Samsung Galaxy Alpha vs Sony Xperia Z1 Compact vs Galaxy S5 mini: specs and size comparison
We first started hearing about a metal-clad Samsung Galaxy phone in the making ages ago, or so it feels. After a hefty rumor phase, however, Samsung finally made the Galaxy Alpha official today at an impressive event in Russia, and it turns out that most of what we thought we knew about the device was right all along.

Perhaps most importantly, and to start off, the Galaxy Alpha sports a 4.7-inch AMOLED display, putting it right in-between the 4.5-inch Galaxy S5 mini and the 5.1-inch Galaxy S5. Naturally, in this day and age, this puts the Alpha on the rather short list of relatively compact devices available to consumers who aren't necessarily crazy about the continued growth of smartphone displays. Where the new Samsung device differs from most 'mini' devices, however, is the specs sheet that comes attached to it -- it sports Sony Xperia Z1 Compact-worthy hardware, though it doesn't tout water- and dust-resistance.

So how does the Galaxy Alpha compare against the two 'mini' devices mentioned above? Here's a bird's eye overview of the specs, and a look at the Alpha's relative size against them and other competitors.

IP certified

IP certified - The IP code indicates the degree of protection against dust and water. The first number represents dust protection, while the second represents water protection. In IP67, for example, 6 means a completely dust-tight device, while 7 means the device can stay immersed in up to 1 meter of water for up to 30 minutes. In IP68, a higher level of water protection is expected, but exact numbers aren't specified: both depth and continuance are specified by the manufacturer on per device basis.

Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. It’s measured in “pixels per inch”, or ppi. The higher the number, the more detailed and good-looking the display is.

312 ppi342 ppi326 ppi

Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.

System chip

System chip - Most modern handsets use an advanced chip that includes many of the device’s hardware modules like the processor, Wi-Fi, Bluetooth and sometimes even the wireless radio. This field shows what particular system chip (or System-on-a-Chip) is used in the phone.

Built-in storage

Built-in storage - Bigger storage capacity allows you to keep more content saved onto your device, such as more applications, photos or video. Games and video content typically take up the biggest amount of storage space.

Storage expansion

Storage expansion - Some handsets allow you to expand their storage capacity by using a memory expansion card – most often microSD. Expansion memory is mostly suitable for media storage, such as photo, video or music content.

Capacity - The bigger, the better! However, battery capacity is not the only factor that has an effect on battery life. Those include the chipset in use, the software running on the device, as well as the consumer's unique usage pattern.

Z1c beats out the crap out of these 2 wannabe compact!! and wait for the Z3c it'll totally blow away competition, A worthy opponent for iPhone 6.

Galaxy Alpha use Exynos 5430 is the first 20nm SoC of Samsung, so it has lower power consumption.
Exynos 5420 and Snapdragon 800&801 are 28nm process.

If Sony wants it to do well they should do their best at making it available for as many carriers as possible. I don't even think I've seen the Xperia Z1 Compact available at a US Sony Store.

I was bummed about the Xperia Z2 not making its way to Verizon.

It would be if it were really compact, without those big bezels that make it almost as big as the Galaxy Alpha with a screen 0,4" smaller.

Actually those bezels serve me well because I rely on a mod that adds gesture based UI navigation to my SZ1c. But true to be told, bezels are somehow big and SZ3c will solve that.

Spec-wise, obviously Z1 Compact has the lime light.
S5 mini is a joke.

Exynos chips have always tended to outperform Snapdragons released at about the same time.

Problem is that Cortex-A15 has been a dud in terms of power consumption, which is why it hasn't been seen in anything but a small percentage of mainline phones. Even in tablets where its poor power efficiency is less of an issue, Qualcomm Kraits have been dominating.

big.LITTLE helps a bit here, but the truth is - at peak performance, Krait is far more power efficient than the A15, which means that it takes longer for a Krait to hit thermal throttling limits and can run for longer on battery. What's the point of having that insane peak performance if you can't sustain it without overheating or killing the battery?

Snapdragons didn't have such a clear advantage when it came to Scorpion vs. Cortex-A9, or even dual-Krait vs. quad-A9 which is why Exynos 4210 and 4412 dominated Samsung's handset lineup in their heyday - but the A15 has been a failure outside of the tablet and Chromebook market.

Samsung will claim the reason for Krait dominating their handset lineup is LTE in public documentation, but the Note 2 and international LTE GS3 (I9305) proved that Samsung can hang a Qualcomm LTE modem off of an Exynos CPU.

Specs are the same

The Cpu, Gpu destroys the S805, let alone S801.

How is the Alpha a joke? The Exynos 5430 is actually more powerful than the S801 the Z3 Compact is supposed to have, and it has the same resolution display the Z3 Compact is supposed to have. And I bet it'll probably be around the same price of it too.

This is a perfect example of the lack of intelligence and double standards on phone arena. The alpha is pretty much comparable to the Z3 compact and most likely the iPhone 6 in specs, including size, yet one is mid range garbage from Samsung, and the other two are true mini flagships.

Okay there buddies.... You either need to get your head checked or at least attempt to research before you post anything.

It's not mid-range. It's overpriced. THAT is why everyone is upset. You're basically getting a lower resolution, non-water resistant GS5 without expandable storage. At nearly the same price.

The Z3C has expandable storage, is waterproof and likely has stereo speakers, maybe DNC earphones, and improved camera software. You know, stuff that actually justifies its premium price.

You should get your head checked.

Actually this has the most important advantage. The gpu/cpu is as good as it gets and it's way thinner than the fat 10.5 mm compact.

No one really cares about the so called premium things you mentioned. Lol
