Video: Archos 80 Titanium Vs. Samsung Galaxy Tab 3 7.0

Can a tablet from a second-tier company, Archos, made by a company you’ve never heard of in a place you’ve never heard of, Yuanfeng in Dongguan, have any chance at all against one of the latest tablets from powerhouse Samsung, the Galaxy Tab 3 7.0?

Let’s see.

SDK 2.0 Can’t Fix Chinese Retina-Class Tablet Hardware Limits

IMP3Net has done an excellent analysis of Rockchip’s SDK 2.0 meant to improve the performance of existing 3188-based Retina-class tablets [Google English].

While certain aspects of tablet functionality are improved, the actual limitations are in the hardware — and go beyond the CPU and GPU.

Here’s some astounding info:

RK3188 memory for single-channel 32bit DDR3, in theory, the machine has a bandwidth of 0.528 × 32/8 × 2 = 4.224GB / s, the actual effective bandwidth available to smaller than this will be a lot. As we all know, domestic retina flat-panel’s screen configuration is the to imitate new iPad from. But Apple iPad 3’s 4 × 32bit LPDDR2-800 memory bandwidth of 12.8GB / s, even so in some cases iPad 3 fluency is still subject to criticism. Apple’s latest iPad 4 so the memory upgrade for the 4 × 32bit of LPDDR2-1066, bandwidth is a staggering 17.056GB / s. iPad ultra-high of memory bandwidth on a mobile platform basic yes second to none, for the retina-screen under the need to per second huge throughput is computed speaking, this is the most solid guarantee, so even is the equipped with the memory capacity twice the Yu iPad, still unable to resolve this limitation. Moreover This also is not the older ARM Mali-400MP4 heel the iPad 3 SGX543MP4, iPad 4’s SGX554MP4 high specification GPU the performance gap between, RK3188’s GPU in the 594MHz under the handling capacity is about 23.76GFLOPS, iPad 3’s 250MHz GPU for the 36GFLOPS , iPad 4’s 280MHz GPU for the 80.64GPLOPS (this data may not be entirely accurate). In terms of bandwidth bottlenecks and GPU performance under the constraints, including the RK3188, and other a lot of CPU want to truly fluency driven by retina-screen still there are tremendous pressure.

Boldfaced emphasis added by me.

Both the memory bandwidth and GPU performance of the iPad 4 are nearly four times that of currently-available Chinese Retina-class tablets based on the Rockchip 3188. So, basically, current Retina-class tablets are one-fourth of an iPad 4. That’s just staggering.
