Updated Rikomagic MK902II based on Rockchip RK3288 processor coming soon [Vous devez être inscrit et connecté pour voir ce lien]
The Rikomagic MK902 MiniPC, a quad-core set top box equipped with a 5 MPixels camera (under review here) should soon get updated with latest Rockchip RK3288 processor. The MK902II is expected next month, price has not yet been set. From the product release information:
Citation :
The MK902II is the latest generation Mini PC from Rikomagic, it’s faster then any of our previous Android Mini PC’s thanks to the state of the art RK3288 quad core A17 processor. Up until now (in fact the last 2 years) Mini PC’s have used Cortex A9 cores in their multi core processors. Now we can offer performance thats quite literally “Game Changing” by bringing speed increases of over 3 times our current fastest mini PCs (the MK802IV and MK902)… and they were fast!
Rockchip RK3288 Quad Core ARM Cortex-A17，up to 1.8GHZ GPU – Mali-T764 3D GPU (OpenGL ES 1.1/2.0 /3.0,and OpenCL 1.1)

As it appears on the Rikomagic MK902II board sample below, the form factor and connectors implantation seems to be identical to the MK902. The main changes on the second version relate to a major CPU upgrade with the Rockchip RK3288 processor (visible in the center of the picture) and a LAN improvement with Gigabit speeds support. The missing feature of a power switch from the MK902 does not seem to have been corrected.

In the wake of China lifting the game console ban, manufacturers across the country have started to roll out Android powered, low costs, home entertainment systems like the iSport.
The iSport takes it’s inspiration from the original Nintendo Wii and Kinect on the Xbox and can either be controlled by the Wii style motion controllers or built in motion sensing camera. The whole system comprises of a simple box which houses the camera and power/reset buttons, plus the Rockchip RK3288 processor. [Vous devez être inscrit et connecté pour voir cette image] As well as running your favourite Android games, which can be downloaded from within the built-in Alicloud operating system, the iSport can also be used for educational purposes, video streaming, and general web browsing. The iSport Android console went on sale yesterday in China for just 598 Yuan (Just below $100) which includes 2 Wii style controllers.
Quand je vois qu' un fabricant de tablettes, très proche de Rockchip, ne sortira sa tablette RK32.. que dans qques mois ( source de ce matin )... Je m'inquiète de cette isport....

Rockchip RK3288-powered Chrome OS devices on the way?
We could see Google’s browser-based Chrome OS operating system running on devices with Rockchip’s RK3288 processor soon. The Chinese chip-maker started showing off a demo of Chromium OS running on a prototype board in April, and now Google’s François Beaufort reports that there’s a new ARM development board in the Chromium OS repository featuring that same chip.
In other words, someone’s at least testing the operating system on Rockchip’s latest processor… and that means we could eventually see a Chrome OS laptop, desktop, or tablet with an RK3288 in the not-too-distant future.
The RK3288 chip is a quad-core ARM Cortex-A17 processor with ARM Mali-T764 graphics.
At this point, most Chrome OS devices feature Intel processors, although Samsung and HP offer a few models with Samsung Exynos 5 dual-core or octa-core chips. If the Rockchip-based system makes it to market, it could be one of the first ARM-based Chrome OS systems with a non-Samsung processor… although the RK3288 chip is new enough that it’s tough to say how it will stack up against Samsung’s chips in terms of performance or power consumption.
Chromium OS is the open source version of Chrome OS, and among other things, it serves as the testing ground for upcoming features, bug fixes, and performance improvements. Not every device that shows up in the Chromium code makes it to market as a real Chrome OS device… but I’m not aware of any Chromebooks or Chromeboxes that didn’t show up somewhere in the Chromium code before they officially launched, although they were usually obscured by code-names.
The code-name for the RK3288 board, by the way, is Veyron.
Here’s an early look at a Rockchip-powered Chromium OS prototype from April:

