Dual-core ARM battle: RockChip’s RK3168 vs Allwinner’s A20

Two of China’s most popular chip brands, RockChip and Allwinner, are going at it again with new dual-core processor designs – RockChip with its RK3168 and Allwinner pushing its A20.
The two main differences are that while the A20 features the new low-power Cortex A7 design, Rockchip’s RK3168 uses the more powerful Cortex A9. ¬†Somewhat detracting from the A20 is that it uses a 40-nanometre production process, compared with RockChip’s 28nm build, so while the A20 might use a more efficient CPU design, the RK3168 uses a more efficient build, which is likely to cancel each other out in terms of power consumption.… Read more

[CPU] Rockchip RK3168: is it better than the RK3066?

Chinese ARM developer RockChip has had a number of wins in the last 12 months or so, first with its dual-core RK3066 Cortex A9 processor, followed by its quad-core RK3188, now appearing in a large number of Android TV sticks such as the CX-919. Now comes its new second-generation Cortex A9 dual-core processor dubbed the RK3168.
The new dual-core RK3168 features the same Cortex A9 processor design as the RK3066 but drops the ARM Mali-400 MP4 quad graphics cores running at 250MHz, in favour of a single-core PowerVR SGX540 we believe to be ticking over at 400MHz.… Read more

New 3D imaging chips allow for touchless gesture recognition

Microsoft’s Kinect sensor may well be the world’s most recognisable gesture recognition device, but take the idea, shrink it down into a single chip and you have the new 3D sensor chip family developed by German fabless designer Infineon Technologies.
The new chips take a 3D imaging sensor array and combine it with conversion and control functions to produce a compact, single lens system, which Infineon says is ripe for PC and consumer electronics applications.… Read more

MediaTek launches MT8125 quad-core Cortex A7 processor for phones/tablets

Back when chip maker ARM launched its new big.LITTLE dual-chip strategy in late 2012, the big noise was around the upcoming Cortex A15 architecture. Sure, the smaller Cortex A7 would run as an SoC (system on a chip) in its own right but it was seen as a companion processor to allow significant power consumption improvements by offloading tasks from the larger to the smaller chip.… Read more

Intel release new N2805, N2810, N2910 processors

With Intel set to launch its up-coming Haswell processor family in the coming days, the chip giant is still pumping out what we think are Ivy Bridge-class 22-nanometre CPUs, albeit in the low-power Celeron-M range.
The new N2805, N2810 and N2910 chips were announced earlier this week with exactly zero fanfare, appearing the form of a new price list. According to CPU World, the N2800-series chips feature dual-core with no HyperThreading and 1MB of last-level cache (LLC).… Read more

How they compare: Rockchip RK3188 vs Allwinner A31

If you’re on the lookout for a new budget tablet or phone, two of the more popular quad-core CPU options you’ll find at the moment are the RK3188 from Rockchip and Allwinner’s A31.
These CPUs are often pitted against each other, however, they’re very different devices, not only in terms of architecture but also their GPU and manufacturing process.
Rockchip has gone with a smaller 28-nanometre process node on the RK3188 compared with the A31′s 40nm option, which allows Rockchip to either gain reduced power consumption or a higher clock speed for a given TDP (thermal design power).… Read more
