ARM Naming Guide (watch as I classify your device)

post #1 of 12
Thread Starter 
I think we need a bit of clarification here, since ARM is all over the map when it comes to their naming conventions.
  • Is a Cortex A8 better than Snapdragon, which is ARMv7?
  • Is an ARM 11 better than both of them?
  • Where does Apple's A4 fit in this?

To understand a little more about this you need to understand a little bit about what ARM actually does. Contrary to popular belief ARM is not actually a semiconductor manufacturer like Intel and AMD (on any noticeable scale). Instead they will license their ARM architectures to other companies, such as Texas Instruments and Qualcomm, who will then go and design their own chips based on that instruction set (OMAP and Snapdragon, respectively).

They will also sell/license premade designs (although they still have no part in the manufacturing). The Cortex A8 is one such example.

Now, ARM doesn't just design cellphone chips. Chances are pretty good that you have something in your house that is running on ARM technology. It could be your TV, your cordless phone, even your microwave, but for the purposes of this discussion I'm going to limit this to cellphones.

When it comes to mobile phones/tablets ARM currently has 3 generations of architectures, the latest being ARMv7, which succeeded ARMv6, which in turn succeeded ARMv5. Similar to i686(Pentium II+), i586(Pentium), and i386(think MS-DOS, beige boxes, and the turbo button ~nostalgia). However unlike x86, all 3 architectures sadly can still be found in today's mobile phones.

ARMv7

ARMv7, being the latest architecture, is what you're most likely to find in a mobile phone today. Pretty much everyone uses the original designs by ARM. For the most part these processors are all very close in performance. Think Phenom vs Core, which vary in core count and clock speed, but are loosely regarded as equal.

Cortex-A8
The Cortex A8 is the generic single core SoC design created by ARM. Samsung uses it in it's Hummingbird chip, Apple uses it in their latest products (although they would rather claim it as their own), Texas Instruments uses it in their OMAP lineup and Archos uses it in it's tablets.

Notable devices:
Samsung Galaxy S
Samsung Galaxy Tab
Google Nexus S
Archos 8th gen tablets (Archos 28,32,43,70,101)
Apple iPad/iPhone 4/3GS/iPod Touch 4G
Motorola Droid/Droid 2/Droid X
Palm Pre
Nokia N900




Scorpion
The Scorpion, developed by Qualcomm for their Snapdragon platform, is similar to the Cortex-A8, but where the Cortex-A8 is generic the Scorpion has been redesigned for mobile use. You will find a Scorpion at the heart of pretty much every phone HTC makes, and a handful of ones they don't wink.gif

Notable devices:
HTC Desire lineup
Google Nexus One
HTC HD2
HTC HD7/Mozart/Surround/Trophy
LG Optimus 7
Sony Xperia X10




Cortex-A9
The Cortex-A9 is the multicore version of the A8, and currently the flagship design by ARM (we'll see a bunch of these in 2011). nVidia uses it in their Tegra 2 SoC and not much more. The first phone to use it will be the LG Optimus 2X, with Qualcomm, Samsung, and TI following shortly after.

Notable devices:
LG Optimus 2X
Notion Ink Adam
Samsung Orion


Much of the confusion stems from the different combinations of these processors. With PCs you can have AMD and ATI, AMD and nVidia, Intel and ATI, and so on... its the same with mobile phones, only they also have additional chips for audio/video/etc.. The only competitor that is truly different is Qualcomm, who in addition to using their own custom CPU, use their own custom GPU (Adreno), using tech they bought from ATI. Pretty much everyone else uses PowerVR (except nVidia ofc):

Hummingbird = Cortex-A8 + PowerVR SGX 540
A4 = Cortex-A8 + PowerVR SGX 535
OMAP3 = Cortex-A8 + PowerVR SGX 530

So that basically means that the Galaxy S is faster than the iPhone 4, and the iPhone 4 is faster than the Droid, but really only when it comes to gaming.



ARMv6
The ARMv6 instruction set powered the first generation of Android devices, and sadly still remains a popular choice among low-priced smartphones. Its also a big source of confusion, thanks to ARM's oh-so-wonderful naming scheme. There is only one ARMv6 processor, which has ever misleading title of:

ARM 11
The ARM 11 is the hamster spinning the wheel inside your iPhone 1/2/3G. It is also a popular choice of Nokia, who has used it in more phones than there are people in Finland. It was also used in most pre-Nexus One Android devices. Despite what the name suggests, this is an ARMv6 cpu, which is usually running around 500mhz or lower, and is one of the primary sources of the whole "Android fragmentation" nonsense. Its slow, old, and pretty cheap to produce, so it still gets a lot of use in budget smartphones and gadgets where speed isn't a concern.

Notable Devices:
T-Mobile G1
HTC Hero/Legend
Blackberry Curve
iPhone 1G/2G/3G
iPod Touch 1G/2G
Amazon Kindle
Nokia N8, E63
Nintendo 3GS <- wat -.-


ARMv5
As if the ARMv6 weren't slow enough, we have the ARMv5, which is still seeing use in active phones, although this isn't so bad because its said phones are dirt cheap. You'll normally find ARMv5 phones using the:
ARM 9
Not to be confused with the Cortex-A9. If the ARM11 was a hamster spinning in it's wheel, then the ARM 9 is the maggots crawling around in said hamster's droppings because you're a lazy prick who never cleans the poor thing's cage. Any company that uses this in a device and calls it a smartphone needs to be smacked. You'll generally only find these on feature phones now.

Notable devices:
Nintendo DS
Nokia n-Gage
Nokia C3 (notable because it was released in 2010)
Most earlier WinMo and PocketPC phones.



And thats it. I've reduced all of this confusion into 3 simple categories of devices which for the most part can be considered identical. I hope now you understand why I find it aggravating to hear things like "Android is fragmenting", when not just Android, but the entire smartphone industry is using different hardware across their mobile OSes.


I'm sure I got some stuff wrong, and if I've omitted some devices I expect you to do your best angry fanboy impression and tell me about it.

I have a question here. I thought the entire WP7 lineup used the regular snapdragon for uniformities sake, as did really every other phone on that list. In fact, the only phones that I know of that do use it are the newer Desires (not the original) and the G2. Or am I missing something?

The WP7 lineup has a minimum requirement of a 1GHz cpu, DX9 capable GPU, and at least a 800x480 multitouch screen.

A lot of WP7 use Snapdragon simply because HTC makes a lot of WP7 devices. The Samsung Focus, for example, uses Hummingbird.

The only difference between the newer Snapdragon and the old one is a die shrink to 45nm, and a beefier GPU.


My guess as to why all of HTC's WP7s use the 65nm Snapdragon is that the 45nm Snapdragon wasn't available during WP7 development.

Focus uses a snapdragon, as does every other WP7 I've seen.

As for the newer snapdragon, they must have done something to make it faster, if the 800Mhz is equal to what used to be a 1Ghz processor.

Must be a drivers thing, which isn't surprising in a Windows product.

Hummingbird meets all of the requirements. It will even do DX 10.1.


As for the speed, what are you benching it off? (Please don't say quadrant) The newer Snapdragon's GPU is roughly 5 times as fast as the old one, which could help boost scores.