ARM Cortex A15/A17 SoCs Comparison – Nvidia Tegra K1 vs Samsung Exynos 5422 vs Rockchip RK3288 vs AllWinner A80
We’re now starting to get quite a few players with ARM Cortex A15 cores on the market, as well as some with ARM Cortex A17. So a comparison table of different quad and octa SoCs might be a useful thing to do. I’ve put aside SoCs such as HiSilicon K3V3, and OMAP5, and focused on the four latest processors: Nvidia Tegra K1 (32-bit), Samsung Exynos 5422, Rockchip RK3288 and AllWinner A80. I haven’t included Mediatek MT6595 and Qualcomm SnapDragon 805, because the two companies mainly focus on smartphones and tablets (although it appears to be slowly changing for Qualcomm), documentation is usually difficult or impossible to find, and in the case of Qualcomm they use their own ARMv7 Krait cores. [Vous devez être inscrit et connecté pour voir cette image]I’ve highlighted some features in green, in case a particular SoC appears to have an edge.

First some general comments:
As details are not always available, and I had to go through thousands of pages of documentation, it’s possible some information is incorrect or missing. So I’d be grateful if anybody points out mistakes in the tablet.
In L2 Cache = xx MB + xx KB refers to the cache for the bit processors (A15) + the cache for the LITTLE processors (A7) or the companion core.
The “Other I/Os” section is mainly for reference, as I’m sure parts are missing here.
I haven’t addressed power consumption of the different SoC, since I don’t believe numbers provided by the SoC vendors are directly comparable.
Antutu scores are interesting to get an idea of the performance, but we should bear in mind AllWinner A80 and Tegra K1 scores appear to have been achieved with development hardware, which may not have the same thermal constraints as the tablet and smartphone used with Rockchip RK3288 and Exynos 5422.
Based on this comparison table, Nvidia Tegra K1 really seems to have the best package in terms of performance, 3D and GPGPU APIs, and peripheral interfaces such as SATA and PCIe which are missing on all other SoCs. The downsides are video encoding is only supported up to 1440p, and there’s no Ethernet MAC. That means no 4K hardware video decoding, although an article from Anandtech mentioned the company demos 4K 30 fps using the Kepler GPU. The way to add Ethernet with Tegra K1 is to use an external Ethernet Control chip and connect it to the PCI Express port, as they did for Jetson TK1 development board. It’s also likely Tegra K1 is more expensive than all other three, but it’s very versatile and could be found in various type of products: tablets, mini PCs, laptops and so on. Linux and Android are supported, and since the company seem inclined to go open source, it’s likely any Linux based OS can be supported by the platform. Rockchip RK3288 should be one of the more cost effective platform in the table, but trade offs includes 1MB L2 cache (vs 2MB for others), an 4GB RAM limitation, the lack of USB 3.0 interfaces, and lower overall performance. However it’s the only SoC that 100% 4K ready here with HDMI 2.0, HEVC decode at up to 4K @ 60fps, as well as Gigabit Ethernet. ARM Cortex A17 should also have lower consumption