Snapdragon S4 Embarasses compettion

[Cold Fussion]

Like Aberration said Snapdragon is an implementation of the ARMv7 instruction set and therefore an ARM processor in the same way Bulldozer and Sandy Bridge are both x86 processors.

Why did you quote me? ARM design the A15 cores that will be in the OMAP5 for example, Qualcomm implement the ARM instruction set into their own core design.

Right So... The new AMD vs Intel.

What is the point with multi core processors on mobile devices anyway? Unless they are reducing power draw then I dont want them.

My Lumia 800 only uses a single core 1.4 Ghz Scorpion qualcomm CPU, does everything I could possible want in a smartphone today, but the battery life is terrible.

I want better battery life first, not an uber high spec to run benchmarks on my mobile phone. The primary purpose for multi core mobile CPUs should be to reduce power draw, not to increase performance.

multiple slower cores can use much less power than a few faster cores. think if you had 4 cores at 1ghz, or 2 cores at 2ghz to do the same work, its possible it needs more than twice the energy to run only twice the speed.

Not quite... because there's going to be Qualcomm v NVIDIA (watch for their custom ARM stuff soon) v Apple v ARM Designs v Intel (x86 designs).

Not sure what Nokia did wrong there. I have essentially the same CPU... Do you have LTE? Because my Lumia 710 has insane battery life... 24+ hrs on WiFi and 17 hrs on 3G.

i think that you mean ATI people, the team stayed the same until amd sold it, and they were never merged or grouped with an amd team.



tegra3 is using the same cores as tegra2 for the cpu, so it is old. it did add things like the touch sensor chipset on the die to reduce lag and a 5th core that takes care of standby when the phone is in sleep mode, but the core design is old



qualcomm is more like intel, they make the reference core and radio, and they reject radio compatibility if you do not follow their interface design, nvidia is more like via, and samsung/ti are more like amd since they have strong floating point and gpu (they work together and use powervr gpu cores)

You know what I mean... I now refer ATI/AMD people as AMD people. Its just easier that way.

Demers was just the icing on the cake, and he was an ATI employee absorbed into AMD then let go to Qualcomm.

There is a battery charge bug on the lumia 800, and I'm waiting for upcoming tethering update before updating the phone.

The maximum charge only goes up to 1200 mah instead of 1450 mah, but its a software problem and fixable through updating the phone.

I think the 710 might have a slower processor, and definitely doesn't have the same screen quality. Everything about the Lumia 800 is perfect to me, apart from the current lack of tethering but it should be coming soon in the next update.

multicore also allows load balancing to stay in a lower pstate (lower clockspeed) and in the case of most dual cores now it lets you run all of the system on one and apps on the other like intel in the old 400mhz days.

Both have exactly same SoC, as you can see Here (Lumia 800) and Here (Lumia 710).

Only diference between the two phone's, as you said is the screen, with the lumia 800 having an Display Type AMOLED capacitive touchscreen, 16M colors
Size 480 x 800 pixels, 3.7 inches (~252 ppi pixel density) and the Lumia 710 having an Display Type TFT capacitive touchscreen, 16M colors
Size 480 x 800 pixels, 3.7 inches (~252 ppi pixel density)

amoled draws less energy so thats weird

This is relative to it's use though. And it must be addressed when talking about this.

OLED in general is more power efficient than LCD on a basis where lots of black is evident, if you turn this around towards ebook reading and browsing where most of the screen may be white, then the tables turn.
LCD has fairly even power usage, given that the backlight is pretty much constantly on, OLED turns on and off each point completely therefor being more efficient when it's mostly black.
