-A9s in TI's OMAP 44xx SoCs, albeit operating 500 MHz faster.
The CPU-oriented subtest helps pin down the Exynos 5 Dual's advantage in floating-point-based math (enhanced by the -A15's ability to execute 128 bits at a time), though it trails Intel's Atom Z2760 in the integer component.
But where the SoC really shines is the memory score. Samsung supports LPDDR3, DDR3, and LPDDR2 memory, but we have to imagine the Nexus 10 is armed with 2 GB of 800 MT/s LPDDR3 on its twin 32-bit channels (up to 12.8 GB/s) to post such a commanding lead over the Atom Z2760, which offers up to 6.4 GB/s of throughput via two channels of LPDDR2-800.
A T604 can be configured up to what - 8 cores? The Nexus 10 has ONE and it performs just under a PVR 543MP4
The CPU is absolutely monstrous, as is RAM Bandwidth, resolution etc..
I often think to myself - Why aren't other manufacturers sticking specs like these into their own systems? Stick a T604MP4 in there and you've got performance numbers (mind you, numbers likely not real-world) close to 2.5x that of the fastest iPad in every single way (except battery.. Lol).
As for CPU, Stick a 1.7GHz S4 Pro in there with 2GB of RAM and combine it with the same screen.
The company that does that has my next purchase guaranteed.
Values higher than that will result in the image having a blue bias. Values lower than that will result is the image appearing reddish. Of course, this also depends on the ambient light, which will influence how the image is perceived. But 6.5k Kelvin was supposedly chosen to match natural daylight.

They also used images that are so vivid and almost artificial that it's sometimes hard to tell which display is reproducing the images more faithfully.
i disagree completely.
If they want to learn how to write better video reviews, Tom's could do worse than to check out David Katzmaier's reviews, on CNet.
