Voy a explicar un poco como esta el tema, Aunque huawei actualizase este terminal a LOLLIPOP cosa que como dueño de uno agradecería jejejejeje, lo primero el @
Soporte Huawei de España no esta en disposición de saber si desde china, llegaran a España o Europa tan ansiado update, ya que la potestad es a nivel local para otro tipo de incidencias, los updates son todos cosa de china (probar a mandar un correo en ingles a china y recibes respuesta seguro, yo las he recibido varias veces pero demento solo que tratan de tener sus terminales al día sin especificar que modelos)...
También digo que este año parece que huawei se esta tomando muy enserio el tema de actualizar sus terminales así que paciencia..
Por otro lado esta el qualcomm 410 arquitectura "64 bits" si es arquitectura 64 bits con matices, quiere decir que muchos de sus drivers o componentes no están prepararos para los 64bits como tales porque QUALCOMM que no huawei asi lo tiene diseñado y si buscas este mismo procesador o kernels para el msm8916 (410) en 5.1.1 en otros terminales son todos 32bits de funcionamiento por lo que comento arriba qualcomm vende un procesador 64bit que no funciona a 64bit sino a 32 por ciertos componentes.( y eso si que si es culpa de qualcomm)
Por eso en opinión personal es uno procesador de lo mejor porque rinde muy bien en casos exigentes ya que siempre va por encima y los consumos son tan impresionantes.
Sobre 5.1.1 y G620s Siempre estamos la comunidad para intentar traeros las CM en su ultima versión.
Saludos y perdón por la chapa...
No entiendo porque hay que mandar un correo electrónico a china para pedir la actualización.
No entiendo que quieres decir con que es 64 bits a medias, el procesador soporta 64 bits gracias al juego de instrucciones ARM V8 y permite ejecutar tambien aplicaciones de 32 bits, ofreciendo un 20% mas de rendimiento, al tener mejoras arquitectonicas y ser 64 bits, el Cortex A57 comparandolo con el Cortex A15
" The end result is up to a 20 - 30% increase in performance over the Cortex A15 while running 32-bit code. Running 64-bit code you'll see an additional performance advantage as the 64-bit register file is far simplified compared to the 32-bit RF."
"Similarly, the Cortex A53 is a tweaked version of the Cortex A7 with 64-bit support. ARM didn't provide as many details here other than to confirm that we're still looking at a simple, in-order architecture with an 8 stage pipeline. The A53 can be used in server environments as well since it's ISA compatible with the A57."
"ARM claims that on the same process node (32nm) the Cortex A53 is able to deliver the same performance as a Cortex A9 but at roughly 60% of the die area. The performance claims apply to both integer and floating point workloads. ARM tells me that it simply reduced a lot of the buffering and data structure size, while more efficiently improving performance. From looking at Apple's Swift it's very obvious that a lot can be done simply by improving the memory interface of ARM's Cortex A9. It's possible that ARM addressed that shortcoming while balancing out the gains by removing other performance enhancing elements of the core.
Both CPU cores are able to run 32-bit and 64-bit ARM code, as well as a mix of both so long as the OS is 64-bit."
"A Brief Look at ARM's Cortex A53
ARM's Cortex A53 is a dual-issue in-order design, similar to the Cortex A7. Although the machine width is unchanged, the A53 is far more flexible in how instructions can be co-issued compared to the Cortex A7 (e.g. branch, data processing, load-store, & FP/NEON all dual-issue from both decode paths).
The A53 is fully ISA compatible with the upcoming Cortex A57, making A53 the first ARMv8 LITTLE processor (for use in big.LITTLE) configurations with an A57
The overall pipeline depth hasn't changed compared to the Cortex A7. We're still dealing with an 8-stage pipeline (3-stage fetch pipeline + 5 stage decode/execute for integer or 7 for NEON/FP). The vast majority of instructions will execute in one cycle, leaving branch prediction as a big lever for increasing performance. ARM significantly increased branch prediction accuracy with the Cortex A53, so much that it was actually leveraged in the dual-issue, out-of-order Cortex A12. ARM also improved the back end a bit, improving datapath throughput.
The result of all of this is a dual-issue design that's pushed pretty much as far as you can without going out-of-order. Below are some core-level performance numbers, all taken in AArch32 mode, comparing the Cortex A53 to its A5/A7 competitors:"
"Even ignoring any uplift from new instructions or 64-bit, the Cortex A53 is going to be substantially faster than its predecessors. I threw in hypothetical SPECint2000 numbers for a 1.2GHz Cortex A9 to put A53's performance in even better perspective. You should expect to see better performance than a Cortex A9r4 at the same frequencies, but the A9r4 is expected to hit much higher frequencies (e.g. 2.3GHz for Cortex A9 r4p1 in NVIDIA's Tegra 4i)."
"I'm really excited to see what ARM's Cortex A53 can do. It's a potent little architecture, one that I wish we'd see taken to higher clock speeds and maybe even used in higher end devices at the same time. The most obvious fit for these cores however is something like the Moto G, which presently uses the 32-bit Cortex A7. Given Qualcomm's schedule, I wouldn't be surprised to see something like a Moto G update late next year with a Snapdragon 410 inside. Adding LTE and four Cortex A53s would really make that the value smartphone to beat."
"Android 5.0 llega con soporte a procesadores de 64 bits, tanto en núcleos ARM como x86 o MIPS, manteniéndose compatible también con los procesadores de 32 bits. Incluye la nueva máquina virtual de Android, ART, que promete mejoras en el rendimiento de hasta - palabra de Google - 4 veces superiores en la respuesta."