compared to ARM Cortex A15, but it’s unclear how it will compare against big.LITTLE solution. This will probably remain a gray area because power efficiency will highly depend on the payload. RK3288 has already been demoed on hardware running Android and Chromium OS. AllWinner A80 has performance very close to Tegra K1, apparently supports VP9 (N.B: However, I had been asked to remove VP9 from an AllWinner A80 graphics once), supports 4K30 video decoding, USB 3.0. Apart from the lack of SATA and PCIe interfaces, and OpenGL 4.4 support, AllWinner SoC appears to have few drawbacks compared to Tegra K1, so we’ll have to see how it compares in terms of price versus Rockchip RK3288. The company has also announced support for 5 operating systems for A80: Android, Chrome OS, Ubuntu, Windows 8, and Firefox OS. So they must have worked with Imagination Technology to support the PowerVR GPU on these OS. Samsung Exynos 5422 appears to be just short of AllWinner A80 and Tegra K1 performance, and the company has dropped some interfaces such as SATA, PCIe, LVDS, Ethernet MAC, that makes it a little less versatile than other SoCs, and more targeted at tablets and smartphones. It’s the only SoC that supports both 8K encode and decode (H.264 and VP8 only), but lacks HEVC/H.265 hardware support. It’s also the only SoC to support eMMC 5.0, instead of just eMMC 4.5, which can potentially double the IO performance (400MB/s max instead of 200 MB/s).
Ugoos UT3 and UM3 Android TV Boxes With Rockchip RK3288 Available Soon [Vous devez être inscrit et connecté pour voir ce lien]
We’ve already seen a few RK3288 boards for upcoming Android TV boxes such asZero Devices Z6C,Sunchip TV Box and HDMI Sticks, andUgoos UT3. Most companies did not show off their complete products however, but Ugoos has now unveiled some pictures of their UT3 and UM3 Android TV boxes, and announced availability for next week. This is probably availability to resellers, but it should still mean RK3288 based TV devices should be available within a few weeks, especially since tablets such asPipo P8are already up to sale, and should start shipping within a few days.
Temperature Range – Operating: -10~40℃, Storage: -20~50℃
Humidity – 5%-90%, No condensation
Certification – CCC,CE,EMC,FCC,Wi-Fi
[Vous devez être inscrit et connecté pour voir cette image] Ugoos UT3
[size][color] Both UT3 and UM3 will be sold with a 5V/2A power adapter, an HDMI cable, and an IR remote by default. Compared to their initial specifications release, they’ve made a few changes. Rockchip RK3288 CPU frequency has been increased to 2.0 GHz (instead of 1.8 GHz), they’ve switched to HDMI 2.0 (or simply properly edited the specs), and dropped the option for 4GB RAM. The SATA port that could be seen on the PCBA does not seem to be used. They haven’t provided the dimensions, but it’s quite clear that UM3 will use a smaller form factor, and be a cheaper box without HDMI in, S/PDIF, microphone jack, nor Ethernet port, and 8GB flash instead of 16GB found in Ugoos UT3. Both devices will run Android 4.4.2. Both Android TV boxes should probably become available sometimes in June, at least for pre-order, unless the firmware is found to be too buggy by resellers.[/color][/size]

Teclast P90HD is an 8.9 inch WQXGA tablet with a RK3288 CPU
Chinese tablet maker Teclast’s latest device is one of the first tablets to ship with a Rockchip RK3288 processor. But that’s not the only thing that makes the Teclast P90HD tablet special. It also has an 8.9 inch, 2560 x 1600 pixel WXGA display, giving it even more pixels than an LG smartphone (although they’re less densely packed in the tablet). [Vous devez être inscrit et connecté pour voir cette image] The tablet is up for pre-order in China for ¥1599, or a little over $250 US. It features 2GB of RAM, 16GB of storage, an 8MP rear camera, 2MP camera, and WiFi and Bluetooth. The Teclast P90HD features Rockchip’s new quad-core ARM Cortex-A17 processor with ARM Mali-T760 graphics and the tbalet will ship with Android 4.4 KitKat software. Rockchip’s new processor isn’t actually shipping just yet, but it should be available in a few weeks when the Teclast P90HD and a number of other tablets and TV boxes with RK3288 CPU are expected to ship.

Nouveau record AnTuTu ! Et cette fois-ci ce n’est pas le Xshot Mais bien une tablette dont je vous parlais dans la Saga Pipo. La Pipo P1 et son magnifique processeur nouvelle génération, le RK3288 de Rockchip prennent ainsi le dessus sur les terminaux basés sous Qualcomm Snapdragon 801 mais aussi sur celui du désormais célèbre miPad de Xiaomi équipé du SoC Tegra K1. Avant de développer la news en détail, rappelons que le score du Xshot au-dessus de 40 000 pts a été revu à la baisse pour la version finale et s’apparente désormais à celui du Xplay 3S. [Vous devez être inscrit et connecté pour voir cette image] Des résultats AnTuTu compilés entre ces trois appareils de résolutions identiques sont sortis récemment des internets. Ils comparent la tablette PIPO P1 et le miPad de Xiaomi qui ont une résolution de 2048 x 1536 pixels mais aussi le Vivo Xplay 3S d’une résolution non égale mais similaire de 2560 x 1440 pixels. La guerre et déclarée entre les processeurs de dernière génération ! Le Snapdragon 801 MSM8974 AC (le plus puissant) du Vivo, le Tegra K1 du miPad et le RK3288 de la Pipo! Mais qui va gagner ?! [Vous devez être inscrit et connecté pour voir cette image] Sur la 3D, on attendait le RK3288 en tête car possédant le GPU monstre Mali T720 mais c’est bien le miPad prend la première place devant le SD801. Dans ce domaine ainsi que dans celui de la gestion 2D, ils se tiennent quand même dans un mouchoir de poche. Sur le plan des stats cumulé de la RAM (ram1 et ram2), le ViVo cumule environ 30% de point en plus que les deux autres qui se tiennent la cordes. Tout cela est normal car le Vivo possède 3GB de RAM et les deux autres 2GB. Notons seulement que sur la ram1, celle rendant compte de la capacité de calcul globale, le RK3288 se détache nettement du Tegra K1. Le CPU1, donnant les notes du CPU global, montre encore la Pipo P1 devant mais quasiment à égalité avec le miPad tandis que le Xplay3S est un peu derrière. Cette info n’est pas minime car c’est la première fois qu’un processeur SnapDragon 801 se fait passer devant par un autre SoC dédié aux terminaux mobiles ! En l’occurrence 2 SoC d’un coup ici. Sur la gestion d’Android pure le Rockship est encore devant mais la ou les deux autres prennent la claque de leur vie c’est dans la gestion multitâches ! le RK3288 de la Pipo P1 réussit la prouesse de scorer 12 892 pts soit 25% de plus que le Tegra K1 et quasiment 50% de plus que le SD801 du Xplay 3S !! Manque l’addition de tous ces chiffres ! Et bien les voici tout bien classés
Pipo P1 (RK3288) avec 42 593 pts WORLD RECORD mesdames et mesdames !
miPad (Tegra K1) avec 39 263 pts
Vivo Xplay3S (SnapDragon 801 74ac) avec 36 576
Alors la, les pros du chipset me disent en fronçant les sourcils : « mais bien sûr ! ils ont juste trempé la Pipo dans de l’azote liquide pour booster les résultats ! » Et là je réponds, c’est possible ! Car théoriquement une architecture ARM cortex A15 (Tegra K1) est plus puissante qu’une A17 (RK3288). Mais tout ne se joue pas que sur l’architecture ! Il y a aussi les qualités et le nombre des communications entre les cœurs et leurs affinités à travailler ensemble dans le montage du Processeur. Certes la plupart des tests observés sous AnTuTu s’élevait jusqu’ici à maximum 10 000 pts et en moyenne 6500 pts. Mais nouvelle génération oblige, le RK3288 pourrait bien changer la donne dans l’expérience Android ! Pour conclure disont que cela reste du AnTuTu, est qu’il ne faut pas non plus donner le bon dieu sans confession à la Pipo et au RK3288. Le travail logiciel des marques jour beaucoup sur l’expérience finale des utilisateurs. Pipo est solide mais aussi réputée pour avoir quelque bug mineur dans ses tablettes de générations précédentes, reste à tester cela en grandeur nature ! La première tablette sous RK3288 devrait sortir début Juin, et ce ne sera pas forcément la Pipo P1 car la marque Teclast est aussi sur le coup. Et je vous en parlerais bientôt. Etes-vous surpris par ce résultat ?
je sais pas si antutu est fiable ou si il y a overclocking, mais il est puissant, et le prix fera la différence. Sur une future tablette JXD, ça risque d'être très puissant. Par contre je suis un peu quiche en rockchip, il existe des téléphone avec cette puce 3288 ou c'est juste tablette ?

Attention au benchmark Antutu ils sont peu fiables, surtout quand ça vient d'un constructeur. Il est peu probable que le RK3288 soit meilleur que K1, ce n'est pour moi qu'impossible....Il sera à peine meilleur que le Snapdragon 800 donc Attention !

Rockchip pourrait proposer une belle surprise, de plus si Intel les a choisi pour partenaire, cela démontre qu'ils ont de quoi faire valoir
